The 825-P allows mapping of protection trip elements to the trip output.
Table 42 shows the method of mapping elements using Relay Word bits
associated with elements. Select 1 for each element you want to map using the
TRIPA through TRIPD settings. The relay will OR them together to drive the
Trip output. A logical “OR” describes when any one assigned element asserts,
the Trip relay will operate.
