ACQUIRING A.S.
(MDI/LED code = 2)
Cause:
Controller is acquiring data from the absolute feedback sensor.
Troubleshooting:
The alarm ends when the acquisition is done.
ACQUIRE END
(MDI/LED code = 2)
Cause:
Absolute feedback sensor acquired.
ANALOG INPUT
(MDI/LED code = 96)
Cause
This alarm occurs when the A/D conversion of the analog inputs returns
frozen values, on all the converted signals, for more than 400 ms. The goal of
this diagnosis is to detect a failure in the A/D converter or a problem in the
code flow that skips the refresh of the analog signal conversion.
Troubleshooting
If the problem occurs permanently it is necessary to replace the logic board.
AUX BATT. SHORT.
(MDI/LED code = 27)
Cause:
The voltage on PEB output (pin
A2
) is at high value even if it should not.
For the versions where the smart driver is not installed (36/48V and 80V), it is
possible to decide where the positive supply for pin
A2
comes from by
choosing a dedicated hardware configuration. The parameter POSITIVE E.B.
has to be set in accordance with the hardware configuration (see paragraph
8.2.5), because the software makes a proper diagnosis depending on the
parameter; a wrong setting could generate a false fault. The available
choices are:
- 0 = PEB is managed by the smart driver (available for 24V version
only).
- 1 = PEB comes from the TILLER input (
A1
).
- 2 = PEB comes from PEV (
A3
). PEV must be connected to terminal
+B of the controller. This is the default configuration for 36/48V and
80V version.
This alarm can only appear if POSITIVE E.B. is set as 1 TILLER/SEAT.
Troubleshooting:
-
Verify that the parameter POSITIVE E.B. is set in accordance with the
actual coil positive supply (see paragraph 8.2.5).
-
In case no failures/problems have been found, the problem is in the
controller, which has to be replaced.
BATTERY LOW
(MDI/LED code = 0)
Cause:
Parameter BATTERY CHECK is other than 0 (SET OPTION list, paragraph
8.2.2) and battery charge is evaluated to be lower than BATT.LOW
TRESHLD (ADJUSTMENTS list, paragraph 8.2.3).
Troubleshooting:
-
Check the battery charge and charge it if necessary.
