Application area
Principle of operation
VEGATRENN 141 is an [Ex ia] separator with separate power supply 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.

Functional principle
An integrated transmitter power supply powers the connected sensor. The current signal from the sensor (4 … 20 mA) is transferred to the output linearly and galvanically separated. The instrument is HART transparent, i.e. the HART signals are transmitted bidirectionally between input and output.

Adjustment
No adjustment or configuration of VEGATRENN 141 is necessary. A parameter adjustment of the connected sensors can be carried out via the HART communication sockets behind the hinged front cover. Adjustment of the connected sensors is carried out preferably via a Windows PC with a parameter adjustment software such as PACT-ware and corresponding DTM. A VEGACONNECT interface adapter or a HART modem is necessary for connecting the PC.

Mounting

**General instructions

**

Mounting options
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 IP20, the instrument is suitable for mounting in switching cabinets. It can be mounted horizontally and vertically.

Note:
When several instruments are mounted together without space in between, the ambient temperature at the installation location of the instrument must not exceed 60 °C. Around the ventilation slots there must be a distance of at least 2 cm to the next component.
VEGATRENN 141 is a corresponding, intrinsically safe equipment and must not be installed in hazardous areas of zone 0/1. A safe operation is only ensured if the operating instructions and EU type approval certificate are observed. VEGATRENN 141 must not be opened.
A distance of 50 mm to the intrinsically safe terminals must be en-sured when mounting.

Ambient conditions
The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.
Make sure that the environmental and ambient conditions specified in chapter ” Technical data” are maintained.

Connecting to power supply

Preparing the connection
Always keep in mind the following safety instructions:

Warning:
Connect only in the complete absence of line voltage.

Connect only in the complete absence of line voltage
If overvoltage surges are expected, overvoltage arresters should be installed

Safety instructions for Ex applications

Note:
Install a disconnecting device for the instrument which is easy to access. The disconnecting device must be marked for the instrument (IEC/EN 61010).

Voltage supply
In hazardous areas you must take note of the respective regulations, conformity and type approval certificates of the sensors and power supply units.
The data for power supply are specified in chapter ” Technical data”.

Connection cable
The voltage supply of VEGATRENN 141 is connected with standard cable according to the national installation standards.
Make sure that the cable used has the required temperature resist-ance and fire safety for max. occurring ambient temperature
The sensors are connected with standard two-wire cable without shielding. If electromagnetic interference is expected which is above the test values of EN 61326 for industrial areas, shielded cable should be used. In general, cable screening is necessary in HART multidrop mode.

Cable screening and grounding
Connect the cable shielding on both ends to ground potential. In the sensor, the shielding must be connected directly to the internal ground terminal. The ground terminal on the outside of the sensor housing must be connected to the potential equalisation (low impedance).
If potential equalisation currents are expected, the connection on the processing side must be made via a ceramic capacitor (e. g. 1 nF, 1500 V). The low-frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains.

Connection cable for Ex applications
Take note of the corresponding installation regulations for Ex applications. In particular, make sure that no potential equalisation currents flow over the cable screen. In case of grounding on both sides this can be achieved by the use of a capacitor or a separate potential equalisation.

HART communication
The instrument is equipped with communication sockets in the front for connection of a VEGACONNECT or another HART handheld as well as an integrated HART resistor.

If the resistance of the connected processing system is less than 230 Ω, the digital adjustment signal is extremely damped or short-circuited. 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 integrated in VEGATRENN 141 and can be chosen through the selection of the respective terminals.
No additional resistor is required in the sensor circuit for direct connection of a HART-Master. When connecting a VEGADIS 82, the communication resistor in the VEGADIS 82 must be deactivated.

HART multidrop mode
In HART multidrop mode, the measured values are transmitted
on the same cable (bus) as the digital HART signals. An analogue 4 … 20 mA transmission is not possible, the current is limited to 4 mA. An own, unambiguous address (address range 1-15) must be as-signed to each connected sensor. In this mode, up to five sensors can be connected to one channel.

Information:
When using a HART resistor, keep in mind that there is an additional voltage loss. You can find details in chapter ” Technical data”.

Connection procedure
The pluggable terminals can be removed as needed to allow more convenient connection. To make the electrical connection, proceed as follows:

Mount the instrument as described in the previous chapter
Connect sensor cable to terminal 1/2, and where applicable, connect the shielding
Connect switched-off power supply to terminal 16/17
Connect processing circuit, e.g. from PLC to terminal 11/12 or 10/12 (with HART resistor), and shielding, 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.
