The product requires a 12V or 24V battery, installed in the boat. Use cable colour and standard for positive and negative cables in the boat. It is recommended to enable turning off the power from the cockpit.

Power supply & SEL-Bus system

Seldén’s electrical power system can be connected to a voltage level between 10-30V and will deliver the required power up to 1000W. The Power Supply Unit (PSU) amplifies the voltage to between 40-48V, just below the limit for high voltage regulation which is at 50V. The electrical system is equipped with a diagnostic system, with error codes being presented by flashing LED’s on the PSU and Motor Control Unit (MCU). The PSU, MCU and control button(s) are connected through a Can Bus, referred to here as a SEL-Bus. The SEL-Bus system is used for communication between the units, enabling a diagnostic function and allowing the system to reduce power consumption by putting the system into sleep mode when not in use. During sleep mode there is a small amount of electrical consumption, making it important to switch off the main switch when not using the boat to avoid draining the battery.

Caution: The SEL-Bus is a standalone system and shall not be connected to any other Can-bus system on the boat, for example the NMEA 2000

Installation

Preparing the installation
Mount the PSU and MCU, respectively, at a place and position in the boat which fulfills the following criteria:

• PSU is positioned close to battery.
• MCU is positioned close to its respective Seldén Motor Unit. Max allowed cable length of connection cables (grey, orange, brown) is 3x5m.
• PSU and MCU are positioned in a dry place.
• PSU and MCU are positioned so that the cable can form a drop loop. This is to prevent water ingress.
• The PSU and MCU need to be positioned so it will be possible to read any error codes from the LED indicator (see position of LED indicator in illustration to the right) and so that it is possible to read the unit’s ID-label through the transparent lid.
• The PSU and MCU are positioned so that the fuses under the lid can easily be replaced.
• Have in mind that other systems that are already installed in your boat might be affected by the new electronic equipment. Do not install the PSU, MCU and wires close to devices that are sensitive to magnetic interference (e.g. compass, antenna, GPS-receiver).
• All components of the SEL-Bus system (T-connectors, terminals etc.) should be installed in an accessible position which enables inspection and replacement.

Note

• Install the units in a dry place which prevents water ingress.
• Do not install the units in the engine compartment or in any other high temperature area.

Installing the 12/24V cable and main switch/fuse.
The main switch and fuse function should be installed between the battery and the PSU. If a custom switch/ fuse option is used (other than the ones that are provided in Seldén Start pack for 12V and 24V) use one of the following two alternatives with fuse size listed in table below:

• High current integrated fuse switch
• High current switch and fuse

Battery system

12V| 100 A (Fuse with time delay)| 120-160 A (Fast acting fuse)
24V| 50 A (Fuse with time delay)| 60-75 A (Fast acting fuse)

Install the switch/fuse and PSU to the battery using cables of the same quality and colours as standard in your boat. The required cable size depends on the battery power and the total length of positive and negative cables in the Battery/PSU-circuit. The cable sizes are listed in the table below:

Important: Turn off the battery switch before connecting the battery and PSU

Connect the 12/24 V circuit as outlined below.

Note: It is recommended to use a remotely controlled main switch to be able to turn off the power from the cockpit.

Installing the PSU and MCU

Note: Turn off the battery switch before connecting the PSU and MCU.

Connect the MCU to the PSU using Seldén recommended colour coding:

• Positive cable (connected to +VBUS): Dark blue
• Negative cable (connected to -VBUS): Yellow

For the required cable area between the PSU and MCU, use a cable dimension corresponding to table below (calculate as the sum of positive and negative cable lengths):

Cable dimension (cross sectional area)| Recommended max length (positive and negative cable)
---|---
6mm2| 18m
10mm2| 40m

If multiple Motor Control Units are used, the additional MCUs can be connected in parallel either directly
to the PSU or via another MCU. The different wiring options may require different cable lengths and cable sizes. Example of calculation of required power cable size for systems with multiple motor control units:

| MCU A

Total cable length is 2×8 m = 16 m.

Use power cable size 6 mm2.

---|---
MCU B and C

Total cable length is 2x5m + 2×6 m = 22 m.

Use power cable size 10 mm2.

