The soft start time SST is set at the same time. The also applies to the operating
mode VAR. Depending on AN1 the soft start time has the following value:
AN [1°el] 30
33.7 Œ=33.7 Œ=41.2 Œ=48.7 Œ=56.2 Œ=61.5 Œ=64.5 Œ=67.4 Œ=70.5 Œ=73.5
SST [ms]
0
120
With an ohmic resistance load the poti can be turned to the left limit stop, at
Œ 30°el Thyro-A independently switches to a faster pulse operation with
T
= 5 periods without SST.
0
NOTE
In this configuration the terminal X2.7 can be used as an additional
digital "set point value" (24V d.c.). This also enables the controller to
be driven, for example, by a two-position controller.
Analog output (setting guide)
5 V / 10.0mA = 100 °el (Maximum value)
3 V / 6.0mA = 60 °el
1.5V / 3.0mA = 30 °el
1.25V / 2.5mA =
0 °el
3.2.2 Control end set point input
Potentiometer R202 allows the control characteristic to be adapted to the operation.
In central position the factor is = 1, right-hand stop = 2, left-hand stop = 0.
