5 flashes: absence of encoder signal;
Check wiring, check encoder through TEST-ENCODER (optional), verify that the motor turns freely if
powered directly by the battery, check fuse F2;
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.
8 flashes: no motor signal.
check wiring, check that the motor rotates freely when powered directly by battery, check fuse F2.
Multiple errors are signalled by a 2-second pause between signals. Errors will continue to be sig-
nalled until a complete opening and closing manoeuvre is executed.
If the safety devices are activated 5 consecutive times during the same opening or closing manoeu-
vre, the control unit will switch to slow-down mode as it searches for the closing travel limit. To reset,
the gate must execute a complete opening and closing cycle, otherwise the travel limit search phase
will start again each time the safety devices are activated.
OBSTACLE DETECTION
If the obstacle detection function (which can be set through trimmer FR) is activated during an open-
ing 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 150 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 O/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 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.

ADVANCED FUNCTIONS

Clock function: a timer can be connected to the open-close pushbutton in order to keep the gate
open at certain times during the day, after which it reverts to automatic closing.
Note: The gate remains open as long as the Op/Cl input continues to be activated.
"Open only" function: setting dip 1 to ON and dip 4 to OFF, the Op/Cl input will function solely as an
opening command and the gate will close only after the automatic closure time has elapsed.
"Gate contact open" function: setting dip 7 and dip 8 to OFF, the 2nd ch radio (terminals 16 - 17)
will act as a no-voltage contact which indicates when the gate is open. This function can be used to
connect "ZONE LIGHTING" or as a gate open signal.
