Quickstarting the Device
This section outlines the steps needed to setup the EZTouchPLC and get it
started. This is not intended to explain specific details needed to start your
system. Rather, it provides aquick guide to give abroad picture of what is
needed to power-up EZTouchPLC system.
It is always recommended to make sure you have all the right parts to build
your system. This is what you will need to get started:
-EZTouchPLC unit
- USB Programming cable*
- 2.5mm blade screwdriver for I/O wiring (P/N EZIO-SCDRV)*
- Programming Software: EZSeries Editor Programming Software*
- 24VDC Power Supply*
* These accessories have to be purchased separately
Step 1: (Optional) Wire Input / Outputs
You may wire required inputs and outputs now or later. Using the 2.5mm
blade screwdriver, simply insert the wire and screw to tighten. Please refer to
the wiring section for information on connecting the Input/Outputs to the
EZTouchPLC terminals.
Step 2: Connect Power
Connect the power input wires to the EZTouchPLC power terminals as
outlined in the Powering the EZTouchPLC section. Supply 24VDC nominal
(20-28VDC) power to the system. Ensure the indicator LED located on the
PLC base is ON (green LED). If not, remove power from the system and
check all the wiring.
Step 3: Create a Project
Open your Touch Panel Editor and create your HMI screen and Ladder Logic.
The EZTouch Editor Software Manual explains the programming instructions
in detail. A sample project is outlined in the Programing Section.
Step 4: Transfer Project to Unit
The project can be transfered to the unit either serially or through the
Ethernet port. If connecting through the USB programming cable, ensure the
cable is connect to the unit and PC running the Editing Software. Then using
the Software, select File > Transfer to Panel. Under the dialog window select
the appropriate COM port that the USB is connected with and then click
Start.

Safety Considerations
Please follow all applicable local and national codes to ensure maximum safety
of the equipment and personnel. The installation and operational environment
must be maintained per the latest revision of these codes.
You are responsible to determine the codes to be followed and to verify the
compliance of equipment, installation, and operation with the latest revision of
these codes.
It is an absolute must to follow all applicable sections of:
-The National Fire Code
-The National Electrical Code (NEC)
-The National Electrical Manufacturer's Association (NEMA) codes
Safety Guidelines
Safety is the most important element of a proper system installation. Adhering
to these safety considerations ensures the safety of yourself and others, as well
as the condition of your equipment. We recommend reviewing the following
safety guidelines:
1) Disconnecting Main Power
The main power switch should be easily accessible to the operators and
maintenance personnel. It is important to make sure that all other
sources of power including pneumatic and hydraulic are de-energized
before starting the work on a machine or process controlled by the HMI.
2) Safety Circuits
Most of the machines are installed with safety circuits such as limit
switches, emergency stop push buttons, and interlocks. These circuits
should always be hardwired directly to the EZTouchPLC unit. These
devices must be wired in series so that when any one device opens, the
unit is automatically de-energized. This removes power to the machine.
These circuits should not be altered in any case, since this could result in
serious injury or damage to the machine.
3) Fail-Safe Operation
Our products are not fault-tolerant. They are not designed or intended
for use as online control equipment in hazardous environments requiring
fail-safe performance, such as in operation of nuclear facilities, aircraft
navigation or communication systems, air traffic control, direct life-
support machines, weapons systems, clutch control systems on presses, in
which the failure of the product could lead directly to death, personal
injury or severe physical or environmental damage. External fail-safe and/or
redundant components are required to make your control system fail-safe.
EZTouchPLC

