PCDL-1000: All Zero Counts

Last Updated: 2/3/2010 4:07:19 PM

Symptom
After downloading data from the PCDL-1000 Count Recorder, all counts read as zeros.
 
Cause
    Possible
  • Improper Wiring
  • Bad Connections
  • Output Problem on Sensor/Controller
  • Defective Count Recorder
    • Refer to Resolution steps to rule out a defective Count Recorder
 
Resolution
Note: A small piece of wire, or a paper clip, is needed to test the Count Recorder by completing the circuit between the two pins on the PCDL-1000's green (phoenix) connector. (Manipulate the wire/paper clip to form a horseshoe shape - refer to Figure 1.)
  1. Connect the Count Recorder to the computer
    • The Counter Recorder software must be installed on this computer.
  2. Navigate to Start Menu » All Programs » SenSource 7.00.XX (folder) » SenSource 7.00.XX
    • Where XX is the current build
  3. Select Device on the top navigation menu and then scroll down to select Real Time Chart Recording.
  4. Click to view the Data tab.
  5. Set the Reading Rate to 5 seconds from the dropdown menu.
  6. Click the Start Recording button
  7. Use the wire, or paper clip, to bridge the connector pins on the Count Recorder (refer to Figure 1).
  8. If the Count Recorder is functioning properly, each connection with the wire/paper clip will display as an integer in the Counts column of the Data tab.
    • If no counts are displaying for each 5-second pulse, the Count Recorder is likely in need of repair or replacement.
    • If counts are displaying, the Count Recorder is functioning properly.
      • Verify that all sensor/controller wiring is correct and that all connections are good/tight.
  9. When finished testing the Count Recorder, click Stop Recording.
  10. Exit the Real Time Chart Recording by clicking the Done Recording button.
