b. Type in the appropriate values for the dry contact sensor hardware.
c. When you have finished, click OK to add this sensor definition to the list of available Sensor
Types.
• Define the custom 4-20mA sensor
a. After you select 4-20mA and click OK, the Add Custom 4-20mA Sensor window opens.
This window features the following fields and controls:
b. Type in the appropriate values for the analog sensor hardware.
c. When you have finished, click OK to add this sensor definition to the list of available Sensor
Types.
Close-Open Switch Time (ms) The amount of time that must pass (in milliseconds) when the
dry contact sensor goes from Closed state to Open state before
the state change is reported.
Dry Contact Type Specifies whether the dry contact sensor is a normally open
(NO) or normally closed (NC) dry contact sensor.
Field Description
Sensor Type Label The label represents the name of the custom sensor definition.
For example, if you are creating a custom sensor definition for
use with temperature sensor Model 42 from MyCo, Inc., you
might want to use “MyCo Model 42 Temperature Sensor” as the
Sensor Type Label. Once defined, the Sensor Type Label
appears only in the Sensor Type Installed drop box when
specifying Sensor Pod external port settings.
Default Sensor Label This is the text that is used, by default, as a label for any new
sensors added using this custom sensor definition. This label is
used to identify each individual sensor in the Sensor Readings
pane, as well as in all interfaces and alert notifications. Once a
sensor has been added to your appliance, you can use the Sensor
Pod Settings task (see “Settings” on page 97) to modify the
labels for easier sensor-specific identification.
mA 1 / Sensor Value
and
mA 2 / Sensor Value
Use the mA 1 / Sensor Value and mA 2 / Sensor Value fields to
specify 2 reference points (between 4 and 20 mA) for the sensor
readings. Using these two points, the appliance will use linear
interpolation to determine the full range of sensor values that
correspond to the voltage readings reported by the sensor.
Minimum Sensor Value The lowest value that will be reported by the sensor.
Maximum Sensor Value The highest value that will be reported by the sensor.
Sensor Increment The numeric increments in which the sensor reading rises or
falls.
Units The unit of measurement that is used for this sensor.
