controller option for time vs. temp./process (ramp/soak) and special batch/recipe applications ? square root extraction for flow sensor applications general description the model dlc, dual loop controller, is a full featured, din rail mounted, dual input pid controller. the dlc is designed as a modular building block for multi-zone process control applications. the controller has two independent a & b input channels. each channels input can be configured to accept a wide range of thermocouple, rtd, 0-10 v, 0/4-20 ma, or resistive signals. each channel can also be configured to extract the square root of the input in both process voltage or process current modes for applications such as flow measurement using a differential flow sensor. channel b can be assigned as a remote setpoint for channel a. the two time-proportioning or dc analog outputs can be programmed to control two independent processes. the two alarms per channel can be configured for various alarm modes, or provide a secondary control output for heat/cool applications. the control and alarm outputs are n channel open drain mosfets capable of switching up to 1 amp dc. for applications requiring larger loads or a/c loads, several din rail mount relays are available. the controller operates in the pid control mode for both heating and cooling, with on-demand auto-tune, that establishes the tuning constants. the pid tuning constants may be fine-tuned through the serial interface. the controller employs a unique overshoot suppression feature, which allows the quickest response without excessive overshoot. the controller can be transferred to operate in the manual mode, providing the operator with direct control of the output, or the on/off control mode with adjustable hysteresis. the controllers high density packaging and din rail mounting saves time and panel space. the controller snaps easily onto standard top hat (t) profile din rails. safety summary all safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. if equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. do not use the controller to directly command motors, valves, or other actuators not equipped with safeguards. to do so can be potentially harmful to persons or equipment in the event of a fault to the controller. an independent and redundant temperature limit indicator with alarm outputs is strongly recommended. alarms the dlcs two solid -state alarms can be configured independently for absolute high or low acting with balanced or unbalanced hysteresis. they can also be configured for deviation and band alarm. in these modes, the alarm trigger values track the setpoint value. adjustable alarm trip delays can be used for delaying output response. the alarms can be programmed for automatic or latching operation. latched alarms must be reset with a serial command. a standby feature suppresses the alarm during power-up until the temperature stabilizes outside the alarm region. the outputs can also be manually controlled with modbus register or coil com mands. setpoint controller option the setpoint controller option is suitable for time vs. temperature/process control applications. the controller allows a profile of up to 20 ramp/soak segments. profile conformity is assured by using the error band mode and error band parameter. the profile cycle count allows the profile to run continuously or a fixed number of cycles. power-on options automatically stop, abort, start, resume, or pause a running profile. ordering information

2 communications the rs485 serial communications allows the dlc to be multi-dropped, with baud rates up to 38400. the cbpro007 programming cable converts the rs232 port of a pc to rs485 and is terminated with an rj11 connector. the bi-directional capability of the cbpro007 allows it to be used as a permanent interface cable as well as a programming cable. software the dlc is programmed with windows ? based sfdlc software. the software allows configuration and storage of dlc program files, as well as calibration. additionally, all setup and control parameters can be interrogated and modified through modbus ? register and coil commands. analog output option the optional dual dc analog output (10 v or 20 ma) can be independently configured and scaled for control or re-transmission purposes. these outputs can be assigned to separate channels, or both outputs can be assigned to the same channel. programmable output update time reduces valve or actuator activity. specifications 1. power : 18 to 36 vdc, 13 w (4 w if +24 vdc output excitation is unused) 24 vac, 10% 50/60 hz, 15 va (7 va if +24 vdc output excitation is unused) must use a class 2 or selv rated power supply. 2. +24 vdc output power : 24 vdc, +15%, -5%, 200 ma max 3. memory : non-volatile memory retains all programmable parameters. 4. input : sample time : 100 msec (9.5 hz) failed sensor response : open or shorted (rtd only) sensor coils indication, error code returned in process value common mode rejection : >110 db, 50/60 hz normal mode rejection : >40 db, 50/60 hz temperature coefficient : 0.013%/c overvoltage : 50 vdc max step response time : 300 msec typ., 400 msec max 5. thermocouple inputs : types : t, e, j, k, r, s, b, n, c, linear mv input impedance : 20 m ?

4 step 1 setting the jumpers and dip switches the jumpers are accessible from the bottom of the controller. needle-nose pliers are needed to remove the jumpers. they should be set prior to installation. to insure proper operation, the jumpers must match the controller software configuration. analog dc outputs (optional) analog output 1 and analog output 2 can be configured for voltage (v) or current (i), independent of each other. both v/i + and v/i - jumpers of the same channel must be set for the same type of output signal. inputs channel a and channel b can be configured independent of each other. jumper position can be ignored for thermocouple and millivolt inputs. i2- v2+ i2- v2+ i1- v1+ i1- v1+ analog output 2 jumpers analog output 1 jumpers 10v 20ma rt d 10v 20ma rt d channel a input channel b input channel b input jumpers channel a input jumpers analog output 2 jumpers (current ) analog output 1 jumpers (current ) (rtd) (as set from factory) emc installation guidelines although red lion controls products are designed with a high degree of immunity to electromagnetic interference (emi), proper installation and wiring methods must be followed to ensure compatibility in each application. the type of the electrical noise, source or coupling method into a unit may be different for various installations. cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. listed are some emi guidelines for a successful installation in an industrial environment. 1. a unit should be mounted in a metal enclosure, which is properly connected to protective earth. 2. use shielded cables for all signal and control inputs. the shield connection should be made as short as possible. the connection point for the shield depends somewhat upon the application. listed below are the recommended methods of connecting the shield, in order of their effectiveness. a. connect the shield to earth ground (protective earth) at one end where the unit is mounted. b. connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1 mhz. 3. never run signal or control cables in the same conduit or raceway with ac power lines, conductors, feeding motors, solenoids, scr controls, and heaters, etc. the cables should be run through metal conduit that is properly grounded. this is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. also, signal or control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components. 