Woodward 9908-1666 GS50 Gas Fuel Valve Actuator with On-board Driver

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 (GAP block is

RTN).

The overspeed test function is activated when the key switch is in the

PROGRAM position and the operator presses and holds the OVSP TEST button

on the touch pad. The microcontroller switches the source of the MPU signal

from the MPU input to an on-board oscillator. The test speed is annunciated on

the LCD. If the test speed is adjusted above the trip setpoint, using the Test

Frequency potentiometer on each unit, a trip occurs. MPU loss-of-signal

checking is disabled, and the peak speed value does not change during

overspeed test. When the OVSP TEST button is released, the microcontroller

switches the source of the MPU signal back to MPU input and normal operation

is restored. Each ProTech unit must be reset to clear its trip condition.
