6 flashes:
presence of obstacle after 5 failed attempts to close;
Make sure there are no obstacles across the path of the gate and that it slides smoothly;
7 flashes:
no memorization procedure has been executed;
Execute memorization procedure.
Multiple errors are signalled by a 2-second pause between signals.
If the encoder is activated 5 consecutive times during the same closing manoeuvre (obstacle
detection), the control unit opens completely. On the next manoeuvre, the control unit will switch
to slow-down mode as it searches for the closing travel limit.
GATE OPEN WARNING LIGHT (18V DC - max. 3W)
The gate open warning light flashes during the opening or closing manoeuvre in synchrony with
the flashing light, then shows a steady light when the gate has opened completely. Once the
closing manoeuvre has been completed this light goes off .
In addition, the gate open warning light signals the following:
• programming phase (when dip-switch 8 is set to ON);
it flashes in sync with the flashing light;
• mains power supply restored
it emits a series of flashes for approx. 2 seconds;
• presence of obstacles across the path of the gate after 5 attempts to close have failed;
it flashes in sync with the flashing light.
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 11,3V DC, the automation stops working (the control panel is still
powered). When it drops below 10,2V DC, 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 manoeu-
vre, 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.
The A/C 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 opera-
tion:
• 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.