PSU wiring

1. Unscrew the 5 Torx head screws (T20) of the PSU lid, highlighted in the image to the right.
2. Remove the lid to uncover the connectors.
3. Install the cable from the positive terminal on the battery, to the connector marked +BAT. Fasten the cable.
4. Install the cable from the negative battery terminal to the connector marked -BAT and fasten the cable. Use cable colour as standard in the boat.
5. Install the dark blue cable from +VBUS on the PSU to +VBUS on the MCU.
6. Install the yellow cable from -VBUS on the PSU to -VBUS on the MCU

MCU wiring

1. Unscrew the Torx head screws (T20) to open the lid of the MCU units in the same way as on the PSU.
2. Connect the positive dark blue cable from the PSU to the connector marked +VBUS and the negative yellow cable to -VBUS. Fasten both connections.
3. To install more MCU’s, connect in parallel to either the PSU or MCU, to get the easiest wiring.
4. Finally, connect the connection cables from the Seldén Motor Unit to their respective connector (L3, L2, L1) of the MCU.
   Note that the position of connection cables may vary between different motor units. Carefully follow the label or pairing instructions in each respective drive unit manual.

Installing the push buttons
A SEL-Bus converter is used to convert signals from the push buttons to the SEL-Bus system CAN protocol.

Note: The push buttons need to be connected to the correct SEL-Bus converter: Furlex, Winch = 532-827-01 Furling mast = 532-827-02

1. Find an appropriate position for the SEL-Bus Converter; close to buttons and protected from the weather and so the LED indicator is visible during inspection.
2. Cut the green and red cables included in the SEL-Bus converter to the appropriate length. Attach the press cable connectors included in the Push button kit.
3. Connect the green cables to “out”/”first speed” button, using the correct terminal positions as described in respective push button instruction.
4. Connect the red cables to “in”/”second speed” button, using the correct terminal positions as described in respective push button instruction.
5. Back lightning, which is optional, is connected to terminal positions as described in respective push button instruction. The lighting is preferably connected to the nav-lights switch. Use the colour coding and cables as standard in your boat.
6. Install the push buttons. Hole dimensions are found in each respective push button instruction.

Caution: Place and orientate the push buttons so that risk of unintentional activation (e.g. from standing/sitting) is low.

SEL-Bus system
Important: Keep the battery switch turned off until all SEL-Bus cables are installed

The SEL-Bus network communicates between the PSU, MCU and control buttons, and provides these units with information. The network uses a “backbone” as a main communication cable that is routed along the boat and “drop cables” to connect the PSU, MCU and control buttons. The SEL-Bus network works in series, which allows the network to be easily expanded.

The SEL-Bus system

• T-connector (A): A three-way connector with 1 male and 2 female connectors. The T-connectors are used to connect drop cables from the unit(s) to the backbone.
• Male (B1) and female terminal (B2): A 120-ohm resistor at each end of the SEL-Bus backbone. The terminals are essential for a secure signal.
• Backbone (C): The main communication cable. Must start and end with end terminal B1 and B2.
• Units (D): Any system connected to the SEL-Bus via a drop cable. These units are the PSU, MCU and control button(s).
• Drop cable (E): The cable connecting a Unit to the backbone. Max. length of 5 m.

Note

• The total length of the SEL-Bus network (backbone + drop cables) must not exceed 70m.
• An existing SEL-Bus system can easily be expanded with additional units at any time.

Installing the SEL-Bus cable

1. Start at one end of the backbone. Connect the male terminal to the T-connector.
2. Connect the drop cable from the first unit to the T-connector.
3. Connect the first backbone cable to the T-connector.
4. Connect a new T-connector to the end of the first backbone cable.
5. Repeat step 3-5 for every additional unit (PSU, MCU, control buttons) to be connected to the backbone.
6. Finish by connecting the female terminal to the end of the backbone.

• T-connectors can be connected directly to each other.
• SEL-Bus cables can be connected directly to each other. Example: 2x 5m SEL-Bus cable can be used as 1x 10m.

Configuration of the control button to the SEL-Bus network.
To configure the control buttons to the SEL-Bus network, the configuration button on each respective MCU is used. The configuration button is located under the transparent lid, behind the LED and next to the control chip.

Note

• Use a non-metal pin to depress the configuration button.
• MCU must be connected to motor unit (chapter 2.3) before control buttons can be configured.
  Config. Button| Mode| LED Indication| Action
  ---|---|---|---
  Press one time| Button configuration mode| Violet| Press primary set of control button to link it to the MCU.
  Press one time after first configu- ration.| Button configuration mode +| Violet| Add set of buttons to the same MCU (e.g. auxiliary control buttons B)
  Press two times| Reset configuration memory| Violet then green| Erases earlier configurations. No button sets are now linked.

