Buhler 2425, 2335, 2290, 2375, 2360 manual Normal Operation Electronic Instrument Control System

SECTION 2 - OPERATION

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
