Display Components of the Caterpillar Monitoring System (1) Main Display Module (2) Gauge Clusters (3) Alert Indicators (4) Display Area (5) GaugesNormal Mode is Mode 0. Normal Mode is used during normal engine operation. When the main display module is in Normal Mode, the Main Display Module and the Gauge Cluster Modules show the following conditions to the operator.
Proper operation of the Caterpillar Monitoring System is shown. A Self Test is performed. During the Self Test, all of the elements of the display and gauges briefly operate. For more information on this subject, see Testing And Adjusting, "System Self Test".
A value for system condition is shown. The Main Display Module continuously monitors engine systems. The needles in the Gauge Cluster Modules indicate a normal operating condition when the needles are pointing straight up.
The system shows if an engine problem exists. When an abnormal condition (problem) exists, the corresponding Alert Indicator flashes and the Action Alarm sounds. For information on this subject, see Systems Operation, "Warning Operation".
The system shows if a diagnostic code exists. The Main Display Module continuously checks for diagnostic codes in the Caterpillar Monitoring System and the engine Electronic Control Module (ECM). When a diagnostic code is detected, the Display Area (4) shows "SERV CODE" and the Shutdown/Diagnostic alert indicator lights. For more information, see the Electronic Troubleshooting Guide for the engine that is being serviced.Operator Modes
In Normal Mode, the six digit display area (4) is used to show various engine system conditions to the operator (Operator Modes). A list of possible operator modes is shown in Testing And Adjusting, "Modes Of The Main Display Module".When the Main Display Module enters Normal Mode, the default condition is shown on the six digit display area. This condition is normally the engine rpm. A "SCROLL" switch is available to the operator when the parameters for the operator are available. The "SCROLL" switch connects to one of the uncommitted switch inputs (operator switch inputs) of the Main Display Module. See the Electrical System Schematic for the engine that is being serviced in order to determine the uncommitted switch that is being used. The "SCROLL" switch will cause the six digit display area to scroll through the available parameters. Releasing the "SCROLL" switch will stop the scrolling on the currently shown parameter.Mode numbers are not displayed when the parameters for the operator are scrolling. The most common modes are shown in the following list. Service Meter Mode - There is a value on the six digit display area. The symbol for the Service Meter is ON.DC System Voltage - There is a value on the six digit display area. The symbol for Volts is ON.Digital Tachometer Mode - There is a value on the six digit display area. The symbol for RPM is ON.Diagnostic Scrolling Mode - Diagnostic Scrolling ModeFor more information on Operator Modes, see the corresponding mode in Systems Operation.Service Meter Parameter
