The “Special” Calibration mode is used to set up system
parameters that rarely need to be changed or adjusted. To
enter Special Cal, put the system in HOLD, turn the console
OFF, press and hold both the AUTO/MAN button and CAL
button while turning console ON. The console will display
SPEC for 2 seconds to show that the console is in the Special
Calibration mode. Release the AUTO/MAN and CAL buttons.
The CAL icon and Warn LED will turn on. The desired Special
Calibration parameter(s) can then be accessed with the rotary
switch per the illustration below. To exit Special Calibration,
press and hold the CAL button for 2 seconds. The console
will store any changes and revert to normal operation.
NOTE: You must exit Special Calibration to save changes.

VALVE POLARITY:
If the hydraulic motor RPM increases
when the console is in Manual and the “-”
button is pressed, change the valve polarity
from Inline to Bypass or
vice versa.
CONTROL SPEED:
This setting is factory defaulted to -1
and can be adjusted from -5 to 3. If the Control
Valve is causing the Target Seed Rate to be
unstable then reduce the valve control speed.
RATIO:
Set this value to the ratio of hydraulic motor
revolution to seed
meter. It is factory set
to 4.000. The value for
Driven or Drive Sprocket
refers to the number of teeth on the sprocket.
See next page for “Calculating Ratio”.

MOTOR CAL:
Set this value to the number of pulses from
the hydraulic motor
per revolution. This is
factory set to 16 and
generally represents the
number of teeth on the motor sprocket.
AUTO SHUTOFF ON/OFF:
When Auto Shutoff is enabled
(ON), the hydraulic flow control valve will
run towards minimum flow for 4 seconds
anytime the system is put
in Hold - or all sections
are turned off, or if in
auto mode and speed
goes to zero.
START UP:
Start up time comes factory set to 0 and can
be adjusted to 2048. This value represents the number
of milliseconds the control valve will run
each time the system is toggled from Hold
to Auto. This setting should be set to 0
unless the Auto Shutoff is set to ON. Then
increase the start up
time to reduce the time
to reach Target Seed
Rate.
To exit Special Calibration, press and hold the CAL button for
2 seconds. The console will store any changes and revert to
normal operation.
NOTE: You must exit Special Calibration to save changes.
