Power Train System and Accessory Power System components and conductors that could be involved when an EID 715 Event is activated. (1) HVAC electric compressor motor (2) Accessory Power Bus (APC to electric compressor motor) (3) Accessory Power Converter (DC down convert) (4) DC Power Bus (Power Inverter to APC) (5) Power Inverter (Generator Control 1 side, Motor control 2 side, internal DC Power Bus) (6) Water Pump Motor Control (7) Accessory Power Bus (APC to Water Pump Motor Control) (8) Motor 1 three-phase conductor assembly (Power Inverter to Motor 1 connector on electric Drive Propulsion Module) (9) Motor 2 three-phase conductor assembly (Power Inverter to Motor 2 connector on electric Drive Propulsion Module) (10) Generator three-phase conductor assembly (Generator to Power Inverter) (11) Electric Drive Propulsion Module (Electric Drive Motor 1, Electric Drive Motor 2) (12) Electric water Pump Motor (13) Electric Water Pump three-phase conductor assembly (Water Pump Motor Control to Electric Water Pump) (14) Generator (three-phase stator windings)The E715 Ground Fault Event is a Level 3 Ground Fault Event. This Event is a general ground fault warning. The E715 is activated when the detection system cannot determine which section of the electrical power train system the ground fault is occurring in. The ground fault could be occurring in the DC section of the system. The ground fault could be occurring in the AC section of the system.When the E715 Event is activated by the Implement ECM, an immediate safe machine shutdown must take place to avoid possible damage to system components.For purposes of identifying different parts of the Power Train Electric Drive System and the Accessory Power System where the APC can detect ground fault leakage, the Alternating Current (AC) voltage system and the Direct Current (DC) voltage system will be referenced.The AC voltage system includes the following system components:
(14) The internal Generator three-phase AC stator windings and connectors.
(10) The external Generator three-phase AC conductors and connectors between the Generator and the Power Inverter.
(5) The Power Inverter internal three-phase AC connections, components, and circuitry that make up the Control 1 side of the Power Inverter. This side of the inverter is where the three-phase AC Generator output is converted to DC Power.
(5) The Power Inverter internal three-phase AC connections, components, and circuitry that make up the Control 2 side of the Power Inverter. The inverter control 2 side is where the DC Power Bus voltage is inverted to the three-phase PWM output voltage that is sent to the two electric drive motors.
(8, 9) The two sets of external three-phase AC conductors and connectors. The connectors are connected between the Power Inverter and the two electric drive motor connections on the Electric Drive Propulsion Module.
(11) The internal drive motor three-phase AC stator windings and connectors for both of the electric drive motors. The motors are inside of the Electric Drive Propulsion Module.
(13) The external three-phase AC power conductors and connections that are between the Water Pump Motor Control and the Electric Water Pump Motor.
(12) The
