Abatement
Why are DEA heads special?
Wedges
What is the most common pump we exchange?
IGX600m
What are the three types of legacys?
TCS, TPU, Helios
Which toolsets have hot traps, and which toolsets have cold traps?
RIO, CSA, CSM have hot traps, VFN have cold traps
When using a DMM, what must you do before each check?
Known, Unknown, Known check
What is the purpose of Maintenance switches?
Turn off LSS Safety Systems near abatements, Turn off outputs on abatements is also an acceptable answer
What if you cannot purge a dead pump? (specifics needed)
Upgrade all PPE, airline and chem suit
What are all the things that must be done to make sure RO is read accurately?
N2 purges off, capped inlet purges off, atomizers off, bypass in offline, CDA off
What is it called when the N2 is always flowing on an IXH? How is it installed?
50 if stop, configs
What is the acceptable leakage rate called, and what does it apply to?
Rate of rise, whole abatement system, not separate parts
What are 4 upgrades from legacy to iatlas?
there are too many
On an IXH1220HTX, what does the HTX stand for? all 3
Heavy duty, Thermal, Corrosion resistant
Why are CDT heads special?
Capped B port, and wedges
What is the tool set, and which specific pump in the frame requires gagging?
RCL Load locks
Why must a pump be allowed to heat up before FP?
Thermal expansion causes the basedown to reach normal operating levels
Why are AVX heads special?
Long throw clean springs and actuators, wedges, and AVX nozzles
What is the name of the exhaust N2 purges?
Dilution purges
What is the correct unit of measurement that the packed tower must be filled to?
300mm below packed tower spray lance
What is the correct names for the procedures and what do you do if the N2 is out of spec on IGX, IXH, and IH pumps?
IGX+IH: Gas module calibration
IXH: One time N2 regulator adjustment
Describe how to do leak checks from pump to abatement
Flow through must be through port A or online purge on bypass, and N2 must be switched off or else grounds of failure
How much SLM per inlet are heads allowed to receive, and what was the solution to this?
50 SLM, crowns and orifices
how do you release control of a system with HIS frames (the actual way)
Press (release control, then choose individual pumps or all)
Describe how to test a snap switch for proper ohmage, and how you would find the one currently alarming out
Anything over .2, or an open load
Accurately describe the whole procedure for shutting down and LOTOing a hot trap
Probably not
Give an acceptable way to verify the water pressure transducer failing, and give the trouble shooting steps necessary to prove it
Too many right ways
