Unusual "Bypass not in range" alert

[Anonymous user]

Firmware is 3.5.8. UPS model : 3kva Smart UPS

Customer set Bypass Upper Voltage at 265V and when the incoming voltage is 255V, the output voltage is set to 240V they received a ‘UPS: Bypass not in range; high voltage’ alert.
Any ideas why this would occur as it appears that with the Upper Voltage set to 265 an input of 255 should not generate an alert?
I asked for and got input voltage data from a little before 12/10/2009 21:15:10 to a little after 12/11/2009 04:00:29
I can send this if required

The UPS can continue to operate with the input voltage it is getting. However the message you are getting is probably a result of the bypass voltage being to much of a difference from the UPS output to make an uninterupted transfer from UPS to Bypass.

Is this an international model in an international config? I noticed the output frequency is 50hz rather than 60. Do you have the exact model number of the UPS?

Also, in regard to the message, is that the exact error - it specified high voltage as the cause? Was this an email alert or reported in the NMC web interface?

Finally, we recently released v3.7.1 for the card's firmware, and an update couldn't hurt.
