Note
To disable a low threshold process limit, set the P x value to negative full scale.
To disable a high threshold process limit, set the P x value to full scale.
Setting the Process Limit Source
The [PLS xy ]
 command sets the process limit source, where:
x: 1 = Relay A
2 = Relay B
y: 1 = Pressure
2 = Position
3 = Close Limit Switch
4 = Open Limit Switch
To report a process limit source, issue the request:
RLS
The controller responds with the message [PLS1x2y], where:
x: 1 = Relay A source pressure
2 = Relay A source position
3 = Relay A close limit switch
4 = Relay A open limit switch
y: 1 = Relay B source pressure
2 = Relay B source position
3 = Relay B close limit switch
4 = Relay B open limit switch
To report the process limit source enter:
RLS
An example response, if Relay A is driven by the open limit switch and Relay B is driven by the closed limit
switch is:
PLS1423
(code version 01.04.08 or newer)
Note
When the Process Limit Source is set to the open/closed limit switches the relay is driven
directly from the selected limit switch. The Process Limit is not used.
