MuSR: 3He Refrigerator Autorecondensing

[JamesKingWork]

As a MuSR scientist, I would like to be able to enable the IOC to check whether a recondense is required and if it is the IOC recondenses automatically. I would also like to be able to define the values used for autorecondense condition checks.

Acceptance criteria:

• When recondense required conditions are met then a recondense is triggered
• When recondense required conditions are not met then a recondense is not triggered

Recondense conditions:

All of the first set of conditions must be met:

• ITC503 is using the control channel chosen for the He3PotLo
• He3PotLo Setpoint < Use He3 below operational parameter defined by user/scientist
• Autorecondense enabled by user/scientist

One of the second set of conditions must be met:

• Sorb temperature check is enabled (by user/scientist) and Sorb temperature > condense threshold for the sorb temperature defined by the user/scientist
• He3Pot temperature check is enabled (by user/scientist) and He3Pot temperature > condense threshold for the He3 Pot temperature defined by the user/scientist
• Temperature error check is enabled (by user/scientist) and the difference between He3Pot temperature setpoint and He3Pot actual temperature > condense threshold for temperature error defined by the user/scientist
