Start-up guideline
2. Function test
After all values have been programmed, 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 auto-
matically. If the cosφ voltage is read in the cosφ act. menu immediately after
switching it on, the value for cosφ should be low and inductive. After approx. 60
seconds, the controller starts to switch on the individual capacitor stages.
The cosφ, which can be read in the cosφ act. menu, should have risen in
comparison with former values, or it should rise when switching on additional
stages. If the compensation unit is dimensioned correctly, the controller should
compensate the set target cosine after a certain period of time.
Controller not configured:
If a controller which has not been configured is to be started up, the following
procedure has to be performed step by step.
1. Configuring current transformer values
For the compensation controller to function properly, all current transformer
parameters have to be set correctly. Primary and secondary current of the
transformer have to be set. These parameters can be read on the nameplate of
the current transformer. In addition, the phase allocation of the transformer has
to be set correctly. In the controller, the phase (L1, L2, L3) in which the current
transformer is integrated has to be set. This setting does not have to be made
for 3-phase measurement.
2. Setting target cosine
You can ask your energy supply company for the target cosine, which should be
set up at this point. The target cosine is by default set to 0.95 inductive.
3. Configuring the capacitor stages
The stages can be configured manually. The most important setting to pay at-
tention to is the stage power. The stage power can be looked up on the name-
plate of the stage or the circuit diagram and then programmed manually.
4. Function test
After all values have been programmed, a function test should be performed.
To do so, the controller has to be taken off the voltage supply for a few seconds.
