SUPPORT PROCEDURE UNIT 2 APPENDIX NO:2-OSP-27.6 Rev: 0 R DIESEL GENERATOR OPERATION Page 4 of 36 1.0 PURPOSE 1.I This procedure establishes requirements for operation of the Unit 2 Appendix R Diesel Generator.

2.0 PRECAUTIONS AND LIMITATIONS 2.1 TRO 3.8.B applies in Modes 1,2, 3 and 4.

2.2 The Appendix R Diesel Generator maximum continuous load is 2045 kW. During an emergency, maximum generator load is 2435 kW.

2.3 Do NOT operate the engine less than 750 KW for long periods of time. Idling for a prolonged period of time (more than 30 minutes) can damage an engine.

Running with engine coolant temperature too low (below 140°F) will dilute crank case oil with raw fuel.

2.4 Crankcase oil level should only be checked using the lube oil reservoir gauge glass when the engine is running. Removing the engine oil fill cap or dipstick can allow hot oil to splash out.

2.5 Pushing the Emergency Stop button OR placing the O/Manual/Auto switch to the 0 position will cause an immediate engine shutdown (bypassing the cooldown at idle). This hot shutdown should be avoided, if possible, to prolong reliability of engine.

SUPPORT PROCEDURE UNIT 2 APPENDIX NO:2-OSP-27.6 Rev: 0 R DIESEL GENERATOR OPERATION Page 5 of 36 3.0 PREREQUISITES 3.1 Lube Oil Supply Reservoir gauge glass level indicates between 3/4 and FULL.

3.2 The following Appendix R Diesel Generator Fuel Day Tank Indications are extinguished:

Tank Rupture System Fail Critical High High Fuel Low Fuel Pump 2 Fail Pump 1 Fail 3.3 The Appendix R Diesel Generator Fuel Day Tank Level Gauge indicates between 7/8 and FULL.

NOTE When the system heats up and the coolant expands, the surge tanks should indicate between 2/3 and 314 full. This reserves 114 to 1/3 of the tank volume to accommodate system surges.

3.4 The following coolant surge tank levels are within range:

SUPPORT PROCEDURE UNIT 2 APPENDIX NO 2-OSP-276 R DIESEL GENERATOR OPERATION Page 28 of 36 ATTACHMENT 2 WARNING AND SHUTDOWN FAULT CODES (Page 1 of 4)

FlCURE 3-3 G R A P W A L DISPL&Y AH0 MEW SELECTION BUTTONS NOTE Fault codeslmessages will be displayed in the Description Line of the graphical display. (Refer to Figure 3-3 above)

The fault codes have been divided into four categories to help determine what corrective action to take for safe operation of the generator set. Use this Attachment to find the category (CTG) and fault description for all codes. Gaps in the code numbers are for codes that do NOT apply to this genset.

Category A Fault Codes: Pertain to engine or alternator shutdown faults that require immediate repair by qualified service personnel (generator set non-operational).

Control prevents the generator set from being restarted.

Category B Fault Codes: Consist of faults that can affect genset performance or cause engine, alternator, or connected equipment damage. Operate only when generator set is powering critical loads and c a n w be shut down. Requires repair by qualified service personnel.

Category C Fault Codes: Consist of faults that do NOT affect generator set performance but require qualified service personnel to repair. These codes indicate a defective harness or wiring problem.

These codes can also indicate a defective engine sensor, leaving no engine protectior (Engine damage can occur without detection). Continued operation may void generator set warranty if damage occurs that relates to fault condition.

Category D Fault Codes: Consist of faults that are repairable by site personnel.

Service will be required by qualified service personnel if site personnel c a n u resolve the problem after taking the corrective actions suggested in Attachment 3.

Category E Fault Codes: Indicates non-critical operational status of generator set, external faults, or customer fault inputs. May require repair by qualified service personnel
