The software allows downloading, uploading and storage of T16 and P16 program files. All controllers have a communications port that allows configuration by PC even without controller power connected. Controller calibration is also possible using the software when the proper calibration equipment and controller power is connected. The Model T16 Controller accepts signals from a variety of temperature sensors (thermocouple or RTD), while the Model P16 Controller accepts either a 0 to 10 VDC or 0/4 to 20 mA DC input signal. Both controllers can provide an accurate output control signal (time proportional or DC Analog Output) to maintain a process at a setpoint value. Dual 4-digit displays allow viewing of the process/temperature and setpoint simultaneously. Front panel indicators inform the operator of the controller and output status. The comprehensive programming allows these controllers to meet a wide variety of application requirements. CONSTRUCTION The controller is constructed of a lightweight, high impact, black plastic textured case and bezel with a clear display window. The front panel meets NEMA 4X/IP65 specifications when properly installed. In applications that do not require protection to NEMA 4X, multiple controllers can be stacked horizontally or vertically. Modern surface-mount technology, extensive testing, plus high immunity to noise interference makes the controller extremely reliable in industrial environments. MAIN CONTROL The controller operates in the PID Control Mode for both heating and cooling, with on-demand auto-tune, that establishes the tuning constants. The PID tuning constants may be fine-tuned through the front panel and then locked out from further modification. The controller employs a unique overshoot suppression feature, that allows the quickest response without excessive overshoot. Switching to Manual Mode provides the operator direct control of the output. The controller may also be programmed to operate in On/Off mode with adjustable hysteresis. SAFETY SUMMARY All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Do not use the controller to directly command motors, valves, or other actuators not equipped with safeguards. To do so can be potentially harmful to persons or equipment in the event of a fault to the controller. An independent and redundant temperature limit indicator with alarm outputs is strongly recommended. ALARMS Optional alarm(s) can be configured independently for absolute high or low acting with balanced or unbalanced hysteresis. They can also be configured for deviation and band alarm. In these modes, the alarm trigger values track the setpoint value. Adjustable alarm hysteresis can be used for delaying output response. The alarms can be programmed for Automatic or Latching operation. A selectable standby feature suppresses the alarm during power-up until the temperature stabilizes outside the alarm region. ANALOG OUTPUT OPTION The optional DC Analog Output (10 V or 20 mA) can be configured and scaled for control or re-transmission purposes. The programmable output update time reduces valve or actuator activity. CAUTION: Risk of Danger. Read complete instructions prior to installation and operation of the unit. CAUTION: Risk of electric shock.

The following EMI suppression devices (or equivalent) are recommended: Fair-Rite part number 0443167251 (Red Lion Controls #FCOR0000) Line Filters for input power cables: Schaffner # FN2010-1/07 (Red Lion Controls #LFIL0000) 6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life. b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most Red Lion products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used. Red Lion part numbers: Snubber: SNUB0000 Varistor: ILS11500 or ILS23000 7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation. Although Red Lion Controls products are designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment. 1. A unit should be mounted in a metal enclosure, which is properly connected to protective earth. 2. Use shielded cables for all Signal and Control inputs. The shield connection should be made as short as possible. The connection point for the shield depends somewhat upon the application. Listed below are the recommended methods of connecting the shield, in order of their effectiveness. a. Connect the shield to earth ground (protective earth) at one end where the unit is mounted. b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1 MHz. 3. Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors, feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components. 4. Long cable runs are more susceptible to EMI pickup than short cable runs. 5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is Visit http://www.redlion.net/emi for more information on EMI guidelines, Safety and CE issues as they relate to Red Lion products. 4 1.0 Setting the Jumpers To insure proper operation, the Analog Output jumpers must be set to the same range selected in programming Module 2-OP. The default jumper setting is for 20 mA. The default setting in Module 2-OP is 4-20 mA. To access the jumpers, insert a flat-blade screwdriver between the front panel and the side case slot. This should disengage the top and bottom front panel latches from the case grooves. Pull the front panel assembly with the controller boards out of the case. The jumpers are located inside the controller on the left board along the back top section. RDY A1 A2 01 02 F1 (Analog Output Models Only) LS RED RK, YO TRO ON N C .S.A. LIO DE MA PA.

