Trouble shooting

Electric motor does not operate
- Check that the battery main switch is 'ON' .
- Check whether the control panel fuse has burnt out. The control
current fuse is in the bow thruster motor. A spare fuse can be
found in the relay cap, see p. 78-83.
- Check if the main fuse has burnt out. See table on page
In all the above cases, the 'POWER' indicator LED is not lit.
- The electric motor has overheated and its thermal Protection has
broken the circuit of the control current.
The panel gives a warning signal three times ( . - . . - ) and the LED
will glow red.
As soon as the motor has cooled down enough, the LED will re-
sume glowing blue and the bow thruster can be put back in ser-
vice.
Check if it is possible to turn the propeller. A piece of wood or simi-
lar could have been caught between the propeller and the tunnel.
The shear pin of the actuator is broken
By mechanical overload, e.g. an obstacle has forced the hatch or
cruising a high speed while the thruster is deployed, the shear pin
can break.
• Make sure that the tunnel can move freely up and down and if
necessary, eliminate the cause of the breaking of the pin.
• Remove the broken shear pin
• Remove the fuse from the power supply of the CAN bus signal
• Run the actuator with an external power supply to the retracted
position until the motor is switched off by the end switch (change
plus and minus, the direction changes).
• Turn the rod of the actuator inwards by hand until it does not go
any further.
• Manually push the bow thruster motor to the retracted position
of the actuator until it does not move any further and the holes of
the actuator and holes on the bow thruster motor flange can be
aligned by unscrewing the actuator stem.
Do not unscrew the rod too far, otherwise there is too little
thread between the rod and the motor to transfer the forces.
• Install new shear pin (1) and refitted the safety clips (2). Connect
the cable running through the shear pin to the connector in the
cable harness and on the other side to the cable from the bow
thruster motor.
• Put the fuse back in the CAN-bus power cable.

Electric motor turns slowly
- The battery is flat.
- Bad electrical connection(s) due to e.g. corrosion.
- The carbon brushes are not making proper contact.
- The battery capacity is reduced because of very low temperatures.
- Weed or fishing line has become caught in the propeller.
Control circuit fuse is burnt out
- Short circuit in the operating circuit; check the wiring.
Electric motor turns (too) fast but there is no thrust
- The blades of the propeller have been damaged by a foreign ob-
ject having entered the propeller or tunnel.
- The drive pin on the propeller shaft has been broken by a foreign
object having entered the propeller or tunnel.
Replace the drive pin and check the propeller flange for any dam-
age.
This is not applicable for the 125 kgf and 160 kgf thrusters!
• Reset the installation by operating the panel, with the bow thrust-
er motor returning to its resting position. The panel switches off.
The installation is ready for use.
Reset procedure retrectable bow or stern thruster
If the retrectable remains in an undesired position, there are two
ways to reset the system.
• Press the on/off button until you hear an acoustic signal. After this,
the retractable will return to its resting position.
• Switch off the main power supply of the bow thruster motor and
remove the fuse from the CAN-bus power supply. Wait 10 seconds,
first reinsert the CAN-bus fuse and then switch the bow thruster
power supply back on.
The installation is ready for use.
