Parameter

Control deviation

Continuous blowdown valve

Proportional

band Pb

Pb

> higher

Large offset

Responds slowly

< lower

Small offset

Responds quickly and may open/close
continually

Example:

Measuring range 0 - 6000 µS/cm
Setpoint SP = 3000 µS/cm
Proportional band Pb = +/- 20 % of setpoint = +/- 600 µS/cm
With the measuring range and setpoint mentioned above, the proportional band is
then +/- 600 µS/cm or in the range 2400 µS/cm to 3600 µS/cm.

Reset time

Ti

> higher

Slow correction of deviations

Responds quickly

< lower

Fast correction of deviations, the control
loop may tend to overshoot

Responds slowly

Neutral

zone

> higher

Correction of deviations starts with a
delay

In this range, the control point does
not change.
Responds only if the control
deviation is larger than the neutral
zone.

< lower

Correction of deviations starts rapidly

Valve runtime

Establish the real valve runtime, e.g.
from Closed to Open (0 - 100 %).
