WARNING This symbol indicates a potentially hazardous situation. If not avoided, this could result in serious personal injury or damage to property. Turn off the electric power during installation of the electrical equipment. Turn off the electric power when the system is not in use to prevent unintentional activation. Always monitor the entire furling process! Stop immediately in case of malfunction. Keep body parts away from the sail groove, winches and any other moving parts during operation. The electric motor can be disengaged and engaged by shifting the clutch plungers positions between ELECTRIC and MANUAL. When set to MANUAL, use a winch handle in the winch handle socket to manually operate the furling gear.

Page 6: Power Supply And Sel-Bus System
2.2 Power supply and SEL-Bus system The mast motor is used together with a Seldén Power supply and SEL-Bus system. For synchronized outhaul (SMF), a Seldén electric winch is also required. The mast motor is connected to motor control unit (MCU) for furling masts. Via the SEL-Bus network, the fur- ling mast MCU can communicate with the winch MCU and OUT/IN control buttons. Seldén’s electric winch, all power supply and SEL-Bus system parts are sold separately. Parts and packages are described in Seldén Power Supply and SEL-Bus system: Order guide 597-283-E. System illustration The illustration shows an example of a Synchronized Main Furling network installation. The complete Power Supply and SEL-Bus system of each customer will vary and can include additional units and functions. 1. Battery (not included) 6. Motor Control Unit (MCU), Electric winch 2.

Page 8: Connection To Seldén Power Supply And Sel-Bus System
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 the 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. 3.1 Configuration of control buttons for Mast motor with synchronized outhaul cylinder (HPS).

Page 10: 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. Lift/disconnect the locking tube from the tack assembly. Grip the luff extrusion with your hand at the upper access hole. Disconnect the motor and use the emergency winch function to tension the luff profile until you can not stop the extrusion from rotating with your hand. Note! Do not use the motor for tensioning as you risk injury if your hand gets caught. 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 prebend. Read 595-540-E Hints and Advise for tuning instructions. -
Page 11: 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 fric- tion 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 12: Sailing
Sailing Both clutch plungers should be in their lower position. 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 with the vang to keep the leech tight and battens parallel to mast. Use kicker/topping lift. ADJUST BOOM ANGLE Ease the main sheet. EASE MAIN SHEET Always observe the entire furling process! Stop immediately in case of any issues. Keep away from the sail slot, winches and any other moving parts during furling. Avoid reefing to a position where the battens are riding on the sail slot. Ill. Dan Ljungsvik/Seldén 2018... -

Page 16: Manual Drive
5.5 Manual operation In case of electric or mast motor failure, the sail can be manually reefed by engaging an emergency gear and disconnecting the electric drive unit. Disconnect mast motor Turn power off! Insert emergency handle on starboard side of mast. Turn the handle any direction as you pull the upper lever (A) aft and up. You might have to turn up to 10 turns to get the clutch find it´s position and allow connection of the manual drive. The luff profile is now connected to the handle socket via a worm gear, and the electric drive can be disconnected. To disconnect the electric drive, pull the lower lever (B) aft and up as you turn the winch handle slightly clockwise to unload the connection between electric drive and luff profile. You can now use the handle to furl the sail in and out. The gear has a high ratio so it takes a lot of turns on the handle. A power tool with 1/2” socket is therefore a good option. Remove winch handle from socket when done. -

Reconnect electric motor Turn the handle any direction as you pull the lower lever (B) aft and up. Up to 10 turns on the handle might be required to find the correct position for the clutch to engage. Pull the upper lever (A) aft and down as you turn the winch handle slightly clockwise to unload the connection between manual gear and luff profile. When both levers (A&B) are in their lower positions the sail can be controlled by the electric drive. 5.6 Unfurling with manual winch and electric mast motor. 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 brake. -

Page 19: Service And Maintenance
Service and maintenance Always keep the manual furling system in good condition, following the service and maintenance procedures described in each respective manual furling mast instruction. 7.1 Annual maintenance Lubricate motor brake There are two different layout options, one with a separate motor cover (to the left) and one without (to the right). Remove the screw to the lubrication hole, A. This can be accessed via the sail opening or by removing the motor cover. To enable removal of the motor cover, the mast should be straight and the rig tension released. Apply WD-40 in the hole and simultaneously rotate the mast motor minimum one turn. Remount screw. 7.2 Extended maintenance Professional service should be made on the mast motor every 5th year. Contact an authorized Seldén dealer for service management. -
