To-do list
- Wiring
- rewire for coil 2 subcoils
- document trip chains
- label circuit breakers
- Danfysik power supply
- commission new readout channels
- commission fault sequencer
- fix slow dump
- understand ramp-down mechanism
- choose ground fault detection mechanism
- Danfysik quench detector
- Instrumentation
- implement system to isolate fault detectors and determine time sequence of trips - postponed 8-Apr-2011
- monitor circuit breakers?
- VME-based fast DAQ
- real-time graphics
- A-B HMI improvements
- implement fault sequence screens if system implemented
- A-B PLC program improvements
- mods for new coil configuration
- EPICS
- new channels
- EWEB screens
- update for latest tags and drawings
- Auxiliary tests
- Reenable cron job
- when cooldown commences, end when warmed up
For the hall
- note that max ramp rate in the hall is approximately 10V / 20H = 0.5 A/sec
- need travelers for coil installation.
- should we install a UPS on the Danfysik contactor and control boards?
- should we install a second contactor in the Danfysik power supply?
- do we need additional valves, check valves, bypasses, whatever?
- do we need Dataforth voltage attenuators on coil tap channels?
- do we need active isolation of coil tap channels, etc?
- should we monitor all circuit breakers?
- should we monitor all relays?
- what is the effect of B field on sensors/relays? should some instrumentation be relocated?
- do we need new flow sensors, or should they be relocated?
- lock box for power supply key
- more ethernet power strips
- use custom ("add-on") instructions to simplify PLC code
- install permanent VME-based fast DAQ
