Cat Dataview.

Cat Dataview is a portable diagnostic tool that allows data, measured by sensors temporarily installed on Caterpillar products, to be viewed on a Personal Computer (PC). It allows many of the individual hand held diagnostic tools currently being used by service technicians to be replaced with a single unit. Dataview also allows diagnostic data to be shared with other PC programs, such as the Cat Service Information System (SIS) and the Cat Electronic Technician (ET). Dataview can be used with all Caterpillar products, both new and old.

Cat Dataview consists of a portable hardware instrument (Dataview Hardware) which connects 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 hardware accepts up to nine standard Cat sensors. A parallel port on Dataview is provided for operating a printer when Dataview is attached to the PC. Dataview is powered from internal batteries for portable use, or external power.

Sensors for Dataview

Dataview accepts many sensors already in use with Cat diagnostic tools. This allows you to use sensors you may already have. The following lists allow you to determine which Cat sensors are available to obtain the measurements you desire. Dataview uses two different types of sensors, analog and frequency. An explanation of each and lists of available sensors follows.

Analog Sensors

Used for measuring pressure, temperature, blowby, or position. These sensors can be used only in the analog channels of Dataview hardware (channels 1 to 6). Analog sensors provide a continuous voltage, current, or resistance output signal, which is proportional to the data being measured.

Auto ID Cables

Used for analog sensor automatic identification and setup. When the proper auto ID cable is installed between the sensor and Dataview, the sensor will be automatically identified and set up ready for operation by Dataview. These cables come with a piece of heat shrinkable tubing, so they can be permanently installed on the sensors. Auto ID is possible because each cable has a different resistor installed in it to identify the sensor it is used with.

Pressure Sensors for Analog Channels

In addition to being used with Dataview, these Cat pressure sensors are used with the 4C-6500 Data Logger , 4C-6825 Basic Sensor Group , and the 4C-6811 Expanded Sensors Group . The connector on these sensors will not plug directly into Dataview. Either a 131-5054 Pressure Sensor Adapter Cable or the proper auto ID cable listed below for each sensor is required to connect these sensors to Dataview.

Illustration 8	g02562036
Pressure Sensors for Analog Channels. Refer to Tables 4 and 5 for additional information.

RTD Temperature Sensors for Analog Channels

Dataview uses RTD (Resistance Temperature Device) sensors to measure temperature. An auto ID cable is not required for RTD temperature sensors. They plug directly into Dataview analog channels and will be identified as a temperature sensor. This is the only type of analog sensor that does not require an auto ID cable. These RTD sensors are also used with these diagnostic tool groups: 4C-6800 Digital Thermometer Group , 4C-6800 Data Logger , 4C-6825 Basic Sensor Group , and 4C-6811 Expanded Sensors Group . Many different types of RTD sensors are available.

Locating and Mounting Dataview Hardware

To use Dataview, the hardware must be connected to a PC to set up the sensors and to view the data. For data logging, the PC is used to set up Dataview, but the logging can be done without the PC attached. The data will be logged on the Dataview memory card installed in the hardware. After logging is completed, the PC is then reconnected to view the logged data. So for most applications, the PC can be located near Dataview hardware. At other times, it may work better to locate Dataview near the sensors. An explanation of the various mounting methods follows.

Operation

Using Dataview Hardware at the PC

Illustration 25	g02562276
Using Dataview Hardware at the PC.

The most common method of using Dataview is to have the Dataview hardware located on the PC. Dataview can be mounted under the PC and fastened to it, if desired. Since it is about the same size as a laptop PC this makes a compact, one-piece package. This allows the PC and Dataview to be used as a single unit. The short 131-5053 Parallel Port Cable provided with the group is used to connect to the PC.

Dataview Portable Techstation

For protecting Dataview hardware and your PC, and to keep all separate components together, the 137-0173 Carrying Case is provided with the 131-5051 Dataview Portable Techstation Group . It has a storage location for Dataview in the bottom of the case. A door opens which allows input cables to be attached without removing Dataview from the case. The case has cutouts in the foam which hold a generic PC, Dataview, power supplies, and a communications adapter. This case and its components provide a complete diagnostic platform for field personnel.

Illustration 26	g02562278
Dataview Portable Techstation.

The top foam insert in the case, shown in Illustration 27, can be replaced with a 138-8779 Top Foam to hold the Cat Portable PC (Itronix). Refer to the Optional Items section of this manual for more information.

