Okay. Next, panel 3: TRANSPONDER, PRIMARY; POWER AMPL, to PRIMARY, that's a verify; POWER AMPL, HIGH; MODE, VOICE, to OFF; POWER, SCE, to NORMAL; PMP to NORMAL; S-BAND ANTENNA, OMNI D, that's Delta. Okay, why don't you read that one back?
-
Jack Swigert (CMP)
-
Okay. On panel 3: TRANSPONDER to PRIMARY; POWER AMPLIFIER to PRIMARY; POWER AMPL, HIGH; MODE, VOICE, to OFF; POWER, SCE, to NORMAL; PMP to NORMAL; S-BAND ANTENNA, OMNI D, D as in Doggy.
-
Vance Brand (CAPCOM)
-
Hey, very good. Okay, panel 225: circuit breaker FLIGHT BUS, MAIN B, to close; circuit breaker CTE, MAIN B, to close. Panel 250: CB BAT C BAT CHARGER/EDS 2 to close.
-
Jack Swigert (CMP)
-
Okay. I got distracted here. On panel 225: CB FLIGHT BUS, MAIN B, close; and then I lost you after that.
-
Vance Brand (CAPCOM)
-
Okay. After that, CB CTE, MAIN B, to close. Next, panel 250: CB BAT C BAT CHARGE/EDS2 to close; CB BAT C POWER ENTRY/POSTLANDING to close. Next, panel 275: CB MAIN B, BAT BUS B, to close; CB INVERTER POWER 2, MAIN B, to close. Okay. Incidentally, anything that I've given you up until now is not sequence critical, but from now on, it should be—you should be sure to do it in the sequence we give you. Why don't you read that back, Jack?
-
Jack Swigert (CMP)
-
Okay. Let me give you all of panel 225 again. CB FLIGHT BUS, MAIN B, close; CB CTE, MAIN B, close. On panel 250: CB BAT—B BAT CHARGE, that should be BAT C, Charlie, isn't it? BAT CHARGE/EDS2 closed?
-
Jack Swigert (CMP)
-
Let me finish. Okay. That's what I thought. BAT Charlie BAT CHARGE/EDS2, close; BAT Baker POWER ENTRY/POSTLANDING, closed. On panel 275: CB MAIN B, BAT BUS B, closed; CB INVERTER POWER 2, MAIN B, closed.
-
Vance Brand (CAPCOM)
-
Okay. That's correct except for the second circuit breaker on panel 250, which is CB BAT Charlie POWER ENTRY slash POSTLANDING, close.
-
Vance Brand (CAPCOM)
-
Okay, now back to panel 250. CB BAT Bravo POWER ENTRY/POSTLANDING, close. Next, MDC 3, AC INVERTER 2 to MAIN B. AC INVERTER 2, AC BUS 1, on up. Next, panel 5: AC INVERTER AC BUS 1 to RESET and then center. Panel 3: UP TLM to COMMAND RESET then OFF. Then select best OMNI. Readback, please.
-
Jack Swigert (CMP)
-
Okay, Vance. The following steps are sequence critical. Panel 250: CB BAT B POWER ENTRY/POSTLANDING, closed. That's BAT Baker. MDC 3, AC INVERTER 2, to MAIN B; AC INVERTER 2, AC1, on. …
-
Vance Brand (CAPCOM)
-
Okay, I heard you through AC INVERTER 2, AC BUS 1 to on, and you were cut out by noise. Go ahead.
-
Jack Swigert (CMP)
-
Okay, Now comes to one I didn't understand. You said go over to MDC 5 and A in—AC INVERTER, AC BUS 1, RESET, then center, and then back to MDC 3; UP TELEMETRY, COMMAND RESET then OFF, and then select best OMNI.
-
Vance Brand (CAPCOM)
-
Okay. Now, when you're in this configuration, the following onboard readouts are required. Panel 3: BAT C voltage, PYRO BAT A voltage, PYRO BAT B voltage, SPS HELIUM PRESSURE. And the following readouts on panel 101: CM RCS injector temperatures, those are positions 5 Charlie, 5 Delta, 6 Alfa, 6 Bravo, 6 Charlie, 6 Delta; and the battery manifold pressure, which is 4 Alfa. And standing by for readback.
-
Jack Swigert (CMP)
-
Okay. You want me to read out on MDC 3: BAT B voltage, PYRO A voltage, PYRO B voltage, SPS HELIUM PRESSURE. On panel 101: command module RCS injector temperatures; 5 Charlie, 5 Dog, 6 Alfa, 6 Baker, 6 Charlie, 6 Dog. The battery manifold pressure, 4 Alfa.
-
Vance Brand (CAPCOM)
-
Okay. Now—that was correct but I want to re-check the very first one, that was BAT Charlie voltage. Is that what you read back?
-
Jack Swigert (CMP)
-
Okay. Okay, BAT Charlie voltage. Seems like we're having a difference—I can't understand BAT Charlie from BAT Dog.
