Message/Problem
Possible Solution
The aa550 is not faulty if these messages are displayed.
The diagnostics help identify problems with installation, the battery,
the solenoid and the sensor and windlass rotation. Some of the messages appear when you try to operate the AA550 but others
only appear briefly when the AA550 is turned on. Always check for the diagnostic messages by switching the AA550 off and
then on again. Use the table below to help identify a problem and provide a possible solution. If you cannot resolve the prob-
lem, contact your supplier for further information

+ a number
Displayed when the Up or
Down button is pressed. The
AA550 will not operate the
windlass.
Low power to the AA550. To check the voltage received by the AA550, turn the AA550
off, and press and hold the Down button. The voltage will display on the LCD. Check the
battery voltage output. Check wiring for loose connections. Check the cable size. If the
cable is the wrong size there may be voltage drop between the battery and the AA550. See
the cable specifications on page 2 and the minimum voltages on page 7.
SeN and Load messages: When these messages are displayed the aa550 will operate the windlass up and down manually
but the auto function will not work and the count will not be accurate.

SeN 1
Displayed briefly when the
AA550 is turned on and
when it is operated manually.
Auto does not work. No sen-
sor pulse.
1.
Load
Displayed briefly when the
AA550 is turned on and
when it is operated manually.
The Auto function does not
work.
2.
LoC
Displayed when a button is
pressed. The AA550 will
not operate.
7.
SeN 2
Displayed briefly when the
AA550 is turned on and when
it is operated manually. Auto
does not work. No sensor
pulse.
8.
SeN 3
Displayed when the AA550 is
operated manually. Auto does
not work. No sensor pulse.
The sensor wires are disconnected or the red and black sensor wires are shorted together.
AA550 will operate the windlass up and down but there will be no count displayed on the
LCD. Check sensor wiring and installation. When fixed reset the AA550 to zero twice. The
anchor must be docked. To reset to zero - press and hold the ON/OFF button. Release when
the display shows 0.0.
The load sensor wires are not connected to the motor. Use the AA550 manually and check the
load wire connections. If using an all-chain rode check that the AA550 is calibrated correctly
for all-chain. When fixed reset the AA550 to zero. The anchor must be docked. To reset to
zero - press and hold the ON/OFF button. Release when the display shows 0.0. The count will
not be correct until the problem is fixed.
The safety lock is on. Hold down the Mode button to release the safety lock and then operate
as normal.
5.
SeN
Displayed when attempting
to use the Auto function.
Use the AA550 up and down manually and check for the specific sensor error. SEN1 -
SEN5. Refer to the notes 6-10 below.
4.
OFF
Displayed when attempting
to use the Auto function.
No setting has been entered for the rode to be released so the Auto function cannot operate.
Enter a length of rode for release and the system will operate normally. (Refer page 10 Opera-
tion Manual).
The black sensor wire is shorted to ground. AA550 will operate the windlass up and down
but there will be no count displayed on the LCD. Check sensor wiring and installation.
When fixed reset the AA550 to zero twice. The anchor must be docked. To reset to zero
- press and hold the ON/OFF button. Release when the display shows 0.0.
No signal from the sensor to the AA550. Either there is no magnet, the gap between the
magnet and sensor is too big or the sensor signal is out of tune because of testing during
installation. AA550 will operate the windlass up and down but there will be no count dis-
played on the LCD. Try resetting the AA550 by running the windlass up and down for 10-15
seconds. If the message still appears check the magnet and the gap and alignment between
the magnet and sensor. Check sensor wiring and installation and check for damage to the
sensor and magnet. When fixed reset the AA550 as above. To reset manually the anchor
must be docked and the AA550 reset to zero twice. To reset to zero - press and hold the ON/
OFF button. Release when the display shows 0.0.
