7 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
resume glowing green and the bow thruster can be put back in
service.
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 tempera­
tures.
­ 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.
[1] The control current fuse is in the bow thruster motor.