Illustration 27	g02562281
138-8779 Top Foam to hold the Cat Portable PC (Itronix).

Using Dataview Hardware Near Sensors

Dataview can be located up to 5.5 m (18.0 ft) away from the PC. This allows Dataview to be used as an input box located near the sensors. The advantage of this method is that short cables can be used from the sensors to Dataview inputs, but only a single cable is needed between Dataview and the PC. This makes it easier to locate the PC in a location such as the cab of a machine. However, this method should be used only when Dataview is in a protected location where it will not be exposed to the weather damage.

Show/hide table

NOTICE
The Dataview hardware case is not a sealed enclosure and damage can result by exposing it to rain, moisture, excessive heat, or excessive vibration. Do not mount on track-type tractors.

Mounting Dataview Hardware on a Machine

It may be necessary to mount Dataview on a machine and operate the machine for tests or data logging. While Dataview is designed for field operation, it is not designed with a waterproof case. This should be kept in mind when choosing a mounting location. It should be installed in a location where it will be protected against liquids or placed inside a waterproof enclosure. Also, avoid locations that are subjected to excessive heat and dirt. Dataview has slots in the side to allow mounting brackets to be installed. These brackets can be held in place by tightening the screw in them.

Dataview is not designed to be mounted directly to a track-type tractor due to the excessive vibration encountered during operation. However, it may be soft mounted in the cab with foam rubber isolation.

Selecting a PC for Use With Dataview

When selecting a PC to use with Dataview, check the specifications for the PC in the Dataview Specification section of this manual. Even if these specifications are met, Dataview may not work on every PC. The parallel port on some computers may be wired or configured in such a manner that it will not communicate with Dataview. A test program is available to test your computer. If it fails this test, you may be able to change the setup on your computer so it will work with Dataview. Call the PCDR hotline at 1-(800) THE PCDR (, 1-800-843-7237).

Note: A free program is available to test your PC to see if it will operate with Dataview. Contact CSTG for your free program. Also a 142-2415 Parallel Port Test Connector is required for testing your PC. This connector and the test software is included with the 131-5050 and 131-5051 Dataview Groups. Instructions are included on the software test program screen.

Powering Dataview Hardware

Dataview hardware operates from an internal battery pack, but can also be powered from an external power source. It can be powered by 110 to 220 V AC, directly from a machine battery of 11 to 40 V DC, or using a vehicle 12 V cigarette lighter. This allows for extended long-term operation for long-term operations. A detailed description of each of the methods of powering Dataview is given in the following paragraphs.

Internal Power

Dataview has an internal battery pack for portable operation. This battery pack will power Dataview for approximately 10 hours, depending on how many sensors are being used.

Battery state of charge is indicated by the POWER light on the front panel. When the battery is low, this light will flash. The internal battery charge level is also available on the Dataview PC program.

To charge the internal battery pack, connect Dataview to external power by one of the methods indicated below. If the battery is low and external power is applied, the CHARGE light on the front panel will light, indicating the battery is being charged. If the battery is low, the CHARGE light will be on solid, indicating it is being fast charged. Once the battery is partially charged, the CHARGE light will flash on and off indicating it is being trickle charged. This will happen automatically as the battery charges. The battery will be fully charged in nine hours. Leaving external power connected for longer periods will not damage the battery.

External AC Power

The 131-5052 AC Power Adapter (1) is provided for 110/220 V AC operation. To use this adapter, plug the connector in the end of the adapter cable into the POWER connector (3) in the rear of Dataview. Plug the 131-5047 AC Power Cable (2) into the Adapter and into an AC power source. For European 220 VAC power use, use either the 131-0171 Adapter provided, or a 131-6975 European Power Cable . For some countries you may have to cut the connector from the cable and install one that fits your AC Power receptacle. When plugged into AC power, the CHARGE light will come on indicating the batteries are being charged.

External DC Power

data logging, Dataview can be operated on 11 to 40 V DC machine power. Use a 137-0168 External 11 to 40 VDC Power Cable to connect to the machine battery.

Show/hide table

NOTICE
Always connect the red clip lead to the battery positive terminal and the black clip to the frame of the machine only. Do not connect the black lead to the battery negative terminal as this can cause damage to Dataview hardware. When the POWER switch is turned ON, the indicator light should go on. The CHARGE light will also light indicating the internal batteries are being charged.

