Sleipner Electric Stabilizers — User Manual

System Overview & Safety

• Covers DC models (24/48V) SPS40E, SPS50E, SPS60E and AC models SPS60E, SPS70E, SPS80E, SPS100E, SPS110E, SPS120E.
• Two (or four) movable fins on shaft and actuator assemblies through each side of the hull, driven DC or AC depending on actuator size, gyro-controlled over the Sleipner S-Link (CANbus) network. They reduce roll underway and at anchor.
• Keep the system engaged whenever the boat runs planing or semi-planing, even in calm water: the fins are part of the directional and roll stability at speed, and fins left fixed can make the boat heel and handle unpredictably.
• If the system fails: reduce speed to where the boat's natural stability copes. If the fins do not lock in reverse (sensor or other fault), reverse only at minimal speed.
• Never run the stabilizers with anyone or anything in or near the water; check clearance from docks, mooring lines and submerged objects – fins may extend beyond the hull sides.

Operation

1. From the Home screen select STABILIZERS.
2. Cruising Mode: press the Stabilizer ON/OFF button. The button turns blue (a green ring in the other user manual edition), the fin lock symbols disappear. Typically used from 3–4 knots; below that the fins centre and lock, and operation resumes as speed increases.
3. At Anchor Mode: press the Anchor button (0–4 knots). With both modes active the system switches automatically with speed; with At Anchor off it turns off below 3 knots.
4. To stop: press ON/OFF – the fins centre and lock. The system can also be switched from a PJC-2xx panel.

• Backing: in reverse the fins centre and lock automatically and BACKING shows (a warning state); afterwards the system resumes or turns off according to the Suspend Exit State setting.
• Disabled fins show on the front screen (SCU fault or switched off manually). Disable a fin to reduce forward forces, when at anchor without room, alongside a quay or another boat, or with swimmers near the fin.

Stabilizer Modes & Gain

Alarms, Warnings & Updates

• Alarms (red) are serious, immediate issues; warnings (yellow) are developing issues or normal states such as Backing, Reduced Power Mode, High Temperature Derate or Low Voltage Derate. They can coexist: always read the list.
• Fix the cause before pressing Clear All Alarms; clearing without fixing does not remove the warning. Each alarm has a description and a QR code; Sleipner's Fault Code Navigator gives fault descriptions and guidance.
• Fault history: Home → S-Link Devices → device → Fault History. Logging and Remote Control (PIN shown on the panel, network enabled) only when requested by Sleipner.

• S-Link device updates: by USB (S-Link Programmer → Tools → Download Manager → S-Link Offline Upgrade, to a good FAT32 USB stick in the port on the back of the panel) or over Wi-Fi/Ethernet from S-Link Devices → Upgrade. Updating from the TP-43A panel needs panel software V1.105 or newer.
• A communication failure during an upgrade forces the device into boot mode: repair the S-Link fault and retry. Turn Wi-Fi off after downloading, before resuming operation.

Maintenance Intervals

Service level: 1 = onboard, at sea; 2 = shore supported; 3 = trained personnel. D = vessel out of the water, W = vessel can be in the water. Whichever comes first, hours or time; skipping the schedule voids the warranty on the affected items.

• New installations or after major component replacement: inspect after the first 100 hours or first week – "shake" the fins from outside to check for play.
• Main shaft bearing life cannot be predicted: check bearing clearances periodically and inspect and clean the fins at every haul-out.
