5. Electrical connection of the photocell
The photocell works with the gate automation control units. It is recommended that the
electrical installation and connection of photocells made a person with appropriate
quali
fi
cations.
- Installation of one pair of photocells (without synchronization function)
Place the
jumpers in the transmitter and receiver in the
position. Connect the
SYNCH
OFF
power supply 12-24V AC / DC to the transmitter and the receiver of the photocell. The PWR
diodes in the transmitter and receiver and the RX diode in the receiver should be on. If AC
power is used, power the transmitter and receiver using the same phase (from one power
supply). Connect the signal output of the photocell receiver (usually NC and C) to the
corresponding input on the control unit. Pay special attention to the control method (NC or
NO) required in the control panel.The standard solution in gate automation is the operation of
optical sensors in the NC con
fi
guration.
