SECTION 2 - OPERATION

ELECTRONIC INSTRUMENT CONTROL SYSTEM

The 2290, 2335, 2360, 2375 and 2425 tractors are equipped with an Electronic Instrument Control System designed to provide the operator with information concerning tractor functions, calibration procedures to meet specific operation requirements, and serve as a visual and audio warning system of malfunctions that have occurred in the tractor operating systems.

The Electronic Instrument Control System is comprised of four dash-mounted components and various senders and switches located throughout the tractor. The four dash-mounted components are identified as follows:

1Electronic monitor digit select switch

2Electronic monitor

3Electronic monitor acknowledge/reset button

4Electronic monitor rotary select switch

Electronic Monitor Digit Select Switch

The electronic monitor digit select switch is a five-position switch used to select digits and units of measurement during the calibration of the electronic monitor:

Center - neutral position

Up - changes the selected digit upward between zero and nine. Tapping the switch changes one value at a time. Holding the switch up will roll the numbers.

Down - changes the selected digit downward between nine and zero. Tapping the switch changes one value at a time. Holding the switch down will roll the numbers.

Left - selects the next digit position to the left. Right - selects the next digit position to the right.

The switch does not function during normal operation of the tractor, but only when the operator has selected the calibration mode to program the system for specific operational requirements.
