Why is my LSIS Inverter overheating?
Your LSIS Inverter may be overheating due to several reasons. First, check the cooling system for any obstructions in the air inlet, outlet, or vent. The cooling fan may also need replacement if it has been operating for an extended period. Finally, ensure the ambient temperature is below 50?. These steps should help resolve the overheating issue.
What to do if LSIS Inverter shows E-Thermal error?
If your LSIS Inverter displays an E-Thermal error, it could be due to several reasons: * The motor might be overheated, in which case you should reduce the load or operation frequency. * If the inverter load is greater than the rated capacity, replace the inverter with a model that has increased capacity. * If the set value for electronic thermal protection is too low, set an appropriate electronic thermal level. * If the inverter has been operated at low speed for an extended duration, replace the motor with a model that supplies extra power to the cooling fan.
What causes LSIS Inverter to display Inverter OLT error?
The 'Inverter OLT' error on your LSIS Inverter typically indicates that the load exceeds the rated motor capacity. To resolve this, replace the motor and inverter with models that have increased capacity. Alternatively, the torque boost level might be set too high; try reducing it.
What to do if LSIS Inverter shows FAN Lock error?
If your LSIS Inverter displays a FAN Lock error, it's likely due to either a foreign object obstructing the fan’s air vent or the cooling fan needing replacement. First, remove any foreign objects from the air inlet or outlet. If the issue persists, replace the cooling fan.
What to do if LSIS Inverter has Input Phase Open error?
If your LSIS Inverter is showing an Input Phase Open error, there are a few things you can check. It could be due to a connection fault in the magnetic contactor on the input side, so check that first. Also, inspect the input wiring for any faults. If neither of those is the issue, the DC link capacitor might need replacing.
How to troubleshoot low voltage on LSIS Inverter?
Low voltage on your LSIS Inverter can stem from a few causes. First, ensure that the input voltage is adequate. If the input voltage is sufficient, check whether a load exceeding the power capacity is connected to the system. Also, inspect the magnetic contactor connected to the power source for any faulty connections and replace it if necessary.
What causes LSIS Inverter to display Output Phase Open error?
An Output Phase Open error on your LSIS Inverter can be caused by a connection fault in the magnetic contactor on the output side, or faulty output wiring. Check the magnetic contactor and the output wiring to resolve the issue.
What to do if LSIS Inverter shows IP54 FAN Trip error?
If your LSIS Inverter is showing an IP54 FAN Trip error, it could be due to the fan connector not being connected, so ensure it is properly connected. If it is already connected, the fan connector may need to be replaced.
Why does LSIS Inverter show NTC Open error?
The NTC Open error on your LSIS Inverter indicates that the ambient temperature is too low. Ensure the ambient temperature is above -10?.
Why is the IP address of my LSIS Control Unit communication module randomly changing?
If the IP address of your LSIS Control Unit communication module is randomly changing, it might be due to the PLC settings overriding it. Verify the PLC configuration software to check if IP changes by the PLC are permitted. If you prefer the communication module's IP to remain constant, configure the PLC software to utilize the IP address defined within the communication module itself.
