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 “+”
and “-” buttons to choose
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 on display. NOTE:
if using an old style Micro-
Trak servo valve, (See
Illustration below), set to 8 volts.

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
Ammonia (NH3).

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 low.

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 ball valves for boom shut-off, this
feature delays adjustment of the servo valve
until the boom valves are open. Use “+”
and “-” buttons to set from zero (OFF) to 4
seconds.
