PROGRAMMING THE 844 SPRAYER CONTROL SYSTEM

(

CONTINUED

)

USER PROGRAMMABLE TIP

Default = 0.00

1. While in the User Programmable Tip step, the

!

symbol will be flashing above the

P

tab at the bottom

of the display.

2. In some cases you may find that nozzles other than those preprogrammed for the 844 Sprayer Control

will need to be used. If one of the eleven pre-programmed tips do not meet your needs, this program-
ming step allows the user to program a tip.

3. Use the

or

key to adjust flow rate in Gallons Per Minute of a single spray tip at 40 psi. Depress-

ing the

and

keys simultaneously will clear the value to zero. To accept the value, depress the

key to advance to the next programming step.

If the user is using tips other than the TeeJet VisiFlo brand, the corresponding colors may

not match. In this case, the user should determine the flow rate of the tip being used a 40 psi,

and enter this flow rate as the programmable tip.

The flow rate will automatically be displayed at 40 psi. This pressure must be used for
determining your tip’s flow rate. Actual operation pressure is not important.

4. When the correct nozzle flow rate has been entered, advance to the next programming step by depress-

ing the

key.

PRESSURE REGULATING MODE

Default = byP (Bypass)

1. While in the Pressure Regulating Mode step, the

symbol will be flashing at the top of the console

display.

2. The default value “byP” indicates that the pressure regulating valve is plumbed in the bypass line. In

most situations, especially total flows below 4 GPM, this is the preferred installation position. If the

default is correct, depress the

key to accept the value and advance to the next programming step.

When programmed in the bypass mode, with the controller in “MAN” mode, the pres-

sure regulating valve should close when the

key is depressed, and open when the

key is depressed.

3. In large flow situations, the pressure regulating valve can be located in the supply line between the

flowmeter and the boom control valves. If you will be locating the pressure regulating valve in this posi-

tion, use the

or

keys to change the value to tHr (Throttle Mode).

When programmed in the throttling mode with the controller in “MAN” mode, the valve

should open when the

key is depressed and close when the

key is depressed.

4. When you have completed the programming for Pressure Regulating mode, depress the

key to

accept the valve and advance to the next programming step.
