GLOSSARY OF TERMS (From Ag Leader INSIGHT Manual)
Setting Name
Setting Description
Flow Meter Cal
Calibration valve representing the number of pulses that equal one-gallon of product flow through
the controlling system. See Note 1 Above.
Control Valve Configuration
Setting specifies the type of control valve being used for the rate control functions of the controlling
system. This must be set to “Inline Servo”.
Response Threshold
Determines where the control channel switches between using Valve Response 1 and Valve Response
2 setting.
Valve Response 1
Determines the speed of the servo valve when product control error exceeds the Response Threshold
setting. Valve Response 1 represents the fast speed of the servo valve.
Valve Response 2
Determines the speed of the servo valve when product control error is less than the Response Threshold setting. Valve Response 2 represents the slow speed of the servo valve.
Allowable Error
Determines the percent of error that is allowed prior to the product control system making any flow
rate changes.
NOTE: For additional glossary terms refer to your Ag Leader INSIGHT system manual.

The relationship between N and NH3 is as follows. One pound of
NH3 contains approximately 82% of actual N.
You can select either of these. If you are unsure, then just select
'N' (this is what Micro-Trak consoles use for target rate).

Liquifier Installation
PRE-INSTALLATION: Remove the Liquifier plumbing panel from
the shipping board. The Liquifier plumbing panel has been
packaged with the “strainer end” mounting bracket in a shipping
position. Before installing the unit on your applicator, move this
bracket to the other side (inlet side) of the strainer to allow access
to strainer clean-out plug for cleaning. After repositioning bracket,
make sure all three brackets rest on a flat surface. If necessary,
loosen all six carriage bolts (two per bracket) at base of brackets
to allow all brackets to rest flat on mounting surface of tool bar.
Tighten carriage bolts only after insuring that all three brackets rest
on bar and unit does not “teeter” on center bracket.
LIQUIFIER KIT INSTALLATION: Remove any existing metering
valves. If the old metering valve has a built-in manifold, it is
recommended to install a separate new manifold for the Liquifier
kit. Another option, although not recommended, is to use the
existing manifold, making certain the old metering valve is in the
maximum open position to allow for minimal restriction of flow
through the plumbing. There should not be any positive shut-off
valves installed in the plumbing between the Liquifier kit shut-off
valve and the knives.
Install the plumbing panel on the tool bar frame using the carriage
bolts and flange lock nuts through the top and bottom brackets of
the system. Trim any excess length off the bolts if required. Attach
the hose from the breakaway coupler to the strainer inlet. Check
SERVO VALVE
COUPLER
for proper hose length for operation of the disconnect mechanism
of the breakaway coupler. Connect the manifold hose to the servo
valve outlet. Check for proper hose length to avoid kinking at the
hinge points.
LIQUIFIER VAPOR TUBE INSTALLATION: Locate the 1/2” EVA
vapor hose supplied with the kit. Starting on one half of the tool
bar, connect the 1/2” hose to the outside steel vapor tube. Route
the hose up the shank and along the tool bar frame to the inside
steel vapor tube. Allow enough extra hose to avoid kinking at the
hinge points. Cut the hose to length and attach to inside steel
vapor tube. Install a 1/2” x 3/4” x 1/2” tee fitting approximately half
way along this hose between outside and inside steel vapor tubes.
SEE ILLUSTRATION ON PAGE 11.
Locate the 3/4” EVA hose supplied with the kit. Connect one end to
the 1/2” x 3/4” x 1/2” tee fittings and route along the tool bar frame
to the vapor outlet connections on the Liquifier. SEE ILLUSTRATION
BELOW. Allow enough extra hose to avoid kinking at hinge points.
Secure all hoses with properly sized hose clamps. Secure the hoses
to the tool bar frame with cable ties.
INSTALLATION NOTE: It is recommended to use an NH3
compatible thread sealing compound on all pipe thread
fittings.

