32 Pressure transmitter D81

Ri < 250 Ω

4 ... 20 mA

Setup

5.5 Adjustment with PC directly on the sensor

(electronics versions I, K and L)

For connection of the PC to the sensor, the interface converter VEGACONNECT 2 is required.

Connection of the PC to the sensor

Insert VEGACONNECT into the serial interface of the PC and insert the two-wire cable of

VEGACONNECT into the CONNECT socket of the sensor.

Connection of the PC to the signal cable

Connect the two-wire cable of VEGACONNECT 2 to the signal cable leading to the sensor.

Connection configuration with pressure transmitter directly on active PLC

(electronics versions I, K and L)

• Two-wire technology, power supply from active PLC.

• Output signal 4 … 20 mA (passive).

• Adjustment with PC, HART

handheld or adjustment insert located in the sensor or in the

external connection housing.

If the resistance of the processing system (PLC)

connected to the 4 … 20 mA signal output is less

than 200 Ω, a resistor of 250 Ω must be connected

to the connection cable during adjustment.

The digital adjustment signal would be considerably

damped or short-circuited through insufficient

resistance of a connected processing system, and

digital communication with the PC would not be

ensured.
