High Yield Reading
After Stopping
C1 value (calibration
number that
eliminates false grain
flow from vibration)
must be adjusted. Refer to “Calibrating for Vibration (C1)” in
Calibration Section.
Average and
Instantaneous Yield Do
Not Agree The acre calibration
is not set to 100% The instantaneous yield does not account for the
acre calibration number and thus can give a
different yield from the average yield if the Area
Cal number is much different from 100%. Press
MENU, CAL and AREA to display Area Cal. See
“Incorrect Acre Counting” in this section if the
number is not 100%.
Elevator speed is zero or
erratic. NOTE: Elevator
speed must be between
250 and 600 rpm or there
will zero flow in bu/hr. Electric header clutch
not engaged. Engage electric header clutch.
Monitor set on wrong
elevator pulses per
revolution. Press MENU, SETUP and VEHICLE. Elevator
Pulses/Revolution appears at top of display. Refer
to initial calibration sheet, then press EDIT and
use up/down arrow keys to set pulses correctly.
Elevator speed sensor
is bad or monitor
cables have a bad
connection. While harvesting, determine if the low-elevator-
shaft-speed alarm is on. This indicates low or
erratic elevator speed. If the alarm is on:
• At elevator speed sensor cable, disconnect
monitor elevator speed cable. If the alarms is still
ON replace elevator speed sensor.
• If the alarm goes OFF when cable is
disconnected, inspect and reconnect cable.
Inspect monitor cables for signs of pinching or
cutting.
Use a volt-ohm meter to check for shorts and
continuity in elevator speed cable, distribution
cable, and cab cable. Refer to Reference Section
for proper readings.
Ground speed and
elevator speed
extension cables have
been interchanged. On the distribution cable, look at the labels on the
elevator speed and ground speed cables to ensure
they are connected correctly.
