5.3 Function Input Pins 5.3.1 Overview To use a Function Input pin (9, 10, 11 or 21), connect it to the DGND (pin 19) momentarily. This can be accomplished by a push button switch, relay contact closure, or PLC output. Usually, the Function Input pins perform the default actions described in the “System Connector Pinout”. However, a SensoCode program running on a Mathematics Virtual Channel may replace these default actions. Consult the System Calibration Sheet included with your instrument for details. 5.
Figure 5-2: Open-Collector Output Example 6.0 SYSTEM MENU 6.1 Overview The system menu allows you to examine and change settings that affect the chassis of the DFI instrument. You can view the internal software revision and the instrument’s configuration (i.e. what types of cards are installed in each channel). Detailed instructions on operating the DFI instrument in the SETUP Menu mode can be found in “SETUP Menu mode. A diagram of all menus is located in the “Setup Menu Reference” in Chapter 18. 6.
Installing a channel will cause it to use the “default” or “empty” configuration information for that channel. Any calibration data, SensoCode mathematics programs, display setup, or other information will be erased to default values! All other channels are unaffected. Input or Output Channel Installation Procedure Before installing an Input or Output card, make certain that you know the “card type” (a two-digit hexadecimal number) of the card you wish to install.
12. If the installation was successful, “DONE” will be displayed. If the installation failed, you will see one of the following messages: • “SYSTEM IS FULL”: There are no unused channels available in the instrument. • “WON’T INSTALL”: The Output Relay card type you selected to install does not match the next available set of Limits. For example, the Limit 09-12 card type will not installed unless the Limit 05-08 card type has been installed. • “ERROR 28 ON CH.
7.2 Wiring The System connector on the instrument’s rear panel is used, among other things, for serial communications. See “System Connector”, Chapter 5, for wiring information. All of the serial communications pins on the 25-pin System connector have 500V of electrical isolation from all other pins and connectors on the instrument. Additionally, all serial communications pins are protected against electrostatic discharge (ESD). 7.3 Communications Protocol 7.3.1 RS-232 vs.
7.4.6 TRANSMIT TEST Menu Item When this menu item is selected, the instrument immediately transmits the message “ADDRESS nn TEST” where “nn” is the two-character address of the instrument. Then the message “MESSAGE SENT” is shown on the display.

It is available only with the Shunt Calibration and mV/V Calibration types. ZERO SCALE VALUE Menu Item The transducer’s zero-scale output in engineering units, which is usually zero.
KNOWN POINT x/y Menu Items This enters the engineering units for the known-load calibration points. These points must match the actual loads that you will apply to the instrument during calibration. The number of calibrations points depends on the CALIBRATION TYPE. When using the 2-Point Known Load Calibration type, the following menu items are available: • “KNOWN POINT 1/2”: point 1 of 2, usually 0% of the transducer’s full-scale capacity.
• The display will read WORKING, then APPLY 01000 UNIT (where 01000 and UNIT are previously entered as KNOWN POINT 2/2 and DISPLAY.UNITS). When you have applied this load to the transducer, press [ENTER]. • Upon completion, the display will indicate DONE and the instrument will return to the RUN mode.
If the DAC is set-up to be driven by its own channel’s tracking value, the Analog Output will have the frequency response specified by the channel’s FREQ.ESPONSE menu item. Otherwise, the Analog Output will operate more slowly. DAC.ZERO-SCALE Menu Item This specifies what value, in engineering units, corresponds to zero output on the Analog Output. “Zero output” might be 0 Volts, 2.5. Volts, 5 Volts, 4 mA or 12 mA depending on if the channel has a voltage or current output and how it is configured.
• “YES” will allow a newly detected Signature Module to update the Analog Output settings. • “NO” will now allow automatic updating of the Analog Output settings. 10.5.9 DIAGNOSTICS Sub-Menu DAC FULL SCALE Menu Item When this menu item is selected, the Analog Output of the channel is forced to its zero-scale output, then DAC UPDATED is displayed. This is useful when calibrating or trimming the readout connected to the Analog Output.
