8.4.4.1 Display for bleeding action
If the current measured conductivity value exceeds the permanently set upper bleeding
threshold W+, the bleeding process is started.
Fig. 8.23
If the conductivity falls consistently short of the set lower bleeding threshold W-, the contact
for the bleeding is deactivated and the unit switches back to the normal operation display.
By disconfirming the release you can abort the bleeding process. If after restarting the
release, the current conductivity lies under the top bleeding threshold, the next bleeding
process will be delayed until the threshold W+ is exceeded again.
If the bleeding regulator is set for a positive controlling direction, the regulation process is
reversed. That means: If the conductivity falls short of the low bleeding threshold W-, the
bleeding starts. When reaching the top threshold W+ the bleeding stops again.

„BLEEDING" (currentlyoperating condition) is
