89 PUMP VACC
NOT OK
The minimum of the lift potentiom-
eter is not correctly set.
It is suggested to repeat a “PROGRAM VACC”
procedure.
67 SENS. MOT.
TEMP. KO
• The motor temperature sensor is
not correctly connected to A22.
• The motor temperature sensor is
damaged.
- Check the correct connection of the motor
temperature sensor.
- If the current sensor is correctly connected,
replace it.
- If the problem persist, replace the controller.
Error Message Possible Cause Fault Elimination
Code Error Text
6 SERIAL ERR #1 Main uC and slave uC communi-
cate via a local serial interface.
This alarm occurs when the
slave uC does not receive the
communication from the main
uC through this serial interface.
It is necessary to replace the controller.
13 EEPROM KO It occurs if a test to write and read
one location in EEPROM fails.
The SW expects to read the
written value.
It also occurs when the hour
meter gives different values
between the three redundant
locations in which it is
recorded.
It also occurs when the busy bit of
the EEPROM does not rise
within 12 msec.
It is necessary to replace the controller.
16 LOGIC FAILURE
#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.
It is necessary to replace the controller
17 LOGIC FAILURE
#3
This alarm occurs in the rest state
if the output of the voltage
amplifier of the phase Vu-Vw
have a drift larger than
±0.25 V.
It is necessary to replace the controller
18 LOGIC FAILURE
#2
This alarm occurs when the real
voltage between phases W
and V of the motor is different
from the desired voltage.
It is necessary to replace the controller
