Introduction
Overview of the Scanner 1140
The Scanner®1140 is an economical, single stream measurement Remote Terminal Unit (RTU) with flow and
pressure control capability. It offers a powerful alternative to chart recorders in gathering data for natural gas
production and includes a full range of operator selectable mass, energy and volume algorithms.
Cameron’s Barton DPE+ Multi-Variable Transducer (MVT) mounts directly to the Scanner 1140 to provide
accurate, low cost measurement for both static and differential pressures in a single device. The 1140 can also use
the MVX®or MVX®-II multi-variable transmitter to provide differential pressure, static pressure and temperature
inputs to the Scanner. The Scanner 1140 also accepts inputs from low-power (1-5 Vdc) and 4-20 mA
transmitters, RTDs, and pulse-producing devices such as the Barton and NuFlo turbine meters.
The Scanner 1140 is available in four different models (1140T, 1140C, 1140L and 1140G) to meet various
customer needs.
An intelligent 6Vdc, Class I, Div.1 Intrinsically Safe power management system ensures that the Scanner 1140T
consumes minimum power while collecting and processing data. It stores up to 60 days of flow history with an
audit trail of all events, alarms and user changes. The memory for this information is secured against power
failures with a separate replaceable lithium back-up battery.
A 12Vdc system is available for Class I, Div. 2 non-sparking applications (Scanner 1140C and 1140L).
Stored data can be downloaded on-site, or communicated to a central location. Standard communications and
status/pulse inputs can easily be expanded.
The following features in the Scanner 1140 provide convenient and flexible operation:
Programmable Memory - A full set of menu-selectable calculation options are stored in the FLASH memory in
each Scanner 1140. As new industry standards are adopted, new programs are easily loaded from a PC
without EPROM chip changes. (See the ScanLoad, WinsLoad or ScanFLASH utility software.)
Security - Five security levels and selectable display options ensure convenient use while maintaining full
protection of configuration and flow history.
Power Supplies - Choose from line power or various battery configurations with thermoelectric or solar charging
options to minimize installation costs and meet site and intrinsic safety requirements.
Sampling Frequency - Select ideal end device sampling rates to optimize the Scanner 1140’s ability to
simultaneously measure and control while conserving power.
Calibration - A variety of methods are available for linearizing different end devices to maintain the highest
accuracy. A detailed record of calibration information is stored automatically in the Scanner User Change
Log and can be used to monitor and diagnose transmitter performance.
Controls - Various control options are easily configured using simple menus with input/output selections for both
throttling and ON/OFF control. Four status input/outputs and an analog output make the Scanner 1140 ideal
for:
•proportional integral control
•emergency shutdown
•run switching
•programmable logic status

Scanners 1140T, 1140C, 1140L, and 1140G
The Scanner 1140T, often referred to as the standard Scanner 1140 unit, is a 6Vdc EFM rated for Class I,
Div.1 Intrinsically Safe applications. The device has no integral communications. It is housed in a fiberglass-
reinforced plastic enclosure. All Class I, Division 1 installations require an intrinsically safe barrier adapter
(Part No. 9A-30058901) between the Scanner and the DPE+ transducer. The adapter is not required for Class
I, Division 2 installations.
The Scanner 1140C has the same main board as the Scanner 1140T model but with the following features:
•Class I, Div. 2 non-sparking certification
•a larger enclosure that can accommodate a communication device
•12 Vdc battery/charger control (up to 55 amp-hours)
•a power supply for powering a communication device
•an optional lightning arrestor
The Scanner 1140L has many of the features of the 1140C. However, it has a metal enclosure and its main
board is mounted on an aluminum plate instead of in an aluminum extrusion. It is limited to a 32-amp-hour
battery. The 1140L can be used with standard I/O with depluggable terminals or limited I/O with soldered
terminals.
The Scanner 1140G (shown below) is comprised of a standard Scanner 1140T main board, but has no integral
enclosure with a battery. It is designed to be installed in another enclosure or panel mounted. It is intended to
be a value-added product for integrators and E & C firms.
Scanner Software
A variety of software programs are available for configuring, monitoring, downloading, retrieving data,
reading and creating reports from collected data:
•ScanWin™- ScanWin is a Windows™based software program that is used to monitor, configure and
download Scanner Measurement RTU data on-site. Such data is displayed graphically and in tables.
Reports are printable from ScanWin. Monitor and download all firmware versions and configure version
4.x firmware.
•ScanPC®- ScanPC is a DOS / Windows™98 based software program for a PC that is used to monitor,
configure, and download Scanner Measurement RTU data on-site. Scanner files can be printed in a
universal report format or, outputted in either comma separated, or tab separated text formats. All report
files are readily imported into spreadsheet and database software programs. Used with version 2.x and
3.x firmware.
