Operation of the variable impeller disc 2.4/3
The table in the “Impeller disc” tab shows the “Input”
and “Output” columns.
Input
is an integral value (integer) in the range
between 0 and 27,648; it corresponds to
the 4-20 mA range of the potentiometer.
Output is the impeller disc diameter.
•
The fields (grey) displaying the current value are
shown on top.
•
The rows below contain fields (white) in which
the values for the control characteristic are
entered.
Determining the values
1. Demount the cover of the remote impeller disc
adjustment actuator by loosening the 4 screws.
2. Turn the handwheel on the actuator to minimum
impeller disc diameter.
3. Adjust the adjusting screw (2) until the current
value in Touch Control shows approx. 0.
4. In the top row of the input fields (white), enter
the minimum impeller disc diameter in the
“Output” column; then enter the current “Input”
value in the top row of the “Input” column.
5. Turn the handwheel on the actuator to
maximum impeller disc diameter.
6. Adjust the adjusting screw (1) until the current
value in Touch Control shows approx. 25000.
7. In the bottom row of the input fields (white),
enter the maximum impeller disc diameter in
the “Output” column; then enter the current
“Input” value in the bottom row of the “Input”
column.
8. Test setting.
Use the arrow buttons to select the minimum
impeller diameter (input value has to be 0).
Use the arrow buttons to select the maximum
impeller diameter (input value has to be 25000).
If different values are shown, repeat
steps 2 to 7.
