Article4.8.2.14S : Voltage error (V Err) on ACCL M300 3Phase
Please find the attached video herewith.
At Incoming EB power supply is healthy but ACCL not sensing it and transferred to DG. As there is no DG incoming supply ACCL shows the voltage error and not giving output.
If this error comes at DG incoming supply then need to check the DG phase selection. For example, Single-phase connected at incoming then DG phase selection on ACCL should be 1Ph.
Please check at EB all phases need to come and no loose connection would be there. Also do reset and power on/off ACCL.
If the issue not solved and everything is fine at the site. So, Need to send an ACCL replacement/ service to solve this.
