Hi All,
We've got 3 SCL500RM1UC UPS units installed, each protecting a single switch (load is around 10-15%)
The power in the area isn't the best and we occasionally have very short "blinks" in power lasting a second or 2
Today we had one of these short "blinks" in power and 2 of these units remained on battery, even though the mains power was restored, in Smartconnect the units even said there was mains power available, but they remained on battery which eventually depleted and turned the switch off - not great
What would cause this behaviour, is it a sensitivity setting or other setting we need to configure using Powerchute (support suggested this), or has anyone else had this same issue with the SCL series?
We use the larger 3kva units in our server rooms and don't have issues like this with UPS' getting stuck on battery even though there is mains power available
The electrical work is brand new and is known to be good and working
