4 Electrical connection
The electrical connection of the device must be carried out according to the respective country specific
standards.
Incorrect installation or adjustment could cause applicationally conditioned risks.
Warning!
The instrument may only be installed if the supply voltage is switched off.
4 .1 Potential equalization - earthing
The device must be grounded.
The earthing can be carried out by the metallic process connection.
The metallic parts of the device are electrically connected with the socket of the plug M12.
4 .2 Connection cable
Use only shielded signal and measurement wires and install these wires separated from power leading
wires.
Connect the cable shield of a connected cable only at one side to earth, ideally at the installation place
of the device.
4 .3 Supply voltage
The voltage applied to the terminal contacts may not exceed the maximum permitted supply voltage
to avoid damage of the electronic.
The maximum permitted supply voltage range is:
All versions
10,5…35V
DC
All connections are reverse polarity protected.
4 .4 Switch output
Warning!
Inductive loads at the PNP switch outputs, e.g. relays, contactors or magnetic vents may only be used
with a free-wheeling diode or a RC protection circuit to avoid high voltage peaks.
Note!
For inauguration it is suggested, to deactivate all connected control devices, to avoid unwanted control
reactions.
The load at the PNP switch output will be connected to the teL of the supply voltage by a
semiconductor switch contactless and by this bounce-free.
At an activated switch state a positive signal near supply voltage is feed to the output.
At deactivated switch state and at failure of supply voltage the semiconductor switch is shut off.
The PNP switch output is current limited, overload and short circuit protected.
4 .5 Analogue output
4 .5 .1 Current output – Load resistor
A load resistor, e.g. the measuring shunt of an evaluation device, requires a minimum supply voltage.
Dependent on the connected supply voltage and the maximum output current, it results in a maximum
value for this resistor, where a correct function is still possible.
