Source 1, 2 or 3 Conductivity Range
(only appears if Feed Mode is one of the Multiple Sources types)
Type in the text box the range conductivity (or ppm) values that the controller will use to identify
the makeup water source. For example, if the water from this source is typically 275 µS/cm, set the
range at 200 to 350 µS/cm. Source 1 must be the lowest conductivity range, Source 2 the next
highest, and Source 3 the highest conductivity. The controller automatically enters the
conductivity value of the next range to prevent overlapping ranges, or gaps between the ranges.
Output Time Limit
Type in the text box the maximum amount of time that the feed pump can be continuously running
before the controller shuts off the pump and activates an Output Time Limit alarm. This is
intended to prevent the pump from emptying an entire drum of chemical because of a problem
elsewhere in the system.
Note that the feed pump will not run again until someone resets the timer! The time limit should be
set at approximately twice the normal worst case on time.
Feed Output Mode
Click on the radio buttons to manually control the feed relay. The normal selection will be Auto,
where the controller uses the various set points to open and close the relay. You can force the relay
open (pump off) regardless of the set points by selecting Off, or force the relay closed (pump on)
regardless of the set points by selecting Hand.
If you select Off, the pump will not run again until either Hand or Auto is selected! If you select
Hand, the pump will run until either Auto or Off is selected, or until the Hand Time Limit
(programmed in the next menu) expires.
The Off mode is handy to prevent the pump from running while you are changing set points. The
Hand mode is handy to be able to test the pump, wiring, etc without needing to change set points.
Hand Time Limit
Type in the text box the maximum number of minutes that the feed output can be activated in the
Hand mode. Any value between 0 and 1440 is acceptable. A value of 0 means the output can be
left on indefinitely.
Click on the “Submit” button to save the changes.
Event Log
Click on the link to view the event log. The event log contains the date and time of each relay
activation and deactivation. The data will be a 1 if the relay is closed and a 0 if the relay is open.
The log also shows the state of the flow switch, with a 1 denoting flow, and a 0 denoting no flow.
A window will open to ask if you would like to open the file or save it to disc. Select the method
you would like to use. The file is a .csv (comma separated variable) file that will open in a
spreadsheet such as Excel.
