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 atmospheric pressure in 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. Pressure units are hPa, PSI,
inHg, mBar, oz/in2, mmHg, inH2O and kPa. Communication interface of Web Sensors is
Ethernet. Device types:

Web Sensor EPD-xxx-xxx-P devices are designed for measurement in compressed air up
to 25 bars. The removable probe is integral part of the device. It is not possible to
interchange probe between devices. Probe has connector with protection IP67.
Models marked EPD-xxx-Z are custom-specified devices. Description of these devices is
not included in this manual.
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
or probes, 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.
Before you removing probe of the Web Sensor EPD-xxx-xxx-P, make sure that pressure in
a pressure chamber and ambient pressure are equal.
Don’t use device in 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 following formats are supported:
Web pages with user changeable look and XML files
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. Also you will find there latest
firmware for your device. Do not upload to your device firmware which is not designed for
it. Unsupported firmware can damage your device.
5
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.
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
for Web Sensor EPD-T is required temperature probe Pt1000/3850ppm,
connected by shielded cable with maximum length 10m
Mounting the device
check if the equipment from previous chapter are 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 TSensor 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 point. When you installing several new devices, connect them to
the network one after another.
connect probe Pt1000 to Web Sensor EPD-T

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.

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 correctly 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.

Device setup
This chapter describes basic device configuration. There is a description of
settings using web interface.
Setup using web interface
Device can be setup using web interface or TSensor software. Web interface can be
managed by the web browser. Main page will be shown when you insert device address
into address bar of your web browser. There you find actual measured values. Page with
history graphs is shown when you click to tile with actual values. Access to device setup is
possible via tile Settings.

General
Device name can be changed using item Device name. Measured values are stored into
memory according History storage interval field. After changing of this interval all
history values will be cleared. Changes must be confirmed by Apply settings button.
