Chapter 11, “AC/AC-LVDT Input Channel”, explains how to wire, configure, operate and calibrate AC/AC-LVDT Input Channels with your transducers. Chapter 12, “High-Level Input Channel”, explains how to wire, configure, operate and calibrate High-Level Input Channels with your amplified transducers, in-line amplifiers, or DC-DC LVDTs.
1 1.2 Related Documents Every instrument is shipped with a Customer Information Sheet which documents important information specific to each instrument, such as: • • • • Communications Guide part number, date of manufacture, list of all installed channels and their setup information, customer specific SensoCode programming of Mathematics Virtual channels and operation notes.
1.3 What is the SC Series? The SC Series of Signal Conditioners/Indicators are versatile, multi-channel devices designed to operate with many different types of sensors. Several different chassis types, Input channels, and Output channels are available to allow the configuration of an SC instrument to meet a variety of measurement and control needs. The operation of an SC instrument is based on digital technology to provide improved accuracy, superior ease of setup, and a wealth of features. 1.3.
SC Series Instruction Manual page 13 Introduction Mathematics Virtual channels run small programs written in an interpretive language called SensoCode. This provides great flexibility which allows the SC Series to do many jobs which otherwise requires a personal computer or PLC.
1.4 What is Signature Calibration? 1.4.1 Overview A small integrated circuit is located either inside the transducer, in an in-line package between the instrument and the transducer, or in the connector of a cable. All data necessary to set up the transducer with the instrument are stored (even linearity data), and setup is automatic when a new transducer is connected to the instrument. The Strain-Gage Input channel of the SC Series is designed to operate with Signature Calibration.
The following items are required to set up an SC Series instrument with your transducer: • • • • • • SC Series instrument Transducers that are to be connected to the instrument For each transducer to be connected to the instrument, a connecting cable. This cable will have a 12-pin, green, plastic connector on one end and the transducer’s mating connector on the other end. Usually, this cable is ordered along with the instrument and transducer.
2.3 Turn on the Instrument Connect the power cord between the instrument power source and the instrument, and turn the On/Off switch on the back of the instrument to the On position. The instrument enters its INITIALIZE mode that lasts a few seconds per channel. As each channel in the instrument is initialized, the transducer's serial number may be seen on the display if the transducer has a Signature Calibration Module in it. NOTICE If the channel’s display flashes “APPLY 00000.
2 2.4 Use the SETUP Menus to Enter Transducer Information • • You are using a transducer equipped with Signature Calibration, or The transducer and instrument were purchased together and set up by Sensotec. Otherwise, you must enter information about your transducer into the SETUP menu of the channel to which it is connected. See the appropriate chapter of this manual for that card type. 2.

The SC Series instruments have four modes of operation: • • • INITIALIZE, to test the instrument upon power up RUN, normal operation ERROR, which indicates that an abnormal situation has occurred that stopped the operation of the instrument • SETUP, a menu which allows setup and calibration of the chassis and its channels Each of these will be described in this chapter. 3.2 INITIALIZE Mode When the instrument is powered up or otherwise reset, it enters the INITIALIZE mode.
3.3 RUN Mode After the INITIALIZE mode finishes, the instrument enters the RUN mode, its normal mode of operation. 3.3.1 Display Model SC3004 and upper line of SC1000, SC2000, SC2001 The display will show a channel number on the far left, followed by the channel’s operation messages. For example, a Strain Gage amplifier channel will use the format below: 1• 00000. PSIG " where: • • • • • Lower Line of SC1000, SC2000, SC2001 Channel number: “1” is the channel number.
3.3.4 [CHANNEL] button If the configuration of the instrument contains more than one channel, the left most characters of the display indicates which channel the display is monitoring. Pressing and releasing the [CHANNEL] button will cause the next channel to be displayed. On instruments with a dual-line display, the [CHANNEL] button cannot be used to change which channel the lower line is monitoring. That is selected with the “DISPLAY MENU -> LOWER CHANNEL” menu item.
3.4 ERROR mode The instrument enters the ERROR mode when a critical error occurs that prevents the instrument from operating. The display alternates between displaying a two-digit code in the form “ERROR xx ON CH.yy” and a short description of the error. The first two digits “xx” hold the error code. The last two digits, “yy” is channel number that caused the error. For example, “ERROR 60 ON CH.01” indicates that error number 60 occurred on channel 1.
3 3.5 SETUP Menu mode 3.5.1 Available Menus Each major function of the instrument has its own SETUP Menu. See “Setup Menu Reference” on page 157. 3.5.2 Entering and Exiting the SETUP Menu mode To enter the SETUP Menu mode, press and hold the [UP] and [DOWN] buttons at the same time until you see “SETUP” on the display. When you release the buttons, you will see the first SETUP Menu item. 3.5.

