Introduction
Do not perform any procedure in this Special Instruction until you read this information and you understand this information.This Special Instruction provides the following information for G3600 Engines:
Requirements for the electrical system
References for electrical schematics
Required electronic service tools
Components of the main terminal box
Information about the optional control panel
Connecting the optional control panel or a Programmable Logic Controller (PLC) to the Electronic Control Module (ECM)
Wiring connections and the corresponding functions that are available to the customer
Initial start-up procedureBefore the initial start-up, an engineer that is certified by Caterpillar must perform the engine commissioning at the site.ReferenceInformation from the following sources will be needed for this Special Instruction:
Complete analysis of the fuel
Caterpillar Software Program, LEKQ6378, "Methane Number Program"
The Data Sheet on the engine performance from the engine Technical Marketing Information (TMI)
Operation and Maintenance Manual, SEBU7563
Systems Operation/Testing and Adjusting, RENR5908
Troubleshooting, RENR5910Requirements for the Electrical System
All of the wiring must conform to national electrical codes, to state electrical codes, and to local electrical codes.When you route the wiring, avoid acute bends and sharp edges. To protect the wiring harnesses, route the harnesses through metal conduit. Use rigid conduit or use flexible conduit. A liquid tight conduit is recommended. Use proper support and alignment in order to avoid strain on the conduit.The customer +24 VDC circuit must provide a minimum of 20 A. The return must absorb a minimum of 20 A. The voltage drop must be no more than 1 VDC at the maximum current draw with a maximum of 150 mV AC ripple voltage.Electrical Schematics
Table 1 lists the detailed wiring diagrams for the G3600 Engines.
