Description
In the pre-wet phase this value limits the amount of water that will
be added before the system alarms.
This is the amount of water to add during the main water phase of
the mix cycle if the system is in Preset Mode.
This is the maximum amount of water that the system will add or
calculate to add before it alarms. If the system is in CALC Mode a
check is made when the water calculation has been made. If the
system is in AUTO Mode then the system alarms when the system
reaches this value.
This is the amount of trim water to add to the recipe. Trim water is
included in the water calculation and changes the target when
calibrating the system to allow for a calibration to be made to a
batch which is not perfect.
Description
This is the dry weight of all of the materials in the mixer, including
all aggregates and cement. If this can change due to weighing
errors or moisture correction, this value should be sent from the
batch control system to allow the calculation to be done to the best
accuracy.
This is the weight of the cement added and, if entered, the Hydro-
Control log will contain the water/cement ratio for a particular batch.
This is the amount of time that the system will wait after issuing a
pre-wet done signal before alarming if it has not received the
cement in signal.
This is the amount of time that the system will mix after aggregate
addition before adding water
This is the amount of time that the system will mix after adding the
Pre-wet water before it sets the pre-wet done signal. This can be
used if it is required to mix the water into the batch before adding
cement. The cement should be controlled using the Pre-wet Done
signal and once the cement dose is complete the Cement In signal
should be activated.
This is the amount of time to mix the batch after the pre-wet water
has been added and mixed, and the Cement In signal has been
received (if used). After this time, the main water is added.
This is the amount of time to mix after the main water has been
added before signalling Mix Complete.