Powering Dataview From a Vehicle Cigarette Lighter

Dataview may also be powered from a 12 V vehicle cigarette lighter. Use the optional 137-0170 Cigarette Lighter Cable. When plugged into the cigarette lighter, a small red light on the cigarette lighter plug will light, indicating it is obtaining power from the vehicle battery. Plug the other end directly into the Dataview rear POWER connector. When connected, the CHARGE light will light indicating the internal battery is being charged. When the POWER switch is turned ON, the indicator light should go on.

Show/hide table

NOTICE
The 137-0170 Cigarette Lighter Cable. is for 12 VDC operation only. Do not plug it into a 24 V cigarette lighter socket which is found on some Cat machines or the adapter may be damaged.

Operating Dataview

This section of the manual describes how to use the Dataview hardware, and includes an overview of the software, since the hardware and software must be used together. However, a separate Dataview software manual (Dataview User Manual) gives detailed information on using the software.

Using Dataview consists of eight main steps. These steps are listed below and are described in detail in the following paragraphs.

• Connecting Dataview to a PC.

• Installing sensors before starting Dataview.

• Starting the Dataview PC program.

• Using the "Setup" tool to install sensors.

• Using the status tool to view data.

• Displaying real-time data with the strip chart or histogram tools.

• Logging and storing data.

• Saving data on files.

Connecting Dataview to a PC

A standard parallel printer cable can be used to connect Dataview hardware to the PC parallel port. It should be shielded and not over 5.5 m (18.0 ft) in length. A short, 131-5053 Cable , is included with the Dataview group. Connect this cable between the Dataview connector labeled "PC PARALLEL PRINTER PORT" and the PC parallel printer port. If the PC has a small 8 pin connector, instead of the 24 pin, an adapter can be used. This is the only connection between Dataview and the PC.

Installing Sensors Before Starting Dataview

Sensors can be installed in the Dataview hardware before or after turning it ON. If using auto ID cables on some sensors, it is best to install these sensors before starting the Dataview program, because they will be automatically detected and set up when the program is started.

If the user has used Dataview before, and has saved a "GROUP" (a GROUP is a previous setup which was saved to use again), the user will need to know exactly what sensors have been pre-assigned to each input, and make sure that each sensor is in its proper location. To do this, the group list showing what should go in each input is required, or start the program to view the "GROUP" list.

If using Dataview for the first time, determine which sensors you will use by referring to the "Optional Items" section of this manual. There is information about analog sensors and frequency sensors in this section. Locate the sensor information that is needed from the appropriate paragraph. All the sensors listed are available from Caterpillar. The part number and detailed information is shown for each sensor. To determine whether certain sensors are analog or frequency, use the list below or the list on the top label of the Dataview hardware.

Table 29

Sensor Identification
Analog Sensors	Frequency Sensors
Pressure	Speed sensors
Temperature	Hz
Blowby Probe	Duty Cycle
Position Probe	Flow

If the sensor is analog, an auto ID cable is available, which can be installed on the end of the sensor cable, to make setup automatic for that sensor. RTD temperature probes will be automatically detected without an auto ID cable. Plug the analog sensors into channels 1 through 6 and the frequency sensors into channels 7 through 9. If unable to identify if the sensor is analog or frequency, wait until after the "Starting the Dataview PC Program" following paragraph, to identify and install the sensors by using the "Add Channel" pushbutton in the "Setup" tool.

Starting the Dataview PC Program

Communication between the PC and Dataview hardware is essential for using Dataview which communicates with the PC over the parallel printer port. This communication link will automatically be made when the Dataview program is started, if the cable is installed between Dataview and the PC, and that Dataview is turned ON. Follow these steps to start Dataview.

1. Install the Dataview software program on the PC, according to the directions given in the Dataview user manual.

2. Make sure the cable connecting the PC parallel (printer) port is connected to the Dataview hardware parallel port.

3. Turn the Dataview hardware power switch to ON.

4. Position the pointer on the Dataview icon and double click the left mouse button to start the Dataview Program on the PC. As this program is starting, the PC will automatically communicate with the hardware, and a message at the bottom left corner of the screen will indicate whether Dataview is sending data or has stopped. If you start Dataview with a bad communication link, you will have to fix your connection problem (turning on unit, etc.), then try to reconnect.

Note: If Dataview hardware is turned OFF while the PC program is being used, proper communications with the PC will not be established automatically after Dataview is turned ON again. With Dataview ON, exit the PC program and restart it. Dataview will then send data.