NH3500 Kit Installation
Remove any existing metering valves. If the old metering valve
has a built-in manifold, it is recommended to install a separate
new manifold for the NH3500 kit. Another option, although not
recommended, is to use the existing manifold, making certain
the old metering valve is in the maximum open position to
allow for minimal restriction of flow through the plumbing.
There also should not be any positive shut-off valves installed
in the plumbing between the NH3500 kit shut-off valve and the
knives.
Locate a convenient area on the applicator to install the NH3500
plumbing panel. When selecting an installation location, keep in
mind that the hose from the break-away coupler must reach the
strainer inlet with enough length to allow for proper operation
of the break-away coupler disconnect mechanism and prevent
kinking of the hose at hinge points. Also, the strainer’s clean-out
plug should be accessible for regular cleaning. Make certain that
the area selected allows for enough length of the manifold hose,
between the manifold and the servo valve outlet, to prevent
kinking at hinge points.
INSTALLATION NOTE: It is recommended to use an NH3
compatible thread sealing compound such as “Slic-tite paste
with Teflon”, or a similar compound, on all pipe thread fittings.
Slic-tite is manufactured by LA-CO Industries, Inc./Markal
Company.
Remove the NH3500 plumbing panel from the shipping board.
Install the plumbing panel on the tool bar frame using the
bottom brackets, carriage bolts and flange lock nuts. Trim any
excess length off of the bolts if required. Attach the hose from
the break-away coupler to the strainer inlet. Check hose length
for proper operation of the break-away coupler disconnect
mechanism. Next, connect the manifold hose to the servo valve
outlet. Check for proper hose length to avoid kinking at hinge
points.

NH3500 Vapor Tube Installation
FOR ALL NH3 KITS
Locate the 1/2” EVA vapor hose supplied with the kit. Starting on
one half of the tool bar, connect the 1/2” hose to the outside steel
vapor tube. Route the hose up the shank and along the tool bar
frame to the inside steel vapor tube. Allow enough extra hose to
avoid kinking at hinge points. Cut the hose to length and attach
to the inside steel vapor tube. Install a 1/2” x 3/4” x 1/2” tee fitting
approximately halfway along this hose between the outside and
inside steel vapor tubes. See Illustration below. Repeat the same
procedure for the steel vapor tubes on the other half of the tool
bar. Secure all hoses with properly sized hose clamps. Secure the
hoses to the tool bar frame with cable ties.
Weld the steel vapor
tubes to the back of your
Ground Level
liquid tubes. All electronic
Vapor
Tubes
equipment,
including
the console and radar
speed sensor, MUST BE
Wear-resistant
DISCONNECTED BEFORE Surface
WELDING ON EqUIPMENT.
The four steel vapor tubes should be evenly spaced across
the applicator (two per side) and installed so that only
their wear resistant surface contacts the soil. Mount the
tubes just high enough to avoid plugging.
Locate the 3/4” EVA hose supplied with the kit. Connect to one
of the 1/2” x 3/4” x 1/2” tee fittings and route along the tool
bar frame to other 1/2” x 3/4” x 1/2” tee fitting. Cut to length
and install on the tee fitting. Allow enough extra hose to avoid
kinking at hinge points. Now install a 3/4” x 3/4” x 3/4” tee fitting
approximately halfway along this hose (center of the tool bar)
between the other two tee fittings. Using an appropriate length

on the NH3500 plumbing panel. Secure all hoses with properly
sized hose clamps. Secure the hoses to the tool bar frame with
cable ties.
“Working” Width
Your “working” width will be the number of knives times the
knife spacing in inches (meters). For example, if you have 8
knives spaced at 30 inches, the working width is 240 inches. See
Illustration below.

The NH3 adapter wiring harnesses are made specifically for use
on anhydrous ammonia applicators. The harness combines the
wires for the servo valve, flowmeter, shut-off valve and remote
access speed connector into a single 10-pin connector.

Field Operation - Troubleshooting for NH3
Field Operation:
Always follow accepted safety precautions. Make sure that
equipment is in good operating order. Before connecting the
nurse tank to the applicator, check the electric shut-off valve for
proper operation.
After changing nurse tanks or after other periods of long shutdown, operate the system in Manual Mode until the application
rate stabilizes. This allows the heat exchanger to reach operating
temperature before starting Automatic Operation. Erratic
operation may be experienced if Automatic Control is selected
is selected before operating temperature is reached.
Manifold pressure is very important for good distribution of NH3.
Use barbed fittings with properly sized orifices or an adjustable
manifold to maintain adequate pressure. If manifold back
pressure is too low, proper cooling will not be achieved, vapor
bubbles will be allowed to enter the flowmeter, and readings
will be inaccurate. Typical manifold pressure ranges from 15 to
60 PSI (1 to 4 bar) depending on application rates and ambient
temperature. If manifold pressure stops climbing but FLOW RATE
continues to climb, vapor bubbles are present.
In hilly or rough conditions the nurse tank dip tube will not
remain submerged, allowing extra vapor in the system. This
vapor is too much for the heat exchanger to condense and the
system will exhibit erratic operation. If the dip tube remains out
of liquid, operation may appear to be normal, but the system is
simply metering vapor. If this occurs, you will notice extremely
low manifold pressure. Change tanks before the NH3 level is low
enough to cause these problems.
In NH3 control systems, location of the frost build-up is an
indication of system performance. The NH3 kit will normally have
frost on the output side of the servo valve and in some cases, a
small amount on the bottom portion of the heat exchanger. Frost
before the servo valve indicates excessive pressure drop in the
delivery system or restricted vapor lines.
The strainer is a common source of excessive pressure drop and
should be cleaned regularly. AFTER COMPLETELY DRAINING THE
SYSTEM, remove the large plug and carefully clean the strainer’s
screen. Also, periodically check the vapor tubes for obstructions.

