Trouble shooting

Electric motor does not operate
- Check that the battery main switch is 'ON' .
- Check whether the control panel fuse has burnt out.
- Check if the main fuse has burnt out.
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.
Control panel 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.
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 (- . -).
[1] The control current fuse is in the bow thruster motor. A spare fuse
can be found in the relay cap, see p. 111.
