Status
Possible status messages are; Normal (everything is OK)
If the type of water meter is “4-20 mA”; Sensor Error (the sensor signal is not valid), Over Range
(between 20 and 21 mA), Under Range (between 3.9 and 4.0 mA), or Circuit Board Failure. See
section 8.1 for a complete description of error messages.
Units
Click on the radio button to select volume in units of Gallons or Liters. If you change the units in
this screen, changes will not occur on the page until the “Submit” button is pressed.
Volume per Contact (appears only if the Contact radio button is selected)
Type the volume of water that needs to flow through the water meter before the meter sends a
contact into the text box. The controller uses this information to update the totalizer.
K Factor (appears only if the Paddlewheel radio button is selected)
Type the K factor (number of pulses per unit volume) of your water meter into the text box.
Consult the documentation for the water meter for information on what the K factor will be for
your particular pipe size and installation. The K factor allows the controller to translate pulses
from the meter into gallons or liters. Any value between 0.001 and 20,000 is acceptable.
Flow rate at 4 mA (appears only if the 4-20 mA radio button is selected)
Type the flow rate at which the water meter will send a 4 mA signal into the text box. This will
generally be at 0 gallons or liters/minute.
Flow rate at 20 mA (appears only if the 4-20 mA radio button is selected)
Type the flow rate at which the water meter will send a 20 mA signal into the text box. This will
generally be at the maximum rated flow rate of the meter.
Bleed Water Meter
If the use of a Bleed water meter has been selected in the Start Up menu, a set of menus that
duplicate those described above for the Makeup water meter will be available for the Bleed water
meter.

6.11 Flow Switch Input Menu
Enabled/Disabled
Click on the radio button that describes what you want to do.
Enabled means that the if the flow of sample past the flow switch stops, then the controller will
stop control based on the sensor signals. This is the normal method of operation.
Disabled can be used to ignore the flow switch and control regardless of whether the sample is
stagnant or not. This is not recommended unless the flow switch is defective and you know that
flow is not going to stop before you have a chance to repair the flow switch.
Interlock Status
Click on the radio buttons to define which control relays will be shut off if the sample flow stops.
Any output that is turned on based upon a sensor that is installed in the sample line should be
interlocked!
