From: Larry Visoski Sent: Sunday, April 1 , 1 11:1 To: Subject: Je vacation GIV update Jeffrey Message from Pete,.below: Dave and I are at airport now in case=you decide to depart earlier than 3.0am„ I suspect that the right precooler (fan air) modulating valve i= bad. They are both original. From the last video and Photo's; The readings show th=t the left side is being given a voltage to the Torque motor sending a=nbsp;pressure to command the valve to be partially closed. Zero volts, zero pressure is for full open, ie: co=d air into the precooler and lowering the temperature into the supply syste=. There is no signal from the valve, the temperature monitoring circuit cont=ols the changes required. The right side shows that it is bein= commanded to close due to the high voltage, and pressures. ( 9 volts, 9 PSI) It seems that the signals are not being followed, or that the val=e cannot respond to them. Since t=e control system does not see the temperature change from the sensors, it c=ntinues to increase the pressure to the valve. Brief complete•=/span> EFTA_R1_00100605 EFTA01781557
