10 AC-2 FLASH 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,

double direction request or encoder problem

("INCORRECT START", "HANDBRAKE", "FORW +

BACK", "ENCODER ERROR").

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", "PEDAL FAILURE").

5 blinks: failure of current sensor ("STBY I HIGH", "DATA

ACQUISITION").

6 blinks: failure of contactor driver ("COIL SHORTED",

“DRIVER SHORTED", "CONTACTOR DRIVER", "AUX

OUTPUT KO", "CONTACTOR OPEN", "CONTACTOR

CLOSED").

7 blinks: excessive temperature ("HIGH TEMPERATURE",

"MOTOR TEMPERATURE", "THERMIC SENSOR

KO", "MOT. TH. SENSOR KO").

8 blinks: failure of can-bus or problem in the SAFETY circuit

("CAN-BUS KO", "SAFETY", "SAFETY KO").

long blink: discharge battery or wrong battery voltage ("LOW

BATTERY", "WRONG SET BATT.").

no blink: problem in a remote module ("WAITING FOR NODE").

10.1 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 occurred. 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.
