Function description
} The safety relay must be activated by simultaneously pressing two control elements
(pushbuttons) within 0,5 s . If one or both pushbuttons are released or the contacts
open, the unit interrupts the control command for the hazardous movement.
} Reactivation: The output relays will not re-energise until both control elements have
been released and re-operated simultaneously or the contacts have opened and then
closed.
