COURTESY LIGHT (18 Vdc - max. 15W)
The open gate indicator light comes on when an open command is given, and it stays on through-
out the manoeuvre and during the pause time; it goes off 2 minutes after the gate has closed.
BATTERY CHARGER BOARD (OPTIONAL)
If the system is equipped with a battery charger board, it con operate even during power failures.
If the voltage drops below 11.3 Vdc, the automation stops working (the control panel is still pow-
ered). When it drops below 10.2 Vdc, the board disconnects the battery completely (the control
panel is no longer powered).
OBSTACLE DETECTION
If the obstacle detection function (which can be set through trimmer FR) is activated during an
opening manoeuvre, the gate closes approx. 20 cm., if it is activated during a closing manoeuvre,
the gate opens all the way .
WARNING: the control panel logics may interpret mechanical friction as an
obstacle.
SLOW-DOWN
To prevent the gate from shuddering at the end of its travel, you can set (through the RALL
trimmer) the slow down function for the opening and closing manoeuvres at a distance of 10
to 100 cm from the end of travel (by rotating the trimmer clockwise the slow-down distance is
increased; vice-versa, by rotating it counter-clockwise the slow-down distance is diminished).
When setting the slow-down distance, you should take into account the weight of the gate as
well as mechanical frictions.
Note: the P-FC button on the board has the same function as the OPEN/CLOSE
button.
REALIGNMENT PROCEDURE
Should the Gate need to be operated manually, use the release system. After the manual operation:
• after a Mains Power Failure, such as a black-out (controller remains disconnected for a cer-
tain time), the gate will be moving slowly to allow the Controller to establish its Limits;
• after a Manual Operation without Mains Power Failure (controller remains connected) it will
take 4 to 5 complete cycles to complete the realignment procedure. During these cycles,
Limits and Soft-Stops will not be working.
MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
1- The automation does not start
a- Check there is 230Vac power supply with the multimeter;
b- Check that the NC contacts of the card are actually normally closed (2 green LEDs on);
c- Increase the FR trimmer to the limit;
d- Check that the fuses are intact with the multimeter.
2- The radio control has very little range
a- Check that the ground and the aerial signal connections have not been inverted;
b- Do not make joints to increase the length of the aerial wire;
c- Do not install the aerial in a low position or behind walls or pillars;
d- Check the state of the radio control batteries.
3- The gate opens the wrong way
Invert the motor connections on the terminal block (terminals 3 and 4 for M1; terminals 5
and 6 for M2).
