4-42
3E POWER MOS SHORTED
Condition for error detection
The alarm signals a power circuit failure.
Verify the correct connection of the motor to the logic:
• One or more motor phases could be disconnected
• Power cables connection
• Truck insulation and motor state see paragraph INSULATION CONTROL PROCEDURE and MOTOR
WINDING CONTROL PROCEDURE)
• Continuity values obtained directly on the control, with disconnected power cables:
Replace the logic unit.
3F FLASH CHECKSUM
Condition for error detection
Control internal error.
• - Restore the default parameters using the RESET logic unit function
• If the error persists when the machine is switched back on, install the last version of the software using
the programmer.
• If the defect persist when the key is switched OFF and ON again, replace the logic unit.
4A SOFTWARE ERROR -
Condition for error detection
Error in the memory data where the flowing parameters are loaded.
Make a logic unit RESET to re-load the default parameters.
• If the error persists when the machine is switched back on, install the last version of the software using
the programmer.
• If the problem presists replace the logic unit.
If an open circuit is detected, replace the logic unit
