INSTALLATION AND COMMISSIONING

Terminal connections

Bürkert piezo-valves type 6520 may be connected to the terminals
for actuators. Observe polarity. More detailed instructions for
connection and operation of the valves are to be found in the PTB
Test Certificate and in the Operating Manual for the valves.

DIP switch 1 to 7: Bit 1 to Bit 7

The LED flashes when the device is engaged in cyclic data
communication. The LED lights briefly on connecting the device. If
the device detectes an internal error, the LED remains lit.

Connection of the actuators
to the terminals:

Two sensors are always allocated to a valve. The sensors report the
end position of a connected process valve. The inputs can also
report other process parameters independent of the valves (e.g.
scraper end positions).

The DIP switches are only read in when the unit is switched
on.

In the PROFIBUS PA, each station is given an adress. These
addresses are set up using the DIP switches 1 to 7. The
permissible address range lies between 3 and 124.

Settings:

If switch 8 is in the ON position, the internal address is used!
This adress can be set up via the field bus.
