4. Check if the fuses are still functional If the fuses are blown up : replace the fuses
5. Check if the safety contactor is activated If the safety contactor is broken : replace the contactor
6. Check if the connectors on both sides of the
communication cable are still connected
Connect the connectors on the electronic board and
the inverter.
7. Check if the wiring is still continue Repair the wiring
8. Check if the output relays that activates the
safety inverter contactor is functional
If the relay is broken, replace the electronic board
9. Check if the output relays that activates the
safety inverter contactor is functional
If the relay is not broken, but doesn’t receive a signal
from the electronic board, replace the electronic board
FAILURE 28: THT TIME OUT
Fault 28 occurs when the software can not handle the THT fault of the frequency inverter.
This fault is a specific fault of the frequency inverter caused by an overcurrent.
DIAGNOSE:
1. Check if the correct machine type is
selected in the Configuration Menu.
If the wrong machine type is selected, enter the right
machine type
2. Check if the correct inverter parameters
have been implemented.
Load the correct Inverter parameters.
3. Check if the fault is persistent If the fault is persistent, contact the manufacturer
FAILURE 29: OV3 TIME OUT
Fault 29 occurs when the software can not handle the OV3 fault of the frequency inverter. This fault is a
specific fault of the frequency inverter caused by an overvoltage during deceleration.
DIAGNOSE:
1. Check if the correct machine type is
selected in the Configuration menu.
If the wrong machine type is selected, enter the right
machine type
2. Check if the correct inverter parameters
have been implemented.
Load the correct Inverter parameters.
3. 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.
4. Check if the fault is persistant If the fault is persistent, contact the manufacturer
FAILURE 30: ALARM FREQUENCY INVERTER
Fault 30 occurs when the frequency inverter goes into alarm. Except for the THT and the OV3 fault where the
timer software will reset the inverter automatically (only 1x). The active process will be interrupted
immediately.
DIAGNOSE:
1. Check if the correct machine type is
selected in the Configuration Menu.
If the wrong machine type is selected, enter the right
machine type
2. Check if the correct inverter parameters
have been implemented.
Load the correct Inverter parameters.
3. Check the frequency inverter error list to
know what happened.(See manual inverter)
If the fault is persistent, contact the manufacturer
FAILURE 31: INITIALISATION FAULT INVERTER
While the parameter set of the frequency inverter is written to the EEPROM memory of the inverter and a
fault occurs during this action then Fault 31 will be displayed.
