6 Maintenance
For maintenance, please consult the 'Maintenance and Warranty
Book' supplied. Art. code 020901.01.
7 Protection
The bow thruster is equipped with, among other things, protection
against:
- Overheating of the motor or of the controller.
If the temperature of the motor or the regulator exceeds a cer-
tain value, the output power of the bow thruster motor will be
reduced.
- Overload of the motor,
- The batteries being deeply discharged.
If a problem occurs, the control panel will sound a warning sound
once (1) didahdididah (. -.. -) and the LED will flash red.
If the problem is no longer present, the control panel sounds a signal
didi (..) and the red LED turns off.
BOWPRO A
In the event of problems with the bow thruster, the LEDs on the indi-
cator panel indicate the following:
Temperature of the motor or
the controller too high.
Current too high or short
circuit.
Battery voltage is too high or
too low.
Motor blocked.
General error.

voltage.
8 Trouble shooting
Electric motor does not operate
- Check that the battery main switch is 'ON' .
- Check that the battery voltage is correct:
- 12 V bow thruster : 10.5 - 14.4 V,
- 24 V bow thruster : 21.0 - 28.8 V,
- 48 V bow thruster : 42.0 - 57.6 V.
- Check if the control current fuse has blown. [1]
- Check whether the fuse of the CAN bus power supply has blown.
- Check whether one of the main supply fuses has blown. [2]
In all the above cases, the "POWER" LED on the motor does not light
up.
- An overload has occurred, see protections.
As soon as the controller has cooled down sufficiently the LED will
turn green again and the bow thruster can be used again.
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 motor or regulator has become too hot, the motor is running
at reduced power.
- Weed or fishing line has become caught in the propeller.
Control panel fuse is blown
- Short circuit in the operating circuit; check the wiring.
Electric motor rotates, 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 is broken due to an object
in the tunnel.
Replace the drive pin and check the hub of the propeller for dam-
age.
*) Except the BOWB150 (150 kgf ), which does not have a drive
pin.
After pressing the on/off switch on the panel, the panel
does not switch 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 showing the signal (- . -).
- When the on/off switch is pressed, the joystick is not in the middle
position.
[1] The control circuit fuse is located on the controller.
