Looking for assistance on UPS Compensating for Low Voltage alerts

[sross_apc]

Hello,

I am very new to managing a UPS, and do not know the proper ins and outs of getting them setup correctly, so please bear that in mind going forward.  I also do not have electrical experience.  A couple of months ago we installed a Smart-UPS 2200 that was at one location to another, and since then we get fairly consistent alerts throughout the day that the UPS is compensating for low voltage. One party that I work with is convinced that this is a sign of a faulty UPS, but I am not so sure of that yet.  I did not set up this UPS, but I wondered if perhaps there were some power notification settings on the UPS that weren’t set to match voltage through the outlet its coming through (I understand I could have this all wrong).  I did experiment a little and turned off ‘Green Mode’ and lowered the sensitivity but unsure if that was the right thing to do, and to be fair am still getting these alerts. I saw another topic about Compensating for Low Voltage, that might be similar to my issue, but since I am so new to this, I am unsure.  I was hoping for a little insight and direction on what I need to do to make sure settings are correct on the UPS before I deem it ‘faulty.’  Please find attached the record of events.

Provide the following logs for review: Event, Data, UPS.

Show me an image capture of all the power & quality settings on this unit. If there are other APC UPS systems on site please share the same three logs.

At a high level the system is designed to provide clean and regulated power to the connected loads.

It does this by either invoking the AVR circuit or battery only system.

The battery circuit generally speaking is managed by the power quality / sensitivity setting which varies in name from: Normal,  Reduced, Low, etc.

Some other specific models have another option to define (Power Quality) as seen in the SMX Series UPS’s.

The upper & lower output transfer limit defines when the system will go into AVR mode when the input voltage has exceeded the user defined settings as noted here.

If this is a serious Enterprise installation the facility will have a Power Quality Meter. This tool should be deployed now to monitor the same outlet the UPS is on.

The power quality meter will provide imperial data and facts about the input voltage seen here. The meter must be connected to the same outlet for a minimum of 30 days unless the data obtained is so dramatic and affirms a power quality issue.

In the interim you may consider performing the following action items and report back the results and behaviour.

Sensitivity: Set this to the widest value of low.

Transfer Voltage: Set the lower transfer voltage to the lowest value for your system.
