Seven frequency out-of-band accumulators are available. The following settings are available for each accumulator.
• FREQ ACCUM 1 FUNCTION: This setting enables and disabled a particular frequency band.
• FREQ ACCUM 1 UPPER FREQ: This setting specifies the upper frequency value, in Hz, below which band 1 values
start to accumulate. This upper frequency value must be greater than the lower frequency value.
• FREQ ACCUM 1 LOWER FREQ: This setting specifies the lower frequency value, in Hz, above which band 1 values
start to accumulate. This lower frequency value must be less than the upper frequency value.
• FREQ ACCUM 1 TIME LIMIT: This value specifies the accumulation time, in seconds, at which the overfrequency
accumulation band exceeds the overfrequency accumulation limit and operates.
• FREQ ACCUM 1 TIME PRESET: This setting allows the user to either transfer accumulated frequency time of opera-
tion values from a previous hardware platform to a new platform, or, given that some knowledge of the operation of the
turbine is known, to start accumulation at a user-specified value.
