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.
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.
Custom Name
This menu allows you to call the output another name if desired. Type the new name in the text
box.
Unit Volume to Trigger Output
Type in the text box the volume of solution that needs to enter the system in order to trigger the
feed.
Output On-Time Per Unit Volume
Type in the text box the amount of time for the relay output to activate, once the previously
specified volume of solution has entered the system. Any value between 1 and 1440 minutes is
acceptable.
Reset Timeout
(only appears if the Output Time Limit below has been exceeded)
There is a button called “Reset Timeout” which is used to reset the output if it has been activated
for longer than the time limit imposed in the “Output Time Limit” menu described below.
