Trouble shooting
Electric motor does not operate
- Check that the battery main switch is ‘ON’.
- The automatic control current breaker is switched off as a result of
overloading the control current circuit.
[1]
- Check if the main fuse has burnt out.
[2]
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 green 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 similar
could have been caught between the propeller and the tunnel.
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.
[1]
The control current breaker is located in the casing for the bow
thruster motor. Once the overload of the control current is cor-
rected, the control current breaker will switch itself back on.
Thus do NOT open the casing in order to reset the control current
breaker.

See table on page 97
Control current breaker switched off
[1]
- 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.
After pressing the on/off switch on the panel, the panel is
not switched on.
- The on/off switch must be pressed a
second
time within 6 sec-
onds.
The LED will then remain green and the buzzer will confirm that
the panel is ready for use by giving the signal (- . -).
