2
PRE-INSTALLATION
It is important that the installer is familiar with the equipment
interconnection cabling prior to installation. The installer should
refer to the additional paragraphs in this chapter for system and
interconnecting diagrams.
This section deals with the following topics:
•
Cable route planning
•
Environmental considerations

The reason for installing the flow turbine unit before the flow
control valve is to avoid minimum turbulence around the flow
turbine unit. If for physical installation reasons the IntelliFlow
turbine and IntelliFlow motor valve can not be installed according
7
to upper diagram, units can be inverted. It is recommended to
maintain a ratio of 10 to 1 of hose ID going into the flow turbine
and a ratio of 5 to 1 of hose ID between the turbine and IntelliFlow
motor valve. The reason for this separation is to ensure that the
turbulence does not affect flow control parameters.

INSTALLATION GUIDELINES
INTELLIFLOW UNIT
FOR
Install the flow meter in the down flow position, aft of the
IntelliFlow regulating valve when possible.
It is important to maintain a reasonable distance between the
aircraft regulating bypass the valve and the flow turbine meter;
when possible, no less than 8 inches.
It is best to install one or two support fittings from the belly of the
aircraft close to the valve and flow meter. These fittings should not
be connected directly to the valve or flow meter; preferably a
stainless wrap-around strap and supporting piece should be used.
If a pressure switch is used, the pressure adjustment for the switch
should be 50 percent of the minimum spray boom pressure
required. For example, if the minimum boom spray pressure is 20
pounds, adjust the pressure switch to 10 pounds. To adjust switch,
remove upper rubber stop and adjust Allen screw head inside top
of switch. The switch is N/O (Normally Open); The contacts will
close when the required pressure is correct. Use a multi-meter or
low voltage (1.5 D.C.) and bulb to indicate when switch contacts
are closed.

PRE-INSTALLATION REQUIREMENTS
Power Requirements
The power requirement for the Flying Flagman GMU system is 24 to
36 Vdc. The power requirement for the IntelliFlow® system is 24 to
36 Vdc. If the electrical condition of the aircraft wiring is unknown,
it is recommended that the power cables be wired from aircraft
master switch to the GMU and IntelliFlow breakers. This may
require the installation of a protection breaker close to the master
switch relay.
Grounding Requirements
Good grounding is essential for trouble free operation of the
GMU unit. Grounds should be connected to the GMU case, GMU
power cable, IntelliFlow case, clutch/brake interface control ground
cable (black), IntelliFlow power cable and to the IntelliMap power
cable. It is recommended that these grounds be connected
together at one single point to the frame/fuselage for easy
maintenance. The grounding point should be a perfect electrical
connection. Some case may require connecting grounding cables to
battery NEGATIVE ground points on the aircraft frame/fuselage.

CALIBRATION FACTOR
OBSERVATIONS
The CAL factor value depends on whether the CAL factor given by
the turbine manufacturer is specified in gallons or liters.
The Hemisphere GPS flow turbine CAL factors are in pulses per
gallon. The correct CAL factor is located around the turbine sensor.
Note: Keep a personal record of the turbine CAL factor
according to turbine serial number.
The CAL factor that must be entered into the GMU is the same as
for the turbine unit if the spray units are in gallons and the flow
turbine CAL factor is pulses per gallon.
The final entered CAL factor is close to 3 to 4 percent less than the
manufacturer’s CAL factor given against water when a flow turbine
meter is new and the metered flow is not water.
The following examples are given for water:
Example 1:
The Hemisphere GPS (15 to 180 GPM) flow turbine meter with 382
pulses per a gallon marked when new (part number 29-C-0305),
would require entering into the GMU (Setup/8/3) at 3 percent less
(370.54 pulses per a gallon), at 4 percent less (366.72 pulses per a
gallon).
36
Example 2:
The Hemisphere GPS (15 to 180 GPM) flow turbine meter with 382
pulses per a gallon (part number 29-C-0305), but converted to
pulses per a liter, would require entering into the GMU (Setup/8/3)
at 3 percent less (97.88 pulses per a liter), at 4 percent less (96.87
pulses per a liter).
The CAL Factor turbine flow unit conversions are:
Convert gallons to liters: X 3.785411
Convert liters to gallons: x 0.264173