4. long cable runs are more susceptible to emi pickup than short cable runs. 5. in extremely high emi environments, the use of external emi suppression devices such as ferrite suppression cores for signal and control cables is effective. the following emi suppression devices (or equivalent) are recommended: fair-rite part number 0443167251 (red lion controls #fcor0000) line filters for input power cables: schaffner # fn2010-1/07 (red lion controls #lfil0000) 6. to protect relay contacts that control inductive loads and to minimize radiated and conducted noise (emi), some type of contact protection network is normally installed across the load, the contacts or both. the most effective location is across the load. a. using a snubber, which is a resistor-capacitor (rc) network or metal oxide varistor (mov) across an ac inductive load is very effective at reducing emi and increasing relay contact life. b. if a dc inductive load (such as a dc relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. one of the most effective ways is to place a diode across the inductive load. most red lion products with solid state outputs have internal zener diode protection. however external diode protection at the load is always a good design practice to limit emi. although the use of a snubber or varistor could be used. red lion part numbers: snubber: snub0000 varistor: ils11500 or ils23000 7. care should be taken when connecting input and output devices to the instrument. when a separate input and output common is provided, they should not be mixed. therefore a sensor common should not be connected to an output common. this would cause emi on the sensitive input common, which could affect the instruments operation. visit http://www.redlion.net/emi for more information on emi guidelines, safety and ce issues as they relate to red lion products. serial dip switch settings the dlc serial communications settings can be set via dip switches or through the serial communications port (software selectable). the software selectable serial settings method using the serial communications port must be set using rlcpro or another software program to write to the dlc modbus registers (40401-40407). when using the dip switches to configure the serial settings, the modbus mode is limited to rtu mode only. sw a baud ra te p arity def ault m2802x swb: address x32 x128 x64 x4 x16 x8 x1 x2 m2802 x x64 x32 swb: address x4 x1 x2 x16 x8 x128 sw a defa ul t pa rity baud ra te

(pull wire to verify tightness.) each terminal can accept up to one #14 awg (2.55 mm), two #18 awg (1.02 mm), or four #20 awg (0.61 mm) wires. controller power connections for best results, the power should be relatively clean and within the specified limits. drawing power from heavily loaded circuits or from circuits that also power loads that cycle on and off should be avoided. it is recommended that power supplied to the controller be protected by a fuse or circuit breaker.

8 step 8 programming the input setup input type (40101/40201) : select the proper input type from the pull down menu. make sure the input jumpers are set to match the input signal selection. scale (40102/40202) : select either degrees fahrenheit or celsius. for mv, resistance, voltage or current types, this has no effect. if changed, check all temperature related values, as the dlc does not automatically convert these values. resolution (40103/40203) : for all temperature and ohms input types low (x1) resolution selects whole units of measure. in these same modes, high (x10) resolution selects tenth of units of measure. for mv mode, low selects tenths of mv and high selects hundredths of mv. if changed, be sure to check all parameters because the controller does not automatically convert related parameter values. for voltage or current types, this has no effect. rounding (40104/40204) : rounding selections other than 1 cause the process value to round to the nearest rounding increment selected. (for example, rounding of 5 causes 122 to round to 120 and 123 to round to 125.) rounding starts at the least significant digit of the process value. if the signal is inherently jittery, the process value may be rounded to a value higher than 1. if the range of the signal exceeds the required resolution (for example, 0-1000 psi, but only 10 psi resolution is required), a rounding increment of 10 will effectively make the reading more stable. digital filtering (40105/40205) : the filter is an adaptive digital filter that discriminates between measurement noise and actual process changes. if the signal is varying too greatly due to measurement noise, increase the filter value. if the fastest controller response is needed, decrease the filter value. span correction (40106/40206) : this value is the correction slope. a span of 1.0000 applies no correction. span only applies to temperature sensor, millivolt, and ohms inputs. offset correction (40107/40207) : this value offsets the temperature value by the entered amount. offset only applies to temperature sensor, millivolt, and ohms inputs channel b assignment (40198) : this is used to configure channel b to operate as a remote setpoint to channel a. channel b pid control is not functional when the input is assigned as a remote setpoint. step 7 programming the pid settings note: the register numbers correspond to (channel a/channel b).channel b pid control is not functional when the input is assigned as a remote setpoint. the auto-tune procedure of the controller sets the proportional band, integral time, derivative time, digital filter, control ouput dampening time, and relative gain (heat/cool) values appropriate to the characteristics of the process. proportional band (40007/40023) : proportional band, entered as percent of full input range, is the band from the setpoint where the controller adjusts the percent output power based on how close the process value is to the setpoint. for temperature inputs, the input range is fixed per the entered thermocouple or rtd type. for process inputs, the input range is the difference between the entered process low scaling value and the process high scaling value. the proportional band should be set to obtain the best response to a process disturbance while minimizing overshoot. a proportional band of 0.0% forces the controller into on/off control with its characteristic cycling at setpoint. integral time (40008/40024) : integral time is defined as the time, in seconds, it takes the output power due to integral action alone to equal the output power due to proportional action alone during a constant process error. as long as the error exists, integral action repeats the proportional action each integral time. integral action shifts the center point position of the proportional band to eliminate error in the steady state. the higher the integral time, the slower the response. the optimal integral time is best determined during pid tuning. if time is set to zero, the previous integral output power value is maintained. offset power can be used to provide manual reset. integral action can be disabled by writing a 1 to the disable intergral action register (40044/40052). derivative time (40009/40025) : derivative time, entered as seconds per repeat, is the time that the controller looks ahead at the ramping error to see what the proportional contribution will be and it matches that value every derivative time. as long as the ramping error exists, the derivative action is repeated by proportional action every derivative time. increasing the derivative time helps to stabilize the response, but too high of a derivative time, coupled with noisy signal processes, may cause the output to fluctuate too greatly, yielding poor control. setting the time to zero disables derivative action. control mode (40041/40049) : in automatic mode, the percentage of output power is automatically determined by pid or on/off control. in manual mode, the percentage of output power is entered manually. for more information, see control mode explanations section. output power (40005/40021) : this parameter can only be changed by direct entry in manual mode. for more details on this parameter, see the control mode explanations section. offset power (manual reset) (40010/40026) : if the integral time is set to zero (automatic reset is off), it may be necessary to modify the output power to eliminate errors in the steady state. the offset power is used to shift the proportional band to compensate for errors in the steady state. if integral action is later invoked, the controller will re-calculate the internal integral value to provide bumpless transfer. auto-tune code (40013/40029) : prior to starting auto-tune, this code should be set to achieve the necessary dampening level under pid control. when set to zero, it yields the fastest process response with possible overshoot. a setting of 2 yields the slowest response with the least amount of overshoot. if the auto-tune code is changed, auto-tune needs to be reinitiated for the changes to affect the pid settings. auto-tune is initiated by writing a 1 to the auto-tune start register (40011/40027). the auto-tune phase will be shown in register (40012/40028). for more information, see pid tuning explanations section.
