Output Voltage is out of range

[slepere1]

I'm seeing this in my logs, what does it mean? input voltage is 56V. am I too hot?

Is that on the MINI? What version of firmware? Newest firmware raised the voltage threshold.

Yea, my "guess" is that sheet of paper that warns people to upgrade firmware first went straight into the trash?

Also for shits and giggles please explain your setup so we can maybe help you before you run into another problem.

How are you powering the WS-6-MIN?

Describe your tower and or setup here.

Where are you getting AC power from.

Maybe a couple pictures.

this is a brand new ws-12-250-dc switch - firmware was upgraded to the newest at the time it was opened - maybe two weeks ago. 1.4.1, so you guessed wrong on that. this switch was the replacement for the one that is rebooting (other ticket).

this is a building roof top. power is clean house power. 120v AC. We are Using a meanwell Ad-155C dc power supply. its output is 56v DC & 4x 150ah batteries for a UPS.

I did guess wrong, happens to all of us sometimes.

Please post up a device Status Tab after you upgrade.

okay - i updated to 1.4.2 today. seems as this error has gone away for now.

im still seeing this error in the logs after firmware update to 1.4.2
Any suggestions?

So other than the error in the log what else is happening or is it just that annoying error? (which needs addressed to figure out why it is happening)

In reality 50V is what we are aiming for on the output but anywhere from 48V to 53V is perfectly OK , 56V would be borderline to high.
This is the second switch you put here that did this right? If so there has to be something environmental causing it but what?

If this is not the second unit then it could be a bad trim resistor on the DC2DC power supply or a bad voltage sensor on the DC2DC or switch board. The switchboard has a voltage sensors but I am not sure if we rely on the DC2DC power supply sensor for that reading?

OK what is powering this device? On your other post you are powering a WS-12-250-DC with a power supply which is not the intended application of the WS-12-250-DC.

If you are going to provide a modified SINE wave power supply to provide conditioned power you want the WS-12-DC not the WS-12-250-DC
