GENERAL DESCRIPTION

The TSC is a setpoint controller suitable for time vs. temperature, process control applications. The TSC accepts signals from a variety of temperature sensors (thermocouple and RTD elements), precisely displays the process temperature, and provides an accurate output control signal (time proportional or linear) to maintain a process at the desired control point. A comprehensive set of easy to use steps allows the controller to solve various application requirements. The user input can be programmed to perform a variety of controller functions.

Dual 4-digit displays allow viewing of the measured temperature value and setpoint or temperatureandprofile status simultaneously.Front panel indicators inform the operator of controller status and output states. Replaceable output modules (Relay, Logic/SSR drive or Triac) can be fitted to the main control output, alarm output(s) or timed event output(s), and cooling output.

The TSChas been designedto simplify the set-up andoperation of acontrolled setpoint profile program. The setpoint program is easily entered and controlled through thefront panel. Fulldisplay capabilities keepthe operator informedof the process temperature, profile status, output states, and setpoint value.

The controller can operate in the standard PID control mode for both heating or cooling, with on-demand Auto-Tune which establishes the PID gain set. The PID gain set can befine tunedby the operator at any time or may be lockedfrom further modification.The unit can be transferred to the manual control mode providing the operator with direct control of the output.

The TSC features four programs or profile recipes, each with up to eight ramp/soak segments,which can beeasily stored and executed atany time. Longer profiles canbe achieved bylinking one ormore profiles together,creating a single profile of up to 32 ramp/soak segments. Temperature profile conformity is assured during either soak (hold) phases or both ramp and hold phases by an adjustable error band parameter. The program repeat function cycles the profile either a set number of times or continuously. Power-on options automatically re-start, stop, or resume a running profile. The profile can be controlled via the front panel buttons, the user input, or the serial communications option.

Four control points, each having a setpoint and PID parameter set, are available for instant front panel implementation during batch changeover, or other process conditions. A control point may have its PID gain set values disabled when implementing the control point.

The optional RS-485 multidrop serial communications interface provides the capability of two-way communication between a TSC unit and other compatible equipment such as a printer, a programmable controller, or a host computer. In multipoint applications the address number of each unit on the line canbe programmed from 0-99. Up to thirty two units can be installedon a single pair of wires. The Setpoint value, % Output Power, Setpoint Ramp Rate, etc. can be interrogated or changed, by sending the proper command code via serial communications. Alarm output(s) may also be reset via the serial communications interface option.

Optional alarm output(s) may be configured to operate as a timed event output or as a standard alarm output. As an alarm output it may be configured to activate according to a variety of actions (Absolute HI or LO, Deviation HI or LO,or Band IN or OUT)with adjustable hysteresis. Also, astandby feature suppresses the output(s) on power-up until the temperature stabilizes outside the alarm region. Timed event output(s) allow the controller to activate other equipment while a profile is running. Each profile can define up to 16 event states (phases), for each output(s).

An optional secondary output is available for processes that require cooling, which provides increased control accuracy and response.

The optional linear 4-20 mA or 0 to 10 VDC output signal is available to interface with final actuators, chart recorders,indicators, orother controllers.The output signal canbedigitally scaled andselected to transmit oneof the following:

% Output Power Measurement Value Deviation

Measurement Value Setpoint Value

An optional NEMA 4X/IP65 rated bezel is available for washdown and/or dirty environments, when properly installed. Modern surface-mount technology, extensive testing, plus high immunity to noise interference, makes the controller extremely reliable in industrial environments.

SAFETY SUMMARY

All safety relatedregulations, local codes andinstructions that appear inthe 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 TSC 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 tothe unit. An independent and redundant temperature limit indicator with alarm outputs is strongly recommended. Red Lion Controls model IMT (thermocouple) or model IMR (RTD) units may be used forthis purpose. The indicators should have input sensors andAC power feeds independent from other equipment.

INSTALLATION & CONNECTIONS

INSTALLATION ENVIRONMENT

The unit should be installed ina location thatdoes not exceedthe maximum operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided.

Continuous exposure to directsunlight may accelerate the aging process of the bezel. The bezel should be cleaned only with a soft cloth and neutral soap product. Do NOT use solvents.

Do not use tools of any kind (screwdrivers, pens, pencils, etc.) To operate the keypad of the unit.

STANDARD UNIT INSTALLATION

Prepare the panel cutout to the dimensions shown in the installation figure. Remove the panel latch and cardboard sleeve from the unit and discard the cardboard sleeve. The unit should be installed with the bezel assembly in place. Insert the unit into the panel cutout. While holding the front of the unit in place, push the panel latch over the rear of the unit so that the tabs of the panel latch engage in the slots on the case. The panel latch should be engaged in the farthest forward slots possible. Tighten the screws evenly until the unit is snug in the panel.

NEMA 4X/IP65 UNIT INSTALLATION

The optional NEMA 4X/IP65 TSC Controller is designed to provide a watertight seal inpanels with aminimum thickness of1/8 inch. The unitmeets NEMA 4X/IP65 requirements for indoor use, when properly installed. The units are intended to be mounted into an enclosed panel. Prepare the panel cutout to the dimensions shown in the installation figure. Carefully apply the adhesive side of the panel gasket to the panel cutout. Remove the panel latch and cardboard sleeve from the unit and discard the cardboard sleeve. The unit should be installed with the bezel assembly in place and the bezel screws tightened slightly. Insert the unit into the panel cutout. While holding the front of the unit in place,push the panellatch over therear of theunit so thatthe tabs of the panel latch engage in the slots on the case. The panel latch should be engaged inthe farthest forward slot possible.To achieve a proper seal, tighten the latch screws evenly until the unit is snug in the panel (torque to approximately 7 in-lbs [79 N-cm]). Do NOT over-tighten the screws.

PANEL INSTALLATION & REMOVAL

Note: The installationlocation of the controlleris important. Be sureto keep it

away from heat sources (ovens, furnaces, etc.), away from direct contact with caustic vapors, oils, steam, or any other process by-products in which exposure may effect proper operation.

Note: Prior to applying power to the controller, the internal AC power

selector switch must be set. Damage to the controller may occur if the switch is set incorrectly.

-8-

UNIT REMOVAL PROCEDURE

To remove a NEMA 4X/IP65 or standard unit from the panel, first unscrew and remove the panel latch screws. Insert flat blade screwdrivers between the latch and the case on the top and bottom of the unit so that the latches disengage from the grooves in the case. Push the unit through the panel from the rear.

REMOVING BEZEL ASSEMBLY

The bezel assembly must be removed from the case to install or replace output modules, to select the input sensor type, or to set the 115/230 VAC selector switch.To remove a standard bezel assembly (without bezel securing screws) press the latch under the lower bezel lip and withdraw the bezel assembly. To remove the sealed NEMA 4X/IP65 bezel assembly, loosen the two bezel securing screws until a slight “click” is felt (the screws are retained in the bezel) and withdraw the assembly. It is recommended to disconnect power to the unit and to the output control circuits to eliminate the potential shock hazard with the bezel assembly removed.

Note: The bezel assembly contains electronic circuits which are damaged by

static electricity. Before removing the assembly, discharge stray static

electricity on your body by touching an earth ground point. It is also

important that the bezel assembly be handled only by the bezel itself.

Additionally, if it is necessary to handle a circuit board, be certain that

hands arefree from dirt,oil, etc., to avoid circuit contamination which may

lead to malfunction.

INSTALLING BEZEL ASSEMBLY

To install the standard bezel assembly, insert the assembly into the case until the bezel latch snaps into position.

To install the NEMA 4X/IP65 bezel assembly, insert the assembly into the case and tighten the bezel screws uniformly until the bezel contacts the case and then turn each screw another half turn to insure a watertight seal (do not over-tighten screws).

Note: When substituting or replacing a bezel assembly, be certain that it is

done with the same model using the same Output Modules. Damage to the

controller may resultif the unit’s output modulesare not the same.A NEMA

4X/IP65 and a standard bezel assembly are NOT interchangeable.

OUTPUT MODULES

The maincontrol, optional alarm,and optional cooling output socketsmust be fitted with the appropriate output module. Output modules are shipped separately and must be installed by the user.

Output Variations Without RS-485 Option

The Dual Alarm or the Cooling with Alarm output, without the RS-485 option, has independent outputs. Therefore, the cooling output and/or alarm output(s) can be installed with any combination of output modules.

Output Variations With RS-485 Option

The Dual Alarm or the Cooling with Alarm output, with RS-485 option, does not have independent outputs. In this case, the cooling output and/or alarm output(s) must have the same type of output modules installed since they share the common terminal.

Installing Output Modules

To install an output module into the controller, remove the bezel assembly from the case (see Removing Bezel Assembly). Locate the correct output module socket(OP1, AL1, or AL2/OP2, seehardware figure or label outside of case) and plug the output module into the socket. No re-programming is required. Ifchanging an output moduletype, be sure the appropriate output interface wiring changes are made. Re-install the bezel assembly when complete.

SELECT AC POWER (115/230 VAC)

The AC power to the unit must be selected for either 115 VAC or 230 VAC. The selectorswitch is located insidethe case nearthe rear ofthe unit onthe main circuit board (Seehardware figure and/orlabel on inside oroutside of case).The unit is shipped from the factory with the switch in the 230 VAC position.

Note: Damage to the controller may occur if the AC selector switch is set

incorrectly.

EMC INSTALLATION GUIDELINES

Although this unit is 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 electrical noise, source or coupling method into the unit may be different for various installations. Listed below are some EMC guidelines for successful installation in an industrial environment.

1. The unit should be mounted in a metal enclosure, which is properly

connected to protective earth.

2. Use shielded (screened) cables forall Signaland Control inputs. The shield

(screen) pigtail 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 only at the panel wherethe unit ismounted to earth

ground (protective earth).

b. Connect the shield to earth ground at both ends of the cable, usually

when the noise source frequency is above 1 MHz.

c. Connect the shieldtocommon of the unitand leavethe other end of the

shield unconnected and insulated from earth ground.

3. Never run Signalor 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 in 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.

4. Signal or Control cables within an enclosure should be routed as far

away as possible from contactors, control relays, transformers, and

other noisy components.

5. In extremely high EMI environments, the use of external EMI suppression devices, such as ferrite suppression cores, is effective. Install them on Signal and Control cables as close to the unit as possible. Loop the cable through the core severaltimes or usemultiple cores oneach cable foradditional protection. Install line filters on the power input cable to the unit to suppress power line interference. Install them near the power entry point of the enclosure. The following EMI suppression devices (or equivalent) are recommended: Ferrite Suppression Cores for signal and control cables:

Fair-Rite # 0443167251 (RLC #FCOR0000) TDK # ZCAT3035-1330A Steward #28B2029-0A0

Line Filters for input power cables:

Schaffner # FN610-1/07 (RLC #LFIL0000) Schaffner # FN670-1.8/07 Corcom #1VR3

Note: Reference manufacturer’s instructions when installing a line filter.

