Warnings and Notices

Important Definitions

This is the safety alert symbol used to alert you to potential personal injury hazards. Obey all

safety messages that follow this symbol to avoid possible injury or death.

DANGER - Indicates a hazardous situation, which if not avoided, will result in death or serious injury.

WARNING - Indicates a hazardous situation, which if not avoided, could result in death or serious

injury.

CAUTION - Indicates a hazardous situation, which if not avoided, could result in minor or moderate

injury.

NOTICE - Indicates a hazard that could result in property damage only (including damage to the

control).

IMPORTANT - Designates an operating tip or maintenance suggestion.

Overspeed /

Overtemperature /

Overpressure

The engine, turbine, or other type of prime mover should be

equipped with an overspeed shutdown device to protect against

runaway or damage to the prime mover with possible personal injury,

loss of life, or property damage.

The overspeed shutdown device must be completely independent of

the prime mover control system. An overtemperature or

overpressure shutdown device may also be needed for safety, as

appropriate.

Personal Protective

Equipment

The products described in this publication may present risks that

could lead to personal injury, loss of life, or property damage.

Always wear the appropriate personal protective equipment (PPE) for

the job at hand. Equipment that should be considered includes but is

not limited to:

Eye Protection

Hearing Protection

Hard Hat

Gloves

Safety Boots

Respirator

Always read the proper Material Safety Data Sheet (MSDS) for any

workin

fluid

(

)

and compl

with recommended safet

equipment.

Start-up

Be prepared to make an emergency shutdown when starting the

engine, turbine, or other type of prime mover, to protect against

runaway or overspeed with possible personal injury, loss of life, or

property damage.

Electrostatic Discharge Awareness

Electrostatic

Precautions

Electronic controls contain static-sensitive parts. Observe the

following precautions to prevent damage to these parts:

Discharge body static before handling the control (with power to

the control turned off, contact a grounded surface, and maintain

contact while handling the control).

Avoid all plastic, vinyl, and Styrofoam (except antistatic

versions) around printed circuit boards.

Do not touch the components or conductors on a printed circuit

board with your hands or with conductive devices.

To prevent damage to electronic components caused by improper

handling, read and observe the precautions in Woodward manual

82715

, Guide for Handling and Protection of Electronic Controls,

Printed Circuit Boards, and Modules.

Follow these precautions when working with or near the control.

1. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic

materials. Wear cotton or cotton-blend materials as much as possible because these do not store

static electric charges as much as synthetics.

2. Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary.

If you must remove the PCB from the control cabinet, follow these precautions:

Do not touch any part of the PCB except the edges.

Do not touch the electrical conductors, connectors, or the components with conductive devices

or with your hands.

When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in

until you are ready to install it. After removing the old PCB from the control cabinet, immediately

place it in the antistatic protective bag.

Explosion Hazard

Do not remove covers or connect/disconnect electrical connectors

unless power has been switched off or the area is known to be non-

hazardous.

Substitution of components may impair suitability for Class I, Division

2, or Zone 2 applications.

Risque d'explosion

Ne pas enlever les couvercles, ni raccorder / débrancher les

prises électriques, sans vous en assurez auparavant que le

système a bien été mis hors tension; ou que vous situez

bien dans une zone non explosive.

La substitution de composants peut rendre ce matériel

inacceptable pour les emplacements de Classe I, Division 2

et/ou Zone 2.

Special Conditions for Safe Use

Wiring must be in accordance with North American Class I, Division 2, or European or other international

Zone 2, Category 3 wiring methods as applicable, and in accordance with the authority having jurisdiction.

Use supply wires suitable for at least 10°C above surrounding ambient.

Note: Cables supplied through Woodward meet this requirement.

To assure IP55 ingress protection, attach mating connectors to the actuator’s receptacles

General Information

The ELA actuation system consists of an electronically controlled linear actuator and a digital electronic

positioner for position control on industrial turbine applications. The digital positioner and actuator

combination are capable of precisely positioning the actuator to follow the setpoint signal from the turbine

control system. The actuator position is controlled by regulating the current to a 3-phase brushless DC

motor, which converts the rotary motion to linear motion via a gear reduction system and leadscrew.

Redundant resolver rotary position transducers are used to sense motor shaft position for commutation

and velocity feedback to the digital positioner. Should one resolver fail, the positioner will revert to the

working sensor to maintain operation.

The Woodward Electric Linear Actuator (ELA) includes the following major sub-assemblies:

A high reliability brushless DC motor

A high load capacity roller screw, driven by a spur gear train

Dual motor resolvers for motor commutation and primary position feedback

An LVDT for independent shaft positioning verification

The Woodward ELA design offers the following benefits to the purchaser in comparison to other electric

actuators:

The actuator and model-based controller provide the accuracy, bandwidth and slew times required for

precise control of the guide vanes. No dynamic tuning is necessary during installation or operation.

The highly capable electronic positioner provides comprehensive diagnostic and communication

functions. These features minimize installation and replacement times and improve system

maintainability.

The Woodward actuator is designed to provide high force consistent with heavy industrial equipment.

All power train and electronic components are designed with conservative design margins for high

reliability. The simple and robust design is capable of consistent performance for extended periods in

challenging environments.

The actuator and digital positioner have been designed to achieve extended Mean Time Between

Overhaul (MTBO) goals. These targets have been reached through the conservative rating of parts

and the careful analysis of individual component and system performance.

An integrated Identification Module (ID module) comes in each actuator. This ID module provides key

information specific to the actuator assembly (i.e., identifies the stroke, gear ratio, motor

characteristics, and device startup limits.) The digital positioner electronically queries the ID module

every time it is powered up. This provides for quick and error free initialization of a new actuator or

digital positioner.

The electronic position controller provides for dual power inputs, and options for redundant digital

interfaces for improved reliability.
