Unsuitable limit switch
setting
Check and adjust the position of the end stop sliding plates
and that they activate the control spring.
CHAPTER 9: TROUBLESHOOTING GUIDE
PROBLEM
CAUSE
SOLUTION
The gearmotor
is not working
Fuse fault
Replace the fuse.
No power
The gate does
not move or
the motor slips
Obstacle impact control
cutting in
Motor force setting
not optimal
Repeat the work times and impact force setting
programming.
The gate does
not complete
its travel
Unsuitable gearmotor
position
Check that the distance between the end stop sliding plate and
the front, outgoing trim of the spring is between 25 and 35 mm.
Unsuitable limit switch
sliding plate
setting
The gate is
jammed against
the mechanical
end stop
Remove the lower casing from the motor.
Unscrew the nuts fastening the base plate bolts.
Remove the motor from its position by releasing the pinion
from the tooth rack.
By hand, move the gate right away from the mechanical
end stop.
Release the motor manually.
Reposition the motor on the base plate.
Set the end stop sliding plates properly.
Replace the lower casing and secure the motor.
If necessary, repeat the work times and impact force setting
programming.
Check the motor power supply input terminals to see if they are
live.
Check that the power supply cable is not cut or broken (cable
replacement must be carried out by an authorised technician).
Check F4 mains fuse efficiency
Check the 24V presence at the motor power supply clamps 5 and 6
Release the gate manually and check that there are no
obstacles. If obstacles are found, remove them.
Repeat the “work times and impact force setting
programming” procedure, setting a greater force.
N.B. The impact control can be switched off by
positioning the SW1 microswitch 1 to ON;
in this
case, other safety systems compliant with regulations
in force (e.g. sensitive edges) must be adopted. This
is extremely important as
THE INSTALLER IS
LIABLE FOR THE SYSTEM AND FOR ENSURING
ITS OPERATION COMPLIES WITH LEGAL
PROVISIONS.
The remote
control range
is reduced
Unsuitable antenna
connection
Check that the antenna is connected correctly to
terminals 24 and 25.
External antenna
required
To permit maximum reception distance, replace the
internal antenna on the flashing light with an external
one (SERAI OG/50 -SR 25.50).
SOG/4A receiver
in use
Replace the built-in receiver with the SOG/4A card.
The first opening manoeuvre takes place during deceleration (if
the gate is in an intermediate position) and can take up to 300 s;
if it does not occur within this time, the gate must be moved to
the fully open or fully closed position by hand (see chapter 8).
