Hauser 21
7.2.3 Connecting the signal cables
The signal can be transmitted using analog technology via the analog output and using
digital technology via Ethernet (Modbus protocol). The connection to the "Teqwave Viewer"
operating tool is also established via the Ethernet interface.
Connecting the analog output, digital input, signal ground and relay output
Connect the cable to the transmitter via screw terminals, terminal assignment →  19.
Connecting the Ethernet cable
Connect the Ethernet cable to the Ethernet port of the transmitter and the Ethernet port of
the computer or network.
Connecting to the "Teqwave Viewer" operating tool →  26.
7.2.4 Ensuring potential equalization
The measuring device must be included in the potential equalization. The transmitter and
sensor are connected to the same potential via the connecting cable. This potential must
be current-free.
Terminal V- is electrically connected to the transmitter housing and can be used for
potential equalization.
