  • Page 13: Panel Mounting

    Panel Mounting You can easily mount a Model 4040 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 4040, DO NOT REMOVE THE FRONT BEZEL. Simply unscrew the two rear-panel CLAMP SCREWS and slide the CLAMP SLIDES rearwards out of their grooves.

  • Page 15: Standard Logic Configuration

    Standard Logic Configuration Your 4040 provides eight logic input/output bits in open-collector, negative-true form, where the "Logic 1" state is defined as nominal 0 V-DC and "Logic 0" as nominal +5 V-DC. The standard logic I/O configuration is shown in Fig. 4, below, with reference to the 10-terminal Logic I/O Connector on the rear of the 4040.

  • Page 17: Using The Front-Panel Setup Buttons

    Using the Front-Panel Setup Buttons Study this manual section carefully to familiarize yourself with the general operation of your 4040's front-panel buttons when they are in "SETUP" mode. Specific setup parameters—such as "HIGH END- POINT (HEP)", "FILTER (FIL)," "LCD," etc.—are explained in detail in Section 2.
  • Page 18 Using the Front-Panel Setup Buttons Each of the six buttons will now assume its "SETUP" function, as designated by the actual button label (for each button's "RUN- TIME" function, see Section 3.) The small mnemonic display under the 4040's unit legends will alternately read "DIS" and the number of the channel that was on display when you pushed the SETUP button.
  • Page 19 Using the Front-Panel Setup Buttons —at which point you can, if desired, move to any other channel via the UP/DOWN ARROW buttons, as above. 3. Stepping Through a Channel's Parameter List A given channel's configuration sequence includes the parameters listed on the next page. These will appear as mnemonics under the unit-legend display.
  • Page 20 Using the Front-Panel Setup Buttons To move to the next parameter in sequence, STEP PRESS THE BUTTON As each parameter appears, you have the option of leaving it as it is and stepping to the next one by again pressing STEP, or of modifying its value by means of the "ARROW"...
  • Page 21 Using the Front-Panel Setup Buttons In the negative realm , these buttons seem at first glance to function backwards. 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

    Low Battery Warning The 4040 is equipped with an internal 3-V lithium battery. This battery is necessary to maintain the instrument's DATA RAM and to retain factory-entered analog alignment values required for accurate calibration. Data retention is guaranteed down to a battery level of 2.2 V-DC.

  • Page 24: Transducer Cabling

    Transducer Cabling The Model 4040's Analog Input Board mates with Daytronic CONDI- TIONER CONNECTOR No. 60322, which allows direct solder-terminal attachment of cable leads. The connector's internal solder terminals are labelled 1 through 10 and A through L. Pin assignments are given in the table on the next page.

The capacitor is here in series with the +SIGNAL input and allows only AC to pass. Suppression of High-Frequency Noise—False triggering can some- times occur, especially at the low-frequency input range, because of stray pickup of frequencies outside the common-mode range.

  • Page 28: Powerup

    Powerup ---------- PLEASE NOTE ---------- EVERY TIME YOU POWERUP YOUR MODEL 4040, ALLOW A NOMINAL 15 SECONDS FOR VALID DATA AND SETUP VALUES TO BE ESTABLISHED. ALSO NOTE: Since setup entries are automatically saved to nonvolatile memory, your 4040 will always powerup to the same setup and display configuration that existed when it was last powered down.
  • Page 29 Powerup The 7.5-foot, three-conductor power cord supplied with the 4040 plugs into the rear AC POWER CONNECTOR. The offset pin on the power connector is ground. THE INSTRUMENT MUST BE PROPERLY GROUNDED. To safely operate from a two-contact outlet, use a 3- prong-to-2-prong adaptor and connect the green pigtail on the adaptor to earth ground.

Then press the STEP button to display Channel 2's "F1" parameter. Apply a second accurately known value of input loading—a value from 80% to 100% of the transducer's nominal full-scale rating.

  • Page 34: Setting Channel Filter

    Setting Channel Filter In addition to the normal-mode analog filtering applied to the Model 4040's "live" input channel (No. 2), 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

    Scaling the Bargraph Display After calibrating your 4040's "live" input channel (No. 2), you should set the high and low endpoints for the individual BARGRAPH display of 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 4040 data channels listed in Section 1.d.
  • Page 36 Scaling the Bargraph Display less than the "HEP" value. At least 51 units (absolute count) must separate the HEP and LEP values. NOTE, however, that the 4040's front panel furnishes a "truncated" numeric display of the two endpoint values of the currently displayed bargraph (see Fig.

  • Page 37: Defining Limit Zones

    Defining Limit Zones Once you have set the endpoints of the respective bargraph display for Channel 5, you can define seven discrete limit zones for the bargraph, as shown in Fig. 8: "BELOW BARGRAPH" ZONE (less than LEP); LOWER "DANGER" ZONE (LEP to LLL); LOWER "CAUTION" ZONE (LLL to LOL);...
