1. Overview
This manual has been tailored to cover all of the specific features and options available on the EZT-
570S environmental chamber controller. Not all options and/or features may be available on your
particular chamber. It is highly recommended that you read this manual thoroughly and understand
all aspects of the EZT-570S controller prior to operating your chamber.
1.1 Safety Information
Note, caution and warning symbols that appear throughout this manual are to draw your attention to
important operational and/or safety information.
A“NOTE” marks a short message to alert you to an important detail.
A “CAUTION” safety alert appears with information that is important for protecting your
equipment and performance.
A “WARNING” safety alert appears with information that is important for protecting you,
others and equipment from damage. Pay very close attention to all warnings that apply to
your chamber.
1.1.1 Device Under Test (DUT) Safety Information
The environmental chamber is equipped with high heat limits and/or safety devices. These devices
are installed to protect the chamber from exceeding design limits. These devices remove power from
the chamber’s heaters only and DO NOT remove power from the device under test.
Provisions must be made by the end user to de-energize the tested device with the chamber in order
to prevent an over-temperature condition and subsequent damage to the chamber and/or device
under test. For this reason, the chamber is equipped with a DUT safety relay (24V AC/DC, 2A
maximum resistive load) that should be connected to the device’s power supply control circuit at a
minimum. This relay will open and de-energize the device under test whenever the chamber is not
operating (see Section 8.6.4.1 DUT Safety Relay Output Wiring).

1.2 About the EZT-570S
The EZT-570S environmental chamber controller combines all of the features of typical loop
controllers, video/chart recorders and data logging systems 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 the EZT-570S and can be accessed via LAN/WAN using
a PC, tablet or smart phone device.
The EZT-570S allows the chamber to be operated in single set point or automatic ramp/soak program
control modes. 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-570S controller which eliminates the need to enter duplicate ramp/soak programs into multiple
chambers.
Data file analysis tools (auto-trend) make looking at historical data a simple task. Any control variable
saved to the EZT-570S SD memory can be plotted on the historical data trend, 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-570S 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.
The EZT-570S provides a rich set of tools for control interaction and data analysis. Views include
system overviews, trends, alarms, automatic programs as well as historical data, alarm history and
audit trail views. The icon driven interface eliminates screen ‘clutter’ by providing an easy to use
‘Smart Device’ interface for interaction between the user and the EZT-570S.
The EZT-570S can store more than one year of data on its SD memory card. Data logging can be
enabled manually or automatically during ramp/soak program operation. Data backup is provided by
a USB memory stick for plug and play transfer of files to any PC or via the FTP back-up utility.
The EZT-570S 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.
The graphic displays shown in this manual are representative of those on a standard
temperature and humidity chamber. The screens and examples shown within may vary
slightly from your chamber based on installed options and type of chamber.

1.3 Touch Screen Interface
The EZT-570S display is split into two sections; the icon bar and main display area.
Figure 1-2 Touch Screen Interface
A single press of the left or right arrows will scroll program steps to the next step or screens
to the next available loop or trend. Pressing and holding the arrow keys will continue the
scrolling until the last step of the program is reached or the button is released.
Main
Display
Icon Bar
The menu icon will open the main menu for navigating to the different control
and monitoring screens. Menu items will dynamically appear providing
available options based on the system area the user is in, i.e., security, data
logging, setup, etc.
The information (help) icon will display text based help associated with the
current screen. Help is available in 28 languages based on the user selection
in the offline setup of section of the EZT-570S.
The home icon will return the user to the main view from anywhere in the EZT-
570S application.
The alarm icon will appear and flash when a new system alarm occurs.
Pressing the alarm icon will take the user directly to the alarm screen in orde
r
to view and/or reset the active alarm condition.
The light icon allows the user to turn the chamber light(s) on and off.
The left and right navigation arrows will appear on screens that provide
additional information that the user can scroll to such as the main view screen,
real time trends or program entry screen in order to cycle through each step o
f
a ramp/soak program.

1.4 Menu Navigation
The EZT-570S provides the user with the ability to select text based menu navigation, much like the
typical file menu system of a PC, as well as an icon based navigation system like that of a “smart”
device. The user can switch back and forth between the two from the System\Settings menu.
Figure 1-3 Text Based Navigation
Figure 1-4 Icon Based/Slide Navigation
The available menu items are dependent upon the options installed on the chamber. Not all of the
menu items shown may be available on chamber. The following information is provided as an
overview of the full navigational menus for the EZT-570S.
Do not use any sharp or metal objects on the touch screen as they may damage the
surface. Oil and/or solvents on hands and fingers will mar the touch screen surface.
Do not use chemicals to clean the surface of the touch screen. A soft, damp cloth is
all that is necessary.