6. Long cable runs are more susceptible to EMI pickup than short cable runs. Therefore, keep cable runs as short as possible.

7. Switching of inductive loads produces high EMI. Use of snubbers across inductive loads suppresses EMI. Snubbers:

RLC #SNUB0000

WIRING CONNECTIONS

After the unit has been mechanically mounted, it is ready to be wired. All

wiring connections are made on a fixed terminalblock. Whenwiring theunit, use the numbers onthelabel to identifythe position number withthe proper function.

All conductors should meet voltage and current ratings for each terminal.

Also cabling should conform to appropriate standards of good installation, local codesand regulations. It is recommended that powersupplied to the unit (AC or DC) be protected by a fuse or circuit breaker. Strip the wire leaving approximately ¼"(6 mm) bare wire exposed (stranded wires should betinned with solder). Insert the wire into the terminal and tighten the screw until the wire is clamped in tightly. Each terminal can accept up to two, 18-gage wires. Wire each terminal block in this manner.

-12-

Signal Wiring

When connecting the thermocouple or RTD leads, be certain that the connections are clean and tight. If the thermocouple probe cannot be connected directly to the controller, thermocouple wire or thermocouple extension-grade wire must be used to extend the connection points (copper wire will not work). Always refer to the thermocouple manufacturer’s recommendations for mounting, temperature range, shielding, etc. For multi-probe temperature averaging applications, two or more thermocouple probes may be connected to the controller (always use the same type). Paralleling a single thermocouple to more than one controller is NOT recommended. Generally, the red wire from the thermocouple is negativeand connected to the controller’s common.

RTD sensors are used where a higher degree of accuracy and stability is required when compared to thermocouples. Most RTD sensors available are the three wire type. The third wire is a sense lead for canceling the effects of lead resistance of the probe. Four wire RTD elements may be used by leaving one of the sense leads disconnected.

Two wire RTD sensors may be used in either of two ways: A) Install a shorting wire between terminals #8 & #9. A temperature offset

error of 2.5°C/ohm of lead resistance will exist. The error may be

compensated for by programming a temperature offset. B) Install a copper sense wire of the same wire gage as the RTD leads. Attach

one end of the wire at the probe and the other end to terminal #8. Complete

lead wire compensation will be in effect. (preferred method)

Note: With extended cable runs, be sure the lead resistance is less than 10

ohms/lead.

The programmed User Input function is performed when terminal #7 is used in conjunction with common (terminal #10). Any form of mechanical switch may beconnected to terminal #7.Sinking open collector logicwith less than 0.7 V saturation may also be used (no pull-up resistance is necessary).

Note: Do not tie the commons of multiple units to a single switch. Use either a

multiple pole switchfor gangedoperation or a singleswitch for each unit.

AC Power Wiring

Primary ACpower is connected to the separate twoposition terminal block labeled AC. To reduce the chance of noise spikes entering the AC line and affecting the controller, a separate AC feed should be used to power the controller. Be certain that the AC power to the controller is relatively “clean” and within the -15%, +10% variation limit. Connecting power from heavily loaded circuits orcircuits that also power loads thatcycle on and off, (contacts, relays, motors, etc.) should be avoided.

FRONT PANEL DESCRIPTION

The front panel bezel material is flame and scratch resistant tinted plastic. Available is an optional NEMA 4X/IP65 version which has a bezel that meetsNEMA 4X/IP65 requirements, when properly installed. There are two 4-digit LED displays, a red upper Main Display and a lower green Secondary Display.

There are up to six annunciators depending on options installed, with red backlighting, which illuminate to inform the operator of the controller and output status.

Four front panel buttons are used to access different modes and parameters. The following is a description of each button.

BUTTON FUNCTIONS

DSP -In the normaloperating mode, the Display

(DSP) button is used to select one of the four

parameters in the secondary display or

indicate the temperature unit’s (°F or °C). In

the ConfigurationParameter Modes, pressing

this button causes the unit to exit (escape) to

the normal operating mode with NO changes

made to the selected parameter.

UP, DN - In the normal operating mode, the

up/dn buttons can be used to modify the setpoint value, % output power (manual mode only), the profile status, or the profile phase time remaining, when viewed in the secondary display. The variables foreach parameter areselected using theup/dn buttons. In the Hidden Mode, the up/dn buttons can be used to reset alarm(s), event output(s), select auto or manual operation, invoke or cancel auto-tune, load a control point, or change the status of a running profile.

PAR - The Parameter (PAR) button is used toaccess, enter, andscroll through

the available parameters in any mode.

OPERATION OVERVIEW

CONTROLLER POWER-UP

Upon applying power, the controller delays control action and temperature indication for five seconds to perform several self-diagnostic tests and displays basiccontroller information. Initially, the controller illuminates both displays and all annunciators to verify that all display elements are functioning. Following, the controller displays the programmed input sensor type in theMain display (verify thatthe input select sensor jumpermatches the programming). Concurrently, it displays the current revision number of the operating system software in the bottom display. The controller checks for correct internal operation and displays an error message (E-XX) if an internal fault is detected (see Troubleshooting).

A profile can be programmed to Start (run mode), Stop (off mode), or Pause if it was runningonpower-up (see “ProfilePower Cycle Status Parameter”section).

Upon completion of this sequence, the controller begins control action by displaying the temperature and updating the outputs based upon the PID control value.

CONTROLLER POWER DOWN

At power down, the steady state control value as well as all parameters and control modes are saved, to provide a quick and predictable temperature response on the next power-up.

When powering down the process, it is important to power down the controller at the same time. This prevents the reset action of the controller from shifting the proportional band while the temperature is dropping, which prevents excessive overshoot on the next process start-up.

PROCESS START-UP

After starting the process, the controller’s PID settings must be initially “tuned” to the process for optimum temperature control. Tuning consists of adjusting the Proportional Band, Integral Time, and Derivative Time parameters to achieve the optimum response to a process disturbance. Once the controller is tuned, it may need to be re-tuned if the process has been changed significantly. Several options exist for tuning these parameters:

A) Use the controller’s built-in Auto-Tune feature (see Auto-Tune). B) Use a manual tuning technique (see manual tuning).

C) Use a third party tuning software package (generally expensive and not

always precise).

D) Use valuesbasedon control loopexperience or values froma similar process.

If the controller is a replacement, the PID settings from the unit being replaced may be used as good initial values. Be sure to consider any differences in the units and the PID settings when replacing. The PID settings may befine tuned by using thetechniques outlined in the PID Control section. After tuning the controllerto theprocess, it is important to power the load and the controller at the same time for best start-up response.

MANUAL (USER) & AUTOMATIC OPERATION

The controller can be transfered between Automatic control (closed loop; PID or ON/OFF control) and Manual control (open loop). Placing the controller inthe Manual Mode does not impede the advancement oroperation of a runningprofile. In the Hidden FunctionMode, the “trnf” parameter allows the operator to select the desired operating mode. To allow front panel switching between control modes, program the transfer (trnf) parameter to “Enbl” in the Lockout module. The User Input or RS-485 serial interface option may also be used to perform the auto/manual transfer function, independent of the setting in the Lockout module.

Manual operationprovides direct control of theoutput(s) from 0 to +100%, or -100% to +100% if cooling output is installed. The MAN (manual) annunciator flashes to indicate that the unit is in manual operation.

In theManual Mode, theoutput power canbe adjusted using the frontpanel arrow buttons when % output power is viewed in the lower display. If the % output power is locked or read only, then the output power can be adjusted in the unprotected parameter mode when OP is viewed. With the serial option, the % output power can be modified independent of what is viewed in the display as long as the unit is in the manual mode.

When transferring the controller mode from/to automatic, the control power output(s) remain constant, exercising true “bumpless” transfer. When transferring from manual to automatic, the power initially remains steady but integral action will correct (if necessary) the closed loop power demand at a rate proportionalto the IntegralTime. The programmable high andlow power limit values are ignored when the unit is in manual operation.

PROFILE OPERATING MODES

Run Mode

The controller is in the Run Mode when a profile is executing. While in the Run Mode, the profile can be stopped (Off Mode), paused (Pause Mode) or advanced to the next phase. A profile is started and placed into the Run Mode either manually or automatically when the controller is powered-up. The advancement of the profile can be viewed in the secondary display.

Off Mode

The Off Mode signifies that all profiles are dormant. The Off Mode is achieved by manuallyterminating a profile in progress orby allowing a profile to run to completion. When a profile ends or is terminated, the active setpoint is the lasthold setpoint value.A profile terminated duringa ramp phaseresults in the activesetpoint value to be the setpointvalueat the instant oftermination. A profile terminated during a hold phase results in the active setpoint value to be the setpoint value at the hold level.

Pause Mode

The pause modesignifies that a profile isactive but the timebase is stopped. The pause mode is caused only by a manual action. Pausing a profile during a ramp phase stops the ramp and the controller maintains the setpoint value at the instant of the pause action. During hold phases, the timing of the hold phase is stopped. The use of pause mode effectively lengthens the total run time of a profile. Pause mode is indicated by “PAUS” flashing in the profile control status display. A profile can be placed in the pause mode via the front panel buttons, the user input, or the serial communications option. The unit remains in the pause mode until a continue operation is performed. The continue operation places the profile into the run mode.

PROFILE PAUSE MODE

-16-

Delay Mode

The Delay Modesignifies that a profileis active but thetime base, or profile advancement is stopped. This is caused by automatic action of the controller when the input temperature deviates more than a specified amount from the profile setpoint. The Delay Mode is similar to the pause mode, except the delay mode is invoked automatically by the controller.

The Profile Deviation Error Band programmed for a positive value, allows the Delay Mode to be invoked only during hold phases. A negative value allows the delaymode to be invokedduring “both” ramp and holdphases. The profile automatically resumes when the process temperature is within the prescribed error band value. The Delay Mode is indicated by “dEly” flashing in the profilecontrol status display and bya flashing decimal point inthe upper main display. The Delay Mode can be terminated manually by changing the deviation error band value to a larger value or to zero for off. The new error band value takes effect immediately.

CONTROLLING A PROFILE

Profile Start Operation

A profile always starts at the first ramp phase and the setpoint value ramps from the current temperature value. The profile can be programmed to ramp from a known setpoint value (see Ramp Phase section). Link-started profiles use the last target setpoint level as the starting point. A profile is started from the off mode, which places the controller into the run mode. To re-start a running profile from the beginning, it is necessary to first stop the profile.

CONFIGURATION OF PARAMETERS

As supplied from the factory, the controller parameters have been programmed to the values listed in the Quick Reference Tables. Theuser must modify the values, if necessary, to suit the application.

Operation and configuration of the controller is divided into five distinct operational/programming modes to simplify the operation of the controller: Normal Display Mode, Unprotected Parameter Mode, Protected Parameter Mode, Hidden Function Mode, and Configuration Parameter Modules.

