During work on and with the device the required personal protective equipment must always be worn. Appropriate use VEGATRENN 141 is an [EEx ia] separator with separate power sup- ply for connection of 4 … 20 mA/HART sensors in two-wire version. You can find detailed information about the area of application in chapter "Product description".
That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfill this obligation by observing the environmental instructions in this manual: • Chapter "Packaging, transport and storage" • Chapter "Disposal" VEGATRENN 141 • 4 … 20 mA/HART...
Enter the serial number manually in the app Principle of operation Application area VEGATRENN 141 is an [EEx ia] separator with separate power sup- ply for connection of 4 … 20 mA/HART sensors in two-wire version. As an associated electrical device, it ensures a galvanic separation between sensor circuit and processing circuit and thus between Ex and non-Ex areas.

4 Mounting Mounting Mounting instructions VEGATRENN 141 is designed for carrier rail mounting (top hat rail 35 x 7.5 according to DIN EN 50022/60715). Due to its protection rating of IP 20, the instrument is suitable for mounting in switching cabinets. It can be mounted horizontally and vertically.
Digital communication with the PC is then no longer possible. With low impedance processing systems, a resistor of approx. 230 Ω must be looped into the 4 … 20 mA cable. This resistor is already inte- grated in VEGATRENN 141 and can be chosen through the selection of the respective terminals. VEGATRENN 141 • 4 … 20 mA/HART...
10/12 (with HART resistor), and screen, if necessary The electrical connection is finished. Note: If several sensors should be connected in HART multidrop mode, a respective HART address must be assigned to each sensor before connecting to VEGATRENN 141. VEGATRENN 141 • 4 … 20 mA/HART...
Processing circuit (4 … 20 mA/HART, active output with looped HART resis- tor) Voltage supply Information: The connection terminals can be detached towards the front, if necessary. This can be useful when working in tight spaces or when exchanging an instrument. VEGATRENN 141 • 4 … 20 mA/HART...

HART sensors can be carried out without interrupting the measuring circuit. The resistor (230 Ω) required for this purpose is already integrated in VEGATRENN 141 (only in case of connection of terminals 10/12). The adjustment of the connected sensor is carried out via a Windows PC with a parameter adjustment software such as e.g.
Should these measures not be successful, please call in urgent cases 24 hour service hotline the VEGA service hotline under the phone no. +49 1805 858550. The hotline is manned 7 days a week round-the-clock. Since we offer this service worldwide, the support is only available in the English language. The service is free, only standard call charges are incurred.
Correct disposal avoids negative effects on humans and the environ- ment and ensures recycling of useful raw materials.
