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.
m
WARNING: the sensor cables must not be run in the
same conduit as the motor cables.
• Connect power supply cables of photocells transmitter
between terminals
Z3
and
Z2
of the control unit.
• Connect power supply cables of photocells receiver between
terminals
Z1
and
Z2
of the control unit.
• Connect the N.C. exit of the photocell receivers of the 1 type
between terminal boxes
L7
and
L11
C
To activate the functions, change the
Fot1
parameter
settings
• Connect the N.C. exit of the photocell receivers of the 2 type
between terminal boxes
L8
and

WARNING:
• if several couples of same kind photocells are mounted, their
outputs must be connected in series.
• In case of reflection photocells, power supply must be
connected to terminals
Z3
and
Z2
of the control unit to carry