S These parameters may not appear due to Note: In any mode or module, DSP returns

unit configuration or programming set-ups. the controller to the normal display mode.

-22-

PARAMETER ENTRY

The PAR button is used to select the desired parameter. To modify the parameter settinguse the UPand DOWN buttons, and thenpress PAR to enter the new value, the controller progresses to the next parameter. In a Configuration Parameter Module, pressing the DSP button causes the new value to be rejected, the controller displays “End”, and returns to the Normal Display Mode. For those parameters outside the Configuration Parameter Modules, the new value takes effect and is committed into controller memory WHILE the value is keyed in. The following is a list of these commonly modified parameters:

Setpoint Output Power Output Power Offset Proportional Band Integral Time Derivative Time Alarm 1 Value Alarm 2 Value

Note: While in a Configuration Parameter Module, all new parameters are

rejected andthe old ones recalled ifpower is lost to thecontroller. If power

is removed while modifying ANY parameter, be certain to check the

parameter for the proper value.

NORMAL DISPLAY MODE

In the normal display mode, theprocess temperature is always displayed in the main display. By successively pressing the DSP button, one of five parameters can be viewed in the secondary display:

Temperature Setpoint % Output Power Profile Control Status Profile Phase Time Remaining Display Temperature Units (°F or °C).

Each of these displays can be independently locked out from appearing or from being modified by the user (see parameter lockout section).

Modifying A Secondary Display Parameter From The Front Panel

The controller must be in the normal display mode to modify any of the secondary display parameters. Temperature units symbol indicates the temperature scale (°For °C) and cannot bemodified from this mode.The other four parameters can bemodified when viewed in the secondary display (if not locked). Pressing the DSP button scrolls through the secondary display parameters. The following describes how these parameters can be modified when viewed in secondary display.

Setpoint Value Display

Use the up and down arrow buttons to modify the setpoint value when viewed (if not locked). If locked, the setpoint can be changed in the unprotected or protected mode when “SP” is viewed, independent of viewing in the secondary display. The setpoint value is constrained to the programmable setpoint limit values (SPLO & SPHI, input module 1).

The profilesetpoint value can be changed during profile operation to effect immediate changes to the profile. If locked, the target setpoint value can be changed when viewedin the protected mode. Permanentchanges to the profile setpoint value must be done in the profiles module (8-Pr). Changing the setpoint value may cause the profile to enter the delay mode if the errror band parameter is enabled.

The ramping setpoint value is displayed during ramp phases. Immediate changes made to the ramping setpoint value do not alter the ramp rate, but change the ramp time remaining to the next target setpoint level. This action either lengthens or shortens the total time remaining. The phase time remaining is effected the instant the setpoint value is changed.

The holding setpoint value isdisplayed during holdphases. A change to the holding setpointvalue causes the controller to immediately operateat the new setpoint level. In addition, the next ramp phase begins ramping from the modified setpoint value to the target setpoint value.

-23-

% Output Power Display

The % output power can only be changed when the unit is in the manual mode. The annunciator %PW lights when viewed, then use the up and down arrow buttons to modify the % output power (if not locked). If locked, the % output power canbe changed in theunprotected or protected modewhen “OP” is viewed, independent of viewing in the secondary display. The % output power is not constrained to the programmable output power limit values (OPLO & OPHI, output module 2).

Profile Control Status Display

The annunciator PGM lights when either the profile control status or the phase time remaining is displayed. The profile control status indicates the current mode ofa profile.The table shows variousdisplays for profile modes.

Profile Status Description

Display

OFF Profile is off. No profiles running. P1r1 Profile #1 is running and in ramp phase #1. P2H8 Profile #2 is running and in hold phase #8. P3r4 Profile #3 is running and in ramp phase #4. PAUS Profile is Paused (PAUS flashes). Currently running

profile is in the pause mode.

dEly Profile is Delayed (dEly flashes). Currently running

profile is in the delay mode.

The front panel buttons allow the operator to change the profile status. The operation of a profile is controlled directly from the profile control status display, if not locked (see controlling a profile section for details).

Profile Phase Time Remaining Display

The annunciator PGM lights when either the phase time remaining or the profile control statusis viewed. Use theup/down front panel buttonsto change the time remaining, if not locked. The ramp or hold phase time remaining can be changed duringprofile operation to effect immediatechanges to the profile. Permanent changes tothe profilemust be done inthe profiles module (8-Pr).

During ramp phases the display indicates the time remaining until the next hold phase. If the time remaining is changed during a ramp phase, the controller calculates a new, but temporary, ramp rate. The setpoint ramps at the new ramprate value tothe next setpoint level.The new ramprate may be at a faster or slower rate depending on the direction that the time remaining was changed. Changing the time remaining value to zero causes an immediate advance to the next hold phase, unless the profile is in the pause mode. In this case, when the profile is placed back into the run mode, the profile immediately advances to the next hold phase.

During hold phasesthe display indicates timeremaining until the nextramp phase. Changes to the time remaining during a hold phase effect the duration of the hold phase. A value of zero causes the profile to advance to the next ramp phase unless the profile is in the pause mode.

Changing the time remaining effects the total run time of the profile. When the profile is in the off mode, “0.0” minutes is displayed in the phase time remaining display.

-24-

UNPROTECTED PARAMETER MODE

The Unprotected Parameter Mode is accessed by pressing the PAR button from the normal display mode with program disable inactive. In this mode, the operator has access to the list of the most commonly modified controller parameters. At the end of the list, a configuration “access point” allows the operator to enter the configuration parameter modules. These modules allow access to the fundamental set-up parameters of the controller. When the program list has been scrolled through, the controller displays “End” and returns to the normal display mode. The unit automatically returns to the normal display mode if a button is not pressed within eight seconds.

HIDDEN FUNCTION MODE

Hidden Function Mode Reference Table

The Hidden Function Mode is only accessible from the normal display mode by pressing and holding the PAR button for three seconds. In this mode, five controller functions can be performed.

Automatic/Manual Transfer Initiate/Cancel Auto-tune Reset Alarm/Timed Event Output(s) Load Control Point Control Profile Status

Each function may be “locked out” in the configuration parameter lockouts module. The PAR button is used to scroll to the desired function and the up and down buttons are used to select the operation. Pressing the PAR button while the function is displayed executes the function and returns the unit to the normal display mode. Pressing the DSP button exits this mode with no action taken. The unit automatically returns to the normal display mode if a function is not executed in eight seconds.

CONFIGURATION PARAMETER MODULES

Accessible from the unprotected parameter mode, the configuration parameter modules allow the operator access to the controller’s fundamental set-up parameters. There are nine possible configuration stages that can be accessed. At the configuration stage access point “CNFP”, the operator uses the UP & DOWN arrow buttons to select the desired configuration parameter module. Press the PAR button to enter the module where the settings can be viewed or modified.

The PAR button is used to scroll through the parameters and the UP and DOWN buttons are used to modify the parameter value. The PAR button enters the desired choice, advancing to the next parameter. The operator can press theDSP button to exit (escape) without modifying the parameter, which returns the unit to the normal display mode. After the parameters in a module are viewed or modified, the unit returns to the configuration access point, allowing access to other modules.

INPUT MODULE (1- IN)

The controller has several input set-up parameters which must be programmed prior to setting any other controller parameters.

Input Type (type)

Select from thelist of various thermocouple and RTDsensors.Be sure to set the internal input select jumper to the appropriate position (TC or RTD, see select input sensortype orthe label on insideof case for location ofjumper).

The following is a list of the possible sensors:

tc-t - Type T TC tc-E - Type E TC tc-J - Type J TC tc-k - Type K TC

tc-r - Type R TC tc-S - Type S TC tc-B - Type B TC tc-N - Type N TC

LIN - Linear mV display

r385 - 385 curve RTD r392 - 392 curve RTD

rLIN - Linear ohms display

Temperature Scale (SCAL)

Select either degreesFahrenheit (°F) or degrees Celsius(°C). If changed, be

sure to check All parameters.

Temperature Resolution (dCPt)

Select either 1 or 0.1 degree resolution. If changed, be sure to check All

parameters.

Input Signal Filter (FLtr)

Select the relative degree of input signal filtering. The filter is an adaptive digital filter which discriminates between measurement noise and actual process changes, therefore, the influence on step response time is minimal. If the signal is varying too greatly due to measurement noise, increase the filter value. Additionally, with large derivative times, control action may be too unstable for accurate control. Increase the filter value. Conversely, if the fastest controller response is desired, decrease the filter value.

INPUT MODULE (1- IN) (Cont’d)

Input Sensor Correction Constants (SPAN & SHFt)

If the controller temperature disagrees with a reference temperature instrument orif the temperature sensor has a known calibration, thecontroller temperature can be compensated by a correction slope (SPAN) and offset (SHFt).

The following equation expresses the relationship:

Desired Display Temp = (Controller Temp x SPAN) + SHFt

EX1.) The controller reads 293°F while a reference instrument indicates

300°F. A SHFT value of +7°F corrects the controller indication to match

the reference. (Use SPAN = 1.000) EX2.) A thermocouple probe is calibrated over the region of operation to

achieve more accurate temperature control. The calibration results are as

follows:

Desired Temperature Thermocouple Output

400.0F 395.0F

800.0F 804.0F

SPAN =

SHFT = 400F - (0.978 x 395F) = 13.7°F

SPAN value of 0.978 and SHFT value of 13.7°F corrects the indicator to the probe.

Setpoint Limit Values (SPLO & SPHI)

The controller has programmable high and low setpoint limit values to restrict the setting range of the setpoint. Set the limit values so that the temperature setpoint value cannot be set outside the safe operating area of the process.

804F - 395F

SPAN - 0.001 to 9.999

SHFt - -999 to 9999

800F - 400F

SPLO - -999 to 9999

SPHI - -999 to 9999

= 0.978

Auto Setpoint Ramp Rate (SPrP)

The setpoint can be programmed to ramp independent of the controller’s display resolution. The setpoint ramp rate can reduce thermal shock to the process, reduce temperature overshoot on start-up or setpoint changes, or ramp the process at a controlled rate

SPrP - 0.1 to 999.9 degrees/minute

A ramp value of zero disables setpoint ramping. If the user input is programmed for setpointramp, it affects the enablingand disabling of setpoint ramping (refer to user input section). Setpoint ramping is initiated on power-up or when the setpoint value is changed and is indicated by a decimal point flashing in the far right corner of the main display.

Note: The autosetpoint ramp rate is independentfromthe operation of aprofile.

Once the rampingsetpoint reaches the target setpoint, thesetpoint ramp rate is disengaged until the setpoint is changed again. If the ramp value is changed during ramping, the new ramprate takes effect.If the setpointis ramping prior to invoking Auto-Tune, the ramping is suspended during auto-tune and then resumed afterward usingthe current temperature asa starting value. Deviation and band alarms are relative to the target setpoint, not the ramping setpoint. If the analog output is programmed to transmit the setpoint value, the instantaneous ramping setpoint value is transmitted.

