1.3 What is the SC Series?

1.3.1 Features

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.

The main features of the models SC1000, SC2000, SC2001 and SC3004 are:

Four alarm limits (optional sixteen), with versatile setup (not available on Model SC1000)

Automatic setup, calibration, and scaling of strain-gage sensors through the use of Signature CalibrationTM

Field selectable, digital, low-pass filtering (“damping”) on each Input channel

Up to ±50,000 part resolution

Field selectable five-, six - or seven-digit (9,999,999 maximum) display

RS-232 communications standard (RS-485 optional)

Local or remote setup using the RS-232 or RS-485 port

Push-button on/off tare feature

1.3.2Chassis Models Several models (i.e. chassis types) are available:

SC1000: 1 to 4 physical channels, 3/8 DIN case, no limits or peak detector

SC2000: 1 to 4 physical channels, 3/8 DIN case

SC2001: 1 to 4 physical channels, portable case

SC3004: 1 to 14 physical channels, 19” rack mount case, 1 to 3 quad-line displays

1.3.3Channel Types Channels can be one of three types: Input, Output, or Virtual

Input Channels

Input channels are hardware circuit boards with a unique channel number. Currently,

 

they are available for the following types of sensors:

 

• Strain-gage sensors, such as unamplified pressure transducers and load cells

 

• Sensors with voltage outputs, such as transducers with the Option 2a, 2b, 2c, 2d,

 

2g, 2j, 2k, 2p, 2t or 2y internal amplifier

 

• Sensors with current outputs, such as transducers with the Option 2j, 2k or 2n

 

internal amplifier

 

• AC-AC LVDTs (Linear Variable Displacement Transducers)

 

• DC-DC LVDTs

Output Channels

Output channels are hardware circuit boards with a unique channel number. They

 

include:

 

• Relay Output channels, which can add additional limits to the standard four (N/A

 

on Model SC1000).

 

• DAC Output channels, which provide additional voltage or current outputs.

Virtual Channels

Virtual channels are software based devices that occupy a channel number, but not a

 

physical slot, in an instrument.

 

• Split Display Virtual channels allow the displaying of any two channel’s track, peak

 

or valley values at the same time.

page 12 008-0608-00

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. It will automatically set itself up with transducers which contain the mem-

 

ory device, but can also be set up using a front-panel interactive procedure. The Sig-

 

nature Calibration module can also be programmed from the instrument’s front panel.

 

Signature Calibration is only available with unamplified strain-gage transducers.

1.4.2 Benefits

The benefits are:

 

• The transducer’s Calibration Record is always located where it is needed most...

 

with the transducer.

 

• The instrument is always set up correctly with the transducer.

 

• Interchanging of transducers and instruments is a quick process.

 

• A User Calibration Data area that can be altered by customers to fit their require-

 

ments.

 

• A Factory Calibration Sheet Data area, unalterable by the customer, can be cop-

 

ied back into the User Calibration Data.

1.4.3 Information

Stored

The following information is stored inside transducers equipped with Signature Calibration:

Full-scale mV/V: The full-scale millivolt-per-volt (mV/V) rating of the transducer when its full load is applied; also called “calibration factor”.

Shunt-Cal mV/V: The millivolt-per-volt output of the transducer when the shunt calibration resistor is placed across its (-)SIGNAL and (-)EXCITATION leads.

Shunt Resistance: The resistance value, in Ohms, that was used to obtain the shunt-cal mV/V value above.

Full-Scale Value: The full scale value of the transducer, in engineering units.

Engineering Units: The engineering units that the transducer is calibrated in (i.e. pounds, grams, pascals, inches of water, etc.).

Serial Number: The serial number of the transducer.

Excitation Voltage: The magnitude and type of signal used to excite the transducer.

Linearization Points (optional): These can be used by an instrument using Shunt Calibration or Millivolt-per-Volt Calibration to correct any non-linearity in the transducer and thus improve the accuracy of the system. An additional “multiple-point calibration” can be purchased with the transducer that allows linearity correction information to be placed into its Signature Calibration module.

Getting Started Quickly

2.1 Locate Required Parts and Information

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.

If the connecting cable was not ordered with the instrument, you may need to make this cable.

The transducer’s Calibration Record or Certificate of Calibration.

