10.4. electrical installation devicenet
The Quickstart only describes the electrical installation of the posi-
tioner / process controller and the specification of the basic settings.
The settings of the bus communication are described in the
operating instructions for Type 8692 / 8693.
procedure:
→
Connect the positioner according to the tables.
The electrical connection module of types 8692 and 8693 features
a setscrew with nut which is used to connect the function earth (see
“Fig. 17: Connection DeviceNet”).
→
Connect the setscrew to a suitable grounding point. For
ensuring electromagnetic compatibility (EMC), make sure that
the cable is as short as possible (max. 30 cm, Ø 1.5 mm2).
When the supply voltage is applied, the positioner / process con-
troller is operating.
→
Make the required basic settings and actuate the automatic
adjustment of the positioner / process controller, as described in
the chapter entitled “11. Start-up Type 8692”.
The settings in the BUS.COMM menu item are described in
the operating instructions of type 8692 / 8693.
