The Vital Information Display System(VIDS) provides the operator withcontinuous feedback on machine andsystem operation, and includes threelevels of operator alert.

The reliable, easy-to-read monitoringsystem also records performance datafor assistance in diagnosis and fasttroubleshooting.

The system consists of three displaymodules:

1 Gauge cluster module consists offour electronically driven analoggauges which display enginecoolant temperature, transmissionoil temperature, hydraulic oiltemperature and fuel level.

2 Speedometer/tachometer moduleincludes an analog tachometer,ground speed and gear/directionreadouts.

3 Message center module providesa variety of component and systeminformation through a universalanalog gauge and a digital messagereadout display. The switchablemessage center allows the operatorto access information on severalmachine functions through theuniversal gauge, while digitallydisplaying the function name, statusand related instructions to theoperator.

The alert indicator lamp is also locatedon the message center. It is activated bythe main system module and flashes toindicate a serious or critical abnormalcondition.

An alert alarm is activated by the mainmodule to sound when a criticalabnormal condition exists.

The keypad allows access to diagnosticdata recorded in the main monitoringsystem module and a menu systemwhich can tailor machine performanceto an individual operator.

Examples of system information are:

■ Engine oil pressure, engine boostpressure

■ Power train oil temperature

■ Main hydraulic pump pressure, bladeheight

In standard operation the first line ofinformation in the message center isstatus and the second line ofinformation is a selected gaugeparameter.

Automated Blade Assist (ABA) is a semi-automatic dozercontrol function that increases efficiency and reduces operatorworkload by automating some of the more common bladefunctions. The ABA system for Carrydozer tractors consists ofAutoPitch, AutoSpread, and Auto Return.

AutoPitch allows the operator to preset blade pitch angles foroptimal performance during the dozing cycle: one setting eachfor load, carry, spread and return. Once the AutoPitch key isactivated on the VIDS keypad, the operator can select thedozing segment by pushing the yellow button on the left sideof the dozer handle.

AutoSpread raises the blade at an operator selectable rateduring the spread/dump portion of the dozing cycle.AutoSpread is activated on the keypad and is initiated bypushing the yellow button on the left side of the dozer handle.

AutoReturn will raise the blade fully to the end of the dozingpass and then return the blade to a starting pitch and height tobegin the next dozing pass. AutoReturn is activated on thekeypad and is initiated when the tractor is placed into reverse.

Automatic Tilt limiting function helps the operator to keep thepusharms from interfering with the track. Low-effort,automatic control functions increase productivity.

1 Thumb button selects doze segment. First hit actuatescarry (lays the blade back), second hit actuates auto dump.

2 Thumb button returns blade pitch to “ready to carry”.
