How to resolve Extension AI parameterization error on ABB Inverter?
If the ABB Inverter displays 'Extension AI parameterization' error: 1. Check the correct input signal type. 2. Set the slide switch accordingly. 3. Adjust the software settings to match the positions of the slide switches in the Communications menu. The cause is that the slide switch (current/voltage input) setting on the module does not match the software settings.
What to do if ABB PRO-33.0-TL shows Ground current error?
If the ABB Inverter shows a 'Ground current' fault, follow these steps: 1. Power down the inverter. 2. Ensure no people, animals, or objects are in danger or contact with the electrical parts of the PV system. 3. Visually inspect the PV system's cabling for faults or burn marks. 4. If the system appears normal, restart the inverter. If the fault persists, immediately isolate the inverter from all power sources and request a service visit from your system supplier. This fault may indicate a dangerous AC or DC side isolation fault and contact to ground, or leakage current to ground because of human, animal or other contact between electrical parts and ground or because of water or high humidity.
What to do if ABB PRO-33.0-TL Inverter displays Isolation fault?
If the ABB Inverter displays 'Isolation' fault: 1. Power down the inverter. 2. Make sure that no people, animals or other objects are in danger or in contact with the electrical parts of the PV system. 3. Visually examine the cabling of the PV system for faults or burn marks. 4. If the system looks normal, restart the inverter. If the same fault occurs again, power down the inverter and contact your system supplier. The cause is low impedance between DC+ or DC- bus of the inverter and the ground.
What causes Rating ID mismatch on ABB Inverter?
Restart the ABB Inverter. The cause is that after a firmware update, the hardware of the inverter does not match the information stored in the memory.
What does Reverse string current mean on ABB PRO-33.0-TL Inverter?
If the ABB Inverter displays a 'Reverse string current' fault: Standard/-S model: Read the aux code from the Events menu -> Active faults. Aux code (255) refers to reverse current in the DC input terminals. Power down the inverter and contact authorized service personnel to make sure that your installation does not have short circuits and connection errors. -SX model: Read the aux code from the Events menu -> Active faults. The aux code refers to affected DC input terminal on the bottom of the inverter. Read the string current values from the Events menu -> String monitoring -> String current. If there are no negative values, reset the fault. If a value shows negative current, the fault is still active: power down the inverter. Make sure that all of the DC connectors are in their correct p...
What to do if ABB Inverter shows Internal fan run time error?
If the ABB Inverter displays 'Internal fan run time', contact authorized service personnel to replace the internal fan. The cause is that the internal fan has reached the end of its life.
What causes Backup/restore timeout on ABB PRO-33.0-TL?
If the ABB Inverter displays 'Backup/restore timeout', examine the communication, reset the fault and do the operation again. The cause is a temporary communication error between the control or PC tool and the inverter.
How to fix Ext. I/O communication loss on ABB PRO-33.0-TL?
If the ABB Inverter displays 'Ext. I/O communication loss': 1. Power down the inverter. 2. Make sure that the module is correctly installed in Slot 1. 3. Restart the inverter. If the same fault occurs again, the module may be broken. The cause is that the inverter cannot communicate with the extension I/O module.
What to do if ABB PRO-33.0-TL shows Licensing fault?
Contact ABB to replace the unit. The cause is that a license is required for the inverter to operate and the license is missing.
What causes Input overcurrent on ABB PRO-33.0-TL?
If the ABB Inverter displays 'Input overcurrent', restart the inverter. When the inverter returns to normal operation, monitor the inverter for a few days. The cause is that the inverter was not able to limit the input current to the maximum value during a sudden change in operating conditions.
