thanks grizzly, a bit of reading to do before i go back to furthur diagnose- i had 110v on each fused input on modules but i was a bit busy swapping condenser fans on a quoted job, so will pop back next week
cant give u any rep points for that as i need to spread them out:confused:

Hi grizzly,
I have seen the same alarm from last two year on the display of one of my RTAA chiller. With this alarm chiller is working normally.

hi install, you mean disable or enable.rtaa circuit A&B are working without tripping.

with circuit a and b enabled to run on the tracer, if the demand is there then when it asks for circuit a to run then the fault message occurs, when i go into custom report i get the option to reset fault history on circuit a then circuit b then an option to do a reset of the chiller, after completing all 3 resets it still wont allow circuit a to run, circuit b starts up and runs ok, nothing has been touched on the chiller, all cabling between modules appear ok, all fuses on pcs ok, 110v on each,ok

update on system- after visiting site to bash filters, decoy - to check that chiller armed with info off grizzly(ta) bloody thing all working , no alarms , so possibly external component causing grounding that has since dried out.
did check the signing in book to see if anyone has visited and i was the last visitor. back on site in january so will moniter
