TEGA OFB –Acquire no ramp

Reconciled with blocks: Tega_prepx_ofb.r3405 Tega_acq_ofb Objectives:

Power on and receive the OFB delivery to TEGA. Close the oven if oven full is positive. Do no run HT ramp

Note: This block will run at LOW emission.

Configuration:

Sample Planned for Acquired on Sol 122.

Inputs: Oven Close Time: 20 mins for Sol 120 Select TA #: 2

Constraints: TA2 door must be open. Currently verified open in tent configuration. Gas(es) used: None Filaments used: 1 SW Version (386): V515 SW Version (EGA): V321 Note: TEGA is checked to see if TEGA is safed. If so, abort self to end activity

1. Turn ON TEGA – Call TEGA_power_on – This is controlled by the interop science master

1.1.1. TEGA_MAIN1_PWR "ON"
1.1.2. TEGA_MAIN2_PWR "ON"
1.1.3. TEGA_MAIN3_PWR "ON"
1.1.4. Start the TEGA 386 FSW

TEGA_PREP_FOR_XFER STARTS HERE: reconciled with block R31_Sol___

  1. Pause 3 mins
  2. Call Sequence 30A
  3. Set up LED Ignore Diff Parameters (this has been updated to 20%)

Updated to 10hz – 100hz, bin duration 2 seconds

END OF TEGA_PREP_FOR_XFER SAMPLE_PROCESS STARTS HERE

Select Oven TA__2_ –TWEAKABLE

    1. Start shaker – Call tega_fill_oven(We will measure residuals during shaking)
    2. 5.1. shake duration = 180 seconds
    3. 5.2. shake cool down = 180 seconds
    4. 5.3. fill_cycles = 6
  1. Wait for shaker to complete
  2. Initiate oven close (20 mins TBR)

Note: If we do not get oven full TRUE, do NOT Safe TEGA. Shut down

8. Turn off TEGA: CALL tega_power_off

8.1.1. Turn off the third TEGA switch

8.1.2. Turn off the second TEGA switch

8.1.3. Turn off the first TEGA switch

8.1.4. FPGA Dump – Aker Valve state