5. Once Dataview is connected and communicating, you will be asked to enter machine information in the dialog box, shown below, if it has not been turned off in the default settings.

Show/hide table



Illustration 29	g02562416
Enter machine information dialog box.

Note: The "Enter Machine Information" on dialog box gives a record of what machine is being tested. This information will be used when a report is printed. Select "Cancel" if not entering this information. Select "OK" to accept the entered information and to move to the "Setup" tool screen.

6. The program should now be in the "Setup" tool. If not, select "Setup" on the tool bar at the top of the screen. The buttons on this bar allow selection of the following Dataview tools: Setup, Status, Strip Chart, Histogram, Setup Logger, and View Logger. The function of each selection will be described later.

Using the Setup Tool to Install Sensors

The "Setup" tool is used for telling Dataview what sensors will be used on each channel of the hardware. It is also used to select units of measurement, to check the sensors, to zero the sensor output, and to allow custom naming of each channel. The following illustration displays what the screen looks like.

Illustration 30	g02562476
Setup tool screen layout.

The first time Dataview is started the channel information of this screen (Illustration 30) will be blank, except for analog sensors with auto ID cables and RTD sensors. These sensors will be shown on the corresponding channel that they are hooked up to, and will be ready to use. To use other sensors, install them in an open channel and make a setup, one channel at a time. Locate the name of the sensor that is plugged in by using the "Setup" tool. If the user plugs into an analog sensor channel on the hardware, place the pointer on the matching analog channel number (numbers 1 through 6) in the software, then push the left mouse button to highlight the channel. Double click on the highlighted area, or press the "Edit Channel" push button at the bottom of the screen. The "Define Analog Channel" dialog box appears, displaying a list of available sensors. This dialog box is shown in Illustration 29.

Illustration 31	g02562496
"Define Analog Channel" Dialog Box.

Highlight the desired sensor in the "Sensor Type" list box, by clicking on it. This will assign the sensor to the selected channel. If the sensor name cannot be seen, press the up and down scroll bars at the right of the sensor list. Press "OK" or push "RETURN" to accept the changed or added sensor. Look at the "Output" column heading, in the "Setup" tool, to see if the newly assigned sensor is working properly.

Similar to analog sensors, frequency sensors can be set up by highlighting a frequency channel (numbers 7 through 9) in the "Setup" tool, then pressing the "Edit Channel" pushbutton. When selecting a sensor in the "Define Frequency Channel" dialog box, use the same procedure as in the "Define Analog Channel" dialog box. For some frequency sensors a PPR (Pulses Per Revolution) or a K Factor value will be required. This is described in more detail in the individual measurement sections.

The "Calculated Channel" push button allows you to install calculated channels. These channels are made up of two analog or two frequency channels being added or subtracted. They also display hydraulic horsepower from a flow and a pressure channel. For this procedure, refer to the Dataview User manual.

If a group was not selected during the setup process, the "Setup"tool will be labeled "<Temporary>" at the top of the screen. This means that this particular setup has not been saved as a group. Press the "Save Group" push button to save this group for later use. It will ask for a name to give the group, and it guides the user through the saving process. Saving the group allows it to be used again; so this particular setup does not have top be repeated the next time the Dataview is used.

Testing the Sensors

Before taking measurements with the installed sensors, they should be tested to make sure that they work and are accurate. This is possible because the "Setup" tool shows the output of each sensor. By applying an input to each sensor, you will be able to see if the output is correct. Once they have been checked, they are ready to be installed in the machine for measuring actual data.

Failed Sensors

If a sensor output exceeds its normal operating range, "FAIL" will appear in the output column. Try a different sensor or cable to correct the problem.

Zeroing Pressure Pickups

If a pressure sensor has no pressure applied, but the output is reading a number other than zero, it is possible to zero it. To do this, position the pointer on the appropriate channel to be zeroed and highlight it by pushing the left mouse button. Next, press the "Zero" push button at the bottom of the screen and follow the directions indicated. If the sensor output is more than 5% from zero the sensor cannot be zeroed.

Using the Status Tool to View Data

The "Status" tool is the main display screen of real-time channel values. When the setup is finished, press the "Status" push button from the tool bar. This will open up the "Status" tool. After the previous steps, of installing and testing the sensors, the "Status" screen is ready to use. The machine to be tested may be started at this time. The status of each sensor will be displayed on the "Status" tool, as shown in Illustration 32. The output and names of all channels can be seen in real time here, which means the readings will be updated as they are changing. The "Status" tool has many features with some described in the sections that follow.

