Customer Information Sheet
Every instrument is shipped with a Customer Information Sheet
which documents important information specific to each instru-
ment, such as:
•
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.
Communications Guide
The "SC Series Communications Guide", document 008-0610-
00, describes in detail how to communicate with an SC Series
instrument using RS-232 and RS-485. Wiring diagrams, sample
programs, and descriptions of each command are included.
A printed copy of this document is available for order, or you may
download it from http://measurementsensors.honeywell.com.
Supplemental Instructions
If an instrument is configured with Mathematics Virtual channels,
one or more sets of Supplemental Instructions may be included.
These instructions contain important information about which in-
dicator lights, Function Input pins and/or Limit Output pins of the
System connector are used by the Mathematics Virtual channel.
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 chan-
nels, and Output channels are available to allow the configura-
tion 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
The main features of the models SC2000, SC2001 and SC3004
are:
•
Four alarm limits (optional sixteen), with versatile setup
•
Automatic setup, calibration, and scaling of strain-gage sen-
sors through the use of Signature Calibration
•
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 maxi-
mum) 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

1.3.2 Chassis Models
Several models (i.e. chassis types) are available:
•
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
1.3.3 Channel 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 transduc-
ers 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 ampli-
fier
•
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 chan-
nel number. They include:
•
Relay Output channels, which can add additional limits to the
standard four.
•
DAC Output channels, which provide additional voltage or
current outputs.
Virtual Channels
Virtual channels are software based devices that occupy a chan-
nel 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.
