> While downloading new code for 2A PLC the M9 and M15 vacuum systems were > shut off. This is due to the two systems piggybacking onto the 2A PLC. > When M9 Epics came back up there was no controls. Eventually I reset the > local/remote switch (thumbwheel #100) to button #1 being on. Mike Leross > added a text and light on the epics vacuum page that says "EPICS works > only when green". If this light is not green, dial thumbwheel #100 and > push button #1. Make sure the light comes on and you should have EPICS > control back. > > This caused a glitch in the refrigerator system. It did not trip it off, > but it would have if the solenoid was energised. The panel showed > compressor fault and the temps for TI121, and the powerleads all jumped. > This may be a cause for some of our unknown problems.
