EZT-430i
What is EZT-430i? CSZ EZT-430i 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.
Future Designs “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 a
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 provide 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 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.

EZT-430i
Configurator Overview CSZ EZT-430i 2.1
2 Configurator Overview
The EZT-430i configurator is a powerful tool that allows full customization of EZT-430i. It is a program that
allows the OEM or user to set up control system options for the EZT-430i runtime application. The
configurator program will not run at the same time as the main runtime software.
The configurator can be run when the runtime software is exited and the “Exit and run configurator on next
power-up” option is selected. The next time the unit is re-powered the configurator will run.
Control functions of each loop control board can be changed while the OEM or operator is editing the
configuration of EZT-430i through the configurator program, so any equipment being controlled by the outputs
should be placed in an “off” state so that any changes will not cause an unsafe condition or damage to
equipment.
NOTE: Each time the EZT-430i configurator software is exited; the controller runtime software will run after
the unit is re-powered.
The EZT-430i configurator provides the following functionality:
•Set the number of control loops that EZT-430i will use (single/dual).
•Provide control loop configuration settings for input type, output function, set point range, etc.
•Select the type of user communications for Modbus Slave interface.
•‘Splash Screen’ name editing for custom OEM or user requirements.
•Enable/disable options for runtime menu and screen availability.
•Text editing for all system event and alarm output names.

2.2 CSZ EZT-430i Configurator Overview
2.1 Configurator Menu
The configurator menu is accessed by pressing the “Monitor” icon at the top left of the screen.
The File menu provides the exit function for the configurator.
After selecting this menu item and exiting the configurator, the
controller runtime software will run after the unit is re-powered.
The Setup menu provides access to the primary controller
setup options. These options include
the controller type
(single/dual loop), the loop control board settings, user
communications selection and the loop address utility that can
be used to automatically assign the proper communications
address to an attached loop control board.
The Calibration menu provides access to the input offset
calibration settings for the loop control boards.
The Startup menu provides access to enable and disable EZT-
430i runtime screens/menus and the desired startup view
selection.
The Tagnames menu provides access to the text editing
functions of the configurator which allow the event and alarm
names to be changed to match their use in the system. The
menu also provides access to edit the splash screen
information that is shown when the runtime application starts.

3 Configuring EZT-430i
IMPORTANT: Once all configuration settings are made, you must select “Exit” from the File menu to exit the
configurator prior to cycling power to EZT-430i. All configuration files are written upon exiting
the configurator. Do not cycle power prior to exiting the configurator or settings will be lost
and EZT-430i will not operate properly when entering the runtime application.
3.1 Loop Setup
The “Loop Setup” screen is accessed from the Setup menu. It provides the control type selection and entries
for setting the loop names and display units.
The Control Type selection sets the number of loop control boards that will be attached to EZT-430i, one
(single loop) or two (dual loop). When the EZT-430i runtime application is started, EZT-430i will automatically
configure all loop view displays, charts and available data log point selections based on the control type
selection and individual loop setup.
The Loop Name fields are used to enter a specific name for each control loop, up to 11 characters in length.
This name will be used throughout the EZT-430i runtime application and can be used to provide a more
detailed description as to the function of the loop in the application. Default tag names are LOOP 1 and
LOOP 2.
The Units fields are used to enter the engineering units for the loop with up to four characters maximum.
This value is shown on the single and dual view loop screens in the EZT-430i runtime application. When the
loop input type selection is set for temperature, the field will be fixed at either “C” or “F” based on the units
selection for the loop under loop setup. If the loop input type is set for a linear input type (0-10V or 4-20mA
for example), the engineering units can be edited and changed to the required units for the measured process
value.

A.2 CSZ EZT-430i Configuring
3.2 Loop Address Utility
In order for EZT-430i to properly communicate with each of the loop control boards, they must be configured
for the proper communications address. The factory default communication settings of the loop control
boards are set for a communications address of one, which correspond to the proper settings for loop 1. For
a single loop EZT-430i control system, no further settings are required. Simply connect the communications
wiring between the control board and the EZT-430i interface, and the system is ready to go.
For a dual loop EZT-430i control system, one of the control boards must be set for address two which
corresponds with loop 2 of EZT-430i. If a display module is not available to connect to the loop control board
in order to set its address, the Loop Address Utility can be used. It is accessed from the Setup menu.
In order to use the utility, only one loop control board can be connected to EZT-430i at a time. Since the
default address of all control boards are 1, if more than one was connected, they would both respond to the
same command which would cause them both to be set to a different address. If both loop control boards are
connected, disconnect the communications wiring from the loop control board that you DO NOT want to set
the address on. An alternative is to remove power from the loop control board rather than disconnecting the
communications wiring.
With only one loop control board powered on or connected to EZT-430i via the communications link, press the
“Assign to Loop” button for the loop that you want to assign the control board to. The utility will begin
scanning for the loop control board and set its address to the proper address once found. If the utility fails to
set the address, check the wiring to insure it is properly connected. If the loop control board has been
previously used for another application, it may be possible that the address or other communications settings
have been changed, which prevent the utility from working. In this case, a display module must be connected
to the loop control board to set the proper communications settings:
Address: 1 or 2 (for loop 1 or loop 2)
Baud rate: 9600
Parity: Even
IMPORTANT: The loop input number corresponds to the communications address that must be set in the
loop control board for EZT-430i to access it properly. If the communications address is not
set properly in the loop control, EZT-430i will not be able to communicate with it, or may
communicate with the wrong loop control and assign the incorrect set points and control
parameters to it.
