4 VorTechs, 1 with error code and 1 pump losing communication with PAB?

[rattters]

Hiya

I have 4 Vortechs, 2*40wES, 1*40 gen 2, 1*10wES all connected to the PAB controller.

One of the 40wES has a error code in the 'VorTech overview box' (Error 7) and the MP10 keeps losing communication with the PAB, once it has lost comms it stops, the LEDs on the VorTech wave driver for the MP10 are blue but very dim when it has stopped?

You can see the status of the pumps in the attached image.

P3eX firmware 5.05f

Any help appreciated, thanks.