Installation Considerations
Our products have been designed and tested for operation in the most
demanding industrial environments. Modern solid-state industrial controls are
complex electronic equipment that operate at low levels of voltage and current,
co-existing with components that operate at much higher levels of power. The
difference in operating power characteristics between the high and low power
control devices creates the possibility of unwanted signals being generated, thus
causing interference. The interference, which is a by-product of electrical noise,
is not present at all times. However, if it appears at random and for brief periods
of time, it can cause disruptions and errors in the operation of a control system.
Enhancement of a system's noise level immunity and its tolerance to other
environmental hazards can be accomplished by following proper system
installation guidelines. The recommendations are of a general nature and
constitute good industrial installation practice.
General Environmental Considerations
Avoid installing the EZTouchPLC unit in areas where the following
conditions may exist:
oEnvironmental temperatures above or below those specified for the
EZTouchPLC unit
oProlonged exposure to humidity and liquids which may be sprayed or
splashed on the equipment
oDusty environments where airborne particles may accumulate on
equipment causing reduction of heat dissipation and reduction in
effective electrical spacing between components
oAreas with excessive vibration
oAreas with high-radiated electrical noise, such as near fields of
transmitting antennas and areas in close proximity of arc welding
stations
Physical Layout in a Control Cabinet
When possible, cabinets housing electronic equipment should be designed with
provisions for natural or forced ventilation to facilitate heat dissipation.
Observe the following rules for cabinet installation:
oHeat generating equipment
(power supplies and other heat
inducing components) should
be installed toward the top of
the cabinet. The lower space in
the cabinet is cooler than the
top area.
oInstall heat-sensitive
components in the lower
section.
oProvide enough space between
components to allow a free flow
of air for better heat dissipation.
oProvide the maximum possible physical separation between solid state
EZTouchPLC
10 / 64
and electromechanical controls. If possible, the electromechanical
controls (motors, starters, solenoids, etc.) should be housed separately
or at the farthest point when enclosed within the cabinet.
We recommend that the unit has a minimum clear space of 2" on all sides
for adequate ventilation as shown in the image on the right.
Electrical Considerations
This section is designed to provide you with a very basic understanding of
electrical noise and how to keep it away from CPUs. Industrial plants have a
number of generators of electrical noise that are sometimes also referred to as
Radio Frequency Interference (RFI). Anytime an inductive load like a motor,
motor starter, or solenoid is turned off, it generates a burst of excess energy
that has to flow back to ground, just like electrical energy from a lightning storm
has to flow back to Earth. RFI is short bursts of electrical energy at very high
frequencies. Other sources include RF Welders or Radio Transmitters.
Effect of RFI on Electronic Automation Equipment
Electronic controls use faster and faster CPUs today. These CPUs are also
operating at 2.5V to 5VDC logic level power supply. RFI, if allowed to enter the
CPU inside, is a killer of logic. A CPU under this environment loses its brain and
behaves erratically. A smart industrial-grade CPU like the unit's card engine,
when faced with RFI, halts its operation instead of giving false outputs.
Types of RFI
RFI enters electronic controls in two ways: radiated RFI or conducted RFI. For
most practical purposes, electronic devices, unless sitting right next to a
powerful RFI transmitter, will not be affected by noise because air space severely
attenuates such interference. On the other hand, conducted RFI travels over
conductive surfaces such as power supply wires, electrical wiring of field devices,
and worst of all; improper ground planes.
Equipment cabinets usually incorporate one or two doors and/or hinged cabinet
panels. Relying on door hinges and swinging panels for a good metallic bond
between hinged parts and the main body of the cabinet does not insure
adequate grounding. Instead, the use of ground straps is recommended. It is
vital for the reliable operation of any electronic device to have any of its metallic
surfaces well grounded to Earth. This not only provides for safe operation, it will
also drain out any conducted RFI to Earth, away from the CPU's signal ground.
EZTouchPLC
11 / 64
Shielding from RFI
Shielded Cables
Power cables, I/O cables or wiring, and communication cables should all be
separate so that they do not couple the conducted RFI on any of these wires/
cables. Another path for RFI into the PLC is through its RS232 port. Hence, the
cables to this port must be shielded properly.
Equipment Cabinets
As mentioned, equipment cabinets typically incorporate one or two doors and/
or hinged cabinet panels. In addition, sub-panels may be utilized on those
electronic controls and electromechanical items that are mounted. The goal is
to create a medium for mounting the equipment and ensure grounding of the
control's chassis to it. However, the door hinges and swinging panels by
themselves are not enough to ensure adequate grounding.
Similarly, the equipment enclosures are generally either painted or anodized.
Mounting of painted or anodized enclosures to like surfaces also does not
ensure good metallic contact between the equipment chassis and cabinet. It is
imperative that the equipment chassis are grounded such as through the use of
grounding straps as illustrated below.
EZTouchPLC
12 / 64
Cabinet Wiring
The wiring of the EZTouchPLC unit to the outside the cabinet must be by
design. The wiring cannot be random in order to get the various points of the
cabinet and the electrically connected. Below are some general rules that
apply in most situations:
oProvide a separate power source to electronic controls and keep this
power bus away from any I/O power.
oThe cabinet should be wired with a safety ground (the main safety
ground wire gauge is determined by the cabinet's total current
consumption) and in accordance with all electrical code requirements.
oOnce the cabinet doors, stationary sub-panels and swing-out sub-panels
have been to the main cabinet, it is not necessary to run
safety ground wires from the equipment chassis terminals to the main
safety ground connection.
oThe safety ground terminal of each component can, and should be,
connected with the shortest wire possible, to the cabinet or sub-panel
frame.
oPlan the wiring routing. Keep all switched power in separate ducts and if
there is AC and DC power being switched, keep the wiring of each
branch separate from all wires and cables carrying low level signals.
oKeep all three phase power outside of the cabinet, but if it becomes
necessary, keep the runs as short as possible and maintain the
maximum possible distance between the three phase bus and all other
wiring.
oPrimary power leads to the control equipment (Base power terminals)
should be made with a two wire twisted cable with approximately 12
turns per foot. The length of these cables should be kept to a minimum,
and to the greatest extent possible, such cable runs should be kept
separate from other wiring.

Mounting Instructions (6 Inch Model)
The 6-inch models (6" EZTouchPLC, EZTouch I/O Micro and EZTouch I/O Nano)
must be mounted using DIN Clips. DIN Clips are metal brackets (P/N EZ-BRK-1,
package of 2 brackets and 4 screws) that attach to the panel and secure the
front panel to a mounting surface with 4 screws. Use the diagram and
instructions below to mount the EZTouchPLC unit using DIN Clips.
1. There are 4 rectangular holes in each side (two at the top and two at the
bottom) of the chassis as shown in the following figure. Choose the holes that
allow the appropriate space for your mounting panel thickness.
2. On each DIN Clip there are two metal tabs (bent inward) that fit into these
holes. Insert the two clip tabs into two holes (top and bottom) and secure the
