6.15.2 Operation
Leakage currencies or deposits on the sensor can cause erroneous activation of the foam
control, resulting in an excess dosage of antifoam agent. In order to avoid such an errone-
ous activation the sensitivity of the foam sensor should be set as low as possible.
1. Reduce the sensitivity down from position „high“ until only foam is just detected.
2. Adjust the cycle time (CYCLE) and the dosing time according to your process requirements.
In mode „manual“ the pump can be switched „off“ or „on“ for continuous operation.
6.15.3 Special Notes
The foam amplifier has a response delay (5 sec) in order to avoid wrong dosage due to
splashes of liquid, etc.
If either the mode „auto“ or „manual“ is selected, the dosing counter AFOAM is automatically
activated.
