Joe Kerwin (CAPCOM)

Okay. Next was “Circuit breaker panel 16, INSTRUMENTATION SIG SENSOR, CLOSED. Then INVERTER 1, SELECT. Then HELIUM MONITOR to SUPERCRIT PRESS. Report SUPERCRIT PRESS to MCC.” Over.
-
Joe Kerwin (CAPCOM)
-
13, Houston. You're coming through. We still have some background noise. Do you want to read back step 7?
-
Joe Kerwin (CAPCOM)
-
Okay. The last part of step 7 is, “Report SUPERCRIT PRESSURE to MCC,” and read back step 7.
-
Fred Haise (LMP)
-
Okay. Step 7. Circuit breaker panel 11, AC BUS B, HELIUM PQGS DISPLAY, CLOSED. Main—Circuit breaker panel 11, AC BUS B, NUMERIC LIGHTING, CLOSED. CD panel 11, AC BUS—Is that AC BUS B? BUS TIE INVERTER 1, CLOSED?
-
Fred Haise (LMP)
-
And CB—CB EPS INVERTER 1, panel 11, CLOSED. CB panel 16, INSTRUMENT SIGNAL SENSOR, CLOSED. INVERTER 1, SELECT. HELIUM MONITOR to SUPERCRIT PRESSURE. Report pressure to MSFN.
-
Joe Kerwin (CAPCOM)
-
Okay. That's correct. Now step 8 is, “On MCC request, perform step 9.” In other words, you wait for us to decide what to do and that's according to the gouge we've already given you. And step 9, I'll give you now, is “HELIUM MONITOR to OFF, INVERTER to OFF.” Over.
-
Fred Haise (LMP)
-
Okay. Step 8 says, “Set in an MCC hold.” Step 9 says, “On MCC' s words, HELIUM MONITOR OFF, INVERTER OFF.”
-
Joe Kerwin (CAPCOM)
-
Roger. That's correct. Step 10 is, “Configure circuit breaker panels per Activation 3 and 4.”
-
Fred Haise (LMP)
-
Okay. Configure—step 10, “Configure circuit breakers per Activation pages 3 and 4.”
-
Joe Kerwin (CAPCOM)
-
Roger. That's correct. Step 11 is, “Deactivate the utility lights if you activated them,” and step 12 which is the last one is, “Transfer to CSM power, usual observations, and report time to MCC.”
-
Fred Haise (LMP)
-
Okay. Step 11, “Deactivate utility lights.” 12, “Transfer to CSM power and note the usual observations and report the GET.”
-
Joe Kerwin (CAPCOM)
-
Okay. That's it. And, of course, Houston will be requesting you to go to step 9 if the pressure is less than 770. If the pressure is between 770 and 800, we will be asking you to do the following, if you're ready to copy.
-
Joe Kerwin (CAPCOM)
-
Roger. We'll hold off on that. It was a short three-step procedure which said, “Repeat activation pages 1, 1A, and 2,” but there was another step in it that nobody understands. So, essentially what we'd recommend in that case would be that you would repeat the procedure that we just passed up for reading the SUPERCRIT pressure. If we need to, we'll clarify it later on. And that's all we've got.
-
Jim Lovell (CDR)
-
Okay. One thing, Joe; I just want to doublecheck again. All the stuff that normally was going to start at 57 hours, which the first item was pressurize CSM to 5.7 psia, we're going to move that up to 64 now, so we have our LM entry which was nominally at 58 at 55. Is that correct?
-
CapCom
-
Roger, 13. Because of the O2 tank 2 quantity sensor drop out, EECOM wants to keep a little closer track of the cryo quantities, and he's going to be asking you to stir all the cryo tanks at slightly more frequent intervals than had been planned, and the first time is now, and we will be calling you probably every 5 or 6 hours, except during sleep period and high activity periods. We'd like you to do it now. Over.
-
Vance Brand (CAPCOM)
-
Jim, just an advisory; expect a CAUTION AND WARNING on H2 tank 1 pretty quick. No problems; Just warning you about it.
-
Fred Haise (LMP)
-
Well, it's time for a little grits again here, Vance.

Vance Brand (CAPCOM)
-
Roger. Just expect that same CAUTION AND WARNING to come on again. And you want us to keep warning you of that thing?
-
Vance Brand (CAPCOM)
-
Roger, Jim. Just expect a CAUTION AND WARNING to come on the same as it did about an hour ago.
-
Jim Lovell (CDR)
-
Okay. Read you good now. Seems like we've had a little trouble with the COMM today.
-
Vance Brand (CAPCOM)
-
Yes. I guess it's partly because you are further out. We just wanted to tell you that you were going to get that CAUTION WARNING that you just got.
-
Vance Brand (CAPCOM)
-
And I won't bother you with those calls anymore, unless you especially want them.
-
Jim Lovell (CDR)
-
That's okay, Vance. You don't have to call us about that, unless it's something serious.
-
Jim Lovell (CDR)
-
Right, we're not doing anything right now, Vance, we're just getting curious, we could start the LM entry procedures, and get everything squared away, and then when the TV comes up at 55 hours, we can just use it for the TV, and we wouldn't be worrying about checking out the SHe tank pressures and everything like that.
-
Jim Lovell (CDR)
-
Also, Houston, Apollo 13. We'd like to move up the waste water dump and maybe the O2 fuel cell purge a little bit early, if we could.
-
Vance Brand (CAPCOM)
-
Jim, you're clear to go on into the LM, and just advise though that the TV time is still fixed at 55 hours, and—so we'll be standing by to support your entry and we'll get back with you on a minute—in a minute on the O2 fuel cell purge and the waste water dump.
-
Vance Brand (CAPCOM)
-
And also request your LM/CM DELTA-P which was on the flight plan for 53 hours. What did you vent it down to? Over.
-
Jim Lovell (CDR)
-
We'd like another confirmation, when we closed the tunnel vent valve back to LM/CM DELTA-P, we were reading about 1.7—1.75, and it slowly went up now to about—oh, I'd say a little less than 2.2. Seems to be holding there—Is there a lag in the gaging system?
