Spectrometer Rotation Reset

This is how to reset the spectrometer rotation controls.

You *must* have explicit permission from Steve Lassiter to do this operation.
No exceptions!

• Locate the HMS rotation control box on the beam-right side of the HMS carriage

• 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 (be careful of the angle camera!)

• 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'

• Call the Counting House and ask for them to try rotating the problematic arm(s). If it works, go back upstairs.
