Warnings

Programmable control devices such as the EZTouch I/O Jr. are not fail-safe devices and as such

must not be used for stand-alone protection in any application. Unless proper safeguards are

used, unwanted start-ups could result in equipment damage or personal injury. The operator

must be made aware of this hazard and appropriate precautions must be taken.

In addition, consideration must be given to the use of an emergency stop function that is

independent of the EZTouch I/O Jr.

Installation

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

EZTouch I/O Jr.

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 unit. 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.

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 EZTouch I/O Jr. in areas where the following conditions may exist:

oEnvironmental temperatures above or below those specified by the

EZTouch I/O Jr.

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

and electromechanical controls. If possible, the electromechanical

controls (motors, starters, solenoids, etc.) should be housed separately

EZTouch I/O Jr.

or at the farthest point when enclosed within the cabinet.

We recommend that the EZTouch I/O Jr.

have 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

ElectroniccontrolsusefasterandfasterCPUstoday.TheseCPUsarealso

operating at2.5V to5VDClogiclevelpowersupply.RFI,ifallowedtoenterthe

CPU inside, is akiller of logic. ACPU under this environment loses its brain and

behaves erratically. Asmart industrial-grade CPU like the EZTouch I/O Jr. 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 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.
