NORMAL OPERATION OF THE
ELECTRONIC INSTRUMENT CONTROL
SYSTEM
The following is a description of how the
Electronic Instrument Control System will work
at engine start-up and field operation. The
information is based on a tractor that has no
errors indicated and is properly calibrated.
Key to the “RUN” Position - Engine Off
Turning the key to the “RUN” position without
starting the tractor will cause the electronic
monitor to display all the LCD segments for one
second and the audible alarm to sound twice.
The display will then show zero and the engine
symbol in the upper half of the module. The
lower half of the module will display a readout
based on the position of the rotary select switch.
When the ignition switch turns to the “RUN”
position without the engine running, the system
also checks certain sensors and the operation
of the warning light bar. The warning light bar
activates these lights:
• Park Brake
• Safety Belt
• Alternator Output
• Engine Coolant Level
• Engine Oil Pressure
• Hydraulic Oil Temperature
• Transmission Lube Pressure
• Transmission Lube Filter
• Hydraulic Lube Filter
• Yellow Engine Warning
• Red Engine Warning
After several seconds, the system turns off the
Engine Coolant Level, Hydraulic Oil
Temperature, Transmission Lube Filter,
Hydraulic Lube Filter, Safety Belt, Yellow Engine
Warning, and Red Engine Warning lamps.
With the key in the “RUN” position, four lights will
remain on until the switch moves to the
“ENGINE START” position:
•
Park Brake
• Alternator Output
• Engine Oil Pressure
• Transmission Lube Pressure
