6.17.3 Operation
1. Adjust the sensitivity of level sensor as low as possible to avoid unintended activation of
pump by foam. In addition the level amplifier acts using a delay time (5 sec.) to avoid unin-
tended activation of the level control due to splashing medium.
2. Adjust the reset time of the pump (PULSE) so that the number of pump cycles is minimized.
6.17.4 Special Notes
The dosing counter LEVEL will automatically be activated, whenever the modes „auto“ and
„manual“ are selected.
