GENERAL DESCRIPTION
The 4.3-inch G3 Kadet 2 was designed for applications in which available
mounting space is at a premium. Though diminutive in size, the G304K2 boasts
a bright TFT display with 32K-color support. With a resolution of 480 x 272, the
Kadet 2’s 4.3-inch display has a higher resolution and better image clarity than
most 6-inch HMIs.
The G304K2 performs the functions of a multiple protocol converter, using
two high-speed RS-232/422/485 communications ports and a 10 Base-T/100
Base-TX Ethernet port. The Ethernet port supports up to four protocols
simultaneously, allowing dissimilar Ethernet based products to communicate
with one another.
The G3 Kadet 2 range of HMIs is programmed with Red Lion’s free Crimson
3 software. Crimson 3 offers easy to use drag and drop communications
configuration, while the embedded image library allows the programmer to
create intuitive screens and prompts for the operator.
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 controller 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 unit.
CAUTION: Risk Of Danger.
Read complete instructions prior to
installation and operation of the unit.
CAUTION: Risk of electric shock.
CONTENTS OF PACKAGE
- G304K2 Operator Interface.
- Hardware packet for mounting unit into panel.
- Terminal block for connecting power.

MOUNTING INSTRUCTIONS
The unit can be mounted into enclosures with a depth of 4". It is recommended
that the unit be mounted on the front panel of a steel enclosure. Allow clearance
of 1" around the sides of the unit for the mounting hardware. Allow 2.5" along
the bottom edge if using Red Lion communication cables.
Place the unit in the panel cutout. Slide clamps into the four holes provided
at the top and bottom of the case. Tighten the clamping screws in an even pattern
until the unit is secured in the panel. Caution: Do not over tighten the clamps.
To seal to NEMA4 specifications, all supplied mounting clamps must be used.
(Torque is 2.6 – 3.5 in/lb.) The panel must not flex more than 0.010".

POWER SUPPLY REQUIREMENTS
The G304K2 requires a 24 VDC ±20% power supply. Please take care to
observe the following points:
- The wire used to connect the operator interface’s power supply should
be at least 22-gage wire. 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 a Class 2 or SELV rating is to be used. A Class 2
or SELV 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.

CAUTION: The circuit board contains static sensitive
components. Before handling the operator interface without
the rear cover attached, discharge static charges from your
body by touching a grounded bare metal object. Ideally,
handle the operator interface at a static controlled clean
workstation. Also, do not touch the surface areas of the
circuit board. Dirt, oil, or other contaminants may adversely
affect circuit operation.
