ERROR SOURCE
CAUSE
REMEDY
a- main board failure
a- replace the main board MECE00265 ;if control panel
release is < 1.26, replace the control panel MEQE00050 too
a- machine worked too much in a ramp
a- wait
≈
30' that the traction wheel temperature go down
b- the motor current consumption
b- if current is > 18A replace the tration motor RTRT00250
c- the motor thermal sensor
c- if at ambient temperature is open, replace it, METK00026
a- machine worked too much in a ramp
a- wait
≈
30' that the main board temperature go down
b- the motor current consumption
b- if current is > 18A replace the tration motor RTRT00250
c- replace the main card MECE00265 and the control panel
MEQE00050
a- pedal in pushed before key turning ON
a- release the pedal
a- the plug under the pedal bad connected

b- replace the potentiometer (see service bulletin 20060047)
a- machine worked too much at high pressure
a- wait
≈
30' that the main board temperature go down
b- the working program is to heavy for the floor
b- pass from P3 to P2 or P1 ( if already P1 use the
programming instruction to check the pressure value setted )
c- electronics faulty
