2.1.7 INSTALLATION VERTICAL WINdLASS - ROPE & CHAIN
Refer to the Overview Notes on page 3 before starting installation.
For an accurate rope and chain count, the rode must run between the sensor and
magnet. If your windlass is prefitted with a magnet in the bottom of the chainwheel you
need to remove it and fit a new magnet in the top of the chainwheel. Refer to Figs 2-4.

Magnet Size: 10mm X 8mm magnet (#9061). An 8mm x 6mm magnet (#9052) may be
used on smaller windlasses. Check with your supplier.
Magnet Fit: Some windlasses are predrilled and others need a special fit. Please check
with your supplier. The usual fit is as follows: Drill a hole 10.3mm (13/32") diameter and
9.5mm (3/8") deep into a spoke in the top of the chainwheel. Cover the magnet with a
minimum of 1mm epoxy. The magnet and sensor must be aligned so that the anchor rode
passes between them.(See Figs 2 & 3).
Sensor Position: The sensor must be fitted into the deckplate within the sensor position
range at the stern end of the windlass (See Fig 5). It must also be aligned with the magnet
so that the rode passes between the sensor and the magnet. The centre of the magnet
and the centre of the sensor may be up to 10mm out of direct alignment. (See Fig 3). The
gap between the sensor and magnet must be as per the table below.

Sensor Connection: The AutoAnchor
plug and play sensor extension cable
must be used to connect the sensor
to the console unit. Ensure the
connectors are firmly screwed together.
See the information on page 4.
Loose cable should be tied in place
with cable ties and kept clear of
chain.
2.1.8 INSTALLATION HORIZONTAL WINdLASS - CHAIN ONLy
Refer to the Overview Notes on page 3 before starting installation. It is not
possible to set out a single installation method for horizontal windlasses.
The sensor may be fitted inside the windlass or you may need a sensor
holder (Part #9070). See Fig 6 below. Often the sensor and magnet can only
be fitted by the windlass manufacturer.

Magnet Size: 6mm x 4mm magnet (#9009).
Magnet Fit: If your windlass is not predrilled drill a hole 6.5mm (1/4") diameter and 5mm
(3/16") deep in the edge of the chainwheel. Cover the magnet with a minimum of 1mm
epoxy.
Sensor Position: The AutoAnchor sensor may be fitted using a sensor holder fixed to the
deck to sit under the chainwheel (See Fig 6). The AutoAnchor sensor holder (#9070) is not
included in the standard kit. Check with your supplier if you need this. The AA black sensor
and the reed switch sensor must be fitted directly in line with the magnet in the chainwheel.
The AA grey sensor may be fitted up to 20mm out of alignment. The gap between the
sensor and magnet must be as per the table below.
