E5AK v f if you remove the controller from its case, never touch nor apply shock to the electronic parts inside. f do not cover the area around the E5AK. (ensure sufficient space around the controller to allow heat radiation.) f use a voltage (ac100-240v or ac/dc24v at 50 to 60 hz). at power on, the pre- scribed voltage level must be attained within two seconds. f when wiring input or output lines to your controller, keep the following points in mind to reduce the influence from inductive noise: allow adequate space between the high voltage/current power lines and the input/out- put lines. avoid parallel or common wiring with high voltage sources and power lines carrying large currents. using separating pipes, duct, and shielded line is also useful in protecting the controller, and its lines form inductive noise. f allow as much space as possible between the controller and devices that generate a pow- erful, high frequency (high-frequency welders, high-frequency sewing machines, and so forth) or surge. these devices may cause malfunctions. f if there is a large power-generating peripheral device and any of its lines, attach a surge suppressor or noise filter to the device to stop the noise affecting the controller system. in particular, motors, transformers, solenoids and magnetic coils have an inductance component, and therefore can generate very strong noises. f when mounting a noise filter, be sure to first check the filter?s voltage and current capacity, then mount the filter as close as possible to the controller. f do not use the controller in places where icing, condensation, dust, corrosive gas (espe- cially sulfurized gas or ammonia gas), shock, vibration, splashing liquid, or oil atmo- sphere occur. also, avoid places where the controller can be subjected to intense heat radiation (like from a furnace) or sudden temperature changes. f ambient temperature must be kept between -10 _ cto55 _ c. ambient humidity must be kept between 35%rh to 85%rh (with no icing or condensation). if the controller is installed inside a control board, the ambient temperature must be kept under 55 _ c, including the temperature around the controller. if the controller is subjected to heat radiation, use a fan to cool the surface of the controller to under 55 _ c. f store the controller at an ambient temperature between -25 _ cto65 _ c. the ambient humidity must be between 35%rh to 85%rh (with no icing or condensation). f never place heavy objects on, or apply pressure to the controller that may cause it to deform and deterioration during use or storage. f avoid using the controller in places near a radio, television set, or wireless installation. these devices can cause radio disturbances which adversely affect the performance of the controller. pay a ttention to the following when installing this controller

chapter 1 introduction E5AK 1--10 1.4 about the communications function the E5AK can be provided with a communications function that allows you to check and set controller parameters from a host computer. if the communications function is required, add on the communications unit. for details on the communications function, refer to chapter 6. when using the communications function on the rs-232c interface, add on the communications unit (e53-ak01). when using the communications function on the rs-422 interface, add on the communications unit (e53-ak02). when using the communications function on the rs-485 interface, add on the communications unit (e53-ak03). f rs-232c f rs-422 f rs-485
1.1 names of parts E5AK 1--11 1.5 about calibration the E5AK controller is calibrated before shipment from the factory. so, the user need not calibrate the E5AK controller during regular use. however, if the E5AK controller must be calibrated by the user, use the parameters provided for user to calibrate temperature input, analog input (voltage, current) and transfer output. also, note that calibration data is updated to the latest value each time the E5AK controller is calibrated. calibration data set before shipment from the factory cannot be returned to after calibration by the user. the input type selected in the parameter is the item to be calibrated. the E5AK is provided with the following four calibration parameters. thermocouple platinum resistance thermometer current input voltage input two parameters are provided for thermocouple and voltage input. transfer output can be calibrated when the communications unit (e53-akf) is added on. when calibrating each item, the calibration data is temporarily regis- tered. this data can be registered as final calibration data only when all items have been newly calibrated. so, all items must be temporarily regis- tered when calibrating the E5AK controller. when registering data, information regarding whether or not calibration has been carried out is also registered. to calibrate these items, the user must prepare separate measuring devices and equipment. for details on handling these measuring devices and equipment, refer to the respective manuals. for details, see chapter 7 calibration. f calibrating inputs f calibrating trans- fer output f registering cal- ibration data

