    • ®IntroductionCaterpillar DataView is a portable diagnostic tool that allows data, measured by sensorstemporarily installed on Caterpillar products, to be viewed on a Personal Computer (PC). Itallows many of the individual hand-held diagnostic tools currently being used by servicetechnicians to be replaced with a single unit. DataView can be used with all Caterpillarproducts, both new and old.Caterpillar DataView consists of a portable hardware instrument (DataView hardware) whichconnects to a standard PC via the parallel printer port and a Windows-based software program(DataView software) that runs on the PC. The DataView software program provides setup,digital displays, graphs, and data logging of the measurements being taken. The hardwareaccepts up to nine standard Caterpillar sensors. A parallel port on DataView is provided foroperating a printer when DataView is attached to the PC. DataView is powered from theinternal batteries for portable use, or external power.Features• Six analog inputs for measuring pressure, temperature, blowby, and position.• Three frequency inputs for measuring rpm, Hz, duty cycle, hydraulic flow, and fuel flow.• Calculated channels for displaying sum, difference, burn rate, and hydraulic horsepower.• Two engine set point inputs.• Uses standard Caterpillar diagnostic tool sensors.• Automatic sensor identification of analog sensors, using auto ID cables.• RS232 input connector for 146-4080 Caterpillar Digital Multimeter (DMM).• Data logging on PC memory card.
    • Software FeaturesThe following screen views show how the different tools look in the DataView software.Setup ToolThe Setup Tool helps you select what sensors are available and tells DataView what sensorsyou will be using on each channel. It is the first window you will see after connecting theDataView hardware and software. The Setup Tool lets you specify what type of sensor isattached to each channel. You assign units (Metric or English) to the channel, assign uniquenames for easy identification, set low and high alarm values, set display rate, choose a positionprobe polarity, and set the filter level to one or more channels. As you set up channels thecurrent output of the channel’s sensor is visible on the setup screen. You can set up channelsfor immediate or future use. Setups created for future use can be saved as a permanent group.
    • Defining SensorsTo select a sensor and set up a channel, double-click on any channel and the Define Channelbox will appear as shown below.If you install the DataView software on your PC, you can try this even if the DataView hardwareis not connected.From the list of available sensors, select one by clicking on it. You can then select the units andchange any of the names or values in the boxes. When you select OK, that sensor will beinstalled on the selected channel.
    • Status ToolThe Status tool shows the real-time values for each channel. As well as a digital value, it canalso display an analog bar graph for each channel. A “Zoom” feature provides easy readingfrom a distance.
    • Setup LoggerThe Data Logger tool allows information from all channels to be recorded on a PC memory card.The PC memory card provided with DataView has a 2 MB capacity, but larger cards up to 16MB can be used. The recording can be started manually or automatically and samples can betaken up to 1000 times per second. This allows the recording of fast events such astransmission clutch shift times.
    • Graph ViewerThe Graph Viewer tool combines both Strip Chart and Histogram (Bar Graph) tools. You canchoose between logged data files on the PC, real time from the DataView hardware, or loggeddata files on the DataView hardware. Once the data source is selected, you can select eitherthe Strip Chart or the Histogram graph type. A Graph Definition Wizard allows you to selectexactly how you want to set up the strip chart graphs. Up to four separate strip charts(channels) can be seen on one graph, each with a separate scale. Two of these graphs can beshown at the same time for a total of eight individual channels displayed on the screen.The above Strip Chart graphs represent an actual hydraulic system and engine performancetest on a 426C Caterpillar Backhoe Loader. These traces were recorded using the Data ViewData Logger function so they can be stored and observed later. With the graphing tool you canalso look at graphs in real time while performing a test.The top graph has three traces which represent the Hydraulic System Performance over aperiod of time while the backhoe is being exercised. The two similar traces are the HydraulicSystem Pressure and the Hydraulic Signal Pressure. The third trace is the pressure differencebetween the first two pressures, and is called the Margin Pressure. With this graph it is possibleto determine what the pressure is at any time during the test and if these pressures are withinspecifications.The lower graph shows engine performance. The top trace is engine speed (RPM). At the 15second time line, the engine speed is at low idle. Next the engine goes to High Idle (Max RPM).Then a load is put on the engine with the hydraulics and the engine speed trace shows the fullload RPM. The lower line shows inlet manifold pressure, or engine boost. When the engine isat full load RPM, the maximum boost pressure can be observed. The advantage of using thegraph function is the ability to view and record many measurements during or after a test.
