Comet P2520 Manual

PRODUCT DESCRIPTION

Converter P2520 is designed to connect two sensors with current output into Ethernet network. Measured current (0-20mA or 4-20mA)
can be recalculated to value of physical quantity measured by the connected sensor. The converter is galvanically isolated from the
Ethernet communication lines, current inputs and power supply are not galvanically isolated.
Measured values can be read using an Ethernet connection. The following formats of Ethernet communication are supported: www
pages with user-design possibility, ModbusTCP, SNMPv1 protocol, SOAP protocol and XML. The converter 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 is made using the web interface.

INSTALLATION AND OPERATION

Devices are mounted on a flat surface with two screws or bolts. The connecting terminals are accessible after unscrewing four screws
in corner of case and removing the lid. Pass cables (external diameter 3 to 6,5 mm) through released glands and connect wires
according the schematic diagram. Wire cross-section choose from 0,14 to 1,5 mm
require 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 converter 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. TSensor software can be free downloaded from the www.cometsystem.cz.
Run the configuration software TSensor. Set the Ethernet communication interface and press Find Device button. According to MAC
address (see device label) select converter 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
next page).
To restore the converter to factory default settings use the button inside the device (see picture). Turn of
the power and unscrew upper cover of the device case. Press the button, turn on the power and keep
the button pressed for 10 sec. Close the device.

ERROR STATES

Devices continuously check its state during operation and if the error appears, it is displayed relevant code: Error 1 – parameters for
linear conversion are set incorrectly, Error 3 – measured value can not be shown at 16bit register, please use 32bit register or change
constants for conversion, Error 7 – measured value is over the upper limit, please check the current loop wiring and check the correct
function of the sensor, Error 2, Error 4, Error 5 and Error 6 – it is a serious error, please contact technical support

SAFETY INSTRUCTIONS

- Installation, electrical connection and commissioning should be performed by qualified personnel only.
- Don't connect or disconnect device while power supply voltage is on, don't use the device without the cover.
- Use the power supply according to technical specifications and approved according to relevant standards.
- Never expose the converter to higher or lower temperatures than is allowed. It is not recommended to use the
device for long time under condensation conditions.
- Don't use the device, if it doesn't work correctly.
- If it is necessary connect the device to the Internet network, properly configured firewall must be used.
- T
he 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.
- For more information, please use detailed manuals and other documentation which are available at
www.cometsystem.cz/manuals.htm or www.cometsystem.cz/software.htm.
