h: value of the hysteresis. A hys-
teresis value that is equal to 0
means that the device reacts as
soon as a limit is reached.
A: low error limit (
Error low
)
B: low warning limit (
Warning low
)
C: high warning limit (
Warning
high
)
D: high error limit (
Error high
)
1: normal range of the monitored

2a: lower warning range of the
monitored value
3a: lower error range of the moni-
tored value

Normal range
Green status indicator, no message
•
if the monitored value was in the LOWER
warning range and the LOW WARNING value +
the HYSTERESIS value is reached.
•
if the monitored value was in the UPPER
WARNING range and the HIGH WARNING
value minus the HYSTERESIS value is reached.
Error range
Red status indicator, error message
•
if the monitored value was in the LOWER
warning range and the LOW ERROR value is
reached.
•
if the monitored value was in the UPPER
warning range and the HIGH ERROR value is
reached.
Warning range Yellow status indicator, warning
message
•
if the monitored value was in the LOWER error
range and the LOW ERROR value + the HYS-
TERESIS value is reached.
•
if the monitored value was in the normal range
and the HIGH WARNING value is reached.
•
if the monitored value was in the UPPER error
range and the HIGH ERROR value minus the
HYSTERESIS value is reached.
•
if the monitored value was in the normal range
and the LOW WARNING value is reached.
