21.2. Analysis of the electronic system behavior
It follows a list of behaviours and errors and their possible remedies.
Symptom
What to check
What to do
Where to look
on the product
manual
After power up, there is
no light on command
station or on actuators
Power supply is missing,
check the causes:
Circuit breaker not correctly
connected
Check and eventually
replace the circuit breaker
Electrical cables from the
battery to the actuator
Check and fix supply cables
The fuse on the actuator is
blown-up
Verify that the power supply
connector of the actuator is
wired with the correct
polarity.
Chapters 5 and
10
The 4 LEDS blink twice
at power on but then the
green LEDS are off and
the command station
doesn’t take the
command
Check that end of line
resistance terminations have
been correctly activated both
on actuators and on
command stations.
Program dip-switches
according to your installation
scheme.
Section 4.4. and
chapters 7 and
8
LEDs on command
station are never
enlightened while the
display on the actuator is
enlightened
CANBus data transmission
cable doesn’t transmit power
from actuator to command
station
Check if the CANBus data
transmission cable is
correctly connected on the
command station (connector
nut requires 5.5 turns of the
nut to be fully seated). If
power supply is still missing,
replace the CANBus data
transmission cable.
Chapter 6
Without moving any lever
of the command station,
the actuator generates
changes of speed or
unpredictable
engagement of the gear
2 command stations have the
same CANBus address.
You must re-assign the
CANbus addresses on the
command station, set
correctly the dip-switches
positioned below the
command station.
Section 4.4. and
chapters 7 and
8
Only one lever
commands both the
actuators, while the
second lever is not active
Command station is in
Synchro mode
De-activate the Synchro
mode with the push-buttons
on the command station.
Chapter 3
The two actuators might have
the same CANBus address
and receive the command
from the same lever.
Program dip-switch JP14
according to the following:
JP14 = OFF for the left
actuator
JP14 = ON for the right
actuator
Verify also that JP19 is
programmed according to the
installation scheme that you
have chosen (see from
section 7.1 to section 7.5).
Section 4.4. and
chapters 7 and
8
LEDs have faint light or
the reaction time to the
command is very slow
Check battery voltage
The motor doesn’t reach
the correct minimum or
maximum speed
(installations with
mechanical actuators)
Check if the stroke of the
push pull cable is correct,
both on the engine and on the
actuator
Tune the push-pull cable on
the engine and make a
precise setting of the stroke
on the actuator.