FLOW DIAGNOSTIC RUN SCREEN
The IntelliFlow will go through an open and close cylce and then
position itself 3/4 open during a normal power sequence.
Check the following if the control valve motor does not rotate
correctly:
•
Is the by-pass switch in normal?
•
Is the pressure sensor circuit shorted?
Note: This could be normal if using a microswitch on the
spray handle.
•
Check the power to the IntelliFlow device.
•
Check the 10 Amp breaker and/or fuse on the IntelliFlow
control box.
The IntelliFlow status run screen is activated by entering the

Appendix A: M3/IntelliFlow Troubleshooting
Basic IntelliFlow Aircraft Troubleshooting
In normal operation, apply aircraft power to the IntelliFlow control
unit. Note the following:
•
Wait 10 to 15 seconds for the IntelliFlow controller
microprocessor to initialize. The microprocessor startup
can be heard with a low beep if ambient noise is low.
•
Wait and listen for the control valve motor rotation. The
motor will rotate to fully open, rotate to fully closed, then
finally reposition to 3/4 open.
If the IntelliFlow does not cycle:
1.
Ensure that the override switch is in the normal position.
2.
Ensure that there is power to the IntelliFlow controller and
controller fuse.
3.
Ensure that the pressure switch is normally open and working
properly.
4.
Check the fuse.
•
Confirm that the aircraft power has been removed from
the IntelliFlow controller.

Remove the fuse from the IntelliFlow controller and inspect
the fuse for signs of over current.
Note: Voltage sent to the Normal/bypass switch from the
IntelliFlow controller does not pass through the 10 Amp fuse

IntelliFlow controller malfunctions, allowing the control
valve motor to rotate to the open position.

Reset the system and check for normal operation. If the
system responds, then there is a problem with the
pressure switch.
If the valve functions properly, but the system still will not

If valve motor rotation is normal:
1.
Check the voltage across the flow control sensor contacts if the
motor does not rotate. The voltage should be logic 5 VDC.
2.
Check the sensor cabling and/or sensor if the voltage across
the sensor is 0 Vdc or less than 4 Vdc.

