Advanced Control Panel Troubleshooting
Control panels operating on the S-link system display all faults via the control panel interface or via other warming methods.
To review any issues of your product refer to the appropriate user manual for a complete list of fault codes and troubleshooting guides.

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.
