GENERAL DESCRIPTION
The 4.3-inch CTVUE-304KE was designed for applications in which
available mounting space is at a premium. Though diminutive in size, the
304KE boasts a bright TFT display with 32K-color support. With a resolution of
480 x 272, the 304KE’s 4.3-inch display has a higher resolution and better image
clarity than most 6-inch HMIs.
The 304KE 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 304KE HMI is programmed with CTVue Configurator 3 Software. The
software 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.
CONTENTS OF PACKAGE
- 304KE Operator Interface.
- Hardware packet for mounting unit into panel.
- Terminal block for connecting power.
- Spare fuse.

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 Control Techniques’ 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 304KE 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.
PC CONNECTION
Configuration files are downloaded to the 304KE via the PC port, which can
be connected to a computer via various cables.

CTVue CONFIGURATOR 3 SOFTWARE
CTVue Configurator 3 Software is available as a free download from Control
Techniques’ website. The latest version of the software is always available from
the website, and updating your copy is free.
FRONT PANEL LEDS
There are three front panel LEDs. Shown below is the default status of
the LEDs.
LED INDICATION
BLUE (COM)
FLASHING Communications are active.
GREEN (CPU)
STEADY CPU is functioning
ORANGE (PWR)
STEADY Power is applied.
TOUCHSCREEN
This operator interface utilizes a resistive analog touchscreen for user input.
The unit will only produce an audible tone (beep) when a touch on an active
touchscreen cell is sensed. The touchscreen is fully functional as soon as the
operator interface is initialized, and can be operated with gloved hands.
TROUBLESHOOTING YOUR 304KE
If for any reason you have trouble operating, connecting, or simply have
questions concerning your new 304KE, contact Control Techniques’ technical
support. For contact information, refer to the front page of this bulletin for
phone and fax numbers.

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.
