WhatisEZT-430i? EZT-430iREVC 1.1
1 What is EZT-430i?
The EZT-430i system combines all of the features of a loop controller, video/chart recorder and data logging
system into a single/intuitive device. Email, SMS (text messaging), FTP (file transfer protocol for automated
data backup) and remote view/control (Web server/VNC server) are standard with EZT-430i and can be
accessed via LAN/WAN using a PC, tablet or smart phone device.
CSZ’s “EZT-430i” provides a 4.3”color touch screen interface with standard “Smart Device” user interface
features for single and dual loop OEM control applications. All loop configuration and runtime user access is
configurable at the device with no PC software required. OEM’s have the ability to configure runtime features
(screen availability, menus, language, etc...) to easily customize the system for their requirements. These
configurations can be imported/exported to any other EZT-430i single/dual loop device for setup (from
scratch) within minutes.
Individual high performance board level PID loop control boards (one for each loop) offer up to four control
outputs each, powerful profiling capabilities with up to three events and full auto tune functionality with high
resolution process inputs.
1.1 Features
Each of the EZT-430i loop control boards provide a single digital input that can be programmed as an
automatic program control input for run, hold or abort, a manual mode or failure transfer control input or a
program advance to next segment control input.
Each of the loop control boards also provide up to four control outputs which can be used as PID control
outputs for heat/cool, direct outputs for controlling external equipment related to the application through
software switches called events, or be programmed to act as system alarm outputs.
EZT-430i can be operated in single set point or automatic program control mode. Program entry is made
easy through the use of copy, paste and delete menu selections. Programs can be copied to the external
USB memory stick and then imported to another EZT-430i controller which eliminates the need to enter
duplicate programs into multiple systems.
Data file analysis tools make looking at historical data a simple task. Any control variable saved to the data
file can be plotted on the historical data chart for any time frame within the data file’s total time range.
The built in Ethernet functionality includes a ‘Web Server’ to provides access to all EZT-430i data (view only),
a VNC interface for remote control and monitoring and an NTS clock, all available via a local Intranet
connection (wired or wireless), or the World Wide Web using standard software like Microsoft’s Internet
Explorer.
EZT-430i provides a rich set of tools for control interaction and process monitoring. Views include single and
dual loop views, charts, alarm, automated program status as well as historical data, alarm log and audit trail
views. The menu driven interface eliminates screen “clutter” by providing an easy to use “Smart Device”
interface for interaction between the user and EZT-430i.
EZT-430i can store more than one year of data on its SD memory card. Data logging can be enabled
manually or automatically during program operation. Data backup is provided with a USB memory stick for
plug and play transfer of files to any PC running Microsoft Windows XP, Vista operating systems and via the
FTP back-up utility.
EZT-430i protects system access with 4 level security (user rights based), audit trails that document all user
activity and ensures data integrity by digitally signing all data files and audit trails to meet regulatory
requirements.

Installation EZT-430iREVC 2.1
2 Installation
The following two sections will explain how to install the EZT-430i control system. EZT-430i controllers are
pre-loaded with all operating software and firmware before leaving the factory, so it is ready to install when
you receive it. Refer to Section 2 for mounting information and Section 3 for power, signal and control wiring.
Before beginning installation, read through these sections to gain an understanding of the entire installation.
Consider the installation carefully. Plan the power, signal and control wiring before installing EZT-430i. Also
consider the cabinet space, hardware dimensions and environmental conditions. Use good wiring practices
to minimize problems that may occur due to electrical interference.
2.1 Enclosure Guidelines
EZT-430i must be installed correctly for reliable operation. The EZT-430i controller is designed for installation
within a suitable enclosure. Do not install EZT-430i outside of an enclosure. Care must be taken when
locating components to ensure that AC power wiring, contactors, starters, relays and other sources of
electrical interference are properly located to minimize their impact on the EZT-430i control system.
Particular note should be taken to the position of variable speed drives and switching power supplies. Their
input and load cables should be screened and properly grounded to a central equipment grounding point to
prevent radiated emissions from affecting EZT-430i operation.
WARNING:
To avoid potential electric shock and other hazards, all mounting and
wiring for EZT-430i must conform to the National Electric Code (NEC)
and other locally applicable codes.
Special expertise is required to install, wire, configure and operate the
EZT-430i controller. Personnel without such expertise should not
install, wire or operate EZT-430i.
CAUTION:
Prevent metal fragments and pieces of wire from dropping inside the
housing of any EZT-430i component. If necessary, place a cover
over the components during installation and wiring. Ingress of such
fragments and chips may cause a fire hazard, damage or malfunction
of the device.
When handling the EZT-430i B42 series loop control boards, use
proper ESD (electro-static discharge) handling procedures to prevent
damage to board components.
Locate EZT-430i and all related control components away from AC
power/motor wiring and sources of direct heat output such as
transformers, heaters or large capacity resistors.

EZT-430i User’s Manual
2.2 EZT-430iREVC Installation
2.1.1 Locating the EZT-430i Touch Screen Interface
It is recommended that the unit be mounted to the front panel of a steel enclosure, through an appropriately
sized opening. Proper enclosure depth is required to insure that there is adequate spacing between the rear
of the interface and the front of any high voltage devices mounted in the enclosure when the enclosure door is
closed. It is required that a minimum separation of 2” be maintained, so plan a depth to accommodate at
least 4” (102mm) behind the panel.
Proper clearance must also be maintained above, below and on both sides of the interface to allow for heat
dissipation and to facilitate mounting. A minimum of 2” is recommended. Note that additional space may be
required below and to the right of the interface (looking from rear of unit) to accommodate the
communications wiring depending upon the type of communication cables used.
2.2 Environmental Considerations
Do not subject the EZT-430i touch screen interface to operating temperatures below 0°C (32°F) or above
50°C (122°F). The operating temperature for the P41/B42 loop controls is limited from -10°C (14°F) to 50°C
(122°F). Minimum and maximum relative humidity levels are limited between 10% and 90% (non-
condensing) for the touch screen and 0 to 90% for the loop controllers. The EZT-430i touch screen interface
is to be used indoors only. The unit should not be installed where fast temperature variations may occur as
this can cause condensation of water vapor on the device.
EZT-430i should not be exposed to excessive dust, dirt, salt, direct sunlight or shock and vibration. Do not
operate the EZT-430i controller in an area where chemicals or flammable gases are present. Permitted
storage temperature extremes for the EZT-430i control system are limited to -10°C (14°F) and 60°C (140°F)
for the touch screen and -40°C (-40°F) and 60°C (140°F) for the loop controllers.
2.3 Mounting Dimensions
This section provides mounting details and dimensional information for the various components that make up
the EZT-430i control system. Note that your system may not include some of these components, and that
quantities of certain components vary depending upon the application and options ordered. Make sure that
you have all components required for your application prior to installation.
2.3.1 EZT-430i Touch Screen Interface
The EZT-430i interface is supplied with four mounting clips. All clips must be installed and properly tightened
to insure the IP65 protective rating from the front of the interface. Failure to install all mounting clips may also
affect touch screen operation. Be sure to tighten each one evenly so as not to flex the case of the unit.
