MC_0418
• Always turn the control device off when the thruster is not in use or when leaving the boat.
• When leaving the boat always turn off the main power switch for the thruster.
• Never use thrusters out of water
• If the thruster stops giving thrust while running, stop running the thruster and turn it off. Running the thruster for more than a few seconds without
resistance from the propeller can cause serious damage to the thruster.
• If two control panels are operated in opposite directions at the same time, the thruster will not run.
If both are operated in the same direction, the thruster will run in this direction.
• If you notice any faults with the thruster switch it off to avoid further damage.
• The purpose of the thruster is to manoeuvre or dock the vessel. Forward or reverse speed must not exceed 4 knots when operated.
For the operation of thrusters
Never use thrusters when close to objects, persons or animals in the water. The thruster will draw objects into the tunnel and the rotating
propellers. This will cause serious injuries and damage the thruster.
Always turn the main power switch off before touching any part of the thruster. An incidental start while touching moving parts can cause
serious injuries.
It is the owner, captains or other responsible parties full responsibility to assess the risk of any unexpected incidents on the vessel.
If the thruster stops giving thrust for some reason while manoeuvring you must have considered a plan on how to avoid damage to persons or
other objects.
Failure to follow the considerations and precautions can cause serious injury, damage and will render all
warranties given by Sleipner Motor as VOID. MC_0411

Hydraulic System - PHC024 Setup MC_0095
PHC024 (Controller for hydraulic thrusters)
Confi guration of parameters is not supported with PHC024 fi rmware older than V1.101. This indicated by a
message stating:
FW too old. Parameters not supported!
Thruster can be operated with PHC024 fi rmware older than V1.101, but Danfoss service tool must be used
for confi guration.
Bow/Stern Direction (only available for PHC024 with FW V1.101 or higher):
Values: Normal (default)/Inverted
Switches between Normal and Inverted running direction for the thruster. Direction need to be inverted if
incorrect prop rotation.
Pump Control (only available for PHC024 with FW V1.101 or higher)
Values: Auto(default)/Always ON/Not Available
When «Pump Control» is set to «Auto», the system will automatically control load sharing between two PTO
pumps by deactivating the second PTO pump when not needed (two PTO pumps/control valves required) to
reduce heat generation in the system and save fuel/energy.
When any thruster is running, both PTO pumps will be active to ensure good performance. When an SPS
stabilizer system is active, one PTO pump will be deactivated to save power. If stabilizers are active and
the system pressure drops below 80bar, the system will activate the second PTO pump for 15 minutes
to increase the flow capacity and maintain required pressure. After 15 minutes the second pump will be
deactivated unless the pressure is still below 80 bar.
“Pump Control” is set to “Not Available” when “Thruster Stern” is set to “with Bypass Valve”. “Pump
Control” will then not be able to edit.
Cooling Pump (only available for PHC024 with FW V1.101 or higher)
Values: Always Running/Temp Controlled(default)
When the option “Temp Controlled” is selected, the cooling pump will start when oil temperature exceeds
50°C/122°F and stop when the oil temperature goes below 40°C/104°F. On systems with two oil tanks, this
setting will apply to both tanks.
Cooling Signal Output (only available for PHC024 with FW V1.101 or higher)
Values: Normal (default)/Inverted
Set to Normal when using a hydraulic cooling pump. Should be set to Inverted when using an electrical
cooling pump with a 10 2380A-12/24V relay box

Hydraulic System - PHC-3 Setup MC_0095
PHC-3 - Controller for hydraulic thrusters
PHC-3 has several parameters that can be changed for different setup requirements.
These parameters can also be confi gured directly on the PHC-3 controller’s display.
Firmware version and S-Link serial number are displayed at the bottom of the confi guration menu.
Bow/Stern Direction:
Values: Normal (default)/Inverted
Switches between Normal and Inverted running direction for the thruster. If the direction of thrust is
opposite of the direction of movement of the joystick this parameter can be used to align thrust direction
with the operation of the joystick.
Bow/Stern Function
Values: Normal (default), SRHP
Setup the control unit behavior.
- Normal: Tunnel thruster
- SRHP: Retractable thruster. PHC-3 with a retract controller. The retract controller must also
be set as SRHP.
Bow/Stern Asymmetric Thrust
Values: 0% to 100% (Default 100%)
This setting can be used to improve performance of dual bow or stern thruster installations such as those
found on catamarans or vessels with stern drive units. Pushing water at high flow into an adjacent tunnel
may result in cavitation and reduction of thrust for the nearby tunnel.
Pushing water towards the drive unit, above a certain flow rate, might not further increase the thrust. Thus
for vessels with stern drive and dual thruster installation the current consumption could potentially be
improved by reducing flow towards the drive unit while not reducing maximum achieved thrust.
The Asymmetric Thrust value limits maximum thrust in one direction. The limiting direction is determined
by the parameter 0101-INSTANCE of the PHC-3.
PHC-3 with 0101-INSTANCE set to NONE or PORT will limit thrust towards port side and hence reduce the
water flow towards starboard.
PHC-3 with 0101-INSTANCE set to STARBOARD will limit thrust towards starboard side and hence reduce
the water flow towards port.

Values: 50% to 100% (Default 100%)
Set the maximum output thrust of PDC-301 in percent. PDC-301 will scale the input signal to this value.
Load share limit
Values: 0% to 100% (Default 100%)
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.
See AC series thruster user manual (document ID 6054) for a detailed explanation and setup guide.

Values: ACS580 (default), VACON
Select the type of Variable Frequency Drive (VFD) to be controlled by PDC-301. Select ACS580 if the
drive is an ABB ACS580 or ACS880.
Asymmetric Thrust
Values: 0% to 100% (Default 100%)
This setting can be used to improve performance of dual bow or stern thruster installations such as
those found on catamarans or vessels with stern drive units. Pushing water at high flow into an adjacent
tunnel may result in cavitation and reduction of thrust for the nearby tunnel.
Pushing water towards the drive unit, above a certain flow rate, might not further increase the
thrust. Thus for vessels with stern drive and dual thruster installation the current consumption could
potentially be improved by reducing flow towards the drive unit while not reducing maximum achieved
thrust.
The Asymmetric Thrust value limits maximum thrust in one direction. The limiting direction is
determined by the Location setting of the thruster.
Thrusters with Location set to BOW or STERN will limit thrust towards port side and hence reduce the
water flow towards starboard.
Thrusters with Location set to BOW-STB/STERN-STB will limit thrust towards starboard side and hence
reduce the water flow towards port.
