MALFUNCTION
DL1 flashes green/red alter-
nately.
During LEARNING motor
won't move.
With Mechanical Switch con-
nected, door can't complete
LEARNING process.
Door opens but not closes.
Doors stops and revert op-
eration. The following cycle
is performed at reduced
speed.
Door opens a little bit, then
closes at reduced speed.
DL1 3 yellow flashes
Door won't open in "BLOC-
CATA
CHIUSA"
(LOCKED)
program with EMERGENCY
input.
Battery is connected, but
door won't open in case of
power failure.
motor movement timeout
encoder faulty or disconnected
motor faulty
motor absorption exceeding the limits
motor direction reversed
POSSIBLE CAUSE
LEARNING Missing.
Safety or Command Inputs are not
correctly connected.
Safety or Command Inputs are in
use.
Mechanical Switch is set on "SOLO
ENTRATA" (ENTRY ONLY).
Sensor or Photocell detect an obsta-
cle.
Dip # 3 on SW1 is set on OFF and bat-
tery is not connected, faulty or low.
The door found an obstacle.
The following cycle is performed at
reduced speed.
Encoder is damaged or not properly
connected.
Encoder not working

ACTION
Perform LEARNING as de-
scribed in LEARNING section.
Check connections on wire ter-
minals.
Remove obstacle from Sensor
or Photocells detection range.
Set Mechanical Switch either
on "ENTRAMBI I SENSI" (AUTO)
or "BLOCCATA CHIUSA"
(LOCKED).
Remove obstacle from Sensor
or Photocells detection range;
check efficiency of detection
devices.
Check connection and efficien-
cy of the battery operated anti-
panic device.
Remove the obstacle.
The door has excessive friction
which is seen as an obstacle
Check the door movement, if
necessary adjust trimmers TR3
and TR4 (force).
Check the encoder 4-pole con-
nector is inserted.
Check the encoder cable or re-
place the encoder as required.
Select a different program, or
set the DIP # 1 on SW1 to ON
to enable EMERGENCY input.
Set DIP # 3 on SW1 on ON to
enable automatic opening in
case of power failure.
