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 loop of

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 console by joining its connector with the

connector on the short power cable lead that extends from the middle of the right

side of the console.

Test the installation by depressing 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, depress and hold the key while

depressing the key once, and then releasing both keys.The console

display will read “OFF” and will shut down after 5 seconds providing no

other keys are depressed.
