Info
See "P(ID) controller" section.
See "P(ID) controller" section.
With every Hold, the I-component is set
to zero. Although Hold can be
deactivated in field S2, this does not
apply for Chemoclean and timer!
See "P(ID) controller" section.
The setting is required depending on the
control deviation (upward or downward
deviation, see "Chemoclean function"
section).
Pulse length e.g. for solenoid valve,
pulse frequency e.g. for solenoid dosing
pump, see "Actuating signal outputs"
section.
Curr = current output 2 can only be
selected if O2 = Contr.
This field only appears if pulse length is
selected in R237.
If pulse frequency is selected, R238 is
skipped and entries continue with R239.
This field only appears if pulse
frequency is selected in R237. If pulse
length is selected, R239 is skipped and
entries continue with R2310.
This field only appears if pulse length is
selected in R237.
When you select the basic load, you
enter the desired dosing quantity.
100% basic load corresponds to:
– Constantly on for R237 = len
– Fmax at R237 = feq
– 20 mA at R237 = curr
