POWER SUPPLY REQUIREMENTS
The G12 requires a 10-30 VDC power supply. Your unit may draw
considerably less than the maximum rated power depending upon the
features being used. As additional features are used your unit will draw
increasing amounts of power. Items that could cause increases in
current are modules, additional on-board communications, SD card, and
other features programmed through Crimson.
To ensure you do not exceed the capacity of your Graphite host power
supply, calculate the total power consumption required for all of your
planned modules. Each module’s maximum power consumption is listed
in the Specifications of their Product Bulletin. The total power available
for modules is listed in the specifications of the Graphite host.
In any case, it is very important that the power supply is mounted
correctly if the unit is to operate reliably. Please take care to observe the
following points:
– The power supply must be mounted close to the unit, with usually
not more than 6 feet (1.8 m) of cable between the supply and the
operator interface. Ideally, the shortest length possible should be
used.
– The wire used to connect the operator interface’s power supply
should be at least 22-gage wire suitably rated for the temperatures
of the environment to which it is being installed. If a longer cable run
is used, a heavier gage wire should be used. The routing of the
cable should be kept away from large contactors, inverters, and
other devices which may generate significant electrical noise.
– A power supply with an NEC Class 2 or Limited Power Source (LPS)
and SELV rating is to be used. This type of power supply provides
isolation to accessible circuits from hazardous voltage levels
generated by a mains power supply due to single faults. SELV is an
acronym for “safety extra-low voltage.” Safety extra-low voltage
circuits shall exhibit voltages safe to touch both under normal
operating conditions and after a single fault, such as a breakdown of
a layer of basic insulation or after the failure of a single component
has occurred. A suitable disconnect device shall be provided by the
end user.
I/O MODULE INSTALLATION
The physical order of all installed modules must match the modules
order in Crimson. Torque screws to 6.0 pound-force inch [96 ounce-force
inch] (0.68 N m).

WARNING: Disconnect all power

removing modules.
CONFIGURING A G12
The G12 is configured using Crimson
®
software. Crimson is available
as a no charge download from Red Lion’s website. Crimson updates for
new features and drivers are posted on the website as they become
available. By configuring the G12 using the latest Crimson version, you
are assured that your unit has the most up to date feature set. Crimson
software can configure the G12 through the RS232 PGM port, USB port,
or SD card.
The USB port is connected using a standard USB cable with a Type B
connector. The driver needed to use the USB port will be installed with
Crimson.
The RS232 PGM port uses a programming cable made by Red Lion to
connect to the DB9 COM port of your computer. If you choose to make
your own cable, use the “G12 Port Pin Out Diagram” for wiring
information.
The SD card can be used to program a G12 by placing a configuration
file and firmware on the SD card. The card is then inserted into the target
G12 and powered. Refer to the Crimson literature for more information on
the proper names and locations of the files.
USB, DATA TRANSFERS FROM THE SD CARD
In order to transfer data from the SD card via the USB port, a driver
must be installed on your computer. This driver is installed with Crimson
and is located in the folder C:\Program Files\Red Lion Controls\Crimson
3.0\Device\ after Crimson is installed. This may have already been
accomplished if your G12 was configured using the USB port.
Once the driver is installed, connect the G12 to your PC with a USB
cable, and follow “Mounting the SD” instructions in the Crimson 3 user
manual.
INSERTION/REMOVAL OF THE SD CARD
Insert the SD card into the slot provided with the card oriented as shown.
The card is inserted properly when the end of the card is flush with the
Graphite case. To remove the SD card, push in slightly on the card.
