Setting Ohmic Load - AEG Thyro-A Operating Instructions Manual

In order to minimise the rush current for transformers, it is possible to
alter the angle of the first half wave on potentiometer R201 TRAFO
ADAPTION.
Only for ...H1
Before adapting the transformer load:
• Switch DIP switch S1.5 to OFF

4.3.2 Setting ohmic load

• Recommendation: Set potentiometer R201 TRAFO ADAPTION to
left stop.
> T = 100ms

> Faster TAKT period is set.
> No phase angle of first half wave is set.
> Soft start time (SST) set to „0".
Soft start time SST
The SST is set at the same time. This also applies to operating mode
VAR. The soft start time has the following values depending on AN1:
* For a soft start time SST of 30 periods or 600ms, the power con-
troller remains in the SST ramp until setting time (T
600ms. The power controller then pulses without SST ramp, even if
T is less than 600ms. As soon as the power controller reaches the
