In normal operation, the operator must not remove the Setpoint
Programmer 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 only by personnel
who are technically-competent and authorised to do so . This is
covered in the Site Manual (see above).

59215
The Setpoint Programmer is a powerful, easy-to-use
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.
*
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.
*
1
-DIN instrument with full PID control
4
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
*
Support software (Off-Line Configurator, On-Line Graphic Program
*
Editor) - operates via RS485 communications link.

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. 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.
1 Entry via Lock Code; also optional Program Lock prevents changing of program definitions while a
program is running.
2 Entry via a Lock Code.

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 Scroll 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
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 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 Set point Pro gram mer 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
The operator 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 progam 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 an Auto-Hold (see
Subsection 8.3 and Figure 8 -1 ). 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
Auto-Hold conditions still prevail) or go OFF (indicating that the
Auto-Hold 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 Scroll 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 Auto-Hold 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 Scroll key is held for two seconds or longer, the
Setpoint 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 Scroll key.
Af ter all ap pli ca ble pro gram status/prog ress dis plays have been shown, press the Scroll
key to re turn to the Base Mode dis plays.
