Electrical Connections Of Filter Options And Accessories - ABB PQFM Instruction Manual

Figure 66: Cabling diagram for implementing start and stop on digital input 1
Once the cabling has been finished, the power to the filter may be restored.
Remarks:
- The implementation of local start/stop buttons does not inhibit the usage of the
start/stop function on the PQF-Manager.
- When remote control functionality is implemented (cf.
time as local start/stop buttons, the remote control has priority over the local
start/stop buttons. When the local start/stop command has to be given,
deactivate first the remote control functionality by navigating with the
PQF-Manager to the digital input setup menu and setting the digital input
associated with the remote control to 'Disabled'.
- Note that in a multi-unit filter system in which more than one master system is
present, the digital inputs of all masters have to be set up and cabled in the same
way to obtain full redundancy.

6.13 Electrical connections of filter options and accessories

Filter options must be ordered in advance and are cabled in the factory. For these
options, refer to the wiring diagram provided with your filter to identify the electrical
connections if desired. For some accessories however, the customer may have to do the
cabling on site. These accessories include:
- The connection of the USB or Ethernet cable used for PQ-Link software
communication (optional)
- The connection of the Ethernet cable used for Modbus TCP communication
(optional)
- The connection of the RS485 Modbus RTU adapter (optional)
The connections of the aforementioned accessories are discussed next.
