Sleipner S-Link Display Interface SDI-1 — Installation & User Manual

Technical Specification

The inch column of the dimension table in the manual is shifted against the mm values (as printed); work from the mm figures.

Compatibility & LEDs

• Displays status and operating information from all Sleipner S-Link compliant thrusters and stabilizer systems, except PHC-024.
• MFDs from Garmin, Raymarine and Navico/Simrad (check compatible models with the MFD manufacturer).
• Status LED: green constant = S-Link OK; green blinking = S-Link not connected; yellow blinking = firmware upgrade in progress; yellow constant = upgrade successful; red blinking = upgrade failed.
• ETH Link/Act LED: green blinking = Ethernet connected; off = not connected.
• At start-up the Status LED turns red and the ETH LED yellow, then red.

Thruster Dashboard

• Once SDI-1 is installed and powered, the Sleipner app appears on compatible MFDs (see your MFD manual to start third-party apps).
• Shows thruster type, applied thrust, direction and status for up to four thrusters, laid out by their physical location (bow / bow starboard / stern / stern starboard, e.g. catamarans).
• Two bow (or two stern) thrusters share one joystick and one thrust indicator.
• AC thrusters: motor temperature; DC thrusters: motor temperature and battery capacity (six levels); hydraulic: oil temperature (one symbol when one PHC-3 controls two thrusters). Temperature icon: green normal, yellow high, red alarm.
• Retractable thrusters deploy when a control panel is turned ON and retract when it is turned OFF; Deploy/Retract symbols show until fully done.
• AC thrusters with power management: a Waiting for VFD Power Available symbol shows until the VFD confirms power; an alarm triggers if no confirmation within 60 seconds.
• Two joysticks on the same thruster: same direction → the higher thrust is used and shown; opposing directions → no thrust until one joystick returns to zero.

Stabilizer Dashboard & Alarms

• Turn the stabilizer system ON/OFF and select At Anchor or Cruising; vessel roll and speed at the top, one icon per fin showing actual fin movement, lock icon when fins are locked.
• Switch between dashboards with the buttons at the bottom of the touch screen.
• Alarms broadcast on S-Link pop up on the MFD (the Sleipner app must be running). Thruster dashboard: blinking red background and an Access Alarm List icon lower left.
• A thruster with an active alarm cannot be operated, except for the PHC3 Oil over temperature and Low oil level alarms.
• Settings menu: stabilizer configuration, plus SDI-1 FW version, HW version and serial number under About.
• Fault codes can be looked up in Sleipner's Fault Code Navigator (QR code in the manual).

Cables & Connectors

Installation Rules

• Keep BACKBONE and SPUR lengths to a minimum; consult your distributor if the total BACKBONE exceeds 100 meters.
• Fasten cables to avoid sharp bends, chafe and strain on connectors; close the connector locks fully.
• Do not leave cables, T-Connectors or Extenders permanently immersed; make a U-bend before each product connector so water does not run into it.
• Ideally connect the POWER Cable in the middle of the BACKBONE for equal voltage drop at both ends.
• Route S-Link away from radio transmitters, antennas and high voltage cables.
• Unused SPUR cables may be left unterminated for future equipment: protect the open connectors from water.
• Connect only original Sleipner S-Link products or authorised equipment directly to the bus; third-party equipment goes through a Sleipner interface, and at least one original Sleipner control panel must still be installed.