-30-

Note: Depending on the ramp rate relative to the process dynamics, the actual

process temperature may not track the ramping setpoint value.

User Input (InPt)

The User Input requires the input to be in its active state for 100 msec minimum to perform the function. The unit will execute all functions in 100 msec, except the print request function which requires 110 to 200 msec for a response. Afunction is performed when the User Input (terminal 7),is used in conjunction with common (terminal 10).

Note: Do not tie the commons of multiple units to a single switch. Either use a

multiple pole switch for ganged operation or a single switch for each unit.

Transition activated functions do not occur on controller power-up.

Below is a list of the available functions. PLOC - Program Lock. A low level enables the program disable function

which places the unit in the Protected Parameter Mode. A high level

disables the program disable function.

Note: Front panel disable is possible without using this program lock

function, refer to front panel program disable section.

ILOC - Integral Action Lock. A low level disables the integral action of the

PID computation. A high level resumes the integral action.

trnF - Auto/Manual Transfer. A negative transition places the unit in the manual

(user) mode and a positive transition places theunit in the automatic operating

mode. The output is “bumpless” when transferring to either operating mode.

SPrP - Setpoint Ramp. A low level terminates auto setpoint ramping and the

controller operates at the target setpoint. Terminating auto setpoint

ramping is the same as setting the ramp rate to zero (SPrP = 0.0). A high

level enables the auto setpoint ramp rate.

Note: This does not operate with a profile.

ALrS - Alarm/Timed Event Output Reset. If the alarm option is installed, a

low level resets the alarm/timed event output(s) to their inactive state as

long as the user input is low.

Prnt - Print Request. A low level transmits the print options selected in the

serial communications module(6-SC). If the user input isheldlow, after the

printing is complete a second print request is issued.

CP -Control Point Select.A high to low transitionloads Control Point 2 into the

memory of the controller. The controller now operates with data of Control Point 2.A low to high transition loads ControlPoint 1 into the memoryof the controller. The controller now operates with data of Control Point 1.

Note: Control Point data loaded into memory overwrites the existing

data setpoint and optionally the PID gain set. Control Points may be loaded during profile operation.

P1rH - ProfileRun/Pause. A low level pausesany running profile. A highlevel

allows a pausedprofile to resume. Alow to high transition startsProfile 1, if no other profile was running.

P1rS - Profile Run/Stop. A low level stops any running profile. A high level

allows any profile to run. A low to high transition always starts profile 1.

-31-

OUTPUT MODULE (2-OP)

The controller has parameters which affect how the main control output

(OP1) responds to temperature changes and sensor failures.

Time Proportioning Cycle Time (CYCt)

The selection of cycletime dependson the time constant of the process and

the type of output module used.

CYCt - 0 to 120 seconds

For best control, a cycle time equal to 1/10 of the process time constant is recommended; longer cycle times could degrade temperature control, and shorter cycle times willprovide littlebenefit at the expense of shortened relay life. When using a Triac module or a Logic/SSR drive output module with the SSR Power Unit, a relatively short cycle time may be selected.

A setting ofzero keeps the main controloutputand front panel indicatoroff. Therefore, if usingthe analog outputfor control, themain output and indicator can be disabled.

Output Control Action (OPAC)

For heat and cool applications, the main output (OP1) should be used for heating (reverse acting) and the optional cooling output (OP2) should be used for cooling (direct acting).

OPAC - rEv (Reverse acting)

drct (Direct acting)

If drct (direct acting) is selected, the main output (OP1) is direct acting and the cooling output (OP2) is reverse acting.

Note: When using a relay output module, the control action may also be

reversed by using the normally closed contacts.

The linear DC analog output, when assigned to output power (OP) for control purposes, will always follow the controller output power demand. A direct acting linear output signal can be implemented in two ways:

1. Use “direct” for output control action (OPAC).

2. Interchange thetwo analog output scaling points ANLO& ANHI (see linear

DC analog output in the output parameter module section).

Output Power Limits (OPLO & OPHI)

Enter the safe output power limits for the process. These parameters may also be used to limit the minimum and maximum controller power due to process disturbances or setpoint changes to reduce overshoots by limiting the process approach level.

OPLO & OPHI - 0 to 100%

If the cooling option is installed, the limits range from:

OLO & OPHI - -100 to 100%

With the coolingoption installed, the Lower Limit canbe set to less than0% to limit maximum coolingor set to greater than 0% to limit minimum heating. Set the High Limit to less than 0% to limit minimum cooling or greater than 0% to limit maximum heating. When controlling power in the manual mode, the output power limits do not take affect.

Sensor Fail Preset Power (OPFL)

If a failed sensor is detected, the control output(s) default to a preset power output.

OPFL - 0% (OP1 output full “off”) to 100% (OP1 output full “on”)

If the cooling option is installed, the range is extended from:

OPFL - -100% to +100%

At 0%both outputs are off, at 100% OP1is on and OP2 is off, andat -100% OP2 is on and OP1 is off. The alarm outputs always have an up-scale drive (+9999), independent of this setting, for failed sensor.

ON/OFF Control Hysteresis Band (CHYS)

The controller can be placed in the ON/OFF control mode by setting the proportional band to 0.0%. The control hysteresis value affects only the main control output (OP1).

CHYS - 1 to 250 degrees

The hysteresis band should be set to a minimum value to eliminate output chatter at the setpoint. Generally, 2 to 5° is sufficient for this purpose. Set the hysteresis band to a sufficient level prior to invoking Auto-Tune.

-32-

Auto-Tune Damping Code (tcod)

Prior to invoking Auto-Tune, the damping code should be set to achieve the desired damping level under PID control. When set to 0, this yields the fastest process response with some overshoot. A setting of 4 yields the slowest response with the least amount of overshoot. Damping codes of 0 or 1 are recommended for most thermal processes.

DAMPING CODE FIGURE

Note: Actual responses may vary depending on the

process, step changes, etc.

Linear DC Analog Output (ANAS, ANLO, & ANHI) (Optional)

The Linear DCoutput can beprogrammed to transmit oneof four controller parameters:

ASSIGN DC OUTPUT (ANAS):

INP - Scaled input process value OP - Percent output power dEV - Process setpoint deviation SP - Process setpoint value

With high and low digital scaling points, the range of the Linear DC output

can be set independent of the controller’s range.

ANLO (4 mA or 0 VDC) - -999 to 9999

ANHI (20 mA or 10 VDC) - -999 to 9999

This allows interfacing directly with chart recorders, remote indicators, slave controllers, or linear power control units. The output is isolated from input common and located on rear terminals #11 (OUT+) & #12 (OUT-). When usingthe linearDC analog output for main control by assigning theDC output forpercent output power, the frontpanel indicator OP1 can bedisabled by setting the time proportioning cycle time equal to zero. This also disables the main control output, OP1.

If transmitting the setpoint value, (for cascaded control with additional controllers), the controller transmits the instantaneous ramping setpoint, not the target value, when running a profile.

This also applies if the analog output is configured for process setpoint deviation (dEV).

EX1.) Chart Record Process Display Value (0 to 10 VDC):

The process range is 300-700. Programming 300 for ANLO (0 VDC value) and 700 for ANHI (10 VDC value) yields full scale deflection for a chart recorder (0 to 10 VDC). The 0 to 10 VDC output is assigned to transmit the input process (ANAS = INP).

EX2.) Linear Control Output (4 to 20 mA):

A linear DC input power control unit is used for process control. Programming 0.0% for ANLO (4 mA value) and +100.0% for ANHI (20mA value) configures the output. The 4-20 mA output is assigned to transmit percent output power (ANAS = OP).

-33-

LOCKOUTS MODULE (3-LC)

The controller can be programmed to limit operator access to various parameters, control modes, and display contents. The configuration of the lockouts is grouped into three sections: Lower Display Lockouts, Protected Mode Lockouts and Hidden Mode Lockouts.

Lower Display Lockouts (SP, OP, P-cs, P-tr, UdSP)

The contentsof the secondarydisplay can be changed inthe normal display mode by successively pressing the DSP button. This scrolls through the four possible display parameters, if enabled. Each parameter can be set for one of the following:

LOC (Lockout) - Prevents the parameter from appearing in the

secondary display.

rEd (Read only) - Parameter appears, but cannot be modified.

Ent (Entry) - Parameter appears and can be modified.

The five lower display content possibilities are:

SP - Setpoint Value

OP - % Output Power

P-CS - Profile Control Status

P-tr - Profile Phase Time Remaining

UdSP - Temperature Units

If all parameters are set to lock “LOC”, the display will remain on the last parameter that was viewed.

Note: If a parameter is active in the lower display and then subsequently

locked out, press “DSP” once in the normal display mode to remove it from

the display.

Protected Mode Lockouts (Code, PID, & AL)

The protected mode is active when program disable is active. The PID and

Alarm parameters can be set for one of the following:

LOC (Lockout) - Prevents the parameter from appearing in the display

rEd (Read only) - Parameter appears, but cannot be modified.

Ent (Entry) - Parameter appears and can be modified.

The PID setting allows access to Proportional Band (ProP), Integral Time (Intt), and Derivative Time (dErt) parameters. Alarm 1 and 2 values (AL1 & AL2) may also be locked out if installed.

A code number to enter the unprotected mode can be programmed into the controller. To enter the unprotected mode from the protected mode, the code number must match the code number entered. Refer to front panel program disable section for access levels.

Code-0to250

Hidden Mode Lockouts (ALrS, CPAC, PrAC, trnF, & tUNE)

The hidden mode is accessible from the normal display mode by pressing and holding thePAR buttonfor three seconds. Theparameters can be set for:

LOC (Lockout) -Prevents theparameter from appearing inthe display. ENbL (Enable) - Allows operator to perform function.

The five controller functions are executed in hidden mode and are accessible independent of the status of program disable.

ALrs - Reset (override) an alarm/timed event output(s).

trnF - Transfer controller from or to automatic to manual operation.

CPAC - Load 1 of the 4 control points (CP).

PrAC - Allows the operator to start one of the 4 profiles.

If a profile is running, the status (Adnc, Cont, PAUS, or OFF) can be changed.

tUNE - Invoke or cancel Auto-Tune.

-34-

ALARM MODULE (4-AL) (OPTIONAL)

The controller maybe optionally fitted withthe dual alarmoption (AL1 and AL2), ora single alarm with thecooling output option (AL1 and OP2). Oneof three types of output modules (Relay, Logic/SSR Drive or Triac) must be ordered separately and installed into the alarm channel socket.

Note: Units with RS-485 serial option must have the same type of modules

installed for the Dual Alarms setup.

