Log Book for March 25, 2008
Engineering Report
Elisha Sanders Reporting
Generator/Electricity:
Wendy
Hobbs Meter: 3881.1 hrs [ +22.5 hrs since yesterday ]
Voltage: 120 VAC
Frequency: 61 Hz
Oil Level: 3/8
Oil Pressure: 30 PSI
[*] Water Drained: no
Notes/Comments: While pumping water to the inside tank the flow stopped midway through. Checking the generator the frequency gauge was wildly bouncing around. During this time the water would not flow. After turning it off and restarting the generator the frequency finally settled down and flow resumed. During all of the fluctuations the inverter never indicated a problem in the power coming from the generator. Also the flow would stop while the microwave was running (total load: 17.5A).
Xantrex Inverter/Dynasty Batteries:
Time Voltage (Temp Comp) Load Temp Generator Running? 1450 26.7V 7.6A 21C yes 1455 26.3V 8.4A 21C no 1959 26.7V 8.0A 21C yes
Fuel Status (as of 20:09):
Diesel:
Approximate Reading: 3/8
Propane Tank:
Approximate Reading: 56% (560 gallons = 2119.8 L)
Gasoline:
Quantity Remaining: 36 gallons = 136.3 L [ -1 gallons since yesterday ]
Oil:
[*] GenSet Quantity: 15 quarts [ no change since yesterday ]
ATV Quantity: 8 quarts [ no change since yesterday ]
[*] V'ger Quantity: 0 quarts [ no change since yesterday ]
Water Status:
Outside Potable Water Tank Level: 310 gallons = 1173.5 L
Trailer Potable Water Tank Level: 20 inches from the base
Potable Water Meter Reading: 27610.7 gallons = 104517.5 L [ +45.1 gallons since yesterday ]
Out to Toilet Meter Reading: 8392.0 gallons = 31767.1 L [ +11 gallons since yesterday ]
In to GreenHab Meter Reading: 7829 gallons = 29635.9 L [ no change since yesterday ]
Dishwasher Runs: 0
GreenHab:
Crops Watered: yes
Crop Condition: Lettuce is wilting, corn browning at edges. Cilantro turning red, dill yellowing, radish leaves turning brown. Overall things look to be uniformly drying out. We have totally turned off both heaters on each side (internal temp in the low 100s). We are going to water as needed everyday until crop condition stabilizes.
