CODE ALARM DESCRIPTION
44 THERMIC SENS KO The values indicated by the temperature sensor of theinverter are always
checked and if they are out of range there is a warning.
- Replace the logic unit.
45 SAFETY This alarm appears if the connection between the pins 5 and 11 on the JFP
connector is open.
46 CAN BUS KO Comunication failure between the logic units: traction (Master & Slave),
lifting, Mhyrio and all the cards. The alarm appears if:
- CAN H and / or CAN L signals deconnected
- there is no comunication from one logic unit.
If the problem starts from one card the system recognizes in which one:
- CAN BUS KO 0A: I/O
- CAN BUS KO 00: arm card
- CAN BUS KO 03: Master
- CAN BUS KO 04: Slave
- CAN BUS KO : Lifting logic unit (no suffix after the alarm message)
- Before replacing any logic unit it is suggested a preliminary check of the
CAN BUS connections.
Using the console, through connection numbersand selecting the
TESTER function, try to carry out a link with all the junction knots
toward the different logic units. Verify the links by, at least, one of the
signals from the field, i.e. microswitches, potentiometers. Where you
don’t reach the link, there is a line interruption.
47 WAITING Time lag fault on the CAN BUS comunication. The Lifting logic unit detects
FOR NODE wich logic unit has generated the problem
#4 The Lifting logic unit receives the informations caming from the Slave
logic unitwith 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 traction logic unit.
#3 The Lifting logic unit receives the informations caming from the Master
logic unitwith 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 traction logic unit.
#9 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.
48 AUX OUTPUT KO Failure on the contactor driver.
- Replace the lifting unit.
49 DRIVER SHORTED Failure on the contactor driver.
Check the main contactors coils and relevant wirings.
If the failure is not due to external causes, replace the lifting logic unit.
50 CONTACTOR Failure on the contactor driver.
DRIVER - Replace the lifting unit.
51 COIL SHORTED Failure on the contactor driver. Check the main contactors coils and
relevant wirings. Control that there are no short-circuits in the wiring and
that the coil resistance value is correct. If the failure is not due to external
causes replace the logic unit.
