FUNCTIONAL DESCRIPTION:

IS220PEFVH1A is an Electric Fuel Valve Gateway Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Electric Fuel Valve Gateway (PEFV) is an Ethernet gateway between the Mark VIe I/O Ethernet network and an electric fuel valve interface module. The module communicates through the Ethernet Global Data (EGD). The fuel valve interface module is called a Digital Valve Positioner (DVP). It is made by Woodward Controls. The PEFV contains a processor board common to all Mark VIe I/O packs. One of the dual RJ45 Ethernet connectors connects to the I/O Ethernet network. The other RJ45 Ethernet connector connects directly to the DVP. A 3-pin connector supplies power to the pack.

COMPATIBILITY:

The Electric Fuel Valve Terminal board (TEFVH1A), in this configuration, is used to mount the PEFV only. The connections on the board are for electronic ID only. It uses no other connections. Visual diagnostics are provided through indicator LEDs on the PEFV. An infrared port provides local diagnostic serial communication. Control mode refers to the number of I/O packs used in a signal path:

• Simplex uses one I/O pack with one network connection on each.
• Dual uses two I/O packs with one network connection on each.
• TMR uses three I/O packs with one network connection on each.

INSTALLATION:

• Directly plug three PEFVs, for triple modular redundancy (TMR), into the terminal board connectors.
• Mechanically secure the packs using the threaded inserts adjacent to the Ethernet ports. The inserts connect to a mounting bracket specific to the terminal board type. The bracket should be adjusted so there is no right angle force applied to the DC-37 pin connector between the pack and the terminal board. This adjustment is required once during the life of the product.
• Plug one Ethernet cable into the I/O Ethernet network. Connect the other Ethernet cable to the corresponding network connector on the Woodward DVP.
• The pack will operate with connections made to either port. The pack must reboot if the connections are modified. Standard practice is to connect ENET1 to the network associated with the I/O Ethernet network.
• Power is applied to the connector on the side of the pack. It is not necessary to insert the connector with the power removed from the cable. PEFV has inherent soft-start capability that controls current inrush on power application.

OPERATION:

The processor board connects to an acquisition board specific to the I/O pack function. Upon application of input power, the soft-start circuit ramps up the voltage available on the processor board. The local power supplies are sequenced, and the processor reset is removed. The processor completes self-test routines and then loads application code specific to the I/O pack type from flash memory. The application code reads board ID information to match the application code, acquisition board, and terminal board correctly. With a good match, the processor attempts to establish Ethernet communications, starting with the request of a network address. The address request uses the industry standard dynamic host configuration protocol (DHCP) and the unique identification read from the terminal board. After Ethernet initialization, the processor programs the on-board logic, run the application, and enables the acquisition board to begin operation.

FREQUENTLY ASKED QUESTIONS:

What is an Electric Fuel Valve Gateway?

An Electric Fuel Valve Gateway is a device that manages and controls the flow of fuel in an electronic fuel system. It acts as an interface between the fuel supply and the engine, ensuring precise fuel delivery for optimal engine performance.

How does an Electric Fuel Valve Gateway work?

The gateway receives electronic signals from the engine control unit (ECU) to regulate the opening and closing of the fuel valve. This ensures that the correct amount of fuel is delivered to the engine based on its operational needs.
