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 an Touch
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 Touch Jr. 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.

7 / 29
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 Touch Jr. in areas where the following conditions may exist:
oEnvironmental temperatures above or below those specified by the
Touch 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

8 / 29
or at the farthest point when enclosed within the cabinet.
We recommend that the Touch 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
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 Touch 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.

9 / 29
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 unit 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.

10 / 29
Cabinet Wiring
The wiring of the Touch Jr. to the “fiel” outside the cabinet must be by
design. The wiring cannot be random in order to get the various points of the
cabinet and the “fiel” 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 “strappil” 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
Before mounting your new Touch Jr. unit, please verify you have the necessary
items:
·Touch Jr. unit
·4 DIN clip assemblies
·a Phillips #1 screwdriver (or equivalent)
When ready to proceed:
1. Prepare the DIN clip assembly first by placing the nut on the screw.
Insert the screw into the DIN clip in the non-threaded end first using the
Phillips #1 screwdriver if necessary. Leave a gap between the DIN clip
and the head of the screw.
2. After ensuring the cut-out is sized properly and allows for adequate
ventilation, place the Touch Jr. unit into the cut-out horizontally.
3. Once in place, use the hooks on the DIN clip to locate the DIN clip
assembly onto the side of the Touch Jr. unit. Tighten the screw into
place. Then rotate the nut until it is snug against the DIN clip to
prevent it from vibrating loose. Repeat this process with the other 3
DIN clip assemblies until the Touch Jr. unit is secure.

Serial Port (COM1)
The Touch Jr. model has a built-in serial port (COM1 PORT) located on the 9-pin
D-Sub connector. COM1 PORT is an RS-232 port which requires an appropriate
RS-232C cable (P/N: EZ-PGMCBL) for programming the Touch Jr. through a PC. It
serves as the default programming port on the Touch Jr. Since COM1 has fixed
communication parameters, you can always connect the programming software
to the Touch Jr. through the port without needing to make different
configuration changes.
PLC Port
The Touch Jr. has a second built-in serial port located on the 15-pin D-Sub
connector. This serial connector is used for PLC communications and can be
used for RS232, RS422 and RS485 communications. Most PLCs connect to the 15-
pin D-Sub with a cable specific to the PLC type.

Transfer a Project
After a project is complete, the next step is to transfer the project to the Touch Jr.
When editing projects online, programming information is automatically sent to
the Touch Jr. unit once the project is saved. When editing in an off-line mode, the
project information will need to be transferred. More details about the transfer
process is available in our EZ Panel Enhanced Software Manual. The basic
instructions are as follows:
From the Project drop down menu, select File > Transfer to Panel. A dialog
box similar to the one below will appear.
There are two connections available to transfer the program.
Serial Port (COM1):
1. Verify the RS-232C cable (P/N: EZ-PGMCBL) is connected between the
unit and the PC. In the absence of an RS-232 port on the PC, a USB to
RS-232 converter may be used to connect the programming cable to the
PC.
2. Select Serial (COM1) as method of transfer. And then click Start.
