Reconciled with block: tega_door_open\r26

Objectives: Open the TA Door and collect data that permits a calculation of the heat capacity of the female oven half. This version is to be used for TA#4 – Surface Phase Characterization ONLY.

Configuration: This procedure may begin with TEGA off, or it may be tacked on the end of some other procedure.

Filaments used: 0

SW Version (386): SW Version (EGA):

Sweep and hop mode version(s): None

Super modes and Sweep modes used: None

1) TEGA ON (called in interop block)

2) Select oven (as input parameter) Sol _____ TA _______

3) Command TA Door Open

a) Open door default duration is 5 minutes

b) GV_TEGA_TA_DONE timeout is 10 minutes. If timeout does not go true the activity is terminated.

Heat manifolds to ensure pressure sensors work.

4) Start TA Manifold Heater to regulate at 20 C [tweakable]

5) Start EGA Manifold Heater to regulate at 35 C

6) Pause 5 minutes for manifolds to come to temperature

Exercise valves and carrier gas to check out flow and ensure no clogged frits.

7) Call tega_flow_car (executes Seq 90A open/close of carrier valve)

8) Pause 1 minute (to measure leaks)

9) Open bypass valve

10) Pause 1 minute (to check out EGA pressure sensor)

11) Close bypass valve

12) Open oven inlet valve

13) Pause 1 minute (to measure flow rate to ensure frit is not plugged)

14) Close oven inlet valve

15) Set Carrier gas to off: Calls tega_stop_car

16) Open oven outlet valve

17) Pause 1 minute (to empty gas from TA manifold)

18) Close oven outlet valve

19) Stop TA manifold heater regulation

20) Turn manifold heater off

21) Stop EGA manifold heater regulation

22) Turn EGA manifold heater OFF

Check out oven fill and close oven for copper path

23) Start Oven fill – Shake for 15 secs (verifies LED operational)

a) Will not shake/LED Diff Parameters set to prevent

24) Close Oven – 10 secs

a) This has a 30 sec timeout for GV_TEGA_TA_DONE. IF GV does not go true, activity gracefully terminated.

25) Ramp oven as follows: Call tega_ramp (hidden child)

a) Ramp Segments: TA#4 = 0-3A (PIT values are different than Flight Values)

i) -50 to -30 at 20 K/min

ii) Hold at -30 for 1 minute

iii) -30 to -10 at 5 K/min

iv) Hold at -10 for 1 minute

v) -10 to -30 at -5 K/min

26) Shut down (call tega_power_off)
