Wiring Diagram for Category 4
Inputs shown with safety gate/guard in closed position. Two Series 300-B GuardSwitches™ with one INT relay are required for each safety gate.
When first applying the INT Safety Monitor Relay, the inputs must be cycled to check for proper operation before the output contacts close. To cycle the inputs, the guard must be
opened and then closed. This start-up test is sufficient; however, we recommend that the proper operation of the switches and relay be checked at least every 24 hours.

The two circuits do not switch simultaneously, and depend
on the speed of the guard closure. Based on closure speed
of 1' per second and a gap of 1/8", a delay less than
50 msec is typical.
