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.
1.3.1 Features
1.3.2 Chassis Models
1.3.3 Channel Types
Input Channels
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 Calibration
• Field selectable, digital, low-pass filtering (“damping”) on each Input channel

Output Channels
Virtual Channels
page 12 008-0608-00
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 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.
• 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
1.4.2 Benefits
1.4.3 Information Stored
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 memory 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.
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 requirements.
• A Factory Calibration Sheet Data area, unalterable by the customer, can be copied back into the User Calibration Data.
The following information is stored inside transducers equipped with Signature Cali-
bration:
• 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.

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.

2.2 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.
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 “
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 “
TYPE
Menu Item” on page 67 to select another calibration type.
CALIBRATION
When the instrument enters its normal operating mode (RUN mode), you will see the
following format on the front panel display:
1• 00000. 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 charac-
ters).
• Tare indicator: A “

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 Sen-
sotec.
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.
Getting Started Quickly2
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
3.2 INITIALIZE Mode
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.
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.

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.

The pinout for the 25-pin System connector is provided later in this chapter. The
pinouts for the individual channels are located in the chapter for that channel.
The panel cutout size conforms to the 3/8 DIN standard. Panel-Mounting Jacks
(order code AA928) are available that slide into two slots at the sides of the instrument. Use the following procedure to mount an SC1000 or SC2000 into a panel.
SC Series Instruction Manual page 27
Figure 4-2: Panel Cutout Drawing for SC1000 & SC2000 (not to scale)
Step 1: In the panel or rack, cut a hole as shown above. The panel may be up to 1/4”
in thickness.
Step 2: Use an 0.062" Allen wrench to remove two set screws that hold the Panel-
Mounting Jacks to the case. To do this, insert the wrench into the side slots at
the rear. Remove the screws completely.
Step 3: Remove the Panel-Mounting Jacks by sliding them toward the rear. If the jacks
don't slide easily, tap them gently.
Step 4: Put the instrument through the hole in the panel.
Step 5: Reinsert the Panel-Mounting Jacks into the slide slots. Slide them as far
toward the panel as possible.
Step 6: Reinsert the setscrews and tighten them. This will force the Panel-Mounting
Jacks toward the rear side of the panel, drawing the instrument tightly into
place.
