Voltage:
Neither the windlass nor the AA550 will operate with insuf-
ficient power. (See below). Batteries must be properly maintained and
charged and all connections and wires must be of good quality and the
correct gauge to prevent voltage drop.
To check the voltage to the
console unit: Turn the AA550 off and then press and hold the DOWN
button - the voltage will display on the LCD. During operation, if the
voltage drops below the minimum the AA550 will show
Lo Pr
and the
voltage.

Cables:
Battery and motor cables must be installed to maintain a
distance of at least 300 mm away from the sensor head. Cable speci-
fications are set out in the installation instructions and on page 18 of
this manual.
Polarity:
The AA550 is polarity sensitive. Battery polarity must be
checked before connecting the power otherwise the unit may be dam-
aged.
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.
Multiple battery bank nega-
tive terminals must be permanently connected together to become
the common negative return (ground).
Refer to the installation
instructions.
resettable Breaker Switch:
A 5 Amp switch to shut off power to the
AA550 must be installed in a position easily accessed by the operator.
