Power supplies
Robicons
Located in ESAT basement, need LTX padlock key to access. To enter through C-site MG (new machine shop area), need a key from lockbox. Otherwise, can access by going outside and entering ESAT on the far side of the building.
- DF: Drives the red coils.
- IF: Drives the blue coils.
- T1: Coupled with the PEI, drives the TF coil.
- T2: Drives the internal coils.
- T3: Drives the orange coils.
- T4: Drives the green coils.
Cooling water
Controlled by panel SR7-1 in C-Site MG, use *buttons* to start/stop. Note the breaker that powers the panel is also labeled SR7-1 and is actuated with a handle; this breaker is generally not used.
Front panels
Lights may be burned out, use test button to check
Breakers
If they fail to close, often a vacuum contactor is stuck in one of the Robicons. There is an insulating rod that can be inserted into a small hole in the bottom side of the supply in order to reset the contactor. Afterwards, click "fault reset" on the PLC computer and close the breaker.
Control software
The square buttons indicate a command has been sent, the circle lights indicate the status of the supply.
PEI
Coupled with Robicon T1, drives the TF coil.
Control panel
Powered on only when breaker Q1B5D is closed
Faults displayed on panel. Appears they cannot be reset when in remote control, need to first switch back to local
Disconnects
Connect/disconnect the power supplies to the field coils. Five are manufactured with the brand name "Pringle" while a sixth is "homemade" for the IF supply presently connected to the blue coils. Located in the S-wing basement, need LTX padlock key or front gate key to access, except for the homemade IF disconnect. Powered by breaker in LP ?, which is itself powered by breaker #? in LP 889.
