They broke it!

Well that sucks man, one of your lift pump motors failed? Looks like you had a lot of rain too, probably starting to overflow on you as well now or at the very least: working your other lift motors harder?

Ultrasonic level sensor and or Hydroranger is bad. It will read ok for a bit and then go to an insane high level and trip alarms. Alarms are now deactivated and a couple of pumps in hand. I’ll come back and check it later.

Ah! Well that sucks man! Ive seen the ultrasonic transducer begin scaling wrong like that too, like it wasnt calibrated right in a the sump pump well of small WWTP ( or so i thought). It would get a lot of rain water and begin rising the levels, instead of kicking them on as a failsafe, it would just overflow out of the well. The plant manager had to keep going into hand mode like you did here.

Turns out it was programmed wrong in the two VFDs it was controlling. It would drain the well past its minimum level in a normal condition, to where it risked burning the motors up from running dry almost and then let it overflow in a high level condition like a storm with heavy rain.

Ed Zachary!

I power cycled it and ran through the program a couple of times.

It will be fine and then randomly throw very high level measurements.
 
Put out a public warning .....you can not take a poop because I ain't working today:rolf:

Yeah, I'd call that wrong too and I dont have a clue what you just said...:blink:

Lol i dont either, its still early and im a lil off my game from sunburn yesterday.

Nah, you have a sensor that scans a tank or well from above, by sending out an ultrasonic signal, which measures how much liquid ( in this case, waste) is in it. It usually has limits set, like what is the minimum level it needs for the pumps to run without going dry and burning them up and then setpoints when they need to turn on to begin removing the amount in the tank. If its a lot and more waste is coming in quickly, it'll try to run more pumps at once to keep up.

But what sucks is everything is dependant on it working and being accurately calibrated. But of course, in time things will mess up eventually. @CoyotesGator here though knows these better than i ever will and could probably do this blindfolded lol
