Okay, Jack. That's going to take 120 amp-hours out of the LM, which is equivalent to 10 hours, which will put us back to 193 hours, and that's plenty.
- Jack Swigert (CMP)
-
Okay. Let me relay that to Jim here. It'll be 120 amp hours, which leaves us—which puts us back from 203 hours … to 193 hours.
- Fred Haise (LMP)
-
Okay, Jack. One question here. If we have any problems setting up this LM power to the CSM, is the quickest way to get out of it, return to the normal configuration, as it is for me to just switch the LM POWER to CSM to RESET then OFF?
- Jack Swigert (CMP)
-
I would like to give one quick step in case that gave Jim report some sort of problem for us to get out of it quickly.
- Jack Swigert (CMP)
-
Okay. Real fine. And while you guys are talking it over, you might read back—have you got the procedure for reversing this? I'll copy that.
- Jack Lousma (CAPCOM)
-
Yes. We're still here, Jack. What we want to do is follow you through on this, so we're going to get high bit rate to do it. In answer to your question, to undo this procedure quickly, in the event a problem develops, be sure that you don't touch the 124 POWER switch because it's got a RESET position. But the way to undo it is go into the CSM and on panel 5 open two circuit breakers. And they're some of the first ones we read to you. Open LM POWER-1 MAIN B, and open LM POWER-2 MAIN B. You copy that?
- Jack Swigert (CMP)
-
Okay. Understand. If I want to get out of this real quickly, I have to open just two circuit breakers in the CSM; that's on panel 5, LM POWER-1 MAIN B, LM POWER-2 MAIN B.
- Jack Lousma (CAPCOM)
-
Okay. And before you go ahead with this, let's establish high bit rate and wait 1 on that. And then as we go through the procedure we want you to wait when you get power on MAIN B so we can take a look at MAIN B without any loads on it before we start charging the batteries.
- Jack Swigert (CMP)
-
Okay. I understand you want high bit rate on the LM or CSM just before we start this?
- Jack Lousma (CAPCOM)
-
Okay, Jack. Before we go ahead with this, what we want to do is read you the reverse—the normal reverse procedure.
- Jack Lousma (CAPCOM)
-
Okay. First you want to reverse the battery charge procedure. To do that, on panel 3, switch BATTERY CHARGE, off; AC INVERTER 2, off; panel 5, MAIN BUS TIE BAT Alfa Charlie, on, up; panel 250, circuit breaker BAT Alfa, POWER ENTRY, and POSTLANDING, open. Read back.
- Jack Swigert (CMP)
-
Okay, Jack. On panel 3, BATTERY CHARGER, off, AC INVERTER 2, off; on panel 5, MAIN BUS TIE Alfa Charlie, on; panel 250, CB BAT A, POWER ENTRY and POSTLANDING, open.
- Jack Lousma (CAPCOM)
-
That's affirmative, Jack, and then if you'll go back to the rest of the circuit breakers on that list, and just opposite—Open them all up. Stand by 1.
- Jack Lousma (CAPCOM)
-
Okay, Jack. Go back to the battery charge procedure I gave you. And, in order to terminate charge, just—You'll just have to write “Open” or “Off” next to the circuit switch that I gave you. So on panel 250, that circuit breaker you've already opened; on panel 275, INVERTER POWER-2 MAIN B, open; panel 5, BAT RELAY BUS BAT A, open; EPS SENSOR UNIT AC BUS 2, open, EPS SENSOR SIGNAL AC2, open; BATTERY CHARGER, MAIN B, open; BATTERY CHARGER AC POWER, open; BATTERY CHARGER, BAT A CHARGE, open; INVERTER CONTROL 2, open; INVERTER CONTROL 3, open; you've already done the MAIN BUS TIE; and then BAT CHARGE switch to AC 1. Over on panel 3, you have already set the AC INVERTER 2 to OFF and then INVERTER 2 AC BUS 2, OFF; AC BUS 2 RESET to OFF. You have already put the BATTERY CHARGER switch to OFF; and your DC Indicator select to MAIN B. Over.
- Jack Lousma (CAPCOM)
-
No, if you've got something in the right-hand column for all of those, we don't want to have to do it. And now one more thing I owe you is how to untransfer LM power to the CSM, and I'll get that for you in a jiffy.
- Jack Swigert (CMP)
-
One thing I guess you probably all have considered it, but what heavy things can we store down there where the SRCs normally go to help increase our L over D?
- Jack Lousma (CAPCOM)
-
I understand the question is what kind of heavy things can you store where the SRCs go.
- Jack Swigert (CMP)
-
Yes. They go down in the LEB underneath the computer, and the heavier things you have down there increases the L over D. We don't have any SRCs, so I was just wondering what heavy things—We could probably put some cameras, television cameras, things like that that normally pretty heavy down there in—that, in our SRC. No, we can't put the in our SRC, but we could put them in that container down there which would help decrease our L over D. Anything else you can think of would be greatly appreciated because we don't even have a throwaway station, so we're down a little bit in L over D.
- Jack Swigert (CMP)
-
What souvenirs? (Laughter) All I've got is a Marine Corps foxhole-digging shovel.
