Introduction EZ12 Panel
The new EZAutomation EZ12 Panel is designed
with efficiency and versatility in mind. The new
design includes a smaller depth profile and a
streamlined design.
The new front of the panel is now one single piece
making the design more durable and wash down
proof. Further the touch screen has been
improved to be pixel level sensitive allowing full
use of all the screen for touch objects.
Finally the design has been created with Private Labeling in mind. This includes a simple and easy way to
change the EZAutomation Label to your own. Furthermore you can add an on screen private label.
The EZ12 panel also comes with the release of the new EZTouch Editor 2.0 which includes many quality
of life improvements as well as user requested functionality. This includes USB firmware upgrade, new
Setup Screen features, and on screen calibration options.

Safety Considerations
Please follow all applicable sections of the National Fire Code, National Electrical Code, and the codes of the National
Electrical Manufacturer’s Association (NEMA) to ensure maximum safety of the equipment and personnel.
Plan for Safety
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.
Local regulatory and government offices usually provide excellent help to determine which codes and standards
are necessary for safe installation and operation. Please note these codes may change from time to time, so it is
the responsibility of the user to keep up to date.
Safety Techniques
Safety isthe most importantelement ofa 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 considerations:
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 a PLC.
2) Safety Circuits
Most of the machines are installed with safety circuits, like Limit switches, Emergency stop push buttons, and
Interlocks. These circuits should always be hard-wired directly to the PLC. 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 serious injury or machine damage could result.
3) Fail-Safe Operation
Our products are not fault-tolerant and are not designed or intended for use as on-line 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 environ- mental 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 the EZ12 unit in areas where the following conditions may exist:
•Environmental temperatures above or below those specified for the EZ12 unit
•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 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.
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.

Cabinet Wiring
The wiring of the EZ12 unit 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.

EZ12 Mounting
All EZ12 panels have a new innovative mounting design. This design allows the unit to not need any
external mounting components. The mounting brackets and screws are already included in the unit. Also
the unit is designed to be very easy and simple to mount. No more trying to figure out which way to
attach DIN clips and no more looking for screws and nuts. This design has also been used in all sizes of
EZ12 units to make the design consistent and making mounting simple and easy no matter which size
panel you have.
NOTE:The maximum torque force that should be applied is 2 ½ to 3 inch-pounds.
Mounting directions:
1. When looking at the back of the unit please look at the screws in the corners of the unit. These
screws are screwed into the flip out din brackets (retainers) for the panel.
2. Unscrew the screws and you can flip out the din brackets. The 6” and 7” units have 4 (1 in each
corner), the 8” has 5 (1 in each corner and 1 at the top midpoint), and the 10” unit has 6 (1 in
each corner and 1 at the midpoint at top/bottom).
3. Then use the screws and the din brackets to mount the panel. The maximum torque force that
should be applied is 2 ½ to 3 inch-pounds.

COM1 Port
The EZ12 Series 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 unit through a PC. It serves as the default
programming port on the EZ12 Series. Since COM1 has fixed
communication parameters, you can always connect the
programming software to the PLC through the port without
needing to make different configuration changes. In addition, this
connection can be utilized to update firmware when needed.

Ethernet Port
There is an Ethernet port available on the EZ12 Series. This port enables users to add/update
programming through an Ethernet connection. It allows for both PC and PLC simultaneous
communications. It can also be used for Internet access and email alerts.
Micro SD slot
A Micro SD slot is available to allow for additional storage or data transfer. Insert a Micro SD into the slot
and it will load automatically. When finished, push against the Micro SD card to eject it from the unit.
Note: Please you cannot use Micro SD and USB drive to log data simultaneously.

USB Ports
EZ12 Series HMIs come equipped with two USB ports. The port on the left is for program upload through
a USB A to USB B programming cable.
Note: If a power cycle occurs while the USB programming cable is connected, the cable will need
unplugged and then replugged in to reestablish a connection.
The Host USB port (on the right) can connect to a USB Flash drive for program upload by simply using
our EZ Editor Software to create a USB Loader file (.hmi). It also allows the user to upgrade firmware
(.mme), enter the Setup menu (.set), and calibrate the HMI (.cal) if need be. This process benefits
system integrators and OEMs by permitting them to upgrade panels on site without the need to connect
to a computer or programming software. Please see our EZTouch Editor Software Help for detailed
instructions on this process. In addition, the Host USB can be utilized for data logging purposes in
combination with our AVG Remote File Manager Utility.
