Minimum Pressure
Minimum Regulating Pressure Setting
Default = 10 PSI (0.7 bar)
This programming step allows you to set the minimum pressure that the sprayer control will regulate to.
Sometimes when the sprayer speed slows down, the control system will regulate the pressure so low that it falls
below the manufacturer’s recommended pressure for the spray tip or reduces system
fl
ow to the point where the
fl
ow meter will stall.
To avoid these situations, the TeeJet 844 can be programmed to not regulate below the pressure set in this step.
If this step is set for the default of 10 psi (0.7 bar), the pressure will not go below 10 psi (0.7 bar) while spraying in
automatic mode.
NOTE: Not all 844 models contain this programming step. If this step is not displayed, the 844 has an automatic
low pressure setting of 10 psi (i.e. the system will not regulate below 10 psi (0.7 bar).
When you have completed the Minimum Regulating Pressure Setting Step, you have completed the System
Setup Mode of the TeeJet 844 Sprayer Control.
NOW, PRESS AND HOLD THE
KEY FOR THREE SECONDS, AND THE ENTIRE PROGRAM SYSTEM WILL
BE STORED IN THE COMPUTER’S MEMORY.
NOTE: For your protection, the 844 console will not automatically power down while in the System Setup Mode.
You must exit properly, as described above, to enable the console auto power down feature.
NOTE: Cutting the power to the controller while in the System Setup Mode will not save any changes into the
computer’s memory.
