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 P1 button on the board has the same function as the OPEN/CLOSE button.
TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening and closing of the gate can be controlled through a digital timer equipped with a
relay contact on the output. The timer must be connected to terminals 12 - 14 (OPEN/CLOSE
button) and can be programmed so that, at the desired opening time, the relay contact closes
until the desired closing time (when the timer's relay contact opens, enabling the automatic
closing of the gate).
Note: the automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
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 certain
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
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 (3 green LEDs on);
c- Set dip 6 (phototest) to OFF;
d- Increase the FR trimmer to the limit;
e- Check that the fuses are intact with the multimeter.
The radio control has very little range
a- Connect the radio aerial to the terminals of the receiver card and not to terminals 16-17
of the control card (for frequency 433,92 MHz);
b- Check that the ground and the aerial signal connections have not been inverted;
c- Do not make joints to increase the length of the aerial wire;
d- Do not install the aerial in a low position or behind walls or pillars;
e- Check the state of the radio control batteries.
The gate opens the wrong way
Invert the motor connections on the terminal block (terminals 23 and 24);
