View Full Version : Hussman Protocol broken pressure sensor code
03-29-2010, 10:45 PM
I have a customer with a Hussman Protocol that is running fine, but displaying:
"pressure sensor 2 broken"
Is this referring to the pressure sensor on the #2 compressor?
Are there schraeder cores under the pressure sensor so they can easily be changed?

I was notable to find that display in the manual, maybe youll have better luck if go to hussman web site on the home page there is a search tab type in protocol and in will bring up all manuals on that subject. The only thing I seen on it was Pressure sensor fail display means pressure was greater for a longer period of time then the alarm allows for in other words.

I've had that issue on a protocol and pressure probe 2 is the discharge pressure probe if i remember correct. All of my transducers were mounted on service valves so it was easy to isolate. I think the alarm is if the board loses a signal from the sensor it alarms. I changed the probe out and the problem cleared up. Just have to make sure you use a 4-20mA sensor as the 0-10VDC ones aren't compatible from what I've seen.
