GENERAL DESCRIPTION

The Model GMTC, GMRTD, GMINI, and GMINV are 16-bit analog input
modules designed for use with the Graphite Series. These modules provide a
means of high-density signal measurement for data-acquisition applications.
The GMTC module accepts a wide range of thermocouple types, while the
GMRTD accepts various RTD inputs. The GMINI and GMINV accept 0/4-20
mA and ±10 V process signals, respectively.

The modules connect and communicate via proprietary USB connection to the
various Graphite host devices. The Graphite host devices, equipped with serial
ports as well as an Ethernet port(s), allows the system to share data with PCs,
PLCs, and SCADA systems. The maximum number of modules varies for each
Graphite host device, see specific models for details.

Once programmed, the module will continue to operate/ control independent of
the Graphite host device as long as power is applied. Remove power from the host
device before installing or replacing any modules.

DIMENSIONS In inches (mm)

CONFIGURATION

The Graphite Series is configured with Windows® compatible Crimson®
software. The software is an easy to use, graphical interface which provides a
means of configuration and commissioning of new systems, as well as routine
module re-calibration.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.

Do not use the module to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the module. An independent and redundant
temperature limit indicator with alarm outputs is strongly recommended.

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded (screened) cables for all Signal and Control inputs. The shield

(screen) pigtail connection should be made as short as possible. The

connection point for the shield depends somewhat upon the application.

Listed below are the recommended methods of connecting the shield, in order

of their effectiveness.

a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

c. Connect the shield to common of the module and leave the other end of the

shield unconnected and insulated from earth ground.

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run through metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

is near a commercial radio transmitter. Also, Signal or Control cables within

an enclosure should be routed as far away as possible from contactors, control

relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

Therefore, keep cable runs as short as possible.

5. In extremely high EMI environments, the use of external EMI suppression

devices such as Ferrite Suppression Cores for signal and control cables is

effective. The following EMI suppression devices (or equivalent) are
recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)
TDK part number ZCAT3035-1330A
Steward part number 28B2029-0A0

Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3

Note: Reference manufacturer’s instructions when installing a line filter.

6. To protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid state
outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.

RLC part numbers: Snubber SNUB0000

Varistor ILS11500 or ILS23000

Note: Reference manufacturer’s instructions when installing any EMI

suppression device.

7. Also care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could effect the instrument’s operation.

Visit RLC’s web site at www.redlion.net for more information on EMI

guidelines, Safety and CE issues as they relate to Red Lion Controls products.

HARDWARE INSTALLATION

Modules must be installed beginning with slot 1 (left-most slot), with no
empty slots between the modules, and the order must match the modules order
in Crimson. Torque screws to 6.0 pound-force inch (96 ounce-force inch)

WARNING: Disconnect all power
to the unit before installing or
removing modules.

WIRING CONNECTIONS

All conductors should meet voltage and current ratings
for each terminal. Also, cabling should conform to
appropriate standards of good installation, local codes and
regulations and be suitably rated for the temperatures of
the environment to which it is being installed. When
wiring the module, use the numbers on the label to identify
the position number with the proper function. Strip the
wire, leaving approximately 1/4" (6 mm) of bare wire
exposed. Insert the wire into the terminal, and tighten.

LEDS

STS – STATUS LED

The Status LED is a green LED that provides information regarding the state
of the module. This includes indication of the various stages of the start-up
routine (power-up), as well as any errors that may occur.

Startup Routine

Off

Flashing Green Module switching to configuration.

Green Module performing normally.

Module is currently running the boot loader and/or
being flash upgraded by Crimson.

ALM – ALARM LED

The Alarm LED indicates the presence of an input fault condition. When one
or more Input Fault Alarm bits is high, the LED turns on. The alarms may be
disabled for unused inputs.

FIRMWARE UPGRADE

The module’s firmware is stored in flash memory so that software/hardware
conflicts are avoided, and so features can be added in the future.

During a download, Crimson compares its own library of firmware files with
those stored in the module. If they do not match, Crimson will download the
necessary firmware.

Error States

Flashing Green

Module is controlling properly, but has lost
communication with the Host.

CONFIGURATION

Programming is done via Crimson® software, a Windows® compatible
configuration interface. Please see the Crimson manual for more information.