Illustration 32	g02562498
"Status" Tool layout.

Zoom In/Zoom Out

The "Zoom In" push button allows the user to display the text and graphics larger on the screen. This enables the user to take readings off the PC from a farther distance. The "Zoom Out" push button returns the "zoomed in" text back to normal size.

Displaying Graphics

The graphics feature allows the user to look at an associated bar graph to analyze the status of the sensors. By pressing the "Show Graphics" push button, the graphs can be viewed that relate to the measurement values. If viewing of the graphics is complete, select the "Hide Graphics" push button.

Note: Many more features are available with this tool. Refer to the Dataview User Manual for more details.

Displaying Real Time Data with the Strip Chart or Histogram Tools

Strip Chart Tool

Using the "Strip Chart" tool allows the user to view strip charts of selected channels in real time, as the measurements are made. This tool is useful for looking for intermittent operation of a machine and oscillation or spikes of a hydraulic system. After selecting the "Strip Chart" push button from the tool bar, the user will be asked to select a data source. Select "Real Time Data - From Hardware". The "Select Graph Channels" dialog box will appear. To select the channels that the user wants to chart, highlight the desired channels in the "Channels Setup" list box, then press the "ADD>>" push button. The channels will be moved into the "Selected Channels" list box. The user can select up to three channels to view. After the channels are selected, press "OK" and to go into the "Strip Chart" tool and view the chart. The diagram in Illustration 33 is an example of a real-time chart showing three channels of real-time data.

In the diagram shown in Illustration 33, all three charts are shown separately. By selecting "Overlay Graphs" on the "Select Graph Channels" screen, all three graphs can be seen on the same chart.

Illustration 33	g02562516
"Real Time Strip Chart" Tool layout.

Note: Refer to the Dataview User Manual to learn about the other options from the "Select Data Source" dialog box. The other two allow the user to see charts of data logs from the PC or from the hardware. The real-time option, that has been chosen, allows the user to see charts of the desired channels while they are operating. Also, if more than one channel is charted, they can be overlaid to check for differences between the traces.

Histogram Tool

The "Histogram" tool allows the user to view a histogram bar chart for one selected channel, showing the amount of time that the channel input was in various ranges. This allows the user to look for potential problems in a machine, by determining if the amount of time spent at various measurements, while the machine is being operated, is appropriate. The histogram also allows the user to see if operation is normal or excessive, and to look for problems.

Illustration 34	g02562536
"Histogram" Tool layout.

The steps involved in preparing a real-time histogram chart for viewing, is the same as the steps for the "Strip Chart Tool" section, except that only one channel can be chosen for a histogram. Once the user has selected the desired channel to display in the histogram, from the "Select Graph Channels" dialog box, the "Histogram" tool will be displayed. To begin the charting of the histogram, press the "Start" push button.

Data Logging and Storing Data

Setup Logger Tool

The "Setup Logger" allows measurements made by Dataview to be recorded. This allows the user to measure and see intermittent problems that cannot be observed as they happen, because they may be too fast or seldom occur. Before Dataview can log data, the logger must be set up. The logger setup procedure will define the channels, logging time before and after trigger, sampling rate, and auto trigger. Dataview will show the current output of each sensor on the "Setup Logger" tool. The following illustration displays the "Setup Logger".

Illustration 35	g02562556
"Setup Logger" tool layout.

To start this tool, simply press the "Setup Logger" push button on the screen. This goes directly to the Setup Logger. At the screen, select the channels to set up for logging, by clicking the box next to the desired channel. Choosing the channel will put an "X" in the box and the "Logger Setup" push button at the bottom of the screen will become enabled. Press this push button to do the logger setup. The "Setup Data Logger" dialog box will be displayed. Within this screen, assign the "Sample Rate", the" Log Time Before and After the Trigger", and if desired, set up the "Auto Trigger Setup".

The "Auto Trigger Setup" allows set up of an automatic trigger for logging data. After the data logger setup is complete, press the "Send Configuration" push button and the program will return to the main "Setup Logger" screen. Notice the "Manual Trigger" pushbutton has become enabled.

