Veris U3 Operating Instructions Manual page 18

The pH Cycle State indicator will alert the operator to the current state of the pH sequence. In addition, the
indicator lights on the screen will show the state of the controller input and outputs. The information
provided in these steps is for reference only, once the conditions for starting the pH cycle have been met,
the following sequence will automatically take place.
1) Rinse electrodes for 1 second. This clears any dust that has built up on the electrode while
traversing the field. When in automatic mode, the software anticipates a slowdown, and will
automatically pre-rinse the electrodes.
2) Send down command to hydraulic cylinder
3) Wait until down proximity sensor is enabled, then disengage hydraulic cylinder
4) Record sensor data (subject to settle method)
5) Cycle Up
6) Wait until Up proximity sensor is enabled, then disengage hydraulic cylinder
7) Wash Electrodes
