15 - F.A.Q
Problems
9a The control unit LEDs are turned
off
9b The control unit cannot enter to
programming mode
9c
The control unit completes the
programming setup, but does
not respond to commands in
the standard operating mode
9d Door is moving but not all the
way to fully close and/or open
9e
The radio transmitter does not
functioning
9f
The transmitter has little range
9g
The door does not slowing down
9h
The control unit does not
make the dip-switch or knobs
adjustments
Symptoms / Causes
No power to the control unit
The fuses blown. You must
disconnect power before touching
fuses. Check for no short-circuits
or problems before replacing fuse
with same value ones
When the SET button is pressed
and all the indication LEDs flash
the control unit is in protection
mode
Problem with safety and/or stop
circuits if Photo and/or Stop red
LEDs are off. Those LEDs must
be lit red unless the door will not
work
Photo-test of safety devices failed.
After a command is pressed for a
few seconds, the red "Error" LED
turns on
Obstacle detection problems. The
control unit detects power draw
peaks during the manoeuvre and
goes into obstacle mode
Intervention of the safety devices.
Check that the red "S2 Photo",
red "S1 Edge" and "Stop" LEDs
remain lit throughout the entire
manoeuvre. If there are multiple
photocell pairs, these may signal
false obstacles.
Check that LED on the transmitter
is flashing, if not replace the
transmitter's battery
Note: transmitter's range varies
in relation to the environmental
conditions
Repeating the automation's
movement programming is
required
The control unit protection (lock
mode) is active
No effect with "POWER" knob or
dipswitches adjustment

Solution
Check for mains power
Replace the fuses. If the fuses blow up again, check for
short circuits or damages of power circuits, cables, wires,
accessories, transformer and control unit
Deactivate the protection – see Paragraph 14.1
Check that the "S2 Photo", "S1 Edge" and "Stop"
circuits are closed
Deactivate the photo-test – see Paragraph 4.1
1. Disengage the door from the motor(s) with manual
release; check door to move free all the way. If not,
please fix. 2. Turn the "OBS" knob slightly clockwise
(see Paragraph 4.2)
2. make sure that control unit stops powering the mo-
tor(s) at the end of the travel.
3. If not sufficient, turn the "POWER" knob slightly
clock- wise and reprogram automation's movement.
4. Avoid/reduce slowdown travel phase (see Paragraph
6.2)
Apply the bridges to "S2 Photo", "S1 Edge" and "Stop"
to check if the problem is from the control unit or other
circuits connected to these terminals
Check that radio LED of the control unit flashes while
pressing a button on the transmitter. If yes, try to
reprogram the radio transmitter
Replace the transmitter's battery. Connect an external
antenna (see Paragraph 10.8) if not sufficient
1. Repeat the automation's movement programming
(see Paragraph 6.1)
2. If not sufficient, do the advanced programming of
the automation's movement (Paragraph 6.2) and set
a longer slowdown area
Deactivate the control unit lock. See Paragraph 14.1
To make "POWER" knob and dip-switches changes
effective, it is necessary to repeat the automation's
movement programming. If not possible, deactivate the
cotrol unit lock. See Paragraph 14.1.
