Error Message Possible Cause Fault Elimination
Code Error Text
65 BATTERY LOW This occurs when the battery
charge is calculated being less
than or equal to 10% of the full
charge and the BATTERY
CHECK setting is other than 0
(refer to SET OPTION menu).
Charge the battery. If charging does not help,
using a voltmeter, measure the battery volt-
age and compare the reading with the
value in the BATTERY VOLTAGE parame-
ter. If they are different, adjust the value of
the ADJUST BATTERY function.
71 EEPROM KO This is due to a HW or SW defect
of the non-volatile embedded
memory supporting the control-
ler parameters. This alarm
does not inhibit the machine
operations, but the truck will
work with the default values.
Try to execute a CLEAR EEPROM operation
(refer to CONSOLE manual). Switch the
key off and on to check the result. If the
alarm occurs permanently, it is necessary
to replace the controller. If the alarm disap-
pears, the previously stored parameters will
have been replaced by the default parame-
ters.with the temperature increases from
85

to 105

65 MOTOR
TEMPERATURE This warning occurs when the
temperature sensor is opened
(If digital) or has overtaken the
threshold of 150

C (if analog).
Check the thermal sensor inside the motor
(use the MOTOR TEMPERATURE reading
in the TESTER menu); check the sensor
ohmic value and sensor wiring. If the sen-
sor is OK, improve the air cooling of the
motor. If the warning is present when the
motor is cool, then the problem is inside the
controller.
61 THERMIC SEN-
SOR KO
The output of the controller ther-
mal sensor is out of range.
This type of fault is not related to external
components; replace the controller.
CHECK UP
NEEDED
This is just a warning to call for
the time programmed mainte-
nance
It is just enough to turn the CHECK UP DONE
option to level ON after the maintenance is
executed.
DATA
ACQUISITION
Acquisition of the current gains. The alarm ends when the acquisition is done.
