Electrical connections
The power supply has to be connected to
and
.
is considered as system
ground. If the analogue output is connected to a controller the same ground reference
has to be used for the CF5-D unit and for the control system! Unless different
transformers are used, special precautions need to be taken.
PLEASE NOTE! The CF5-D signal and power supply
grounds are common.
NOTE! The same ground reference has to be
used for the CF5-D unit and for the control
system!
Connect the power after mounting. The analogue
output should be connected before measuring.

Note 1: The ground terminal is used as negative power supply DC input or AC phase
ground
(halfwave rectifier).
Note 2: CF5-D can deliver a voltage or a current loop for Out(1) / Out(2). To change
between voltage and current output mode the hardware jumpers are used. There is one
jumper for Out(1) and one for Out(2), so that one output can be a voltage output and the
other a current output. Both, voltage output and current outputs, can have start points 0 % (0-
10 VDC or 0-20mA) or 20% (2-10 VDC or 4-20mA). The same start point is used for both
outputs. See the user manual.
