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.
How to fix String current deviation in ABB Inverter?
To address an ABB Inverter 'String current deviation' issue: 1. Read the aux code (1...8) from the Events menu -> Active faults -> String current deviations. The aux code number refers to the affected string. 2. Examine the affected string for shading. 3. Ensure the panels in the affected strings are not damaged. 4. Verify that the string monitoring configuration settings are feasible. This issue is caused by current deviation between strings.
How to resolve Extension I/O configuration failure on ABB Inverter?
If the ABB Inverter displays 'Extension I/O configuration failure', check the module type and correct the type setting in the Communications menu. The cause is that the extension I/O type setting and physical module type do not match.
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.
How to troubleshoot FBA communication error on ABB PRO-33.0-TL?
If the ABB Inverter displays 'FBA communication' error, follow these steps: 1. Make sure that the master controller can communicate. 2. Examine the adapter settings and status. Refer to the user documentation of the fieldbus interface. 3. Examine the cable connections. The cause is communication between the inverter and the fieldbus adapter or between the master controller and the fieldbus adapter is lost.
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.
What does FRT grid warning mean on ABB PRO-33.0-TL?
If the ABB Inverter displays 'FRT grid warning', no user actions are required. This is an informative warning about grid disturbance. The cause is that the trigger level for the FRT tripping curve was exceeded.
