COMMUNICATIONS

Are the LAN switches powered and operable?

Are the Ethernet (or Serial) cables all securely connected at both ends?

Are the IP addresses on the same network domain (within subnet mask)?

Are any IP addresses duplicated? (LAN will prevent second one from joining)

Is the 5009FT configured correctly for desired port/protocol/slave #?

Are there status LEDs that can be checked for activity (on Ethernet)?
INPUT SIGNALS

Are all input signals properly scaled?

Are the inputs free of electrical noise and properly shielded?

Is the wiring correct?

Have all field input signals to the control been verified?

Is the polarity of the signals correct?
OUTPUT SIGNALS

Are the outputs calibrated?

Have the actuator drivers been calibrated to the stroke of the turbine valves?

Are the output signals free of noise and properly shielded?

Is the wiring correct?
TRANSDUCERS

Is the transducer calibrated for the proper range?

Has it been tested by simulating its input and measuring its output signal?

Does the transducer have power?

Are the sensing lines feeding the transducer clear of obstructions?
MAGNETIC PICKUPS AND OTHER SPEED SENSING DEVICES

Is the wiring between the speed sensing pickup and the control correct?

Are there any grounding problems or worn shields?

Is the signal sufficient (at least 1.5 Vrms)?

Is the signal a clean sine wave or square wave with no spikes or distortions?

Is the MPU head clean and free of oil or metallic particles?

Is the MPU head free of any nicks or chips?

Is the MPU or proximity probe correctly aligned with the gear?

Is the speed sensing probe adjusted to the correct gap?

Is the speed sensing probe head the correct size for the toothed wheel it is being used with?

Are the proper jumpers installed on the FTM?
INPUT VOLTAGE/POWER SUPPLIES

Is the input power within the range of the control’s power supply input?

Is the input power free of switching noise or transient spikes?

Is the power circuit dedicated to the governor only?

Are the control’s supplies indicating that they are OK?

Are the control’s supplies outputting the correct voltage?
ELECTRICAL CONNECTIONS

Are all electrical connections tight and clean?

Are all signal wires shielded?

Are shields continuous from the device to the control?

Are the shields terminated according to Woodward specifications?

Are there low voltage signal wires running in the same wiring trays as high voltage wiring?

Are the governor’s signal common or grounds not tied to any other devices?

Have the signals been checked for electrical noise?
VOLTAGE REGULATOR

Is the voltage regulator working properly?
