5.2A1 STATUS 5.2.1 GENERATOR STATUS
PATH: ACTUAL VALUES Ö A1 STATUS Ö GENERATOR STATUS
These messages describe the status of the generator at any given point in time. If the generator has been tripped, is still
offline, and the 489 has not yet been reset, the GENERATOR STATUS will be "Tripped". The GENERATOR THERMAL CAPACITY
USED value reflects an integrated value of both the stator and rotor thermal capacity used. The values for ESTIMATED TRIP
TIME ON OVERLOAD will appear whenever the 489 thermal model picks up on the overload curve.
