Controller Date Format
Click on the radio button that corresponds to the desired date format. The choices are
Month/Day/Year, Day/Month/Year or Year/Month/Day.
Sensors 1-4
Use the pull-downs to select which type of sensor is connected to that input. If the input option
cards are not installed for Sensors 2-4, then the pull-down will not be available. The sensor options
are Not Used, Contacting Conductivity, Electrodeless Conductivity, pH, ORP, Chlorine, Chlorine
Dioxide and High Temp Conductivity.
Make sure that you correctly match the programmed sensor type with the actual sensor type
connected to that input!
Digital Inputs
Use the pull-downs to select the function for each of the digital inputs. Digital Inputs A-F are
standard, while Digital Inputs 1-6 are only available if the Digital Input option card has been
installed. The functions available are explained below.
Make sure that you correctly match the programmed sensor type with the actual sensor type
connected to that input!
Not Used should be selected if nothing is connected to that input.
Contacting Flow Meter should be selected if a low frequency (10 Hz maximum) contacting-head
water meter is connected to that input. These are generally reed switch sensors that give one dry
contact closure every gallon or more of volume through the meter. A sensor of this type must be
connected to Digital Input A-F or 1-4.
Paddlewheel Flow Meter should be selected if a high frequency (10 – 300 Hz) Hall Effect style
flow meter is connected to the input. The input is not compatible with flow sensors that generate
their own sine wave. A sensor of this type must be connected to Digital Input A-D or 5-6.
Counter should be selected if the contact closure from the sensor will be used to log counts and/or
to initiate a relay to activate for a given time after a given number of counts. A sensor of this type
can be connected to any Digital Input.
Interlock should be selected if the contact closure will be used to deactivate relays that are
normally being controlled by some other means. A sensor of this type can be connected to any
Digital Input.
Level Switch should be selected if the device connected is a liquid level switch. This is normally
used to send an alarm if the liquid level gets too high or low. A sensor of this type can be
connected to any Digital Input.
Feed Verification should be selected if a metering pump feed verification device is connected to
the input. These devices can count strokes of the pump’s diaphragm, totalize the flow, and send an
alarm if the WebMasterONE relay used to activate the pump is active, but the device is not
registering any flow. A sensor of this type can be connected to any Digital Input.
Generic Input should be selected if the contact closure will be used to log the current state of the
contact (open or closed). A custom message can be assigned to each state. An alarm may be sent if
the contact changes state, if desired. A sensor of this type can be connected to any Digital Input.
