Hi
my controler is coming up with the p5 fault which i know it does when i stop the flow {i have a pure freedom trolley by the way but i use it in the back of the van with a tank} but it is doing this even when i am connected up and ready to go.there is no noise coming from the pump does this normally mean the pumps goosed or the controler and is there a way to check it i have put an old car battery on charge and am going to wire it up direct to the pump tommoz just to see what happens.if you ran the pump with no controller and just stopped the water with a inline tap by the pole is the pump going to knacker up because the water has no where to go or is it ok to do this
cheers in advance
PS means Pressure Switch - The controller is telling you that the pump pressure switch has activated due to High pressure build up in your system.
If PS is displayed, this means that the pump's pressure switch has been operated due to a high build up of pressure in your system. The controller is set to work with a 5.2 litre per minute pump up to 100psi, although it will work at higher ranges. Common causes for the pressure switch operating are:
1. A restriction to the water flow, i.e. from a twisted hose.
2. Blocked or small water jets. (We recommended that the jets are no smaller than 2mm).
3. Grit or dirt trapped in the system.
4. Air trapped in the system.
5. Prolonged shut off of the water flow.
6. Check the pump pre filter is clear and not blocked
The controller is not activating the pressure switch it is however providing information that something in the system is creating very high pressure in almost all cases it is some type of blockage or air lock.
It may also be worth running auto cal as your calibration setting may be to high.

Another facto to consider is running flat out the pump motor will get very hot, The hotter it gets the less efficient it is at pushing water, As current is turned into heat the pump tries to work harder drawing more current.
