How to troubleshoot a FAN Trip error on an LSIS Inverter?
If your LSIS Inverter displays a FAN Trip error, there may be a foreign object in the inverter vent where the fan is located, so remove any obstructions from the air inlet or outlet. The cooling fan might also need to be replaced, so replace the cooling fan.
What causes Over Voltage in LSIS Inverter and how to fix it?
An Over Voltage error in your LSIS Inverter can stem from several factors. The deceleration time might be too short for the load inertia, so try increasing it. A generative load at the inverter output could be the cause, suggesting the use of a braking unit. Also, verify that the input voltage isn't exceeding the specified value. Additionally, ensure the electronic thermal protection level is appropriately set and if the inverter has been operating at a low speed for a long period, consider replacing the motor with one that provides extra power to the cooling fan.
Why does my LSIS Inverter display Over Load?
Your LSIS Inverter might be showing an Over Load error because the load is exceeding the motor's rated capacity. Ensure that both the motor and inverter have appropriate capacity ratings. Alternatively, the set value for the overload trip level (PRT-21) might be too low; in that case, increase the set value.
What to do if LSIS SV-IS7 Inverter shows Low Voltage /Low Voltage2?
If your LSIS Inverter is showing a Low Voltage /Low Voltage2 error, it could be due to a few reasons. First, check if the input voltage is below the specified value. Another cause might be a load connected to the system that exceeds the power capacity, such as a welder or direct motor connection; in this case, increase the power capacity. Finally, the magnetic contactor connected to the power source might have a faulty connection, requiring its replacement.
How to troubleshoot an E-Thermal error on an LSIS SV-IS7?
An E-Thermal error on your LSIS Inverter indicates that the motor has overheated. Try reducing the load or operation frequency. It could also mean that the inverter load is greater than its rated capacity, in which case you should replace the inverter with a model that has increased capacity.
How to fix Over Heat error on LSIS Inverter?
If your LSIS Inverter is showing an Over Heat error, it could be due to a few reasons: * There may be a problem with the cooling system, so check for any obstructions blocking the air inlet, outlet, or vent. * The inverter cooling fan might have been operating for an extended period, requiring its replacement. * The ambient temperature could be too high; ensure it remains below 50?.
What does No Motor Trip mean on my LSIS SV-IS7 Inverter?
If your LSIS Inverter displays a No Motor Trip error, the motor might not be connected to the inverter output, so check the wiring connections. It could also mean that the current level for trip detection is not set properly, so check the values of both BAS-13 (Rated current) and PRT-32 (No Motor Level).
What does NTC Open mean on my LSIS Inverter?
If your LSIS Inverter displays an NTC Open error, the ambient temperature might be too low, so keep the ambient temperature above 10?. It could also mean there is a fault with the internal temperature sensor. In this case, contact the retailer or LSIS Customer Support.
What to do if LSIS SV-IS7 displays Under Load?
If your LSIS Inverter displays an Under Load error, it could mean there is a motor-load connection problem, so replace the motor and inverter with lower capacity models. It could also mean that the set value for the underload level (PRT-29 and PRT-30) is less than the system’s minimum load, so increase the set value for the underload level.
What does In Phase Open mean on my LSIS SV-IS7?
If your LSIS Inverter displays an In Phase Open error, it indicates a connection fault with the magnetic contactor on the input side. Check the magnetic contactor. It could also mean the input wiring is faulty, so check the input wiring. Also, the DC link capacitor might need replacement. In this case, contact the retailer or LSIS Customer Support.
