Okay. That's the panel 8 floodlights. Now we're going to take panel 5 and put the FLOODLIGHT rheostat to FLOOD and the LEB, that's panel 100, FLOODLIGHTS are also going to FIXED. And the purpose of this is to balance up buses A and B.
- Jack Swigert (CMP)
-
Okay. Panel 5; FLOODLIGHTS; you want the rheostat on. Panel 100, FLOODLIGHTS; you want FIXED.
- Ken Mattingly
-
That's affirmative. Okay. On panel 8: circuit breakers EMS, MAIN A and MAIN B, that's two, open.
- Ken Mattingly
-
Okay. That's correct. On panel 5: circuit breaker BAT CHARGE, BATTERY A CHARGE, closed.
- Ken Mattingly
-
All right. Like to take MAIN BUS TIES, two of them, on and up. That's probably a verify.
- Jack Swigert (CMP)
-
Okay, Ken. Wait on that one here. I'm just about to lose you here. Just—I've got to change OMNIs.
- Ken Mattingly
-
Okay. Good. On panel 276: circuit breaker INSTRUMENTATION POWER CONTROL, 3 and 4, open.
- Ken Mattingly
-
All right. On panel 276: circuit breaker INSTRUMENTATION POWER CONTROL, 3 and 4, open.
- Ken Mattingly
-
That's affirmative. Okay. Panel 5: circuit breaker CENTRAL INSTRUMENTATION POWER, MAIN B, closed.
- Ken Mattingly
-
Okay, Jack. We want to put the PRIMARY and the SECONDARY EVAPORATED WATER CONTROL valves to AUTO.
Expand selection up Contract selection down Close - Ken Mattingly
-
Okay. Thank you. All right, the next little step after your water control valves is to perform the CSM RCS preheat. We'll do that on page E/1-5, steps 35 and 37.
- Ken Mattingly
-
That's affirmative. Now back to panel 5: circuit breaker CAUTION AND WARNING, MAIN B, closed.
- Jack Swigert (CMP)
-
Okay, Ken. The COMM from you is awful weak—awful weak, I—I can't—it's CB EPS SENSOR UNIT. Say again, after that.
- Ken Mattingly
-
All right, Jack. That's CB EPS SENSOR UNIT, DC, that's Delta Charlie, BUS A and B, closed.
- Jack Swigert (CMP)
-
Okay. CB EPS SENSOR UNIT, DC BUS A and B, close. And I'll give you the volts and amps.
- Ken Mattingly
-
That's affirmative. Okay, now we're at EI minus 5 plus 05. And, as far as you're concerned, Jack, the command module is using this for information only. This will be the LM doing an Earth-terminator AGS alinement; and at the time of 5 plus 05 is the time they'll be going ahead and releasing their ball. And this will be covered in the LM checklist; it'll be uplinked after this one. At EI minus 5, we perform midcourse number 7. Over.
- Jack Swigert (CMP)
-
Okay. At EI minus 05:05, the LM is making an Earth-terminator aline; and at EI minus 05:00, we perform MCC-7.
- Ken Mattingly
-
That's correct. At the completion of midcourse 7, the LM will maneuver to a separation attitude. And this attitude will be sent up on one of the pads that you're going to get before all the sequence starts. And it'll be flown to the LM ball angles on that pad.
- Ken Mattingly
-
All right. At EI minus 4 plus 40, we want to perform page 1-6, step 39 of the entry checklist.
- Jack Swigert (CMP)
-
Ken, I—I didn't get it. We had to change OMNI's again. Could you say it—the EI minus 4 dash—or 04:40, we do something.
- Ken Mattingly
-
That's correct. Okay. The next is the command module RCS activation, and that's step 4-1 of page E/1-6.
- Ken Mattingly
-
All right, Jack. The next is at EI minus 4 plus 30. We want to verify that the LM is configured for command module RCS hotfire.
- Jack Swigert (CMP)
-
Okay. Let's repeat it. Stand by. Cut out. We've really got a strange attitude, so this is why we are having the COMM problem. Panel 5: CB G&N IMU HEATER, MAIN B, closed.
- Ken Mattingly
-
That's affirmative. On panel 1: ROTATION CONTROL POWER, NORMAL. That's two of them, to AC/DC.
- Ken Mattingly
-
That's negative, Jack. We haven't powered up any of the downlink at this time. You'll be doing this and the command module RCS pressurization both by yourself.
