Troubleshooting
pH and EC Probe Troubleshooting
1. I am not getting a reading when calibrating the pH sensor.
2. Measured values are not coming in correctly, the units are wrong.
3. The readings between the two redundant sensors is off by more than the tolerance set point. (Example: pH Sensor 1 is reading 5.95 and Sensor 2 is reading 6.45.)
Nutrient Dosing Pump Troubleshooting
1. A dosing pump is not pumping a nutrient.
2. A nutrient is settling or separating while sitting in the tank and doesn’t pump evenly over time.
3. EC / PPMs are consistently coming in too low during recipe preparation.
4. There are air bubbles in my dosing lines.
Irrigation Pumps Troubleshooting
1. The irrigation pumps won’t deliver my mix.
2. Foreign particles have entered the machine through the fresh water input and clogged the system.
3. Why is a different volume of water being delivered to feeding zones in one of my rooms? (i.e. Zone 1 gets more volume than Zone 4)
4. A plumbing fitting has cracked or broken.
Software Troubleshooting
1. Overshooting pH Up/Down on low EC recipes, resulting in too many pH attempts and the system timing out
2. Recipes are not coming in at the established EC setpoint and the AFS requires multiple EC adjustment attempts prior to signing off on the batch.
4. The VNC remote access software is discolored or buggy looking.
5. My flow rate is too high/too low.
6. I have discovered a software bug.
7. My system is lagging.
8. I don't see a cursor on my VNC remote access app.
9. I am pressing buttons on the software but nothing happens.
10. The liquid in the tank icon on the software is bouncing around; volume doesn't appear accurate.
11. I scheduled a flush day but it did not feed as scheduled.
