Safety precautions
Choosing the correct version of furler for your boat:
The key to a safe and properly working installation is correct dimensioning in relation to the boat size the
products shall be used on. Seldén provides dimensioning guidelines in catalogues, leaets and on the
website. If there are any questions about selecting the right product, please consult an authorized Seldén
dealer. All dealers are listed at www.seldenmast.com.
Safety notes regarding the electrical installation for the CXe:
-The installation should be done by a person with marine installations skills. You can nd your local
authorized Seldén dealer at www.seldenmast.com.
-CXe is controlled only by Seldén’s 42V motor drive system.
-Make sure the system is switched o before performing any installation or service.
-Never modify the electric system of your CXe or its installation drawings - installation, alterations
and maintenance should be performed by a competent marine electrician.
-Never alter or modify the rated current amperage of overcurrent protective devices.
-Never leave the craft unattended with the CXe energized.

2. CXe
CXe is a two-speed electric furler for Code sails and with a Selden tack adaptor also for top-down furling
gennakers. CXe is available as an on-deck (designated OD) and through deck installation (designated TD).
Low power consumption
High eciency throughout the electric power and control system. A “sleep mode” is activated to save power
when not in operation.
Powerful enough, but with precise torque limitation.
The electric motor has a computerised controller that monitors the current draw precisely. As soon as it
reaches a pre-set level it cuts out quickly enough to avoid damage to components. The torque level is
programmed into a memory chip.
Resistant to the marine environment
CXe uses anodized 6000-series aluminium components. Plastic components are PC and PA, glass bre
reinforced and UV stabilized. The motor and reduction gear operates in the oil lled and sealed aluminium
housing. The drive units are individually pressure tested before delivery.
A double seal between deck collar and drive unit prevents water intrusion (TD)
Two speed operation
A double control button makes it possible to operate the furler with great precision in the low speed mode.
By pushing both buttons at the same time, high speed is activated.
Limited brake
The reduction gear and motor gives a limited brake function but will not protect against involuntary unfurling.
See chapter 8 for more information.
Compact size. Minimized weight and dimensions.
The electric motor is compact, still giving enough power. This is made possible by raising the voltage up to
42V. Keeping weight and the dimensions in focus during the design has resulted in a small unit.

2.2 Control pack
CXe is used together with the Seldén Power supply and SEL-Bus system. The drive unit is connected to a
motor control unit (MCU), which enables communication with the power supply unit and the OUT/IN push
buttons. The CXe is either connected to an existing SEL-Bus system onboard (only requiring an additional
MCU (Motor Control Unit), push buttons and SEL-Bus converter) or sold as a complete system.
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. For installation of the Power Supply
and SEL-Bus system, see installation guide 597-275-E. System illustration.

4. Installation
4.1 Fitting the deck collar
1.
Adjust the hole for deck collar if necessary.
Fit should be as tight as possible. Adjust hole
with putty if necessary. Use release agent or
tape on deck collar if used as template.
2.

fully.
4.2 Fitting the drive unit
1.
Insert the drive unit from below

13
2.
Make sure the brackets fully mate with the
mounting surfaces in the deck and that there is
no interference between the drive unit and the
deck. Adjust if necessary. Check that the top
surface of the drive unit is slightly higher than
the top surface of the deck collar. (A)
3.
Mark out the positions for the 4 bracket screws
with a pen.
4.
Remove the drive unit. Drill and tap the four
holes M8 or 5/16. 20 mm full thread min (drill
depth ~25 mm)
5.
Test t the drive unit with all four screws.

mating surface of the deck collar with solvent.
Apply caulking around center hole and screw
holes. Also apply caulking to loop and t it in the
recess in the deck collar.
2.
Fit the collar, loop and screws. Using caulking
or other compound under the screw heads will
prevent corrosion.
Wipe o any excess.

15
4.4 Assembly of the drive unit
1.
