Single Setpoint/Base Mode Control
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 until the Message Area displays Setpoint.
2. If Setpoint has been enabled in the Enable Mode, the UP and DOWN keys may
be used to change the setpoint value (in the lower display) as required.
3. When the setpoint value is set as desired, press the SCROLL key again to view
the input units.
4. Press the SCROLL key until Outputs is displayed in the message display. Use
the up and down arrow keys to turn output on or off.

1. Hold down the PROF 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, or flash if a delayed start has been programmed. The instrument is
now in Program Run Mode. In Program Run Mode, the process setpoint and
event outputs are controlled by the program selected.
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

pressing the RUN/HOLD key again.

HLD indicator may start flashing. This indicates that the program is currently subject to
a Deviation-Hold. If the RUN/HOLD key is pressed (for a manual Hold), the HLD
