The EMD safety relay has a retriggerable input. Retriggerable operation only
works in off-delay applications. Retriggerable operation is accomplished by
connecting a jumper from terminal B1 to B2.
Table 4 describes the off-delay
operation.
Jog Input
When the EMD safety relay is configured for the Jog functions, terminal B1
must be connected to +24V DC.

If the safety input is triggered and cleared within the duration of the time delay,
then the timing request is ignored and the safety output contacts remain closed.
The B1 indicator is ON.
Non-retriggerable None
The full time delay lapses and the safety output contacts open before the relay can
be reset.
The B1 indicator is OFF.
