23 EXTERNAL INPUT
Setting of the desired action upon applying a control
voltage of 110...230V~ at the external input.
1 - NO
(no action)
2 - 2nd parameter set (switchover to 2nd parameter set)
This selection simultaneously activates the following
points 24...37 for programming of the values of the
2nd parameter set.
3 - External error (Display of an error message)
4 - Coupling operation parallel
(Selection of coupling operation via 2 CONTROL-MODE)
Programming of 2nd parameter set
(only active if 23 EXTERNAL INPUT is set to 2nd parameter set)
As a standard, the values of the 2nd parameter set equal the
values of the normal parameter set. Possible applications are for
example: changing of target cos-phi, switch-over of current
transformer or switch-over the switching times.
By triggering a 110...230V~ signal at the external input, the
2nd parameter set is activated with following values:
24. I-converter prim
2
25. I-converter sec
2
26. End stop
2
27. Control serie
2
28. Control principle

29. Power 1st stage
2
30. Target cos-Phi
2
31. 2nd target cos-Phi (2nd parameter set)NO/supply/Timer
2
32. 2nd target cos-Phi (2nd parameter set) nominal value
2
33. Switch on time
2
34. Switch off time
2
35. Connecting time
2
36. Disconnecting time
2
37. Discharge time
2
The programming of the 2nd parameter set is performed
equivalent to the programming of the standard parameters
(3-11; 17-19)
38 HARMONICS
Threshold value THD-V (in%). In case this value is exceeded a
message will be displayed. THD-V ist the ratio of the geometric
sum of unequal harmonics to the 1st harmonic. In any case, a
warning will be displayed. Warning via message relay will only be
executed if selected in 22.
