  • Page 5: General Overview

    GENERAL OVERVIEW The ACT-3X digital panel meter is an extremely versatile instrument. The user has complete control of the unit configuration. Power may be either 115 - 230 Vac (50/60 Hz), or optionally, 12 Vdc or 24 Vdc. Input signals are accepted (on Channel 1) from optical, proximity, magnetic, infrared or laser sensors, or direct TTL or external AC sources.

    All connections are via the rear panel of the instrument – power, sensors, alarms, analog output, and communication. The rear panel is shown below and may vary slightly depending on what options are in the unit. Figure 2 ACT-3X Rear panel with Analog Output and USB Option 2.3.1 Power Connections Power to the unit is connected to the terminals under the sections labeled POWER on the rear panel.

    NOTE: Sensor shields may be attached to input common (COM) if a ground point is not available. Figure 3 Sensor Connections 2.3.3 Analog Output The Analog Output is an option. The Output option is marked on the back of the unit to the right of the connector – refer to Figure 2.3.3.1 Current Output...

  • Page 8: Serial Communications

    2.3.7 Serial Communications There are three serial communication options – Ethernet, USB and RS232. The Ethernet option will have a standard RJ45 connector, the USB option will have a type B female connector, and the RS232 option will have a male DB9 connector on the rear panel.

  • Page 10: Totalizing Mode

    Alarm Limits The ACT-3X has two independent alarm set points, referred to as LIMIT 1 and LIMIT 2 (Set 1 and Set 2 on the menu). These limits are fully programmable by the user (unless the write protect option has been set). The limits may be set as high or low with an option of low limit lockout, latching or non-latching at any value.

  • Page 11: Latching Vs. Non-Latching Limits

    Analog (AO) and Current (IO) Output The ACT-3X has options for voltage (0 to 5Vdc) or current (4 to 20mA) outputs. The analog outputs are derived from a 15-bit digital to analog converter. This means that the output voltage (or current) changes in steps.

  • Page 12: Throughput

    Throughput Throughput is a measure of how fast the instrument processes data. The rate at which the instrument acquires data is a function of the ―Gate Time‖ and the input frequency. The instrument gets a start pulse then it continues to get pulses until the Gate Time elapses.

    Stop sending display data Unit stops sending display data Send last calculated reading This value is changed as fast as the throughput of the ACT unlike the @D0 command that gives the last displayed value which only changes up to 2 times per second. In the Rate of Change (ROC) mode this command will give the last RPM measured.

    For use with units ordered with standard Serial Communications, phone plug. Enables the user to program the ACT-3X using a PC with USB connection. The software also allows remote monitoring of the RPM using a graphic display or an Excel spreadsheet.

  • Page 20: Appendix A - Scaling The Act For Engineering Displays

    APPENDIX A - SCALING THE ACT FOR ENGINEERING DISPLAYS The SCALE Mode must be used to display RPM in applications where there is more than one pulse per revolution. Below describes how to use this mode and other applications that need to be scaled. When using the scaling function of the ACT Tachometer it is possible to multiply the input signal by any value from 0.0001 to 99,999 making it possible to display the actual output in virtually any format.

  • Page 21: Appendix B - Useful Conversions

    Suppose we have wheel of d inches in diameter. This wheel turns the tire on a motor vehicle. We get one pulse into the tachometer for each revolution of the drive wheel. We want the display in miles per hour. We ignore slip. NOTE: For more than one pulse per revolution, simply divide the scale factor you get for one pulse by the number of actual pulses per revolution.

  • Page 22: Appendix C - Using The Single Event Capture Mode

    APPENDIX C – USING THE SINGLE EVENT CAPTURE MODE This is to how to calculate a scale factor and to show sources of measurement error. In this example, the distance between sensors is 1 inch and we want the readings displayed in Miles Per Hour (MPH). The fastest measurement we intend to make is 130 MPH.

  • Page 23: Appendix D - Setting Up The Ethernet Interface

    APPENDIX D – SETTING UP THE ETHERNET INTERFACE Connect an Ethernet cable from the ACT-3X device to your network. Note: The device MUST be connected to the same network as the computer on which you are going to run this setup.

    APPENDIX E – MENU OVERVIEW For more detail, refer to Section 5.0. SET - ENTER DATA: Press the SET button and use the buttons to set the required value. Press RECALL to exit up one level without making a change or press SET to make the change. The edit buttons function as follows: RESET - changes the digit being edited (blinking digit)
