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-W unit and for the control system! Unless
different transformers are used, special precautions need to be taken.
PLEASE NOTE! The CF5-W signal and power supply
grounds are common
PLEASE NOTE!
The same ground reference has to be used for
the CF5-W
unit and for the control system!
If possible keep the sensor powered up after mounting. Connect the analogue output
before measuring.

Note 1: The ground terminal is used as negative power supply DC input or AC phase
ground
(half wave rectifier).
Note 2: CF5-W 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 output 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 function manual.
Note 3: Please use voltage outputs for temperature measurements. The accuracy of temperature
measurements is valid only for units configured in voltage outputs mode.
