The graph below shows the output dosing quantity based
on the flow rate Wq and the set dosing factor.
6.4 Control parameters
Control parameters are input variables that determine the
control functions of a controller. Different parameters
apply to each type of controller.
Dosing factor
This parameter determines the dosing rate in relation to
the flow rate.
Switch-off threshold
This parameter can be used to define a minimum flow rate
of the controlled system at which the dosing switches off
if the flow rate falls below this value.
Bumpless-Transfer
This parameter enables the current dosing capacity to be
transferred to the following operating mode or controller
mode when the operating mode and controller mode are
changed. This keeps the dosing and therefore the current
measurement stable. The function can be activated or
deactivated once or permanently.