1550 = 3/4 open +/- 50
If the DISPLAY, 7 Run Screen is blank or the status does not
change, the most probable causes are:
•
Defective IntelliFlow control unit (serial port problems)
and/or
•
Incorrect M3 setup. See Chapter for further information
about flow screens and correct setup parameters.
A transducer sensor can be connected to the cable that is
normally connected to the flow turbine unit if a spare
transducer is available. Pulses can be generated and observed
on the CPU by passing or tapping an iron object over the pickup point of the sensor. This can also be used as a general
reference to the working condition of the IntelliFlow control
44
unit and M3. Simulated flow information can be observed in
Display, 7 and Run Screens 9 and 00.
Note: These simulated pulses are not sufficient for accurate
testing, but are sufficient for checking cables, IntelliFlow
control unit I/O ports, interface between the IntelliFlow
control unit and M3 and general display operation. Adjust
for 200 Hz sqare wave, amplitude close to 150 mv, 0 offset,
If a simple function generator is available. Connect the FG
to the sensor connector to produce pulses and check
dynamically the IntelliFlow system. See the next system,
“IntelliFlow Bench System Testing” for additional
instructions.
Warning!
Do not install fuses greater than 10 Amps for the IntelliFlow
control unit. Use the same type of fuse. A greater fuse valve
will cause internal damage to the IntelliFlow control unit.
9.
Check the following if the unit is blowing fuses:
•
Fuse is lower incorrect valve
•
Aircraft IntelliFlow cable installation
•
Aircraft IntelliFlow grounding connections
•
Aircraft battery charging system, alternator/regulator/etc
•
Aircraft battery state (common problem)
10. In addition to the following procedures, check the following:
45
•
Check all wiring connections and terminal strips.
Note: This will avoid ground loops and faulty connections.
Above all, avoid shorts to ground that will damage the
IntelliFlow control unit and/or motor control unit. Check the
IntelliFlow Control Unit grounding cable and grounding lugs.
•
Check that water or chemicals have not seeped into the
IntelliFlow control unit or motor control unit. It is a good
practice to have the water resistant canvas cover over the
motor head if the aircraft is flown under adverse conditions.
•
Check that the aircraft electrical system does not
experience noisy or transit voltage problems. The
IntelliFlow control unit can operate within a range of 20 to 32
Vdc. The voltage range must exceed 20 Vdc to modulate the
motor and valve mechanism at the desire time rate.
•
Check that the sensor unit and connector do not have
water or chemicals inside.
•
If the flow turbine unit that does not respond correctly or
does not indicate pulses/flow on touchscreen, the problem
is generally caused by a gumming of the turbine blades
and internal bushings.
Note: This can be avoided by washing the hopper/boom
system thoroughly and methodically after spray sessions.
Note: If the flow turbine unit is totally bummed-up, the unit
must be removed and cleaned on the bench. This requires
disassembling the unit and reassembling it.
•
If highly corrosive products are used, it is recommended
that the valve stem be lubricated with a few drops of
pneumatic turbine lubricating oil or, if not available, low
viscosity lubricating oil every 20 to 30 hours of spray time.
46
This will avoid gumming and/or chemical corrosion buildup
around valve stem and/or gland sealing components.
Penetrating oil can be applied if required. Use products
such as WD-40® or any quality penetrating oil before
lubricating.
•
The valve stem gland-retaining nut must not be tightened
without due understanding of the sealing method of the
valve stem. Any incorrect adjustment to the tension of the
gland-retaining nut can adversely change the torque
required to rotate the valve stem. This will cause the
motor valve transmission and/or motor to over work,
possibly causing damage.
Note: If the valve stem starts to gum-up, the motor valve
will not respond to the IntelliFlow commands with the
desired response. If the valve stem becomes too tight this
can be detrimental to the motor valve transmission and
motor, and cause excessive current through the power IC
chip inside the IntelliFlow control unit.
47
IntelliFlow Bench System Troubleshooting
Note: It is mandatory to have a bench setup with known
working cables and proven test units for successful. For
example, IntelliFlow control unit, control valve motor,
IntelliFlow cable set up and a M3 unit with all the cables and
accessories. General test equipment is needed. If a simple
function generator is available, adjust if for 200 Hz square
wave, amplitude close to 150 mv, 0 offset. Use a toggle
switch for sensor logic cable.
Note: The following procedures will vary depending on
which unit is being tested.
1.
Confirm that the‘ bench power is removed from the IntelliFlow
control unit.
2.
Remove the fuse from the IntelliFlow control unit and inspect
Note: Voltage sent to the normal/bypass switch from the
IntelliFlow control unit does not pass through a 10 Amp fuse

Connect the power cable and the control valve motor cable to
the IntelliFlow control unit.
4.
Connect the control valve motor to the control valve motor
cable.
5.
Toggle the normal/bypass switch to the normal position.
6.
Toggle the flow sensor switch to the open position.
48
7.
Apply 28 Vdc bench power to the IntelliFlow control unit. Note
the following:
•
Wait 10 to 15 seconds for the IntelliFlow control unit
microprocessor to initialize.
Note: Microprocessor startup is a low beep.
•
Note the control valve motor rotation. The motor will
rotate to fully open, then rotate to fully closed, then finally
reposition to 3/4 open.
•
If the control valve motor does not rotate:
1. Power to the IntelliFlow control unit must have the
correct current requirement.
2. Control valve motor if under test.
3. IntelliFlow control unit if under test.
If the valve motor rotation is normal:
1.
Remove the bench power from the IntelliFlow control unit.
2.
Connect the aux switch I/O connector to the IntelliFlow control
unit and M3 mainframe.
3.
Confirm that the normal/bypass switch is in the normal
position.
4.
Apply bench power to the IntelliFlow control unit.
5.
6.
Note the control valve motor position. The motor will rotate to
fully open, rotate to fully closed, then finally reposition to 3/4
open.
7.
Check the voltage across the sensor toggle switch if the motor
does not rotate (the voltage should be logic 5 Vdc).
8.
Check the IntelliFlow control unit if the voltage across switch is
0 Vdc or less than 4 Vdc. This could be a possible internal logic
problem.
49
If the previous operation is normal:
1.
Toggle the sensor switch to the closed position.
2.
Power cycle the IntelliFlow control unit. The control valve
motor should not rotate.
3.
Check the IntelliFlow control unit if the motor rotates with the
toggle switch is closed.

