Engineering Report

Eric Harkleroad Reporting


Generator/Electricity:

Wendy

Hobbs Meter: 3579.1 hrs [ +22.6 hrs since yesterday ]

Voltage: 120 VAC

Frequency: 60 Hz

Oil Level: full

Oil Pressure: 30 PSI

Water Drained: yes


Notes/Comments:
Added an additional quart of oil to Wendy today.

Reset circuit breaker on backup diesel generator DP7500DE today--will
attempt to run on this generator once more before our crew leaves. Per
Mission Support request, here are the codes found on the connectors:

->20A (1st on left): L5-30,B-015
->30A 4-prong (4th from left): L14-30,YGB-035


Xantrex Inverter/Dynasty Batteries:

Time Voltage (Temp Comp) Load Temp Generator Running?
11:29 26.8 8A 8C yes
13:50 19.7 8.5A 8C no
14:10 26.4 6A 8C yes
18:08 24.7 16A 11C yes
19:45 25.5 16A 11C yes



Fuel Status (as of 21:34):

Diesel:

Approximate Reading: 5/8




Propane Tank:

Approximate Reading: 69% (690 gallons = 2611.9 L)




Gasoline:

Quantity Remaining: 45 gallons = 170.3 L [ -2 gallons since yesterday ]


Notes/Comments:
We understand Don's fix for the gasoline dispenser was to remove a flow
restriction device intended as a safety feature (seems like this
feature is more relevant for cases where flow is assisted by a
mechanical pump, which we do not have).



Oil:

[*] GenSet Quantity: 16 quarts [ -1 quarts since yesterday ]

[*] ATV Quantity: 13 quarts [ no change since yesterday ]

[*] V'ger Quantity: 0 quarts [ no change since yesterday ]



Water Status:

Outside Potable Water Tank Level: 340 gallons = 1287.0 L

Trailer Potable Water Tank Level: 1 inches from the base

Potable Water Meter Reading: 26854 gallons = 101653.1 L
[ +68 gallons since yesterday ]

Out to Toilet Meter Reading: 8260.3 gallons = 31268.5 L
[ +8.3 gallons since yesterday ]

In to GreenHab Meter Reading: 7823 gallons = 29613.2 L
[ no change since yesterday ]

Dishwasher Runs: 0


Notes/Comments:
HSO and Assistant HSO cleaned the internal water tank with bleach today
and removed accumulated dirt.


GreenHab:

Crops Watered: no


Crop Condition:
Looks OK.


Observatory:

not used


Transportation:




Kawasaki ATVs

ATV 1
Used: yes
Oil Checked: yes
Fuel Consumed: 1 gallon = 3.8 L
Tire Status: OK

ATV 2
Used: no
Oil Checked: no
[*] Tire Status: NO VALUE SUPPLIED

ATV 3
Used: yes
Oil Checked: yes
Fuel Consumed: 1 gallon = 3.8 L
Tire Status: OK



Appliances:
Built the official C68 toilet bowl cleaner using spare PVC pipe--we
intend to leave the facilities sparkling for C69 :)


GreenHab:
Grey water was pumped into the GreenHab tanks this morning until full as
usual.

Crew 69 may need resupply of gloves for the GreenHab (previously
discussed in emails with Mission Support).

Thermostat controlling the propane heaters is located on the partition
between the two halves of the GreenHab building (to the left of the curtain and
at eye level when facing toward the grey water room and away from the
plant room). Thermostat appears to be programmed to keep the
temperature above 40F (no settings altered by this crew)--not
completely certain of the settings.

Aquatic tank #2 is showing more air bubbles than usual at the surface.
Not sure what this means or if it is cause for concern.

We had to agitate the float sensor in the toilet supply tank today
(TST=black tank on shelf above aquatic tank #4) since the tank was not
refilling and the low level prevented flushing. This fixed the problem,
causing the tank to refill and allowing flushing again.

Upgrade Work:
Currently working on a PVC & wood test tube rack (a distant cousin of
the official C68 toilet bowl cleaner) to facilitate studies in the lab.
