sequences of flashes:
steady: ok;
1 flash: photo test error after three unsuccessful attempts;
Disable photo test (dip-switch 6 OFF), check photocells and relative connections;
2 flashes: photocells have been engaged;
Disengage the photocells, verify their operation and relative connections;
More than one error is indicated by means of a 2 second pause between one signal and the next.
GATE OPEN INDICATOR (24 Vac – max. 3W)
During the opening and closing cycles, the gate open indicator flashes in time with the LED (flashing).
It then remains steady when the gate is totally open. After the closing phase has been completed, it
turns off.
The gate open indicator also signals:
• the presence of obstacles near the gate after 5 unsuccessful attempts to complete the closing
cycle; flashes in time with the flashing light.
TIMED OPENING AND CLOSING
The gate can be opened and closed by means of a digital clock with a relay output contact.
Simply connect it to terminals 17 - 18 (OPEN/CLOSE button) and programme it so that, at the required
opening time, the relay contact of the clock closes until the required closing time (when the relay
contact of the clock opens once again, thereby allowing automatic closing).
Note: automatic closing must be enabled (Dip-switch 1 ON).
SELECTING MOTOR INPUT VOLTAGE
Select the operating voltage of the motors (140 - 160 - 180 - 200 Vac) using terminal 24 on the control
board and the output for the required voltage on the transformer.
Note: DISCONNECT the transformer before selecting a voltage.
6. 433.92 MHz BUILT-IN RADIO RECEIVER
The radio receiver can learn up to a maximum of 8 dip-switches (TXD2, TXD4, BUG2, BUG4, K-SLIM,
K-SLIM-C, T-4, T-4C) or rolling codes (BUG2R, BUG4R, K-SLIM-RP, T-4RP) which can be set on the two
channels as required.
The first channel directly commands the control board for opening the automatic device; the second
channel commands a relay for a N.O. no-voltage output contact (terminals 9 and 10, max. 24 Vac, 1 A).
The learning mode (dip-switch or rolling code) is determined by the first radio control device and
remains unchanged until all the codes have been cancelled.
LEARNING SYSTEM FOR RADIO CONTROL DEVICES
P1 = 2nd channel
1_ press button P2 briefly to associate a radio control device with the OPEN/CLOSE function;
2_ LED DL1 turns off to indicate that the code learning mode has been activated (if no code is entered within
10 seconds, the board exits the programming mode);
3_ press the button of the relative radio control device;
4_ LED DL1 turns on again to indicate that the code has been memorised (if this does not happen, wait 10
seconds and start again from point 1);
5_ to memorise codes to other radio control devices, repeat the procedure from point 1 up to a maximum
of 8 transmitters;
6_ to memorise codes on the 2nd channel, repeat the procedure from point 1 using button P1 instead of P2;
7_ to exit the learning mode without memorising a code, press button P1 or P2 briefly.
Note: if the maximum number of radio control devices (8) is exceeded, LED DL1 flashes rapidly for
about 3 seconds without memorising the code.
CANCELLING CODES FROM RADIO CONTROL DEVICES
1_ keep button P2 pressed for 3 seconds in order to cancel all the associated radio control devices;
2_ LED DL1 flashes slowly to indicate that the cancellation mode has been activated;
3_ press button P2 again for 3 seconds;
4_ LED DL1 turns off for approx. 3 seconds and then remains steady to indicate that the code has been
cancelled;
5_ repeat the procedure from point 1 using button P1 to cancel all the associated radio control devices;
6_ to exit the learning mode without memorising a code, press button P1 or P2 briefly.
ATTENTION: TO memorise a code on a new type of remote control unit (e.g.: from dip-switch to
P2 = OPEN/CLOSE
