Units:
Choose the system of units desired. Turf units are
the same as English units except Area is in thousands of
square feet. use the “+”

between EnG (American
English units), MEt (Metric)
and TurF (Turf units).

Valve Voltage:
Selects the operating voltage for the servo
valve. Factory setting is 12 volts. use the “+” and “-” buttons
to toggle between 8 and 12

Material:
use “+” and “-” buttons to select between liquid
(H2O displayed) or anhydrous ammonia (nH3 displayed). If
in NH3 mode, rates will be displayed in pounds (kg) actual N
and totals will be displayed
in pounds (kg) anhydrous
ammonia (NH3). NOTE:
if NH3 is selected
, see
appendix F
for NH3 specific
instructions.

Valve Response speed:
Allows adjustment of response
to “tune” the system for use with very fast or slow valves.
For example, if using a ball valve that takes several seconds
to open or close in manual mode, and the system responds
sluggishly, use the “+” button
to adjust the valve response
number to 1, 2, or 3. The range
of adjustment is -4 to 3, factory
setting is -1.
NOTE: exercise
caution when increasing the
valve response speed. If using
a relatively fast valve (1-3
seconds open-to-close), the system may become unstable
with higher valve response speed numbers entered.

Fill Tank size:
If using the Tank feature, this setting can
be used to enter the volume of the tank. use the “+” and
“-” buttons to choose OFF or any value from 1-65,535. Then
when the tank is filled,
the tank counter can be
reset to full by simply
turning the rotary switch
to the TANK position
and pressing the “+”
button. Depending on
the “uNITS” setting, the
TANK SIZE units will be either gallons or liters. If “material”
is set to NH3, the Tank Size will be in lbs. or kg. Anhydrous

Tank Alarm set point:
use the “+” and “-” buttons to
set the desired value. This value sets the level at which the
Warning LED starts flashing and the word “FiLL” flashes on
the display. Range is OFF or 1-65,535. When the tank value
drops below the set point,
the alarms will notify the
user that the tank level is

Auto shutoff ON/OFF:
When Auto Shutoff is enabled (On)
the servo will run toward minimum flow for 4 seconds any
time the system is put in
HOlD or all booms are
turned off, or if in AuTO
mode and speed goes
to zero. This feature is
normally used only in Dry
Application systems where the HOlD condition must stop a
hydraulic auger or conveyor belt.

Auto delay Time:
Typically used when using relatively slow

seconds.
