In normal operation mode, the controller displays the PV,
SP/Output.
In this mode you can process the following:
•
Start /Stop the Auto Tuning process,
•
Switch between Manual Mode and Auto Mode.
In Manual Mode, SP tracks PV. The operator directly controls
the controller output level.
In Auto Mode, you can adjust the Set Point.
•
Operate the Timer
•
View and acknowledge Failsafe and Alarms.
In the configuration mode, the configurator configures the function
parameters in authorized Set up Groups and enter "Mask" mode.
In automatic local mode, the controller operates from the local Set
Points and automatically adjusts the output to maintain the PV at
the desired value.
In this mode you can adjust the Set Point.
In Manual mode, the operator directly controls the controller output
level. The process variable and the percent output are displayed.
The configured High and Low Output Limits are disregarded and
the operator can change the output value, using the increment and
decrement keys, to the limits allowed by the output type (0 % to
100 % for a time proportioning output or –5 % to 105 % for a
current output).