The Customer Information Sheet that shipped with your instrument. This sheet describes which cards are installed in each channel.

Power cord for the instrument.

2.2Connect 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.

The Customer Information Sheet indicates which serial numbered transducer is to be connected to each channel of the instrument.

If the instrument and transducer(s) were not purchased with a connecting cable, you may need to make this cable. For the transducer’s pin connections, see that transducer’s calibration record. For the pin connections for that channel of the instrument, see the appropriate chapter in this manual. For example, if you wish to wire to a Strain-Gage Input Channel see the chapter “Strain-Gage Input Channel” on page 59.

SC Series Instruction Manual page 15

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.” (or some other load value), the instrument has detected a transducer other than the one which was last calibrated with that channel. The instrument is prompting you to apply the requested load to the transducer so that a “mV/V Calibration” or a “Shunt Calibration” can take place.

After making certain that the correct transducer is connected this channel, press the [ENTER] button after you have applied the requested load to perform the calibration.

NOTICE

If the instrument displays error code 57 or 68, it has detected a transducer other than the one which was last calibrated with that channel. Furthermore, the channel cannot perform an automatic calibration because its calibration type has been set to “Known Load Calibration”.

Either re-connect the correct transducer to the channel, or see “CALIBRATION TYPE Menu Item” on page 67 to select another calibration type.

When the instrument enters its normal operating mode (RUN mode), you will see the following format on the front panel display:

100000. PSIG "

where:

Channel number: “1” is the channel number.

Value type: The next character indicates the nature of the following value.

A blank character indicates the tracking value. The instrument is “tracking” the signal, continuously updating the display in response to the signal from the transducer.

A “" character indicates the peak value (highest value seen since the [CLEAR] button was last pressed).

A “" character indicates the valley value (lowest value seen since the [CLEAR] button was last pressed).

Data value: “00000.” displays the value from the transducer in engineering units.

Units label: “PSIG” indicates the engineering units being used (up to 4 characters).

Tare indicator: A “"“ symbol indicates tare is off; a “Ë“ symbol indicates tare is on.

page 16 008-0608-00

2.4 Use the SETUP Menus to Enter Transducer Information

You can skip this step if:

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.

2.5 Calibrate the Transducers to Their Channels

You can skip this step if:

You are using a transducer equipped with Signature Calibration, or

The transducer and instrument were purchased together and set up by Sen-

sotec.

Otherwise, you must choose a calibration method (e.g. Shunt Calibration, mV/V Calibration, or Known Load Calibration) appropriate for your application and use the SETUP menu for that channel to calibrate the channel to the transducer. See the appropriate chapter of this manual for that card type.

2.6 The SC Series Instrument is Ready for Use

See “RUN Mode” on page 20 for information on how to operate the instrument while it is in the RUN mode.

Apply some test stimulus on the transducer to observe changes in the display.

SC Series Instruction Manual page 17

page 18 008-0608-00

3.1 Operating Modes

Chapter 3

Operating Modes

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.

Modes Operating 3

3.2 INITIALIZE Mode

When the instrument is powered up or otherwise reset, it enters the INITIALIZE mode. As the instrument enters this mode, all segments of the display and all front panel indicator lights (if available) illuminate momentarily. Next, each channel in the instrument is checked for proper operation.

If a problem is detected, the instrument may enter the ERROR mode.

Depending on the type of channel, other actions may occur. For example, a Strain-Gage channel will calibrate its analog-to-digital converter and attempt to read the transducer’s Signature Calibration information. If the transducer is equipped with Signature Calibration, the transducer’s serial number is displayed momentarily.

3.3.2 [VALUE] button

3.3.3 [CLEAR] Button

After the INITIALIZE mode finishes, the instrument enters the RUN mode, its normal mode of operation.

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:

100000. PSIG "

where:

Channel number: “1” is the channel number.

Value type: The next character indicates the nature of the following value.

A blank character indicates the display is being continuously updated by “tracking” the input signal to the channel.

A “" character indicates the peak value (highest value seen since the [CLEAR] button was last pressed).

A “" character indicates the valley value (lowest value seen since the [CLEAR] button was last pressed).

Data value: “00000.” displays the value from the transducer in engineering units.

Units label: “PSIG” indicates the engineering units being used (up to 4 characters).

