Woodward V45TV-2007-MURXM-X-S-X 9907-1666 Industrial Turbine Actuator

The MicroNet Remote Real Time Network (RTN) module is designed to be located in an expansion rack.

The module’s primary function is to gather data from local I/O modules and communicate this data to the

main rack CPUs while providing redundant failover control of the rack in which it is located.

The Remote RTN module contains a MPC5200 processor, 128 Mbyte DDR RAM, 64 MB of flash

memory, a Real Time clock, and various communication peripherals. These peripherals include (3) Real

Time Network ports and (1) service port. This module includes an FPGA to provide VMEbus master/slave

capability, health monitoring, and failover functions necessary for redundant systems.

The 5 V and 5 V Precharge busses are not for external use.

The 24 V bus is accessible from the motherboard for

external use (protected by 5 A fuses on the source and return lines).

When redundant power supplies are running, current sharing circuitry balances the load to reduce heat

and improve the reliability of the power supplies.

In the event that on supply needs to be replaced, the recommended method for changing

Power Modules is with the power off (to the module being removed and the module being inserted).

The system will tolerate this “cold swap” method without failure.

Each main power supply has four LEDs to indicate power supply health (OK, Input Fault,

Overtemperature, and Power Supply Fault).

See MicroNet Plus Power Supply Troubleshooting (Section 5.5) for a description of the LED indications.

Input power connections are made to the power supply through a plug/header assembly on the front of

the power supply.
