COMET T5640 Transmitters Web Sensors Power Over Ethernet
PRODUCT DESCRIPTION
Transmitters Web Sensor Tx64x with Ethernet connection are designed to measure
concentration of CO2 in the air and to measure temperature and relative
humidity of air. Devices can be powered from power supply adapter or by using
power over Ethernet – PoE.
The CO2 concentration is measured using the dual wavelength NDIR sensor with
the multipoint calibration. This principle compensates aging of the sensing
elements and offers maintenance free operation and outstanding long term
stability.
Relative humidity transmitters allows to determine other calculated humidity
variables like dew point temperature, absolute humidity, specific humidity,
mixing ratio and specific enthalpy.
Measured and calculated values are displayed on a two-line LCD display or can
be read and then processed via Ethernet interface.
The following formats of Ethernet communication are supported: www pages with
user-design possibility, Modbus TCP protocol, SNMPv1 protocol, SOAP protocol,
XML and JSON. The instrument may send also a warning message if the measured
value exceeds adjusted limit. The possible ways to sending messages: sending
e-mails up to 3 e-mail addresses, sending SNMP traps up to 3 configurable IP
addresses, sending messages to Syslog server. The alarm states are also
displayed on the web page.
The device setup can be made by the TSensor software (see
www.cometsystem.com) or using the www interface.
| **type *** | measured values | version | mounting |
|---|---|---|---|
| T5640 | CO2 | ambient air | Wall |
| T5641 | CO2 | with probe on a cable | Wall |
| T6640 | T + RH + CO2 + CV | ambient air | wall |
| T6641 | T + RH + CO2 + CV | with probes on a cable | wall |
- models marked TxxxxZ are custom – specified devices
T…temperature, RH…relative humidity, CO2…concentration of CO2 in air, CV…computed values
INSTALLATION AND OPERATION
The mounting holes and connection terminals are accessible after unscrewing
four screws in the corners of case and removing the lid.
Devices have to be mounted on a flat surface to prevent their deformation. The
external probe place in a measured environment. 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 value. All cables should
be located as far as possible from potential interference sources. Devices
don´t require special maintenance. We recommend you periodic calibration for
measurement accuracy validation.
DEVICE SETUP
For network device connection it is necessary to know new suitable IP address.
The device can obtain this address automatically from a DHCP server or you can
use the static IP address, which you can get from your network administrator.
Install the latest version of TSensor software to your PC and according to the
“Electrical wiring” (see next page) connect the Ethernet cable and the power
supply adapter.
Then you run TSensor program, set the new IP address, configure the device in
accordance with your requirements and finally store the settings. The device
setup can be made by the web interface too (see manual for devices at
www.cometsystem.com ). The default IP address of
each device is set to 192.168.1.213.
ERROR STATES
Device continuously checks its state during operation and if an error appears, it is displayed relevant code:
Err 1 – measured or calculated value is over the upper limit
Err 2 – measured or calculated value is below the lower limit or CO2
concentration measurement error occurred
Err 0 , Err 3, Err 4 – it is a serious error, please contact distributor
of the device (for devices with an external probe CO2G 10 the Err 4 indicates
that the probe is not connected)
SAFETY INSTRUCTIONS
- Humidity and temperature sensors cannot be operate and store without a filter cap.
- Temperature and humidity sensors have not to be exposed to direct contact with water and other liquids.
- It is not recommended to use the humidity transmitters for long time under condensation conditions.
- Take care when unscrewing the filter cap as the sensor element could be damaged.
- Use only the power adapter according to technical specifications and approved according to relevant standards.
- Don’t connect or disconnect devices while power supply voltage is on.
- 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.
- Installation, electrical connection and commissioning should be performed by qualified personnel only.
- Devices contain electronic components, it needs to liquidate them according to currently valid conditions.
- To supplement the information provided in this data sheet, use the manuals and other documentations which are available in the “Download” section for a particular device at www.cometsystem.com
