EXAMPLE:
Dual Motor Drive System: Two motors on a dual motor drive
are each protected by SR469s. The motors should be at the
same power level (kWs). Connect the analog outputs
(programmed for kWs) from both relays to one of the relays
analog inputs. Program the analog input differential feature to
monitor the two motors kWs and trip at a predetermined level.

FUNCTION:
This feature allows the relay to compare two of the analog inputs and activate alarms or trips based on the difference between them.
The difference can either be in the form of an absolute difference in units or a percentage difference. The second analog input (4 for 3-4)
is used as the reference value for percentage calculations. The logic for the comparison can also be selected as one input greater than
the other (3>4) or vice versa (4>3) or as absolute difference (3<>4).
Note that the analog inputs to be compared must be programmed prior to programming this feature. They must also be programmed
with the same units type.
