How to reset Maintenance Bypass for Smart UPS VT

[Anonymous user]

Is there a way to reset a Smart UPS that has gone into the Maintenance Bypass mode? The unit has dropped the load and every attempt to turn off the Maintenaance Bypass mode through the Control panel has failed.

hi

If the unit is in Maintenance Bypass, then either Q7 (mechanical bypass switch) or Q3 (if the unit has an installed maintenance bypass panel) are engaged and need to be physically manipulated to the "open" or "off" position. If the unit is in internal Static Bypass and cannot be commanded out of bypass, there may be a fault on the UPS that is keeping the unit from returning to normal operation.

-is the Fault LED lighted?
-from the powerview display, go to the root menu and select "Diags" then "Fault and Diagnostics"; what is displayed?
-if the above doe not apply, from the powerview display go to the root menu and select "Control" then "UPS out of bypass" and "YES" to confirm; what does the UPS state?

We recommend you phone in the issue unless the switch is really on/ closed and then all that is needed is to operate the MBP lever down.

I have looked at the attachment and it is the internal Static Bypass that cannot be commanded out of bypass. I think there is a fault that is keeping the unit from returning to normal operation.

I have contacted the support and someone will be coming over to troubleshoot the unit.

Thanks for your time.

Regards.
