If you have severely overheating oil - do not operate any hydraulics - run main engines (if pumps
are connected) at less load while giving the oil time to cool down.
X
If you are running out of oil in your tank - beware that the pumps will be destroyed if run dry and
can then also cause other damage to the power source driving them. If you have to run engines
with pumps directly fitted, disconnect mechanically the pump first so that it does not pump. If you
have severely overheating oil - do not operate
X
If an alarm occurs so the stabilizer system is not running, but the fins are centred and locked, you can
operate the boat normally, remembering the general warning about high speeds and inactive stabiliz-
ers as well as ensuring safe engine running without damaging central hydraulic parts - last section in
table below. If the fins are NOT centered and locked, please see table below for operational limita-
tions of the boat.

ECU temp high
The stabilizer controller is getting too hot.
Ventilate the room were ECU is sitting
L1
Decouple valve x Current
Sense
The ECU is reading that there is either a fault
with the electric activation of the mentioned
valve or a cable or cable connection issue
Do not run the system except in case of
emergency if oil temp. rise above 75˚C!
L2
Lock Valve xx
Current Sense
The ECU is reading that there is either a fault
with the electric activation of the mentioned
valve or a cable or cable connection issue
Check control cables between the ECU and
the related fin control valve.
L2
Servo Valve xx
Current Sense
The ECU is reading that there is either a fault
with the electric activation of the mentioned
valve or a cable or cable connection issue
Check control cables between the ECU and
the related fin control valve.
L2
Dump Valve Current
Sense
The ECU is reading that there is either a fault
with the electric activation of the mentioned
valve or a cable or cable connection issue
Check control cables between the ECU and
the accumulator valve block. When shutting
down the boat you will need to manually
release pressure in the accumulator tank
L1
GPS Signal Missing
The ECU has lost the GPS input signal after a
valid signal was present.
Reset the alarm and see if the signal have
returned. Rare loss of GPS coverage might
occur. If the alarm is triggered more than
once, check the cables and connectors
between the ECU and the GPS antenna.
L2
PHC Communication
Error
The ECU have lost contact with the PHC hy-
draulic controller. The controller is fitted to the
hydraulic tank assembly. It communicates with
the ECU using S-link.
Check that the green LED on the PHC
controller is lit. Check S-link cables and con-
nections.
L2
SHD Communication
Error
The ECU have lost contact with the SHD
power pack controller. The controller is fitted
to the hydraulic tank assembly or in a separate
enclosure. It communicates with the ECU using
S-link.
Check that the green LED on the SHD
control board is lit. Check S-link cables and
connections.
L2
NMEA2000 Gear Status
Unavailable
Stabilizer system can not read NMEA 2000
data from engine controls.
Check GW-1 connections and wires. Inspect
LED indications on GW-1.
L1
Hydraulic Pressure High
Faulty or shorted Stabilizer pressure sensor.
Check wiring for shorts or replace sensor.