The output modules may be replaced or interchanged (with appropriate wiring considerations) at any time without re-programming the controller. With an open sensor, the alarm outputs are up-scale drive (+9999) and with a shorted sensor (RTD only) they are down-scale drive (-9999).

A frontpanel annunciator illuminates to indicate that the alarm outputis on (AL1 for alarm 1 and AL2 for alarm 2).

Note: When deviation low-acting with positive alarm value (d-LO), deviation

high-acting with negative value (d-HI), or Band inside-acting (b-IN) is

selected for the alarm action, the indicator is “OFF” when the alarm

output is “ON”.

The alarm values can be accessed in configuration module (4-AL), the unprotected mode, and in the protected mode, if not locked.

CAUTION: In applications where equipment or material damage, or risk to

personnel due to controller malfunction could occur, an independent and

redundant temperature limit indicator with alarm outputs is strongly

recommended. Red Lion Controls model IMT (thermocouple) or model

IMR (RTD) units may be used for this purpose. The indicators should have

independent input sensorsand ACpower feeds from theother equipment.

Alarm Action (Act1, Act2)

The alarm(s) maybe independentlyconfigured for one ofsix possible alarm modes or configured to operate as a timed event output(s). The timed event output(s) are programmed in profiles module 8 (8-Pr).

Note: If an alarm is programmed for Timed Event Output (P-Ev), the

remaining alarm parameters are not applicable.

Absolute High Acting (A-HI) Absolute Low Acting (A-LO) Deviation High Acting (d-HI) - Tracks Setpoint Value Deviation Low Acting (d-LO) - Tracks Setpoint Value Band Inside Acting (b-in) - Tracks Setpoint Value Band Outside Acting (b-Ot) - Tracks Setpoint Value Timed Event Output (P-Ev)

Alarms configured for deviation or band action, track the setpoint during ramp and hold phases of a profile. Deviation and band alarms trigger from the target setpoint when the auto setpoint ramp rate (SPrP) feature is enabled.

The alarm actionfigures describe the status ofthe alarm output and the front panel indicator for various over/under temperature conditions. (See output module “OUTPUT ON” state table for definitions, under installing output modules section.) The alarm output waveform is shown with the output in the automatic reset mode.

Note: Select the alarm action with care. In some configurations, the front

panel indicator (LED) might be “OFF” while the output is “ON”.

-37-

Alarm Reset (rSt1, rSt2)

Each alarm reset action may be independently configured.

LAtC - Latching

Auto - Automatic

Latched alarms require operator acknowledgment to reset the alarm condition. The front panel buttons can be used to reset an alarm when the controller is in the hidden mode (see hidden function mode). An Alarm condition may alsobe reset viathe RS-485 serial interface or by theuser input. Automatic (Auto) reset alarms are reset by the controller when the alarm condition clears. The alarm reset figure depicts the reset types.

ALARM RESET SEQUENCE

-38-

Alarm Standby Delay (Stb1, Stb2)

The alarm(s) may be independently configured to exhibit a power-on, standby delay which suppresses the alarm output from turning “ON” until the temperature first stabilizes outside the alarm region. After this condition is satisfied, the alarm standbydelay is canceled and the alarm triggers normally, until the next controller power-on. The alarm standby delay figure depicts a typical operation sequence.

ALARM STANDBY DELAY SEQUENCE

Alarm Value (AL-1, AL-2)

The alarm values are either absolute (absolute alarms) or relative to the setpoint value(deviation and bandalarms). An absolutealarm value is the value that is entered. A relative alarm value is offset from the temperature setpoint value by the amount entered and tracks the setpoint value as it changes.

AL-1 and AL-2 - -999 to 9999

If the alarm action is set as a Band Alarm, then only a positive value can be entered.

AL-1 and AL-2 - 0 to 9999

Alarm Hysteresis (AHYS)

The alarm(s)values have a programmable hysteresis band to prevent alarm output chatter near the alarm trigger temperature. The hysteresis value should be set to eliminate this effect. A value of 2 to 5° is usually sufficient for most applications. A single alarm hysteresis value applies to both alarms.

Refer to the alarm action figures for the effect of hysteresis on the various alarm types.

AHYS - 1 to 250 degrees

Cooling Relative Gain (GAN2)

This parameter defines the gain of the cooling band relative to the heating band. A valueof 0.0 places thecooling output into ON/OFFcontrol mode with the Heat-Cool parameter (db-2) becoming the cooling output hysteresis. This may be done independent of the main output control mode (PID or ON/OFF). Relative gain isgenerally set to balancethe effects ofcooling to that ofheating for best control.

GAN2 - 0.0 to 10.0

COOLING OUTPUT PARAMETERS MODULE (5-02) (OPTIONAL)

The optional secondary output (OP2) operates as an independent cooling output for systems that use heating and cooling. One of the three types of output modules (Relay,Logic/SSR Drive orTriac) must be orderedseparately and installed into the cooling channel socket.

Note: Units withthe RS-485 serial communicationsoption must have the same

type of modules installed for the cooling output and alarm output.

The output modules may be replaced or interchanged (with appropriate wiring considerations) at any time without re-programming the controller.

The front panelindicator OP2 illuminateswhen the cooling outputis on. (See Output Module “OUTPUT ON” State Table for definition, under installing output modules section). Cooling output power is defined as ranging from

-100% (full cooling)to 0% (no cooling, unlessaheat-cool band overlap isused).

Cooling Cycle Time (CYC2)

A value of 0 turns off the cooling output, independent of cooling power demand.

CYC2 - 0 to 120 seconds

Example: If 10kW of heatingand 5kW ofcooling is available, initiallyset the

cooling gain to (2.0). The heat/cooloperation figure illustrates the effect of different gains.

-39-

Heat-Cool Overlap/Deadband (db-2)

This parameter definesthe area in which both heatingand cooling are active (negative value)or the deadband area betweenthe bands (positive value). The parameter units are degrees or tenth’s of degrees (depending on system resolution). If a heat/cool overlap is specified, the displayed percent output power is the sum of the heat power (OP1) and the cool power (OP2).

db-2 - -999 to 9999

If cooling relative gain is zero, the cooling output operates in the ON/OFF mode, with this parameter becoming the cooling output hysteresis (positive value only). This parameter should be set prior to Auto-Tune with cooling. The heat/cool operation figures illustrate the effects of different deadbands.

In practice with the cooling output, observe the controlled temperature characteristics and if the temperature remains above setpoint with a sluggish return, increase the cooling gain. Similarly, if the temperature drops too sharply with an overall saw-tooth pattern, decrease the cooling gain. Alter the heat-cool overlap until a smooth response in the controlled temperature is observed during band transition.

-40-

SERIAL COMMUNICATIONS MODULE (6-SC) (OPTIONAL)

When communicating with a TSC unit via the serial port, the data formats of both units must be identical. A print operation occurs when the user input, programmed for the print request function is activated, when a “P” command is sent via the serial communications port, or after the time expires for the automatic print rate,if enabled. Serial communication is covered in detail in the RS-485 SERIAL COMMUNICATIONS SECTION.

Baud Rate (bAUd)

The available baud rates are:

300, 600, 1200, 2400, 4800, or 9600

Parity Bit (PArb)

Parity can be odd, even, or no parity.

Address Number (Addr)

Multiple unitsconnected on the same RS-485 interface line musteach have a different address number.A value of 0 does not require the address specifier command, when communicating with the TSC. The address numbers range from 0 to 99.

Abbreviated or Full Transmission (Abrv)

When transmitting data, the TSC can be programmed to suppress the address number, mnemonics, units, and some spaces by selecting YES. An example of abbreviated and full transmission are shown below:

NO - 6 SET 123.8F<CR> <LF> Full Transmission

YES - 123.8<CR> <LF> Abbreviated Transmission

Print Rate (PrAt)

The TSC can be programmed to automatically transmit the selected print options at the programmed print rate. Selecting 0 disables the automatic print rate feature.

PrAt - 0 to 9999 seconds

Print Options (PoPt)

Selecting YESfor the printoptions will allow the operator to scroll through the available options using the PAR button. The up and down arrow keys toggle between “yes” and “no” with “yes” enabling the option to be printed when a print function occurs.

INP Print Input Temperature Value

SEt Print Setpoint Value

CONTROL POINTS MODULE (7-CP)

There are four Control Points, each having a setpoint value and an associated PIDgain set value. A control point canbe implemented at any time to accommodate changing process requirements due to batch changeover, level changes, etc.

The PIDgain set values (ProP, Int, & Dert) maybe optionally implemented with the setpoint value. A Control Point can be loaded from the hidden mode or by the user input (control points 1 and 2 only, see user input control point (CP) function).

The control point overwrites the previous setpoint and optionally the PID values. The unit begins controllingbased on thesenew values. Whena control point is loaded, the controller suppressesthe output ‘bump’usually associated with PID gain changes. Control points must be manually loaded and may be used in conjunction with a running profile.

Control Point Set-up (CSEt)

Select the control point to be configured.

NO CP-1 CP-2 CP-3 CP-4

Selecting NO returns the unit to the configuration access point.

Setpoint Value (SP-n)

Enter the temperature setpoint value for the selected control point. This value is constrained to the setpoint low (SPLO) and setpoint high (SPHI) range limits (see inputs configuration module).

SP-n - -999 to 9999

PID Values(PId)

Choose the option of loading the PID gain set values with setpoint value when implementing a Control Point.

NO - Disables PID entries and returns to control point set-up (CSEt).

YES - PID gain set is implemented when control point is loaded.

Enter the desired PID gain set values.

Pb-n - Proportional Band 0.0 to 999.9%

It-n - Integral Time 0 to 9999 secs

dt-n - Derivative Time 0 to 9999 secs

PROFILES MODULE (8-PR)

Prior to programming a profile, it is recommended to configure the basic controller operation. A profile is a series of one or more programmable ramp and hold phases. A minimum of three parameters are required for a profile:

Each profile can be programmed with up to eight ramp and hold phases. Associated with each profile is a timed event output set that updates as the profile advances. Additional parameters are provided which enhance the controller and profile capabilities.

Profile Set-Up

Select which profile or timed event output to program.

The programming parameters for each profile are the same. The operator programs eachphase and continues until all eight phasesare programmed or a ramp rate of -0.1 is entered. Shown below are the parameters for profile 1.

PROFILE

Profile Linking (PnLn)

Each profile can have up to eight ramp and eight hold phases programmed. If more than eight phases are required, profiles may be linked together. Linking allows the next profile to automatically start when the currentprofile has completed itscycle count. A single profilecan be expanded up to 32 ramp and hold phases of execution by linking.

P1Ln - Selecting YES links profile 1 to profile 2. P2Ln - Selecting YES links profile 2 to profile 3. P3Ln - Selecting YES links profile 3 to profile 4. P4Ln - Selecting YES links profile 4 to profile 1.

Profiles execute the prescribed number of cycle counts prior to linking to the next profile. A linked profile uses the last setpoint value of the previous profile asits starting point. The linkingparametercan be changed during profile operation.

