Introduction
This chapter provides basic information about device. Before starting please read
this manual carefully.
The Web Sensor devices are designed for measurement of temperature, relative humidity
and carbon dioxide concentration of air without aggressive substances. Measured quantities
are according device type. Devices with relative humidity measurement can show one of
computed quantities: dew point temperature, absolute humidity, specific humidity, mixing
ratio and specific enthalpy. Temperature units are °C or °F. Communication interface of
Web Sensors is Ethernet. Device types:

Models marked TxxxxZ are custom-specified devices. Description of these devices is not
included in this manual.
A multiple point CO2and temperature adjustment procedure leads to excellent CO2
measurement accuracy over the entire temperature working range; this is a must for process
control and outdoor applications. The dual wavelength NDIR CO2sensing procedure
compensates automatically for ageing effects. The CO2module is highly resistant to pollution
and offers maintenance free operation and outstanding long term stability.
Measured values can be read in „SLOW mode“ (filtered, averaged) or in „FAST mode“
(current values without averaging). „SLOW mode“ has advantages in applications like
climate control because of filtering short time peaks. As an example exhaled air from an
employee passing the sensor could affect the climate control negatively with a short response
time because the control would trigger a change of the ventilation based on this one-time
measurement. On the contrary in „FAST mode“ no software filter is used for calculating the
output value. This fact adds a noise of typ. ±30ppm which has to be considered in terms of
accuracy. Of principle measurement is the measured value of CO2concentration depends on
the value of air pressure - altitude at the installation site. For this reason, it is suitable for
accurate measurement to set the altitude of the installation site.
After power up of the device starts internal test. During this time (about 20s) LCD display
shows (----) instead of CO2concentration value. Web pages show n/a.

General safety rules
The following summary is used to reduce the risk of injury or damage the device.
To prevent injury, please follow instructions.
The device can be services only by a qualified person. The device contains no
serviceable parts inside.
Don’t use the device, if it doesn’t work correctly. If you think, that the device is
not working correctly, let check it by qualified service person.
It’s forbidden to use the device without the cover. Inside the device can be a dangerous
voltage and may be risk of electric shock.
Use only the appropriate power supply adapter according to manufacturer specifications and
approved according to relevant standards. Make sure, that the adapter does not have
damaged cables or covers.
Connect the device only to network parts approved according to relevant standards.
Connect and disconnect the device properly. Don’t connect or disconnect Ethernet cable, if
the device is powered.
The device may be installed only in prescribed areas. Never expose the device to higher or
lower temperatures than is allowed. The device has not improved resistance to moisture.
Protect it from dripping or splashing water and do not use at areas with condensation.
Devices are not designed for locations with chemically aggressive environment. Temperature
and humidity sensors must not be exposed to direct contact with water or other liquids. It is
not allowed to remove the sensor cover to avoid any mechanical damage of the sensors.
Don’t use device in potentially explosive environments.
Don’t stress the device mechanically.
Device description and important notices
This chapter contains information about basic features. Also there are important
notices concerning to functional safety.
Measured values can be displayed on LCD display or can be read using an Ethernet
connection. The visual indication of CO2concentration is provided by three-color LED.
The following formats are supported:
Web pages
Current values in XML and JSON format
Modbus TCP protocol
SNMPv1 protocol
SOAP protocol

The device can also be used to check measured values and if the limit is exceeded, device
sends warning messages. Possible ways to sending warning messages:
Sending e-mails up to 3 e-mail addresses
Sending SNMP traps up to 3 configurable IP addresses
Displaying the alarm status on web page
Sending messages to Syslog server
The device setup can be made by the TSensor software or web interface. TSensor software
can be free downloaded from the manufacturer’s website. Latest firmware can be obtained
from the technical support. Do not upload to your device firmware which is not designed
for it. Unsupported firmware can damage your device.
Device does not support powering over Ethernet cable (PoE). PoE splitter must be used.
Compatible PoE splitter can be purchased as optional accessories. Splitter must have 12V
output with approximately 1W.
Reliability of warning messages delivering (e-mail, trap, syslog), depends on
actual availability of necessary network services. The device should not be used
for critical applications, where malfunction could cause to injury or loss of
human life. For highly reliable systems, redundancy is essential. For more
information please see standard IEC 61508 and IEC 61511.
Never connect the device directly to the Internet. If it is necessary connect the
device to the Internet, properly configured firewall must be used. Firewall can
be partially replaced by the NAT.

Getting started
Here you can find information necessary to put newly purchased equipment to
operation. This procedure is only informative.
What is needed for operation
To install the unit you need to the following equipment. Before installation check if it’s
available.
Web Sensor Tx5xx device
power supply adapter 9 - 30V/200mA
RJ45 LAN connection with appropriate cable
free IP address in your network
Mounting the device
check if the equipment from previous chapter is available
install the latest version of TSensor software. This software is used to all device
settings.
TSensor software can be free downloaded from the manufacturer’s website.
Software can be also supplied on CD. Device configuration can be made using
web interface. For web configuration is not TSesnor software necessary.
contact your network administrator to obtain following information for the
connection to the network:
IP address:
_____._____._____._____
Default gateway:
_____._____._____._____
DNS serer IP:
_____._____._____._____
Subnet mask:
_____._____._____._____
check if there is no IP address conflict when you connect the device into
network for the first time. The device has from factory set the IP address to

192.168.1.213. This address must be changed according to information from the
previous step. When you installing several new devices, connect them to the
network one after another.
connect the Ethernet connector
connect the power adapter 9 - 30V (e.g. 12V/200mA)
LEDs on LAN connector should blink after connecting the power and LCD
start showing measured values.
Device settings
run configuration software TSensor on your PC
switch to an Ethernet communication interface
press button Find device...

the window shows all available devices on your network
click to Change IP to set new address according to network administrator
instructions. If your device is not listed, then click Help! My device wasn’t
found! Then follow the instructions. MAC address is on product label. The
device is factory set to IP 192.168.1.213.
gateway may not be entered if you want to use the device only in local network.
If you set the same IP address which is already used, the device will not work
properly and there will be collisions on the network. If the device detects a
collision of IP address then reboot is performed automatically.
after changing IP address device is restarted and new IP address is assigned.
Restart of the device takes about 10 seconds.
connect to device using TSensor software and check the measured values. Set
the other parameters (alarm limits, SMTP server, etc.). Settings are saved after
click on button Save changes.

Checking functions
The last step is to check measured values on the device website. In the address bar of the
web browser, enter the device IP address. If the default IP address was not changed, then
insert http://192.168.1.213.
Displayed web page lists actual measured values. If the web pages are disabled, you can see
text Access denied. In the case of measurement error a text Error is shown instead value.
