Figure 8 Versapro Timer State Diagram
The timer has four states. The IDLE state is the inactive condition. The RUN state is the active state when the
timer is counting down. The HOLD state is when counting is paused due to either Digital Event = HOLD or a
configured alarm is active. The END state is when the timer has timed-out but has not been acknowledged.
The configured alarm contact will activate when the END state is entered.
The following is a summary of ways to change the state of the Timer. These assume the standard setups are
in effect. It is assumed that the Timer is enabled for it to start or run.

1.
Timer Enable = YES and
2.

5.
