General
Make sure your system is properly calibrated before
beginning to apply product. We also recommend
completion of the Pre-Field System Checkout described on
pages 39-40 prior to beginning any field operations.
Press the ON/OFF button to turn the console on. After
displaying the hours of operation and software version, the
console will start normal operating mode.
The MT-3405F™ II can be operated in Manual (MAN) or
Automatic (AUTO) mode. In either mode, the right-hand
display will always show the Application Rate (except
when in HOLD or when displaying error messages, see
Troubleshooting section starting on page 33). The left hand
display will show data as selected by the rotary switch.
Manual Operation
The manual mode is used when the operator wants to
manually control the servo valve using the “+” and “-” keys,
and thus the application rate. The application rate (gal/
acre or liter/hec) will vary depending on ground speed.
Use the AUTO/MAN button to select MANual mode (“MAN”
icon will be displayed).
IN HOLD:
If the console is in HOLD, or if all Boom Valves
are OFF, the “+” and “-” buttons will not control the servo
valve unless the rotary switch is in the VOLUME/MINUTE
position. In that position only, the servo valve can be
adjusted without any boom valves on. This can be useful
for system pressure tests, etc.
Turn rotary dial to display desired readout.

Operation
IN RUN, WITH SPEED SIGNAL:
If the system is in RUN,
with at least one boom valve ON and there is a speed
signal, the “+” and “-” buttons can be used to adjust the
servo valve with the rotary switch in any position except
TANK, VOLUME, and AREA and the application rate can be
monitored on the right-hand display.
IN RUN, NO SPEED SIGNAL:
If there is no speed signal,
“no SPEEd” will flash in the right-hand display and the
Application Rate will be invalid. The “+” and “-” buttons will
adjust the servo valve if the rotary switch is in the VOLUME/
MINUTE position, and the flow rate (GPM or LPM) can be
monitored.
Automatic Operation
When the Automatic mode is selected, the console will
control the servo valve to maintain the desired application
rate (GPS/LPH) when the vehicle speed changes or when
booms are turned on or off. Press the AUTO/MAN button to
select AUTOMATIC mode; the AUTO icon will appear in the
display.
To operate the system in AUTOMATIC mode, turn on the
desired booms, toggle the RUN/HOLD switch to RUN, and
drive. IMPORTANT NOTE: In AUTO mode, when no speed
signal is available, the system automatically turns all booms
off. “no SPEEd” will flash in the right-hand display until the
vehicle starts moving, then the console will turn the booms
on and the Application Rate will be displayed in the right-
hand display. The system will automatically adjust the servo
valve to maintain the calibrated TARGET RATE (GPA/LPH).
ON-THE-GO “DELTA” RATE ADJUSTMENTS (ADJUST
RATE)
To adjust the target application rate on-the-go,
each time the “+” or “-” buttons are pressed, the TARGET
RATE will be increased or decreased by the amount of the
ADJUST RATE which was entered in calibration. Example:
calibrated TARGET RATE = 10.0 GPA and ADJUST RATE =
1.0 GPA, pressing the “+” key once will increase the target
rate from 10.0 to 11.0. The rate display will momentarily
show the new target rate of 11.0 and then show the actual
application rate. Pressing the “-” key once will decrease
the target from 11.0 to 10.0. NOTE: When you “DELTA”
the target rate, the display will momentarily show you
the new target rate and then resume showing the actual
application rate. The new target rate is maintained until
further adjustments are made using the “DELTA” feature
or calibration changes occur, or if the unit is turned off.
Important: to use the DELTA feature, the console must be
in AUTOMATIC mode and the rotary switch can be in any
position except TANK, VOLUME, or AREA.
IN HOLD: If the system is in AUTO mode and in HOLD or
all booms are off, the “+” and “-” buttons will adjust the
TARGET RATE with the rotary switch in any position except
TANK, VOLUME or AREA; CAUTION: we recommend that
the rotary switch is in the RATE position, because that is
the only position where the new TARGET RATE is displayed
while in HOLD. In RATE position, the left-hand display will
momentarily display the new TARGET RATE, then will revert
to .00, because all the boom valves are off so there is no
product being applied.
