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.

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
