2 actuators
The 2 green LEDs show a
steady light when the levers are
in neutral
After
power up
Gearboxes are in neutral and
the installation works correctly
-
The 2 green LEDs are switched
off, even if the levers are in
neutral
Power supply is missing
Check if the display on the
actuator is enlightened:
if YES, verify the connection
of CANBus data
transmission cable;
if NO, check the electrical
installation (chapter 10).
The green LED is switched off,
even if the lever is in neutral
The push-pull cable of the
gearbox hasn’t come to the
assigned neutral position
(actuators with mechanical
interface)
Check and remove the
obstacle which doesn’t
permit the actuator to go to
neutral position (see
chapters 12 and 13)
Green LED is blinking with duty
cycle: 90% On and 10% Off
Command station is not
configured correctly with
respect to the type of
installation; command station
has been configured for

Are blinking the following LEDS:
•
Engine_left (green) +
Wrm/Sync (yellow)

Engine_right (green)
•
All the 4 LEDs together
There is a failure on mechanical
actuators, probably due to:
an extra load on push-pull
cables
wrong setting of the push-pull
cable strokes
Go to the actuator’s display
and check which is the cable
that has generated the
failure. On the display is
shown the message “E” or
“P” on the side where it has
occurred the failure (see
section 21.1.3), then:
•
replace the defective
push-pull cable
•
re-program the
strokes of the push-
pull cables (see
chapters 12 and 13).