Limits are signal levels at which some action (such as a light to come on or go out, or a switch to close) is desired to take place. The point at which this action takes place is the SET POINT. The RETURN POINT is the point at which the action that took place at the SET POINT returns to its original state. If the SET POINT and RETURN POINT are identical and the signal level is changing slowly near these points, “chatter” may result and the limit rapidly energizes and de-energizes.
9.2 Limit Operation 9.2.1 Actions When Activated When Limits 1, 2, 3, or 4 are activated, the following actions occur: • • • The front panel light for the limit will illuminate. The corresponding open-collector Limit Output pin on the System connector will be connected to the DGND (Digital Ground) pin. If a Relay Output channel is installed, the relay for the limit will activate. A Relay Output channel can be installed for Limits 5, 6, 7, and 8.
9 9.3 Limit Menus There are four, eight, twelve or sixteen Limit menus depending on how many Relay Output channels are installed in the instrument. These menus determine the operation of the each of the limits. If no Relay Output channels are installed, there are four Limit menus which control the operation of the open-collector Limit Outputs on the System connector. Detailed instructions on operating the instrument in the SETUP Menu mode can be found in “SETUP Menu mode” on page 23.

The Strain-Gage Input channel provides a DC excitation voltage to and accepts millivolt signals from strain-gage transducers. These millivolt signals are digitized, converted into engineering units, and placed into the track, peak and valley data values of the channel. Setup and calibration of the channel can be made manually through the SETUP mode or automatically if the transducers are equipped with Signature Calibration. See “What is Signature Calibration?” on page 14.
10.2 Wiring Connect the transducer to a Strain-Gage Input channel by wiring it to the 12-pin connector of that channel. The Customer Information 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.
10 10.3 Calibration Procedure Step 1: Wire the transducer to the channel’s connector. See “Wiring” on page 60 for details. Step 2: Enter the CALIBRATION TYPE. There are three methods that can be used to calibrate the transducer to the Input Channel. Each has advantages and disadvantages as described in “CALIBRATION TYPE Menu Item” on page 67. It is important to know your application in order to select the appropriate calibration type. Step 3: Enter the CALIBRATION DATA.