Changes can be made to any profile parameter while the profile is running. Ramp rate, hold time, and setpoint level changes take effect as the profile advances. If a change is made to a phase that is active, the change is not recognized until the next time the profile is run.

From thenormal display mode,the phase time remaining and target setpoint value allow temporary changes to a running profile. These changes take effect immediately.

Profile Cycle Count (PnCC)

Once a profile is started, it runs the programmed number of cycles and then automatically defaults to the off mode. If this parameter is changed while the profile is running, the new value does not take effect until the profile is stopped (off mode). It is not possible to examine the number of profile cycle counts that a profile has completed. A cycle count value of0 prevents the profilefrom operating. A cycle count value of 250 allows continuous profile cycling.

PROFILE CYCLE COUNT & LINK FEATURES

Profile Power Cycle Status (PnSt)

Upon controller power-on, several profile operating modes exist. Each

profile has an independent power cycle status.

StOP - Stopplaces aprofile into the Offmode, regardless of the mode

prior to power down.

CONt - Continueresumes theoperation of a runningprofile (including

event output states) at the point where power was removed to the controller.

Strt - Start automatically re-starts a profile. This is useful for

automatic execution, soft-start profile at power-up, or automatic execution of a standard profile.

Power cycle status may be changed while a profile is running. The options of the power cycle status may create conflicts between one or more profiles. The priority structure for the power cycle status is:

Priority #1 -The profilethat was running andprogrammed for continue

resumes operation when power is restored.

Priority #2 - If the profile that was running prior to power down is

not programmed for continue, any profile programmed for start will re-start. Profile 1 has the highest priority.

Profile Error Band (PnEb)

Profile temperature conformity can be assured by using the profile Error Band parameter. If the process temperature deviates outside the error band value while a profile is running, the controller enters the delay mode. In the delay mode, the time base of the profile is held (delayed) until the process temperature is within the deviation error band. At this time, the profile continues running unless the process temperature again deviates. These actions assurethat the actual process temperatureconforms to the profile. The error band can be programmed for a positive or negative value which is expressed in degrees.

PnEb - -999 to 9999 degrees

A Positive Error Band value operates on hold phases only. This is useful when temperature soak time must be assured without affecting ramp phase time. A Negative ErrorBand value allows a profile to enter the delay mode on both ramp AND hold phases. This parameter may be altered during profile operation and the new values takes effect immediately. A value of 0 disables Error Band detection.

Ramp Phase (Pnrn)

The ramp phase is defined as automatic changing (ramping) of the setpoint value over a discrete time period at a predefined rate. The ramp rate is expressed in tenths of degree per minute.

Pnrn - 0.1 to 999.9 degrees/minute

The slope of the ramp phase (up or down) is automatically determined by the controller using the current setpoint value and target setpoint value. Upon starting a profile, the setpoint value begins ramping from the measured input temperature value to the target setpoint value. A profile can begin ramping from a defined setpoint level by entering 0.0 for the first ramp phase and 0.0 for the first hold phase. Entering 0.0 causes the profile to advance directly to the target setpoint value and begin the hold phase. This is known as a Step Ramp Phase. Timed Event outputs update at a Step Ramp Phase. The next ramp phase starts after the hold phase times-out.

A “staged” ramp approach is possible by using hold phase times of 0.0 minutes and redefining the new ramp rate(s).

STAGED RAMP & STEP RAMP PROFILE

Setpoint Value (PnLn)

The controller ramps to the Target Setpoint Value and then maintains the Target Setpoint Value over the hold phase time. The setpoint value is constrained to the setpoint limit values (SPLO & SPHI).

PnLn

-999 to 9999 degrees

Hold Phase (PnHn)

The controller maintains the target setpoint value constant during ahold phase for a fixed period of time. The hold phase is expressed in tenths of minutes.

0.1 to 999.9 minutes

Holds times longer than 999.9 minutes are possible by joining two or more hold phases. Hold phases are joined by setting the in-between ramp rate to 0.0, which skips the ramp phase.

A hold phase time value of 0.0 minutes skips the hold phase. Although Event Outputs assigned to that phase are updated. Two or more ramp phases (staged ramps) may be joined together by setting the in-between hold phase time to 0.0 minutes.

Timed Event Output(s) (Pn 1 to Pn 16)

The alarm channelscan be independently configured to operateas an Alarm Output or a Timed Event Output. The alarm(s) must be configured in the Alarm Module (4-AL). If configuredas an alarm,the output stateassignments are ignored.

Timed Event Outputs use AL1 and/or AL2 to signal or activate other equipment during execution of a profile. The Timed Event Outputs are updated at the start of each ramp and hold phase and remain defined for the duration of that phase. Front panel annunciators AL1 or AL2 light, if the Timed Event Output phase is programmed to activate the corresponding output. The table lists the four assignment choices for each phase:

Mnemonic Description

1F2F Alarm 1 off, Alarm 2 off

1F2N Alarm 1 off, Alarm 2 on

1N2F Alarm 1 on, Alarm 2 off

1N2N Alarm 1 on, Alarm 2 on

Each phase of the profile corresponds to an Event Output number. One of the output state assignments is programmed to each profile phase. The table lists the correspondence.

Description

Note: Each Timed Event Output number can be programmed to one of the

output states (1F2F, 1F2N, 1N2F, or 1N2N).

If using the Timed Event Outputs for Profile #4, and the other profiles are set for “Stop” operation, the unit will power-up with the outputs in an indeterminate state. To define the Timed Event Outputs under this condition, assign all of the Timed Event Outputs in Profile #4 to off.

-45-

Timed Event Output(s) (Pn 1 to Pn 16) (Cont’d)

It is possible to have the Event Outputs operate during profile phases by creating ‘phantom’ phases, whose sole function is to allow a new state of Event Outputs.

Each profile corresponds to a Timed Event Output.

The Event Output(s) may be manually reset to the off state at any time during profile execution. A timed event output may be reset via the user input (if programmed), the front panel buttons (in the hidden mode), or the RS-485 serial communication option.Once reset they remain inthat state until the profile advances to the next phase and the event output updates.

RS-485 SERIAL COMMUNICATIONS INTERFACE

RS-485 communicationsallows for transmitting and receiving of data over a single pair of wires.This optional featurecan be used for monitoring various values, resetting output(s), and changing values, all from a remote location. Typical devices that are connected to a TSC unit are a printer, a terminal, a programmable controller, or a host computer.

The RS-485 differential (balanced) design has good noise immunity and allows for communication distances of up to 4000 feet. Up to 32 units can be connected on a pair of wires and a common. The RS-485 common is isolated from the controller input signal common to eliminate ground loop problems associated with the input probe. The unit’s address can be programmedfrom 0 to 99. An Optional RLC Serial Converter Module (RS-422 to 20 mA current loop) can be installed to expand the unit’s flexibility.

COMMUNICATION FORMAT

The half-duplex communication operationsends data by switching voltage levels on the common pair of wires. Data is received by monitoring the levels and interpreting the codes that were transmitted.

In order for data to be interpreted correctly, there must be identical formats and baudrates between thecommunicating devices. The formats availablefor the TSC unit are 1 start bit, 7 data bits, No parity or 1 parity bit (odd or even) and 1 stop bit. The programmable baud rates are; 300, 600, 1200, 2400, 4800, or 9600 baud.

10 BIT DATA FORMAT

9 BIT DATA FORMAT

Before serial communication can take place, the unit must be programmed to the same baud rate and parity as the connected equipment. In addition, the loop address number and print options should be known. When used with a terminal or host computer and only one unit is employed, an address of zero (0) may be used to eliminate the requirement for the address specifier when sending a command. If more than one unit is on the line, each unit should be assigned a different address number.

SENDING COMMANDS AND DATA

When sending commands to a TSC unit, a command string must be constructed. The command string may consist of command codes, value identifiers, and numerical data. Below is a list of commands and value identifiers that are used when communicating with the TSC unit.

COMMAND DESCRIPTION

N (4EH) Address command; Followed by a one or two digit address number 0-99.

P (50H) Transmit print options command; Transmits the options selected in the

R (52H) Reset command; Followed by one of the Value Identifiers (G or H)

T (54H) Transmit value command; Followed by one of the Value Identifiers (A-M, O, Q).

C (43H) Control action command; Followed by the Value Identifier (S or U) and number.

V (56H) Change value command; Followed by one Value Identifier (B-H & J-M, O),

UNITS

Note: The % output power can be changed only if the controller is in the

manual mode of operation. Profile data cannot be configured via the serial interface. Only status changes can be made to a running profile.

Q The Auto Setpoint Ramp Rate is not associated with a profile. This

parameter is programmed in the Input Parameter Module (1-IN) (see Setpoint Ramp Rate for details).

A command string is constructed by using a command, a value identifier, and a data value if required. The Data value need not contain the decimal point since itis fixed within the unit, when programmed at thefront panel. The TSC will accept the decimal point, however it does not interpret them in any way. Leading zeros can be eliminated, but all trailing zeros must be present.

Example: If an alarm value of 750.0 is to be sent, the data value can be

transmitted as 750.0 or 7500. If a 750 is transmitted, the alarm value is

changed to 75.0 in the unit.

The address command allows a transmission string to be directed to a specific uniton the serial communications line. When the unit address is zero, transmission of the address command is not required. For applications that require several units,it is recommended thateach unit on theline be assigned a specific address.

If they are assigned the same address, a Transmit Value Command, will cause all the units to respond simultaneously, resulting in a communication collision.

The commandstring is constructed in aspecific logical sequence. The TSC does not accept command strings that do not follow this sequence. Only one operation can be performed per command string.

The following procedureshouldbe used whenconstructing a command string.

1. The first two to three characters of the command string must consist of the

Address Command (N)and the address numberof the unit (0-99). Ifthe unit

address is zero, the address command and number need NOT be sent.

2. The next character in the command string is the command that the unit is to

perform (P, R, T, C, or V).

3. A Value Identifier is next if it pertains to the command. The command P

(print) does not require a Value Identifier.

4. The numerical data will be next in the command string if the “Change

Value” or “Control Action” command is used.

5. All command strings must be terminated with an asterisk

Q (2AH). This

character indicates to the unit that the command string is complete and

begins processing the command.

Below are typical examples of command strings. Ex. 1 Change ProportionalBand Value to 13.0%on the unit with anaddress

of 2.

Command String: N2VD130

Ex. 2 Transmit the Temperature Value of the unit with an address of 3.

Command String: N3TA

Ex. 3 Reset Alarm Output 1 of the unit with an address of 0.

Command String: RG

Ex. 4 Start profile 1 of the unit with an address of 13.

Command String: Nl3CU1

If illegal commands or characters are sent to the TSC, the string must be re-transmitted.

