6.35 Relay (1 - 8) Output Menus – Target PPM Feed Type
This page is used to set the flow volume to trigger feed, PPM set point, etc. Which units of
measure appear depends upon how the flow meter input assigned to the relay is configured. If you
make changes to the Input Assignment, you will need to click on the “Submit” button in order to
see all the correct units.
You may also change the Relay Control Mode here. If you do, you will have to reselect the Input
Assignment as well.
This section assumes that the Relay Control Mode is set to Target PPM Feed. Other control mode
types are described in other sections of the manual.
Relay Control Mode
Click on the arrow of the pull down menu and select the way that you want to control the relay.
See Section 6.2 for details on each control mode.
System Conductivity Input Assignment
Click on the arrow of the pull down menu and select the conductivity input that will be used to
control the relay.
Makeup Conductivity Input Assignment
Click on the arrow of the pull down menu and select the conductivity input that will be used to
control the relay. If Not Used is submitted, a field will appear for entering the makeup
conductivity manually.
Assign Makeup Meter (1-3)
Click on the arrow of the pull down menu and select the flowmeter inputs that will be used to
control the relay. If only one flowmeter will control the relay, but more than one input is available,
set them to Not Used. See Section 6.2 for details.
Accumulated Volume
This displays the volume of flow that has accumulated so far towards triggering the next feed
event. This is not the total flow, as seen in the System Summary page. This total will reset itself
once the feed has occurred. You can manually reset this total using the “Reset Total” button to the
right.
System Conductivity
This field displays the current system conductivity reading.
Makeup Conductivity
This field displays the current makeup conductivity reading.
Cycles
This field displays the current calculated cycles of concentration.
