PROBLEM
PROBABLE CAUSE
REMEDY
230 volt mains voltage absent
Check master switch
Emergency STOP present
Check for any STOP commands
connected to the STP input.
There is no jumper between the STP
input and the common.
If not used, check if there is a
jumper on the STP input.
One of the fuses is burnt out.
Replace the fuse with one of the
same value.
On giving a command with the
remote control or with the key-
switch, the gate
does not open
.
Motor power cable not connected or
faulty.
Check the connection of the cable
in the terminal board or replace it.
The photocell, if present, is
obstructed or not functioning.
Check, clean the photocell or
remove the obstacle.
The photocell is missing and there
is no jumper between the PHO input
and the common.
Check the accessory connections
and the presence of the “jumper”.
The gate opens but does not close.
A key selector NC contact has been
used instead of an NO contact to
connect to the STR input
Check the connections.
The operator functions by wire but
not with the remote control.
The remote control has not been
memorised or is broken or the
battery is flat.
Check/change the battery.
Carry out the remote control
acknowledgement procedure.
Check the lack of mains voltage.
The flashing light only functions for
4 seconds and the gate moves
slowly (only with a 12V optional
battery fitted).
No mains voltage: the control unit
functions with the battery.
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.
The gate moves then stops, both in
opening and closing.
The motor force is insufficient
and/or the trigger threshold of the
OBS is too low.
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.
There is an obstacle in front of the
gate; the hinges are blocked; a
motor fixing bracket has detached.
Check the motor fixings.
Check the electrical connection.
Check the correct positioning.
When commanded, the motor starts
but the gate does not move.
The electric lock, if present, does
not work (does not open).
Lubricate the mechanism.
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.
