Operating Instructions
THE SPRAYING OPERATION
Fill the sprayer tank and thoroughly mix the chemical(s). Your application rate should be
determined as well as the spray tip you will be using, with the sprayer data programmed into
the computer.
Switch the computer on by pressing the key on the display panel.
While spraying with the Master switch “ON”, you can scroll through the different displays
using the key until the information you want is on the display :
♦ actual application rate in GPT or GPA
♦ vehicle speed in MPH or shaft RPM
♦ pressure in PSI
Adjust the target application rate with the + and
Switch the Master boom switch to “ON” position to start spraying. Maintain your usual vehicle
speed for spraying. Use the + or keys to boost the application rate if needed. Small
changes in vehicle speed are compensated by the automatic rate controller while spraying in
Auto mode. Manual mode allows the operator to manually adjust system pressure by using
the + and
If for any reason you need to stop, turn the MASTER BOOM SWITCH to “OFF.”

keys.
Automatic Power Down
The TeeJet 834-P Sprayer Monitor has an automatic power down feature. With the Master
switch in the “OFF” position, the Console will automatically shut down after 10 minutes of no
inputs (when in normal working mode). This prevents possible battery drainage. Note that the
console will not power down while in programming mode.
You can also power down the controller by the following key combination: press
simultaneously the Auto and
with the Master switch OFF).
keys and the Console will power down immediately (only
Warning: Do not switch off the console by removing the main cable!

Alarms and Warnings
On the 834-P Console there are three LED's for indication of alarms or warnings.
• The Speed alarm LED flashes when no speed pulses are
received during spraying (Master in the ON position). This
indicates that there is something wrong with the speed sensor
or that you are standing still while spraying.
Note: When this alarm is triggered, the display will
automatically switch the application display to view
speed (if not currently viewing speed) and the speed
display will flash off and on as well. This allows the
operator to immediately determine the location of the
problem.
• The Pressure alarm LED flashes when the signal from the
pressure sensor is absent while spraying (Master in
the ON position). This indicates that the pressure sensor is
not working properly, or that the connection with the sensor
has been lost.
Note: When this alarm is triggered, the display will
automatically switch the application display to view
pressure (if not currently viewing pressure) and
the pressure display will flash off and on as well.
This allows the operator to immediately determine
the location of the problem.
• The minimum RPM/MPH LED is lit when the programmed
minimum speed or RPM has been reached. When this LED is lit,
the pump has been switched off.

Programming Guidelines
Make sure that all hardware components are properly installed and tested. Before you start
the programming process you should first check if the console and all sensors are working
properly.
Important Preliminary Information
Before you begin, we recommend that you review the following Programming Guidelines that
control the programming process:
The key is used to power the console ON
Auto & simultaneous key combination is used to power OFF (Master boom switch
must be in the off position)
Holding key for 3 seconds is used to enter programming mode
The white text above the indicator LEDs on the front panel refers the the data displayed
in normal working mode. Look at the white colored text labels whil in normal operating
mode.
The gold text below the indicator LEDs on the front panel refers to the value being set in
programming mode. Look at the gold colored text labels while in programming mode.
Pressing the key saves the current parameter and advances to the next
programming step during programming mode
The value of a parameter is changed with the + and keys. Holding the + or
key changes the parameter rapidly.

Console Programming (GPT Mode)
To begin the programming process:
Be sure the Master boom switch is “OFF.”
Turn console “ON” by pressing the key. When the control console is turned on, the
software version will be displayed for approximately 5 seconds. At the same time all
LED’s will be ON.
The software version and serial number of the console will be needed when calling for
support. The serial number is located on a sticker on the back of the console.

System Setup Mode (GPT mode)
The System Setup Mode contains the programming steps that customize the controller to the
sprayer or sprayer components. These include calibration steps and parameters that, once
programmed, are not likely to change.
To enter the System Setup Mode:
First be sure that the console is ON (if not turn it on by pressing the key and wait
until the normal display is visible).
Ensure the Master boom switch is OFF.
Then press and hold the key for 3 seconds to enter the Program Mode.
OPERATING MODE
The 834-P can operate in either of two modes. They
are GPT (gallons per ton), used for pre-wetting
applications, or GPA (gallons per acre)used for
agricultural or anti-icing applications.
Use the + or
keys to adjust this value. Once
the correct mode has been selected, press
the key to advance to the next step. If
operating in GPA mode, skip ahead to page 14.
MINIMUM RPM
The 834-P can be set to automatically switch off the
flow of liquid when the salt/sand auger shaft slows
below a minimum speed. This feature prevents
liquid from being applied when the salt/sand
spreader is switched off.

revolution. For example, if the shaft speed sensor is mounted to sense the teeth of a
sprocket, enter the number of teeth on that sprocket.

POUNDS PER ROTATION
In order to apply liquid at a fixed proporation to the dry material being applied, the controller
must be able to associate the amount of dry material applied with each rotation of the shaft.
To determine this number, operate the dry spreader. Allow the shaft to turn several
revolutions and weight the material applied. Divide the total weight by the number of shaft
rotations to determine pounds per rotation (lbs/rot).

This value can be determined by an automatic calibration sequence. To perform this
operation:

SPEED SENSOR CALIBRATION
Default = 250 pulses/300ft
The speed sensor needs to be calibrated in order to
provide the proper speed reading. The value for this
step is the number of pulses generated by the speed
sensor in 300 feet. For example, if the speed sensor
is mounted to sense lug bolts on a sprayer wheel,
this value would reflect the number of bolts passing
the sensor over a 300 foot distance.

The speed sensor can be automatically calibrated
by driving 300 feet. The console will automatically
detect a RADAR sensor (if used).
To start the auto calibration procedure, press
