SRT-5000 - Input voltage or frequency problem prevents switching to bypass

    Hi,

    We've started to receive the following events on one of our SRT-5000 devices. Nothing has changed at all with the connected load or the UPS itself. There was some electrical work carried out on site a week or so ago, but I'm not sure if that could be a contributing factor. I'm hoping that someone could please take a look at a subset of the data and event logs and suggest a possible cause for the issue? I'm far from being an expert with these devices so any help would be very much appreciated.

    Power Settings:

    I've attached the data and event logs for a 24 hour period. If you need more information then please let me know.

    Edit: I also meant to ask about the effect this would have in the event of a power outage. Would the UPS have any issues switching to battery and back in the event of a power interruption\outage? Would it still charge and run normally afterwards?

    Many Thanks,


    Scott.

    Hi Scott

    This notification is just letting you know the quality of the utility power isn't good enough to be relied upon for bypass operation, there seems to be voltage or frequency fluctuations. If it was bad enough the UPS would go onto battery, so switching to battery is not a problem, however if the UPS needed to go to battery and fully disharged, and the utility power quality hadn't improved it wouldn't be able to go to battery and the output would shut off

     

    Regards

    Matt,

    Many thanks for the explanation. I appreciate you taking the time to do so.

    I'll get in touch with our facilities folk and see what they say.

    Thanks again,

    S.