9 step 9 programming the setpoints setpoint (40002/40018) : enter the setpoint value. deviation of process value (40001/40017) from setpoint value can be viewed in the setpoint deviation register (40006/40022). low limit (40108/40208) ; high limit (40109/40209) : the controller has programmable high and low setpoint limit values to restrict the setting range of the setpoint. set the limits so that the setpoint value cannot be set outside the safe operating area of the process. ramp rate (40110/40210) : the setpoint ramp rate can reduce sudden shock to the process and reduce overshoot on startup or after setpoint changes, by ramping the setpoint at a controlled rate. the ramp rate is 0.1 for input types 0-11, 0.1 ? for input type 12, 0.01 for input type 13, and 0.1 unit for input types 14-15 per minute. writing a 0 disables setpoint ramping. the disable setpoint ramping register (40042/40050) can also be used to disable ramping. the setpoint ramping in-process register (40043/40051) will be a 1 during setpoint ramping. while ramping is enabled, the ramping setpoint can be viewed in register (40045/40053). the ramp rate for chb is not functional when it is assigned as a remote setpoint input. once the ramping setpoint reaches the target setpoint, the setpoint ramp rate disengages until the setpoint is changed again. if the ramp value is changed during ramping, the new ramp rate takes effect. if the setpoint is ramping prior to starting auto-tune, the ramping is suspended during auto-tune and then resumed afterward using the present process value as a starting value. deviation and band alarms are relative to the target setpoint, not the ramping setpoint. a slow process may not track the programmed setpoint rate. at power-up, the ramping setpoint is initialized to the starting process value. remote/local setpoint select (40046) : channel a setpoint mode can be switched between local setpoint operation and remote setpoint operation. the channel b input must be assigned as a remote setpoint (register 40198). step 10 programming profile setup (optional) local/remote setpoint transfer mode (40199) : when cycling from/to local or remote setpoint (register 40046), the response of the controller can be programmed to act in a variety of ways. the table summarizes the responses for setpoint transfer options. local/remote setpoint transfer mode local to remote remote to local 0 - normal output may bump. output may bump. 1 - auto no output bump. process error eliminated at rate of integral action. ramping disabled during transfer. no output bump. process error eliminated at rate of integral action. ramping disabled during transfer. 2 - track output may bump. local setpoint (40002) assumes value of remote setpoint (tracks). no output bump. note: in situations where an output bump may occur, the setpoint ramp function can be used to reduce or eliminate bumping when switching setpoint modes. the setpoint ramp feature ramps the setpoint from the old setpoint to the new setpoint. remote setpoint ratio multiplier (40206) : this value is used for channel b when it is assigned as a remote setpoint input. the ratio multiplier applies to all input types (0-15). remote setpoint bias offset (40207) : this value is used for channel b when it is assigned as a remote setpoint input. scaling points (40111-40114/40211-40214) : low and high scaling points are necessary to scale the controller for process voltage and current inputs. each scaling point has a coordinate pair of input and process value entries. the process value will be linear between and continue past the entries up to the limit of the input range. reverse acting measurement can be accomplished by reversing the input or process entries, but not both. (do not reverse the input wires to change the action.) to scale a 4-20 ma input signal to provide process values of 0 to 100.00 (% in hundredths), the input low (40113/40213) and input high (40114/40214) values would be 4000 and 20000 (0.001 ma resolution), and the process low (40111/40211) and process high (40112/40212) values would be 0 and 10000. process decimal point (dec pt) (40115/40215) : the decimal point position is used to enable sfdlc display in desired engineering units for voltage and current process values. it is not used internally by the dlc. profile power cycle mode (40321/40421) : upon controller power-on several profile operating modes exist. stop : if the profile was running when powered down, upon power-up, "stop" places the profile into the stop or off mode, regardless of the mode prior to the power-down. the active setpoint is the setpoint of the last segment that ran before power-down. abort : if the profile status was running, paused, or in error delay when powered down, upon power-up, "abort" will place the controller in manual mode at 0% output power. the setpoint and ramp rate are the values they were prior to running the profile. if the setpoint controller was 'paused,' they will be set to the values that they were at power-down. start: the start power cycle mode causes the controller to automatically start the profile at power-up. this will occur if the unit was in manual or automatic control mode. during maintenance or at other times when this action is not desired, the profile power cycle mode should be changed appropriately. resume : at power-up, resume causes the profile to continue from the point and phase when power was removed. if the unit was in ramp phase, the ramping setpoint will start ramping from the initial process value at power-up. pause : upon power-up, the controller pauses and maintains control at the initial process value (on power-up), at the phase where the controller was powered down. the user can then determine how to proceed based on the process that is being controlled.
