Installation
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.
Installing the magnet on the anchor windlass
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 gipsy, in a place outside the chain's path.
In the case of vertical shaft anchor windlasses (see Fig. 1B), drill the hole in the lower circumference
of the gipsy.
In the case of horizontal shaft anchor windlasses (see Fig. 2B), drill the hole in the outer
circumference of the gipsy.
Also make sure that the protruding part of the magnet will not collide with the base or sensor during
rotation of the gipsy.
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.
Installing the magnetic sensor for vertical shaft anchor
windlasses
(see Fig. 1A – 1B)
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.
Fit Part B with the magnetic sensor on support A and adjust its height until
it is aligned with the magnet fastened on the gipsy.
Bring the sensor to a distance of about 3 mm (~1/8") from the magnet
and secure it in place by tightening screw G1. Then tighten screw G2.
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.
