10.4. ALARM CONFIGURATION (APPLIES TO AR432/434/436)
When displaying the measured values, the sensor also enables the alarm signalling with short blinking of "LED -
alarm" LEDs repeated every 1 second. The alarm characteristics and values of alarm thresholds for the measured
value define the lower and upper alarms (chapters 10.2 and 10.3). To obtain lower, upper, outside the band alarm -
set the lower alarm at the value
lower
than the upper alarm - Fig.10.4.1. Alarm in the specified band occurs when the
value of the lower alarm is
higher
than the upper alarm - Fig.10.4.2.
11. MESSAGE AND ERROR SIGNALLING