profile error band mode (guaranteed soak) (40322/40422) : profile conformity can be assured by using the profile error band mode and error band parameter. if the process value deviates outside the error band value while a profile is running, the controller enters the delay mode. in the delay mode, the profile phase timer is held (delayed) until the process value is within the deviation error band value - the error band hysteresis value. at this time, the profile continues running unless the process value again deviates. these actions assure that the actual process value conforms to the profile. disable error band : error band operation is disabled. ramp phase only error band : the profile error band only applies to the ramp phases of the running profile. hold phase only error band : the profile error band only applies to hold phases of the running profile. ramp & hold phase error band : the profile error band applies to both ramp and hold phases of the running profile. profile error band (40323/40423) : during a hold phase, the profile is paused when the process error is >= the profile error band. the profile will remain paused until the process error (deviation) is within the profile error band (error band-error band hysteresis). profile error band hysteresis (40324/40424) : controls the process value at which the profile will come out of an error band delay. if in error band delay, the profile phase timer is held (delayed) until the process value is within the deviation error band value - the error band hysteresis value. profile end segment (40325/40425) : the profile end segment indicates the last segment (i.e., the number of segments to be used in a profile) that is to be ran in the profile before it stops or re-starts (dependent on profile cycle count/profile cycle count remaining). profile cycle count (40326/40426) : once a profile is started, it runs the number of cycles programmed in this register and then automatically defaults to the profile end control mode. if this parameter is changed while the profile is active, the new value (if less than 250) will not take effect until the profile is stopped and re-started. if the profile cycle count is set to 250 (continuous profile cycling), the change will take affect immediately. profile end control mode (40327/40427) : this parameter sets the type of control action that will be used when the number of profile cycles as programmed in the profile cycle count parameter has run to completion. control outputs off : control is turned off by putting the controller in manual mode at 0% power. control can be resumed by changing the control mode (40041/40049) to automatic. automatic : when configured for automatic the controller will continue controlling at the last setpoint value. setpoint controller setpoint segment registers 1-20 (40601-40620[cha]/40701- 40720[chb]): the setpoints for the profile are written in these registers. the values are limited by the setpoint lo and setpoint hi limits registers. register (40601/40701) is the setpoint for the 1st segment of the profile. setpoint controller ramp rate segment registers 1-20 (40621-40640[cha]/40721- 40740[chb]): the ramp rates for the profile are written in these registers. register (40621/40721) is the ramp rate for the 1st segment of the profile. a ramp rate of 0 disables setpoint ramping. setpoint controller hold time segment registers 1-20 (40641-40660[cha]/40741- 40760[chb]) : the hold times for the profile are written in these registers. register (40641/40741) is the hold time for the 1st segment of the profile. segment hold times of 0 can be used to achieve a ramp with multiple slopes. profile operating status/mode (40065/40073 ) stop/off : the stop/off status indicates the profile is dormant or off. a profile can be stopped by setting this register to 0, by allowing a profile to run to completion, or by removing and re-applying power when the power cycle mode is configured for stop. if the profile was terminated during a ramp phase, the unit will continue to ramp to the active setpoint. abort : abort is a command action that can be used quickly to stop the profile and turn off the control outputs. the controller is placed into manual mode at 0% output power. following the abort command the profile operating status will go to 0 (stop/off). run/start : the profile is in the run mode when it is executing. while running, the profile can be stopped (0), paused (3), or advanced to the next phase. a profile can be started and placed into the run mode automatically when the controller is powered-up (see profile power cycle mode). if the profile was previously stopped, when it is placed in to the run/start mode (2), the controller will be put into automatic control (if it was in manual) and start the profile at the first segment. if the controller was in manual mode prior to starting the profile, the controller will start ramping from the current process value. if the profile was "paused," it will resume operation. the advancement of the profile can be viewed in the profile phase (40066/40074) and profile segment register (40067/40075). 10 step 11 monitoring profile operation (optional)
11 pause : pause signifies that a profile is active but the time base (profile phase timer) is paused. the pause mode can only be invoked by writing a 3 in the profile operating status register. pausing a profile during a ramp phase pauses the ramp and the controller maintains control at the ramping setpoint value (40045/40053) at the instant of the pause action. the use of pause, effectively lengthens the total run time of a profile. the unit will remain in pause mode until it is placed back in the run mode by writing a 2 (run/start) into the profile operating status register. error delay (guaranteed soak) : the error delay setting is used only as a status indication. it indicates that a profile is active but the phase timer or profile advancement has stopped. this is caused by automatic action of the controller when the process deviates more than a specified amount from the active profile segment. the error delay is similar to pause, except the error delay status can only be invoked automatically. see "profile error band mode (40322/40422)." do not write a "4 - error delay," to the profile operating status register. doing so will instead put the controller in pause mode (3). profile phase (40066/40074) : when the profile is active, this register indicates whether the controller is in a ramp (0) or hold (1) phase. profile segment (40067/40075) : indicates the current active segment while the profile is running. a zero indicates that the profile is stopped or off. profile phase timer (40068/40076) : this register shows the remaining segment phase time in 10ths of minutes. the remaining phase time can be changed "on the fly" to accelerate or decelerate the phase time. the change in phase time will only affect the running profile and not the stored parameters. if the phase time is changed during the ramp phase, a new ramp rate will be calculated which will achieve the desired phase time. the profile phase timer will stop while the unit is paused or during an error delay caused by profile error band operation (guaranteed soak). profile cycle count remaining (40069/40077) : indicates the number of profile cycles that are yet to be run. if the profile cycle count register (40326/40426) is set to 250, the profile cycle count remaining register will run continuously, resetting to "250" when reaching "0". this register value can be changed, however, it will only affect the current run cycle. when the profile is stopped and re-started, the profile cycle count remaining register will be reloaded based on the "profile cycle count (40326/40426)" value. advance