6.24 Relay (1 - 8) Output Menus – Flow Based Feed Type
This page is used to set the flow volume to trigger feed, feed time, 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 Flow Based 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.
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. If more than one flowmeter is used, they should all have the same units of
measure, and the controller will use the units of measure of Makeup Meter 1. See Section 6.2 for
details.
Status
This displays the current status of the Relay Output, either “Off” or “On”, and if on, the time it has
been on and any alarm conditions. Possible status messages are Off, Off/manual, On/Time
counting down, Off/Time counting down or On/Time counting down/Hand (for manual relay
activation). Possible error messages are Timeout, Interlock, or Pump Failure. See section 8.1 for
a complete description of error messages.
