Visual display
The deviation from the set bandwidth is shown visually in the device's dis-
play. The measured voltage
highlighting shows whether the measured
voltage is above, within or below the set bandwidth . Progress of delay
time T1 is indicated by the gradual filling of the time bar . The seconds
display above this indicates the remaining delay time T1.

Setting delay time T1
Use this parameter to set delay time T1. This function delays the issuing of a
tap-change command for a defined period. This prevents unnecessary tap-
change operations if the tolerance bandwidth is exited.
To set the delay time T1, proceed as follows:
1. > Parameter > Control parameter > Press until the
desired parameter is displayed.
2. Press to highlight the position.
ð The desired position is highlighted and the value can be changed.
3. Press to increase the time or to reduce it.
4. Press .
ð The delay time T1 is set.
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.
