- 164: Radiometers, Site stn3, Mon 04-Mar-2002 11:29:04 MST, 4-component aspiration fans disconnected 3/2
4-Component FANS Disconnected: 3/2/02 ~16:30z
to reduce the power consumption.
The dome ventillator fans were pulling too much current
when the temperature was dropping too low.
There will probably be no measurable effect in doing
this because of minimal dust and ample winds in
North Park during this time of the year.
Note this was also entered in the 'station outage'
log entry.

Station 3 Power Outages
It appears Sage site is getting cold feet.....
---------------------------------
Sta3 - Sage Outage:
3/2/02 ~11:30 - 15:00z
Low voltage disconnect did it's thing.
Station recovered by itself with adequate solar charging,
no wind charging at the moment.
4-Component FANS Disconnected: ~16:30z
to reduce the load. They're still jumping up and down in
power consumption when the temp. drops too low.
---------------------------------
Sta3 - Sage Outage:
3/3/02 ~9:15 - 14:45z
Low voltage disconnect did it's thing again.
Station recovered by itself with adequate solar charging.
At about local noon, the winds picked up and the wind
generator was providing charging through the night.
- 161: Kryptons, Site stn3, Fri 01-Mar-2002 09:37:19 MST, Replace Kr at Sage
Inspected Sage site. All vent + asp fans OK
Kr #1133 was oriented with the receiver pointing to the S.
Kr 1133 was removed.
Kr 1395 was installed with receiver pointing to the N (wire S of attachment)
Had trouble sucuring the device but got screwws started and then used panduits.
- 142: Kryptons, Site stn3, Tue 19-Feb-2002 14:25:28 MST, new krypton
at sage, we just swapped 1133 for 1395 in hopes of solving the cold temperature
dropout problem
I also checked the fence battery which is now 14.5V connected through the
solar panel, so I think all is well.
I also note the serial numbers:
csat 538
trh 703
- 119: Soil, Site stn3, Thu 17-Jan-2002 17:46:48 MST, Trime at sage
Two readings were taken approximately 5 minutes apart.
1 - 7.6
2 - 8.2
- 115: Kryptons, Site stn3, Wed 16-Jan-2002 19:36:40 MST, Wrong cal used for krypton at sage site
Steve Oncley found the problem with the krypton at the sage site:
prep.config is using cal_files/krypton1392 for both s2 and s3.
s3 should have krypton1395. s3 has been going below 0 since
its voltage has been about 3.8 V and Vo for 1392 was 3.6V.
Vo for 1395 is 4.9V.
This has now been corrected, and the netcdf data for the sage h2o
variable are being re-computed from the present back to Dec 17,
when it was installed.