The controllers are designed to be PANEL GASKET mounted into an enclosed panel. The bezel assembly must be in place during installation of BEZEL the controller. PANEL 13 14 6 7 PANEL MOUNTING SCREW LATCHING TABS 8 9 10 LATCHING SLOTS PANEL LATCH Instructions: 1. Prepare the panel cutout to the proper dimensions. 2. Remove the panel latch from the controller. Discard the cardboard sleeve. 3. Carefully remove the center section of the panel gasket and discard. Slide the panel gasket over the rear of the controller, seating it against the lip at the front of the case. 4. Insert the controller into the panel cutout. While holding the controller in place, push the panel latch over the rear of the controller, engaging the tabs of the panel latch in the farthest forward slot possible. 5. To achieve a proper seal, tighten the panel latch screws evenly until the controller is snug in the panel, torquing the screws to approximately 7 in-lb (79 N-cm). Overtightening can result in 1.772 +0.024 -0.000 distortion of the controller, and reduce the (45 +0.6 ) effectiveness of the seal. -0.0 Note: The installation location of the controller is important. Be sure to keep it away from heat sources (ovens, furnaces, etc.) and away from 1.772 +0.024 direct contact with caustic vapors, oils, steam, or -0.000 any other process by-products in which exposure (45 +0.6 -0.0 ) may affect proper operation. Multiple Controller Stacking 2.39 (60.7) MAX. The controller is designed to allow for close spacing of multiple controllers in applications that do not require protection to NEMA 4X. Controllers can be stacked either horizontally or vertically. For vertical stacking, install the panel latch with the screws to the sides of the controller. For horizontal stacking, the panel latch screws should be at the top and bottom of the controller. The minimum spacing from centerline to centerline of controllers is 1.96" (49.8 mm). This spacing is the 1.96 (49.8) same for vertical or MIN horizontal stacking. Note: When stacking controllers, provide adequate panel ventilation to ensure that the maximum operating temperature range is not exceeded. 1.96 (49.8) MAX 1.96 (49.8) MAX. 2.39 (60.7) MAX STANDARD PANEL CUT-OUT IF NEMA 4 IS NOT REQUIRED, THIS PANEL MATERIAL MAY BE REMOVED. 5 3.0 Wiring the Controller WIRING CONNECTIONS codes and regulations. It is recommended that power (AC or DC) supplied to the controller be protected by a fuse or circuit breaker. Strip the wire, leaving approximately 1/4" (6 mm) bare wire exposed (stranded wires should be tinned with solder). Insert the wire under the clamping washer and tighten the screw until the wire is clamped tightly. All wiring connections are made to the rear screw terminals. When wiring the controller, use the numbers on the label and those embossed on the back of the case, to identify the position number with the proper function. All conductors should meet voltage and current ratings for each terminal. Also, cabling should conform to appropriate standards of good installation, local VDC CONTROLLER POWER CONNECTIONS For best results, the power should be relatively “clean” and within the specified limits. Drawing power from heavily loaded circuits or from circuits that also power loads that cycle on and off should be avoided. It is recommended that power supplied to the controller be protected by a fuse or circuit breaker.

A temperature offset error will exist. The error may be compensated by programming a temperature offset. For two wire RTDs, install a copper sense lead of the same gauge and length as the RTD leads. Attach one end of the wire at the probe and the other end to input common terminal. Complete lead wire compensation is obtained.

Display Loop parameters may be locked out or hidden in Lockout Module 3-LC. Some parameters are model and programming dependent. At power up, all display segments light, and then the programmed input type and the controller’s software version will flash. Then the Temperature/Process Value is shown in the top display, and the Setpoint Value is shown in the bottom display. This is the Display Loop. If the Setpoint is hidden or locked, the Display Loop will default to Output Power. If Output Power is also hidden or locked out, the bottom display is blank.

