Option Range Description
OFF Release limit The threshold (in primary units) at which the
conditional expression would be evaluated to
false. Defines the hysteresis for analog
triggers. Not applicable for digital triggers.
On d Operate delay 0.1-999.9 sec The time delay before operation when the
operate conditions are fulfilled
OFFd Release delay 0.1-999.9 sec The time delay before release when the
release conditions are fulfilled
Act Action See Appendix C The action performed when the setpoint
expression is evaluated to true (the setpoint
is in operated state)

Using Numeric Triggers
For numeric (analog) triggers, you can specify two thresholds for each
trigger to provide hysteresis (dead band) for setpoint operations.
The Operate Limit defines the operating threshold, and the second Release
Limit defines the release threshold for the trigger. The trigger thresholds
are specified in primary units.
If you do not want to use hysteresis for the trigger, set the Release Limit
to the same value as the Operate Limit.
Using Binary Triggers
Binary (digital) triggers like digital inputs and relays are tested for
ON/CLOSED or OFF/OPEN status.
