9.1

What this chapter contains

This chapter contains the user operating instructions for the active filter. It is assumed
that the filter has been installed and commissioned correctly (cf. previous chapters). The
following operations are discussed:
Note that in the context of this manual, the PQF-Manager is used to operate the filter.
Background information on the PQF-Manager can be found in
An alternative way to operate the filter is using Modbus communication. Refer to
document "2GCS212012A0050-RS-485 Installation and Start-up guide" for more
background information on this subject and to the information provided by your system
integrator.
WARNING: High AC and DC voltage may be present in the filter enclosure. Do not
operate the unit with the protective panels removed. Do not touch any filter parts
unless you have ascertained that they do not carry dangerous voltage levels.
9.2

Starting and stopping the filter

The PQFS contains a main contactor that is controlled by the filter controller. The main
contactor should never be activated manually for normal filter operation.
WARNING: Under no circumstances close the main contactor manually. Failure to
adhere to this guideline may result in physical injury and/or in filter damage.
Normally, the commissioning engineer has set up the filter and the desired filter
requirements. As a result, the user only has to start and stop the filter. Detailed
information on the filter start/stop menu can be found in