If an "Auto Trigger Setup" is required, both the "Manual Trigger" and "Auto Trigger" pushbuttons become enabled. To begin the actual triggering, press either the "Manual Logger" or "Auto Logger" push-buttons, depending on the required setup. The "Logging Status" display area will keep you updated on the logging process. If the "Auto Trigger " is chosen, it will begin logging once the trigger point is reached. At that point, the status of the logging in the "Logging Status" display area can be seen, similar to choosing the "Manual Trigger" push button. This completes the logging data set up process.

Note: Be sure that a memory card is installed in the rear slot of Dataview, before you set up to log data.

View Logger Tool

To view the data that has just been logged, go into the "View Logger" screen. This tool allows viewing of log data captured by the Dataview hardware on the PC. The user can either retrieve the log from the Dataview hardware or from a saved log file on the PC.

To view the data logged in the Setup Logger tool, first press the "View Logger" pushbutton. The Select Data Source dialog box will be displayed with the choice to select a logged data file from the hardware or from the PC. Highlight the "Logged Data File - On Hardware" and press "OK". The "Log Select" dialog box will be displayed with a list of data logs in the "Logs" list box. The program will default to highlight the latest log that was recorded, which in this case is the data recorded in the "Setup Logger" tool. Press the "OK" push button, since the correct log is highlighted. The "View Logger" screen will appear. This screen displays a series of VCR or tape recorder-style push-buttons. Dataview allows the user to stop, rewind, and play log data through these push-buttons. Refer to the User Manual for detailed instructions on the function of these different push-buttons. Along with VCR-style functions, the font size can be increased, data can be shown in graphics form, and data can be printed to a report document. Refer to the User Manual for more information on these additional functions.

"Logged Data Strip Chart" Tool layout.

One of the main and most convenient features of the logged data "Strip Chart" tool, is the zooming feature. This tool allows the user to zoom in on a smaller range of the graph than what is first displayed when the user enters in this screen.

To zoom in on a smaller range of the graph, press the right push button in the left cursor area. A vertical cursor appears one place to the right of where it started, on all three of the graphs. Then, press the left push button in the right cursor area, a different vertical cursor appear one place to the left of where it started, on all three graphs.

To move either cursor left or right one position, press either the left or right push-buttons. Once the desired viewing range is within the two cursors, press the "Zoom In" push button. The graphs will adjust to display the new, smaller range that has been selected. To view an even smaller range, repeat the same steps with the cursors. To zoom out to the original view, press the "Zoom Out" push button.

Note: There is a simpler method for positioning the cursors. Place the arrow at the desired position for the left cursor, then push the left mouse button. Next, place the arrow at the desired position for the right cursor, then push the right mouse button. Press on the "Zoom In" push button to see the smaller range. Also note, many more features are available with this tool. Refer to the Dataview User Manual for more details.

Saving Data on Files

File Structure

A file is a place to store information that has been acquired through Dataview. A file can contain several documents. A document can either be a report or a log, depending on what is stored in the log.

A report document is created whenever a file is printed from the "Status", "Strip Chart", "Histogram", or "View Logger" tools. A report document will include a list of the current setup and the status of the tool at the time the file was printed.

A log document is created when a log is downloaded from the Dataview hardware. Once a log has been downloaded to a document it can be viewed without being connected to the Dataview hardware.

To view and manipulate files and documents from Dataview, choose the "File Management" option from under the "File" menu. The "File Management" dialog box will appear showing the names of the current files on the computer. Select a file by clicking the mouse on the desired file, this will bring up a list of documents that are in that file. If a document is selected, a description of that document will be displayed. Use the buttons on the right side of the screen to manipulate the file or document that has been selected. Illustration 38 displays the "File Management" dialog box.

Measuring Frequency (Hz) and % Duty Cycle with Dataview

Show/hide table

NOTICE
Do not apply over 40 V AC or DC maximum to any Dataview channel input. The 9U-7505 High Voltage Adapter must be used for all voltages over 40 V and up to 600 V maximum. Use the adapter only on the frequency channels for measuring frequency or %duty cycle. It plugs directly into any frequency channel (channels 7, 8, or 9).

Dataview contains a frequency (Hz) measurement function and a "% Duty Cycle Measurement" function for the frequency channels. The "Hz" function can be used to measure sensor output frequency or AC power and generator set frequency for any frequency or pulse signal that is within the input specification range. The % duty cycle reading is useful to read the output measurement of Cat pulse width modulated sensors used on electronic controls. However, a special adapter cable must be used because the output of these sensors is offset from ground and does not go to zero V. Contact CSTG for status of this cable. The % duty cycle values for these sensors can be found in the service manual on the product they are used with.

