PHOTO TEST
To ensure correct operation of the phototest function, the system must be equipped with two power lines for the photocells; the first connected to
terminals 1 and 2 (powering the receivers) and the second to terminals 3 and 4 powering the transmitters (the phototest must be enabled with dip-switch
no. 7 set to ON).
The control unit checks efficiency of the photocells by simulating activation at the start of each manoeuvre.
If all functions correctly, the motors are activated and the manoeuvre starts; if the receiver malfunctions, the cycle is stopped and a series of fast flashes
are emitted on the gate open indicator and led LD3.
The phototest function, as well as the obvious safety factor, offers the following advantages:
- energy saving (the transmitters of the photocells are off when the gate is closed)
- increased autonomy in the case of battery operation
- less wear of the photocell transmitter components.
- The phototest also works with photocell 3 (Jolly input).
- The control unit recognises and memorises (during time interval programming) which and how many photocells have been connected for
the phototest.
- On systems with the phototest function, when the gate is closed the photocell transmitters are not powered and the inputs are open (leds
off).
- To test the photocells when the gate is closed, short the two "Test" terminals (detail 11 of fig.1) on the control unit.
- The photocells with connections for the phototest function only work during the manoeuvre.
COUPLING TYPE RECEIVER model OC (optional)
The receivers are "self-learn" type and can memorise several codes on the same channel.
The functions of the two radio channels are:
Channel 1 Step/step
Channel 2 Pedestrian
To memorise the transmitters proceed as follows:
- Insert the receiver in the connector (detail 23 of fig. 1)
- Power up the control unit and wait for the receiver leds to turn off.
- On the receiver, briefly press the pushbutton of the channel to be memorised, (P1 step/step or P2 pedestrian) and the corresponding led starts to flash.
If the led emits double flashes, wait briefly and repeat the operation (the pushbutton must only be pressed once).
-Transmitter with remote control to be programmed.
- If the led on the receiver emits a longer flash, this means that memorisation is successful.
- If the code is already present in the memory, the receiver leds all flash simultaneously.
The code memory can be reset if required, by pressing and holding P1 on the receiver for approx. 15 seconds until all leds light up.
The aerial must be connected to terminals 42 (sheath) and 43 (control unit), see fig. 2.
- For further information and specifications, see the manual supplied with the receiver.
