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
In order to avoid that the bar slams at the end of its movement, the slowdown of the bar during
opening and closing can be set (by means of the RALL trimmer) at a distance between 10 and
100 cm (rotating the trimmer clockwise the slowdown distance is increased; vice versa, turning
the trimmer anti-clockwise the slowdown distance is shortened). Set the RALL trimmer to its
maximum for CITY/V, RBL4 and RBLO.
Note: the P1 button on the control unit has the same function as the OPEN/CLOSE but-
ton.

MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
The automation does not start
a- Check there is 230V AC 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)
