TURBOCHARGER GP 7N1758 - Caterpillar

OP9 is the option for verifying that EMCP II operates correctly when a fault occurs with low oil pressure, high coolant temperature or engine overspeed. The GSC will shut down the engine during a engine overspeed fault. The GSC will shut down the engine or the GSC will sound the alarm during a low oil pressure fault. The programmed setpoint P03 determines the GSC response. The GSC will shut down the engine or the GSC will sound the alarm during a high water temperature fault. Setpoint P03 determines the GSC response. OP9 is only for verification of certain engine setpoints. OP5 is used for the actual programming of these setpoints. The setpoints that are verified by this procedure are listed below.P03 Shutdown Override For Engine Fault - This action is the GSC response to a low engine oil pressure fault. This is also the GSC response to a high coolant temperature fault. The default setting from the factory is 0.0 - engine shutdown1 - alarm only (shutdown override)P10 Engine Overspeed - P10 is the engine speed that is used by the GSC in order to declare that an engine overspeed fault exists. The setpoint for the engine overspeed for all 60 Hz applications is 1.18 times the rated speed. The range of values is from 50 to 4330 rpm. The value is set in increments of 10. The default setting from the factory is 2120 rpm.P13 Low Oil Pressure Shutdown At Rated Speed - P13 is the selected oil pressure that is used by the GSC to declare that a low oil pressure shutdown fault exists. This setpoint is active with the engine at rated speed. Also, the engine speed must have exceeded the oil step speed for nine seconds. The range of values is from 34 to 420 kPa (5 to 61 psi). The value can be raised in increments of 1. The default setting from the factory is 205 kPa (30 psi). Note: When oil pressure drops to 34 kPa (5 psi) of the P13 setpoint a low oil pressure alarm is issued by the GSC. If the generator is equipped, the optional alarm module issues an alarm also. The NFPA 99 remote annunciator will not issue an alarm. P14 Low Oil Pressure Shutdown At Idle Speed - This setpoint tells the GSC when the GSC should declare that a low oil pressure shutdown fault exists with the engine at idle speed. The engine must have been running for at least nine seconds, and the engine speed must be less than the oil step speed. The fifth character of the model number specifies this setpoint. The default setting from the factory is 70 kPa (10 psi). The value is selectable from 20 to 336 kPa (3 to 50 psi) in increments of one.Note: An oil pressure alarm is issued by the GSC when the oil pressure drops to 34 kPa (5 psi) of the P14 setpoint. When oil pressure is greater than the
