Proportional Dosing
Used to configure proportional Parts Per Million dosing to a system. This method
of proportional dosing is based off an input signal the pump is receiving from an
external flow meter. The flow meter must have a high speed pulse output >10Hz.
You will need to refer to flow meter instruction manual to obtain the K-factor for
the flow meter.
Default settings:
12.5% dose solution concentration
1.25 dose solution Specific Gravity
5.0 K-factor (Pulses Per Liter),
see flow meter instruction manual
1.0 Parts Per Million to dose
Press MODE button until
Proportional Dosing
is displayed in the top line of the
display.
To configure the pump, navigate to
Proportional Dosing
menu by using the
short-cut method described at the beginning of the section, or by pressing
MENU button, then selecting Input Setup, Input Modes, and then
Proportional
.
Press UP or DOWN arrow to scroll through 0 - 9 on selected digit.

desired digit, you can easily scroll back by continuously pressing RIGHT button.
Press ENTER to save the changes.
Continue this process until all four screens have been configured.
If you used the short-cut to enter Proportional Dosing setup, press and hold
Mode button until Run Mode screen is displayed.
If you used the Menu button to navigate to Proportional Dosing setup, you must
navigate back out of menu structure. To do this you must select <-Esc at bottom
of every screen menu until you see Run Mode screen displayed.
