Control Techniques 304K User manual

GENERAL DESCRIPTION
The 4.3-inch CTVUE-304K was designed for applications in which available
mounting space is at a premium. Though diminutive in size, the 304K boasts a
bright TFT display with full 256-color support. With a resolution of 480 x 272,
the 4.3-inch display has a higher resolution and better image clarity than most
6-inch HMIs.
The 304K offers two high-speed serial ports in the form of one RS-232 and
one RS-232/422/485 ports. This allows the operator interface to simultaneously
communicate with devices from different manufacturers, as well as to perform
protocol conversion.
The 304K is programmed with CTVue Configurator 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
- 304K 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.
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. The panel must not flex more than 0.010".

POWER SUPPLY REQUIREMENTS
The 304K requires a 12-28 VDC 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.

CTVue CONFIGURATOR SOFTWARE
CTVue Configurator Software is available as a free download from Control
Techniques’s website or it can be purchased on a CD, see “Ordering
Information” for part number. 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.
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 304K
If for any reason you have trouble operating, connecting, or simply have
questions concerning your new 304K, contact Control Techniques’s technical

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.