SENDING COMMANDS AND DATA (Cont’d)

When writing application programs in Basic, the transmission of spaces or carriage return and line feed should be inhibited by using the semicolon delimiter with the “PRINT” statement. The unit does not accept a carriage return or line feed as valid characters.

It is recommended that a “Transmit Value” command follow a “Change Value” Command. If this is done, the reception of the data can provide a timing reference forsending another command andinsures that the change has occurred. When a “Change Value or Reset” command is sentto theunit, there is time required for the unit to process the command string. The diagrams show the timing considerations that need to be made.

RECEIVING DATA

Data is transmitted from the TSC when a “T” Transmit Value or a “P” Transmit Print Options command is sent to the unit via the serial port. Also, when theUser Input, programmed for the Print Request function, isactivated. The print rate features allows the selected print options to be transmitted at a programmable automatic rate via the serial port. The format for a typical transmission string with mnemonics is shown below:

The first two digits transmitted are the unit address followed by one blank space. If the unit address is 0, the first locations are blank. The next three characters are the mnemonics followed by one or more blank spaces. The numerical data value is transmitted next followed by the identifying units. Negative values are indicated by a “-” sign.

The decimal point position “floats” within the data field depending on the actual value it represents. The numeric data is right justified without leading zeros.

When a “T” command or print request is issued, the above character string is sent for each line of a block transmission. An extra <SP><CR><LF> is transmitted following the last line of transmission from a print request, to provide separation between print outs.

If abbreviated transmission is selected, just numeric data is sent. If abbreviated transmission is NOT selected, the unit transmits Mnemonics and the units.

-60-

If more than one string is transmitted, there is a 100 msec minimum to 200 msec maximum built-in time delay after each transmission string and after each block of transmission. When interfacingto a printer,sending mnemonics are usually desirable. Examples of transmissions are shown below:

1 TMP 500F<CR><LF>100 - 200 msec Mnemonics Sent

1 SET 525F<CR><LF>100 - 200 msec

1 PWR 20%<CR><LF><SP><CR><LF>100 - 200 msec

-673.5<CR><LF>100 - 200 msec NO Mnemonics Sent

The Print Options provide a choice of which TSC data values are to be transmitted. The TSC will transmit the Print Options when either the User Input, programmed for the print request function is activated, a “P” (Transmit Print Options) commandis sent to theTSC via the serial port,or the Automatic Print Rate is set for a specific time. The Print Options are programmed in the Serial Communications Module (6-SC) with the available options:

1. Print Display Temperature Value.

2. Print Setpoint Value.

3. Print % Output Power Value.

4. Print % Proportional Band Value.

5. Print Integral Time Value.

6. Print Derivative Time Value.

7. Print Alarm 1 Value.

8. Print Alarm 2 Value.

9. Print Deviation From Setpoint Value.

10. Print % Output Power Offset Value.

11. Print Setpoint Ramp Rate Value.

12. Print Cooling Relative Gain Value.

13. Print Cooling Deadband Value.

14. Print Profile Phase Time Remaining.

15. Print Profile Status.

SERIAL CONNECTIONS

When wiringthe terminal blockat the rear of theunit, refer tothe label with the terminal description for installing each wire in its proper location. It is recommended that shielded (screened) cable be used for serial communications. This unit meets the EMC specifications using Alpha #2404 cable or equivalent. There are higher grades of shielded cable, such as four conductor twisted pair, that offer an even higher degree of noise immunity. Only two transceiver wires and a common are needed.

The two data (transceiver) wires connect to the TX/RX(+) and TX/RX(-) terminals, appropriately.

The cable should consist of a shielded twistedpair and insome applications a signal ground may be required to establish a ground reference. The signal ground is required if the equipment does not have internal bias resistors connected to the RS-485 transceiver lines. The signal ground is connected at the RS-485 common of only one TSC unit to the RS-485 equipment. If necessary, the shield can be used as the signal ground.

The signal input common is isolated from the RS-485 common and the analog output “-” terminal.

Note: Do NOTconnect any of the commonstothe 4-20 mA output“-” terminal.

Connecting To A Host Terminal

Six TSC units are used to control a process in a plant. The TSC units are located at theproper location to optimizethe process. A communicationline is run to an industrial computer located in the production office. The drawing shows the line connection. Each TSC is programmed for a different address and are all programmed for the same baud rate and parity as the computer (ex 9600 baud, parity even).

An application program is written to send and receive data from the units

using the proper commands.

TROUBLESHOOTING SERIAL COMMUNICATIONS

If problems areencounteredwhen interfacing theTSC(s) and host device or

printer, the following check list can be used to help find a solution.

1. Check all wiring. Refer to the previous application examples and use them as a guide to checkyour serial communicationwiring. Proper polarity of all units and other peripherals must be observed.

2. If the TSC is connected to a “host computer”, device or printer, check to make sure thatthe computer ordevice is configured withthe same baud rate and communication format as the TSC. The communication format the TSC will accept is; 1 start bit, 7 data bits, no parity or 1 parity bit (odd or even), and 1 stop bit.

3. Check the TSC’s unit address. If the Address command is not used when transmitting a command to the TSC,the TSC’s addressmust be setto 0. See “Sending Commands & Data” section for command structure.

4. If two-way communications are to be established between the TSC and a computer, have the computer receive transmissions from the TSC first. Activating the User Input, programmed for the print request function, will initiate transmissions from the TSC.

5. When sendingcommands to the TSC, an asterisk*(2Ah) must terminate the command. After system power-up an asterisk must first be sent to clear the TSC input buffer.

6. In multiple unit configurations, make sure each unit has a different address other than zero.

7. If all of the above has been done, try reversing the polarity ofthe transceiver wires between the TSC(s) and the RS-485 interface card. Some cards have the polarity reversed.

PID CONTROL

PROPORTIONAL BAND

Proportional band is defined as the “band” of temperature the process changes to cause the percent output power to change from 0% to 100%. The band may or may not be centered aboutthe setpointvalue dependingupon the steady state requirements of the process. The band is shifted by manual offset or integral action(automatic reset) to maintainzero error. Proportionalband is expressed as percent of input sensor range.

(Ex. Thermocouple type T with a temperature range of 600°C is used and is

indicated in degreesC with aproportional band of5%. This yields aband of

600°Cx5%=30°C)

The proportional band should be set to obtain the best response to a disturbance while minimizing overshoot. Low proportional band settings (high gain) result in quick controller response at expense of stability and increased overshoot. Settings that are excessively low will produce continuous oscillations atsetpoint. High proportionalband settings (lowgain) results in a sluggish response with long periods of process “droop”. A proportional band of 0.0% forces the controller into ON/OFF control mode with its characteristic cycling at setpoint (see ON/OFF Control).

INTEGRAL TIME

Integral time is defined as the time, in seconds, in which the output due to integral action alone equals the output due to proportional action with a constant process error. As long as a constant error exists, integral action will “repeat” the proportional action every integral time. Integral action shifts the center point position of the proportional band to eliminate error in the steady state. The units of integral time are seconds per repeat.

Integral action(also known as “automatic reset”) changes the outputpower to bring the process tosetpoint. Integral timesthat are toofast (small times)do not allow the process to respond to the new output value and, in effect, “over compensate” which leads to an unstable process with excessive overshoot. Integral times that are too slow (large times) produce a response which is sluggish to eliminate steady state errors. Integral action may be disabled by setting the term to 0. If done so, the previous integral output power value is maintained to keep the output at a constant level.

-64-

INTEGRAL TIME (Cont’d)

If integral actionisdisabled (Automatic Reset),manual reset is available by modifying the output power offset (“OPOF” initially set to zero) to eliminate steady state errors. This parameter appears in unprotected parameter mode when integral time is set to zero. The controller has the feature to prevent integral action when operating outside the proportional band. This prevents “reset wind-up”.

Note: The Proportional band shift dueto integralaction may itself be “reset”

by temporarily setting the controller into the ON/OFF control mode

(proportional band =0).

DERIVATIVE TIME

Derivative time isdefined as the time,in seconds, in which theoutput due to proportional action alone equals the output due to derivative action with a ramping process error. As long as ramping error exists, the derivative action will be “repeated” by proportional action every derivative time. The units of derivative time are seconds per repeat.

Derivative action isused to shortenthe process responsetime and helps to stabilize the process byproviding an output based onthe rate of change of the process. In effect, derivative action anticipates where the process is headed and changes the output beforeit actually “arrives”. Increasing the derivative time helps to stabilize the response, but too much derivative time coupled

with noisy signal processes, may cause the output to fluctuate too greatly yielding poor control. None or too little derivative action usually results in decreased stability with higher overshoots. No derivative action usually requires awider proportional and slower integraltimes to maintain the same degree of stability as with derivative action. Derivative action is defeated by setting the time to zero.

OUTPUT POWER OFFSET (MANUAL RESET)

If the integral time is set to 0 (automatic reset is off), it may be necessary to modify the output power to eliminate errors in the steady state. The output power offset (OPOF) parameter will appear in the unprotected mode, if the integral time = 0. If integral action (automatic reset) is later invoked, the previous output power offset remains in effect.

PID ADJUSTMENTS

To aid in the adjustment of the PID parameters for improved process control, atemperature chart recorder is necessary to providea visual means of analyzing the process. Compare the actual process response to the PID response figures with a step change to the process. Make changes to the PID parameters in no more than 20% increments from the starting value and allow the processsufficient time to stabilize before evaluating the effects ofthe new parameter settings.

PROCESS RESPONSE EXTREMES

-66-

ON/OFF CONTROL

The controller can operate in the ON/OFF control mode by setting the proportional band = 0.0. The ON/OFF control hysteresis band (CHYS) parameter can be used to eliminate output chatter around setpoint. The cooling output can also be used in the ON/OFF control by setting the relative gain = 0.0

The phase of the control action can be reversed by the output control action parameter. ON/OFF control is usually characterized by significant temperature oscillations about the setpoint value. Large control hysteresis values makes the oscillations larger. ON/OFF control should only be usedwhere the constant oscillations have little effect on the process.

AUTO-TUNE

Auto-Tune is auser initiated function inwhich the controller automatically determines the optimum PID settings based upon the process characteristics. The desired temperature setpoint should be entered first. Auto-Tune may then be initiated at start-up, from setpoint, or at any other process temperature point. Auto-Tune may be invoked while a profile is running and after Auto-Tune is complete, the profile resumes operation.

After Auto-Tune is complete, the PID settings remain constantuntil user modified.As shown in the Auto-Tune Operation figure, Auto-Tune cycles the process ata control point 3/4 of the distance between the current process temperature where Auto-Tune was initiated and the temperature setpoint. The 3/4 control point was selected to reduce the chance of temperature overshoot at setpoint when Auto-Tuning at start-up. If Auto-Tuning from setpoint and temperature overshoot is unacceptable, place the controller in the user (manual) mode and reduce the power to lower the process temperature. Allow the temperature to stabilize and execute Auto-Tune from the lower temperature. After starting Auto-Tune, the secondary display indicates the current phase (Aut1, Aut2, Aut3, Aut4, & Aut5). If the controller remains in an Auto-Tune phase unusually long, the process or connections may be faulty. Auto-Tune may be terminated at any time without disturbing the previous PID constants. As an alternative to auto-tuning, the manual tuning procedure can be used to give satisfactory results.

