Cabling Of Remote Control Functionality - ABB PQFS Installation, Operation And Maintenance Instructions

The remainder of this section gives examples of how to cable different functions, i.e.
Case 1: Cabling of remote control functionality.
Case 2: Cabling of alarm functionality.
Case 3: Cabling of warning functionality.
Case 4: Cabling of the digital output contacts to monitor other filter operation modes
than warnings and alarms.
Case 5: Cabling of main/auxiliary control functionality.
Case 6: Implementation of local start/stop buttons.
It is recommended that for additional functions that are cabled to the PQFS, a connector
approach is used such as is the case for the internal communication and PQF-Manager
power supply.
WARNING: Before cabling any of the circuits discussed below, switch off the power
supply to the filter. When the filter has already been installed on site, this is done by
opening the protection system located just upstream of the filter and opening the
auxiliary fuse box present in the filter. Wait at least 25 minutes to allow for the DC
capacitors to discharge when the filter has been connected to the network before.
Failure to do so may result in the lethal injury or death.
After making and verification of all the electrical connections
−
Close the auxiliary fuse box of the filter units starting from the last slave and
ending with the master unit.
−
Restore the top cover(s) of the filter units including the connection of the PQF-
Manager to the master unit
−
The power to the filter may then be restored.

6.12.1 Cabling of remote control functionality

The PQFS has the possibility to be controlled by remote control. An example of this
approach is a drive that is switched on at a location and which automatically gives a start
command to the filter. When the drive is then stopped, the drive sends automatically a
