ANALOG IN DIFF 1-2 COMPARISON
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.
For example, two motors on a dual motor drive are each protected a 469. The
motors should be at the same power level (kW). Connect the analog outputs
(programmed for kW) from both relays to the analog inputs of one relay. Program
the analog input differential to monitor the two motors kW and trip at a
predetermined level.
