Someone please correct me if I get this sequence wrong. MSU picks a direction relay, U or D, P contactor picks through N/C M contact etc. sheet 3. On sheet 8, ENA relay and LED on relay pilot board pick through direction relay and P, CO LED should also light. CO signal goes to drive on sheet 10, picks K2 drive relay, drive picke K3 relay. When K3 and K2 pick, PR contactor pilot relay should pick (H-5) which picks M contactor (D-12)
