    Panel Mounting You can easily mount a Model 4030 in your own precut panel. Cutout dimensions for a panel-mounted unit are standard DIN (see Fig. 3); panel thickness should not exceed 6 mm (0.24 in). When mounting a 4030, DO NOT REMOVE THE FRONT BEZEL.

  • Page 17: Using The Front-Panel Setup Buttons

    The 4030 provides instant visual feedback for its front-panel buttons. Thus, pressing any button will light the green ON LINE indicator. This indicator is located in the lower right-hand corner of the 4030 front panel (see Fig. 1). It will remain lit as long as the button is pressed.
  • Page 18 (for each button's "RUN- TIME" function, see Section 3.) The small mnemonic display under the 4030's unit legends will alternately read "DIS" and the number of the channel that was on display when you pushed the SETUP button.

Thus, if the displayed parameter is preceded by a minus sign, then "increasing" the active digit by "1"—as a result of pressing the UP ARROW button—means decreasing that digit's absolute value by "1."...
  • Page 22 Using the Front-Panel Setup Buttons NOTE: The above procedure will change the original values of one or more digits to the right of the most significant digit , except in the case where they are all originally zero. Therefore, you will most likely have to go back and reset these digits, using the LEFT ARROW and UP/DOWN ARROW buttons as explained in Step 5.

  • Page 23: Low Battery Warning

    Data retention is guaranteed down to a battery level of 2.2 V-DC. Under normal usage, the battery should last about five years. The 4030 will check its battery every time the unit is turned on. If on powerup, the battery is found to be below 3.0 V-DC, the front-panel LCD will display a warning of "LO bat."...

  • Page 28: Powerup

    1. AC Operation This is "normal" operation for the Model 4030. A 4030 can operate from a line voltage of either 90-135 or 180-270 V-AC (47-63 Hz; 35 W maximum). The VOLTAGE SELECTOR SWITCH is located on the rear panel (see Fig. 2(a)).

  • Page 29: Dc Operation

    (isolators, regulators, uninterruptible power supplies, etc.). 2. DC Operation When ordered with the "V" ( Vehicle ) option, a 4030 may be operated from nominal 12 V-DC (30 W maximum). The actual tolerance range is 11-18 V-DC.
  • Page 30 CAUSE OF OVERLOAD BEFORE REACTIVATING THE INSTRUMENT. ----------IMPORTANT---------- In all cases, the "ground" terminal of the 4030 DC CONNEC- TOR should be connected either to the negative terminal of the vehicle battery or directly to the vehicle chassis. IT SHOULD NEVER BE LEFT UNCONNECTED. ALSO, TO MINIMIZE NOISE PICKUP, THE GROUND LEAD SHOULD BE AS SHORT AS POSSIBLE.

  • Page 31: Adjusting Lcd Viewing Angle

    Adjusting LCD Viewing Angle You can easily optimize your 4030's LCD DIGITAL DISPLAY for your particular viewing angle . Following the procedure given in Section 1.f, above, press the instrument's front-panel SETUP key, and then "step" to the "LCD" parameter (the letters "LCd" should appear in the digital display, to indicate that the instrument is in "LCD adjustment"...

  • Page 32: Selecting A Channel For Display

    NOTE: As explained in Section 3, you can always use the LIVE DISPLAY button—when not in "SETUP MODE"—to call to display your 4030's Channel 5 ("tared" analog input). You can also use the MAX/MIN/MAX-MIN STEP button to cycle sequentially through...

  • Page 33: Channel Calibration

    Channel 1 ("LIVE" ANALOG INPUT). All other channels derive their readings from Channel 1. In general terms, you will normally calibrate your 4030's Channel 1 by commanding its microprocessor to compute and store two constant values: a ZERO OFFSET (based on setup entry "F0") and a SCALING FACTOR (based on entry "F1").

  • Page 34: Setting Channel Filters

    Setting Channel Filters In addition to the normal-mode analog filtering applied to the Model 4030's "live" input channel (No. 1), digital filtering is also provided, with smoothing constants selectable via the front panel. The effect of the digital filter is to remove small unwanted dynamic signal components, while allowing large-scale fluctuations to pass unaffected.

  • Page 35: Scaling The Bargraph Display

    Channel 5 ("LIVE" INPUT WITH TARE), using the procedure given below. This same procedure may be used to scale the bargraph dis- play of any of the other 4030 data channels listed in Section 1.d. For the relation of BARGRAPH endpoint values to the other four limit-zone- defining parameters, see Fig.

  • Page 36: Defining Limit Zones

    Scaling the Bargraph Display NOTE, however, that the 4030's front panel furnishes a "truncated" numeric display of the two endpoint values of the currently displayed bargraph (see Fig. 1). That is, the endpoint numbers will appear with all but the first two significant digits converted to "0." THE RESULTING PRECISION OF THE DISPLAYED "LEP"...

Logic I/O Connections As shown in Fig. 4, the 4030's rear Logic I/O Connector has eight numbered LOGIC I/O terminals, plus a +5-V (LOGIC REFERENCE) terminal and a "GD" (GROUND) terminal. The "standard" 4030 configuration calls for logic OUTPUTS from Terminals 0 through 6.

  • Page 49: Appendix D: Channel Linearization

    App. D Channel Linearization When your 4030's "live" input channel (No. 1) is derived from a nonlinear transducer, you may calibrate it by means of one of the instrument's eight internal "look-up" tables. The purpose of such a table is to linearize the signal in question, to "bend" its characteristic curves to achieve at least approximately "straight-line"...
  • Page 50 App. D Channel Linearization LNS = 7 Measured Output Fig. 14 Typical Linearization Curve, with Seven Segments Using the "ARROW" buttons, enter for "F0" the exact minimum load value established in Step 5, expressed in appropriate engineering units. Press the STEP button again to display Channel 1's "F1" para- meter (this is the value of the endpoint of the first linearization segment).
  • Page 51 , you should enter all LINEARIZATION POINTS expressed to the nearest hundredth of an inch (e.g., "1.00"). The 4030's display of any channel based on Channel 1 will then reflect this precision. 11. Continue to enter as many LINEARIZATION POINTS as you specified in the original LNS entry (Step 3, above).

  • Page 52: Appendix E: Changing The Battery

    App. E Changing the Battery If, on powerup, your 4030 displays the "LO bat" warning, you should take the following steps to replace the battery (READ ALL OF THESE DIRECTIONS COMPLETELY BEFORE YOU BEGIN): If possible, offload your 4030's present configuration data to disk...
