I am working on an mce Imc and I do not get a run enable I've swapped the ddp board the dio board and the das board with known good boards I have all my correct voltage but still no run enable. On the F3 screen under faults I have a pps fault. I get all my directional relays when I try to run on inspect and if I try to run on test I get directional and high speed relays. Anyone have any ideas MCE seams to be stumped also

Sean,

Google Motion Control Fault PPS and it’ll direct you to the MCE site, first hit it the entire big book.
Scroll down to Table 6.10 and it’ll start you off on an understanding of what PPS is, then you’ll have to go from there.
That board with the 6 potter brumfield relays will give you drive grief as well as those NO/NC auxiliary contacts on the PM or M relay. Everything on the selector has to be right to get the profile ready to enable a run. There is a triac on that board with the 6 relays (Q1 or 4?) it might be bad. Swap it out with another up in the call circuits unless you’ve got serial link type controls, or find another and swap it to prove if it’s goid or bad. NOTE: be careful of the orientation of the triac when reinserting it.

When posting your trouble, go to the general questions area and you’ll get the whole audience looking at your issue.
