Each operating level has its corresponding functional output signal:
•
HIWARN
•
HIALARM
•
LOWWARN
•
LOWALARM
The logical value of the functional output signals changes according to Figure 182.
The user can set the hysteresis, which determines the difference between the operating
and reset value at each operating point, in wide range for each measuring channel sep-
arately. The hysteresis is common for all operating values within one channel.

The actual value of the measured quantity is available locally and remotely. The mea-
surement is continuous for each channel separately, but the reporting of the value to the
higher levels depends on the selected reporting mode. The following basic reporting
modes are available:
•
Periodic reporting.
•
Periodic reporting with dead-band supervision in parallel.
•
Periodic reporting with dead-band supervision in series.
•
Dead-band reporting.
