In order for the chain counter to measure the exact length of the chain, it has to count the number of rev-
olutions completed by the gear that drives the chain (gypsy). A laps sensor kit is supplied with the chain
counter. This kit includes a cylindrical magnet, a magnetic field sensor and two plastic adaptors to be used
to secure the sensor in place. The magnet is to be secured to the gypsy while the magnetic sensor is to be
fixed to the windlass base.
The standard installation procedure is described below. Unfortunately we cannot describe a procedure ap-
plicable to all types of situation. Adapt this procedure to satisfy your own individual requirements.
