8.1. Connection of photocells and safety devices
Opening safety devices: they operate only during the gate opening movement and, therefore, are suitable for protecting the
zone between the gate as it opens and fixed obstacles (walls, etc) against the risk of impact and
crushing.
Closing safety devices: they operate only during the gate closing movement and, therefore, are suitable for protecting the
closing zone against the risk of impact.
N.B.: If one or more devices have the same function (opening or closing), they must be connected to each other in series. N.C.
contacts must be used.
