Setting control response T1
The control response T1 can be set to linear or integral.
With linear control response, the device responds with a constant delay time
regardless of the control deviation.
With integral control response, the device responds with a variable delay
time depending on the control deviation. The greater the control deviation
(ΔV) in relation to the set bandwidth (B), the shorter the delay time. The de-
lay time can therefore be reduced down to 1 second. This means that the
device responds faster to large voltage changes in the grid. Regulation accu-
racy improves as a result but the frequency of tap-changes increases too.

1 "Delay time T1" parameter
To set the control response T1, proceed as follows:
1. > Parameter > Control parameter > Press until the
desired parameter is displayed.
2. Press or to set the response you want.
3. Press .
ð The control response T1 is set.
Setting delay time T2
With this parameter, you can set delay time T2. Delay time T2 is used to
compensate for large control deviations faster.
