6 AC INVERTER DIAGNOSTIC - TRACTION CONFIGURATION

The alarms are signalled by a diagnostic LED.

1 blink:

logic failure ("WATCHDOG", "EEPROM KO", "LOGIC FAILURE #1",

"LOGIC FAILURE #2", "LOGIC FAILURE #3", "CHECK UP NEEDED").

2 blinks:

running request on start-up or error in seat sequence or double direction

request ("INCORRECT START", "HANDBRAKE", "FORW + BACK").

3 blinks:

phase voltage or capacitor charge failure

("CAPACITOR CHARGE", "VMN LOW", "VMN HIGH").

4 blinks:

failure in accelerator ("VACC NOT OK", "PEDAL WIRE KO").

5 blinks:

failure of current sensor

("STBY I HIGH").

6 blinks:

failure of contactor driver

("COIL SHORTED", "DRIVER SHORTED", "CONTACTOR DRIVER", "AUX OUTPUT
KO", "CONTACTOR OPEN").

7 blinks:

excessive temperature ("HIGH TEMPERATURE", "MOTOR TEMPERA-

TURE", "THERMIC SENSOR KO").

8 blinks:

failure detection from can-bus ("WAITING PUMP", "CAN-BUS KO").

long blink: discharge battery ("LOW BATTERY")

6.1 ANALYSIS OF ALARMS DISPLAYED ON CONSOLE

1. WATCH DOG

The test is made in both running and standby. It is a self-diagnosing test within the
logic. If an alarm should occur, replace the logic.

2. EEPROM KO

Fault in the area of memory in which the adjustment parameters are stored;  this alarm
inhibits machine operation. If the defect persists when the key is switched OFF  and
ON again, replace the logic. If the alarm disappears, remember that the parameters
stored previously have been cancelled and replaced by the default values.

3. LOGIC FAILURE #1

This alarm signals that an undervoltage / overvoltage protection operation has oc-
curred. Two possible reasons:
a. A real undervoltage / overvoltage situation happened.
b. Fault in the hardware section of the logic board which manages the overvoltage

protection. Replace the logic card.

4. LOGIC FAILURE #2

Fault in the hardware section of the logic board which manages the phase' s voltage
feedback. Replace the logic board.

5. LOGIC FAILURE #3

Fault in the hardware section of the logic board which manages the hardware current
