All systems (except h1psl0) were upgraded to RCG2.8.5 last week after the power outage. RCG2.8.5 has the bug fix which permits the IOP to disable the SUS DAC anti-imaging chassis via a keep-alive signal outputted from the 18bit DAC card.

Today we tested the control of the AI chassis using the ETMY/TMSY suspensions system via the IOP model h1iopsusey. Jeff K and Arnaud P gave us permission to use the EY suspension systems.

All the tests passed.

Here is what we did:

1. used guardian to put h1susetmy and h1sustmsy into the SAFE state
2. verified all AI chassis were active (green LED on back are ON)
3. killed the models h1susetmy and h1sustmsy, verified that now no models were using any DAC channels, the IOP model deactivated the AI Chassis, relays were heard to close, green LEDs all went OFF.
4. started the models, untripped the user watchdogs. Verified that now models are using the DAC channels, the IOP activated the AI Chassis, green LEDs all ON.
5. bypassed the SWWD on h1seiey so if the SUS test exceeded 5 mins the SEI system would not trip
6. PANIC crashed the TMSY SWWD, verified all the AI chassis were deactivated (green LED all OFF)
7. removed the PANIC and RESET TMSY SWWD, verified all the AI chassis were activated (green LEDs all ON)
8. PANIC crashed the ETMY SWWD, verified all the AI chassis were deactivated (green LED all OFF
9. removed the PANIC and RESET ETMY SWWD, verified all the AI chassis were activated (green LEDs all ON)

This concluded the test. The BYPASS on h1seiey was removed. Guardian put both ETMY and TMSY into the DAMPED state.
