Auto Mode Settings
Recipe parameter Description
Local Auto Control This parameter becomes active when the recipe Control Method is
set to Auto. In normal use the Hydro-Control will work without a
problem with the Auto Parameters in the System Parameters.
However it may be necessary to set up specific parameters for
difficult mixes. This allows the system parameters to be overridden
and the local parameters to be used to control the rate of the water
addition.
Proportional Gain This parameter is used by the control mode to adjust the rate that
the water is added to the mixer.
This defines the initial speed of the water into the mixer.
Integral Gain This parameter is used by the control mode to adjust the rate that
the water is added to the mixer.
This adjusts the rate of the water addition based on the amount of
time the addition has taken. This can be used to correct an offset
at the end of the water addition without having to use excess
Proportional Gain which can cause overshoot.
Derivative Gain This parameter is used by the control mode to adjust the rate that
the water is added to the mixer.
It adjusts the rate of water addition based on the rate of change of
the difference between the current moisture and the target.
1.8
Admix Settings
Recipe parameter Description
Admix Enable This is the point in % during the main water phase that the Admix
signal will be set.
Admix Amount Not used by the Hydro-Control but appears in the Recipe. This is
the amount of admix stated in the mix design. This can be manually
input for information only.