3.3 setting output specifications E5AK 3--7 factory settings are as follows: control output 1 = control output (heat) control output 2 = alarm 1 auxiliary output 1 = alarm 2 auxiliary output 2 = alarm 3. output assignments are set in the ?control output 1 assignment?, ?con- trol output 2 assignment?, ?aux output 1 assignment? and ?aux output 2 assignment? parameters (setup mode). position-proportional type controllers support six output functions. these are assigned to auxiliary outputs 1 and 2. restrictions on assignment destinations are placed on some of the out- puts. the following table shows where outputs may be assigned to. assignment d e s t i n a t i o n control output auxiliary output d es t i na t i on output function 1 2 1 2 alarm 1 f f alarm 2 f f alarm 3 f f error 1 : input error f f error 2 : a/d converter error f f error 3 : rsp input error f f ?direct operation? (or normal operation) refers to control where the manipulated variable is increased according to the increase in the pro- cess value. alternatively, ?reverse operation? refers to control where the manipulated variable is decreased according to the decrease in the pro- cess value. for example, when the process value (pv), is lower than the set point (sp), in a heating control system, the manipulated variable increases by the difference between the pv and sp values. accordingly, this becomes ?reverse operation? in a heating control system. alternatively, this becomes ?direct operation? in a cooling control system. direct/reverse operation is set in the [ ]?direct/reverse operation? parameter (setup mode). when the output unit is pulse output such as relay output, set the pulse output cycle (control period). though a shorter pulse period provides better control performance, the control period should be set taking the life expectancy of the output unit into consideration when the output unit is relay. the control period is set in the ?control period (heat)? parameter (level 1 mode). factory setting is ?20:20 seconds.? the ?control period (cool)? output function is not allocated. so, the ?control period (cool)? parameter cannot be set. f position-propor- tional type j direct/reverse operation j control period

4.2 operating condition restrictions E5AK 4--5 4.2 operating condition restrictions the upper-and lower-limit values of the manipulated variable can be restricted by the mv limiter, and the change rate of the manipulated vari- able can be restricted by the mv change rate limiter. the upper-and lower-limit values of the manipulated variable are set in the ?mv upper limit? and ?mv lower limit? parameters (level 2 mode). when the manipulated variable calculated by the E5AK is outside of the range of the mv limiter, actual outputs are dependent on the set value of these parameters. 100 0 pv output (%) mv upper limit value mv lower limit value in heating and cooling control, the manipulated variable at the cooling side is treated as a negative value for the sake of convenience. the upper limit is set for the heating side (positive value), and the lower limit is set for the cooling side (negative value) as shown in the following figure. 100 0 pv output (%) mv upper limit value mv lower limit value heating side set point cooling side the ?mv change rate limit? parameter (level 2 mode) sets the maximum permissible change width per second of the manipulated variable. if a change in the manipulated variable exceeds this parameter setting, the value calculated by the E5AK is reached while changing the value by the per-second value set in this parameter. 100 0 output (%) switching point time mv change rate limit value 1 second j manipulated vari- able restrictions f mv limiter f mv change rate limiter

4.5 how to use the heater burnout alarm E5AK 4--13 4.5 how to use the heater burnout alarm on a standard type controller, the hba (heater burnout alarm) function can be used only when the assignment destination of the output function ?control output (heat)? is set to pulsed output. when using the hba function, assign output function ?heater burnout (hb) alarm? to auxiliary outputs 1 or 2. heater burnout detection works as follows. (1) connect the current transformer (ct) to terminal nos.15 and 17, and insert the heater lead through the ct hole. (2) when current flows through this lead, the current transformer gener- ates ac current proportional to the current value. the E5AK mea- sures this ac current to calculate the current flowing to the heater. (3) if heater is burned out, the current measured at the current trans- former decreases. this value is compared with the value set as the heater burnout set value and is output as the heater burnout alarm. set the heater burnout set value in the ?heater burnout alarm? parame- ter. to check the current value of the current transformer, use the ?heater current monitor? parameter. when you are not using the hba function, set the ?heater burnout alarm? parameter to ?0.0 (disabled)?. when the hba latch function is set to ?on?, the heater burnout alarm is held until either of the following measures is taken: a set the heater burnout set value to ?0.0?. b reset the controller. (turn the controller?s pow er off then back on again.) to enable the hba latch function, set the ?hba latch? parameter to ?on?. turn the heater power supply on at the same time as or before turning the E5AK power supply on. if the heater power supply is turned on after turning the E5AK power supply on, the heater burnout alarm is output. control is continued even when the heater burnout alarm is output. (that is, the controller attempts to control the heater as if the heater burnout alarm has not occurred.) so, remedy the condition such as repairs which are caused by the heater burnout alarm. the heater burnout alarm is detected only if the control output is contin- uously on for 190 ms or more. the rated current value may sometimes differ slightly from the actual current value flowing to the heater. check the current value in an actual operating status in the ?heater current monitor? parameter. if there is little difference between the current in a normal status and the current in a burnout status, detection may become unstable. on a heater of current 10.0 a or less, maintain a difference of 1.0 a or more. on a heater of current 10.0 a or more, maintain a difference of 2.5 a or more. heater burnout alarm function cannot be used when controlling the heater by a phase control method or by a cycle control method. also, 3-phaseheaterscannotbeused. when detecting heater burnout on a 3-phase heater, use the k2cu-f vv a- v gs (with gate input terminal).

