The magnet and sensor must be installed correctly or the AA550 will not work. If it is not possible to comply with these instructions
please check with the AutoAnchor manufacturer or your supplier as special fitting instructions may be available to assist for
non-standard fittings. Some windlasses are predrilled for sensor and magnet fitting.
If fitting the aa550 to a horizontal windlass, check with your supplier or the autoanchor manufacturer, (contact details on
Page 9) to confirm the autoanchor can be fitted to your windlass.

drilling the deckplate:
If the windlass is not factory drilled or you do not have a template you will need to drill a hole 13/32”
(10.3mm) diameter through the windlass deckplate. The hole must be within the sensor position range at the stern end of the
windlass (See Fig 1 on PAGE 3). The sensor must also be aligned with the magnet so that the rode passes between them. The
centre of the magnet and the centre of the sensor may be up to 10mm out of direct alignment. (See Fig 2 on PAGE 3)
Sensor Installation for Vertical Windlasses Using Rope/Chain Rode
The aa550 must be fitted using the custom designed electronic sensor supplied in the kit. It will not work with any other
sensor.
The sensor is fitted into the windlass deckplate.
If counting rope/chain, you must have a minimum of 10ft of galvanised steel chain on your rode.

Windlass & anchor Specifications
The AA550 is designed for use with the rope/chain windlasses listed on the pre-programmed list enclosed with the Operation
Manual. It can be used with all-chain windlasses using the custom setting. The windlass must be installed according to the
windlass manufacturer’s instructions with the correct size rope and chain for the windlass chainwheel. The AA550 will not count
correctly if the windlass is not standard (eg it is installed with a different chainwheel or motor). For smooth operation the windlass
requires a good quality, properly fitted bow roller and a swivel should be connected to the anchor where it joins the chain.

Note:
Short circuit protection is required on these cables. The load sensor terminators supplied have motor terminal connectors
and a 1000 Ohm resister prefitted. If these terminators are not used a 100mA fuse must be fitted.
Cable from aa550 console to the batteries and solenoids:
Note:
All battery cables must be ring type.
This specification is based on the total cable length measured from the battery to the console plus from the console to the solenoids.

The AA550 meets and exceeds the CE standard for EMC (EN60945). These standards are intended to provide reasonable
protection against interference by other emission generating products on the boat. However, compliance with these standards
is no guarantee that interference will not occur in a particular installation. The installation instructions must be followed to
minimise the potential for interference. AA550 equipment must be installed to maintain the following distances away from any
equipment transmitting or cables carrying radio signals eg VHF or SSB radios, cables and antennas or radar antennas:
•
the console at least 1m (3 ft), except for SSB equipment where it must be 2m (6ft) away
•
the cables at least 500 mm (1.5 ft)
anchor Rode Specifications
Rope/Chain Anchor rodes
must have a minimum of 10 ft (3 metres) of chain. The chain must be galvanised steel, not stainless steel.
All Chain Anchor rodes
can be either galvanised steel or stainless steel.
