SECTION 2 - OPERATION
External Alarm Control Conversion - Each tractor is manufactured so that the Electronic Instrument Control System can be converted to inform the operator, via the electronic monitor and audible alarm, that there is a problem with an outside source (i.e., a towed implement that is powered by a separate engine).
If the tractor Electronic Instrument Control System receives a signal from an external source, the upper portion of the electronic monitor will flash “EXT” “ALR”. The audible alarm will beep rapidly. 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 “EXT” “ALR” display by pressing the acknowledge/reset button. The audible alarm and display will return if the external signal is received by the monitor again.
NOTE: On tractors equipped with a Tractor Performance Monitor (TPM), the external alarm feature will activate when the “% slip” or “Time of Day” alarm settings are reached. See the TPM operation section of this manual for further information.
When the external audible alarm control is enabled and a signal is received by the Electronic Instrument Control System from an outside source, the automatic shutdown feature will not be engaged.
Tractors are assembled with the external alarm control feature disabled. The operator has the option of enabling the feature at any time.
If the operator desires to enable the external alarm control feature, proceed as follows:
1.Unhook the battery cables from the batteries. This will prevent any possibility of an accidental short while making the conversion. See Section 3 for information on how to disconnect the cables.
NOTE: Disconnecting the batteries will not remove any calibration numbers from the memory of the Electronic Instrument Control System. If the tractor is equipped with the optional Tractor Performance Monitor (TPM), the TPM may have to be reset.
