5.13.3 Analog Input Diff 1-2
PATH: SETTINGS ZV S12 ANALOG I/O ZV ANALOG INPUT DIFF 1–2
Note
This settings menu is seen only if Analog Inputs 1 and 2 are enabled. The ANALOG IN DIFF 1-
2 TRIP LEVEL
and ANALOG IN DIFF 1-2 ALARM LEVEL settings are shown units of “%” if the
ANALOG IN DIFF 1-2 COMPARISON is “%Diff” or in units defined by the ANALOG INPUT 1 UNITS
settings if
ANALOG IN DIFF 1-2 COMPARISON is “Abs Diff”.
This feature compares two analog inputs and activate alarms or trips based on their
difference, which can be an absolute difference in units or a percentage difference. The
second analog input (2 for 1-2) is used as the reference value for percentage calculations.
The comparison logic can also be selected as one input greater than the other (“1>2”) or
vice versa (“2>1”) or as absolute difference (“1<>2”). The compared analog inputs must be
programmed with the same units type prior to programming this feature.
