Objectives:

This procedure checks all TAs to look for shorts. It does not use the EGA.

Block Name: tega_mini_checkout.vml Version #: R1 Configuration: Landed Operations: Surface Phase Characterization Assumptions: TEGA can not be turned on below -50C Gas(es) used: None Filaments used: None SW Version (386): V513 SW Version (EGA): V321 Sweep and hop mode version(s): NA Super modes and Sweep modes used: None Sequences used: 1B (& 2B), 3B (& 4B), 1A, 32A(&33A), 34A(&35A)

1) Turn TEGA ON (tega_power_on)

a) Add preheat pause as pass in duration determined by thermal environment

b) Pause 30 seconds between TEGA ON and EGA ON

2) Change model power to Ramp1 for Cal Tank and Manifold Heater

3) Start Calibration Heater regulation at 20C

4) Start TA Manifold Heater regulation at 20C

5) Stop Manifold Heater regulation (~ 3 seconds has elapsed)

6) Turn Calibration Heater regulation OFF (~ 4 minutes have elapsed)

7) HEATER TEST

a) Plumbing 1 – ON Wait 5 secs

b) Plumbing 1 – OFF

8) Call tega_select_oven

9) Setup for TA test a) Turn on engineering readings for TA test b) open door time to 10 sec c) close oven time to 10 sec d) LED min diff to -1 e) Poke registers to setup oven, shield, and t-heater f) Change power model to Ramp2

10) Select Oven 0

a) Open Door – 10 secs (This has a 30 sec timeout for GV_TEGA_TA_DONE)

b) Open inlet – wait 5 sec

c) Close inlet – d) Open Outlet – wait 5 sece) Close Outlet –f) Start Oven fill – Shake for 15 secs (verifies LED operational)

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

g) Close Oven – 10 secs (This has a 30 sec timeout for GV_TEGA_TA_DONE)

h) Poke registers for oven, shield, t-heater (allow enough time to get a linear temperature rise)

i) Turn off power to oven, shield, t-heater for one minute. 11) Repeat 23a-23i through Oven 7, SKIP oven 4 12) Bypass OPEN – Wait 5 secs 13) ass CLOSED –

a) Issue FPGA Register Dump 14) Carrier Valve OPEN – wait 3 sec a) Issue FPGA Register Dump

15) Carrier Valve CLOSE – a) Issue FPGA Register Dump 16) Calibration Valve OPEN – wait 3 secs a) Issue FPGA Register Dump 17) Calibration Valve CLOSE –

a) Issue FPGA Register Dump 18) FPGA Dump to confirm valve states 19) TEGA OFF
