Battery/charger check
Check the battery for clean and tight terminals and correct electrolyte level.
Check the charging voltage measured on the battery.
Correct charging voltage at 20°C (68°F) is:
14.4 V on 12 V systems
28.8 V on 24 V systems
7.4.
High current cable/connections check
Check all high current components and connections, including battery fuse, main switch, possible
bulkhead feed-through, motor and control unit connections.
Minimum voltage measured on the motor during operation should be min.;
10.5 V on 12 V systems
21.0 V on 24 V systems
All thruster performance specifications measured by 10.5 / 21 V.
If the voltage is below 10.5 V / 21 V the contactor will have low contact pressure. The contacts can then
easily burn or fuse together and the thruster contactor must then be replaced.
NB:
The electronic security system will, if necessary, cut the power and the thruster will stop.
7.5.
Joystick/operator panel check
The motor can be tested in both directions without the joystick/operator panel connected, as described
below.
Short between terminal 1 and 2 on the control unit and the motor will run in one direction.
Short between 2 and 3 and the motor will run in the opposite direction.
Measure zero resistance, with wires disconnected from the control unit, between the green and
brown wire, and between the brown and white wire from the joystick/operator panel when operating
the lever/switch.
This test will show whether the joystick/operator panel (with cable) is working and whether the
control unit is working.
8. Troubleshooting
8.1.
The thruster does not work
Turn on the thruster main switch.
Check fuse.
Check battery voltage.
Check all electrical connections on the control unit and battery cables.
8.2.
The thruster does not work or has an
unexpectedly low performance
Check the voltage at the control unit terminal (battery
+
and
battery- ) while trying to run it. If measured voltage of less
than 10.5 V (12 V system) and 21 V (24 V system) the
performance will drop and in the end the thruster will stop
working.
If wireless remote is correctly coded and available, check the
“POWER” indicator on the remote.
Green light
Green light indicates that voltage and sytem is ok.
Orange light
Low voltage at the electronic unit is indicated by an orange
light in the “POWER” indicator.
