|
Anders and I found a low frequency issue(13hz only) on TCS TGHT flow sensor when doing TM4 conditioning. By trouble shooting, We found the module water
lines are good. the restriction cause this problem in on TCS supply or return water lines to TGHT. I switched TGHT lines with MSP water lines. The
wheel frequency on TGHT is 67.0hz which is pretty high. Now, MSP is using the original TGHT water line(flow sensor frequency 13hz). Flow sensors and |

|
Gordon Crane technician Tom Kauss finished the replacement of the east side main hoist brake assembly. A new set up is installed. he adjusted gap too
close during first time try. So, the smell appeared when operate the brake. He increased the gap to a proper distance then. It looks like everything works
fine now. Still, The brake need to be tested with 10K lBS load on it. We will do the load test on next Thursday when he come here to replace west side |

TM#1 has been moved from the conditioning station to the north west silo. There was a slight delay in the move as the limits for the hoist
drum got way out of whack and had to be adjusted. |

Results of an electrical check on TM#1 with no target attached to it.
I use this e-log entry for TM1 notes as well 1. TM1 IG1 is a dual filament gauge . Its filament is very close to grid now. It shorted
one time during the pumping down. It still works fine so far . But, we may need to change it if we use this module in TS again. |
