Photocell & Safety Device Guide
Before connecting the photocells (or other devices) we advise you to select the type of operation according to the movement zone to be protected.
Opening Safety Devices: They operate only during the door opening movement and, therefore, they are suitable for protecting the zone between the opening leaves and fixed obstacles (walls, etc.) against the risk of impact and crushing.
Closing Safety Devices: They operate only during the door closing movement and, therefore, are suitable for protecting the closing zone against the risk of impact.
Opening/Closing Safety Devices: the operate during the door opening and closing movements and, therefore, they are suitable for protecting the opening and closing zones against the risk of impact.
If one or more devices have the same function (opening or closing) they must be connected to each other in series. Normally Closed contacts on the accessories panel must be used.
