Information about the liquid/powder level in the feed chemical container is
reported to the pump. To do so, a two-stage level switch must be fitted; it
is connected to the "Level switch" terminal.
Enables switching of a stroke rate via the "External control" jack. This aux‐
iliary frequency has priority over the operating mode stroke rate settings .
In the standard version, the "Auxiliary frequency" function is programmed
to 100 % stroke rate.
In the Extern Contact operating mode, either a series of strokes can be
triggered or an inbound series of contacts can be stepped down via the
pulse control switch by a single contact on the "External control" terminal.
To do so, the multifunctional switch has to be turned to "Extern".