    • These 426C Graphs are stored on the DataView software program provided with ServiceTechnician’s Workbench. To view these graphs, load the DataView program and follow thisprocedure.1. Start DataView program.2. Click on the Graph Viewer icon in the DataView software toolbar. A window named “PC Log Selection” will appear.3. In this window, click on the option entitled “426C Performance” from the File box.4. Click on the 426C graph in the Documents box and click OK.5. Select the stripchart button to view that graph type.6. Add the channels you wish to include in your graph by highlighting the channels (one by one) in the Available Channels list box and press the “Add>>” push button. The selected channel is moved to the Selected Channels list box. Repeat this procedure to add additional channels.7. Press the “Finish” push button.8. When the Graph Selector dialog box appears, press the “OK” button. The graph is displayed.SensorsTwo types of sensors are used, Analog and Frequency sensors. DataView accepts manysensors already in use with Caterpillar diagnostic tools. The analog sensors are used formeasuring pressure, temperature, blowby, or position. These sensors can be used in any of thesix analog channels (channels 1 – 6) of the DataView hardware.Frequency sensors are used for measuring speed (rpm), frequency (Hz), %Duty Cycle orflowmeters. They provide a frequency or pulsed output signal and can be used only in the threefrequency channels of DataView (channels 7, 8, 9).A few of the many sensors available are listed below. A complete list and specifications of allsensors can be viewed by ordering literature number NELG5023, as well as looking in section28 of the Cat Tools & Shop Products Guide. This information is also shown in the DataViewuser’s manual Form NEHS0662. Analog Sensors for DataView Pressure 143-4062 0-689 kPa (0-100 psi) Pressure 143-4065 0-6890 kPa (0-1000 psi) Pressure 143-4066 0-51675 kPa (0-7500 psi) Probe Type RTD Temperature 4C-6264 25.4 mm (1”) long, 3.2 mm (.125”) diameter (various lengths available) Exhaust RTD Temperature 4C-6268 Exhaust RTD Temperature Sensor Blowby 8T-2685 Small Blowby/Air Flow Pickup (Part of 8T-2700 Blowby Group) Frequency Sensors for DataView Photo Pickup Speed 9U-5140 LED Photo Pickup Photo Pickup Speed 6V-3137 Magnetic Mounting Base for 9U-5140 Photo Pickup Speed 1U-6605 Retro-Reflective Tape, 12 mm (5’ long) Injection Line Speed 6V-4950 Injection Line Pickup Group Tach Generator Speed 5P-7360 Tach Generator (20 Tooth Int.

    • PWM/Analog Sensor Adapter KitThe Caterpillar 153-9630 PWM/Analog Sensor Adapter Kit allows the DataView hardware to beused to test, monitor, graph, and Data Log the output of most permanently installed sensors onCaterpillar electronically controlled engines and equipment. This is very helpful for locating aintermittent sensor, or verifying if a sensor is bad when ET indicates a fault code for that sensor.The kit provides the necessary adapter box (for PWM sensors) and cables (for PWM andAnalog sensors) to properly connect these sensors to DataView. The sensors can be testedeither removed from the machine or installed on the machine, and testing will not interfere withthe operation of the machine or engine. While testing sensors removed from the engine, theSensor Adapter Kit powers the sensors via an internal power supply.Autoranging MultimeterThe Caterpillar 146-4080 Multimeter takes measurements on all Caterpillar products includinggenerator sets. Measurements performed by the Autoranging Multimeter include voltage,current, temperature, duty cycle, frequency, diode check, continuity, and impedance. It can beconnected to the DataView hardware using the optional 146-8488 RS232 cable. This allowsDMM readings to be viewed with other DataView measurements and data logged or used withother programs. The Digital Multimeter Group includes the multimeter, test leads, type Kthermocouple, and soft holster.
