PRECAUTIONS AND LIMITATIONS 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 __ IF this is an engine start supplying Unit 2 Appendix R Loads THEN GO TO Step 4.3, Engine Start Supplying Unit 2 Appendix R Loads. All applicable prerequisites are included in that section. - IF this is an engine start during a Loss of all AC Power THEN GOTO Step 4.5, Engine Start (Loss Of AC Power/ SBO). All applicable prerequisites are included in that section.

IF this is an engine start supplying Unit 3 Appendix R Loads THEN GOTO Step, x7, Engine Start (Supply Unit 3 SBO / ASS Loads. All applicable prerequisites are included in that section.

TRO 3.8.B applies in Modes 1, 2, 3 and 4, The Appendix R Diesel Generator maximum continuous load is 2045 kW. During an emergency, maximum generator load is 2700 kW for 25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />s/yr.

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 or running with engine coolant temperature too low, below 140°F will dilute crank case oil with raw fuel. Whenever the Appendix R Diesel Generator is running log readings SHALL be established.

Log readings should be taken once an hour. Crankcase oil level should only be checked at the lube oil reservoir gage glass when the engine is running. Removing the engine oil fill cap or dipstick can allow hot oil to splash out. Pushing the Emergency Stop button placing the O/Manual/Auto switch to the 0 position will cause an immediate engine shutdown (bypassing the cool-down at idle). This hot shutdown should be avoided, if possible, to prolong reliability of engine.

(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 cannot 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 protection. (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 cannot 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 wrsonnel.