There are four different methods of connecting the signals to Dataview for measuring Hz and % duty cycle. These methods are described below.

Table 30

Methods of Connecting the Signals to Dataview for Measuring Hz and % Duty Cycle
Frequency Measurement Method	Voltage Range	Required Current Flowing in Circuit to be Measured
Direct Input to Frequency Inputs	0.1 to 40 V	Does Not Apply
Using 9U-7505 High Voltage Adapter	0.2 to 600 V	Does Not Apply
6V-4960 AC Current Probe	110 to 650 VAC	1 to 1000 Amps
9U-5795 AC/DC Current Probe	110 to 660 VAC	80 to 700 Amps

Measurement Instructions

For voltages less than 40 V, connect the signal to be measured directly to a frequency channel input. Use an existing cable if it is available, or use the diagram in Illustration 39 to make a cable to connect the signal to the frequency input. If the signal voltage will be more than 0.2 V, but less than 600 V, the 9U-7505 High Voltage Adapter can be used with test leads.

Illustration 39	g02562637
Pin 1, Shield. Pin 2, Input Signal. Pin 3, Ground. Pin 4, No connection. Pin 55 V DC (Photohead Power).

Once the connection has been made, start the Dataview program on the PC and select the desired channel on the "Setup" tool. Double click on that channel and choose either Frequency or % duty cycle from the "Define Channel" chart. It is not necessary to set the PPR since this value is automatically set to the proper value. The value can be read on either the "Setup" or "Status" tool.

Using the 9U-7505 High Voltage Adapter to Measure Hz

Illustration 40	g02562638
9U-7505 High Voltage Adapter .

Connect the cable coming from the 9U-7505 High Voltage Adapter to frequency channel 7, 8, or 9. The 6V-2198 Extension Cable can be used, if desired. Insert the 6V-7072 Test Leads into the red and black input jacks in the high voltage adapter. Slip the alligator clips onto the test probes, if desired. Make sure the voltage to the circuit being tested is turned OFF, then connect the alligator clips to the circuit. Measure the frequency as described on the previous page.

Using the 6V-4960 AC Current Probe to Measure Hz

This measurement method provides a non-contact method of measuring frequency. The Cat 6V-4960 Probe is clamped over the wire which has the AC signal flowing through it. However, the wire being measured must have at least 1 amp of current flowing through it for Dataview to give a reading.

Illustration 41	g02562639
6V-4960 AC Current Probe to Measure Hz.

Connect the 9U-7505 High Voltage Adapter to frequency channels 7, 8, or 9 as described earlier in this section. Connect the 6V-6014 Cable to the 6V-4960 AC Current Probe . Connect the banana plugs on the other end of the cable to the banana jacks on the high voltage adapter. An alternate method is to use a 9U-5265 Adapter and 9U-7506 Magnetic Adapter Cable to connect directly to Dataview without using the high voltage adapter. Squeeze the handles of the probe together and place them over a wire carrying the current whose frequency is to be measured. Read the frequency as described.

Using the 9U-5795 AC/DC Current Probe to Measure Hz

This probe provides another method of making non-contact measurements of frequency, however at least 80 amps is required in the circuit being measured for Dataview to obtain a reading. This will limit the use to AC generator set use.

Illustration 42	g02562640
9U-5795 AC/DC Current Probe to measure Hz.

Connect the 1U-7505 High Voltage Adapter to frequency channels 7, 8, or 9 and connect the banana plugs on the current probe into the high voltage adapter. Refer to the Tool Operating Manual on the 9U-5795 and turn on the current probe. Connect the probe over a wire carrying the current whose frequency is to be measured. Take the reading as described in the previous section.

Using Dataview to Measure Engine Set Point

Dataview contains an engine set point feature that can be used for measurement of the set point rpm of Cat diesel engines which have an external mechanical fuel injection pump with a rack contact on it. These are usually older Cat engines. The set point (formerly called the balance point) is 20 rpm more than the balance point of the engine. Because of this, 20 rpm must always be subtracted from the measured set point to find the balance point rpm listed for the engine. This measurement was formerly measured using either 9U-7401 Multitach II , or the 6V-4060 Engine Set Point Indicator and a 6V-2100 Multitach . For a detailed description of measuring engine set point and a full explanation of set point, balance point, and full load rpm, refer to the Special Instruction, SEHS7931, for the 6V-4060 Engine Set Point Indicator .

