5 Connecting to power supply

VEGAPULS 21 • Two-wire 4 … 20 mA/HART

58351-EN-191014

5.4 Switch-on phase

After connection to the power supply, the device carries out a self-

test:

•

Internal check of the electronics

•

Output signal is set to failure

The current measured value is then output on the signal cable.
