2 optional remote setpoint input (0/4 to 20 ma) allows for cascade control loops, where tighter control is required; and allows for remotely driven setpoint signal from computers or other similar equipment. straightforward end point scaling with independent filtering and local/remote transfer option expand the controllers flexibility. the optional rs485 serial communication interface provides two-way communication between a t48 and other compatible equipment such as a printer, plc, hmi, or a host computer. in multipoint applications (up to thirty- two), the address number of each t48 on the line can be programmed from 0 to 99. data from the t48 can be interrogated or changed, and alarm output(s) may be reset by sending the proper command code via serial communications. pc software, sfcrm, allows for easy configuration of controller parameters. these settings can be saved to disk for later use or used for multi-controller down loading. on-line help is provided within the software. the unit is constructed of a lightweight, high impact plastic case with a tinted front panel. the front panel meets nema 4x/ip65 specifications when properly installed. multiple units can be stacked horizontally or vertically. modern surface-mount technology, extensive testing, plus high immunity to noise interference makes the controller extremely reliable in industrial environments. 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 t48 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. specifications 1. display: dual 4-digit upper temperature display : 0.4" (10.2 mm) high red led lower auxiliary display : 0.3" (7.6 mm) high green led display messages : olol - appears when measurement exceeds + sensor range. ulul - appears when measurement exceeds - sensor range. open - appears when open sensor is detected. shrt - appears when shorted sensor is detected (rtd only) ... - appears when display values exceed + display range. -.. - appears when display values exceed - display range. led status annunciators : %p - lower auxiliary display shows power output in (%). mn - flashing: controller is in manual mode. on: local setpoint (remote setpoint option) off: remote setpoint dv - lower auxiliary display shows deviation (error) from temperature setpoint or shows heater current. o1 - main control output is active. a1 - alarm #1 is active (for a1 option.) . a2 - alarm #2 is active or - cooling output (o2) is active 2. power: ac versions : 85 vac min. to 250 vac max., 50 to 60 hz, 8 va max. dc versions : dc power : 18 to 36 vdc; 7 w ac power : 24 vac 10%; 50 to 60 hz, 9 va 3. controls: four front panel push buttons for modification and setup of controller functions and one external input user for parameter lockout or other functions. 4. memory: nonvolatile e 2 prom retains all programmable parameters and values. 5. main sensor input: sample period : 100 msec response time : less than 300 msec typ., 400 msec max.

4 basic operation the t48 controls a process temperature by measuring the temperature via an input probe, then calculating a control output power value by use of a modified pid control algorithm. the unit controls the system with the new output power value to keep the process temperature at setpoint. the pid control algorithm incorporates features which provide for high control accuracy and low temperature overshoot from process disturbances. front panel features in the normal operating mode, the unit displays the process temperature in the upper display. one of the following parameters can be viewed in the lower display: - setpoint - % power output - temperature deviation - heater current - temperature symbol (f or c) - blank display the user scrolls through these parameters by pressing the d button. if enabled, the control setpoint or power output (manual mode only) can be directly modified in this mode. in the normal operating mode, parameters are selected by use of the p button and modified by use of the up and down buttons. parameters are then entered by the p button, which advances the user to the next parameter. pressing the d button immediately returns the controller to the normal operating mode without changing the currently selected parameter. hardware features a fast 100 msec input sampling rate provides quick controller response to a process disturbance, thus providing excellent temperature control. measurement accuracy of 0.3% of span 1c or better, provides close process control conforming to the desired control setpoint value. the t48 accepts a variety of both thermocouple and rtd temperature probes. an output board contains the main control output, alarm 1 output, alarm 2/cooling output, and/or linear dc output. since the controller is serviceable from the front of the panel, the output board (on some models) may be easily changed or replaced without disturbing the wiring behind the panel. no re-programming is required when changing or replacing the output board for units without the linear dc output option. units with the linear output option require calibration procedure for the new linear output. low-drift, highly stable circuitry ensures years of reliable and accurate temperature control. the recommended two year re-calibration interval is easily accomplished via the programming menu. remote setpoint input the remote setpoint input facilitates the use of a remote signal to drive the controllers setpoint. the remote signal can be scaled independent to that of the controllers range. the controllers response to local/remote setpoint transfers can be programmed. also, the remote signal is filtered by use of an adaptive filter. with this filter, relatively large filtering time constants can be used without suffering from long settling times. the time constant and filter disable band are programmable. additionally, the remote signal can also be velocity limited (or ramped) to slow the controllers response to changes in setpoint. this results in a steady control response with no overshoot. heater current monitor the t48 provides a direct readout of process heater current. this provides valuable information regarding single phase heater system integrity. it is especially useful on extruder and large oven applications where adjacent controllers mask the effect of a failed heater. the heater break alarm senses two types of heater system faults: 1) main control output is on and heater current is below alarm value. this indicates failed heater or failed parts of heater, breaker trip, failed power control device, etc. 2) main control output