14. ELECTRICAL MEASUREMENTS
In normal “usage” mode, i.e. thrusters running, boat in the water, with fully charged
batteries under ongoing charge (alternator), electrical measurements should be made at
the following points:
At the batteries
At the battery cut-off switch
At the fuse
At the electric motor’s connections
At the power supply arriving at the thruster control box
These measurements will enable you to detect voltage drop.
NOTE: the voltage reading between the motor’s negative and positive connections
should be approximately 10.5V during operation.
The cumulative effect of voltage drops at these points can severely impair the
thruster's performance.
Should the voltage measured be too low, the following points need checking:
Are the batteries of sufficient capacity ?
Are the batteries good quality?
Are the batteries sufficiently charged?
Are appropriate cable sections being used?
Are the connections sufficiently tightened?
15. OPERATION
With the control system circuit breaker/ switch and manual battery isolator switched on:
Switch on the control panel, as previously described in the manual.
Push the red button or incline the joystick to the left and the boat moves to the left.
Push the green button or incline joystick to the right and the boat moves to the right.
If, during tests the boat moves in the wrong direction, change around the blue and the
brown wires on your power relay.
When manoeuvring remember that the boat’s momentum continues after you release the
joystick / button, therefore remember to release the control prior to reaching your desired
position.
Care must be taken not to use the thruster in areas where there may be people
swimming or floating debris.
Maximum running time: 2-3 min (depending on ambient temperature).
16. ALARMS OR THERMAL SWITCH-OFF
The thruster's electric motor is fitted with a thermal switch as standard. If the thruster
motor overheats the buzzer in the control panel will start beeping and the green LED in
the red-push button will flash until the thruster motor has cooled down again.
As soon as the overheating alarm sounds, there are 10 seconds of actual thruster use
before the unit automatically shuts down. The unit will then not be able to be switched on
again until the motor has cooled down.