10 10.5 Channel Menu 10.5.1 OPERATION Sub-Menu This menu controls the operation of this channel when the instrument is in the RUN mode. Menu Item This enables or disables the channel’s automatic zeroing function. The auto-zero function can be beneficial by removing the effect of slight temperature shifts in the transducer’s output. The two options for this menu item are “ON” and “OFF”.
POWER-ON SOURCE Menu Item This menu selects which value is displayed by the channel when first entering the RUN mode. The choices are: • • • • • • page 64 008-0608-00 “TRACK” means the live tracking value of the channel. “PEAK” means the highest value of the channel. “VALLEY” means the lowest value of the channel. “TRACK / PEAK” means the live tracking value and the highest value of the channel. (Only available on Model SC3004).
Menu Item Selects the number of digits displayed by the channel. The choices are: • “5 DIGIT-BIPOLAR” displays both positive and negative numbers with five full digits (±99999). • “6 DIGIT-UNIPLOAR” displays positive numbers with six full digits (999999) and negative numbers with five full digits (-99999). • “7 DIGIT UNIPOLAR” displays positive number with seven full digits (9999999) and negative numbers with six digits (-999999).
10.5.3 AUXn FUNCTION Menu Items The AUX1 FUNCTION and AUX2 FUNCTION menu items determine what happens when the Auxiliary Function pins (labeled as “AUX1” and “AUX2”) on the channel’s connector are activated. These pins are “activated” when they are connected to the (-)Signature (labeled as “-MEM”) pin. The choices are: • “DISABLED” means that activating the pin does nothing. • “TRACK HOLD” means that the tracking, peak and valley values will not be updated.
10 This chooses the type of calibration technique to be used. There are three methods that can be used to calibrate the transducer to the Input Channel. Each has advantages and disadvantages as described in the table below. Table 4-4: Comparison of Calibration Types Shunt Calibration mV/V Calibration 2-, 3-, or 5point Known Load Calibration ...for most applications no yes no ...when frequently swapping transducers yes yes no ...
a known, precision resistor into the transducer circuit, which causes a predictable apparent signal. The instrument then takes a reading and adjusts itself using the “SHUNT CAL VALUE” register. • “TYPE= MV/V CAL” means Millivolt-per-Volt Calibration. First, you are prompted to apply the load entered in the “ZERO SCALE VALUE” register. Next, the instrument takes a reading from an accurate, internal mV/V reference.
10 EXCITATION Menu Item This enters the values that will be used by the instrument when it calibrates itself to the transducer. The menu items that are displayed will change according to what the CALIBRATION TYPE is set for. This sets the excitation voltage used to power up the transducer. The choice are: • “EXCITATION=5VDC” means 5 volts DC excitation. • “EXCITATION=10VDC” means 10 volts DC excitation. This menu item may be automatically updated by a transducer’s Signature Module.
Figure 10-2: Shunt Calibration Resistor Location To verify proper transducer operation, you can apply the shunt resistor to the transducer while the instrument is in the RUN mode. Press and hold the [ENTER] button for three seconds; this will apply the shunt resistor and display the reading. 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.
10 This menu item performs a calibration according to what was entered in the CALIand CALIBRATION DATA menu items. BRATION TYPE NOTICE Before performing a calibration, the transducer must be connected to the instrument, the CALIBRATION TYPE must be selected (see “CALIBRATION TYPE Menu Item” on page 67), and the CALIBRATION DATA must be entered (see “CALIBRATION DATA Sub-Menu” on page 69).

UNITS). When you have applied this load to the transducer, press [ENTER].
10 DAC. CHANNEL Menu Item This sub-menu contains four items that control the Digital-to-Analog Converter (DAC) output of the channel. This chooses which channel will drive the DAC output. Normally, the DAC located on a particular channel will be driven by that channel, but that need not be the case. For example, if several channels were assigned to load cells on a weighing platform, the sum of all channels could (mathematically) drive one channel’s DAC output.
10.5.8 SIGNATURE MODULE Sub-Menu UPDATE SIG.MOD? Menu Item Updates the information stored in the transducer’s Signature Module with any new settings that is entered into the instrument with the SETUP menus. The settings that will be updated are: • EXCITATION • FULL SCALE MV/V • FULL SCALE VALUE • SHUNT CAL VALUE • DISPLAY. UNITS Note that changes made to the instruments display setup (such as decimal point and count-by settings) are not updated into the Signature Module.
10 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. This is useful when calibrating or trimming the readout connected to the Analog Output.
10.6 Analog Output Configuration 10.6.1 Identifying the Output Type A Strain-Gage Input channel is available with one of two types of digital-to-analog (DAC) outputs: voltage or current. You can determine which type of output a channel has by one of three ways: • • • 10.6.2 Channel Menu Items Consulting the instrument’s Customer Information Sheet Examining the SYSTEM MENU -> CONFIGURATION -> CHANNEL nn TYPE menu item where nn is the number of the channel.