Prior to initiatingAuto-Tune, it is essentialthat the controller beconfigured to the application. In particular, control hysteresis (CHYS) and Auto-Tune damping code (tcod) must be set in the Output Parameters section. Generally, control hysteresis of2-5degreesis adequate. Thedamping code maybe set to yield the response characteristics shown in the damping code figure.

AUTO-TUNE OPERATION FIGURE

-69-

AUTO-TUNE (Cont’d)

A damping code setting of 0 gives the fastest response with some overshoot,

and a code of 4 gives the slowest response with minimum overshoot.

For heat/cool systems, use a damping code of 1 or 2. On these systems, the relative cooling gain (Gan2) and heat/cool overlap (db-2) must be set by the user (the controller will not alter these parameters). (See Cooling section for adjustment of these parameters). During Auto-Tune, it is important that external load disturbancesbe minimized, and ifpresent, other zone controllers idled as these will have an effect on the PID constant determination. Keep in mind forlarge thermal systemswith long time constants, Auto-Tunemay take hours to complete.

DAMPING CODE FIGURE

Note: Actual responses may vary depending on the

process, step changes, etc.

To Initiate Auto-Tune:

Make sure that Auto-Tuning is enabled in parameter lockouts module. Place the controller into the normal display mode. Press PAR for 3 seconds from normal display mode. Scroll to “tUNE” by use of PAR, if necessary. Select “YES” and press PAR. Auto-Tune is initiated.

To Cancel Auto-Tune: (Old PID settings remain in effect).

A) Make sure that Auto-Tuning is enabled in parameter lockouts module.

Place the controller into the normal display mode. Press PAR for 3 seconds from normal display mode. Scroll to “tUNE” by use of PAR, if necessary. Select “NO” and press PAR. Auto-Tune canceled.

B) Or reset the controller by disconnecting AC power.

Note: If using the linear DC output for control, full power will be applied

(+100% OP1 or-100% OP2)regardless of the outputpower limit settings.

APPENDIX “A” - APPLICATION EXAMPLE

TSC Glass Tempering Application

A manufacturer ofglass items needs toanneal (temper) their productsto reduce the brittleness of the glass structure. The tempering process requires theglass to be heated and subsequently cooled at acontrolled rate to change the structure of the glass. Different tempering profiles are required for different types of glass products.

A TSC is employed to control the temperature profile of the annealing oven. Four different temperature profiles are stored in the controller. The 4-20 mA analog output option is utilized to cool the annealing oven during the cooldown ramp phases. An eventoutput is usedto quickly cool the oven at the end of the batch run (alarm 1). Alarm 2 is used to signal the operator whenever the temperature is outside the prescribed profile.

Note: Units equipped with the RS-485 option have different terminal

designators. See “OutputVariations with or withoutthe RS-485 Option”.

The programming for this profile is as follows:

OUTPUT LEAKAGE CURRENT

The AL1and AL2/OP2 outputs of the TSC have an RCNetwork (Snubber) on the Normally Open contacts. High energy noise spikes are generated whenever current through an inductive load (such as motors, solenoids or relay coils) is interrupted. This noise may interfere with the unit doing the switching and other nearby equipment causing erratic operation and accelerate relay contact wear.

The Snubber Network isspecifically designed with a capacitor and resistor connected in series and installed across relay contacts. The network will have a small amount of AC leakage current even when the TSC’s Relay Module is “off”. The leakagecurrent is 2.1 mA nominal ataline voltage of 120VAC,and

4.3 mA nominal at 240 VAC respectively. Leakage current may cause some loads to stay onor to turn on when the Relay Module is turned off. This would only occur in unusual applications (such as with a relay with unusually low holding current or an LED). The leakage current may be eliminated by disabling the snubber, however, doing so will degrade the EMC performance of the unit.

First determine which output is associated with the leakage current: either AL1 or AL2/OP2. Remove the Bezel Assembly from the case (see Removing Bezel Assembly,page 9). The snubbers are located on theOption PCB (on the right side of the unit when viewed from the front). The snubbers consist of a capacitor and aresistor. The two resistors arelocated along the upperrear edge of the Option PCB. They are green in color and have color code stripes of yellow, violet,black and gold. There will be markings on the PCB closeto the resistors that say “SNUB1” and “SNUB2” for AL1 and AL2/OP2 respectively. Usinga pair ofdiagonal cutters, cut both leads of the appropriate resistor andremove it fromthe unit. Be sure toremove the resistor for only the problem alarmchannel; leave the other channel’s snubber functional incase it is needed.

The above stated leakage currents are valid when using the Relay Module (OMD00000). The Triac Module (OMD00001) has it’s own built in snubber and will introduce additional leakage current into the circuit. The Triac Module has leakage current of 2.1 mA nominal at a line voltage of 120 VAC, and 4.3 mA nominal at 240 VAC.

Note: The Snubber Network will be in one of the two configurations shown at

right, depending on model ordered.

APPENDIX “D” - MANUAL TUNING

OPEN LOOP STEP RESPONSE METHOD

The Open Loop Step Response Method is a tuning procedure that does not induce processoscillations. This methodinvolves making a step change to the process and observing the process reaction. A strip paper recorder or other high resolution data logging equipment is required for this procedure. This procedure requires that all disturbances to the process are minimized because the data is influenced by these disturbances.

1) Connect a chart recorder to log temperature and set the paper speed

appropriate for the process.

2) Set the controller to manual (user) control mode.

3) Allow the process to stabilize (line out).

4) Make a step change of 10% or more in the controller output. It may be

necessary to increase the size of the step to yield a sufficient process

reaction curve.

5) Record the response of the process. Use the information from the table to

calculate the controller tuning values. The PID tuning parameters are

determined graphically from the Process Reaction Curve Figure. Draw a

vertical line at the moment the step change was made. Draw a line (labeled

tangent) through the process reaction curve at its maximum upward slope.

Extend this line to intersect the vertical line.

Example: From the Process reaction Curve

a = 30°, t = 300 sec, step = 10%, thermocouple range = 1700°F.

CLOSED LOOP CYCLING METHOD

An alternative to auto-tuning ismanual tuning. Thistuning method induces oscillations into the process in the same way as the controller’s auto-tune function. If oscillations are not acceptable, the open-loop tuning method can be used.

The following is a manual tuning procedure for determination of the PID control constants.

1. Connect a chart recorder to log temperature and set the paper speed

appropriate for the process.

2. Set the controller to automatic (auto) control mode.

3. Set proportional band to 999.9%. (maximum setting)

4. Set integral time and derivative time to 0 seconds.

5. Decrease proportionalband (increase controller gain) byfactors of two until

process just begins to oscillate and the oscillations are sustained. Make a

small change in setpoint to provide a stimulus for oscillations. Allow

adequate time for the process to respond. If oscillations appear to grow,

increase proportional band. Adjust the proportional band until steady

oscillations appear.

6. Note thepeak-to-peak amplitude of the cycle(a) in degrees and theperiod of

oscillation (t) in seconds.

APPENDIX “E” - CALIBRATION

Calibration Check

The instrument has been fully calibrated at the factory for ALL thermocouple and RTD types. If the unit appears to be indicating or controlling incorrectly, refer to the troubleshooting section before attempting this procedure.

If the controller is suspected of reading incorrectly, the instrument may be checked for indication accuracy without disturbing the factory calibration. The four parameters to be checked are: mV reading, thermocouple cold junction temperature, RTD ohms reading, and linear DC output. The following procedures are used for this purpose.

Note: Allow 1/2 hour warm-up with the controller in an upright position in

such a manner to allow adequate ventilation to the case before checking

these parameters.

mV Reading Check

1) Place the input sensor selection jumper in the TC position.

2) Connect aDC mV sourcewith an accuracy of0.01% or betterto terminal #9

(+) & #10 (-).

3) Select the controller to indicate linear mV (LIN), in configure input

parameters.

4) Compare the controller readout to the standard at various points over the

range (-5.00 mV to 54.00 mV).

The tolerance is 0.15% of reading±1LSD

5) Calibrate the controller if the readings are out of tolerance.

Thermocouple Cold Junction Temperature Check

1) Place the input sensor selection jumper in the TC position.

2) Place a reference temperature probe in immediate vicinity of terminal #9

& #10.

3) Install a shorting wire to terminals #9 & #10.

4) With thermocouple type T selected, compare controller readout with a

calibrated probe. Allow sufficient time for temperatures to equalize. The

tolerance is ±1°C.

5) Calibrate the cold junction temperature if out of tolerance.

1) Place the input sensor jumper in the RTD position.

2) ConnectRTD simulator to terminals #8, #9, (with an accuracy of 0.1 ohm or better).

3) Select the controller for linear OHMS (rLIN) readout, in configure input parameters.

4) Compare the controller readout with the RTD simulator at various points over the range 0.0 to 300.0 ohms. The tolerance is 0.15% of reading ± 1 LSD.

5) Calibrate the controller RTD ohms if out of tolerance.

4to20mA

1) Connect an ammeter to the linear output (#11 & #12) with an accuracy of

0.1% or better.

2) Set “ANAS”(analog assignment)to “INP”, in configureinput parameters.

3) Drive the input signal level below the programmed “ANLO” value. Check for 4 mA (±0.02 mA).

4) Drive the input signal level above the programmed “ANHI” value. Check for 20 mA (±0.03 mA).

5) Calibrate the controller linear DC output if out of tolerance.

0to10VDC

1) Connect a voltmeter to the linear output (#11 & #12).

2) Set “ANAS”(Analog Assignment) to “INP”,inConfigure Input Parameters.

3) Drive the input signal level below the programmed “ANLO” value. Check for 0 VDC (±20 mV).

4) Drive the input signal level above the programmed “ANHI” value. Check for 10 VDC (±30 mV).

5) Calibrate the controller linear DC output if out of tolerance.

CALIBRATION

When calibration is required(generally everytwo years), this procedure should only be performed by qualified technicians using appropriateequipment. Equipment source accuracies of 0.01% or better are required.

The procedure consists of four parts: applying accurate mV signals, setting the thermocouple cold junction temperature, applying precision resistances and measuring accurate mA currents. Allow a 30 minute warm-up period before starting this procedure. Do not use thermocouple wire at any stage of calibration.

This procedure may be aborted by disconnecting power to the controller before exiting the configuration mode. The existing calibration settings remain in affect.

Note: Aftercompleting any of the calibrationsequences, the

controller will default the input sensor type to

thermocouple type “j” (tc-j). Be sure to set input sensor

for proper type.