chapter 4 applied operation E5AK 4--14 calculate the set value nby the following formule: set value = (current value at normal operation + current value at burnout) 2 set the current value at burnout when two or more heaters are con- nected to the ct to the value at the time that the heater having the small- est current value burns out (the value when one of the heaters burns out with all heaters at the same current). make sure that the following condition is satisfied: heater of current 10.0 a or less current value at normal operation --- current value at heater burn- out R 1a when resultant current is less than 1 a, detection is unstable. heater of current 10.0 a or more current value at normal operation --- current value at heater burn- out R 2.5 a when resultant current is less than 2.5 a, detection is unstable. the setting range is 0.1 to 49.9 a. heater burnout is not detected when the setting is ?0.0? or ?50.0?. when the setting is ?0.0?, the heater burn- out alarm is set to ?off?, and when the setting is ?50.0?, the heater burnout alarm is set to ?on?. set the total current value at normal heater operation to 50 a or less. when set to 55.0 a or more, [ ] is displayed in the ?heater current monitor? parameter. example 1 : when using a 200 vac, 1 kw heater current at normal operation = 1000 200 =5a( < 10a) current at heater burnout = 0a set value = 5+0 2 =2.5a example 2 : when using three 200 vac, 1 kw heaters set value = current at normal operation = 1000 200 3 = 15a ( R 10a) current at burnout of one heater = 1000 200 2 = 10a 15+10 2 = 12.5a (current at normal operation ---current at heater burnout =15---10=5a( R 2.5a) symbol parameter name: mode application heater current monitor : level 1 heater current value monitor heater burnout : level 1 heater burnout detection heater burnout latch : option heater burnout detection alarm latch j how to calculate the heater burn- out set value f examples of use 15 control output 17 heater 1kw ac200v ct E5AK 15 control output 17 heater 1kwx3 ac200v ct E5AK parameters
4.6 lba E5AK 4--15 4.6 lba the lba (loop break alarm) function can be used only on standard type controllers. the lba function can be used only when assigned as an output. also, the lba function does not work when a memory error or a/d converter error results. lba (loop break alarm) is a function for judging that an error has occurred somewhere on the control loop and outputting an alarm when the process value does not change with the manipulated variable at a maximum or minimum state. accordingly, the lba function can be used as a means for detecting a malfunctioning control loop. normally, when output is set to maximum or minimum, the process value rises or falls after the dead time has elapsed. lba is output if the process value does not change in the predicted direction after a fixed amount of time has elapsed. this fixed amount of time is the ?lba detec- tion time.? lba operation sometimes becomes unstable when the process value fluctuates considerably due to the control characteristics. the lba detection width is provided so that changes with respect to output can be correctly detected. changes smaller than the detection width due to lba detection timing are not regarded as changes. the following example describes what happens when a heater burnout at maximum output. pv lba=on lba detection time lba detection width output time heater burnout lba detection time lba judgment is carried out at each lba detection time from the point of maximum output. in above figure, the process value (pv) is changing greatly at the 1st judgment timing, so lba remains off. at the 2nd judgment timing, the process value increases as indicated by the broken line of the process value is normal. this means that the change width exceeds the lba detection width, and lba output remains off. if the heater burns out at the point shown in the above figure, the process value ?decreases.? accordingly, it is judged that ?the process value is not changing in the increasing direction? at the 2nd judgment timing and the lba output becomes on. f lba detection time f lba detection width f lba detection example
chapter 4 applied operation E5AK 4--16 the lba detection time is automatically set by auto-tuning (except in heating and cooling control). if the optimum lba detection time cannot be obtained by auto-tuning, set the time in the ? lba detection time? parameter (level 2 mode). calculate the lba detection time as follows: (1) set output to maximum. (2) measurethetimeittakesfortheinputchangewidthtoreachthelba detection width (default: 0.2 % full-scale). (3) take a value twice that of the measurement time as the lba detection time. pv 0.2%fs measurement time tm lba detection time = tm x 2 output time (4) in the case of on/off operation, set the lba detection time to a val- ue longer than the control period. symbol parameter name: mode application at execute/cancel : level 1 automatic setting of lba detec- tion time lba detection time : level 2 setting of lba detection time lba detection width : expansion changing of lba detection width f setting the lba detection time f determining the lba detection time parameters

chapter 8 troubleshooting E5AK 8--1 chapter 8 troubleshooting this chapter describes how to find out and remedy the cause if the E5AK does not function properly. chapter 8 8.1 initial checks 8-2 .......................... 8.2 how to use the error display 8-3 ........... 8.3 how to use error output 8-5 ............... 8.4 checking operation restrictions 8-6 ........
