The
2-Step Addition
option is used in Preset and CALC Mode and changes the Main Water
Addition when running in Preset mode for use with certain admixtures. This is discussed in
Chapter 5 in the section on Admix control.
The Pre-wet Water parameter sets the quantity of water that should be dosed into the mixer
during the pre-wet phase of the mix cycle.
The Pre-wet Water Limit parameter sets the maximum amount of water that will be added,
when the system is running with the pre-wet water in AUTO Mode, before the system will alarm.
The Main Water parameter sets the quantity of water that is added to the mix during the main
water addition phase of the mix cycle when running in preset mode.
If the main water addition phase is being run in CALC Mode and if the calculated water addition
quantity is larger than the Main Water Limit , the system will trigger an alarm. If the main water
addition phase is being run in AUTO Mode and the amount of water dosed reaches the Main
Water Limit
then the system will stop adding water and trigger an alarm
The Main Water Trim parameter adjusts the target of the recipe so that it can be made
temporarily wetter or drier for special mixes.