The value is either absolute (absolute alarm types) or relative to the Setpoint value (deviation and band alarm types.) When Alarm 2 is programmed for  or , this parameter is not available. For more details on alarms, see the Alarm Module . When the Integral Time is set to zero and the controller is in the Automatic Mode, this parameter will appear after % Output Power. It is also shown with the %PW annunciator illuminated. The power offset is used to shift the proportional band to compensate for errors in the steady state. If Integral Action is later invoked, the controller will re-calculate the internal integral value to provide “bumpless” transfer and Output Power Offset will not be necessary. PROPORTIONAL BAND     T16 On models with alarms, the value for Alarm 1 can be entered here. The value is either absolute (absolute alarm types) or relative to the Setpoint value (deviation and band alarm types.) When Alarm 1 is programmed for  or , this parameter is not available.

Note: Parameters shown bold are the only parameters visible in the Hidden Loop with Factory Settings. Setpoint and Output Power are factory set for the Display Loop. The remaining parameters can be selected for the Hidden Loop within Module 3. Parameter availability is model and programming dependent.

HIDDEN LOOP When A is pressed and held for three seconds, the controller advances to the Hidden Loop. The Temperature/Process Value is shown in the top display. The bottom display alternates between the parameter and its selection/value. B or J is pressed to change the selection/value for the shown parameter. The new selection/value is activated after A is pressed. When L is pressed, the controller returns to the Display Loop and stores changed selection/values to permanent memory. Hidden Loop parameters may be locked out in Lockout Module . Some parameters are model and programming dependent. SETPOINT RAMP RATE     The setpoint ramp rate can reduce sudden shock to the process and reduce overshoot on startup or after setpoint changes, by ramping the setpoint at a controlled rate. R annunciator flashes while ramping. With the T16, the ramp rate is always in tenths of degrees per minute, regardless of the resolution chosen for the process display. With the P16, the ramp rate is in least-significant (display units) digits per minute. A value of 0.0 or 0 disables setpoint ramping. Once the ramping setpoint reaches the target setpoint, the setpoint ramp rate disengages until the setpoint is changed again. If the ramp value is changed during ramping, the new ramp rate takes effect. If the setpoint is ramping prior to starting AutoTune, the ramping is suspended during Auto-Tune and then resumed afterward. Deviation and band alarms are relative to the target setpoint, not the ramping setpoint. A slow process may not track the programmed setpoint rate. At power up, the ramping setpoint is initialized at the ambient temperature/process value. ACCESS CODE      to  If the Access Code is set from 1 to 125, in Lockout Module 3-LC, Access Code will appear here. By entering the proper Code, access to the Hidden Loop is permitted.

In Manual/User  Mode, the percentage of Output Power is adjusted manually while in the Display Loop. The Control Mode can also be transferred through the F1 Key or User Input. For more information, see Control Mode Explanations. The SPSL function allows the operator to switch from or to, setpoint 1 and setpoint 2. In the Display Loop, there is no annunciator indicating the selected Setpoint, however, the selected Setpoint value is displayed and activated. 9 AUTO-TUNE START     ACCESS CODE       The Auto-Tune procedure of the controller sets the Proportional Band, Integral Time, Derivative Time, Digital Filter, Control Output Dampening Time, and Relative Gain (Heat/Cool) values appropriate to the characteristics of the process. This parameter allows front panel starting  or stopping  of Auto-Tune. For more information, see PID Tuning Explanations. If the Access Code is set from -1 to -125, in Lockout Module , Access Code will appear here. By entering the proper Code, access to the Configuration Loop is permitted (with a negative Code value, the Hidden Loop can be accessed without the use of a code). With the factory setting of 0 or with an active User Input configured for Program Lock (), Access Code will not appear here. An active user input configured for Program Lock () always locks out the Configuration Loop, regardless of Access Code.

Increasing the value increases the dampening effect. Generally, dampening times in the range of one-twentieth to one-fiftieth of the controller’s integral time (or process time constant) are effective. Dampening times longer than these may cause controller instability due to the added lag effect. This determines the control action for the PID loop. Programmed for direct action (cooling), the output power will increase if the Process value is above the Setpoint value. Programmed for reverse action (heating), the output power decreases when the Process Value is above the Setpoint Value. For heat and cool applications, this is typically set to reverse. This allows O1 or A1 (models with Analog Output) to be used for heating, and A2/O2 to be used for cooling.

