Section 4 Automatic operation - display of network parameter
The controller is set to automatic operation as standard. Capacitor stages are then
automatically connected in or out in order to reach the target power factor. This happens
when the required reactive power exceeds the value of the smallest capacitor stage.
In automatic operation, various network parameters can be displayed by repeatedly
pressing the "ENTER" key:

The power value specifies the total power (3-phase) assuming symmetrical load. If no
key is pressed for 60 seconds, the display automatically returns to the operating status!
Switching outputs
The switching outputs are executed as
transistor outputs.
The transistor outputs are used via an
additional auxiliary voltage (10 - 24 VDC) for
a direct triggering of thyristor switches for the
dynamic power factor correction (i.e. TSM).
Max.current for a single output: 40mA
Sum current all 6 outputs: 150mA
!
WARNING: Mixing-up of outputs and thus applying of 230 VAC on
the transistor outputs will destroy the internal transistors !
