SECTION 2 - OPERATION

AUDIBLE/VISUAL ALARMS OF THE ELECTRONIC INSTRUMENT CONTROL SYSTEM

Low Transmission Lube Pressure

The Electronic Instrument Control System will notify the operator that the transmission lubrication pressure is below 21 kPa (3 PSI) and the quantity of oil entering the transmission is not adequate to properly lubricate the internal components. See “Transmission” in Section 4 for possible causes of low transmission lube pressure. Failure to correct the low pressure condition can cause serious damage to the transmission. The following description details the reaction of the electronic monitor and audible alarm in the event of low transmission lube pressure:

With the engine running and transmission lube pressure below 21 kPa (3 PSI), the transmission pressure warning light, 1, on the warning light bar will illuminate. There will be a six-second delay before the audible alarm sounds a solid tone for four seconds. The upper portion of the monitor will flash “CHK” “LMPS,” indicating the operator should look at the light bar to determine the function causing the alarm to sound, i.e., transmission lube pressure. The lower portion of the monitor will continue to display whatever is selected on the rotary select switch.

The operator can cancel the audible alarm and the “CHK” “LMPS” display on the upper portion of the monitor by pressing the acknowledge/reset button once. The transmission lubrication light on the warning light bar will stay lit until the low pressure condition is corrected. The audible alarm and “CHK” “LMPS” display will not return until the ignition switch is turned to the “OFF” position and the tractor is restarted.

Transmission lube pressure is considered a non-critical alarm function and will not cause the electronic monitor to go into the “STOP” mode or cause the automatic shutdown to activate.

ATTENTION: It is important that the operator shut the tractor off and find out the cause of the low transmission lube pressure light indication. Take corrective action immediately to prevent damage to the transmission.
