PQF-Manager setup for digital input: Edg
(a) (c)
ON/OFF
Remarks:
(a)
: In order for this function to be activated, the PQF-Manager has to be set up accordingly.
To do this, navigate to [/Welcome/Settings/Customer set./Digital Inputs]
(b)
: When using the Edge ON function the filter can only be switched on by applying voltage to the digital
input considered. It is therefore recommended in that case to configure and cable the second digital
input as Edge OFF.
(c)
: When using this function, the filter stop and start can be controlled by one digital input leaving the
other one available for an additional remote control or switching between main and auxiliary settings.
Information on cabling the digital input contacts is given in
Information on setting up the digital inputs with the PQF-Manager is given in
7.9.1.4.
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.
9 gives an overview of the possible PQF-Manager settings for a digital output and the
effect on the corresponding digital output relay.

The auxiliary power is present in the main filter
enclosure and the main controller is communicating
with the PQF-Manager
The active filter is 'on' (IGBTs switching) or in
'standby' (main contactor closed but IGBTs not
switching)
The active filter is running under full load condition
The filter is ON or is in the startup procedure, or it is
stopped in fault condition but will restart as soon as
the fault has disappeared
The filter temperature limit has been reached and
the filter is derating itself to run at a safe
temperature
The filter is in standby
The main active filter settings are activated
Filter starts on first rising
edge, stops on second
rising edge etc.
