SubStation: How to Test devices

Updated August 21, 2025 1 min read

When you test a zone, the controller verifies the communication between the controller and the 
valve biCoder. The controller activates the solenoid and measures the current and voltage. It 
deactivates the solenoid, and measures the voltage drop between the controller and the valve 
biCoder.

  1. Press the Test button. The Test menu displays.
  2. If the Test Zone option is highlighted, press the OK button to select it. If Test Zone is not 
    highlighted, press the up or down button to highlight it, and then press the OK button. The Test 
    Zone screen displays.
  3. Press the up or down button to select the zone number that you want to test.
  4. Press the OK button to test the zone.
    1. The valve will activate for less than a second 
      to measure the voltage and current through 
      the valve solenoid. This test will return the 
      status of the valve, the biCoder serial 
      number, the solenoid current, the solenoid 
      voltage, the two-wire voltage drop, and the 
      version of the two-wire device. If any zones 
      or programs are running when the test is activated, watering will pause for 10 seconds. 
  5. Repeat steps 3 and 4 until you have tested all the zones that you wish to test.
  6. When you have finished viewing the test results, press the RUN button to return to the Run 
    menu.
