SEP120/215T Ignition Protected thruster assembly
version 1.2 - April 2014
• Ensure that you know the location of the main battery switch(es) that disconnects the thruster(s) from all power sources (batteries) so
that the thruster(s) can be turned off in case of a malfunction.
• Always turn the main power switch off before touching any part of the thruster, as an incidental start while touching moving parts can
cause serious injuries.
• Always turn the control device off when the thruster is not in use.
• The maximum continues usage time of the electrical thruster is approximately 3 minutes at full power. The electromotor has a built in
thermal cut-off switch that will shut off the electromotor if it is overheating and re-engage it when it has cooled down some. This should
be considered when planning your manoeuvring.
• Running the thruster at reduced effect results in less heating of the thrusters, significantly extending the operating time. Information
about thruster runtime is displayed on the PJC panel
• Never use a thruster close to somebody in the water, as the thruster will draw objects close by into the tunnel and contact with the
rotating propellers will cause serious injuries.
• With the boat on land, only run the thruster for a fraction of a second, as without resistance it will accelerate very fast to a damaging
rpm. Also, while the thruster is in air, make sure that the propellers have come to a complete stop before performing a directions change
of the thruster, as it might cause damage to the thruster.
• If the thruster stops giving thrust while the electromotor is running, chances are that there is a problem in the drive-system. You must
then immediately stop trying to run it, and turn it off, as running the electromotor for more than a few seconds without resistance from
the propeller, can cause serious damage to the electromotor.
• When leaving the boat always turn off the main power switch for the thruster.
• We advice to always keep the main engine(s) running while using a thruster. This will keep the batteries in a good charge condi-
tion. This will also give better performance to the thruster, as a higher voltage at the thruster results in a higher torque (power) in the
electromotor.
• Please note that the performance of a thruster strongly depends on the voltage available at the electromotor. This voltage will decrease
by time because aging batteries have a reduction of capacity. By installing new batteries the effect of the thruster should be back at
the original level.
• Make sure that only one control is used at the same time, if two panels are operated in opposite directions at the same time the thruster
will not run at all. If they are operated in the same direction the thruster will run with the largest power given by the two panels.
• If the thruster is not performing or functioning as usual, the cause for this must be found and corrected as soon as possible so to avoid
causing any other or further damage to the equipment. You must also turn off the main battery switch immediately in case the problem
is of electric origin.
• Never store anything (e.g. equipment, sails, ropes etc.) in the same compartment as the thruster. When the thruster runs for a longer
period it will get hot and will cause damage.
Warning
:
Tampering with the Ignition Protected stern thruster assembly or any attempt to disassemble anything on this thruster
assembly inside the boat can cause an explosion with very serious consequences.
If there is a problem with your Ignition Protected stern thruster, please contact your dealer.
Danger: NEVER Disassemble any part of the Ignition Protected stern thruster assembly
