4Quick-starting the Device
This section outlines the steps needed to setup the EZ3-TouchPLC Modular and get it started. This is not
intended to explain specific details needed to start your system. Rather, it provides a quick guide to give a broad
picture of what is needed to power-up EZ3-TouchPLC Modular 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:
-EZ3-TouchPLC Modular unit
-USB Programming cable*
-2.5mm blade screwdriver for I/O wiring (P/N EZIO-SCDRV)*
-Programming Software: EZ Series 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
EZ3-TouchPLC Modular terminals.
Step 2: Connect Power
Connect the power input wires to the EZ3-TouchPLC Modular power terminals as outlined in the Powering the
EZ3-TouchPLC Modular 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 Touch Panel Editor and create 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

5Installation
Guideline
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 an EZ3 Series TOUCHPLC.
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 EZ3 Series TOUCHPLC. These devices must be
wired in series so that when any one device opens, the PLC 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.

EZ3-TouchPLC
Modular
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 enviro nmental 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 EZ3 Series TouchPLC in areas where the following conditions may exist:
Environmental temperatures above or below those specified by the EZ3 Series TouchPLC
Prolonged exposure to humidity and liquids which may be sprayed or splashed on the equipment
Dusty environments where airborne particles may accumulate on equipment causing reduction of heat
dissipation and reduction in effective electrical spacing between components
Areas with excessive vibration
Areas 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:
Heat 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.
Install heat-sensitive components in the lower section.
Provide enough space between components to allow a free flow of air for better heat dissipation.
Provide the maximum possible physical separation between solid state 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 EZ3 Series TOUCHPLC have a minimum clear space of 2" on all sides for adequate
ventilation as shown in the image on the left.
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 EZ3 Series TOUCHPLC 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

Page 10 of 44
EZ3-TouchPLC
Modular
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 ground 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.
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.
Cabinet Wiring
The wiring of the EZ3 Series TOUCHPLC to the “field” outside the cabinet
must be by design. The wiring cannot be random in order to get the
various points of the cabinet and the “field” electrically connected.
Below are some general rules that apply in most situations: Provide a
separate power source to electronic controls and keep this power bus
away from any I/O power.
The 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. Once the cabinet
doors, stationary sub-panels and swing-out sub-panels have been “strapped” to the main cabinet, it is not
necessary to run safety ground wires from the equipment chassis terminals to the main safety ground connection.
The safety ground terminal of each component can, and should be, connected with the shortest wire possible, to
the cabinet or sub-panel frame. Plan 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.
Keep 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.
Primary 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.

7Programming
PLC Operation Sequence
A good understanding of the EZ3-TouchPLC Modular CPU operating sequence will
help you achieve the proper control for your equipment or process. The flow chart
on the left shows how the CPU controls all aspects of system operation.
Power-up Initialization
On power-up, the CPU initializes the internal electronic hardware. It also checks
if all the memories are intact and the system bus is operational. It sets up all the
communication registers. If all registers are go, the CPU begins its cyclic scan
activity as described below.
Read Inputs
The CPU reads the status of all inputs, and stores them in an image table. Image
Table is EZ3-TouchPLC Modular internal storage location where it stores all the
values of inputs/outputs for ONE scan while it is executing ladder logic. The CPU
uses this image table data when it solves the application logic program.
Execute Logic Time
This segment is also called Ladder Scan. The CPU evaluates and executes each
instruction in the logic program during the ladder scan cycle. The rungs of a ladder
program are made with instructions that define the relationship between system
inputs and outputs. The CPU starts scanning the first rung of the ladder program,
solving the instructions from left to right. It continues, rung by rung, until it solves
the last rung in the Main logic. At this point, a new image table for the outputs is
updated.
Write Outputs
After the CPU has solved the entire logic program, it updates the output image
table. The contents of this output image table are written to the corresponding
output points.
Immediate Inputs/Outputs
There is a possibility that an input changes after the CPU has read the inputs. If you have an application that cannot
wait until the CPU returns for the next input scan, you can use Immediate Instructions. These in structions do not
use the status of the input from the image table to solve the application program. The Immediate Instructions
immediately read the input status directly from I/O modules and update the image table with appropriate status
of input module read. Similarly, Immediate Output instructions do not wait for the CPU to complete the ladder
scan. Immediate outputs are directly written to the image table and Outputs are updated accordingly.
Subroutines
The CPU executes subroutines when called for in the ladder program. These subroutines are useful in performing
the same logic operation time and time again just upon one call so you do not have to repeat the rung logic over
and over again.