is off and heater current is above 10% of alarm value. this indicates a failed power control device, wiring fault, etc. linear dc analog outputs the main linear dc output has independent scaling, programmable output update time and filter (damping) time. these parameters permit flexibility in process configuration. the output can be set for 0 to 10 v, 0 to 20 ma or 4 to 20 ma ranges, and can be configured for control or for transmission of temperature or setpoint values. a second linear dc output is dedicated for retransmission of input temperature. the output can be scaled and converted independent of the input and main linear dc output. this output is isolated from the input. setpoint features the controller setpoint can be protected from out of range values by programming the setpoint range limit values. additionally, safeguards from inadvertent data entry can be programmed. a second setpoint value can be programmed which can be made active by a user input and/or through the front panel on selected models. the setpoint ramp feature ramps the setpoint value at start-up or any time a setpoint change is made, at a user programmable rate. this feature reduces thermal shock to the process and helps to minimize temperature overshoot. input features a programmable input filter can be used to stabilize readings from a process with varying or oscillating temperature characteristics, helping to provide better temperature control. a programmable temperature shift function can be used to compensate for probe errors or to have multiple t48 units indicate the same nominal temperature. the programmable user input can be used to control a variety of functions, such as auto/manual transfer of the controller, reset alarm output (s) , transfer to second setpoint, etc. output features programmable output power limits provide protection for processes where excessive power can cause damage. automatic sensor probe break detection, for fail-safe operation, causes the controller to default to a programmed output power (upscale or downscale burnout). programmable output cycle time, output hysteresis and dampening can reduce output activity without degrading control accuracy. the main outputs can operate in pid, on/off, or manual control modes. control and alarm outputs in addition to the linear dc outputs, there are up to three types of on/off outputs.these outputs can be relay, logic, or triac for control or alarm purposes. relay outputs can switch user applied ac or dc voltages. logic/ssr drive outputs supply power to external ssr power units. one logic/ssr drive output can control up to four ssr power units at one time. the triac output supplies one amp of ac current for control of an external ac relay or triac device. auto-tune the t48 has an auto-tune feature which, on demand, automatically determines the pid control parameters for a particular thermal process. after completion of auto-tune, the pid parameters are automatically optimized for that process and loaded into non-volatile memory. the operator may view and modify the parameters as desired. auto-tune may be invoked either at start-up or at setpoint, depending on the process requirements. an auto-tune programmable dampening factor produces various levels of process control and response characteristics. rs485 communications the rs485 communications option allows the connection of up to 32 devices on a single pair of wires with a distance of up to 4,000 feet and a maximum baud rate of 9600. since the same pair of wires are used for both transmit and receive, only one way communication is possible at any given time. the controller has a programmable response time to allow the host device adequate time to release the communication line for a transmission. selected parameters from the t48 can be interrogated or changed, and alarm output(s) may be reset by sending the proper command code via serial communications. it is also possible to invoke auto-tune through the serial port. serial communications used with sfcrm software allows for easy controller parameter configuration by computer. heating and cooling systems the t48 is available with dual outputs to provide heating and cooling to those processes that require them. for example, many extruder applications require both heating and cooling to maintain accurate extruder barrel and die temperatures. the t48 is easily configured for these types of applications.
5 controller programming front panel program disable allows all of the controllers set-ups to be locked-out from further operator intervention after the initial set-up. the following four programming modes allow the controller to adapt to any required user-interface level: unprotected parameter mode protected parameter mode hidden function mode configuration parameter mode unprotected parameters mode * the unprotected parameters mode is accessible from the normal display mode when program disable is inactive or when the proper access code number from the protected parameter mode is entered. the configuration parameter modes can be accessed only from this mode. sp -

multiple unit/remote setpoint application eight t48 controllers are used in a drying oven. each t48 controls a zone within the oven. depending upon the material to be dried, and its initial moisture content, the drying setpoint temperature varies. a master t48 controller transmits setpoint via linear dc output. this signal is received as a remote setpoint signal by the other slave controllers. whenever the master controllers setpoint is changed, the slave controllers setpoint changes automatically. the remote setpoint input at each slave controller can be scaled independently. 7 oem paint sprayer application an oem manufacturing spray painting equipment utilizes the t48 to maintain optimum paint temperature. in addition to the low cost, the 1/16 din package size permits the oem to design temperature control into various sized painting equipment, from small hand sprayers to large paint booths. the heating element used to heat the paint, is connected to the main control output (op1) programmed for on/off control. alarm 1 is programmed as band inside acting, so that as long as the paint temperature is within manufacturers specifications for temperature, the go light is on. alarm 2 is programmed as band outside acting so that the no go light is lit when the paint temperature is more than 12 outside the manufacturers specifications of 140 to 150f. 11 12 14 13 10 9 8 7 6 5 4 3 2 1 user input comm. tc + rtd al2/o2 comm. al1 o1 n.o.