The On/Off Control Hysteresis (balanced around the setpoint) eliminates output chatter. In heat/cool applications, the control hysteresis value affects both Output O1 and Output O2 control. It is suggested to set the hysteresis band to Factory Setting prior to starting Auto-Tune. After Auto-Tune, the hysteresis band has no effect on PID Control. On/Off Control Hysteresis is illustrated in the On/Off Control Mode section. This parameter may be used to limit controller power at the lower end due to process disturbances or setpoint changes. Enter the safe output power limits for the process. If Alarm 2 is selected for cooling, the range is from -100 to +100%. At 0%, both O1 and O2 are off; at 100%, O1 is on; and at -100%, O2 is on. When the controller is in Manual Control Mode, this limit does not apply.

If Alarm 2 is not selected for cooling, the range is from 0% (O1 output full off) to 100% (O1 output full on). If A2 is selected for cooling, the range is from -100 to +100%. At 0%, both O1 and O2 are off; at 100%, O1 is on; and at -100%, O2 is on. The alarm outputs are upscale drive with an open sensor, and downscale drive with a shorted sensor (RTD only), independent of this setting. Manual Control overrides the sensor fail preset. The Cycle Time is entered in seconds with one tenth of a second resolution. It is the total time for one on and one off period of the time proportioning control output O1. With time proportional control, the percentage of power is converted into an output on-time relative to the cycle time value set. (If the controller calculates that 65% power is required and a cycle time of 10.0 seconds is set, the output will be on for 6.5 seconds and off for 3.5 seconds.) For best control, a cycle time equal to one-tenth or less, of the natural period of oscillation of the process is recommended. When using the Analog Output signal for control, the Cycle Time setting has no effect. If the O1 output is not being used, a cycle time of 0 can be entered to prevent the output and indicator from cycling.   ANALOG OUTPUT ASSIGNMENT SENSOR FAIL POWER LEVEL CYCLE TIME   ANAS ANALOG OUTPUT RANGE AUTO-TUNE CODE  to  percent O1  to  percent O1/O2   This parameter may be used to limit controller power at the upper end due to process disturbances or setpoint changes.

When the controller is in Manual Control Mode, this limit does not apply.  fastest to  slowest Prior to starting Auto-Tune, this code should be set to achieve the necessary dampening level under PID Control. This value allows customization of the PID values that Auto-Tune will calculate. For the process to be controlled aggressively (fastest process response with possible overshoot), set the Auto-Tune Code to 0. For the process to be controlled conservatively (slowest response with the least amount of overshoot), set this value to 2. If the Auto-Tune Code is changed, Auto-Tune needs to be reinitiated for the changes to affect the PID settings.

ALARM VALUE ALARM 1    Standby on  Standby off Standby prevents nuisance (typically low level) alarms after a power up or setpoint change. After powering up the controller or changing the setpoint, the process must leave the alarm region (enter normal non-alarm area of operation). After this has occurred, the standby is disabled and the alarm responds normally until the next controller power up or setpoint change.

(For P16 Controllers, the cooling output is sometimes referred to as secondary output.) When set to cooling, the output no longer operates as an alarm but operates as a cooling output. The O2 terminals are the same as A2, however a separate O2 annunciator indicates Cooling Operation. Cooling output power ranges from -100% (full cooling) to 0% (no cooling, unless a heat/cool overlap is used). The Power Limits in Output Module 2-OP also limit the cooling power. In applications requiring only a Cooling output, the main 01 output should be used. DEADBAND/OVERLAP    to  This defines the overlap area in which both heating and cooling are active (negative value) or the deadband area between the bands (positive value). If a heat/cool overlap is specified, the percent output power is the sum of the heat power (O1) and the cool power (O2). If Relative Gain is zero, the cooling output operates in the On/Off Control Mode, with the On/Off Control Hysteresis  in Output Module  becoming the cooling output hysteresis. The function of Deadband is illustrated in the Control Mode Explanations. For most applications, set this parameter to 0.0 prior to starting Auto-Tune. After the completion of Auto-Tune, this parameter may be changed. CYCLE TIME   CNFP  to  seconds This cycle time functions like the O1 Output Cycle Time but allows independent cycle time for cooling. A setting of zero will keep output O2 off. RELATIVE GAIN    to  This defines the gain of the cooling relative to the heating. It is generally set to balance the effects of cooling to that of heating. This is illustrated in the Heat/ Cool Relative Gain Figures. A value of 0.0 places the cooling output into On/ Off Control.

