Operation 13
Driving too slow will cause the servo valve to
end stop (fully close). When this happens, your
pressure gauge will show minimum PSI. The
console can no longer maintain the selected ap-
plication rate and will display LOW FLOW and
stop controlling.
To prevent a “LOW FLOW” message as you slow
down the 8160 can automatically stop reducing
the flow at a preset minimum flow rate. This pre
-
vents a poor spray pattern from your nozzles.
This option can be turned on and the Minimum
Flow Rate set in the OPTIONS Menu. This is only
available for the Spray Mode. Keep in mind that
you are OVERAPPLYING to maintain a spray
pattern at very low speeds. Whenever the flow is
reduced to the Minimum Flow level, the display
will flash “MIN” to indicate that the console will
not reduce the flow any further.
NOTE:
The following procedure can be used as
an alternative to using the Minimum Rate fea-
ture. After slowing down the console does not
control the servo valve but instead displays
“LOW FLO”, change the Rate switch to manual
and press “ ” key until you achieve operating
flow. Increase your speed then select rate 1 or
rate 2. The 8160 will again control your flow as
you increase your speed. Keep in mind that you
are OVERAPPLYING to maintain a spray pat-
tern at very low speeds.
VARIABLE RATE
The 8160’s Rate 1 can be changed “on the go”
by using the Variable Rate feature. An external
source must provide Application Rate informa-
tion to the 8160 in real time.
The information must be provided through the
RS232 port on the rear of the 8160 using either
the Hiniker Protocol or the Generic Protocal.
These protocols are listed in the appendix.
The external rate input will override the RATE 1
application rate data. The Rate Switch must be
in the Rate 1 position.
The Rate 1 Application Rate that was pro-
grammed in during Set-Up is not changed. The
console will use the variable Rate data until pow-
er is switched off. When the console is powered
back on, the original Rate 1 data will be used.
Note:
If you go into the Set-Up routine before
powering down, the 8160 will save the current
displayed Rate 1 data for Rate 1 when you exit
Set Up.
The console will display the current Rate on the
upper left of the display.
The 8160 will continue to apply at the rate speci-
fied in the last received message until it receives
a new message specifying a new application
rate.
Switching to MANUAL or RATE 2 will override
the external rate input.
Turning the console off will reset the Variable
Rate Data to the Rate 1 data that was originally
programmed in.
Cables are available for connecting to most Pre-
cision Farming Systems. Refer to the Hiniker
Parts Book for specific information. Refer to
the Manual supplied with the Precision Farm-
ing equipment for programming their console for
third party controllers.
The Hiniker Protocol requires a Null modem se-
rial cable.
If using the Generic protocol, program the Preci-
sion Farming Console as if you were connecting
to a Raven 440.
Do not divide the flow calibration number by 10
as instructed in some manuals. Use the calibra-
tion number listed on the Hiniker flowmeter.
For proper operation software version 3.0 or
higher is required. If you have earlier versions
the 8160 will need to have the software updated.
The software version is shown on the display
each time the 8160 is powered up.
