speed must be between
250 and 650 rpm or there
will zero flow in bu/hr.
(cont) 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
