Description of the display window
Setting the discharge time:
Checking or, if required, changing the discharge time of the capacitor stages
is a very important menu item. The discharge time can be set between 20 and
9999 milliseconds for thyristor stages and 0 to 900 seconds for contactor stages.
Please make sure that the correct value is set, otherwise the system could be
damaged!
Confi guring the capacitor stages:
There are two ways of confi guring the capacitor stages. The stages can be con-
fi gured manually or using the auto confi guration mode.
Note
If there is no measuring voltage, the auto confi guration mode menu will not
appear.
It is important to set the stage power correctly. The stage power can be looked
up on the nameplate of the stage or the circuit diagram and then programmed
manually. In this case, skip the menu item "Activate learning mode" and indi-
vidually enter the power value for each stage.
If you want to activate the learning mode, you have to make sure that all previ-
ous submenu parameters have been set correctly.
The learning mode is activated by pressing
. Change to Yes with
and con-
fi rm by pressing
. The auto confi guration mode then automatically sets the
stage power. However, this value has to be checked after each time the learning
process is performed.
Function test:
After all values have been programmed step by step, a function test should be
performed. To do so, the controller has to be taken off the voltage supply for a
few seconds.
After re-connecting it to the voltage supply, the controller has to start automat-
ically. When reading out the CosPhi voltage in the start menu immediately after
switching on, CosPhi should be inductive. The controller starts to switch on
the individual capacitor stages after a maximum of 10 seconds (the maximum
discharge time of the thyristor stages) until the system is compensated.
The CosPhi, which can be read in the start menu, should have risen in compari-
son with former values, or it should rise when switching on additional stages. If
the compensation unit is designed correctly, the controller should compensate
the set target CosPhi after a while.