Primary buttons
Repeat for each Motor unit (with respective MCU and control button set)

1. Turn the main switch on and wait until the LED on the PSU and MCU turn green.
2. Push the configuration button on the MCU, the LED will turn violet.
3. Push and hold either one of the two buttons in the control button set (in/out or 1/2) for approximately 5 seconds until the motor unit generates a start-up signal.
   Buttons are now ready to use.

Auxiliary buttons
It is possible to add a second set of control buttons to the same motor unit, to enable control from various positions. This can be done in two ways:

Warning: Remote control of motorized sailing equipment can be hazardous and require full attention on the motorized unit while in use.

Synchronized Main Furling
To configure the control buttons (winch and main) to electric furling mast with synchronized outhaul, the configuration should be done in the following order. Remember to reset the configuration memory if the MCU have been configured to control buttons before.

Note: It is recommended to disengage the motor unit from the manual furling gear (using the clutch) during configuration.

Operation

• The PSU and MCU have a LED that indicate the status of the system.
• When the main switch is turned on, the LED turns blue which indicates the PSU and MCU are active and running a start diagnosis. After 5-15 sec the LED changes to green which indicates that the system is working normally and is set to energy saving stand-by mode.
• When a control button is pushed and a motor unit is running, the system is activated and the LED turns blue. The LED turns green again after 5-15 sec.

Note: Always turn off the system when not in use.

Troubleshooting

Network fuses

The Power supply unit and each Motor Control Unit have fuses installed under the plastic lid. Use standard blade fuses of correct current rating if they need to be changed.

Power supply unit

• 3A/5A: Fuses for the SEL-Bus network. Blown fuses will cause communication failure on network.
• 30A: Power input fuse. Blown fuse will show a green LED indicator on PSU while the other units on the network will be dead (no LED light).

Motor Control Unit

• 30A: Power input fuse. Blown fuse will cause the MCU to be dead (no LED light). The other units in the network will work normally.

Fault codes

If the system experiences an error, it will display this via the LED located next to SEL-Bus output on both the PSU and the MCU. If the system has recently been started it can take up to a minute for the system to start indicating fault codes.
The power supply and the control unit each have their own set of fault codes. The codes are divided into two different categories, warning codes and error codes. The system will continue to indicate fault codes until turned off. If multiple faults are detected the system will indicate these after each other.

Warning codes (flashing white)
The LED will indicate the warning codes by flashing white.

Error codes (flashing in alternating colors)
Error codes indicate a more serious problem with the system, such as a hardware fault. The system will indicate these by alternating the colour of the LED.
If, for example, the PSU cannot find any Motor Control Units on the SEL-Bus network, the PSU will identify this as a SEL-Bus cable/network error. The LED of the PSU will flash two times before briefly pausing and repeating the sequence, indicating warning code number 2. If another fault is detected, e.g. memory chip error, the LED will first flash two times in white, pause, then flash red-white-green before pausing and repeating the sequence again.

Note

• Write down the code before you shut down the system, as the code will not be memorized.
• Fault codes and troubleshooting are continuously updated. For latest version, please visit www.seldenmast.com

SEL-Bus converter and buttons inspection.
The red LED indicator on the SEL-Bus Converter indicates that the converter is working properly and is installed to the SEL-Bus network. The indicator will light 5 min after the system is turned on and 5 min after each time any of its respective buttons have been activated. Trouble shooting for non-working control buttons:

according to section 2.7
Bad connection between SEL-Bus converter and MCU.| Check fault codes on corresponding MCU (section 4.4) and combined fault codes for network component inspection (section 4.6).
Bad connection between button and SEL-Bus converter.| Keep system power on. Wait for LED to go out (5 min).

Push control button. If LED stays out, connection between converter and button is bad. Check cables, connections and if fault persists change push buttons.

LED indicator is off| Bad connection between SEL-Bus conver- ter and SEL-Bus network. (No power)| Check combined fault codes for network component inspection (section 4.6).
Bad SEL-bus converter| Change SEL-Bus converter.

SEL-Bus network error – component inspection
Read the fault codes on every unit (PSU, MCUs and SEL-Bus converters) connected to the SEL-Bus network. By combining the fault codes on all units, it will be easier to locate where on the SEL-Bus network the problem is. Turn off and on the system one time before starting this trouble shooting. Remember that LED indicator on SEL-Bus converter turns off after 5 minutes of inactivation.
Following is a guide of where in the SEL-Bus network to find the possible failure (“X”). Failure can be caused by defective SEL-Bus cable/cable contacts or defective adjacent T-connectors. Ensure that the contacts are properly connected and exchange components if necessary.
