The magnet must be fitted into a tooth in the top of the chainwheel
so that the anchor rode passes between the magnet and the sensor.
See Fig 11.

Magnet
Magnet size for any installation depends on the gap that can be achieved. (Refer to Table of Gaps on PAGE 5). Some
windlasses will be pre-drilled for the magnet.

Magnet Installation for Horizontal Windlasses Using Rope/Chain Rode
CONSOLe UNIT INSTaLLaTION
Choose a position where the operator will be able to see the anchor and windlass when using the AA550. The console should
be mounted on a flat surface at least 3 ft (1m) away from any equipment transmitting or cables carrying radio signals eg VHF
radios, cables and antennas or radar antenna and at least 6 ft (2m) away from any SSB equipment. The front of the console is
waterproof but the cable boot on the back is designed to breathe. The console should be mounted so that the back is protected
from moisture. There are 4 holes required to mount the console. Refer to the drilling template supplied for the hole sizes and
positions. Do not use sealer or glue. The rubber grommets will seal the unit. Do not use metal studs, nylon bolts are supplied.
These should be hand tightened only.
Multiple Console Unit Installation
Two AA550 consoles can be installed to provide multiple control stations. The AA550 can also be installed with other windlass
control stations eg deck switches or plug in hand controls and other AutoAnchor products the AA150 and the AA601. Refer to the
wiring diagrams and/or your supplier for details.
Refer to the Wiring Diagrams for wiring installation detail. The cable specifications on page 2 of these instructions must be
followed. Interlock protection is included in the system. Do not fit diodes or interlock devices as these will prevent the
system from operating correctly. All battery and motor cables must be ring type, insulated to prevent short circuits and installed
no closer than 1 ft (300mm) away from the sensor head. To reduce the potential for interference all cables must be located at
least 1.5ft (500mm) away from any equipment transmitting or cables carrying radio signals eg VHF or SSB radios, cables and
antennas or radar antennas. Insulation must be used to protect all terminals. Do not leave cables hanging loose, they must be
tied in place with cable ties.

Power Supply & Wiring Connections
1.
12V or 24V DC power supply is required to the AA550 console.
2.
Power to the AA550 and all windlass controls eg. toggle switch, remote switches, deck switches must be supplied from
one point or the AutoAnchor will be damaged. See the diagrams below.
3.
The power must be disconnected when installing and connecting the wiring.
4.
Check battery polarity before connecting power and ensure output terminals will not short.
5.
A 5 Amp resettable isolating/breaker switch to shut off power to the AA550 and the windlass must be installed
in a position easily accessed by the AA550 operator.
6.
Multiple battery bank negative terminals must be permanently connected together to become the common negative
return (ground).
