Configuration, Fast Meter, and Fast Operate Commands D-15
SEL-300G Instruction Manual Date Code 20001212
A5B9 Fast Meter Status Acknowledge Message
In response to the A5B9 request, the relay clears the Fast Meter (message A5D1) Status Byte.
The SEL-300G Status Byte contains one active bit, STSET (bit 4). The bit is set on power up
and on settings changes. If the STSET bit is set, the external device should request the A5C1,
A5C2, and A5C3 messages. The external device can then determine if the scale factors or line
configuration parameters have been modified.
