For the hall

note that max ramp rate in the hall is approximately 10V / 20H = 0.5 A/sec
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
