Controller- main menu
In the following text, the keys to be activated are marked black..
Example: means that the key
IN
shall be pressed. The display
- - - -
symbolizes an
identified keyboard operation, no further keyboard operation is necessary.
On the front plate of the ESTAmat PFC
Controller

control parameters, measuring values, and control characteristics can be enquired for or can be set by
means of this main menu.
By means of the key the respective menu point can be engaged.
By means of the key
the values can be reduced, or by the key

5.1. Mode
AUTO
– automatic operating mode
In the automatic operating mode, the capacitors are automatically switched in or out depending on the
demand for reactive power. The actual power factor is shown in the display. A minus in front of the
power factor means that the power factor is capacitive.
For the purpose of testing, capacitors can be switched in or out manually at any time in the automatic
operating mode.
By means of the key
steps can be switched in.
By means of the key
steps can be switched out.
As long as the decimal point flashes in the display, the re-switching blocking delay is still effective.
However, the operation of the key is stored and the capacitor step will be switched in after the re-
switching blocking delay has elapsed.