- Jack Swigert (CMP)
-
Okay.
Expand selection down Contract selection up - Ken Mattingly
-
Okay. Now, the next event is going to be the separation of the service module, and these are some LM steps, but so that you will know what is going on, I'll read them to you. The LM will do a LM plus-X of one-half foot per second. Then you'll be hitting the CM SM SEP on and up, on their command. As soon as we are free of the service module, the LM will do another LM minus-X for 0.5 feet per second. This is called the push-pull maneuver. I think it was described this afternoon.
- Ken Mattingly
-
Okay. I just wanted you to know that's the sequence you're in. Okay. At the completion of that, we go back to panel 8, and it's SEQUENTIAL, PYRO ARM, both of them, to SAFE.
- Jack Swigert (CMP)
-
Okay. Panel 8: SEQ LOGIC, two, to OFF. Are they ON now, Ken? I don't remember turning them—I guess that's part of one of the other sequences, huh? That we turned them ON?
- Ken Mattingly
-
That's affirm. The reason we're turning the logic off, Jack, is a power savings. So we'll be turning them off, and I'll be getting them back on when we go to get off of the LM; and then turn them back off, then we'll be turning them on prior to entry. Just so you know what's coming.
- Ken Mattingly
-
Okay. Then following this, the LM will pitch up to acquire the Moon—Excuse me, they're going to pitch up and acquire the service module and photograph, and they'll be using the ACA for rotations from now on. And you may see the LM out of window number 5 at the same time they pitch up to acquire it.
- Jack Swigert (CMP)
-
Okay. The LM pitches up, acquires the service module and photographs it, and I should expect to find—might possibly see the service module out of window 5.
- Ken Mattingly
-
That's affirmative. Okay, now we're down to EI minus 3 hours, or the next time-event, and the LM starts a maneuver to what we call the Moon-view attitude. This maneuver is designed to place the command module optics pointing with zero zero at the Moon, and it will be flown to on the LM ball angle.
- Jack Swigert (CMP)
-
Okay, the LM maneuvers to the Moon-viewing attitude which would place the Moon in the center of the command module optics with them at zero zero.
- Ken Mattingly
-
That's affirmative. Okay, now we're going to panel 5, and it's circuit breaker G&N, COMPUTER, MAIN B, closed.
- Ken Mattingly
-
That's affirmative. Now you're going to come up with a 37 ENTER 06 ENTER most likely on the computer. And what we want to do is to put the computer to standby; if you come up with a 37 06, you'll have to do an ENTER in order to get the code 62. If it's got 62 on it, you can do a PROCEED until the DSKY blanks. You might remember that the AC is still off at this time so you won't be getting the STANDBY status light, and your cue that the computer is indeed in standby is when the DSKY goes blank.
- Jack Swigert (CMP)
-
Okay. You're saying that I will probably get a PROGRAM 06 with a VERB 37 ENTER flashing.
- Ken Mattingly
-
Yes. We think that you're going to come up with a 37 06 already in the DSKY. If you do, do an ENTER and that should take you to the code 00062, which is the request for standby. And when you get that, hit PROCEED until the DSKY blanks. If you come up with something else, that's where we want to end up anyhow. With either, when you get the code 62 when it comes up, just do a PROCEED on it.
- Ken Mattingly
-
I don't believe so, Jack. That's one that when you get to that step, if you do get something else, we will be standing by to see that you see. The whole scheme is to go to standby.
- Ken Mattingly
-
Okay. Now, we're at EI minus 2 plus 30; we're going to panel 5: circuit breaker ESSENTIAL INSTRUMENTATION, MAIN A, closed.
- Ken Mattingly
-
Okay, Jack. And that's correct. I got it out of sequence. Would you put that COMPUTER, MAIN A, ahead of LM POWER?
- Jack Swigert (CMP)
-
Okay, Ken. That's CB G&N, COMPUTER, MAIN A, closed, goes before CB LM POWER-1 and -2, open.
- Ken Mattingly
-
That's correct. Jack, what we're doing is we've had the LM powering MAIN B, and we've had all these particular loads on it, and we're getting ready to secure LM power so we wanted to make sure that essential things like the computer, the platform, and all have dioded power supplies before we remove the LM power.
- Ken Mattingly
-
Okay. Thank you. All right, now panel 275: circuit breaker MAIN B, BATTERY BUS B, closed.
