Over range detector
The Over range detector provides a simple user interface to allow users to determine if any selected channels in the test have exceeded a defined Alarm min / max value.
The output is a logical channel that is updated at the user selected test engine frame rate. The output is set to Boolean true (i.e., 1) when any input channel data sample exceeds a defined Alarm max or Alarm min value in the test engine frame period; otherwise, the output is set to Boolean false (i.e., 0). The output can be fed into a one or more Digital Output channels to drive an LED indicator.
This computed channel is provided for use with analog sensor channels primarily; however, any sequential input channel or computed channel can be selected as long the one or both of the Alarm min / max parameter values are defined.
When a channel trips an alarm, a message is generated in the system Log file that starts with "Over range" to simplify searching the Log file for the messages. Only one Alarm max exceedance and one Alarm min exceedance message will be generated for each channel over the duration of a test run. This allows the user to determine which channel(s) have tripped an alarm limit, while preventing the Log file from becoming saturated with redundant error messages.
Select the maximum number and minimum timing for notifications sent for this computed channel in Test configuration > Setup. See Test setup > Over range detection notifications for more information.
- Input channels: Select the desired set of input channels. The input channels can have different sample rates. There is no limit on the number of input channels.
- Enable notifications: Select the checkbox so notifications (through email or the HBM Push application) may be sent for the Over range detector Computed channel. See Notifications for configuring email and HBM Push notifications to be sent from the system.
