Troubleshooting:
If the EVP TYPE parameter is set to ANALOG (See paragraph 8.1.1), please
acquire again the values of MIN LOWER and MAX LOWER.
If the controller is in configuration COMBI and lifting is proportional, please
acquire again also the values of MIN LIFT and MAX LIFT.

SMART
DRIVER KO
Cause:
There is a hardware problem in the smart driver circuit . The driver is set to
be ON but the output voltage does not increase
Troubleshooting:
- Verify that the EB coil is connected correctly between pin A2 and pin A4.
- Verify that the parameter POSITIVE E.B.is set in accordance with the
actual configuration (see paragraph 8.2.5). 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

AUX BATT.
SHORT.
Cause:
The voltage on pin A2 is at high value even if it shouldn
’
t. For the version
where the Smart Driver is not installed (36/48V and 80V) it is possible to
decide where the positive supply for pin A2 is taken from by dedicated
hardware configuration:
- pin A3 (PAUX)
- pin A1 (TILLER)
- externally from other module (i.e. EPS)
The parameter
“
Positive EB
”
has to be set in accordance with hardware
configuration :
Troubleshooting:
- Verify that the parameters
“
Positive EB
”
is set in accordance with the
actual coil positive supply . The software, in fact,depending by specific
parameter value, makes a proper diagnosis; a wrong configuration of the
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.

POS. EB.
SHORTED
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.
