3.10 Viewing Setpoint And Control Status
In Base Mode (with no program running), repeatedly pressing the SCROLL key will
cause the control to display various control information. The operator may view and
change the setpoint. The operator may also view the units the control is using, whether
the outputs are on or off, the alarm status, the present time and day (if the real time
clock is fitted), and the percent output of the control instrument (if operating in Manual
Mode).
NOTE: If the SCROLL key is held for more than two seconds, the instrument will
automatically scroll through the displays.
3.11 Viewing And Adjusting The Controller Setpoint
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
other Base Mode parameters.
3.12 Viewing The Input Units
To see what type of input the control is using press the SCROLL key until the Units
display is shown. The Units display shows the temperature scale for thermocouple and
RTD inputs
types. This display can be deactivated, if desired.
