9. TROUBLESHOOTING

PROBLEM
On giving a command with the
remote control or with the key-
switch, the gate does not open.
The gate opens but does not close.
The operator functions by wire but
not with the remote control.
The flashing light only functions for
4 seconds and the gate moves
slowly (only with a 12V optional
battery fitted).
The gate moves then stops, both in
opening and closing.
When commanded, the motor starts
but the gate does not move.
N.B.: If the problem persists, contact your Retailer or the nearest Service Centre.
ATTENTION: Before sending a remote control to be repaired, check that the batteries are not flat. 50% of
all remote controls that return for servicing only have flat batteries.
ENGLISH
PROBABLE CAUSE
230 volt mains voltage absent
Emergency STOP present
There is no jumper between the STP
input and the common.
One of the fuses is burnt out.
Motor power cable not connected or
faulty.
The photocell, if present, is
obstructed or not functioning.
The photocell is missing and there
is no jumper between the PHO input
and the common.
A key selector NC contact has been
used instead of an NO contact to
connect to the STR input
The remote control has not been
memorised or is broken or the
battery is flat.
No mains voltage: the control unit
functions with the battery.
The motor force is insufficient
and/or the trigger threshold of the
OBS is too low.
There is an obstacle in front of the
gate; the hinges are blocked; a
motor fixing bracket has detached.
The electric lock, if present, does
not work (does not open).

REMEDY
Check master switch
Check for any STOP commands
connected to the STP input.
If not used, check if there is a
jumper on the STP input.
Replace the fuse with one of the
same value.
Check the connection of the cable
in the terminal board or replace it.
Check, clean the photocell or
remove the obstacle.
Check the accessory connections
and the presence of the "jumper".
Check the connections.
Check/change the battery.
Carry out the remote control
acknowledgement procedure.
Check the lack of mains voltage.
Functioning is normal because it is
only powered by the battery.
Check if the leaves are in axis,
lubricate if necessary.
Increase the trigger threshold by
turning the OBS trimmer clockwise.
If it is not sufficient, increase the
FOR trimmer clockwise and
reprogram from RESET
Remove any obstacles from the
gate; restore the hinges, replace or
lubricate them.
Check the motor fixings.
Check the electrical connection.
Check the correct positioning.
Lubricate the mechanism.
