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.
17. SAFETY
Switch off means to cut the power at both the DC equipment panel (control power supply)
& the thruster battery isolator (thruster power supply) after having used the thruster.
Under no circumstances should any flammable products be stored next to the electric
components of the thruster. Care must be taken not to use the thruster in areas where
there may be people swimming or in the water close to the thruster.
CAUTION: Never tamper with the thruster / thruster turbine if not 100% sure that both the
control and power circuits have been isolated, except if taking electrical measurements
on the thruster motor or relay.
18. MAINTENANCE
Control panels should be protected from the natural elements while the thruster is not in
use.
The thruster requires a minimum of ongoing maintenance:
Check the condition and charge of the batteries regularly, as voltage drop is the most
frequent cause of rapid deterioration of the relay.
Carry out a regular check of all electric components: batteries, connections, power
cables.
Remove the motor and clean out dust from the motor-brushes with compressed air.
The electric motor must be kept dry and well-ventilated.
NOTE: All maintenance should be carried out by qualified and authorised personnel.
Composite drive leg and propellers:
The composite drive leg is pre-filled with oil and sealed for life. It does not require the oil
changing.
The composite drive leg does not require an anode.
The composite drive leg must not be disassembled, even partially (this would void the
warranty).
When the boat is out of the water, check that there are no fishing lines, plastic bags, etc.
caught in the propellers.s
Paint the drive leg and propellers with antifouling (make sure that they were well
prepared and primer has been used).
Always keep the propellers and tunnel clean.
To prevent the build up of calcium on the drive shafts, which would damage the oil seals,
cover the drive shaft and the oil seals’ stainless steel covers with silicon grease before
fitting the propeller(s). This should be done on an annual basis after the cleaning of the
outside of the leg. Do not use aggressive solvents as they may damage drive leg seals.
If drive leg oil seals are found to be worn, replace the drive leg with a standard exchange
unit.
