vetus® Electronic engine remote control
16.2 Analysis of the electronic system behaviour
It follows a list of behaviours, error messages 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
8
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
enlightene
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 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 CAN address
Re-assign the CAN addresses
on the command station,
set correctly the dipswitches
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 CAN 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.