profile phase (40070/40078) : writing a "1" to this register while the profile is running will cause the controller to advance immediately to the beginning of the next ramp or hold phase. using the advance operation shortens the total run time of the profile. if the profile is "paused," the profile will advance but the profile will remain paused. the profile can also be advanced while in the error delay mode. step 12 programming the outputs cycle time (40116/40216) : the cycle time, entered in seconds, is the combined time of an on and off cycle of a time proportioning control output op1/op2. with time proportional output, the percentage of control power is converted into output on time of the cycle time value. (if the controller calculates that 65% power is required and has a cycle time of 10 seconds, the output will be on for 6.5 seconds and off for 3.5 seconds.) for best control, a cycle time equal to one-tenth of the process time constant, or less, is recommended. when using the dc analog output signal for control, a setting of zero will keep output op1 off. the status of op1 can be read through registers 40014/40030. control action (40117/40217) : this determines the control action for the pid loop. programmed for direct action (cooling), the dlc output power will increase if the process value is above the setpoint value. programmed for reverse action (heating), the output power decreases when the process value is above the setpoint value. for heat and cool applications, this is typically set to reverse. this allows op1 to be used for heating, and al2/op2 to be used for cooling. power low limit (40118/40218) ; high limit (40119/40219) : these parameters may be used to limit controller power due to process disturbances or setpoint changes. enter the safe output power limits for the process. if alarm 2 is selected for cooling, the range is from -100 to +100%. at 0%, both op1 and op2 are off; at 100%, op1 is on; and at -100%, op2 is on. when the controller is in manual control mode, these limits do not apply. sensor fail power preset (40120/40220) : this parameter sets the power level for the control outputs in the event of a sensor failure or extreme overdriven/underdriven input. if alarm 2 is not selected for cooling, the range is from 0% (op1 output full off) to 100% (op1 output full on). if al2 is selected for cooling, the range is from -100 to +100%. at 0%, both op1 and op2 are off; at 100%, op1 is on; and at -100%, op2 is on. the alarm outputs are upscale drive with an open sensor, and downscale drive with a shorted sensor (rtd only), independent of this setting. manual control overrides the sensor fail preset. dampening time (40121/40221) : the dampening time, entered as a time constant in seconds, dampens (filters) the calculated output power. increasing the value increases the dampening effect. generally, dampening times in the range of one-twentieth to one-fiftieth of the controllers integral time (or process time constant) is effective. dampening times longer than these may cause controller instability due to the added lag effect. on/off control hysteresis (40122/40222) : the controller can be placed in the on/off control mode by setting the proportional band to 0.0%. the on/off control hysteresis (balanced around the setpoint) eliminates output chatter. in heat/cool applications, the control hysteresis value affects both output op1 and output op2 control. it is suggested to set the hysteresis band to 2 (factory setting) prior to starting auto-tune. after auto- tune, the hysteresis band has no effect on pid control. on/off control hysteresis is illustrated in the the on/off control mode section.
12 step 13 programming the alarms alarm 1 and 2 : the controller is equipped with two alarms for each channel. the status of these alarms can be read through al1 registers 40015/40031 and al2 registers 40016/40032. action (40131/40231), (40136/40236) : select the action for the alarms. see alarm action figures for a visual explanation. manual : in manual mode, the alarms are forced on and off by writing 0 or 1 to the appropriate alarm output register. in this mode, the alarms will not respond to alarm and hysteresis values. absolute hi (balanced or unbalanced hysteresis): the alarm energizes when the process value exceeds the alarm. absolute lo (balanced or unbalanced hysteresis): the alarm energizes when the process value falls below the alarm. deviation hi, deviation lo, band acting : in these actions, alarm 1 and 2 value tracks the setpoint value. cooling (op2) : for heat/cool applications, select cool for alarm 2. the controller then utilizes the alarm 2 output as the cooling output (op2). if cooling is selected, the remaining alarm 2 parameters are not available. off on al + ?hys al al - ?hys off absolute high acting (balanced hys) hys trigger points alarm state off on al + ?hys al al - ?hys off absolute low acting (balanced hys) trigger points hys alarm state alarm state off on hys sp + al sp off trigger points deviation high acting (al > 0) alarm state hys sp - al sp sp + al hys trigger points on off off on on band inside acting alarm state offo n hys sp - al sp off trigger point s deviation low acting (al > 0) alarm state off on hys al al - hys off trigger points absolute high acting (unbalanced hys) alarm state off on hys al + hys al off trigger points absolute low acting (unbalanced hys) alarm state on off hys sp + (-al) sp on trigger points deviation high acting (al< 0) alarm state on hys sp - al sp off sp + al on hys off off trigger points band outside actin g alarm action figures note : hys in the above figures refers to the alarm hysteresis. value (40003/40019), (40004/40020) : the alarm values are entered as process units or degrees. hysteresis (40134/40234), (40139/40239) : the hysteresis value is either added to or subtracted from the alarm value, depending on the alarm action selected. see the alarm action figures for a visual explanation of how alarm actions are affected by the hysteresis. trigger points : trigger points are the process values where the alarm state changes. their values cannot be entered directly, but are shown as a reference in the sfdlc software. the alarm value, hysteresis value, and setpoint alarm type determine the trigger points. with deviation or band actions, the alarm value and setpoint value are combined to determine the trigger points. trigger points must not be greater than +32000 or less than -32000. if these limits are exceeded, the alarm may not function properly. reset (40132/40232), (40137/40237) : the alarms can be programmed for automatic or latched. in automatic mode, an energized alarm turns off automatically once the process value leaves the alarm region. in latched mode, an energized alarm requires a manual reset. this is done by writing 0 to the appropriate output status register. after writing 0, the automatic or latched alarm will not turn on again until after the process value first returns to the alarm off region. only alarms configured for manual action can be energized by writing a 1 to its alarm output status register. on delay (40135/40235), (40140/40240) : the time, in seconds, required for the process value to be in the alarm region before the alarm will activate. it is used to allow temporary or short excursions into the alarm region without tripping the alarm. enable standby delay (40133/40233), (40138/40238) : standby prevents nuisance (typically low level) alarms after a power up or setpoint change. after powering up the controller or changing the setpoint, the process must leave the alarm region. once this has occurred, the standby is disabled and the alarm responds normally until the next controller power up or setpoint change.

