Parameterization and operation
4.10.8 MIN RUNTIME
Minimum ON time in pulse/pause dosing mode. The pump is
activated for this runtime at the very least. The MIN RUNTIME
must be shorter than the duration of the CONTROL CYCLE.
4.11 Displayed measurement values and variables
The following measurement values and variables are shown on
the sc1000 display and transferred via fieldbus (refer to
section Appendix B ).
