3.2 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.

3.1 Installing the magnet on the anchor windlass

On a few models of anchor windlass the sensor and the magnet are already installed
(chain counter setting).Therefore, the operations described below are not necessary.
1. A hole having a diameter of 6.5 mm (~1/4") and depth of 8 mm (5/16") must be drilled on a
tooth of the gypsy, in a place outside the chain's path.
2. In the case of horizontal shaft anchor windlasses (see Fig.), drill the hole in the outer
circumference of the gypsy.
3. Also make sure that the protruding part of the magnet will not collide with the base or sensor
during rotation of the gypsy.
4. Insert the metal part of the magnet in the hole, allowing the protected part to protrude by about
2 mm. Fix it in place using an adhesive for metals (two component epoxy glue) or silicone. The
glue used must be able to withstand a marine environment.
