Figure 30: Process interlock timing
The following setpoints are available. The setpoints and logic for interlock A shown below
applies to all interlocks A through J.
[Path: Home > Setpoints > Control > Interlock]
IL A Function
Range: Disabled, Trip, Stop, Alarm
Default: Disabled
This setpoint selects whether the process interlock causes a trip (reset required to restart
the motor), a stop (no reset required), or alarms only. The “Disabled” selection disables all
interlock functions, including the instantaneous alarm.
IL A Healthy State
Range: Open, Closed
Default: Closed
This setpoint allows the user to configure the process interlock contact input as either
healthy open or healthy closed. The switch state is healthy when no action is taken by
this interlock.
