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 2.2 2.3 2.4 2.5 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 2435 kW. 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. 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.

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.

(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 canw 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 canu 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 SUPPORT PROCEDURE - UNIT 2 APPENDIX R DIESEL GENERATOR OPERATION ATTACHMENT 2 WARNING AND SHUTDOWN FAULT CODES (Paae 2 of 4) NO: 2-OSP-27.6 Rev: 0 Page 29 of 36 .- I CTG 1 CODE/ LAMP~ DISPLAYED MESSAGE I A A B 11 1 Shtdn Internal ECM error 11 2 11 3 Wrno Actuator sensor fault Shtdn Actuator NOT responding I A I 115 I Shtdnl No speed signal I A A - 116 117 Shtdn I Time press sensor high Shtdn 1 Time press sensor low B B C 118 Wrng Pump press sensor high 119 Wrng Pump press sensor low 121 Wrng No engine speed signal D I 197 I Wrng I Coolant level warning c I 212 I Wrno I oil temoerature sensor B 343 Wrng Internal ECM error C I 222 I WrngIAirpressuresensor A I 228 1 Shtdn I Low coolant oressure B B C C B C I C I 231 1 WrnaICoolant pressuresensor I 122 Wrng Manifold air press sensor 123 Wrng Manifold air press sensor 135 Wrng Oil pressure sensor 141 Wrng Oil pressure sensor 143 Wrng Low oil pressure 144 Wrna Coolant temperature sensor A I 234 I Shtdn I Overspeed 1 A A A D I 235 I ShtdnI Coolant level alarm A I 236 I ShtdnI Position sensor 397 Wrng Fueling actuator #2 398 Wrng Fueling actuator #2 399 Wrna Fuelina actuator #2 C 1 263 I Wrng I Fuel temperature sensor C I 265 I Wrna I Fuel temoerature sensor D I A I 266 I Shtdnl Fuel temperature I 441 Wrng I Low battery voltage 1 D I 326 I Wrna I Oil level warning I D B B 442 Wrng High battery voltage 449 Wrng High fuel supply pressure 451 Wrno Fuel rail oressure sensor I 1 A I 378 I Wrna 1 Fueling actuator

If engine can be stopped follow 253 procedure.

Indicates that an engine hot shut down has occurred (cooldown timers were bypassed). This condition will occur when the engine coolant temperature is above the normal operating level and the operator presses the Emergency Switch or moves the OlManuallAuto switch to the 0 (Off) position. This type of shutdown should be avoided. Can cause possible loss of performance and engine damage.

Indicates that the engine oil level has exceeded the alarm trip point for high oil level. Check oil level. Drain oil to operating level. When anyone of these customer defined inputs is detected by the control, the corresponding fault message is displayed.

The nature of the fault is an optional customer selection. These fault functions can be programmed to initiate a shutdown or warning as indicated by the Warning or Shutdown lamp. Note: Customer fault messages are editable.

The message displayed for the code shown (131 1 through 1318) is determined by the customer.

Status - indicates that the "Fault Bypass" mode is enabled. This mode is primarily used by service personnel for troubleshooting purposes.

In this mode the generator set ignores the majority of system shutdown faults. Indicates that the control can NOT power down due to some unknown condition. Possible drain on battery. Contact an authorized service center for service. Indicates local or remote Emergency Stop. Emergency Stop shutdown status can be reset only at the local control panel. To reset the locallremote Emergency Stop button: Pull the button out. Move the O/Manual/Auto switch to 0 (off). Press the front panel Fault Acknowledge button. Select Manual or Auto, as required.
