9) EEPROM CONF.KO
Fault in the area of memory in which the special chopper configuration data is stored. If
the defect persists when the key is switched off and on again, replace the logic. Other-
wise, keep in mind that the chopper configuration has been reset to the default values
(regeneration voltage, etc.); thus it must be reprogrammed. Consult the console
manual.
10) EEPROM DATA KO
The data in the area of memory that handles the hour-metre is incorrect. This alarm
does not shut down the machine. If the alarm disappears when the machine is switched
off and on again, keep in mind that the hour-metre data has been reset to zero.
11) EEPROM OFF LINE
Fault in the nonvolatile memory that contains data relative to the area for the hour-
metre, the alarms stored and the programming parameters.
If the alarm persists when the key is switched off and on again, replace the logic.
12) CHOP. NO CONF.
An alarm similar to no.9, except that here, even though the data is correct, it does not
correspond to a hardware configuration recognised by the H2B. The considerations
are the same as for alarm 9 “EEPROM CONF.KO”.
13) WATCHDOG
The test is made in both running and standby.
It is a self-diagnosis test within the logic.
If an alarm should occur, replace the logic.
14) COIL SHORTED
There is an overcharge or a short circuit towards the positive of the battery on the
during negative contactor output.
Possible causes:
a) The coils of the contactors are in short circuit or they absorb more than 6A continue.
b) Short circuit with +batt of the cabling which cores out from the contactor connector
The alarm shows an occurred overcharge and not the fail of a chopper component.
When the external cause is removed it is possible to restart again.
15) DRIVER SHORTED
The test is carried out in standby. It checks that the during voltage of the drivers com-
manding the contactors is at a coherent value with the forecasted state.
Possible cause:
a) Logic failure
b) Drivers broken because of an overvoltage in the cabling of the negative contactors.
Replace the logic after having removed the cause.
