Troubleshooting:
- Verify that the EB coil is connected correctly .
- Verify that the parameter POSITIVE E.B.is set in accordance with the actual
configuration . The software, in fact, depending on specific parameter value, makes
a proper diagnosis; a wrong configuration of this parameter could generate a false
fault.
- In case no failures/problems have been found, the problem is in the controller,
which has to be replaced

SHORT.
Cause:
The voltage on PEB output is at high value even if it should not. For the versions
where the smart driver is not installed (36/48V), it is possible to decide where the
positive supply for pin A27 comes from by choosing a dedicated hardware
configuration. The parameter POSITIVE E.B. has to be set in accordance with the
hardware configuration , 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 .
2 = PEB comes from PAUX . PAUX 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.

Cause:
The voltage on terminal PEB is at the high value even if the smart driver is turned
OFF.
Troubleshooting:
Verify that the parameter POSITIVE EB is set in accordance with the actual coil
positive supply . Since the software makes a proper
diagnosis depending on the parameter, a wrong setting could generate a false fault.
Check if there is a short or a low impedance path between PEB and the positive
battery terminal +B. In case no failures/problems can be found, the problem is in
the controller, which has to be replaced.
