The Modbus adapter interface is connected at this location. The output of the interface is
an RS-485 socket. The interface is described in the Modbus interface manual.
6
The PQF-Manager communicates with the main controller through a CAN bus. This bus
consists of three terminals, i.e.:
The CAN bus wiring terminates into the PQF-Manager connection plug and is
subsequently routed to the main control (Cf.
communications only.
7
The PQF-Manager power supply is provided by the filter itself. The corresponding
terminals on the PQF-Manager labeled "Power supply" are connected to the PQF-
Manager connection plug.
For information on how to cable external systems (e.g. remote control, Modbus interface)
