14. F.A.Q
Problem
The control unit LEDs
are turned off
The control unit does not enter
the programming sequence
The control unit completes the
programming sequence, but does
not respond to commands in the
standard operating mode
The control unit causes the
automation to start, but the latter
does not cover the full path
The transmitter does not function
The transmitter has little range
The control unit does not slow
down the gate
The control unit functions
correctly, but does not accept
wired start and pedestrian
commands
The control unit does not make
the dip-switch or trimmer
modifications effective
Symptoms / Causes
Mains power shortage
The fuses are damaged. Before
replacing them, disconnect the
mains electricity and verify that
there are no short-circuits in the
connections
When the button for accessing a
programming sequence is pressed,
all the LEDs flash. The control unit
protection has been activated
Problems with the safety devices,
once the programming sequence
is completed, the green stop and/
or photo LEDs are off
Photo-test of safety devices failed.
After a command is pressed for a
few seconds, the red "error" LED
turns on"
Obstacle detection problems. If
during the manoeuvre the control
unit detects power draw peaks, it
goes into obstacle present mode.
Intervention of the safety devices.
Check that the green "photo" and
"stop" LEDs remain lit throughout
the entire manoeuvre.
If there are multiple photocell
pairs,these may signal false
obstacles
When the programming sequence
mentioned in Paragraph 7.1 is
completed, the red "radio" LED
does not flash
The transmitter's range varies
in relation to the environmental
conditions
If the "Power" trimmer is too
high, the control unit in the space
set by default through the gate
path programming procedure is
unable to detect the change of
speed
When the start or ped contacts
are closed, the green "start" LED
emits brief flashes. The command
lock has been activated
Once the dip-switch or trimmer
positions have been modified,
the control unit does not make
the modifications effective. The
control unit protection has been
activated
Once the "power" trimmer, dip-
switch 1-2 "motor" or dip-switch
8 "func" positions have been
modified, no resulting effects
appear on the system
Solution
Check for the presence of input mains voltage - see Paragraph 6
Replace the fuses (see Paragraph 2.3). If the fuses get damaged
again, before replacing them disconnect all the cables and verify
the integrity of the PCB
Deactivate the protection - see Paragraph 13.1.
Check that the "PHO1", "PHO2" and "STOP" contacts are
closed
Deactivate the photo-test - see Paragraph 11.1.
First of all, verify that the system's works in the manual mode.
There must not be any points in which the gate leaf tends to
stop. Raise the "OBS" trimmer by turning it clockwise (see
Paragraph 3.2). If insufficient, increase the "POWER" trimmer
setting and reprogram the stroke. If the problem occurs at the
final stage of the path, it may be resolved by eliminating or
minimising the slowdown points (see Paragraph 8.3)
Try bridging the "PHO1", "PHO2" and "STOP" contacts to
verify whether the problem can be resolved. Otherwise, connect
the photocells with alternating receivers
Verify the transmitter's compatibility: the code must be V2.
If the transmitter's LED does not light up clearly, replace the
battery
Replace the transmitter's battery. Should this not be sufficient,
the control unit is configured for connecting external antennas.
Reduce the setting of the POWER trimmer and reprogram the
stroke; if this is not sufficient, program the deceleration points
(par. 5.3) and set a longer deceleration zone.
Deactivate the pedestrian and start block. See paragraph 12.2
Deactivate the control unit lock. See Paragraph 13.1
To make the "power" trimmer or dip-switch 1-2 "motor"
modifications effective, the basic or advanced path
programming must be redone. Should this not be possible, the
control unit lock has been activated. See Paragraph 13.1
