The problem in the "Surge Guard" would appear to be more then just a display issue because the processing unit must also be detecting the higher voltages and is making the decision that something is wrong and shuting down the feed.
So, from the original post, the unbalanced loads are being detected, albeit at appartently erroneous voltage levels. So, the unit is not completely out to lunch, just half way. :)
I don't know anything about this but: Would it be the erroneous voltage levels on the digital read-out telling the automatic transfer switch to shut down then? So maybe just need to replace a couple parts (digital read-out and ATS)??
Actually, it may be even easier then that, it may just be a minor calibration issue, it is over reading by 4% but otherwise doing the right things. The root problem would appear to be with the calibration of the Analog to Digital (AKA A/D) converter. This function may have a calibration adjustment pot. The manufacturere would help your Electrician through the procedure if this were the case.
