Buhler 2425 - Manual (Page 156)

SECTION 2 - OPERATION
2-98
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.