Two set point inputs are provided, CH7 and CH8. The CH7 set point input works with frequency channel 7 for rpm measurement, and CH8 works with channel 8. An 8T-5111 Adapter Cable and a 1P-7446 Rack Cable are both required to connect the set point inputs to the engine. Any type of rpm sensor can be used. To measure set point, set up the rpm in the corresponding channel, and turn on the set point display by double clicking the rpm channel to bring up the "Define Frequency Channel" dialog box. Select the "Set Point Attached" box and the "Set Point" display will always be shown with that frequency channel display. Measure set point in the normal manner described in the Special Instruction, SEHS7931. The set point rpm will be held on the display when set point is reached. To take another reading click the arrow on "RESET" and measure set point again.

Measuring Fuel Flow with Dataview

Dataview can be used to measure fuel flow using the fuel meters from the Cat 1U-5430, 1U-5440, or 1U-5450 Fuel Flow Monitor Arrangements. A 1U-9500 Fuel Flow Communicator is also required. Since the output of the Cat flowmeters is a nonstandard digital current loop signal, the fuel flow communicator is required to convert this output signal into a frequency which can be measured by Dataview.

Use these steps to read fuel flow with Dataview:

1. Refer to the Special Instruction, SEHS8874, "Using the Cat Fuel Flow Monitor System" for installation of the flowmeters on the engine to be measured. The 8T-9300 Fuel Flow Monitor can be used during installation to verify proper operation.

2. Replace the 8T-9300 Fuel Flow Monitor with the 1U-9500 Communicator . Refer to Tool Operating Manual, NEHS0623 for more information on the communicator. Connect the fuel flowmeters to the communicator using the standard cables provided with the meters. If only one meter is used, it must be connected in the SUPPLY METER input. Connect the OUTPUT connector on the communicator to Dataview frequency channels 7, 8, or 9 using a 6V-2198 Extension Cable. Connect the EXTERNAL POWER SUPPLY connector on the communicator to the 8T-9280 Power Supply , plug it in and turn it ON. The communicator will start sending fuel flow information to Dataview.

3. Turn on the Dataview hardware and start the Dataview PC program. From the "Setup" tool, select the channel connected to the communicator and double click on it to bring up the "Define Frequency Channel" dialog box. Select Cat fuel flowmeters from the list. Set the units as desired. It is not necessary to set the PPR value.

4. Select the "Status" tool to view the fuel flow rate. Once the engine is started the flow rate should appear in the channel connected to the communicator. Operation of the communicator is automatic. If a supply and return meter are connected to the communicator, Dataview will show the fuel burn rate of the engine. If only one meter is connected to the communicator in the SUPPLY METER input the flow rate will be either supply only or return rate only depending on which is plugged into this input. For single meter operation, a meter must not be plugged into the RETURN METER input. If changing from one meter to two meter operation, the communicator power supply must be turned OFF, then back ON to reset it.

NOTICE
Fuel temperature cannot be measured at the flowmeters with Dataview. A separate RTD temperature sensor must be used in an analog channel.

Maintenance

Replacing the Internal Battery

Dataview has an internal nickel metal hydride rechargeable battery. When this battery no longer gives sufficient operating time, it can be replaced with a Varta C526F, 7.2V 2400 mAh battery. Contact CSTG for availability of this battery.

Follow these instructions to replace the battery.

1. Disconnect all cables from Dataview and turn the power switch OFF. Turn the unit upside down and remove all screws in the bottom panel. Remove the bottom panel and the battery will be visible. Loosen the screws on the battery holder (on the end of the battery without wires). Lift the battery and remove it.

2. Install a new battery so the side with the groove in it is visible. Press the battery holder bracket back and insert the battery into the holder with the contact end in first. Press the battery down into place. Push the clip against the battery and tighten the screws.

3. Replace the rear cover and install a few screws. Do not over tighten the cover screws or the threads will be stripped. These screws have very few threads can be stripped very easily. Turn the POWER switch ON. If the ON light is on, the battery has been installed properly. It may be necessary to charge the battery first to get the light to come ON. If the light will not light, reinstall the battery to make sure it is making contact properly. Once the light goes on, the rest of the screws can be installed.