Flowmeter Assembly (FM-750 N)
IMPORTANT: Opening the flowmeter will void the Flow
Calibration value assigned to your unit. However, you may need
to take the flowmeter apart for periodic cleaning or to remove
an obstruction. See Illustration below for flowmeter reassembly
instructions.
absolutely necessary but will insure a good seal. Be careful not
to get compound inside flowmeter or turbine will stall. Carefully
put other flowmeter housing (sensor half) in place. (Position the
housing so that the two square lugs are lined up with each other.)
Drop all three bolts into holes. Hold lock washers in place and
finger tighten all three nuts. Nuts should be torqued to 120 in./lb.
(13.56 nw/m). Attach tag by running wire between a bolt and the
housings, and twisting.
TO OPEN THE FLOWMETER:
Disconnect the hose from servo valve to manifold. Loosen the
union hex closest to the heat exchanger. Remove the two “U”
bolts that hold the servo/flowmeter assembly to the brackets.
Unscrew the union from the heat exchanger and remove the
servo/flowmeter assembly.
After assembly, shaking flowmeter end-to-end should produce
a “rattling” sound (shaft end play). Blowing into the meter from
either end should cause the turbine to spin freely. If the turbine
only spins from one direction, install the flowmeter so that the
liquid flows in that direction.
Use running water to rinse the assembly of any accumulated dirt.
Remove the three flowmeter bolts, carefully open the flowmeter
and remove the turbine. Thoroughly clean turbine and housings
of any foreign material (dirt, pieces of teflon tape, rust on
magnets, etc.).
Start with original calibration number and follow procedure in
manual for verifying flowmeter accuracy.
WARNING
Set and spin the turbine in each flowmeter housing half. It should
spin freely. If not, remove the turbine, wipe the shaft and try
again.
TO PREVENT SERIOUS INJURY, DO THE FOLLOWING:
1. ALWAYS WEAR gloves, goggles, and other necessary
equipment when handling NH3 apparatus.
2. DO NOT cross thread. Use anti-seize lead base thread
compound.
3. THOROUGHLY BLEED hoses before disconnecting
NH3 apparatus.
4. COMPLETELY EVACUATE NH3 apparatus before
servicing.
TO ASSEMBLE THE FLOWMETER:
Place the servo, flowmeter end up, in a vice or other suitable
fixture. Set turbine in non-sensor housing. Properly position
gasket on housing. (Gasket may be reused a few times but will
eventually need to be replaced.) Pipe thread compound is not

IMPORTANT: Opening the flowmeter will void the Flow
Calibration value assigned to your unit. However, you may need
to take the flowmeter apart for periodic cleaning or to remove
an obstruction. See Illustration below for flowmeter reassembly
instructions.
TO REMOVE THE FLOWMETER:
Loosen two 1/2” bolts securing unit (shutoff valve end) to toolbar.
Loosen union between flowmeter and shutoff valve. Slide
shutoff valve away from flowmeter and unscrew flowmeter from
heat exchanger.
After assembly, shaking flowmeter end-to-end should produce
a “rattling” sound (shaft end play). Blowing into the meter from
either end should cause the turbine to spin freely. If the turbine
only spins from one direction, install the flowmeter so that liquid
flows that direction.
If turbine does not spin freely, flowmeter may require repair.
Turbines and bearing replacement kits are available.
TO DISASSEMBLE THE FLOWMETER:
Before reconnecting the union, loosen all six 3/8” carriage bolts
at bottom of mounting bracket uprights. Tighten union then
re-tighten 3/8” carriage bolts. This ensures that unit sits flat on
tool bar and does not “teeter” on center bracket.
Remove retainer clip from one end and slide out internals. See
Illustration below. Be careful not to bend turbine shaft.
Start with original calibration number and follow procedure in
manual for verifying flowmeter accuracy.
Clean and inspect parts.
Assemble in reverse order.
