1. YOU MUST LOOK AT THE 3-LINE DIAGRAMS TO FULLY UNDERSTAND THE RELAYING.

2. This plant is provided with LOCAL MANUAL, LOCAL AUTOMATIC, and REMOTE

AUTOMATIC controls for starting and stopping each unit.

3. Governor oil pumps, transformer cooling equipment and air compressor systems will be left in continuous service except for prolonged shutdown periods.

All other unit auxiliaries are taken out of service automatically when unit is shutdown.

4. May be combined by switching potentials.
