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?
