Write Description [Setting range]
33 2033 POSITION_CHAR_
TYPE
1 O/S Denes the valve position-to-ow characteristics:
1 = linear
2 = equal % (50:1)
3 = equal % (30:1)
4 = quick open (inverse of 50:1 equal %)
5 = Camex Percentage
255 = user-dened 10-segment function
34 2034 POSITION_CHAR 10, 20, 30, 40,
50, 60, 70, 80,
90
O/S Denes the coordinates of the segment function
when 255 is set for POSITION_CHAR_TYPE.
[0 to 100, only simple decreasing can be allowed]
