Figure 7.4
Switching point characteristics with hysteresis area larger than the overflow limit
The measuring range between the upper hysteresis limit and the overflow position is illustrated
by the dashed lines. The SSC1 (Switching Signal Channel 1) process data changes its status
when the position measurement is exceeded at 1600 and never greater than 1750. The mea-
suring range between 1600 and 1750, which can never be reached during live operation, is
shown here using dashed lines.
Position
sector 1
White section = area outside the hysteresis areas and the setpoints
Position
sector 2
Yellow section = hysteresis area of the smaller setpoint
Position
sector 3
Red section = area between setpoint 1 and setpoint 2
Position
sector 4
Yellow section = hysteresis area of the larger setpoint
