Power Connection
Locate the power cable which has a black connector on one end, and two battery
terminal rings on the other. Extend the battery terminal ring end of this cable from
the cab to the battery.
Note: Some tractors use two 6 Volt batteries as a power source. Make sure
there is a total of 12 Volts delivered to the controller by connecting to the
(+) terminal on one battery and the (-) terminal on the other battery.
Reliable operation of the 844 Sprayer Control depends on a clean power
supply. Ensure this by connecting the power cables directly to the battery
and not to another power source.
Connect the battery terminal rings to the battery posts, making sure that the
positive
(red) and negative (black) wires correspond with the polarity of the
battery terminals.
Note: The power cable is designed to provide the simple addition of a remote
master boom switch in a convenient location (i.e. on the throttle, gear shift, or
floor switch). To install a remote boom switch, simply install a switch in the brown
wire in the power cable.The switch should be rated to handle the total current
used by all boom section valves combined. If installed, the remote master switch
will operate in series with the boom switches on the console.
Connect the battery cable to the power cable lead that extends from the main cable.
Test the installation by pressing the key once to turn the 844 console on.
If the display shows information, you have wired the power correctly.
Note:The TeeJet 844 Sprayer Control has an automatic power down
feature. With the master boom switch in the “off” position, the 844 will
automatically shut down after 10 minutes of no inputs.This prevents
possible battery drainage.To turn the console “off” with the Master Switch
located in the “off” position, press and hold the key while pressing
the key once, and then releasing both keys.The console will shut down
providing no other keys are pressed.
