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.
2.1 Locate Required Parts and Information The following items are required to set up an SC Series instrument with your transducer: • • • • • • 2.2 Connect the Transducer to the Correct Channel of the Instrument For each transducer, attach its connecting cable to the transducer, and then to the correct 12-pin channel-connector on the instrument.
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.
2.4 Use the SETUP Menus to Enter Transducer Information You can skip this step if: • • 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.
3.1 Operating Modes The SC Series instruments have four modes of operation: • • • • 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.
3.3.2 [VALUE] button NOTICE The [VALUE] button is not used by SC1000 instruments in the RUN mode. After the channel number, the next characters indicate which data value for the dis- played channel is shown. There are three (possibly four) data values available from each channel: •...
Limit 1 and Limit 2 are deactivated and Limit 3 and Limit 4 are acti- vated. Since the SC1000 is not equipped with limits, the lower line of the display will be blank. See “LOWER MODE Menu Item” on page 51.

Chapter 9 Limits 9.1 Understanding Limits, Set Points and Return Points 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.
9.2 Limit Operation 9.2.1 Actions When When Limits 1, 2, 3, or 4 are activated, the following actions occur: Activated • 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.
9.3 Limit Menus 9.3.1 Overview 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.

16.1 Features The Mathematics Virtual Channel is a powerful, flexible means to allow SC Series Instruments to perform simple to moderate functions that previously required the use of expensive programmable logic controllers (PLC). A Mathematics Virtual Channel is akin to a PLC; it can execute programs written in an interpretive language called SensoCode.
16.2 Wiring A Virtual Channel exists in software only; it does not occupy a physical slot inside of the instrument’s chassis. However, a Virtual Channel does require a channel number. A SensoCode program that is executed by a Mathematics Virtual Channel can use the System connector’s Limit Output pins and Function Input pins for its own purposes.
16.3 Setup Procedure If you are not familiar with operating the instrument in the SETUP menu mode, see “SETUP Menu mode” on page 23. A listing of all menu item is given in “Setup Menu Reference” on page 157. Step 1: Examine the Supplemental Instructions. Step 2: Wire to the pins on the System connector.
16.4 Channel Menu Each Mathematics Virtual Channel can have its configuration and SensoCode pro- gramming examined via its channel menu. It is not possible to alter the SensoCode program with the SETUP menu. Detailed instructions on operating the instrument in the SETUP Menu mode can be found in “SETUP Menu mode”...
