Neither the windlass nor the AA550 will operate with insufficient 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
If the windlass is already operating, this is the minimum voltage
required to continue operating.

Refer to the Operation Manual Part 2.
Windlasses Using Rope/Chain Rode -
Select the windlass from the Preprogrammed Windlass List and enter this at
Calibration Item 5.
Windlasses Using all-Chain Rode
- Use the Custom Setting at Calibration Item 5 and enter the chainwheel circumference at
Item 6. The circumferences for many windlasses are set out on the Preprogrammed Windlass List.
Before installation can be considered complete, the AA550 must be calibrated to comply with the boat’s windlass and rode and
then tested to ensure it is working correctly.
CONNeCTIONS TO THe WINdLaSS MOTOR
Windlasses Using Rope/Chain Rode:
Short Circuit Protection is required on the load sensor wires (1 x brown/1 x white)
that connect direct to the motor terminals. The connectors supplied have a 1000 Ohm resister prefitted. If you do not
use these connectors a 100ma fuse must be fitted.
The joins should be soldered or crimped, and sealed. If the load sensor
wires are not connected properly the AA550 will not count rope/chain accurately and the automatic function will not work.
A
Load
warning message will display on the LCD.
Note: The brown wire must connect to the UP terminal.
Check the
windlass rotation before connecting this wire.
Windlasses Using all-Chain Rode:
The load sensor wires are not required for windlasses using all-chain rode. They can be
left unconnected. If you choose to connect these wires then the instructions for windlasses using rope/chain rode must be
followed.
All main power conductors and terminations are to be installed according to the windlass manufacturer’s specifications. Seal
terminals against moisture by spraying with CRC [3013] Soft Seal or CRC [2043] Plasticoat 70.
ReSeT dISPLaY TO ZeRO
Turn the AA550 on. Clear the safety lock if necessary. Press and hold the ON/OFF button. A rapid beeping will be heard.
Release the ON/OFF button when the display shows 0.0.
ReSeT FaCTORY deFaULT SeTTINgS
This setting should only be used if the aa550 settings have been corrupted. Using this setting will remove all
your calibration settings.
To apply the factory reset: Turn the AA550 off. Hold down the MODE and UP buttons together. While holding these
buttons press and release the ON/OFF button. When the LCD display reads LoAd release the MODE and UP buttons. The
unit will turn itself off and the factory default settings will be reset.
Now re-enter the calibration settings for your unit. Refer Part 2 of the Operation Manual.
