Page 13: Connection To Seldén Power Supply And Sel-Bus System
3.2 Connection to Seldén Power Supply and SEL-Bus system Install the three control cables from the mast motor to the motor control unit (MCU) “Furling mast”. Carefully note the position of cable colour and connector: L3= Grey L2= Orange L1= Brown The cables need to be connected to the MCU in the correct position/sequence. Incorrect positioning of the cables can damage the mast motor and break mechanism. For correct positioning of the Motor Control Unit, installation of the complete Power supply and SEL-Bus system, see separate manual 597-275-E. 3.7 Configuration of control buttons for Synchronized Main Furling For synchronized main furling, configuration of the control buttons for both the winch and furling mast must be done in the following order. For complete information about how to configure Motor control unit, MCU, to the control buttons, read installation manual 597-275-E. Press the configuration A. Configure winch MCU to winch buttons button on Winch MCU. Push and hold winch button 1 or 2 until the winch generates the start-up signal. - Page 14 Press the configuration B. Configure winch MCU to the MAIN button on Winch MCU. OUT button (for synchronized outhaul) Push and hold MAIN OUT until the winch generates the start-up signal. C. Configure furling mast MCU to the Press the configuration button on Furling mast MCU. MAIN OUT/IN buttons Push and hold IN until the mast motor generates the start-up signal. If the signal tone is generated when the Power supply and SEL-Bus system is turned on (without any button being pressed) turn the power off immediately. Inspect the push button connections; cables from SEL-Bus converter to push button must be installed as “normally open” not “normally closed”.

Page 15: Preparations Before Sailing
Preparations before sailing 4.1 Tensioning the luf f extrusion It is important that the luff extrusion inside the mast is correctly tensioned. An untensioned or over-tensioned luff extrusion can lead to increased furling load or unnecessary wear of the system. Control and adjustment of luff tension can be made on both a stepped and unstepped mast. The luff extrusion should be prevented from rotating. Use a torque wrench in the furling gear winch handle socket to measure the tensioning torque. Alternatively, measure the torque with a spring balance or similar combined with an ordinary winch handle. Tension to the correct value as required. It is important that the mast is straight while tensioning. Always release backstay tension before adjusting luff extrusion. Tensioning the luff extrusion with the backstay tensioned can damage the luff extrusion joints when the backstay tension is released. 4.2 Rig tuning Furling in and out will work best on a mast tuned with limited pre bend. Read 595-540-E Hints and Advise for tuning instructions. -
Page 16: Outhaul Car Stop
4.3 Outhaul car stop The position of the outhaul car stop on the boom will affect tension in the sail foot and leech. E.g. if the outhaul is posi- tioned too far aft, the force from the outhaul clew will keep the foot tighter than the leech which can cause the sail to jam in the top of the mast. The ideal position can vary between boats due to rig, sail and batten designs. It is recommended to place the outhaul stop 500 mm from the aft mast wall as default, and then adjust it forward or aft if necessary. 4.4 Outhaul routing Examine outhaul car and outhaul turning points for excessive friction. Replace old and worn blocks if needed. Outhaul routing with as low friction as possible will improve the unfurling process. Synchronized outhaul winch The force limit in the synchronized outhaul winch is based on the line force at winch entry. High friction in the outhaul routing will result in the actual force in the outhaul clew being significantly lower than at the winch, which can negatively affect the synchronization. -
Page 17: Sailing With Synchronized Main Furling
Sailing with Synchronized Main Furling 5.1 Preparations for furling and unfurling There are many factors to consider for a successful furling operation. Get familiar with the furling system in light conditions and pay attention to the following details before furling out and in. How important these adjustments are for the furling result can vary between boats, sail designs and other factors. SAIL UPWIND Sail upwind. RELEASE BACKSTAY Release backstay tension (if very tight) to straighten the mast. Adjust the boom angle to keep the leech tight and battens parallel to mast. Use kicker/topping lift. ADJUST BOOM Ease the main sheet. ANGLE EASE MAIN SHEET Always observe the entire furling process! Stop immediately in case of any issues. Ill. Dan Ljungsvik/Seldén 2018 Keep away from the sail groove, winches and any other moving parts during furling. -
Page 18: Unfurling
5.2 Unfurling Apply and secure the outhaul to the synchronized electric winch. Press “Furl Out”. The outhaul winch will make a short warning signal before starting to run. Remote control of a sailing winch is hazardous. Always observe the unfurling process and ensure nothing can interfere with the winch, outhaul line or sail groove in the mast. Whilst holding down “OUT”, press the second button to increase the speed, if wanted. Full sail Hold button(s) pressed. The synchronized system The motor will make a short rotation will recognize a fully unfurled sail and stop automa- when unfurling is finished, to activate tically. the break mechanism. Reduced sail area Release button(s) when sail is in desired position. If needed, the outhaul can be trimmed using the winch buttons. Be careful when using the winch buttons, as this activates the full power of the winch. Ill. Dan Ljungsvik/Seldén 2018... -
Page 19: Furling
5.3 Furling Free the outhaul and keep it tensioned (about one turn on the winch). Press “IN” and simultaneously slacken the outhaul line while the sail is reefed. Whilst holding down “IN”, press the second button to increase the speed. Release the button(s) and stop reefing at desired sail area or when sail is fully furled in. The motor will NOT automatically stop during furl in. Run the last turns with low speed and keep attention to the position of the outhaul block to prevent it from being pushed into the sail groove and damage the mast. 5.4 Furling without synchronized winch If the synchronized winch is not to be used, the outhaul can be pulled manually without disconnecting the furling mast motor. 1. Press and hold “MAIN OUT”. The mast motor will start to rotate but pauses automatically if the outhaul is not pulled, to avoid the sail being unfurled inside the mast. 2. Keep “MAIN OUT” button pressed. Pull the outhaul manually. The furling motor will start to rotate when it detects that the outhaul is being pulled. Proceed until desired sail area is reached. When OUT button is released, the mast motor will activate the rotation break. -
