SE 50/140S ignition protected thruster assembly

Troubleshooting
Before seeking assistance at the help desk of your Side-Power dealer / distributor please perform these tests and make no-
tes of all measurements to ensure that they have as much information as possible to work on.
NB! All check points and solutions must be carried out after consulting the relevant information elsewhere in this manual to
under-stand how the system is intended to work. If you are unable to understand what to check, you must consult a profes
-
sional.
Solution
Remove motor and replace the drive pin
Re-fasten or replace the propeller and/or key.
In case of a failure inside the gearhouse, we advice to get a replacement gear-hou-
se instead of attempting to repear the internal gear and bearing system.
If wrong, contact your dealer or distributor to obtain parts with the correct voltage.
The no load voltage should be:
12V system =12,7V. If below 12,3V,your batteries are not in a good charge state
or worn out and must be recharged or replaced before trying to run the thruster.
If less than 8,5V at the thruster the voltage is to low for the thruster to operate
correctly. In a 24V boat the thruster will operate down to approx. 12V, but the
performance will be very bad. Find and correct the reason for this low voltage
which will probably be one or more of these points: main battery cable sizes and
connections, battery size and condition, fuse and main power switch performance.
If the thruster runs in both directions, try the same in the connector that goes into
the back of the control panel. If it also works in this position, check the contact and
wires on the back of the panel and try to engage this again by pushing both ON
buttons simultaneously. If the panel does not turn on (see control light), measure
the voltage between the Red and the Black in the contact going into the thruster. If
the voltage is good, chances are that the panel is not working.
If it works by the thruster, and not by the panel there is a bad contact or a broken
lead in the controlcables between these two test points.
Measure that you have the correct voltage between the Red (+) and all the other
colours in the contact. If you do not get a reading.
If less than 10,5 V, the thruster will not perform at specified effect.
If one or more brushes are loose/has no tension from the brush-spring, the perfor-
mance will be low.
If there are growth in the tunnel, this will disturb / block the waterflow and especi
-
ally barnacles on the propeller will greatly reduce performance.
Re-charge battery(ies), if this is not sufficient, replace battery(ies).
Check for bad cable connections, if necessary tighten/re-adjust connections.
Check cable size in accordance to manual.
Shut off thruster main switch, tap slightly on the motor to see if it will release. Turn
on thruster main switch. If solenoid is still in lock-in mode, contact your dealer.
Check
I
f the drive pin on the motor shaft is broken
Are the propellers in the tunnel fastened correctly on
the prop-shaft (key present)
With the motor removed, turn the driveshaft from
inside the boat to feel if the gears are engaging and
turning the prop-shaft.
Check that the voltage of the electromotor are correct
for your installation by their labels.
Check the voltage at the thruster between main minus
input and main plus input point:
Check the voltage at the thruster while you are trying
to run it. Keep main engine(s) running to have conti
-
nous charge to the batteries.
If the main solenoids on the thruster are not even try-
ing to engage (clicking) they are probably not getting
a "run" signal from the control system. Try to run the
thruster without the panel by directly connecting the
red and the blue or the red and the grey wires in the
controlcable contact coming from the thruster.
Check voltage at thruster when running
Check that all the brush-springs sits correctly on the
brushes in the electromotor.
Check that the propeller, gearhouse and tunnel is free
from growth / barnacles etc.
Solenoid flapping, most probable cause: low voltage.
Solenoid lock-in, auto stop of thruster, auto retry every
10 seconds.
»
The electromotor runs, but there is no thrust.
»
The thruster does not start at all or works only in one direction.
»
The thruster has an unexpected low performance.
»
The thruster runs for approximately 0,5 seconds every 4 seconds.
»
The thruster runs for approximately 0,5 seconds every 10 seconds.
