Log Book for March 22, 2008
Engineering Report
Elisha Sanders Reporting

Generator/Electricity:

Wendy

Hobbs Meter: 3813.5 hrs [ +21.8 hrs since yesterday ]

Voltage: 117 VAC

[*] Frequency: 56 Hz

Oil Level: 7/8

Oil Pressure: 30 PSI

[*] Water Drained: no


Notes/Comments:
The generator was accidentally left on the "prime/run" setting (feeding
from main tank). Thirty minutes after it started we noticed that the
batteries were no longer charging and that the voltage coming off of
the generator was fluctuating between 80-120V. Once the generator was
switched over to the Aux tank the voltage was constant around 120V.


Xantrex Inverter/Dynasty Batteries:

Time Voltage (Temp Comp) Load Temp Generator Running?
1306 26.6V 7.6A 9C yes
1535 26.6V 9.5A 11C yes
1655 26.7V 16.8A 11C yes
2015 26.8V 6.6A 12C yes


Notes/Comments:
The high load at 1655 was due to running the water heater.

[**] Potable Water Meter Reading: 27472.9 gallons = 103995.9 L
[ +100.9 gallons since yesterday ]

Out to Toilet Meter Reading: 8359.2 gallons = 31642.9 L

We have a working grey water trickle system in the GreenHab!! Thanks
to Dan we found a brand new identical pump sitting in the upstairs
loft. We replaced the broken left pump in the GreenHab, keeping the
inlet filter (after a thourough cleaning). We replaced the screen
filter on the end of the inlet tube as well to insure that it will not
burn out this pump in the same way. Switching it on we got great flow
and opening the valve we started flow to AT1 (which in turn trickled
down to AT2, AT3, and filled an almost empty AT4). As a result we have
depleted most of the grey water stores under the hab. Consequently I
have mandated showers for all of the crew (we are all happy).

Also it seems that the bubbler that goes into AT2 and AT3 was not
working although it was receiving power. We switched the tubes to
another bubbler that was also hanging from the rafters which worked
very well.
