How are alarms processed? | Barnett Engineering ARU CV2 guide

Operations Overview

1-2

Analog inputs convert the voltage level to a digital value and perform a comparison against the programmed low and high setpoints. An alarm is present when the measured value is above or below the setpoint. Alarm messages are spoken using the stored phrase with either “High” or Low” appended depending on which setpoint has been exceeded. The actual reading, including decimal place notation and engineering units, is spoken when the Cv2 is interrogated.

The latching alarm function is also available for analog inputs.
