ALARMS panel
Setting of the alarm thresholds for each of the available quantities. The alarm is gen-
erated if the measured value falls below the lower threshold or rises above the upper
threshold. The hysteresis and the delay time of the alarm can be configured.
The amplitude of the hysteresis is in percentage (0...100%) of the difference between the
two alarm thresholds. For example, if the hysteresis is 2%, the lower threshold is 10 °C
and the upper threshold is 60 °C, the hysteresis in °C is equal to (60-10)x2/100= 1 °C.
The alarm is generated after the set delay time (or immediately if the “
no delay”
op-
tion is selected). If the alarm condition disappears before the delay time has elapsed,
the alarm is not generated.
