Woodward 8200-510 DVP Digital Valve Positioner

If the microcontroller determines that the EEPROM is not responding correctly, a

trip occurs. The trip cause is annunciated as a hardware fault. If this type of fault

occurs, reset the unit. If the fault continues to occur, replace the unit and return it for repair.

If the microcontroller determines that the data in EEPROM has been corrupted,

the display shows "eeprom data lost". If this type of fault occurs, reset the unit. If

the fault continues to occur, replace the unit and return it for repair.

The microcontroller monitors an interlock signal which indicates that the internal

hardware cables are connected correctly. If this signal indicates a missing

interlock, a trip occurs. The cause of the trip is annunciated as an interlock fault.

If this fault occurs, check all cable connections.

If a monitor circuit determines that the microcontroller is not functioning, a trip

occurs. The CPU FAIL LED turns on. If this fault occurs, replace the unit and

return it for repair.

The TMR5200 Module is designed for 3-2-0 operation. A TMR system cannot operate with a single CPU.

This module was designed and rated for –40 to +85 °C operation in the industrial marketplace.

RTN Port

In a TMR5200 based system, each Kernel CPU provides Real Time Network (RTN) capability for

expanding to other racks using Ethernet port 4 (RJ45). This RTN port communicates between the main

chassis CPU's and any Remote RTN modules located in an expansion chassis. The GAP software

application defines the expansion racks, their I/O modules, and the use of the RTN port.
