ERROR ERROR TEXT POSSIBLE CAUSE FAULT CLEARANCE
6 SERIAL ERR #1 Main uC and Slave uC communicate via
a local serial interface. This alarm
occurs when the slave uC does not
receive the communication from the
main uC through the serial interface.
Replace the controller.
13 EEPROM KO This occurs if a test to write and read
one location in EEPROM fails. The SW
expects to read the written value. It can
also occur when the hour counter gives
different values between the three
redundant location in which it is
recorded. It also occurs when the busy
bit of the EEPROM does not rise within
12 msec.
Replace the controller.
16 LOGIC FAILUREE #4 This alarm occurs in the rest state if the
output of the voltage amplifier of the
phase Vw-Vv have a drift larger than
±0.25 V.
Replace the controller.
17 LOGIC FAILURE #3 This alarm occurs in the rest state if the
output of the voltage amplifier of phase
Vu-Vw have a drift larger than ±0.25 V.
Replace the controller.
18 LOGIC FAILURE #2 This alarm occurs when the real voltage
between phases X and V of the motor
is different from the desired.
Replace the controller.
19 LOGIC FAILURE #1 This alarm occurs when the real voltage
between phases W and U of the motor
is different from the desired.
Replace the controller.
32 VMN NOT OK This alarm occurs in the initial rest state
after key on if the output of the motor
voltage amplifiers are not in the win-
dow from 2.2 to 2.8 Vdc.
Replace the controller.
48 MAIN CONT. OPEN This alarm occurs only when the setting
CAN BUS is PRESENT. Then the
EPS-AC0 waits for a via CAN informa-
tion that the traction controller has
closed the main contactor. If this infor-
mation lacks more than 1.5 secs, this
alarm occurs.
Find, on the traction controller, the rea-
son for keeping the main contactor
open.
53 STBY I HIGH This alarm occurs two ways:
1.
In the initial rest state after key on, if
the outputs of the current amplifiers
are not comprised in the window 2.2
to 2.8 Vdc.
2. After the initial diagnosis this alarm
occurs when the output of the cur-
rent amplifiers at rest have a drift
larger than ±0.15 V.
Replace the controller.
