EVM and Triggering Settings
EVM Series User Manual
2. To set the Triggering for Digital Output or Analog Output, follow the steps below:
Click in the Enabled box to turn on Trigger digital/analog output.
For the Logic level, click the arrow to select a level (for digital output only).
For the parameter, select one of the sensors (Note: For air velocity, verify the sensor is
attached to the EVM and selected in the General panel of DMS.)
For the threshold, type in a value for the selected parameter or use the to select.
3. To set the triggering setup, click on or save and send to the EVM (for more details see
“Saving and sending configurations”).
Figure 6-14: EVM Triggering setup
Enables the digital output on the device when checked per the mode, parameter, and
threshold settings. NOTE: Only one of these parameters (Digital Output, Analog
Output, or Air Velocity) can be enabled at one time.
Enables the analog output on the device when checked. The analog output will vary
between 0-5 volts based upon the minimum and maximum levels for the particular
sensor.
Logic level (Also
called “Mode” on
the EVM)
The type of signal that will be triggered when the parameter and threshold are
satisfied. It may either be active high, active low, active high pulse, or active low pulse.
(Reference Table 3-3 for detailed information.)
The sensor that is to trigger the digital/analog output.
The threshold at which the sensor will be triggered for the given parameter.
Enables the Air Velocity Input when checked. NOTE: This is mutually exclusive with
the digital out meaning that only one or the other can be enabled at any given time.
Sets the units in which the wind speed will be measured, either meters per second or
feet per minute.
