Hardware Replacement

The user is permitted to replace some components of the QuickTrip in turbine shutdown conditions. The

user is also permitted to replace some components of the QuickTrip during normal turbine operation

conditions. The replacement components must be Woodward recommended products. Only this

guarantees full component compatibility and functionality. All safety instructions and detailed procedures

from this manual must be followed.

Service and Replacement Parts:

• Service Manual (26842) – Consult Woodward distributor for part number

• Solenoid – On-line replaceable. Consult local Woodward distributor or service manual for part number

• Electronics module (PCBA) – On-line replaceable. Consult local Woodward distributor or service manual for part number

• Return Spring – Consult local Woodward distributor or service manual for part number

• Sight Window – On-line replaceable. Consult local Woodward distributor or service manual for part number

• Top Cover – On-Line replaceable. Consult local Woodward distributor or service manual for part number

• Bottom Cover – Consult local Woodward distributor or service manual for part number

• Interface Seals Kit(s) – Consult local Woodward distributor or service manual for part number

• Woodward Field Repair Tools Kit – Consult Woodward distributor for part number.

Manually Stroking QuickTrip (powered)

Manually Stroking Valve Procedure:

1. To manually stroke the QuickTrip valve, the actuators must be powered with 24 VDC. Make sure the

power supply is connected and operating while performing this procedure. This can be verified by

viewing the LED status through the sight window on top of the valve. One or two blue LED’s indicate

that the power supply is connected and is turned on.

2. If QuickTrip is in a run state, as indicated by a green LED as viewed through the sight glass,

QuickTrip may be manually tripped either by de-energizing the logic solver interposing relay to initiate

a trip state or by tripping the breaker to the Control In discrete input terminals on the QuickTrip

electronics module (terminals 5 and 6 of TB2).

3. If QuickTrip is in a trip state, as indicated by a red as LED viewed through the sight glass, QuickTrip

may be energized to close either by activating the logic solver interposing relay to initiate a run state

or by supplying a separate 24 VDC input to the Control In terminals on the QuickTrip electronics

module (terminals 5 and 6 of TB2).

Manually Stroking QuickTrip Using ProTechTPS (powered)

Manually stroking valve using ProTechTPS procedure:

1. If QuickTrip is in a run state, as indicated by a green LED as viewed through the sight glass,

QuickTrip may be manually tripped by de-energizing the ProTechTPS interposing relay to initiate a

trip. This may be done by using the Temporary Overspeed Setpoint Test (see ProTechTPS product

manual for more detailed instructions on this function).

2. If QuickTrip is in a trip state, as indicated by a red LED as viewed through the sight glass, QuickTrip

may be energized to close by activating the ProTechTPS interposing relay to initiate a run state. This

may be done by pressing the RESET button on the front panel of the ProTechTPS (see the

ProTechTPS product manual if module does not reset when the RESET button is pressed).
