9215 1 INTRODUCING THE SETPOINT PROGRAMMER The Setpoint Programmer is a powerful, easy-to-use 14-DIN instrument with full PID control capability (complete with Self-Tune/Pre-Tune facilities). Its standard features are: * Up to eight programs of up to 16 free-format (e.g. dwell, ramp, join or end) segments each. * Facility to join programs to one another in any sequence (maximum program length 121 segments). * User can change currently-running program segment.
59215 The Setpoint Programmer has four operating modes: Base Mode: Day-to-day PID control operations with no program running. In this mode, a program may be selected to run. Program Run Mode: A selected program is running, held or waiting for a pre-defined delay before starting. In this mode, the operator can view status and program information. Program Define Mode 1: Used to view/create/edit programs.
59215 2 2.1 FRONT PANEL CONTROLS, INDICATORS & DISPLAYS CONTROLS MODE key: Changes mode of instrument. PROG key: Cycles through Program Numbers. Scroll key: Displays the next parameter in the sequence (indicated by Message Display - see Subsection 2.3). RUN/HOLD key: Runs, holds or aborts current program. Down key: Decrements displayed parameter value/cycles through options. Up key: Increments displayed parameter value/cycles through options.
59215 2.2 INDICATORS Control Status Indicators AT ON when Self-Tune is active; flashes when Pre-Tune is active. ALM Flashes when any alarm is active. OP1 ON when primary control output is active. OP2 ON when secondary control output (if fitted) is active. MAN ON when Manual Control is selected.
59215 2.3 DISPLAYS 2.4 ALARM STATUS INDICATION When any alarm is active, the ALM indicator will flash.
59215 2.5 VIEWING PROGRAM AND CONTROLLER PARAMETERS In Base Mode (i.e.
59215 3 3.1 PROGRAMS SELECTING AND RUNNING A PROGRAM When no program is running, the Setpoint Programmer is in Base Mode and the RUN and HLD indicators are OFF. In this mode, select a program as follows: 1. Hold down the PROG key until the required program number is displayed. 2. Press the Run/Hold key once to start the program. The RUN indicator will then go ON; the Setpoint Programmer is now in Program Run Mode. 3.
59215 3.5 VIEWING PROGRAM PROGRESS/STATUS In Program Run Mode, a number of displays are made available to the operator (in the Message Display area) which indicate program progress/status.
59215 3.6 ABORTING A PROGRAM The operator may abort (i.e. terminate) the current program by holding down the Run/Hold key for more than five seconds. When the program is aborted, a return is made to the Base Mode and the Message Display will show: This message will be removed by the next keypress. 3.7 “END OF PROGRAM” INDICATION When the program has reached its End Marker, the Message Display shows: and a return is made to Base Mode. 3.
59215 4 ADJUSTING THE SETPOINT With the Setpoint Programmer in Base Mode (i.e. with the RUN, HLD, SET and PRG indicators OFF), the two main displays will show the process variable value (upper display) and the setpoint value (lower display - Read Only). To change the setpoint value: 1. Press the Scroll key; the Message Area will display one of: according to input range. 2. Use the Up and Down keys to change the setpoint value (in the lower display) as required. 3.
59215 5 USING THE SELF-TUNE FACILITY The Self-Tune facility is used to optimise tuning whilst the Controller part of the Setpoint Programmer is operating. Self Tune may be activated as follows: 1. With the Setpoint Programmer in Base Mode (with the RUN and HLD indicators OFF), press the Scroll key until the Message Display shows: and the lower Main Display shows: 2. Press the MODE and Up keys to change the lower Main Display to: indicating that the Self-Tune facility is now activated.
59215 6 USING THE PRE-TUNE FACILITY The Pre-Tune facility is used to set the Setpoint Programmer’s PID control parameters to values which are approximately correct in order to provide a base from which the Self-Tune facility may subsequently optimise tuning. Pre-Tune may be activated as follows: 1. With the Setpoint Programmer in Base Mode (with the RUN and HLD indicators OFF), press the Scroll key until the Message Display shows: and the lower Main Display shows: 2.
59215 7 MANUAL CONTROL In any mode except Configuration Mode or Calibration Mode, the operator may select manual control of the process by simultaneously pressing the Scroll and MODE keys. The Setpoint Programmer will then enter Base Mode or (if a program is currently running) Program Run Mode with the program held. The Message Display will show and the lower Main Display will show the power output value, which may then be adjusted using the Up and Down keys.
59215 8 DEFINING AND VIEWING A PROGRAM (PROGRAM DEFINE MODE) The Setpoint Programmer may be put into Program Define Mode from either Base Mode or Program Run Mode (i.e. with a program currently running). 8.1 ENTRY INTO PROGRAM DEFINE MODE 1. Press the Scroll and Up keys simultaneously. The lower Main Display will show 0 and the Message Display will show: 2. Use the Up and Down keys to set the value in the lower Main Display to the Program Define Mode Lock Value and press the Scroll key.

