7.8.1 Override mode
It’s possible to configure the trigger of override inputs: Level or Edge.
As explained in diagrams below two types of override trigger sequence are accepted on
external inputs:
-
Level Trigger:
override engaged until both contacts are closed AND at least one muting
sensor is intercepted.
OVERRIDE STATUS is an output signal that informs the user if the override inputs are active
with override conditions present.
Fig. 49 – Override timings (level trigger)
-
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 deactivated AND no
beams are intercepted (L-muting)
- the timeout expires
OVERRIDE STATUS is an output signal that informs the user if the override inputs are active
with override conditions present.
