   Looking for reasons that HPD faults occur. High pressure is the obvious answer but what are the common causes? Software programming? Obstruction in pipe? Valves closed? In my particular case the fault occurred towards the end of a cycle. Flowtronex VFD station. Rainbird 700 series heads. Cirrus software. Par+ controllers. Thanks in advance🇺🇸

   Chris,
   I am certainly no pump guy, but how long has the problem been going on for? Is it a new problem or have you been struggling with this for a while? Have you made any changes to your Cirrus software? I'm wondering if you need to tweak the factory set points for HDP or if you have modified your Cirrus setting in any way. Knee jerk thought is if the computer is shutting valves off too fast for the pump to react to the change in flow, pressure rises and hits the fault set point.

   I had a similar problem on my system that was caused by the Cla Valve. If you don't have a Cla Valve I would check all of your set points on the VFD to make sure one didn't get changed.

   Was just having the same issue. I had to readjust pressure regulators on my Pressure Reducing Control Valve. My system has 2 pressure regulators on the outgoing side that control system set pressure and valve reaction. These can get filled with debris and cause control valve to be out of adjustment and cause the system to over pressurize and the end of a cycle or when flow is suddenly reduced due to less demand. Also pressure down and clean all the tubing every month or two depending on your water conditions.

   Thanks gentlemen! This station is actually at a course I consult with and so details are hard to come by as they have no full time superintendent....thanks again for your input!

   As mentioned, check the high pressure dump valve (may be a Clay Valve) to ensure it is allowing the pressure to dump off.

   Have had the springs in these break also.

   Me too. I have to adjust these settings at least once a year. I also have them serviced when they do our pump servicing.

   If its VFD controlled, you shouldn't need a pressure reducing valve (cla or other), and the culprit should be programming. How old is it? does it track pressure and flow? Flowtronex is still in business and should have tech support / service

    I've seen the piping for the pressure transducer get clogged, enough where pressure changes are not accurate. If it holds high pressure for too long it can cause a fault. There should be two types of high pressure faults on a VFD system, the first is in the programing if pressure stays 5-10psi above the setpoint a fault will be tripped and registered on the panel. The second is an actual mechanical pressure switch that is usually set around 15psi higher than the setpoint. This is located on the outside of the control panel. If pressure in the system reaches that point it will shut down the system completely. These switches can also go bad or get clogged.

    It could be any one of the suggestions mentioned. My first thought would be the Cla Valve if you have one. I highly recommend getting a Certified Flotronix repair and installation company to clean it up. Should get one in a day this time of year. Lots of nasty high voltage in that cabinet.