59215 8.3 PARAMETERS WHICH APPLY TO A SPECIFIC PROGRAM AS A WHOLE Parameter Cycle Count Message Display Function Available Settings (Lower Main Display) Defines the number of times a program will be executed 1 - 9999 Program will execute the set number of cycles Program will repeat indefinitely Auto Hold Selects operation of Auto Hold facility (relative to setpoint) - see Figure 8-1.
59215 Figure 8-1 59215-8 Auto Hold Operation Page 8-4
59215 8.4 PARAMETERS IN ANY/EACH SEGMENT IN A SPECIFIC PROGRAM Parameter Message Display Final Setpoint Value Function Available Settings (Lower Main Display) Defines the final setpoint value for this segment, selects a Dwell segment or indicates a Join, Repeat or End Marker Numeric value (limited by SPHi and SPLo) or (by pressing the Up and Down keys simultaneously) indicates a Dwell segment with: or, if the segment is already a Join, Repeat or End Marker, as shown below.
59215 CANCELLING JOIN, REPEAT OR END MARKERS To cancel a Join, Repeat or End Marker: (a) at the Final Setpoint Value parameter, press the Up and Down keys simultaneously to produce a Dwell segment, or (b) at the Segment Time/Ramp Rate parameter, increment the value to 0 or a positive value. 8.
59215 There are no restrictions on joining programs; several programs can be joined to one program (e.g. to provide user-selectable warm-up programs, depending upon which program is run first). The Cycle feature can be used to make more complex program sequences. Consider the two simple example programs previously described: and consider the case in which Program 1 is set to perform two cycles and is joined to Program 2.
59215 At the end of the tenth cycle of Program 2, the program sequence would end. 8.6 BASIC RULES TO REMEMBER In any program sequence: 8.7 * A program ending in a Join Marker will perform the required number of cycles of itself before joining the new program. * A program ending in a Repeat Marker (hence, by definition, the last program in the sequence) will perform the required number of cycles of itself before ending the sequence.
59215 9 DEFINING THE CONTROLLER PARAMETERS (CONTROLLER DEFINE MODE) Entry can be made into this mode from Program Define Mode, Program Run Mode or Base Mode. To enter from Base Mode or Program Run Mode: 1. Press the Scroll and Up keys simultaneously. The lower Main Display will show 0 and the Message Display will show: 2. Use the Up and Down keys to set the value in the lower Main Display to the Lock Code value (for Program Define Mode) and press the Scroll key.
59215 9.1 CONTROLLER PARAMETERS The Controller parameters appear in the following sequence: Parameter Message Display Function Available Settings/Values (Lower Main Display) Input Filter Time Constant Defines time constant for input filter (removes extraneous impulses from the process variable input 0.0secs. (filter OFF) to 100.0secs. on 0.5-sec. increments. Default = 2.0secs.
59215 Parameter Function Available Settings/Values (Lower Main Display) Setpoint Low Limit 6 The minimum limit for setpoint adjustment. Should be set to a value which prevents setpoint values causing damage to the process. Input Range Minimum to current setpoint value. Default = Input Range Min. Motor Travel Time 11 Time taken for valve to travel from one end stop to the other 5secs. to 5mins. Default = 1min.
59215 Parameter Message Display Function Available Settings/Values (Lower Main Display) Deviation (High/Low) Alarm 1 value If Alarm 1 is a Deviation (High/Low) Alarm, this defines a level above (positive value) or below (negative value) the setpoint. If the process variable deviates from the setpoint by a margin greater than this value, the alarm becomes active (see Figure 9-2) ±(input range) from setpoint. Default = 5 input units.
59215 Parameter Message Display Function Available Settings/Values (Lower Main Display) Loop Alarm Time If ON/OFF control is selected (i.e PB1 = 0) and Loop Alarm is enabled, this defines the duration of the saturation condition after which the Loop Alarm is activated (see Subsection 9.3) 1sec. to 99mins. 59secs. Default = 99mins. 59secs. Scale Range Decimal Point Position 9 For linear inputs, defines the decimal point position. 0 (xxxx) 1 (xxx.x) 2 (xx.xx) 3 (x.xxx) Default = 1 (xxx.
59215 NOTES ON CONTROLLER DEFINE MODE PARAMETERS (Cont.) 6. Internal software prevents (a) the Setpoint High Limit being given a value less than any setpoint value contained in currently-resident programs, and (b) the Setpoint Low Limit being given a value greater than any setpoint value contained in currently-resident programs. 7. Thes parameters are not applicable if the Recorder Output Option is not fitted. 8.
