For each input that you wish to use, click the “Config Point” button to the right of the input.
8.7.4
The input configuration requires several options. The input mode will control how the input
functions. This includes measuring voltage, current, resistance, pulse, or runtime. Use the
dropdown menu to select the mode that is appropriate for your sensor. The input configuration
must be completed for each input that is in use.
Sensor Name: change this to describe the input. This can be anything you wish, such as
“Indoor Temperature”
Input Mode: Select from one of the following: Voltage 0-10v, Current 4-20mA, Resistance, Pulse, Pulse-
KYZ, status or Unconfigured.
Sensor Make and Model: This entry is a space for the model number of the sensor. It is only used
for reference.
Sensor Minimum Range: All Analog Sensors have min/max range values. For example, a temp sensor
may have a range of 50 to 95 degrees F. Enter the low range number here.
Sensor Maximum Range: Enter the high range value of the analog sensor here.
Pulse Multiplier: For pulse mode inputs, this option specifies the multiplier for the input.
Curve Scaling: Some sensors such as thermistors have a non-linear output. This option allows a
lookup table to be specified to convert from the input reading to an engineering unit data output. Several
conversion tables (Curve Scale Templates) are provided with the DAS. For more information refer to the
Curve Scale Documentation supplement provided on the leviton.com website.
Pulse Rate: For most units, this feature is an automatic rate field. For KWH points, the rate is KW.
Engineering Units: Enter the units of measure. ie, Degrees F, %RH, etc.

After saving the sensor profile, the device configuration page will be displayed again. The
input values should now be scaled correctly and the names will be updated to your new
configuration. You may wish to set any alarm thresholds required, or check the “console” check
box for any data points that should be displayed on the LCD console.
