CODE ALARM
DESCRIPTION
52
VACC NOT OK
Failure on the lifting potentiometer signal at rest. The alarm points out
that the voltage value detected on the lifting potentiometer is 1Volt
higher than the least value programmed with the Vacc function. Check:
- The tlifting potentiometer (it could be damaged or not correctly
calibrated)
- The lifting potentiometer wiring.
- Carry out the Vacc setting again.
53
INCORRECT START Incorrect sequence from the start. Check:
- Control valve microswitcheis and relevant wires.
If the failure is not due to external causes replace the traction logic unit.
54
PEDAL WIRE KO
Failure on the lifting potentiometer signal at rest. This alarm appears
when there is an interruption on the potentiometer positive (PPOT) or the
negative (NPOT). Check:
- lifting potentiometer (could be damaged)
- lifting potentiometer wiring.
55
WRONG BATTERY
When the key is turned ON, the controller checks the battery voltage and
compares it with the “SET BATTERY” parameter setting. If the actual value
is 20% higher or lower than the nominal value, there is a fault. Replace the
battery with a correct one.
56
REMOTE INPUT
Incorrect starting procedure.
57
WAITING
The Lifting logic unit receives the informations caming from the
Mhyrio logic unit with a time lag fault.
The fault can be caused by
- interference on the CAN-BUS. Check the CAN-BUS comunication.
- false contact. Check the connections of CAN H and CAN L wires.
- broken logic. Replace the Mhyrio logic unit.
58
I= 0 EVER
Failure on the current sensor. Replace the lifting unit.
59
Not used.
4A
Not used
4C
BATTERY_LOW
Discharged battery. If the “battery check” option is ON, a battery discharge
algorithm is carried out. When the charge level is 10% , this alarm is
signalled and the current is reduced to the half of the programmed level.
5A
CHOPPER
The lifting unit has an erroneous configuration. Using the programming
NOT CONF.
console it is possible to set the unitcorrectly according to the truck
configuration:
a. (joystick ON) control valve version
b. (joystick OFF) fingertip - joystick version.
4E
Not used.
5C
GAIN ACQUISITION This warning communicates that the logic is in phase of input acquisition. In
this phase the logic doesn't start.
5E
Not used.
MHYRIO UNIT
A1
EEPROM KO
Fault in the area of memory in which the adjustment parameters are stored;
this alarm inhibits the truck operation, but the controller will use default
parameters. If the defect persists when the key is switched OFF and ON
again, replace the logic. If the alarm disappears, remember that the
parameters previously stored have been deleted and replaced by
the default values.
A2
DRIVER SHORTED
The transistor that controls the lifting and lowering valvespositive supply is
closed when it should be open. Replace the logic unit.
