Woodward QuickTrip User Manual

Manual 26815 QuickTrip Electro-Hydraulic Trip Block Assembly
Woodward 50
Restrictions
The user must complete a full functional check of the QuickTrip after initial installation, and after any
modification of the programming of the logic solver or configuration of the device. This functional check
should include as much of the safety system as possible, such as sensors, transmitters, actuators and trip
blocks. When used with the Woodward ProTechTPS, the ProTechTPS has the capability to facilitate the
automatic checkout and periodic maintenance of the safety system. For help on programming, see the
chapters on functionality, configuration and the example applications in the ProTechTPS manual.
The QuickTrip must be used within the published specification in this manual.
Competence of Personnel
All persons involved in the installation and maintenance of the QuickTrip unit must have appropriate
training. In the event that QuickTrip is used with the Woodward ProTechTPS logic solver, all persons
involved in the initial design or modification of the programmable software, installation and maintenance
must have appropriate training. Training and guidance materials include this manual, the ProTechTPS
service tool, and any training programs available at Woodward. See Chapter 7 (Product Support and
Service Options) for more information.
Operation and Maintenance Practice
A periodic proof (functional) test of the QuickTrip is required to verify that no dangerous faults not
detected by external means remain undetected. More information is in the “Proof Testing” section of this
chapter. The frequency of the proof test is determined by the overall safety system design, of which the
QuickTrip is a part. The safety numbers are given in the following sections to help the system integrator
determine the appropriate test interval.
Installation and Site Acceptance Testing
Installation and use of the QuickTrip must conform to the guidelines and restrictions included in this
manual. No other information is needed for installation and maintenance.
Functional Testing after Initial Installation
A functional test of the QuickTrip is required prior to use as a safety system. This should be done as part
of the overall safety system installation check and should include all I/O interfaces to and from the
QuickTrip that are part of the safety system. For guidance on the functional test, see the proof test
procedure below.
Functional Testing after Changes
A functional test of the QuickTrip is required after making any changes that affect the safety system.
Proof Testing (Full Functional Test)
The QuickTrip must be periodically proof tested to ensure there are no dangerous faults present that are
not detected by external diagnostics. The test procedure will set the trip outputs on the module under test
into a trip state (de-energized for a de-energize-to-trip configuration). It is possible to automate several
steps of the proof test procedure shown below using the programmability and test mode configurability of
the ProTechTPS, but the intent of the steps below must be met. If using a different logic solver, consult
the manual for the unit to determine the steps required to implement a proof test for QuickTrip.
With the procedure below, the user can expect 99% test coverage of the dangerous failures that are not
tested by external diagnostics.
