5.5 - PHOTOCELLS

The control unit considers two kinds of photocells, depending on
the terminal to which they are connected:
Photocell 1
Photocells installed on the gate inner side, which are active both
during the opening and the closing phase.
When photocells 1 operate, the control unit stops the gate; as
soon as the photocell beam is free, the control unit will open the
gate completely.
m
WARNING: Type 1 photocells must be installed so that
they completely cover the opening area of the gate.
Photocell 2
Photocells installed on the external gate side and which are active
during the closing phase only.
When photocells 2 operate, the control unit opens the gate
immediately, without waiting for release.
The control unit supplies a 24Vac power supply to photocells and
it can perform a photocell operation test before starting the gate
opening phase.
NOTE: Photocell power terminals are protected by an electronic
fuse that stops current in case of overload.
