Web Sensor with PoE – two channels with binary inputs
QUICK START MANUAL
P8552 P8652 P8653
PRODUCT DESCRIPTION
Web Sensors P8552, P8652 and P8653 with Ethernet connection are designed to
measure temperature and relative humidity of the air.
The devices are equipped with two connectors for connection of the temperature
and humidity external probes and three binary inputs for two states signals.
The dry contact or two-state voltage signal can be connect to the binary
input. The first binary input of the sensor P8653 is intended for the flood
detector LD-81 connection. The devices are powered from an external power
supply adapter. Web Sensors P8652, P8653 supports also Power over Ethernet
(PoE).
Measured values can be read and then processed using an Ethernet connection.
The following formats of Ethernet communication are supported: www pages with
user-design possibility, Modbus TCP protocol, SNMPv1 protocol, SOAP protocol
and XML. The instrument may send also a warning message if the measured value
exceeds adjusted limit. The messages can be sent up to 3 e-mail addresses or
to Syslog server and can be sent by SNMP Trap too. The alarm states are also
displayed on the websites. The device setup can be made by the TSensor
software (see www.cometsystem.com) and using
the www interface.

INSTALLATION AND OPERATION
The devices are designed for wall mounting with two screws or bolts. Pay
attention to the location of the device and probe. Incorrect choice of working
position could adversely affect accuracy and long-term stability of measured
values. The Web Sensor with attached DSRH/C or DST/C probe install always
vertically with the sensor cover downwards. Devices don´t require any special
operation and maintenance.
We recommend you periodic calibration for measurement accuracy validation.
DEVICE SETUP
Contact your network administrator to obtain necessary information for the
device connection into the network (IP address, default gateway, subnet mask)
and check if there is no IP address conflict when you connect the device into
network for the first time. IP address of each device is set by manufacturer
to 192.168.1.213. Install the latest version of TSensor to your PC, connect
the Ethernet cable and connect the power supply (see “Device connection
procedure” on the other side of this data sheet).
Run the configuration software TSensor. Set the „Ethernet“ communication
interface and press „Find Device” button. According to MAC address (see device
label) select device for configuration and by „Change IP Address” button set
new address according to network administrator instructions. Gateway IP
address may not be entered if you want to use the device only in local
network. After changing of IP address the device is restarted and new IP
address is assigned. Restart of the device takes about 10 seconds.
The device setup can be made by the web interface. Main page will be shown
when you insert device address into address bar of your web browser. Access to
device setup is possible via tile Settings (see user manual).
To restore the Web Sensor to the factory default settings use the button
inside the device.
Turn of the power supply and press the button (see picture). Turn on the power
supply and keep the button pressed for 10 sec.
ERROR STATES AND TROUBLESHOOTING
Device continuously checks its state during operation and if an error appears, the device sends the error message. The detailed description of the error messages is given in the user manual Chapter “Troubleshooting”.
SAFETY INSTRUCTIONS
- Don’t connect or disconnect thermometers while power supply is on.
- Installation, electrical connection and commissioning should be performed by qualified personnel only.
- Use the power adapter according to technical specifications and approved according to relevant standards only.
- The external probe cable should be located as far as possible from potential interference sources.
- If it is necessary connect the device to the Internet, properly configured firewall must be used.
- The device should not be used for applications, where malfunction could cause to injury or damage to property.
- Devices contain electronic components, it needs to liquidate them according to legal requirements.
- To supplement the information provided in this data sheet, use the manuals and other documentations which are available at www.cometsystem.com
