Download John`s AMS Instrument Developoment

Maintenance
• Pin-hole assembly, check o-rings and
replace with 2-006
• After field mission clean the chamber and
filters on all systems
• Last thing? (don’t know what he said
here)
Questions
• Johannes: Problem with turbo controller on aircraft?
Theirs failed back in the lab. Didn’t restart pump, talked
to Varian for an exchange and thought it might have
been due to temperature differentials.
• John: temperature spec rating says it should be OK
• Keith: also had problems, overheating in Switzerland
• Jose: mounted another fan and that solved the problem,
flashing light is a warning
• James: Alcatel was cutting out, even with fans working,
TSI 3800 might have accentuated the problem.
• John: Only happened when two controllers stacked.
• Alice: Alcatel controller did fail during one flight,
restarted the pump to solve.