14 step 16 programming the dlc comms port note: if the software selectable communication settings are changed and then a download is performed, the controller will immediately respond to the new settings. any further attempts to communicate to the controller must target the new address, with the new settings. serial settings modbus protocol (40405) : rtu or ascii unit address (40401) : 1-247 baud rate (40402) : 300 to 38400 data bits (40404) : 7 or 8 parity (40403) : odd, even, or none transmit delay (40406) : programmable from 2-250 milliseconds. the transmit delay is the time the dlc waits to respond to a serial command, unless the values in the table are larger. note : changing the above parameters by writing to their registers directly will not update the dlc until load serial settings register 40407 is a 1. after a write, this register will return to 0. dip switch serial settings: the dip switches can be used to select the baud rate, parity, and unit address. when using the dip switches to configure the serial settings, the modbus communications mode will be rtu only. there is also a "default serial settings" switch to quickly configure the dlc for use with the "rlcpro" programming software. software selectable serial settings : setting all of the dip switches to the "off" position and having the "default serial setting" terminal un-connected, enables software selectable serial settings. when leaving the factory the software selectable serial settings are set to the serial communication defaults. software selectable serial settings allows set-up of all serial settings including the choice of rtu or acsii communications modes and the number of data bits. if the software selectable serial settings are changed, the load serial register must be used or power to the dlc must be removed and re-applied in order for the settings to take effect. the use of rlcpro programming software or another software program supporting modbus protocol is required to write to the dlc serial settings registers (40401-40407) . step 15 programming the analog output (optional) note: the register numbers correspond to (analog output 1/output 2). assignment (40301/40309) : this setting selects the value that the analog output will retransmit, or track. the analog output can be assigned for the following: mode (40302/40310) : select the type of output and range. the analog output jumpers must be set to match the output type and range selected. the analog output can be calibrated to provide up to 5% of over range operation. output scaling values : the scaling low value (40303/40311) corresponds to 0 v, 0 ma or 4 ma, depending on the range selected. the scaling high value (40304/40312) corresponds to 10 v or 20 ma depending on the range selected. an inverse acting output can be achieved by reversing the scaling low and scaling high points. deadband (40305/40313) : the output power change must be greater than the deadband value in order for the analog output to update. this only applies when the analog output is assigned to output power. this setting can be used to reduce actuator activity. update time (40306/40314) : to reduce excess valve actuator or pen recorder activity, the update time of the analog output can be set in seconds. a value of zero seconds results in an update time of 0.1 second. direct entry value (40307/40315) : if the analog output is programmed for direct entry, it retransmits this value. this value may be controlled by the host. filter (40308-40316): entering a 1 will apply averaging when the update time >=1. selection description output power a process value a retransmits process value channel a setpoint a retransmits setpoint value channel a ramping setpoint a retransmits ramping setpoint channel a deviation a retransmits deviation (difference of setpoint value - process value) channel a direct entry value 1 retransmits direct entry value 1 (manual analog control) output power b transmits the output power demand of channel b. used if linear control is desired. process value b retransmits process value channel b setpoint b retransmits setpoint value channel b ramping setpoint b retransmits ramping setpoint channel b deviation b retransmits deviation (difference of setpoint value - process value) channel b direct entry value 2 retransmits direct entry value 2 (manual analog control) transmits the output power demand of channel a. used if linear control is desired. minimum transmit delay baud rtu ascii 38400 2 msec 2 msec 19200 3 msec 2 msec 9600 5 msec 2.3 msec 4800 9 msec 4.6 msec 2400 17 msec 9.2 msec 1200 33 msec 18.4 msec 600 65 msec 36.7 msec 300 129 msec 73.4 msec
15 default serial settings : the dlc serial port can be temporarily set to the factory defaults by setting the default serial communications dip switch to the up position or by placing a jumper from the default serial setting terminal 7 (tbb) to output common terminal 4 (tba). both of these have precedence over the dip switch serial settings and the software selectable serial settings. once the serial default dip switch is set to the off position or the jumper is removed, the dlc serial settings will immediately change as programmed by the dip switches or the software selectable serial settings if all of the dip switches are in the off position. the default serial settings are not loaded into the software selectable serial registers when the serial default setting switch/terminal is active, they must be explicitly changed. serial communication defaults: 9600 baud, 1 start bit, no parity, 1 stop bit, address 247, and rtu mode. communications diagnostics : the communications diagnostics function (modbus function code 08) can be used to troubleshoot systems that are experiencing communication errors. press the read button to retrieve the diagnostics information. the commands received and the commands processed values are automatically reset when the values are read, at each controller power-up, and when the commands received reaches 65536. commands received : the total number of messages received that started with the controllers own address since the last reset or power up. commands processed : the number of good messages received. a good message is considered one that contained the correct unit address, parity, and checksum (crc or lrc). step 17 pc port configuration go to the settings pull-down menu, and select pc port settings. the communications settings window allows you to set up the software properly to perform a download. connection : select the computer port (comm 1-4) that the dlc is connected to. note : the following settings must match the dlc. if you do not know or cannot recall the dlc settings, they can be temporarily set to factory defaults. simply jumper the default serial setting terminal 7 to input common terminal 4 or put the default serial settings dip switch in the up position. the serial settings will default to rtu mode, 9600 baud, 8 data bits, no parity, with an address of 247. protocol : rtu or ascii unit address : 1-247 baud rate : 300, 600, 1200, 2400, 4800, 9600, 19200, 38400 data bits : 7 or 8 parity : odd, even, or none both flashing all flashing = checksum error input error rs485 modbus protocol ch b alm = pwr/comm. input error both flashing ch a alm autotune ch b op ch a op = cbpro dlc model dlc red lion controls note: the cbpro007 download cable does not typically require power. in most cases it will derive its power from the pc. if communications can not be established, follow the troubleshooting guide. if it is determined that the converter requires power, attach a 12 vdc power supply to the vdc and common terminals of the cable. connect the dlc to the computer with the cbpro007 interface cable (or any suitable rs232/rs485 converter). apply power to the supply terminals of the dlc. step 18 downloading go to the file pull-down menu, and select download. the following screen prompts you to ensure that the proper file is downloaded to the correct controller. click ok to continue.
