Woodward QuickTrip Electro-Hydraulic Trip Block Assembly General

Special Ambient Temperature Considerations

Cold Start Procedure:

If performing a cold-start of QuickTrip in very cold ambient environment conditions 

(temperatures between -40 °C to +15 °C), both the hydraulic oil within the QuickTrip manifold and the QuickTrip manifold itself

must undergo a warmup procedure prior to starting the turbine to ensure the QuickTrip will operate within

specified performance limits. In particular, slew open times increase at lower hydraulic fluid temperatures

due to the higher viscosity (lower fluidity) of the hydraulic oil.

Before starting the QuickTrip, follow the warm-up procedure below:

1. De-energize all QuickTrip modules (valves should be open).

2. Start flow of warm hydraulic fluid through QuickTrip such that the temperature of the oil flowing from

the drain side of QuickTrip is at or above +15 °C.

3. Allow the warm hydraulic fluid to flow through QuickTrip for at least 30 minutes, while maintaining the

temperature at the drain side of QuickTrip at or above +15 °C.

4. Energize all QuickTrip modules.

5. Use the ProTechTPS to run an auto sequence test on QuickTrip (sequentially de-energizing and re

energizing each channel individually).

6. After the auto sequence test is complete, check the trip time log and verify each QuickTrip module

tripped in less than 50 ms.

7. If QuickTrip is to be operated continuously in very cold ambient environment conditions, the hydraulic

oil temperature flowing from the drain side of QuickTrip must be continuously maintained above +15°C.

8. Alternate methods of heating/insulating the QuickTrip and the hydraulic fluid lines upstream from

QuickTrip in very cold ambient environment conditions are recommended and might include the use

of heat tape, heat blankets and insulation.

General

Woodward products covered under Woodward Product and Service Warranty (5-09-0690) are warranted

to be free from defects in materials and workmanship, when installed and used in the manner for which

they are intended, for a period of 18 months from the date of shipment from Woodward, defined in

Woodward's Terms and Conditions.

Repairs and servicing of the QuickTrip must be performed by Woodward or its authorized service facilities

Use of a cable gland or stopping plug that does not meet the hazardous area certification requirements or

thread form or thread size will invalidate the suitability for hazardous locations.

Never remove or alter the nameplate as it bears important information which may be necessary to service

or repair the unit.

QuickTrip Cover Replacement Kit

Servo cover replacement kit may be ordered from Woodward.

Refer to Figure 5-1a which displays the part number. The location and assembly orientation of each kit

component must be installed as depicted in Figure 5-1b using a spanner wrench or Woodward tool

#1013-6603. For additional information see QuickTrip Field Repair Procedure Manual 26842.
