Basic Troubleshooting
*
Not applicable to SX thrusters.
Before seeking assistance from the website help desk from your Sleipner dealer/ distributor, please perform these tests.
(NB: If you are unable to understand or perform these checks, you must consult a Sleipner distributor.)
CHECK SOLUTION
The motor runs, but there is no thrust
Check propellers are fi tted, fastened correctly and there
is no damage to the prop shaft.
Re-fasten or replace if necessary
*
Check the flexible coupling between the motor and
drive shaft is fi tted correctly and not damaged.
Replace if necessary
*
Check the gear leg is not damaged.
Replace if necessary
The thrusters performance is reduced
Check the propeller, gear house and tunnel are free from
growth/ barnacles or debris and damage.
Remove growth and clean. (NB: If there is obstruction in the tunnel it will disturb/ block
the water flow and signifi cantly reduce performance.)
Check the battery is in a good working condition.
(NB: Keep the main engine(s) running in use to have a continuous charge to the
batteries)
• Check batteries are not worn out or in a bad charged condition
• Check electrical connections/ wiring for damage or wear (corrosion)
• Check cables are the correct size per the product manual
• Tighten/ re-adjust connections
The thruster does not start/ works in only one direction or does not turn off
Check the main switch is active/ on. Open the main switch if it is closed.
Check all battery fuses are in good condition.
• Check batteries
• Check electrical connections/ wiring for damage or wear (corrosion)
• Tighten/ re-adjust and clean connections
The thruster is not shutting off after the Joy Stick/ panel
is disengaged.
Hit the main switch to disengage the thruster. Contact and consult a Sleipner distributor
as the control system has been damaged.
The thruster works in only one direction
Damaged relay.
Hit the main switch to disengage the thruster. Contact and consult a Sleipner distributor
as the control system has been damaged.
The thruster runs in a pulsing action
This is a build-in error response.
-Solenoids failure
Hit the main switch to disengage the thruster. Contact and consult a Sleipner distributor.
The solenoid might be in a lock-in/ auto stop position. Hit the main switch to disengage the thruster. Contact and consult a Sleipner distributor.
Replace if
necessary

PDC-301 Load Sharing
MC_0347
PDC-301 Load Sharing
The Load Sharing limitation allows the system to limit the combined load on the generator from a bow and stern thruster when both thrusters are used
at the same time. The load sharing will dynamically limit the thrust request for each thruster depending on the joystick position and limit settings.
Load Sharing is confi gured by adjusting the PDC-301 parameter “Load share limit” in SETUP from any PJC2xx panel.
Example of Load Share operation:
The Bow PDC-301 “Load share limit” is set to 60%, and the Stern PDC-301 “Load share limit” is set to 80%,
In the example, if the Bow thruster is operated at 100% thrust, output is reduced proportionally down to the limit value of 60% when the Stern joystick
exceeds 60% signal. If the stern thruster is operated at 100% thrust, output is reduced proportionally down to the limit value of 80% when the Bow
joystick exceeds 80% signal. In the example, the bow thruster will run at 60% and stern at 80% if both joysticks are at full in any direction.
How to fi nd SAC thruster power load in kW
In PJC2xx panel, enter
SETUP->INFO->THRUSTER INFO
select
Bow PDC-301
.
You will see this info screen for the Bow PDC-301:
Motor: speed (rpm), temperature (°C/°F), Power (kW), AC current (A) & AC voltage (V).
Thrust: Joystick thrust (%)
Ensure it is safe to run thruster at full speed before the next step.
Run the Bow SAC thruster with 100% thrust (to starboard or port) and read the maximum power consumption (in kW) of the Bow SAC thruster in the
display. Do the same for Stern SAC thruster.
If the installation has two Bow and/ or Stern SAC thrusters, read power from each PDC-301 and add them together.
How to limit SAC thrusters to a fi xed maximum power load
Bow SAC thruster maximum power consumption is 40kW and Bow Load share limit is set to 60%.
Stern SAC thruster maximum power consumption is 30kW and Stern Load share limit is set to 80%.
The maximum load is then calculated when running Bow and Stern at 100% joystick signal.
Bow thruster load = 40kW * 60% = 24kW
Stern thruster load = 30kW * 80% = 24kW
Total thruster load = Bow 24kW + Stern 24kW = 48kW
The limit levels for bow and stern thruster can be set to best balance diff erent thruster sizes or to prioritize one of the thrusters in the limit state.
