3.4 Special electric connections: photocells

The protection system by means of photocells is composed of one or
more PAIRS of devices, one of them is the TRANSMITTER and the
other is the RECEIVER. Fig.16-17
The first transmits an invisible infrared ray picked up by the receiver; in
case the ray were interrupted the equipment will open a relay which
shall transmit a signal to the programmer 7853 that shall provide to
invert the motors operation direction during the wings closing.
Caution: Carry out connections according to diagram Fig.16. In
case photocells were more than ONE pair, carry out connection in
SERIES. Provide for a digging in the ground sufficient to lay a cable
duct crossing the gate width.
1. Cable having a minimum cross section of 0.5 mm 2 SHALL BE
PROTECTED BY A PROPER SHEATH.
2. In case of double safety device, provide for a DOUBLE PASSAGE.
3. Position the receiver in front of the transmitter at the same height
(40/60 cm).
4. The red led off indicates a perfect alignment.
5. Install the photocells cables far from cable ducts to avoid
interference.
6. Never assemble the receiver in front of the sun.
7. In case of double safety device, alternate a receiver with a
transmitter Fig. 16
3.5 Emergency battery
The system can also operate AUTOMATICALLY, i.e. without power
supply coming from the mains supply. By installing a 12V 6,3 Amp.
battery, it will be possible to carry out approx. 30 emergency
operations without power supply.
The battery can be fit in the proper space inside the plastic casing
containing the control unit. The programmer 7853 is provided with an
automatic device able to keep the battery charged. Provide for the
connection of the battery to the Fig. 14 terminals complying with the
polarity. Before using the system with only the battery it shall be first
charged for at least 24 h.
3.6 Key selector assembly
The key selector allows to start the operation by turning the control key
clockwise. Avoid to use simultaneously the radio transmitter. The
selector can operate the gate according to the set program.
The contact is Normally Open N.O. In case more than one selector or
possibly a switch were to be fitted, carry out parallel connections.
It is equipped with a FORCE-PROOF device as it cannot be opened
without the key.
Caution: for a higher force-proof safety, we advise to make the
connection cable pass inside a walled cable duct.

3.7 Blinker

This device is foreseen by all safety EEC norms, and it has to be
installed in a visible position.
Size and light features are in compliance with norms in force.
The device operates at LOW VOLTAGE and is provided with a lamp
holder and a 12V 10W bulb.
Caution: Never exceed this power as there might be the risk of
damaging circuits.
- Operation: the intermittent signal comes from the control unit.
Fig. 12
- The activation starts 2 seconds before each operation.
- The blinking is slow when the gate opens and faster when the gate
closes.
