Hey Everyone, I have A JEP-R controller that is controlling my Jandy VS pump. It has been hooked up for 5 years. It is on a breaker that has tripped randomly and I always just turned it back on. The other day I turned the breaker back on and the JEP-R now reads “Fault - Pump not Connected”. I have check the cable connecting the pump and controller. I also swapped out the JEP-R at the recommendation of Jandy but still have the same issue. I checked the voltage and have 120 on each line and 240 across the two. I can’t figure out what the issue is. Any ideas or suggestions?

Welcome to TFP.
Have you ran a new cable between the JEP_R and the pump?
You check the DIP switch settings for the pump controller with the 1 and 2 in the ON position and 3 and 4 in the OFF position?
Otherwise the RS-485 comm port on the pump may have died.

Depends if you have the Gen I pump or GenII if you can replace just the drive or need to replace the motor/drive assembly. Either way it costs almost as much as a new pump...

Lightning strike in the area.
Shorting the RS-485 contacts while working on the pump or JEP-R.
Maybe a power surge.

So the only thing that happens randomly is the circuit breaker tripping. No one was touching anything. How do I know the generation of pump?

Circuit breakers randomly tripping is what some people might call a red flag.
It is quite possible that your replacement pump and all your other pool equipment could be damaged again at any time. Maybe you should determine why your breaker is tripping.
Never been able to find an issue. The breaker trips randomly but not often. Maybe 1-2 times every couple months.
