functions. With a quick glance, the display

reveals the application rate (automatically

switches between target and actual),

pressure, speed, and area covered.

Individual Boom Controls

give independent control of up to ve boom sections,

allowing better management of varying eld features

like waterways and terraces.

Color-Coded Tip Selection Bar

allows for easy user programming by

matching the color of TeeJet VisiFlo®

spray tips.

Easily Accessible

application option for fail-

safe reliability.

Master Shuto

controls all boom sections

with one switch.

• Full-featured sprayer control with industry-leading ease of use

• Large back-lit display shows all spraying information at a glance

• Color-coded tip selection for easy programming

• Communication Port for PC and GPS interfacing

• Flow or pressure based regulation options provide reliability and exibility

CHAPTER 2  MOUNTING SPRAYER COMPONENTS

Pressure Regulator in Bypass Mode

All pressure regulating valves for the 844 will be wired for use in a by-

pass system. While plumbed in a by-pass mode, with the Auto/Manual

key in the “MAN” mode, the valve should close when the Plus key is

pressed and open when the Minus key is pressed.

The pressure regulating valve can also be mounted in a throttling

situation as an alternative location. Refer to pages 3 and 4, and Figures

3 and 4.

NOTE: The diagrams in Figures 1 and 2 are shown as general

guidelines to follow when plumbing the 844 components. The

type of pump used and location of other components can

vary from sprayer to sprayer. It is important to ensure that if a

pressure transducer is used, it is located as close to the spray

tips as possible. Normally, this is at the boom control valves.

However, if one particular boom section is always used, the

pressure transducer can be mounted on that particular boom

section. If a flow meter is used, make sure that all of the flow

going through the flow meter is directed to the spray tips. Make

sure that proper distance is allowed on the inlet and outlet side

of the flow meter (refer to Figures 2 and 3).

Figure 1: Bypass Plumbing Diagram - Pressure Based System

98-70006-ENUS R4

844-E Sprayer Control

Figure 2: Bypass Plumbing Diagram - Flow Based System

Pressure Regulator in Throttling Mode

The pressure regulating valve, as shown in the gures below, can be located in the supply line before the boom control valves. If you choose this

location, the 844 will need to be properly programmed to reverse the polarity of the valve. This step can be found in the System Setup instructions

on page 14. When in throttling mode, the valve should open when the Plus key is pressed, and close when the Minus key is pressed. Be

sure to check this before plumbing the valve into the system.

844-E Sprayer Control

Figure 4: Throttling Plumbing Diagram - Pressure Based System

Flow Meter

To ensure accurate readings, the ow meter (if used) must be mounted

10″ to 12″ (25-35 cm) from other pipe ttings, preferably in a vertical

position with the ow going up. It should also be mounted with the

direction of ow arrow pointing toward the boom control valves. Refer to

Figures 2 and 3.

Be sure the ow meter is plumbed so that all liquid passing through it

is routed to the booms and not back to the tank. When using three-way

boom control valves, refer to page 13 of this manual for programming

guidelines.

Boom Control Valves

The Boom Control Valves are connected in tandem and centered in

front of the boom sections. See the Control Valve Instruction Manual for

mounting instructions. If using three-way valves, refer to the instruction

manual of the valves you are using for valve calibration instructions.

Pressure Transducer

The pressure transducer (if used) should be installed as close to

the spray tips as possible. Normally this is at the boom control valve

assembly. Refer to Figures 1 through 3. Mount the unit vertically on a

short stand pipe to help protect the sensor.

NOTE: Pressure drop, to some degree, is found in most plumbing

systems. Pressure drop is created when there is any kind of

restriction in the spray line that reduces flow rate and is quite

often produced between the boom control valve assembly and

the spray tips. If one of the boom sections on the sprayer is

always used, the pressure transducer can be installed on that

particular boom section, minimizing any potential pressure drops

between the sensor and spray tips. If the pressure drop in your

system is greater than 5 psi (0.3 bar), you should consider this

as an alternative location for the pressure transducer.

Check all components to make sure they are mounted securely to avoid

excessive vibration.

INSTALLING THE SPEED SENSOR ASSEMBLY

Components

Two (2) magnets, Sensor with attached connector cable, and mounting

hardware. If you are installing a radar ground speed sensor, follow the

instructions supplied with that unit.

Speed Step 1 - Location

The speed sensor assembly should be installed on a non-driven wheel

to avoid potential errors that are likely to occur from a slipping drive

wheel. Refer to Figure 5.

Proximity Sensor (optional)

An optional proximity sensor is available to use in cases where space

is limited or for drive shaft mounting.

The proximity sensor will work by sensing any metal object. The

proximity sensor must be mounted so that the sensor face is within 1/8″

to 3/8″ (3-10 mm) of the metal object being read.

Speed Step 2 - Installing The Wheel Magnets

Check for pre-drilled holes in the wheel rim. If pre-drilled holes are not

available, layout a pattern as shown in Figure 7 and drill two 3/8″ (10

mm) holes near the outer edge of the rim if possible, and 180° from

each other.

Place the magnets into each of the two holes on the inside rim and

securely fasten them using the nuts and washers provided.

Speed Step 3 - Installing the Magnetic

Sensor

The at, pressed L bracket of the wheel speed sensor kit should be

secured to a vertical member near the non-driven wheel. The round,

right angle steel bracket is then secured to the at bracket with the

two U-bolts and necessary hardware provided. The round, right angle

bracket is then used to secure the magnetic sensor mounting clamp.

The magnetic sensor should be inserted into the mounting clamp and

positioned within 1/8″ to 3/8″ (3-10 mm) of the wheel magnet. Tighten

the sensor clamp using the clamp screw per Figure 10.

Your installation will likely vary from the example. It may be necessary

to customize the installation to accommodate your specic machine.

Keep in mind that the two magnets must be spaced an equal distance

around the wheel. The magnetic sensor must be mounted in-line with

the magnets and positioned within 1/8″ to 3/8″ (3-10 mm) from each

magnet as they pass the Sensor assembly.
