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).

•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.

3PROGRAMS
3.1SELECTING AND RUNNING A PROGRAM
With no program running, the Digital Controller Programmer is in Base Mode and
the RUN and HLDindicators 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 RUNindicator will
then go ON; the instrument is now in Program Run Mode.
3.2CHANGING 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 x60indicator will go ON. To cancel operation
on the x60 timebase, press the Down key for more than five seconds, whereupon
the x60indicator will go OFF.
3.3HOLDING A PROGRAM MANUALLY
You may hold or freeze a program by momentarily pressing the Run/Hold key. The
HLDindicator will then go ON (the RUNindicator staying ON) and the program
will stop execution. The program may subsequently be restarted by momentarily
pressing the Run/Hold key again.
HLDINDICATOR FLASHING:If, before the operator holds the program
manually, the HLDindicator 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 HLDindicator will go ON
continuously. When the operator removes the manual Hold (by pressing the
Run/Hold key again), the HLDindicator will either flash (indicating that the
Guaranteed Soak conditions still prevail) or go OFF (indicating that the
Guaranteed Soak conditions no longer exist).
RUNINDICATOR 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 RUNindicator will
come on continuously.
3-1

3.4JUMPING 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
programs may be joined or set to cycle, jumping past the last segment in a
program may result in changes in the Program Number and Cycle Count.
3.5VIEWING 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 UPkey 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 x60indicator is OFF) or minutes/seconds (if the x60
indicator is ON). The Delay Time display is alwaysin hours/minutes.
NOTE: If the SET UPkey 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 UPkey.
After all applicable program status/progress displays have been shown, press the
SET UPkey to return to the Base Mode displays.

3.6ABORTING 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.
3.8VIEWING PROGRAM AND CONTROLLER PARAMETERS
In Program Run Mode (i.e. with a program currently running or held), the MODE
key gives “view only” access to Program Define Mode and Controller Define
Mode:

VIEW ONLYVIEW ONLY
See Section 8See Section 9

4ADJUSTING THE SETPOINT
With the Digital Controller Programmer in Base Mode (i.e. with the RUN, HLD, SET
and PRGindicators 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 SET UPkey; the Message Area will display one of:
whichever is appropriate to the input range used.
2. Use the Up and Down keys to change the setpoint value (in the lower
display) as required.
3. When the setpoint value is set as desired, press the SET UPkey again to
return to the initial display.
4 -1

5USING 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 Digital Controller Programmer in Base Mode (with the RUN and
HLD indicators OFF), press the SET UPkey 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.
To de-activate the Self-Tune facility, press the SET UPkey to obtain the same
Message Display as above; then press the MODE and Up keys simultaneously to
change the lower Main Display from On to OFF.
5-1

6USING 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. With the Digital Controller Programmer in Base Mode (with the RUN and
HLD indicators OFF), press the SET UPkey 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 Pre-Tune facility is now activated.
NOTES
1. If the process variable is within 5% of the input span from the setpoint,
the Pre-Tune facility cannot be activated and any attempt to do so will
have no effect.
2. Since the Pre-Tune facility is a single-shot operation, it will automatically
de-activate itself once the operation is complete.
To de-activate the Pre-Tune facility manually (with the Digital Controller
Programmer in Base Mode), press the SET UP key to obtain the same Message
Display as above; then press the MODE and Up keys to change the lower Main
Display from Onto OFF.
6-1

7MANUAL CONTROL
In any mode except Configuration Mode or Calibration Mode, the operator may
select manual control of the process by simultaneously pressing the SET UPand
MODEkeys. The Digital Controller 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. Whilst manual control is being exercised,
the power output display is included in the displays available in Base Mode and
Program Run Mode.
To cancel manual control, press the SET UPand MODE keys simultaneously,
whereupon the power out value display and the PowerMessage Display will
disappear and the Digital Controller Programmer will remain in whatever mode
prevailed when manual control was cancelled (if this is Program Run Mode, the
currently-running program will be resumed from the point at which it was held).

8DEFINING 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).
8.1ENTRY INTO PROGRAM DEFINE MODE
1. Press the SET UPand 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 Value (defined by the user in Controller Define Mode) and press
the SET UPkey.
The Digital Controller Programmer will enter Program Define Mode, the SET and
PRGindicators will go ON and the operator will be able to edit programs and
segments. The MODE key can then be used (a) to switch to Controller Define
Mode (see Section 9), and then (b) to show a Message Display:
To return to Program Define Mode (and re-start the Program Define/Controller
Define/Exit?display cycle), press the MODE key; to return to Base Mode, press the
SET UPkey.
If an incorrect lock value is entered, a return is made to Base Mode.
Program parameters are divided into three categories:
(a) Those common to all programs - global parameters
(b) Those common to all segments in a specific program
(c) Those relevant to a specific segment in a specific program
Upon entry into Program Define Mode, the operator will be presented with the first
of a sequence of parameter displays (see following Subsections). The operator
may then step through the sequence, using the SET UPkey. The displayed
Program Number may be changed using the PROGkey and the displayed
Segment Number may be changed using the Run/Hold key.
NOTE: If entry is made from Program Run Mode and Program Lock is On,
only Controller Define Mode will be accessible.