-
Vance Brand (CAPCOM)
-
Okay. Now, that—that complete procedure for getting into it, as far as getting into it's concerned. What I will give you now is how to back out of it after you're through with your readings. Are you ready to copy?
-
Vance Brand (CAPCOM)
-
Okay. Now you'll back out fairly quickly after you go into this procedure. All we'll need is about 5 minutes of TM, and so if you're ready to copy, here it comes.
-
Vance Brand (CAPCOM)
-
Panel 3: POWER AMPL to OFF. Incidentally, copy this down on a piece of scratch paper as I read it, and then later I'll refer back to your first list where you can write things in the right-hand margin.
-
Vance Brand (CAPCOM)
-
TRANSPONDER, OFF. AC INVERTER, 2, to OFF. Okay. Next, panel 250: CB BAT Bravo, POWER ENTRY/ POSTLANDING to open. Stand by 1.
-
Vance Brand (CAPCOM)
-
Okay, Jack. What I just gave you now on the backout is the only thing that's order critical. From here on, you can go to the steps for initiating the procedure, and backtrack. In other words, you should go to each of the panels that I read up and put the circuit breakers back to the base-line configuration—or the switches. Over.
-
Jack Swigert (CMP)
-
Okay, now here's—to accent, here's the sequence-critical sets: POWER AMPL, OFF; TRANSPONDER OFF; AC INVERTER, 2, OFF; and the last one on panel 250, CB BAT Baker POWER ENTRY/POSTLANDING, open; and then hit the steps in reverse order that you gave them to me, and back out, like then I would start on MDC 3 UP TELEMETRY, OFF—to OFF; and then AC INVERTER—AC1 BUS 1 to OFF; and then AC INVERTER, 2, OFF; AC INVERTER, 2, MAIN B to OFF. Is that the type of order that you want to back out of?
-
Vance Brand (CAPCOM)
-
That's affirm, but—just for kicks, let's go through these panels again, and I'll give you the—the position, just to make sure there can be no doubt.
Expand selection up Contract selection down Close -
Vance Brand (CAPCOM)
-
Okay. And once again in the—in the area where I said order was not critical, it's still not critical when you back out. But now I'll go ahead. Okay, panel 4: TELCOMM, GROUP 1, AC1, it will not be AC1, it'll go to OFF. Panel 5: all circuit breakers on that panel which were positioned will now come to opened. Over.
-
Jack Swigert (CMP)
-
Okay. Panel 4: TELCOMM, GROUP 1 will go OFF. Panel 5: all the circuit breakers that we closed will go back to open.
-
Vance Brand (CAPCOM)
-
Okay. Panel 3: the first three lines have been taken care of already in my beginning in the backout procedure, so starting with MODE, VOICE, that should go back to VOICE. POWER, SCE, OFF; PMP, OFF; S-BAND ANTENNA, OMNI Bravo. Panel 225: CB FLIGHT BUS, MAIN B, open; CB CTE, MAIN B, open. Read back.
-
Jack Swigert (CMP)
-
Okay, Vance. I'm going to have to switch OMNIs. I'm starting to get some static here.
-
Jack Swigert (CMP)
-
Okay. On panel 3: the first three steps we took care of; MODE, VOICE, to VOICE; POWER, SCE, OFF; POWER PMP to OFF; and S-BAND OMNI would go back to Bravo. Panel 225: FLIGHT BUS, MAIN B, will go open; and CB CTE, MAIN B, will go open.
-
Vance Brand (CAPCOM)
-
That's affirm. The two circuit breakers on panel 250 will go open; the two circuit breakers, panel 275, will go open. Okay, the circuit breakers on panel 250, we took care of already. Panel 3: AC INVERTER, 2, we took care of. AC INVERTER 2, AC BUS 1 should now go OFF. And the remaining two switches on panel 3 we took care of. And “Select best OMNI” remains the same. Okay. Read back.
-
Jack Swigert (CMP)
-
Okay. The two switches—two circuit breakers on panel 250 will go back to open; the two circuit breakers on panel 275 back to open; the POWER ENTRY/POSTLANDING circuit breaker, we already took care of earlier; AC INVERTER 2; we took care of earlier; AC INVERTER 2 to AC BUS 1 will go to OFF; and AC INVERTER, AC BUS 1, we took care of—No, that'll go to OFF; and UP TELEMETRY, COMMAND RESET will go OFF.
-
Vance Brand (CAPCOM)
-
That's correct, Jack. Okay, that's it. And I think we're about ready to go with this procedure whenever you are.
-
Jack Swigert (CMP)
-
Okay. First we got to go through that procedure to power the CSM from the LM, is that Charlie?
-
Vance Brand (CAPCOM)
-
No. No, this is independent of power from the LM. This is a—this is purely a CSM —
-
Vance Brand (CAPCOM)
-
This is purely a CSM powerup so we can take a look at your telemetry and see how cold the vehicle is and that sort of thing.
