MODE OF OPERATION
Upon application of power with the safety
switches closed, the load will energize. If any of
the safety switches open for longer than
600 ms, the fault light will come on and the load
will stay de-energized regardless of the state
of the safety switches. Power must then be
removed for 100 ms and safety switches must
be closed in order to reenergize the load, upon
which the fault light will be off.
INSTALLATION
