07 VMN HIGH
Condition for error detection
Failure in the VMN test.
This test starts when the ignition key is turned ON and there is no current consumption (machine
stationary) The alarm appears if the power circuit connections are open; check the connection of the 3
power cables from the logic unit to the traction motor and the cables condition.
To determine the cause of the fault, proceed by running one of the tests described below:
TEST 1
• Operate the parking brake and switch off the machine
• Open the compartment and disconnect the battery
• Check the power cables on the motor are tight
• Check the power cables on the logic unit are tight
• Check the continuity values between the following points on the control unit using a tester:
Self-diagnostic
Connect the drive logic unit to the pump motor and check whether the display shows the alarm code
"07".
YES: replace the logic unit
If alarm “37“ appears check the motor state (see paragraph INSULATION CONTROL PROCEDURE and
MOTOR WINDING CONTROL PROCEDURE)
Values on the control with connected motor Values on the control with disconnected motor
Red cap Black cap Resistance Red cap Black cap Resistance
If very different values are measured compared to
those referred to in the above table,
disconnect all the power cables from the logic unit and
repeat the measurements
If an open circuit is detected, replace the logic
unit