Recalibration is recommended every two years by qualified technicians using appropriate equipment. Calibration may be performed by using the front panel or with the TP16KIT. The front panel method is explained below. (Refer to the TP16KIT bulletin for calibration instructions using TP16KIT cable and software.) Calibration may be aborted by disconnecting power to the controller before exiting Factory Service Module . In this case, the existing calibration settings remain in effect. Note: Allow the controller to warm up for 30 minutes minimum and follow the manufacturer’s warm-up recommendations for the calibration source or measuring device.

In this control mode, the process will constantly oscillate around the setpoint value. The On/Off Control Hysteresis (balanced around the setpoint) can be used to eliminate output chatter. Output O1 Control Action can be set to reverse for heating (output on when below the setpoint) or direct for cooling (output on when above the setpoint) applications.

CHYS db-2 SP For heat and cool systems, O1 Control Action is set to reverse (heat) and the Alarm 2 Action is set to cooling (O2). The Proportional Band is set to 0.0 and the Relative Gain in Cooling to 0.0. The Deadband in Cooling sets the amount of operational deadband or overlap between the outputs. The setpoint and the On/Off Control Hysteresis applies to both O1 and O2 outputs. The hysteresis is balanced in relationship to the setpoint and deadband value. SP - 1/2 (db-2) + 1/2 CHYS SP - 1/2 (db-2) SP - 1/2 (db-2) - 1/2 CHYS CHYS Output 1 (O1) : Output 2 (O2) : PID CONTROL O1 ON O2 ON O2 OFF O1 OFF O1 ON O2 ON TYPICAL PID RESPONSE CURVE In PID Control, the controller processes the input and then calculates a control output power value by use of a modified Proportional Band, Integral Time, and Derivative Time control algorithm. The system is controlled with the new output power value to keep the process at the setpoint. The Control Action for PID Control can be set to reverse for heating (output on when below the setpoint) or direct for cooling (output on when above the setpoint) applications. For heat and cool systems, the heat (O1) and cool (O2) outputs are both used. The PID parameters can be established by using Auto-Tune, or they can be Manually tuned to the process. P&I P&I&D INPUT SP P&D P only TIME 21 TIME PROPORTIONAL PID CONTROL MANUAL CONTROL MODE In Time Proportional applications, the output power is converted into output On time using the Cycle Time. For example, with a four second cycle time and 75% power, the output will be on for three seconds (4 × 0.75) and off for one second. The cycle time should be no greater than 1/10 of the natural period of oscillation for the process. The natural period is the time it takes for one complete oscillation when the process is in a continuously oscillating state. In Manual Control Mode, the controller operates as an open loop system (does not use the setpoint and process feedback). The user adjusts the percentage of power through the % Power display to control the power for Output O1. When Alarm 2 is configured for Cooling (O2), Manual operation provides 0 to 100% power to O1 (heating) and -100 to 0% power to O2 (Cooling). The Low and High Output Power limits are ignored when the controller is in Manual. MODE TRANSFER LINEAR PID CONTROL When transferring the controller mode between Automatic and Manual, the controlling outputs remain constant, exercising true “bumpless” transfer. When transferring from Manual to Automatic, the power initially remains steady, but Integral Action corrects (if necessary) the closed loop power demand at a rate proportional to the Integral Time. In Linear PID Control applications, the Analog Output Assignment  is set to % Output Power, . The Analog Low Scaling,  , is set to 0.0 and the Analog High Scaling,  , is set to 100.0. The Analog Output will then be proportional to the PID calculated % output power for Heat or Cooling per the Control Action . For example, with 0 VDC to 10 VDC (scaled 0 to 100%) and 75% power, the analog output will be 7.5 VDC. AUTOMATIC CONTROL MODE In Automatic Control Mode, the percentage of output power is automatically determined by PID or On/Off calculations based on the setpoint and process feedback. For this reason, PID Control and On/Off Control always imply Automatic Control Mode. Pid Tuning Explanations AUTO-TUNE INPUT Auto-Tune is a user-initiated function that allows the controller to automatically determine the Proportional Band, Integral Time, Derivative Time, Digital Filter, Control Output Dampening Time, and Relative Gain (Heat/Cool) values based upon the process characteristics. The Auto-Tune operation cycles the controlling output(s) at a control point three-quarters of the distance between the present process value and the setpoint. The nature of these oscillations determines the settings for the controller’s parameters. Prior to initiating Auto-Tune, it is important that the controller and system be first tested. (This can be accomplished in On/Off Control or Manual Control Mode.) If there is a wiring, system or controller problem, Auto-Tune may give incorrect tuning or may never finish. Auto-Tune may be initiated at start-up, from setpoint or at any other process point. However, ensure normal process conditions (example: minimize unusual external load disturbances) as they will have an effect on the PID calculations. AUTO-TUNE CODE FIGURE SP 2 1 0 TIME Start Auto-Tune Below are the parameters and factory settings that affect Auto-Tune. If these setting are acceptable then Auto-Tune can be started just by performing two steps. If changes are needed, then they must be made before starting Auto-Tune.

