Woodward V45TG-2007-MURXM-P-S-X 9907-2249 Industrial Turbine Actuator

All shielded cable must be twisted conductor pairs with either a foil or a braided

shield. All signal lines should be shielded to prevent picking up stray signals from

adjacent equipment. Connect the shields as shown in the plant wiring diagram

(Figure 2-1). Wire exposed beyond the shield must not exceed two inches. The

other end of the shield must be left open and insulated from any other conductor.

Do not run shielded signal wires with other wires carrying large currents. See

manual 50532. EMI Control in Electronic Governing Systems, for more information.

Installations with severe electromagnetic interference (EMI) may require shielded

cable run in conduit, double shielded wire, or other precautions. 

Each of the three ProTech units must be reset before the turbine is started. A unit

is reset by pressing the front panel RESET button or by momentarily closing the

remote reset contact (TB5-4 to TB5-5). After the power-up self-tests, each

ProTech unit begins executing its speed-sensing algorithm. If the speed does not

exceed the MPU FAIL SETPOINT speed within the MPU FAIL TIMEOUT value,

the unit trips. At this time the MPU FAIL LED turns on and remains on until the

next reset. This trip is not affected by the TRIP ON MPU FAILURE option. The

ProTech overspeed protection system will trip on an overspeed condition during start-up.
