DCP 100T Digital Controller Programmer Installation ManualEN1I-6241

In normal operation, the operator must not remove the
controller from its housing or have unrestricted access to
the rear terminals, as this would provide potential contact
with hazardous live parts.

Installation and configuration must be undertaken by
technically competent servicing personnel. This is covered
in the Installation Manual (see above).

1 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.

• Facility to join programs to one another in any sequence (maximum

program length 121 segments).

• User can change currently-running program segment.

• Delayed Start of Program facility.

• End of Program relay output.

• Universal input - thermocouple, RTD (Pt100) or DC linear

- user- selectable).

• Universal power supply (90 - 264V ac 50/60Hz).

• Configurable from front panel.

• Comprehensive front panel displays.

• Front panel sealing to NEMA 4 standard.

• Behind-panel depth only 100mm.

Optional features include:

• Remote control and selection of program (plug-in option).

• Up to four Event relay outputs (plug-in option).

• Second control output.

• Recorder output (setpoint or process variable).

• RS485 serial communications.

• User-definable program tag names

• Real Time Clock

1-1

• 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. In this mode, the operator can view
status and program information.

Program Define Mode 1: Used to view/create/edit programs. This mode is
entered either from Base Mode (selected program may be edited/created)
or from Program Run Mode (currently-running program may be edited).

Controller Define Mode 2: Used to define the Controller characteristics.

2.2 INDICATORS

2.2.1 Control Status Indicators

AT ON - Self-Tune active; flashing - Pre-Tune active
ALM Flashes when any alarm active
OUT1 ON when primary control outputis active
OUT2 ON when secondary control output (if fitted) is active.
MAN ON when Manual Control is selected.

2.2.2 Run Status Indicators

RUN ON - Program running or (if HLD ON also) program held

Flashing - Program in Delayed state.

HLD ON - Program Held

Flashing - Program in Guaranteed Soak

x60 OFF - Timebase = hours/minutes

ON - Timebase = minutes/seconds

2.2.3 Event Indicators

Each indicates the status (active or inactive) of a user-defined
event (OFF = inactive, ON = active).

2.2.4 Mode Indicators

SET ON when Controller Define Mode or Program Define Mode

is entered; flashes when viewing parameters in Controller
Define Mode or Program Define Mode after entry from
Base Mode

PRG ON when Program Define Mode is entered.

2.4 ALARM STATUS INDICATION

When any alarm is active, the ALM indicator will flash. To view the alarm status in
the Message Display, press the SET UP key until a display appears of the form:

2.5 VIEWING PROGRAM AND CONTROLLER PARAMETERS

In Base Mode (i.e. with no program currently running or held), the MODE key gives

“view only” access to Program Define Mode and Controller Define Mode:

3 PROGRAMS

3.1 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.

2. Press the Run/Hold key once to start the pro gram. The RUN in di ca tor will

then go ON; the instrument is now in Pro gram Run Mode.

3.2 CHANGING THE PROGRAM TIMEBASE

Whilst a program is running, the normal timebase is hours/minutes. To change to a
timebase of minutes/seconds (i.e. select the x60 facility), press the Up key for more

than five seconds, whereupon the x60 indicator will go ON. To cancel operation

on the x60 timebase, press the Down key for more than five seconds, whereupon

the x60 indicator will go OFF.

3.3 HOLDING A PROGRAM MANUALLY

You may hold or freeze a program by momentarily pressing the Run/Hold key. The

HLD indicator will then go ON (the RUN indicator staying ON) and the program

will stop execution. The program may subsequently be restarted by momentarily
pressing the Run/Hold key again.

HLD INDICATOR FLASHING: If, before the operator holds the program
manually, the HLD indicator starts flashing, this indicates that the program

is currently subject to a Guaranteed Soak (see Subsection 8.3). If the

Run/Hold key is pressed (for a manual Hold), the HLD indicator will go ON

continuously. When the operator removes the manual Hold (by pressing the

Run/Hold key again), the HLD indicator will either flash (indicating that the

Guaranteed Soak conditions still prevail) or go OFF (indicating that the
Guaranteed Soak conditions no longer exist).

RUN INDICATOR FLASHING: This indicates that the program is in a Delay

state i.e. is timed to start after a user-defined delay has elapsed. When the

delay period has elapsed, the program will run and the RUN indicator will

come on continuously.

3.4 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.

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. Whilst the

current program is running, held or delayed, press the SET UP key to cycle

through a sequence of program status displays with the following legends in the
Message Display:

In the case of Segment Time Remaining or Guaranteed Soak Time display, the

time is in hours/minutes (if the x60 indicator is OFF) or minutes/seconds (if the x60

indicator is ON). The Delay Time display is always in hours/minutes.

NOTE: If the SET UP key is held for two seconds or longer, the Digital

Controller Programmer will auto-scroll through the above display cycle (with
the exception of the Self-Tune and Pre-Tune displays). To stop the

Auto-scroll, press any key other than the SET UP key.

Af ter all ap pli ca ble pro gram status/prog ress dis plays have been shown, press the

SET UP key to re turn to the Base Mode dis plays.
