Why do the application rate units flash on my TeeJet Controller?
The application rate units might be flashing because there's a continuous discrepancy of 10% or more between the target and actual application rate. To resolve this, check all components and programming steps related to flow.
What to do if the pump capacity is too low on my TeeJet Controller?
If the pump capacity is too low, verify the pump is working correctly. Also, inspect the plumbing system for any obstructions and consider reducing the agitation volume.
Why is the pump capacity too high on my TeeJet Controller?
Some centrifugal pumps provide more flow than necessary for the application. A throttle valve may be required to restrict the flow coming from a centrifugal pump.
How to fix no speed sensing on my TeeJet Controller?
Check the speed sensor to ensure it is sending pulses to the controller.
What to do if the tips are plugged on my TeeJet Controller?
If you have plugged nozzles, remove them from the boom and clean them with water and a TeeJet brush.
What to do if the flow meter is stalled on my TeeJet Controller?
Make sure there is no pressure in the system. Remove the flow meter from the discharge line and inspect the inside of the meter for obstructions. The turbine should move freely; if not, try flushing it out with clean water.
How to correct a flow meter plumbed incorrectly in TeeJet Controller?
A flow directional arrow is located on the body of the flow meter. Plumb the flow meter with the arrow in the direction of the flow.
What causes extreme low regulated flow on my TeeJet Controller and how to fix it?
Extreme low regulated flow can occur due to very low application rates, causing the regulating valve in throttling mode to operate in an almost closed position. Adjust the Reg. Valve Speed Number in the System Setup Mode to a slower value.
How to troubleshoot regulating valve malfunction on TeeJet Controller?
Check wiring from controller to the regulating valve.
