AFFZP0BB – ACE3 – User Manual Page – 93/139
- Collect information about:
- the voltage applied across the EVP coil,
- the current in the coil,
- features of the coil.
Ask for assistance to Zapi in order to verify that the software diagnoses are in
accordance with the type of coil employed.
- If the problem is not solved, it could be necessary to replace the controller.
14) CAPACITOR CHARGE
It is related to the capacitor-charging system:
Cause
When the key is switched on, the inverter tries to charge the power capacitors
through the series of a PTC and a power resistance, checking if the capacitors
are charged within a certain timeout. If the capacitor voltage results less than
20% of the nominal battery voltage, the alarm is raised and the main contactor
is not closed.
Troubleshooting
- Check if an external load in parallel to the capacitor bank, which sinks
current from the capacitors-charging circuit, thus preventing the caps from
charging well. Check if a lamp or a dc/dc converter or an auxiliary load is
placed in parallel to the capacitor bank.
- The charging resistance or PTC may be broken. Insert a power resistance
across line-contactor power terminals; if the alarm disappears, it means that
the charging resistance is damaged.
- The charging circuit has a failure or there is a problem in the power section.
Replace the controller.
15) MOT.PHASE SH.
Cause
Short circuit between two motor phases. The number that follows the alarm
identifies where the short circuit is located:
- 36 U – V short circuit
- 37 U – W short circuit
- 38 V – W short circuit
