When the TrueBlend Controller is used in retrofit replacement applications, follow the
initial setup procedure below to ensure your blender will run at its optimum accuracy.
This procedure sets the default dosing rates and settling times. This set up will help the
blender control “home in” on the actual dosing rate quicker.
1
Determine the valve configuration for the particular blender.
This can be done
simply by measuring the operating mechanisms and noting the type of mechanism.
Example: Blender XYZ
Component 1 -3”x6” valve
Component 2 - 3”x6” valve
Component 3 - 2”x3” valve
Component 4 - 2”x3” valve
Component 5 - 2” i.d. feeder
Component 6 - 1” i.d. feeder
2
Select the proper dosing rates for the different valve configurations from the fol-
lowing table.
Example: Blender XYZ
Component 1 – 3” X 6” valve – 4000 g/s
Component 2 – 3” X 6” valve – 4000 g/s
Component 3 – 2” X 3” valve – 850 g/s
Component 4 – 2” X 3” valve – 850 g/s
Component 5 – 2” i.d. feeder – 40 g/s
Component 6 – 1” i.d. feeder – 8 g/s
3
Enter the default flow rates into the blender control on the dosing rate screen.
4
Select the proper default settling times for the different valve configurations
from the following table:
Example: Blender XYZ
Component 1 – 3” X 6” valve – 1.5 s
Component 2 – 3” X 6” valve – 1.5 s
Component 3 – 2” X 3” valve – 1.5s
Component 4 – 2” X 3” valve – 1.5 s
Component 5 – 2” i.d. feeder – 5 s
Component 6 – 1” i.d. feeder – 10 s
5
Enter the default settling times into the blender control on the settling times
screen.
6
Run a material calibration for each of the components.
7
Run the blender, making sure that all materials are present in sufficient quanti-
ties for correct operation.
While running, the blender control will automatically
adjust the dosing rate for optimum operation.