Toggle the sensor and observe the status change from 44 to
C4 and visa versa.
5.
Toggle the normal/bypass switch to the bypass position, motor
fully open.
6.
If the Display, 7 Run Screen is blank, then the most probable
causes are a defective IntelliFlow control unit (serial port
problems) and/or incorrect M3 setup.
7.
8.
Toggle the sensor switch to the closed position. If the toggle
sensor switch is in the open position, the pulses, GPM/LPM,
Area and Gal/Ac/Lit/Ha will not be displayed and will not
change value on the touchscreen under the following simulated
conditions.
9.
Connect a GPS antenna to the M3. Connect a differential
source to the M3 if possible.
10. Connect a function generator, adjusted for 200 Hz square
wave, amplitude close to 150 mv, 0 offset, to the cable that
connects to the flow turbine unit sensor.

11. These generated pulses will provide a stable flow source for
accurate bench tests. This dynamic data interchange of
information between the IntelliFlow control unit and the M3
mainframe can be evaluated using the M3-Display.
12. The test/simulate menu function allows the user to test the
operation of the M3 system by using GPS position utlities to
stimulate the flight pattern without the need to fly the airplane.
13. Simulate the flow rate by using a function generator and GPS
position utility for testing.
14. Check the touchscreen to confirm simulate.
15. It is important to keep the field and flow parameters within a
reasonable range of values to accommodate the flow pulses
received from the function generator.
16. When the M3 is in the simulate run mode, the speed can be
changed by using the up/down arrows on the touchscreen.
Each key is equal to 1 mph +/17. An additional test can be made to the IntelliFlow control unit
and control valve motor by using the 05-N2148 download

Use the following steps for
1.
The Spray Of Solid State Interface (SOSSI) unit can be
installed in any dry and secure part of aircraft. The maximum
distance from M3/GMU unit can be 15 feet owing to the signal
control cable. The clutch/brake control cable is 15 feet long.
The clutch/brake control cable should be connected as follows:
•
White wire connected to clutch/brake circuit breaker (load
side)
•
Black wire connected to qualified aircraft frame ground
•
Green wire connected to clutch/brake control solenoid
(load side)
2.
The SOSSI unit can be installed in aircraft cockpit visible to
pilot. This method will provide visibility of red led; red led will
glow when clutch/brake circuit is activated. (No Spray/Spray
Off)
3.
Do not install fuses greater than 8 Amps for the SOSSI unit.
Use the correct fast blow type fuse. If a larger fuse value is
used, this will cause internal damage because the current
exceeds the unit current load capacity.
4.
Check the following if the unit is blowing fuses:
•
Fuse is lower incorrect value.
•
Check interface system cable installation for dead short or
low resistance to aircraft ground.
•
In order to find the following problems, disconnect ground
return wire from the clutch/brake.
•
In particular, check green wire to solenoid load side for
short or low resistance to aircraft ground.
73
•
Check wire from solenoid load side to the clutch/brake for
short or low resistance to aircraft ground.
•
Disconnect all wires to solenoid and check for internal
resistance between contacts, coil and solenoid metal case.
•
Disconnect both wires from the clutch/brake and check
each wire for resistance to the clutch/brace metal case.
•
Check diodes across the clutch/break and solenoid if used
for short or low resistance. Diodes should read low
resistance in one direction and high in the reverse
direction.

Note 1: The brake is on (no spray) when the red LED is on.
Note 2: GMU mainframe requires that pin A on connector
P3 (data) be connected to pin S on P6 (Gp I/O). Use solid 28
Awg insulated wire. This will provide 12 VDC for the
interface device.
Note3: The M3 mainframe requires Pin 4 of connector com.
1 have a 12 volt modification. See the “Modify the M3 for
Variable Rate with IntelliFlow and “Spray Off” Controller”
bulliten, released on January 8, 2007, for more information.
Warning!
Only use an 8 Amp fuse (fast blow).
