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 level
where the Warning LED
star
ts 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 le
vel is low.
Auto Shut
off 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
