The electrical requirements of the digital inputs are as discussed in

Once the cabling has been finished,
· The auxiliary fuse box may be closed
· The filter top cover may be replaced including the connection of the PQF-
Manager to the master unit
· 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.