16 step 19 scratch pad memory the scratch pad category can be used to read or write to the scratch pad memory locations (41101- 41116). the scratch pad locations can be used to store user information. data format : allows registers to be viewed in decimal or hexadecimal format. upload : the upload button causes sfdlc software to read the scratch pad registers from the controller. download : the download button causes sfdlc software to write to the scratch pad registers in the controller. note: downloading new values to the controller scratch pad locations overwrites the information that is currently stored in those registers. defaults : for this category, there are no controller factory defaults. the defaults for this category are only sfdlc software basic default values. step 20 view registers the view registers category can be used as a method of diagnostics. use the dlc register table as a reference of register assignments and data. first register : this specifies the first register to be read in a block. # of registers : this is the length of the block to be read. the controller supports block read and write commands up to 32 registers in length. the sfdlc software only allows 16 to be read in a block. data format : allows registers to be viewed in decimal or hexadecimal format. read : clicking the read button causes sfdlc software to read the selected registers from the controller. write : clicking the write button causes sfdlc software to write the selected registers to the controller. note: the write button overwrites the existing register values, and may change the module setup and operation. defaults : for this category, there are no controller factory defaults. by clicking defaults, the present entries from the other sfdlc software category screens will be displayed. step 21 calibration the dlc is fully calibrated from the factory. recalibration is recommended every two years. each channel is calibrated separately. all calibration settings are stored in the non-volatile memory. calibration may be performed by using sfdlc software or modbus commands. when using sfdlc for calibration, connect the signal or measuring source to the proper dlc terminals, verify the input or output jumper positions, select the type of calibration to be performed, and click the calibrate button. follow the calibration procedures in the software. note : allow the dlc to warm up for 30 minutes minimum and follow the manufacturers warm-up recommendations for the calibration source. input calibration when calibrating the input, the millivolt calibration must be performed first. all other input types use the millivolt points. each input range (non-thermocouple) also has its own internal references that are recalled when the range is selected. non-used types need not be calibrated. calibration type : this specifies the type of calibration to be performed. millivolt : millivolt calibration requires a precision voltage source with an accuracy of 0.03% or better. it is used for thermocouple inputs and as a basis for all other input calibration types. rtd : rtd calibration requires a 0.1% (or better) precision 277.0 ohm resistor. process voltage : process calibration requires a precision signal source with an accuracy of 0.03% (or better) that is capable of generating 10.00 v. process current : process current calibration requires a precision signal source with an accuracy of 0.03% (or better) that is capable of generating 20.00 ma. cold junction : cold junction calibration requires a thermocouple of known accuracy of types t, e, j, k, c or n only and a calibrated external reference thermocouple probe. tc type : this selects the type of tc that is being used to calibrate the cold junction. scale : this selects the scale in which the thermometer temperature is entered and the controller temperature is displayed. thermometer : enter the reference thermometer temperature here. dlc : this displays the dlc process temperature value after a cold junction calibration is completed to verify the accuracy. calibrate : the calibrate button initiates the calibration process after the appropriate settings are selected.
17 analog output calibration calibration type : this specifies the analog output point to be calibrated. volts : analog output voltage calibration requires a precision meter with an accuracy of 0.05% (or better) that is capable of measuring 10.00 v. ma : analog output current calibration requires a precision meter with an accuracy of 0.05% (or better) that is capable of measuring 20.00 ma. meter value: after pressing the calibrate button, this shows the value the dlc is outputting. measure the actual output with an external meter and enter that value here. press the calibrate button again and follow the prompts. calibrate : the calibrate button initiates the calibration process after the appropriate settings are selected. application a plastic extrusion company was building a four-zone extruder, and wanted a centrally located, multi-zone interface. the interface needed to display the temperature and setpoint values, as well as the screw rpm and barrel pressure. the customer provided a speed proportional 0-10 volt signal from a motor drive, and installed a 4-20 ma output pressure sensor in the extruder barrel. each of the four heat/cool zones were equipped with a thermocouple. three dlc-dual loop controllers, with a g3 hmi, allowed the customer to build his own control system. only three dlcs were required; two were needed to control the four temperature zones, and one was needed to monitor the two process signals. all three units were connected to the rs485 port of the g3 display. the customer created his own displays on the hmi, which allowed him to monitor and control the setpoints and alarms within the dlcs. the g3s multi-protocol capability allowed it to tie the dlcs to his plc, creating a true centralized interface. control mode explanations manual control mode in manual control mode, the controller operates as an open loop system (does not use the setpoint and process feedback). the user enters a percentage of power through the output power register (40005/40021) to control the heat (reverse) or cool (direct) for output op1. when alarm 2 is configured for cooling (op2), manual operation provides 0 to 100% power to op1 (heating) and -100 to 0% power to op2 (cooling). the low and high power limits are ignored when the controller is in manual. for time proportional outputs, the output power is converted into output on time using the cycle time. for example, with a four second cycle time and 75% power, the output will be on (4 0.75) for three seconds and off for one second. for analog outputs (0-10 vdc or 0/4-20 ma), the percent output power is converted into a linear value according to the percent low and high scaling set for the analog output. for example, with 0 vdc (scaled 0.0%) to 10 vdc (scaled 100%) and 75% power, the analog output will be 7.5 vdc. mode transfer when transferring the controller mode from or to automatic, the controlling outputs remain constant, exercising true bumpless transfer. when transferring from manual to automatic, the power initially remains steady, but integral action corrects (if necessary) the closed loop power demand at a rate proportional to the integral time. the control mode can be changed through the control mode register (40041/40049). automatic control mode in automatic control mode, the percentage of output power is automatically determined by pid or on/off calculations based on the setpoint and process feedback. for this reason, pid control and on/off control always imply automatic control mode. protocol modbus rs485 rs485 protocol modbus rs485 modbus protocol zone 4 zone 3 four-zone extruder power 18-36vdc / 24vac 0-10v sig. 4-20ma sig.

