Spectrometer Rotation Reset Procedure
This is how to reset the spectrometer rotation controls.
You *must* have explicit permission from Steve Lassiter and/or the Hall Leader to do this operation. No exceptions!
Appropriate precautions and PPE must be used when flipping breakers.
Locate the HMS rotation control box on the beam-right side of the HMS carriage over the rail
Disable the rotation control by turning the key from 'Normal' to 'Bypass'
Locate the HMS breaker panel (to the left of the rotation control panel) on the HMS carriage
Turn the breaker labeled 'HMS Drive' (22) OFF, then back ON
Locate the SHMS rotation control box at the rear of the SHMS carriage between the wheels
Note: be careful of the angle camera nearby!
Disable the rotation control by turning the key from 'Normal' to 'Bypass'
Locate the SHMS breaker panel (on the beam-left side of the carriage, under the upper platform, downstream of the stairway).
Turn the breaker labeled 'DRIVE MOTOR/SHUNT TRIP' (39) OFF, then back ON
Call the Counting House and ask the shift crew to reset the rotation controls for both spectrometers.
Re-enable the remote rotation controls in both the SHMS and HMS by turning their keys back to 'Normal'
