TeeJet 844-AB - Simulated Ground Speed Operation

844-AB Sprayer control 13
Software 4.03
Simulated Ground Speed
Simulated ground speed allows the console
and sprayer to be tested (and actually spray
water) without physically moving the sprayer.
This can and should be tested prior to any
spraying activity.
The 844-AB has a low and high simulated
ground speed. This allows the operator to
switch between the two to simulate a speed
change and ensure the console is regulating
properly during the sprayer checkout.

To enter simulated speeds, determine
whether the low or high simulated speed is
displayed on the console. Change from low to
high by pressing the Auto/ Man key. Use the
Plus or Minus keys to adjust the values. Press
the Auto/Man key to switch to the other setting
(either low or high) and adjust the value with
the Plus or Minus keys. Once both values are
entered, press the Program key to advance to
the next step.
The console will display the simulated speed
upon exiting System Setup mode. The
simulated speed will remain on the Operation
mode display until the console receives actual
speed pulses. While in Operation mode, with
the Master Switch in the “On” position, press
the Program and Minus keys for low simulated
speed; press the Program and Plus keys for
high simulated speed.
NOTE:
The simulated speed feature will be
deactivated once the sprayer begins
moving and the 844-AB receives actual
speed pulses. If a radar speed sensor is
being used, disconnect the radar
connection from the main console. Any
movement can disable the simulated
speed test due to the sensitivity of the
speed sensor.
