Supply voltage for the KRONE Machine Controller (KMC) at connection UE
Possible cause
Remedy
FMI 3: An overvoltage or a short circuit to the supply voltage has occurred.
The cabling is faulty.
Check the cabling for damage,
.
One or several sensors/actu-
ators connected to the voltage
group are defective.
An overview of the position of the sensors, actuators and
control units is provided in the circuit diagram,
Check the sensor and cabling for damage,
The control unit KMC is de-
fective.
Replace the control unit KMC.
Note the error number with the FMI and contact the KRONE
service partner.