-
Jack Swigert (CMP)
-
Okay, now I won't—I won't have any voice with you, so—Is that right? You don't want me to get connected up—you want me to just take these readings and come back and tell you what I have, huh?
-
Vance Brand (CAPCOM)
-
I—we presume, though, that there'll be somebody in the LM that we can call if we have to get word to you.
-
Jack Swigert (CMP)
-
Oh, yes. There'll be somebody to be standing by, they'll run up into the bedroom and tell me to stop what I'm doing.
-
Jim Lovell (CDR)
-
Okay, Houston; Aquarius. Switching watches, and Jack's going up into the command module.
-
Vance Brand (CAPCOM)
-
Okay, Jim. We have four steps here to give you to request that you get back on DOWN VOICE BACKUP, if you're ready to copy?
-
Vance Brand (CAPCOM)
-
Okay. Bit rate to LO bit rate. VOICE, FUNCTION switch to DOWN VOICE BACKUP. POWER AMPs CB, open; RANGE FUNCTION switch in RANGING; that's verify.
-
Jim Lovell (CDR)
-
Okay. Bit rate, LO; VOICE FUNCTION, DOWN VOICE BACKUP; POWER AMP S-BAND, open; and RANGE FUNCTION to RANGE; and that's a verify. And I still have the BIOMED on RIGHT here, so we don't have hot mike.
-
Jim Lovell (CDR)
-
And I'm copying down the reestablishing—PTC maneuver that Charlie gave me. Step 5 was, “When rates are less than 0.05 degrees per second, ATTITUDE CONTROL YAW to PULSE.” And just how am I to get my rates down to 0.05 degrees per second. My—My rate indicator, at the best, is 0.1 of a degree.
-
Vance Brand (CAPCOM)
-
Jim, this has been tried in the simulator by Charlie and others, and what they recommend is that you null your rates on the error needles until you see no movement whatsoever, and then wait another couple of minutes, and that should do it. That's the only way we can tell. Over.
-
Vance Brand (CAPCOM)
-
Okay. And if you can't attain that, why, of course, just the best you can do. We'll have to give it a try. Maybe it won't be quite like the simulator.
-
Jack Swigert (CMP)
-
Okay, Vance. I've gone all the way through your procedure—all the way down to “Select best OMNIs,” but I'm not getting any MAIN BUS B voltage and this I don't understand.
-
Vance Brand (CAPCOM)
-
Okay. You faded out due to noise in the orientation. If you close the POWER AMP circuit breaker, we can hear you better. Over.
-
Vance Brand (CAPCOM)
-
Okay. You faded out at the very beginning, so please go through that again. We understand you don't get anything on MAIN B.
-
Vance Brand (CAPCOM)
-
Okay, Jack. Please, repeat back now your conversation. You were cut out for—a while ago.
-
Jack Swigert (CMP)
-
I don't have any idea where we cut out, Vance. I just said that we performed the procedure exactly as you say. We're down into the SEP critical portion to where I said, “select best OMNI.” However, we're not getting any MAIN BUS B voltage reading. I can read BAT BUS B, Baker, at 36.5; BAT Charlie at 37.0, but I have negative MAIN BUS B readings.
-
Vance Brand (CAPCOM)
-
Okay, Jack. There are two—There's a switch and a circuit breaker that were positioned this morning that we'd like to have you check—Correction, just the switch. Panel 5, check your bus tie. MAIN BUS TIE BAT B/C on.
-
Vance Brand (CAPCOM)
-
Okay. We're getting data from you, Jack, so that much looks good. On panel 5, request verification that EPS SENSOR SIGNAL circuit breaker is MAIN B. Over.
-
Jack Swigert (CMP)
-
Well, Vance, if you're getting data from them, let me go back up there and finish the …
-
Jack Swigert (CMP)
-
Okay, Vance. Okay. We just changed OMNIs here. I say, if you're getting data from us, that's the important thing. Let me go back up into the bedroom there and get the readings you wanted, so we can get this stuff powered down. Is that okay?
-
Jack Swigert (CMP)
-
Okay, Vance. We'll go back up—We've got voltage now, and we'll go back up and take the readings that you want.
-
Vance Brand (CAPCOM)
-
Okay. And select best OMNI.
Expand selection down Contract selection up -
Jack Swigert (CMP)
-
Okay. I'm going back up to the bedroom. We'll select best OMNI and continue on with the procedure.
-
Jim Lovell (CDR)
-
And, Houston, I noticed through the AOT and through the overhead docking window that we are venting again.
-
Vance Brand (CAPCOM)
-
Jim, would you holler into the bedroom and tell Jack that when he has his onboard readouts that we wish he'd back—use the backout procedure and shut down again—per the procedure we gave him.
-
Jim Lovell (CDR)
-
Roger. As soon as he—As soon as he gets his onboard readouts to use the powerdown procedure and shut down. Is that right?
-
Jim Lovell (CDR)
-
Okay. Jack just—Jack just told me that he's through, and he's going to go through the backout procedures again, the first one he's got is the shutdown.