Auto-Tune Progress The controller will oscillate the controlling output(s) for four cycles. The bottom display will flash the cycle phase number. Parameter viewing is permitted during Auto-Tune. The time to complete the Auto-Tune cycles is process dependent. The controller should automatically stop Auto-Tune and store the calculated values when the four cycles are complete. If the controller remains in Auto-Tune unusually long, there may be a process problem. AutoTune may be stopped by entering  in Auto-Tune Start . 22 PID Adjustments In some applications, it may be necessary to fine tune the Auto-Tune calculated PID parameters. To do this, a chart recorder or data logging device is needed to provide a 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 process sufficient time to stabilize before evaluating the effects of the new parameter settings. In some unusual cases, the Auto-Tune function may not yield acceptable control results or induced oscillations may cause system problems. In these applications, Manual Tuning is an alternative. PROCESS RESPONSE EXTREMES OVERSHOOT AND OSCILLATIONS SLOW RESPONSE INPUT INPUT SP SP TIME TIME TO DAMPEN RESPONSE: - INCREASE PROPORTIONAL BAND. - INCREASE INTEGRAL TIME. - USE SETPOINT RAMPING. - USE OUTPUT POWER LIMITS. - RE-INVOKE AUTO-TUNE WITH A HIGHER AUTO-TUNE CODE. - INCREASE DERIVATIVE TIME. - CHECK CYCLE TIME. TO QUICKEN RESPONSE: - DECREASE PROPORTIONAL BAND. - DECREASE INTEGRAL TIME. - INCREASE OR DEFEAT SETPOINT RAMPING. - EXTEND OUTPUT POWER LIMITS. - RE-INVOKE AUTO-TUNE WITH A LOWER AUTO-TUNE CODE. - DECREASE DERIVATIVE TIME. MANUAL TUNING A chart recorder or data logging device is necessary to measure the time between process cycles. This procedure is an alternative to the controller’s AutoTune function. It will not provide acceptable results if system problems exist. 1. Set the Proportional Band () to 10.0% for temperature models (T16) and 100.0% for process models (P16). 2. Set both the Integral Time () and Derivative Time () to 0 seconds. 3. Set the Output Dampening Time () in Output Module  to 0 seconds. 4. Set the Output Cycle Time [CYCt] in Output Module  to no higher than one-tenth of the process time constant (when applicable). 5. Place the controller in Manual  Control Mode  in the Hidden Loop and adjust the % Power to drive the process value to the Setpoint value. Allow the process to stabilize after setting the % Power. Note:  must be set to  in Parameter Lockouts Module . 6. Place the controller in Automatic () Control Mode  in the Hidden Loop. If the process will not stabilize and starts to oscillate, set the Proportional Band two times higher and go back to Step 5. 7. If the process is stable, decrease Proportional Band setting by two times and change the Setpoint value a small amount to excite the process. Continue with this step until the process oscillates in a continuous nature. 