3 Section 2 - Engine Identification Page 2-3 Fire Pump Engines Cummins complete line of fire pump engines have been approved as packaged units (engine and all accessories) by Factory Mutual Research and listed by Underwriter s Laboratories, Inc. and Underwriter s Laboratories of Canada. Because of the lengthy and expensive process to design and produce a fire pump engine that meets these requirements, no deviations are permitted without approval. These engines are to be used only for fire protection applications. Overspeed Switches Each engine is equipped with an overspeed switch which will activate the fuel pump solenoid valve and shut off the engine when the RPM exceeds a present limit. The overspeed switch senses engine speed during the start cycle and stops the starting motor cranking cycle. The overspeed switch must be adjusted to the required speed limit during the in-service inspection. Operating Speed All Cummins fire pump engines are shipped from the factory with the operating speed adjusted to the lowest approved operating speed. Final operating speed adjustment must be made at the time of the in-service inspection to obtain the required fire pump operating speed specified by the pump manufacturer. Control System The function of a fire pump controller is to start the engine. These controllers are more sophisticated than standard industrial controllers because they include special items for fire pumps. Several options are available: The automatic start controller can be used for either automatic or manual stop after the fire demand signal is removed. Pressure recorders are available to provide a permanent record of water pressure fluctuations and engine starts. Sequential starting is available for multiple-pump installations to keep all pumps from starting simultaneously. NOTE: Fire pump controllers are not supplied by Cummins Fire Power, or Cummins Engine Company, Inc.

11 Section 2 - Engine Identification Page 2-11 Fire Pump Identification The fire pump dataplate shows specific information about your engine. The engine serial number provides information for ordering parts and service needs. NOTE: The fire pump dataplate must not be changed unless approved by Cummins Fire Power. Factory Setting Tag The Factory Setting Tag is located at the pump end of the engine just above the redundant starter solenoids. Refer to Drawing 8703 (CFP39-F15) in Section 13 for location details. This tag identifies to rated operating speed at the rated horsepower. It also provides the over speed switch setpoint. Both values are set at the factory. Refer to Installation Instructions in Section 3 for procedures to verify or adjust either setpoint. FACTORY SETTING

12 Page 2-12 Section 2 Engine Identification Bosch Rotary Fuel Injection Pump Dataplate The injection pump dataplate for the Bosch VE pump is located on the side of the injection pump. The dataplate provides information for fuel pump calibration. Bosch In-line The injection pump dataplate for the Bosch in-line pump is located on the side of the injection pump. The data plate provides information for fuel pump calibration. CAV Rotary The injection pump dataplate for the Lucas DPA pump is located on the side of the injection pump. The dataplate provides information for fuel pump calibration. Stanadyne Rotary The injection pump dataplate for the Stanadyne DB4 is located on the side of the injection pump. The dataplate provides information for the fuel pump calibration.

13 Section 2 - Engine Identification Page 2-13 Denso In-line The Denso fuel injection pump dataplate contains the following information: (A) Fuel injection pump part number (B) Denso serial number (C) Cummins part number (D) Fuel injection pump bar code. The Cummins part number for the fuel pump-governor combination is located on the governor dataplate. Delphi Rotary The injection pump dataplate for the Delphi DP pump is located on the side of the injection pump. The dataplate provides information for fuel pump calibration.
