7 AC-2 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").
7.1 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.
