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.
