Vance Brand (CAPCOM)

Jim, regarding your number 2 battery, we think that it's probably a sensor failure, a temperature sensor failure that's caused this alarm, rather than an actual overtemp of the battery; the reason being that we haven't seen any higher temperatures in the glycol loop. We expect to put the battery back on about 101 hours. That'll be about 10 minutes, and then we'll look at it some more there. Over.

Jim Lovell (CDR)

Okay. Concerning number 2 battery, you think it might be a sensor failure because you haven't seen any changes, and you're going to put the battery back on the line in about 10 minutes.

Jim Lovell (CDR)

For information, Vance, about a half hour ago, I guess, Jack and I couldn't see constellations at certain spacecraft attitudes, stars. We could see the—Scorpio and Sagittarius and we could see Altair or Acrux and Alpha Centuri, Vega, stars of that magnitude, and our venting has stopped which allows us now to differentiate between the particles and the stars.

Vance Brand (CAPCOM)

Roger; copy. Understand you can see the stars pretty well. Were you, at that time, in an attitude facing away from the Sun? I presume this is very attitude critical.

Jim Lovell (CDR)

Yes. It is somewhat, Vance. If we have the Sun shining off the quads, it sort of ruins our vision; and also, if the Earth or the Moon are in the general field of view, we can't see anything.

Vance Brand (CAPCOM)

Jim, we're ready to put that battery back on the line. Request you open the CROSS TIE BAL LOAD circuit breaker, panel 16, and then put back—BAT 2 back on the line.

Jim Lovell (CDR)

Okay. First of all, we'll open the BALANCE CROSS TIE breaker on panel 16.

Jim Lovell (CDR)

Okay. The CROSS TIE BALANCE LOAD circuit breakers is in now, Vance. Now you want us to put battery 2 back on. Is that affirm?

Vance Brand (CAPCOM)

Did you say it was in, or did you pull it out?

Jim Lovell (CDR)

No. It's in; do you want it out?

Vance Brand (CAPCOM)

That's affirm. We'd like it out, and then BAT 2 on the line.

Jim Lovell (CDR)

Okay. Coming up. BAT 2 is on the line. We have a MASTER ALARM and a BATTERY light.

Vance Brand (CAPCOM)

Copy. And—and we think that's probably an indication of the sensor problem, but stand by.

Vance Brand (CAPCOM)

Jim, it looks to us like your battery is good, that this is in fact a sensor problem; therefore, request you close the CROSS TIE BAL LOADs on—circuit breaker on panel 16. Advise —

Vance Brand (CAPCOM)

— advise that you will not have any malfunction indication on any of your batteries now, but we can watch it from the ground. Over.

Jim Lovell (CDR)

Okay. We'll close the CROSS TIE BALANCE LOAD circuit breaker at this time.

Jim Lovell (CDR)

That's closed, and we don't have any warning on any of the batteries, but you can monitor from the ground.

Vance Brand (CAPCOM)

And, Jim, we have a lengthy procedure here for powering up the CSM and turning on instrumentation so we can check the TM, and this will take a large piece of scratch paper whenever you're ready to copy.

Jim Lovell (CDR)

This is to power up the CSM?

Jim Lovell (CDR)

Okay. I'll tell you what, I'll have Jack get configured. He can copy that down and I'll have him—we'll get the stuff. Stand by.

Jack Swigert (CMP)

Okay, Vance, how do you read the Aquarius?

Vance Brand (CAPCOM)

Okay, read you loud and clear, Aquarius. Is it cool in there now?

Jack Swigert (CMP)

Okay. Yes, it's pretty cool. This is the third officer on this LM crew here. Ready to copy.

Vance Brand (CAPCOM)

Okay. Jack, this is a lengthy procedure, take probably two or three pages. It assumes that you are in your nominal configuration, which was sent up—or in your day-flying configuration, which was sent up to you earlier today.

Jack Swigert (CMP)

Okay. I can verify that we are in that configuration with the exception of panel 382, the water accumulator, which I've left off in case we wanted to get some more drinking water out of the command module, and I'll put those in the proper configuration before we do anything.

Vance Brand (CAPCOM)

Okay. Panel 4: TELCOMM, GROUP 1, to AC1. Panel 5: close the following circuit breakers: ECS, PRESS GROUP 1, MAIN B; ECS, PRESS GROUP 2, MAIN B; ECS, TEMP, MAIN B; ECS, SECONDARY LOOP TRANSDUCER, MAIN B; ECS RAD, CONTROL/HEATERS, MAIN B; BAT RELAY BUS, BAT B; BAT CHARGER, BAT B, CHARGE—or to B, CHARGE; INVERTER CONTROL, 2; INVERTER CONTROL, 1; EPS SENSOR SIGNAL, AC1; EPS SENSOR SIGNAL MAIN B; EPS SENSOR UNIT, AC BUS 1; WASTE/POTABLE WATER, MAIN B; INSTRUMENTS, ESS, MAIN B; that's ESSENTIAL, MAIN B. Are you with me?

Jack Swigert (CMP)

Okay, Vance. Are you with me?

Vance Brand (CAPCOM)

Roger. Why don't you read that group back, and then we'll proceed on.

Jack Swigert (CMP)

Okay, sounds good. Because I don't know where I—how far I lost you. Okay, panel 4; TELCOMM, GROUP 1, to AC1. On panel 5, close the following circuit breakers: ECS, PRESSURE GROUP 1, MAIN B; ECS, PRESSURE GROUP 2, MAIN B; ECS, TEMP, MAIN B; ECS, SECONDARY LOOP TRANSDUCER, MAIN B; ECS RAD, CONTROL/HEATERS, MAIN B; BAT RELAY BUS, BAT B; BAT CHARGER, BAT B; INVERTER CONTROL, 2; INVERTER CONTROL, 1; EPS SENSOR SIGNAL, AC1; EPS SENSOR SIGNAL, MAIN B; EPS SENSOR UNIT, AC1; WASTE/POTABLE H2O, MAIN B; INSTRUMENTATION, ESSENTIAL, MAIN B.

Vance Brand (CAPCOM)

Okay; That's all correct. Is that reading rate okay for you?

Vance Brand (CAPCOM)

Okay, and leave a little space if you can to the right of these because when we talk about the backup procedure, why then we can just use the same listing, and I'll—I'll tell you open instead of close these circuit breakers, or at least most of them. Over.

Vance Brand (CAPCOM)

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)

Hey, Vance, just a minute. Slow down, would you?

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?

Vance Brand (CAPCOM)

That's right. That's —

Jack Swigert (CMP)

CB BAT B POWER ENTRY -

Vance Brand (CAPCOM)

Okay. That should be BAT Charlie.

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.

Jack Swigert (CMP)

Okay. BAT Charlie POWER ENTRY/POSTLANDING.

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)

How do you read now, Jack?

Jack Swigert (CMP)

Okay, Vance. Did you—how far did you—did you copy any of my steps there?

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)

Roger. The readback's correct, but let me recheck that. Stand by.

Vance Brand (CAPCOM)

Jack, we were incorrect on panel 5; that should have been panel 3.

Jack Swigert (CMP)

Okay, that's good. I got it.

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.

Jack Swigert (CMP)

Go ahead. You want—Repeat the one on panel 3 again, Vance.

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.

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. How do you read on AFT OMNI?