8. Fix the Proportional Band to three times the setting that caused the oscillation in Step 7. 9. Set the Integral Time to two times the period of the oscillation. 10. Set the Derivative Time to 1/8 (0.125) of the Integral Time. 11. Set the Output Dampening Time to 1/40 (0.025) the period of the oscillation. 23 PARAMETER VALUE CHART Programmer:______________________Date:_________ Controller Number:_______ Security Code:_______ DISPLAY LOOP DISPLAY PARAMETER  SETPOINT VALUE SP1    * SETPOINT VALUE SP2  OUTPUT POWER PERCENT PROPORTIONAL BAND * INTEGRAL TIME  *  *  * DERIVATIVE TIME ALARM 1 VALUE ALARM 2 VALUE OUTPUT MODULE () FACTORY SETTING USER SETTING DISPLAY  T16  P16  T16  P16   T16  P16  T16  P16  T16  P16   * Factory Setting places these parameters in the Hidden Loop (set to Lockout Module .  in PARAMETER       CYCLE TIME        ON/OFF CONTROL HYSTERESIS CONTROL ACTION OUTPUT POWER LOWER LIMIT OUTPUT POWER UPPER LIMIT SENSOR FAIL POWER PRESET OUTPUT POWER DAMPENING AUTO-TUNE CODE ANALOG OUTPUT RANGE ANALOG OUTPUT ASSIGNMENT ANALOG UPDATE TIME ANALOG LOW SCALING ANALOG HIGH SCALING FACTORY SETTING USER SETTING       T16  P16  T16  P16 0      HIDDEN LOOP DISPLAY     PARAMETER FACTORY SETTING SETPOINT SELECT LOCKOUT MODULE () USER SETTING     SETPOINT RAMP RATE CONTROL MODE TRANSFER AUTO-TUNE START DISPLAY           INPUT MODULE ( ) T16 ONLY DISPLAY          PARAMETER FACTORY SETTING INPUT TYPE USER SETTING j         TEMPERATURE SCALE DECIMAL RESOLUTION DIGITAL FILTERING SHIFT/OFFSET SETPOINT LOW LIMIT SETPOINT HIGH LIMIT USER INPUT FUNCTION F1 KEY FUNCTION              PARAMETER INPUT TYPE PERCENT ANNUNCIATOR DECIMAL RESOLUTION ROUNDING INCREMENT DIGITAL FILTERING DISPLAY VALUE SCALING 1 INPUT VALUE SCALING 1 DISPLAY VALUE SCALING 2 INPUT VALUE SCALING 2 SETPOINT LOW LIMIT SETPOINT HIGH LIMIT USER INPUT FUNCTION F1 KEY FUNCTION FACTORY SETTING SETPOINT ACCESS OUTPUT POWER ACCESS PID VALUE ACCESS ALARM VALUE ACCESS ACCESS CODE SETPOINT SELECT ACCESS SETPOINT RAMP ACCESS TRANSFER CONTROL ACCESS AUTO-TUNE ACCESS RESET ALARMS ACCESS FACTORY SETTING USER SETTING           ALARM MODULE () DISPLAY            INPUT MODULE ( ) P16 ONLY DISPLAY PARAMETER USER SETTING            PLOC NONE PARAMETER ALARM 1 ACTION ALARM 1 ANNUNCIATOR ALARM 1 RESET MODE ALARM 1 STANDBY ALARM 1 VALUE ALARM 2 ACTION ALARM 2 ANNUNCIATOR ALARM 2 RESET MODE ALARM 2 STANDBY ALARM 2 VALUE ALARM 1 & 2 HYSTERESIS FACTORY SETTING USER SETTING         NO   T16  P16 COOLING MODULE () DISPLAY    24 PARAMETER CYCLE TIME RELATIVE GAIN DEADBAND FACTORY SETTING    USER SETTING 25 9-FS 5-O2 4-AL 3-LC 2-OP 1-IN CNFP   no HIDDEN LOOP Factory Service Code CodE Cooling Cycle Time CYC2 Alarm 1 Action ACt1 Setpoint Access Ends and returns to start of Display Loop.
