SECTION 2 - OPERATION
2-29
With AREA selected, area accumulation can be reset
to zero by holding down the START/STOP switch, 3,
for three seconds until a “beep” is heard from the
audible alarm.
NOTE: If the radar option is not installed, area
calculations are based on axle speed and are subject
to inaccuracies caused by wheel slip that may be
present.
Wheel Slip (with Radar Option)
Touch the %SLIP selector switch, 4. The “%SLIP”
legend, 1, will display together with a two-digit slip
value, 2, in the main TPM display. The slip value is
detected by the comparison of theoretical ground
speed (axle rotation sensor) with true ground speed
(radar sensor).
Slip zero calibration occurs automatically. However,
when widely differing soil conditions are encoun-
tered, it may be necessary to manually zero the
wheel slip ratio, as follows:
Drive the tractor in the soil conditions to be worked,
with implement raised, at a constant speed of less
than 16 km/h (10 MPH). This will determine the
minimum wheel slip under light operating conditions
to be used as a 0% reference point. With % SLIP
function selected, hold down the START/STOP
switch, 5, for at least three seconds.
A “beep” from the alarm and “0” in the display
indicates that the module has been calibrated to a
minimum slip condition.
WARNING
The radar ground speed sensor emits a low
intensity microwave signal which will not cause
any ill effects in normal use. Although the signal
intensity is low, do not look directly into the face
of the sensor while in operation so as to avoid
eye damage.
IMPORTANT: Before carrying out arc welding on the
tractor or on any equipment attached to the tractor,
disconnect all power and ground leads from the
batteries in order to avoid possible damage to
electronic components.
Slip Alarm (with Radar Option)
A slip alarm point may be entered - see “EIC
Programming.” When wheel slip exceeds the value
entered, the alarm will sound for one second. If wheel
slip is selected, the “% SLIP”, 1, legend will be
displayed. In addition, the “ALARM”, 3, legend will
flash and continue to flash until wheel slip is reduced
below the present level.
