INSTALLATION
CHAPTER 2 – INSTALLATION
MOUNTING THE TEEJET 845 CONSOLE
Console Step 1 - Location
Determine the best location for the control console in the cab or
operator’s compartment. Allow sufcient clearance, approximately
4 through 5″/10 through 12 cm to accommodate for the cable that
will be connected to the right side of the console.
Console Step 2 - Mounting
Mount the console to a rm support within the cab area, and
secure using the slots provided on the top, back, or bottom of the
Console. Although two simple brackets are supplied with the unit,
some additional bracketing may be necessary. The slots in the 845
will accept 1/4″ / 6 mm bolts.
Figure 2-1: Brackets Provide Angle Adjustment
Console Step 3 - Power Connection
Locate the power cable that 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: Make sure there are 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 845 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 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 to the blue 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 PROGRAM button once to
turn the 845 console on. If the display shows information, you have
wired the power correctly.
NOTE: The TeeJet 845 Sprayer Control has an Automatic Power
Down feature. With the Master Switch in the “OFF”
position, the 845 will automatically shut down after 10
minutes of no inputs or at the time specified in the Auto
Power Down setting in the OEM Setup Mode. This
prevents possible battery drainage. To turn the console
“OFF” with the Master Switch located in the “OFF” position,
press and hold the MINUS button while pressing the
PROGRAM button once, and then releasing both
buttons. The console will shut down providing no other
buttons are pressed.

INSTALLATION
Console Step 4 - Connecting Component Cables
Once the console is installed, connecting it to the other components of the 845 system can begin. The standard kit contains a main
cable that attaches to the master valve (optional), boom control valves, the pressure regulating valve, ow meter, and/or pressure
sensor, and a proximity speed sensor or radar speed sensor. Lay out each of the valve and sensor leads before installing the sprayer
components to be sure the cables are long enough in length from the sensor connections to the 845 console connection. If installation
requires longer cables, several extension cables are available. If an exit hole has to be cut in the cab, be sure the edges are deburred
and protected to prevent damage to the cables.

uses a 4-20 mA reading. “4.0 mA” represents “zero” pressure.
1. If necessary, run the Automatic Calibration to determine the
Zero Pressure Reference setting.
2. Enter the value for the Zero Pressure Reference setting.

Make sure that the sprayer pump is turned off and that there is
absolutely no pressure in the system (release pressure held by
boom control valves and Tip/Nozzle body check valves).
In some cases, it may be best to remove the sensor from the
plumbing system to complete the calibration.
1. Press and hold the PLUS and MINUS buttons
simultaneously for 3 seconds to start auto calibration mode.
The lower left portion of the display will count from 1 through 10
during the calibration.
Once the display nishes counting, it should display a number
close to 4.0 (+/- 0.2).
2. To accept the value, press the PROGRAM button. To edit
the value, use the PLUS button or MINUS buttons.

Maximum Pressure Rating
This step is only available if “Pressure Sensor Installed” is set to
“Yes”.
The Maximum Pressure Rating is used to establish the maximum
rating of the pressure Sensor in the system. This number can be
found stamped on the pressure sensor itself.
NOTES: Do not change the value to “0” even if there is no pressure
sensor installed. The Maximum Pressure cannot be set
lower than the Minimum Pressure. The Minimum Pressure
defaults to 10 psi / 0.6 bar, below this value regulation is
stopped.
Figure 3-10: Maximum Pressure Rating
Minimum Pressure
Below the Minimum Pressure value, regulation is stopped, except
when using lane spraying (GLM or LKM).

Select if a ow meter is installed.
If a pressure sensor is not installed this step is automatically set to
“Yes” and cannot be changed.
If lane spraying is selected under Units (GLM or LKM), this setting
will always be set to “Yes” and cannot be changed.

Flow Meter Calibration
This step is only available if “Flow Meter Installed” is set to “Yes”.
Flow Meter Calibration determines the ow meter Pulses based on
a known volume of uid.
1. If necessary, run the Automatic Calibration to determine the
number of pulses.
NOTE: The automatic calibration procedure is recommended for
maximum accuracy.
Or note the ow meter calibration number found on the factory
calibrated tag.
2. Enter the number of pulses.
Pressing the AUTO/MAN button will switch between normal
value and decimal value (/10). Decimal values can be used with
very low ow calibration values to improve regulation accuracy.

A volume of at least 50 gallons / 200 liters should be sprayed
during the calibration. The more volume used for calibration, the
more accurate the ow meter will be.
1. Press and hold the PLUS and MINUS buttons
simultaneously for 3 seconds to start automatic calibration
mode. This will clear the existing value and initiate the
calibration procedure.
2. Engage the sprayer pump.
3. Turn the boom sections on and begin spraying a predetermined
volume of uid (i.e., 100 gallons / 300 liters).
As the predetermined amount is sprayed, the console will count
the pulses.
4. After the predetermined volume has been sprayed, turn the
Master Switch off to stop counting pulses.
5. Press the PROGRAM button to advance to the next step.
6. Use the PLUS and MINUS buttons to enter the actual
volume sprayed (gallons / liters).
7. Press the PROGRAM button to exit Automatic Calibration.
8. To accept the value, press the PROGRAM button.
To edit the value, use the PLUS or MINUS buttons.