chapter 8 troubleshooting E5AK 8--2 8.1 initial checks if trouble occurs, first of all check the following. (1) power supply make sure that the power supply is on. also, make sure that the power supply is within the rated voltage range. (2) wiring make sure that all cables are properly connected. (3) communications condition when communicating using the rs-232c, rs-422 or rs-485 commu- nications interfaces, make sure that the baud rate and other commu- nications condition settings on the host computer and E5AK control- ler are matching, and are within the permissible ranges. if there appears to be nothing wrong after checking the E5AK controller, and the same phenomenon continues, check the controller in more detail, forexample,ontheerrordisplay.
8.2 how to use the error display E5AK 8--3 8.2 how to use the error display when an error has occurred, the no.1 display alternately indicates error codes together with the current display item. this section describes how to check error codes on the display, and the actions you must be taken to remedy the problem. input error input is in error. check the wiring of inputs, disconnections, and shorts, and check the in- put type. for control output functions, output the manipulated variable matched to the setting of the ?mv at pv error? parameter (level 2 mode). alarm out- put functions are activated when the upper limit is exceeded. memory error internal memory operation is in error. first, turn the power off then back on again. if the display remains the same, the E5AK controller must be repaired. if the display is restored to normal, then a probable cause can be external noise affecting the control system. check for external noise. control output functions turn off (2ma max. at 4 to 20ma output, and output equivalent to 0% in case of other outputs). alarm output functions turn off. a/d converter error internal circuits are in error. first, turn the power off then back on again. if the display remains the same, the E5AK controller must be repaired. if the display is restored to normal, then a probable cause can be external noise affecting the control system. check for external noise. control output functions turn off (2ma max. at 4 to 20ma output, and output equivalent to 0% in case of other outputs). alarm output functions turn off. f meaning f action f operation at error f meaning f action f operation at error f meaning f action f operation at error
chapter 8 troubleshooting E5AK 8--4 calibration data error this error is output only during temperature input, and is displayed for two seconds when the power is turned on. calibration data is in error. must repair. both control output functions and alarm output functions operate. how- ever, note that readout accuracy is not assured. display range over though not an error, this is displayed when the process value exceeds the display range when the control range (setting range 10%) is larger than the display range (-1999 to 9999). when less than ?-1999? [ ] when greater than ?9999? [ ] control continues, allowing normal operation. motor calibration error (displayed on the no. 2 display) motor calibration has ended with an error. first, correctly connect the wiring for the potentiometer, open output, and close output. execute the motor calibration again. when motor calibration is executed, open output will operate and then close output will operate. however, as the value is incorrect, the result turns out to be an error. f meaning f action f operation at error f meaning f operation f meaning f action f operation proce- dure f operation at error
8.3 how to use error output E5AK 8--5 8.3 how to use error output the E5AK controller allows you to assign error output to terminals as out- puts. for details on output assignments, see 3.3 setting output specifications (page 3-6). lba (loop break alarm) can be used as a means for detecting loop breaks when the control loop is not functioning normally. for details, see page 4-15. lba allows you to detect the following errors: (1) heater burnout (2) output error (contact weld, damaged transistors, etc.) (3)sensorerror(constantinputvalues,etc.) if you use the lba function, set the loop break detection time matched to the control characteristics in the ?lba detection time? parameter (level 2 mode). if you assign error 1 as the output, an error can be output to auxiliary output 1 or auxiliary output 2 when input is in error. when this error occurs, remedy by following the description for ?input error? (page 8-3). if you assign error 2 as the output, an error can be output to auxiliary output 1 or auxiliary output 2 when the a/d converter is in error. when this error occurs, remedy by following the description for ?a/d converter error? (page 8-3). if you assign error 3 as the output, an error can be output to auxiliary output 1 or auxiliary output 2 when the remote sp input error occurs while the remote sp function is enabled. for details on error displays and meanings, see chapter 4 applied operation/4.4 how to use the remote sp (page 4-11). when an error occurs, check the state of the remote sp connection. if the lead is broken or disconnected, the remote sp scaling lower limit is dis- played blinking on the pv/sp display or remote sp monitor display. f lba f input errors f a/d converter error f remote sp input error

