how do you change the high input voltage threshold?

[Anonymous user]

have a site where input voltage goes up to 127V. get frequent alerts stating "UPS: compensating for high input voltage". would like to change the threshold to 128V before alerting. How do i make that change?

management card: UPS Network Management Card 2
UPS: Smart-UPS 2200
firmware: ID18UPS 08.8

Hi Nathan

You can change the low and high transfer points to control at what input voltage the UPS will transfer to battery.

The alert you are getting appears to be the UPS notifying you that it is using the AVR to trim the voltage down to an acceptable level. This isn't something that can be altered.

However  you can remove it from the list of events on your NMC log and if you are receiving it in emails going to 

Configuration / Notification / Event Actions / By Event / Input Line Status