18 on/off control the controller operates in on/off control when the proportional band is set to 0.0%. in this control, the process will constantly oscillate around the setpoint value. the on/off control hysteresis (balanced around the setpoint) can be used to eliminate output chatter. output op1 control action can be set to reverse for heating (output on when below the setpoint) or direct for cooling (output on when above the setpoint) applications. on/off control - reverse or direct acting figures for heat and cool systems, op1 control action is set to reverse (heat) and the alarm 2 action is set to cooling (op2). the proportional band is set to 0.0 and the relative gain in cooling to 0.0. the deadband in cooling sets the amount of operational deadband or overlap between the outputs. the setpoint and the on/off control hysteresis applies to both op1 and op2 outputs. the hysteresis is balanced in relationship to the setpoint and deadband value. on/off control - heat/cool output figures off output 1 (op1) : off sp on input reverse acting sp+1/2 hys sp-1/2 hys off output 1 (op1) : sp off input direct acting sp-1/2 hys sp+1/2 hys on on output 2 (op2) : on sp off input heat/cool deadband value (db) = 0 sp + 1/2 hys sp - 1/2 hys off off output 1 (op1) : on hys sp sp + 1/2 (db) - 1/2 hys sp + 1/2 (db) + 1/2 hys sp - 1/2 (db) + 1/2 hys sp - 1/2 (db) - 1/2 hys hea t/cool deadband va lue (db) < 0 db hys hys on off off on output 1 (op1) : output 2 (op2) : on on input sp + 1/2 (db) sp - 1/2 (db) db output 1 (op1) : output 2 (op2) : sp - 1/2 (db) + 1/2 hys sp - 1/2 (db) - 1/2 hys off sp on off off on hys off hea t/cool deadband va lue (db) > 0 sp + 1/2 (db) - 1/2 hys sp + 1/2 (db) + 1/2 hys hys input sp + 1/2 (db) sp - 1/2 (db) pid control in pid control, the controller processes the input and then calculates a control output power value by use of a modified proportional band, integral time, and derivative time control algorithm. the system is controlled with the new output power value to keep the process at the setpoint. the control action for pid control can be set to reverse for heating (output on when below the setpoint) or direct for cooling (output on when above the setpoint) applications. for heat and cool systems, the heat (op1) and cool (op2) outputs can be used together in the pid control. the pid parameters can be auto-tune or manual tune to the process. typical pid response curve sp time p & i p & i & d p only p & d input remote setpoint channel b can operate as a remote setpoint input to channel a. channel b pid control is not functional when the input is assigned as a remote setpoint. this mode of operation enables cascade control (external), ratio control, and temperature setpoint slave control, among others. the remote setpoint value used internally by the controller is: remote setpoint = (scaled chb input * remote setpoint ratio multiplier) + remote setpoint bias offset where ratio multiplier = 0.0001 to 3.2000 bias offset = -32000 to 32000 the ratio multiplier and bias offset parameters offer on-line scaling of the remote setpoint to adjust control ratios or biases among related processes. the remote setpoint is restricted to the setpoint low and high limit values for channel b. these parameters may be used to limit the range of the remote setpoint to a safe or more stable control range. for remote setpoint signal sources that change wildly or are too sensitive to process upsets, the cha setpoint ramp rate parameter (40110) can be used to ramp (rate limit) the remote setpoint reading. this can subsequently reduce the fluctuations of the secondary control loop. note: hys in the on/off control figures refers to the on/off control hysteresis.
19 auto-tune auto-tune is a user-initiated function where the controller automatically determines the proportional band, integral time, derivative time, digital filter, control ouput dampening time, and relative gain (heat/cool) values based upon the process characteristics. the auto-tune operation cycles the controlling output(s) at a control point three-quarters of the distance between the present process value and the setpoint. the nature of these oscillations determines the settings for the controllers parameters. prior to initiating auto-tune, it is important that the controller and system be first tested. (this can be accomplished in on/off control or manual control mode.) if there is a wiring, system or controller problem, auto-tune may give incorrect tuning or may never finish. auto-tune may be initiated at start-up, from setpoint or at any other process point. however, insure normal process conditions (example: minimize unusual external load disturbances) as they will have an effect on the pid calculations. auto-tune cannot be initiated while running a profile. time input typical response curves with auto-tune codes 0 to 2. sp 0 1 2 auto-tune code figure pid tuning explanations start auto-tune 1. enter the on/off control hysteresis value.

20 manual tuning a chart recorder or data logging device is necessary to measure the time between process cycles. this procedure is an alternative to the controllers auto-tune function. it will not provide acceptable results if system problems exist. this procedure should be performed by directly accessing the controllers registers. the register numbers correspond to (channel a/channel b). 1. set the proportional band (40007/40023) to 10.0% for temperature inputs and 100.0% for process inputs. 2. set both the integral time (40008/40024) and derivative time (40009/40025) to 0 seconds. 3. set the output dampening time (40121/40221) to 0 seconds. 4. set the output cycle time (40116/40216) to no higher than one-tenth of the process time constant (when applicable). 5. place the controller in manual control mode (40041/40049) and adjust the output power (40005/40021) to drive the process value to the setpoint value. allow the process to stabilize after setting the output power. 6. place the controller in automatic control mode (40041/40049). if the process will not stabilize and starts to oscillate, set the proportional band two times higher and go back to step 5. 7. if the process is stable, decrease proportional band setting by two times and change the setpoint value a small amount to excite the process. continue with this step until the process oscillates in a continuous nature. 8. fix the proportional band to three times the setting that caused the oscillation in step 7. 9. set the integral time to two times the period of the oscillation. 10. set the derivative time to one-eighth (0.125) of the integral time. 11. set the output dampening time to one-fortieth (0.025) the period of the oscillation. modbus information the remaining sections of this bulletin list
