Connection of Two Pairs of Closing Photocells, One
Monitored and One non Monitored
Opening/Closing Safety Devices:
They operate during the gate opening and closing move-
ments and are suitable to protect the opening and closing
areas against the risk of impact. Typically these photocells
work in combination with other monitored photocell pro-
tecting closing or opening entrapment zones. In that case
they can’t be monitored so they can only protect against
potential impact on vehicles.
