SKT ST4000 jõuühiku uuenduskomplekt MkII-le

The Raymarine E12093 update kit is designed to modernize existing ST4000 autopilot systems. It replaces the old power unit with a Mk II wheel drive, integrating the technology from Raymarine's Evolution autopilot range. This kit aims to improve the performance of the helm control unit and extend the lifespan of ST4000 systems.

The drive unit provided in this kit is compatible with spokes in 3, 4, 5, 6, 7, or 8-spoke wheels.

The drive unit has a front cover diameter of 228 mm (9.0 in) and an overall diameter of 361 mm (14.2 in). Its height is 135 mm (5.3 in). The motor tube has a diameter of 48 mm (1.9 in) and a length of 171 mm (6.7 in), requiring an additional 60 mm (2.4 in) clearance for the cable.

No, this kit is a targeted upgrade. It replaces the power unit with a Mk II wheel drive and integrates with the existing ST4000 autopilot controller, but does not constitute a complete system replacement.

The E12093 kit includes the following items:

The wheel drive unitA pedestal mountThree 16 mm spoke clamping insertsThree 12 mm spoke clamping insertsSix spoke clampsSix M5 x 16 mm clamping screwsFour #10 x 3/4 in support screwsA 6 mm drill bitA 4 mm drill bitA 3 mm Allen keyTwo ball jointsA tiller pinThree #8 x 3/4 in button-head screwsOne studTwo nutsTwo #8 x 3/4 in countersunk screwsA 4.5 m (15 ft) power cableOne cable clip and a #6 x 1/2 in screw

Installing the drive unit involves four main steps:

Drilling the spoke clamping holes in the front cover.
Mounting the drive unit to the wheel.
Mounting the pedestal bracket.
Connecting the drive to the existing control unit.

The unit is designed to operate with steering systems having between 1 and 3.5 turns lock-to-lock.

Yes, the cover must be removed from the drive wheel unit. The cover is held in place by three "push-fit" posts that insert into three sockets on the drive ring. To remove it, hold the motor with one hand and pull the cover upward and away from the drive unit.

The spoke holes are numbered inside the cover. Position the cover arrow upwards and refer to the diagrams in the manual to identify the correct locations based on your wheel’s number of spokes (for example, for a 5-spoke wheel, drill the 4 holes marked '5'). It is recommended to mark the holes and check their alignment by placing the cover against your wheel.

Raymarine’s EMC installation guidelines recommend using the cables specified by Raymarine. Cutting and reconnecting these cables can compromise EMC performance and must be avoided unless detailed in the installation manual.

Yes, it is crucial to ensure that the electrical power is cut off before making any electrical connection for safety reasons.

Yes, although the product is supplied with default settings, it is necessary to complete the commissioning procedures detailed in the "Commissioning" section of the relevant autopilot controller manual to ensure optimal performance on your sailboat.

To register your new Raymarine product, you can do so on the Raymarine website at www.raymarine.com/warranty.

For optimal EMC performance, Raymarine equipment and connected cables should be:

At least 1 meter (3 feet) away from any equipment transmitting or cables carrying radio signals (e.g., VHF radios, cables, and antennas). For SSB radios, this distance should be increased to 2 meters (7 feet).More than 2 meters (7 feet) from the path of a radar beam.Equipment should be powered by a separate battery from the one used for engine starting, to avoid voltage drops and starter transients that could cause equipment to reset.

This kit integrates Raymarine's Evolution autopilot technology into an existing ST4000 system by replacing the power unit with a Mk II wheel drive.

The kit is specifically designed as an "ST4000 power unit upgrade kit to MKII" and integrates with the existing ST4000 autopilot controller. No compatibility with other controllers is mentioned.

The kit includes a power cable with a length of 4.5 meters (15 feet).

Yes, the kit includes a 6 mm drill bit and a 4 mm drill bit, as well as a 3 mm Allen key, required for certain installation steps.

The pedestal mount is a component included in the kit, essential for securing the drive unit to your boat's helm column, ensuring stable and secure installation.