- Jack Lousma (CAPCOM)
-
Okay. This assumes that all the descent batteries are on line and ASCENT BATTERY 6 is on NORMAL FEED, as we said earlier. First thing you do is go in the CSM and look on panel 5 circuit breaker. LM POWER-2 MAIN B, open; LM POWER-1 MAIN A, open; circuit breaker EPS SENSOR SIGNAL MAIN B, open.
- Jack Swigert (CMP)
-
… You got just a little bit scratchy there because of the antenna problem. Let me read this back to you.
- Jack Swigert (CMP)
-
Okay. What I got, Jack, was the procedure assumes that all DESCENT BATTERIES are ON, and BAT 6 is on NORMAL FEED. Now we're going into the LM and on panel 5, we take LM, or CM LM POWER-2, MAIN B, open. And that's as far as I got.
- Jack Lousma (CAPCOM)
-
Okay, the second one is on panel 5 also. Circuit breaker, LM POWER-1, MAIN A, open; circuit breaker EPS SENSOR SIGNAL, MAIN B, open. Okay, read those back for the CSM, and I'll give you some steps in the LM.
Expand selection up Contract selection down Close - Jack Swigert (CMP)
-
Okay. CB LM POWER-2, MAIN B, open; CB LM POWER-1, MAIN A, open; CB EPS SENSOR SIGNAL, MAIN B, open. Stand by 1, Jack.
Expand selection down Contract selection up - Jack Swigert (CMP)
-
Jack, I don't think we ever closed CB LM POWER-1, MAIN A. We closed LM POWER-2, MAIN B, and LM POWER-1, MAIN B. Both of them on MAIN B.
- Jack Lousma (CAPCOM)
-
Okay. On panel 16 circuit breaker, EPS, BAT FEED TIES, two, open; and now you've got to listen real carefully for high volts and low volts, BATTERY 1, HIGH VOLTS, to OFF/RESET; BATTERY 2, LOW VOLTS, to OFF/RESET and then ON: BATTERY 2, HIGH VOLTS, to OFF/RESET and then ON; BATTERY 1, HIGH VOLTS, ON; and then the circuit breaker on panel 16, EPS: BAT FEED TIES, both of them, closed. Read back.
- Jack Swigert (CMP)
-
Okay. On the LM side of the house is on panel 16. CB EPS BAT FEED TIES, two, open; BATTERY 1, HIGH VOLTAGE, OFF/RESET; BATTERY 2, LOW VOLTAGE, OFF/RESET then ON; BATTERY 2, HIGH VOLTAGE, OFF/RESET then ON; BATTERY 1, HIGH VOLTAGE, ON. Panel 16, CB BAT FEED TIES, two closed.
- Jack Lousma (CAPCOM)
-
Okay. That's a good readback. It concludes the procedure going both ways and now we just have to stand by.
- Jack Lousma (CAPCOM)
-
No, we're going to do it pretty soon, but we want to have high bit rate, and we don't want you to give that to us until we tell you.
- Jack Swigert (CMP)
-
Okay. I think I'll go back and try to undamp up there. Do you have anything more for the command module?
- Jack Swigert (CMP)
-
Okay, Jack. Just for curiosity's sake, does FIDO have any information as to whether that helium—that helium tank dump affected our trajectory at all?
- Jack Lousma (CAPCOM)
-
Okay, Aquarius. Our tracking data shows that since the helium dump, our entry angle has not changed from its value of 6.24 and somebody calculated that if we had a propulsive vent, that helium could roughly, at the maximum, only impart a DELTA-V of a half a foot per second or less, anyway. But we're continuing to track and as soon as we get some more info, we'll pass it along.
- Jack Swigert (CMP)
-
They said that it would be a while because they want to get high bit rate. They don't want to put high bit rate. …
- Jack Lousma (CAPCOM)
-
Okay, Aquarius. We're ready. So we want some high bit rate. To do that, go over to panel 16 under COMM and close the PRIMARY S-BAND POWER AMPLIFIER. On your COMM panel -
- Jack Swigert (CMP)
-
Okay. Okay, Jack. Wait 1. While—I'd like to get the whole crew up for this if you don't mind.
- Jack Swigert (CMP)
-
We want to transfer some power—I want to go to high bit rate here first, then want to transfer LM power to CSM, Fred.
- Jack Lousma (CAPCOM)
-
Aquarius, there's no great big rush. If you want to let Fred come up to speed slowly, why maybe that'll help out
- Jim Lovell (CDR)
-
Okay. Jack is showing Fred the procedures. Want to get him familiarized with them, and how to get out of any problems before we proceed.
- Jack Lousma (CAPCOM)
-
Roger. No rush. Just let us know when you're ready. We don't want old Fred-o to slip a gimbal there.
- Fred Haise (LMP)
-
Okay, I guess the only question I have is in the first—the very first portion involving the LM here where it has me turn on the only BAT 6, and then turn off all the DESCENT BATTERIES. Are you still reading me?
- Fred Haise (LMP)
-
Okay, the question is “Only one ASCENT BATTERY BAT 6 on the line,” immediately followed by turning off four DESCENT BATs. Is that correct?
- Jack Lousma (CAPCOM)
-
That's affirmative, Fred. That question has been banged around and we decided to go that way.
- Fred Haise (LMP)
-
Let's see, we will be powering other BUS via the CROSS TIE BALANCE LOADS breaker. Is that correct?
