FUNCTIONS
58 SG4 EXTENDED
Edge Trigger:
override engaged on contacts closing until at least one Muting sensor is
intercepted. In this case the override state rests even if the override contacts are
released. The device exits the override state when one of the following events happens:
• the Muting sensors are deactivated (T-Muting) or the Muting sensor are deacti-
vated AND no beams are intercepted (L-Muting)
• the timeout expires

ation: Override Mode

CAUTION
In such a case reactivation of normal operation could be not monitored by
an operator thus becoming virtually dangerous.
Please consider any possible risk and take necessary counter-measures if
edge override is selected.
