Information on cabling the digital input contacts is given in
Information on setting up the digital inputs with the PQF-Manager is given in
7.7.1.2.
By default, the digital inputs are disabled.
In a master-master filter arrangement, only the master that has the control over the
complete system will monitor its digital outputs. For full redundant functionality, it is
recommended to cable the digital inputs of all the units in the filter system.

Digital Outputs 1 to 6
With each digital output different filter conditions can be associated. The association
between the filter condition and the digital outputs is done with the PQF-Manager.

gives an overview of the possible PQF-Manager settings for a digital output and the
effect on the corresponding digital output relay.
