1) If the inner resistance of the power
supply or the processing system (PLC)
is less than 200
Ω
, a resistor of 200
Ω
to 350
Ω
must be connected to the
signal cable during adjustment.
The digital adjustment signal would
otherwise be short-circuited or
considerably damped due to insufficient
input resistors of a connected
processing system so that the
communication with the sensor would
not be ensured.
To connect the PC to the pressure transmitter,
a VEGACONNECT 2 interface converter is
required.
Connecting the PC
Plug VEGACONNECT into the standard con-
nection of the PC and connect the two-wire
cable of VEGACONNECT to the pressure
transmitter or the signal/supply cable of the
pressure transmitter.
