be done on the filter side.
Any of the two digital inputs on the PQF-Manager (Cf.

WARNING: If a function is assigned to a digital input, the same function must never be
assigned to the other digital input. Otherwise the filter may behave erratically.
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 then be restored
Then, the PQF-Manager has to be used to associate the remote control functionality with
Digital Input 1. This is done by going to the digital input setup menu and selecting
'Remote ON' for digital input 1. When this is done the filter will switch on when the switch

Refer to Section 7.9.1.4
In a multi-master arrangement, the master that has the control over the system (i.e. the
master which is operational and which has the lowest address) will monitor the digital
inputs. Therefore, in order to obtain full redundancy with filters consisting of more than
