OP9 is the option for verifying that EMCP II operates correctly when a fault occurs for any of the following conditions:
low oil pressure
high coolant temperature
engine overspeedThe GSC will shut down the engine during an 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 is the GSC response to a low engine oil pressure fault or this is 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 engine overspeed setpoint 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 in order to declare that a low oil pressure shutdown fault exists. This setpoint is active when the engine is 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. P15 High Water Temperature Shutdown - P15 is the coolant temperature that is used by the GSC in order to declare that a high coolant temperature shutdown fault exists. The fault is declared after a 10 second delay. The range of values is from 94° to 123°C (201° to 253°F). The value can be changed in increments of 1. The default setting from the factory is 107°C (225°F).Note: When coolant temperature rises to within 6°C (11°F) of the P15 setpoint, a high water temperature alarm is issued by the GSC. If the generator is so equipped, the optional alarm module issues an alarm as well. The NFPA 99 remote annunciator will not issue an alarm.The engine setpoints cannot be verified until the following conditions
