automatic reset (continuously resetting). When required, automotive type fuses will be utilized to <br />protect electronic equipment. Control relays and solenoid will have a direct current rating of 125 <br />percent of the maximum current for which the circuit is protected per NFPA. <br />Solid -State Control System <br />A solid-state electronics based control system will be utilized to achieve advanced operation and <br />control of the vehicle components. A fully computerized vehicle network will consist of electronic <br />modules located near their point of use to reduce harness lengths and improve reliability. The control <br />system will comply with SAE J1939-11 recommended practices. <br />The control system will operate as a master -slave system whereas the main control module instructs all <br />other system components. The system will contain patented Mission Critical software that maintains <br />critical vehicle operations in the unlikely event of a main controller error. The system will utilize a Real <br />Time Operating System (RTOS) fully compliant with OSEKNDXTM specifications providing a lower cost <br />of ownership. <br />For increased reliability and simplified use the control system modules will include the following <br />attributes: <br />• Green LED indicator light for module power <br />• Red LED indicator light for network communication stability status <br />• Control system self test at activation and continually throughout vehicle operation <br />• No moving parts due to transistor logic <br />• Software logic control for NFPA mandated safety interlocks and indicators <br />• Integrated electrical system load management without additional components <br />• Integrated electrical load sequencing system without additional components <br />• Customized control software to the vehicle's configuration <br />• Factory and field re programmable to accommodate changes to the vehicle's operating <br />parameters <br />• Complete operating and troubleshooting manuals <br />• USB connection to the main control module for advanced troubleshooting <br />To assure long life and operation in a broad range of environmental conditions, the solid-state control <br />system modules will meet the following specifications: <br />• Module circuit board will meet SAE J771 specifications <br />• Operating temperature from -40C to +70C <br />• Storage temperature from -40C to +70C <br />• Vibration to 50g <br />• IP67 rated enclosure (Totally protected against dust and also protected against the effect of <br />temporary immersion between 15 centimeters and one (1) meter) <br />• Operating voltage from eight (8) volts to 16 volts DC <br />The main controller will activate status indicators and audible alarms designed to provide warning of <br />problems before they become critical. <br />44 of 89 <br />
