00506 Temperature deviation during initial pump-down in TV
chamber test

 

GLAT1832

GLAT1835

NA OPEN Temperature deviation during initial pump-down in TV chamber test. During this test thermo-controlling unit was commanded to +25C at the beginning of pump-down, however , if chiller did not get commanded after this point it can lockup and temperature will drift. In this case temperature went to -9C and flight hardware was not powered. This condition was automatically reseted by transition to +60C. As correction to this new version TV control software does active control during all pump-down period.
00507 TEM/TPS GLAT1835 Assigned (cullinan, 6/2/05) Replace locking helicoil per print. Record lot # of helicoil on W.O. 669 for s/n GLAT 1835.

OK to proceed to I&T testing. Helicoil must be installed prior to integration of GLAT 1835 into Grid. Report completion of helicoil installation to this NCR.
IS: Helicoil (#8-32) was removed during dissassembly of the TEM/TPS module from the T/V test plate


S.B.: Not removed
