Station Servicing


These documents can help guide you through various aspects of Station Servicing, including Time required, Crew needs, Recordkeeping considerations, and Suggested Materials.


A servicing team should consist of a minimum of 2 people for safety concerns. 

Station servicing time should average approximately 30 to 45 minutes with no repairs needed on the station.

Below is an example of a station Service Sheet. Please have PASSCAL review the Service Sheets (and Install Sheets) you plan on using for your experiment, even if you downloaded them from the PASSCAL website. We tailor the Sheets to your experiment, specifically the equipment you've borrowed. Plus datalogger firmware changes, newly discovered bugs, etc. necessitate revisions to these Sheets. Thank you.

    * NOTE  Either Disk 1 OR Disk 2 is (Current) and should be a non-zero value.
     Whichever disk is NOT Current must be zero  (formatted and ready for data after the first Disk (1 or 2) is full)
15. Check Disk Setup (Control ==>Disk):
  If telemetered:  Auto-wrap  Yes
  If stand-alone:  Auto-wrap  No
16.  Write .CFG File to Disk (Control==>Status==>DAS LP/WP)
 Tap the WRITE button to write the .cfg file to the disk.
 Verify that the value of disk space used increases (Control ==>Status).

Make sure all plugs and connections have been replaced.

POWER: Check Power ONLY IF the station has Power Problems
NOTE: The following tests should be performed with the solar panels in full sun. Check solar panel is clean.
1. Disconnect the solar panel.
2. Test output of the batteries (12.5 - 13 Volts DC
WARNING: DO NOT test the current of the battery)
3. Test the voltage out of the power box to the DAS from pin A+ to C-. (Same as battery voltage measured above).
Make sure the polarity is correct

4. Test the solar panel output (18 Volts DC)
7. Connect the solar panels to power box
8. Test the voltage at the battery terminals (Greater than the battery voltage measured above).
