ELECTrONIC DIAGNOSTICS
Definitions SoL = Solenoid, SEN = Sensor, Lo Pr = Low Power
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 problem, contact your supplier for
further information.
SEN message: When this message is 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.
Message/Problem
1. LoC
Displayed when a button is
pressed. The AA550 will not
operate.
2. Lo Pr + a number
Displayed when the Up or Down
button is pressed. The AA550
will not operate the windlass.
3. OFF
Displayed when attempting to
use the Auto function.
Possible Solution
The safety lock is on. Hold down the
Mode button to release the safety lock
and then operate as normal.
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 18 and the
minimum voltages on page 13.
No setting has been entered for the
rode to be released so the Auto func-
tion cannot operate. Enter a length
of rode for release and the system will
operate normally. (Refer page 10
Operation Manual).