appendix E5AK a--14 fuzzy self-tuning fuzzy self-tuning is a function that enables the E5AK to calculate the most suitable pid constants for the controlled object. j features the E5AK determines by itself when to perform fuzzy self-tuning. at the time of fuzzy self-tuning, the E5AK does not output any signal that disturbs the temperature or output value. j fuzzy self--tuning function the fuzzy self-tuning function has three modes. in srt(step response tuning) mode, the pid constants are tuned using a step response method at the time the set point is changed. in dt(disturbance tuning) mode, the pid constants are amended so that the controlled temperature will be within the target range set in advance when there is external disturbance. in ht(hunting tuning) mode, when hunting occurs, the pid constants are amended to suppress the hunting. note: be sure to turn on the power supply to the load either before or si- multaneously with the start of temperature controller operation. dead time will be measured from the time the temperature con- troller starts operating. if a load such as a heater is turned on after the temperature controller is turned on, dead time longer than the actual value will be measured and inappropriate pid constants will be obtained. if an extremely large amount of dead time is measured, the control amount will be set to 0% for a short period of time before being returned to 100%, and the constants will then be returned. retuning is performed only for large amounts of dead time, so be sure to follow the precaution given above when starting operation. srt will start if the following conditions are satisfied simultaneously whentheE5AKisturnedonorthesetpointischanged. at the time the E5AK starts operation at the time set point is changed 1) the set point at the time the E5AK starts operating is different from the set point used at the time srt was last executed (see note). 2) the process value at the time the E5AK starts operating is smaller than the set point in reverse operation and larger than the set point in normal operation. 1) the new set point is different from the set point used at the time srt was executed last (see note). 2) the process value is in stable condi- tion before the set point is changed. 3) a larger set point value is set in reverse operation and a smaller set point is set in normal operation. note: the last srt-executed set point is set to 0 before shipping and when changing from advanced pid control to advanced pid control with fuzzy self-tuning. f startup conditions of srt
fuzzy self-tuning E5AK a--15 if the step control amount is applied before the maximum temperature slope (r) is obtained, srt will not renew any pid constant. if the propor- tional band obtained from the r and l values that were measured before the imposition had been completed is larger than the present proportional band, the pid constants will be renewed because the measured value is in the direction towards the suitable proportional band value, and the set point at that time will be the srt-executed set point. temperature slope (r) stable range time sp f stable temperature status if the temperature is within the stable range for a certain time, it is deemed that the temperature is stable. this time is called stability judgement time. like pid constants, stability judgement time is adjusted with fuzzy self- tuning according to the characteristics of the object to be controlled. fuzzy self-tuning will not be activated if the temperature is stable because the temperature controller deems that temperature control is smooth. stable stable range stable range stable stability judgement time set point shorter than the stability judgement time (set to 15.0 _ c before shipping) f balanced status if the process value is within the stable range for 60s when there is no out- put,it is deemed that the temperature is balanced. f pid constant refreshing conditions
appendix E5AK a--16 f startup conditions of dt (1) dt will start if the temperature that has been stable varies due to ex- ternal disturbance and the deflection of the temperature exceeds the stable range, and then the temperature becomes stable, provided that the number of maximum temperature values is less than four. (2) dt will start if the set point is changed under the condition that srt does not start and the temperature becomes stable, provided that the number of maximum temperature values is less than four. if there are four or more maximum temperature values, ht will start. temperature extreme value 2 sp set point change extreme value 1 time f startup conditions of ht ht will be on when there is hunting with four or more maximum temper- ature values(extreme values) while srt is not being executed. temperature extreme value 2 sp extreme value 4 extreme value 1 time extreme value 3 note: in specific applications where temperature varies periodically due to disturbance, internal parameters need to be adjusted.
