  • Page 6: Introducing The Dcp 100T

    INTRODUCING THE DCP 100T The DCP 100T Digital Controller Programmer is a powerful, easy-to-use -DIN setpoint programmer with full PID control capability (complete with Self-Tune and 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.
  • Page 7 • Support software (Off-Line Configurator, On-Line Graphic Program Editor) - operates via RS485 communications link. The Digital Controller 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.

  • Page 12: Programs

    PROGRAMS SELECTING AND RUNNING A PROGRAM With no program running, the Digital Controller 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 un til the re quired pro gram number is dis played.

  • Page 13: Jumping To The Next Segment

    JUMPING TO THE NEXT SEGMENT At any time during a program’s execution, the operator may jump forward to the next segment by simultaneously pressing the PROG and Up keys. Note that, since pro grams may be joined or set to cy cle, jump ing past the last seg ment in a pro gram may re sult in changes in the Pro gram Num ber and Cy cle Count.

  • Page 14: Aborting A Program

    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.

  • Page 15: Adjusting The Setpoint

    ADJUSTING THE SETPOINT With the Digital Controller 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.

  • Page 16: Using The Self-Tune Facility

    USING THE SELF-TUNE FACILITY The Self-Tune facility is used to optimise tuning whilst the Controller part of the Digital Controller Programmer is operating. Self Tune may be activated as follows: 1. With the Digi tal Con trol ler Pro gram mer in Base Mode (with the RUN and HLD in di ca tors OFF), press the SET UP key un til the Mes sage Dis play shows: and the lower Main Dis play shows:...

  • Page 17: Using The Pre-Tune Facility

    USING THE PRE-TUNE FACILITY The Pre-Tune facility is used to set the Digital Controller 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.

  • Page 18: Manual Control

    MANUAL CONTROL In any mode except Configuration Mode or Calibration Mode, the operator may select manual control of the process by simultaneously pressing the SET UP and MODE keys. The Digital Controller Programmer will then enter Base Mode or (if a program is currently running) Program Run Mode with the program held.

  • Page 19: Defining And Viewing A Program

    DEFINING AND VIEWING A PROGRAM (PROGRAM DEFINE MODE) The Digital Controller Programmer may be put into Program Define Mode from either Base Mode or Program Run Mode (i.e. with a program currently running). ENTRY INTO PROGRAM DEFINE MODE 1. Press the SET UP and Up keys si mul ta ne ously. The lower Main Dis play will show 0 and the Mes sage Dis play will show: 2.
