2.4 Installing the magnetic sensor for horizontal shaft anchor windlasses

(see Fig. 2A – 2B – 2C)
Drill a 4 mm (~3/16") hole in the cover through which to thread the sensor cable. Fasten Part A of the support with the two screws
provided, after having positioned the O-ring in the lower part of the support. Cut Part C to measure using a hacksaw. The sensor must be
positioned at a distance of about 3 mm (~1/8") from the magnet. Fit Part C with the magnetic sensor on support A and fix it in place using
an adhesive for plastic (two-component epoxy glue) or silicone. Using the same glue, attach the sensor to Part C.

2.5 Installing the chain counter

The chain counter must be positioned so that the display will be easy to read. It should not be exposed to direct sunlight. Secure the
instrument in place with the bracket provided, tightening the two screws using a cross screwdriver.
For instructions on making electrical connections, see the attached diagram. The wires must have a minimum cross section size
of 1.5 mm². Install a 4 A (ampere) fast safety fuse on the + wire of the battery. Do not use the voltage generated by the engine battery
set to provide power.
The instrument complies with EMC standards (EN55022) and must be positioned at a distance of:
- 30 cm (~1 Ft) from the compass;
- 2 metres (~6.5 Ft) from radio transmitter equipment;
- Transmission frequency 2,4GHz