10.6.3 Output Selection Jumpers located on the channel’s circuit board determine what outputs are generated when the value selected to drive the Analog Output (from the DAC.CHANNEL and DAC.SOURCE menu items) equals the DAC.FULL SCALE and DAC.ZERO SCALE settings. Figure 10-3: Digital-to-Analog Output Jumper Locations DAC.ZERO SCALE Output DAC.
Analog Output Incorrect Make certain of the type of Analog Output (voltage or current) that the channel is equipped with; see “Identifying the Output Type”. Use the DIAGNOSTICS-DAC FULL SCALE and DIAGNOSTICS-DAC ZERO SCALE menu items to force the Analog Output to a known output. Then, adjust your readout device panel meter, PLC or data acquisition system to match. Check the output selection jumpers; see “Output Selection”.
11.2 Wiring Connect your transducer to an AC/AC-LVDT Input channel by wiring it to the 12-pin connector of that channel. The System Calibration Sheet that shipped with the instrument describes which cards are installed in each channel. The pin-out for this connector is shown on the following table.
Step 4: Determine the LVDT’s electrical null point, then physically mount it. The electrical null is the armature position that produces the least electrical output. Once this point has been determined, the transducer is physically clamped into position. See “Electrical Null and Transducer Mounting” in Section 11.6. Step 5: Perform the calibration. Using the CALIBRATE menu item starts the calibration process. You will be prompted to apply displacements to the transducer as required. 11.

This menu item doesn’t change the mathematical scaling of the channel’s values; that can be changed by altering the “CALIBRATION DATA-KNOWN POINT X/Y” menu items and then performing a re-calibration. When a character position is flashing press the [UP] or [DOWN] button to change the character. Press [ENTER] to advance to the next character. DISPLAY.AVERAGE Menu Item Controls the speed with which the channel’s display values will update.
KNOWN POINT x/y Menu Items This enters the engineering units for the know-displacement calibration points. These points must match the actual displacements that you will apply to the transducer during calibration. The number of calibrations points depends on the CALIBRATION TYPE. When using the 2-Point Known Displacement Calibration type, the following menu items are available: • “KNOWN POINT 1/2”: point 1 of 2, usually 0% of the transducer’s full-scale capacity.
• The display will read WORKING, then APPLY 01000 UNIT (where 01000 and UNIT are previously entered as KNOWN POINT 3/3 and DISPLAY.UNITS). When you have applied this displacement to the transducer, press [ENTER]. • Upon completion, the display will indicate DONE and the instrument will return to the RUN mode.
11.5.8 DIAGNOSTICS Sub-Menu DAC FULL SCALE Menu Item When this menu item is selected, the Analog Output of the channel is forced to its full-scale output, then DAC UPDATED is displayed. This is useful when calibrating or trimming the readout connected to the Analog Output. DAC ZERO SCALE Menu Item When this menu item is selected, the Analog Output of the channel is forced to its zero-scale output, then DAC UPDATED is displayed.
Step 3: Move the LVDT’s armature to the position that displays the lowest value of raw analog-to-digital converter readings (i.e. a number close to 00.000%). This is the LVDT’s electrical null. Step 4: Firmly clamp down the LVDT’s body. Step 5: Move the LVDT’s armature to roughly the position you wish to define as “positive full scale”.
11.8 Troubleshooting 11.8.1 Error Messages See “Error Messages” in Chapter 17 for information relating to error messages. 11.8.2 Common Problems and Solutions Erratic Display Check electrical connections for continuity and the transducer’s wiring code from its Certificate of Calibration. Make sure that the displacement on the transducer is constant. Check the input to the (+)Signal (“+SIG”) and (-)Signal (“-SIG”) pins with am RMS voltmeter in its “AC Voltage” mode.
The analog-to-digital converter input circuit features adjustable digital, low-pass filtering, 12- to 18-bit resolution (depending on the filter setting) and has several different input ranges. These many ranges allow ±50,000 count resolution (at the slowest filter setting) across a wide variety of input ranges.