Tare indicator: A “"“ symbol indicates tare is off; a “Ë“ symbol indicates tare is on.

The contents of the display’s lower line is selected with the “DISPLAY MENU -> LOWER MODE” menu item as either displaying a channel or indicating the status of Limits. See “Indicator Lights” on page 21.

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 displayed channel is shown. There are three (possibly four) data values available from each channel:

(blank), tracking data value

", peak data value, (highest value since the peak/valley detector was cleared)

", valley data value, (lowest value since the peak/valley detector was cleared)

Û", percentage of the Analog-to-Digital converter’s full-scale digitizing capability.

This data value is only available when the channel’s “DIAGNOSTICS->DISPLAY ADC” menu item is set to “ON”.

Pressing and releasing the [VALUE] button cycles though the available sources for data values for the displayed channel.

Pressing and releasing the [CLEAR] button will reset the peak and valley values of the channel being monitored by the display to the track value. Additionally, any limits in the instrument that are “latched” will be reset.

NOTICE

The [CLEAR] button is not used by SC1000 instruments in RUN mode.

page 20 008-0608-00

 

 

 

To clear the peak and valley values of all channels simultaneously, use the Sys-

 

tem connector’s Function Input #2 pin. See “System Connector” on page 35 for

 

details.

 

To clear the peak and valley values of a single channel regardless of which chan-

 

nel is being monitored by the display, use the channel’s AUX1 or AUX2 control

 

pins on its connector. See the particular chapter regarding that channel for

 

details.

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 “DIS-

 

PLAY MENU -> LOWER CHANNEL” menu item.

Shunt Calibration Check

If the [CHANNEL] button is held down for more than 3 seconds, the present chan-

 

nel’s shunt calibration value (if the channel has shunt calibration available) will be

To reset the channel’s display to zero, press the [TARE] button while in RUN

 

mode. To restore the tare value, press the [TARE] button again. The “Tare” indica-

 

tor will illuminate when tare is on.

 

To tare all channels simultaneously, use the System connector’s Function 1 Input

 

pin. See “System Connector” on page 35.

 

To tare a single channel regardless of which channel is being monitored by the

 

display, use the channel’s AUX1 or AUX2 control pins on its connector. See the

 

particular chapter regarding that channel for details.

3.3.6 Indicator Lights

 

Models SC1000, SC2000, SC2001

A “"“ symbol on the right side of a channel’s display indicates tare is off for that

 

channel; a “Ë“ symbol indicates tare is on.

 

If the lower line of the display is configured with the “DISPLAY MENU -> LOWER MODE

 

menu item as “LIMIT 01-04”, then the lower line will monitor the status of Limits 1, 2,

 

3 and 4. A “"“ symbol indicates a limit is deactivated; a “Ë“ symbol indicates a limit

 

is activated. For example:

 

L1" L2" L3Ë L4Ë

 

indicates that 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.

 

These indicators may be overridden by the operation of a Mathematics channel in

 

special applications.

Model SC3004

Front panel lights “L-1”, “L-2”, “L-3”, and “L-4”, monitor the status of Limits 1, 2, 3,

 

and 4. Model SC3004 instruments also include front panel lights labeled “L-5”, “L-

 

6”, “L-7” and “L-8” which monitor the status of optional Limits 5, 6, 7, and 8.

 

The function of the front panel lights may be overridden by the operation of a

 

Mathematics channel in special applications.

Modes Operating 3

SC Series Instruction Manual page 21

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.

While the instrument is in the ERROR mode, no other operations are taking place except for limited serial communications capabilities. See “Error Message List” on page 152 for a list of error codes and their probable causes.

4.1 Introduction

Chapter 4

Chassis Models

The SC Series of Signal Conditioners/Indicators are available in several different chassis models. In general, each chassis model operates in an identical fashion and can be ordered with any type of Input channels, Output channels, or Virtual channels.

Input channels and Output channels are printed circuit boards that occupy a physical slot inside the instrument’s chassis. 12-pin connectors are located on the rear panel to connect to each Input or Output Channel. Each channel in the instrument is identified by a number (channel 01, channel 02, etc.).

A Virtual channel exists in software only; it does not occupy a physical slot inside the instrument’s chassis. There is no rear-panel connector for a Virtual channel. However, a Virtual channel does require a channel number.
