When the desired counter number is displayed, press the “-”
(RESET) button and LAr will be displayed. See Illustration
to the right.
WARNING: Holding the “-” (RESET) button for 12 seconds
will clear both the #3 AREA counter AND the #3 WEIGHT
counter whether the rotary switch is in the AREA or the
WEIGHT TOTALS position.
If the “-” button is released before 1 second has elapsed, the
counters will not be cleared and the LAr message will be
replaced with the previous total.
After the “-” (RESET) button has been held for 1 second,
the LAr message will be replaced by 0.0, indicating that
counter pair #3 has been cleared. See Illustration below.
Pre-Field Sys tem Checkout
Before beginning actual planting, perform the following
“Pre-field” procedure to ensure that your settings, oil flow
and desired speed range will allow the DrillMaster to provide
the required application control. This procedure should be
repeated for each application rate or setting change. By
performing all of the steps listed below, you set up your
system to allow the DrillMaster to perform at optimum level.
NOTE: Pre-field System Checkout is a procedure performed
while the console is in the CAL mode. The Red WARNING
light will be lit during the procedure, and “CAL” will be
flashing on the display.
Start vehicle and pump, bring the engine up to normal
temperature and operating RPM. DO NOT exceed safe
system pressure.
ENTER MAXIMUM APPLICATION TEST SPEED INTO
CONSOLE
With console in HOLD, enter Calibrate by pushing and
holding CAL button. The CAL icon will appear on display and
the red light will be on. Turn rotary switch to TEST SPEED
position. Use “+” or “-” button to enter maximum application
speed. DO NOT exit calibration mode. CAL will flash on
the display indicating TEST SPEED mode. Select manual
(MAN) control and turn the appropriate section switches
on. Turn rotary switch to RATE position and hold “+” button
for approximately 30 seconds to completely open the PWM
valve (control valve).
CAN’T GET THERE?
If you can’t get to the desired application rate, you may
need to increase the volume of hydraulic oil available to the
motors.
ENTER MINIMUM APPLICATION TEST SPEED INTO
CONSOLE
Turn rotary switch to TEST SPEED position. Use the “+” or “-”
button to enter minimum application speed. DO NOT exit
calibration mode.
Turn the appropriate section switches ON (make certain
system is in MANUAL), turn rotary switch to RATE position
and hold “-” button until you achieve 10% less than your
desired application rate.
It is not normally a problem if the application rate goes all
the way to zero when holding the “-” button for 5 seconds
or more, as long as it goes back up when the “+” button is
held.
CAN’T GET THERE?
If holding the “-” button does not get the application rate
to go below the desired application rate, please refer to the

Troubleshooting
PROBLEM:
PWM Valve will not adjust Check electrical connections at PWM valve.
Check battery voltage.
No Meter RPM feedback Check wire connections to red sensors on end of each drill seed
box.
Check gap between sensor and sensor wheel. Gap should be
1/16” to 1/8”.
Replace faulty sensor.
Hydraulic motors will not run Make sure tractor hydraulics are on and owing in correct
direction.
Make sure tractor hydraulic ow is turn up to at least 3-5 gallon
per minute.
Turn all section switches ON.
Make sure it doesn’t say HOLD on the DrillMaster display screen.
When doing a Pre-Season Test be sure DrillMaster is in AUTO.
