Setting Up The 'Auto Restart' Function; Setting Up The 'Standby' Function - ABB PQFS Installation, Operation And Maintenance Instructions

The aforementioned functions are discussed more in detail later in this section.
For convenience, the installation settings menu also gives an overview of the installation
settings. More specifically, the following settings can be read:
Where applicable the settings for individual units in a filter system can be reviewed by
selecting the appropriate unit.
Note that the settings of the above-mentioned parameters can only be changed at the
commissioning level (Cf.

7.7.3.1 Setting up the 'auto restart' function

For setting up the 'auto restart' function, go to [/Welcome/Settings/Installation set./Start-
Stop set.]
In multi-master units these functions need to be set up in each master-unit in order to
obtain full redundancy.
The 'auto restart' function when enabled ensures that the filter restarts automatically after
a power outage if the filter was on before the power outage occurs. A time delay can be
programmed to define how long after the power returns, the filter will restart. When the
'auto restart' function is disabled, the filter will not restart automatically after a power
outage.
Remark:
By default the 'auto restart' function is enabled and the delay time is set at 5s.

7.7.3.2 Setting up the 'standby' function

For setting up the 'standby' function, go to [/Welcome/Settings/Installation set./Start-Stop
set.]
In multi-master units these functions need to be set up in each master-unit in order to
obtain full redundancy.
The 'standby' function when enabled puts the filter in standby, a preset time after the load
requirement disappears. In this condition, the IGBTs stop switching while the main
contactor remains closed (filter remains connected to the network). This way the filter
