DIAGNOSE FOR FAILURE 300-301-302: OC-ERRORS
1. Check if there is no short circuit on the
output of the inverter. (loose wire of motor
cable,…)
Repair the short circuit.
2. Check if there is no short circuit in the
Terminal Box of the motor. (loose wire of
the motor cable, screws or other metal
pieces who can move inside the terminal
box.)
Repair the short circuit.
Make sure the screws are sufficiently tightened.
DIAGNOSE FOR FAILURE 303-304-305 : OV-ERRORS
If there is too much regenerative energy coming from the motor (working as a generator) to the inverter, the
voltage on the capacitors will become too high and the inverter goes into OV-alarm state.
1. Check if the correct machine type is
selected in the S-submenu
If the wrong machine type is selected, enter the right
machine type
2. Check if there was a high unbalance during
extraction, which can be caused by putting
only half loads in the machine.
Put always a full load in the machine drum.
Do not put other material than textile linen (fabrics) in
the machine.
3. Check if the fault is persistent If the fault is persistent, contact the manufacturer
DIAGNOSE FOR FAILURE 306: THT-ERROR
If the output current of the inverter is abnormal high for some time, the inverter will go into THT-alarm
state.
1. Check if the power supply is sufficient high
and stable during extraction with load.
Repair the power supply.
2. Check if the drum rotates normally by hand.
(no abnormal high friction)
Repair / clean what is necessary.
3. Check if the correct machine type is selected in
the S-Menu.
If the wrong machine type is selected, enter the right
machine type.
4. Check if the correct parameters have been
loaded in the inverter.
If the correct parameters are not loaded in the inverter,
load the correct parameters.
DIAGNOSE FOR FAILURE 307: THM-ERROR
If the motor current is higher than allowed for a longer time, the inverter will active the electronic
overcurrent protection to prevent the motor from overheating and the inverter will go into THM-alarm state.
1. Check if the drum rotates normally by hand.
(no abnormal high friction)
Repair / clean what is necessary.
