6 AC1 INVERTER DIAGNOSTIC
The alarms are signalled by a diagnostic LED.
1 blink: logic failure ("WATCHDOG", "EEPROM KO", "LOGIC FAIL-
URE #1", "LOGIC FAILURE #2", "LOGIC FAILURE #3",
"CHECK UP NEEDED").
2 blinks: running request on start-up or error in seat sequence or dou-
ble direction request ("INCORRECT START", "HAND-
BRAKE", "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",
"PEV NOT OK", "MDI COIL SHORTED", "MDI NEG EVP",
"MDI PEV", "MDI VALVE DRIVER", "MDI DRIVER
SHORTED").
7 blinks: excessive temperature ("HIGH TEMPERATURE", "THER-
MIC SENSOR KO").
8 blinks: failure detection from can-bus ("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 param-
eters 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
occured. 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.
