Average and Calibration Alarms
Although AirVision and the 8872 component contains an alarm checking system, these
programs are used primarily to send e-mail notifications. In some cases, it may be necessary
to activate a physical relay or switch a Modbus digital point based on a calibration result.
For these actions, the Model 8872 supports the same local logger alarm programs as the
Model 8816 / 8832 data loggers.
Logger Average Alarms
Logger Average Alarms are set in the Logger Channels screen, using
Add > Average Alarm
.
In the same manner as the AirVision/ 8872 alarms, the user designates the parameter(s) to be
observed, the average interval, the triggering flag(s), and potentially a list of flags that might
inhibit the alarm condition (e.g., maintenance, calibration). The only addition is that the user
can set the
Output Lines During Alarm
(similar to setting relay outputs for a calibration).
These relays will be turned on during the alarm condition, and remain set until the alarm
condition goes away.
