Electrostatic Discharge Awareness

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
Electrostatic the control turned off, contact a grounded surface and maintain
Precautions 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, the 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. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.

General Information

Introduction
This manual describes the Woodward ProAct™ Analog Actuator for engine
applications. This manual provides installation instructions, describes the control,
and explains the configuration (programming), adjustments (service mode), and
hardware specifications. This manual does not contain instructions for the
operation of the complete engine system. For engine or plant operating
instructions, contact the plant-equipment manufacturer.

How to Use This Manual

The following summarizes how to install a ProAct actuator into a new or existing
system.
 Unbox and inspect the hardware for any visible damage caused during
shipping.
 Mount the actuator and linkages following the procedures and
recommendations in Chapter 2.
 Wire the actuator—see Chapter 3.
 Refer to Chapter 4 for guidelines on calibration and setup.

The actuator must be properly set up using the CAL/CONFIG routine

prior to starting the engine.

Description
The ProAct Analog is a family of electric actuators with integral drivers intended
to be mounted on-engine to control various functions including (but not limited
to): fuel rack positioning, timing control, and throttle valve and wastegate
positioning. The device is effectively a positioner which will accept a desired
position signal from another device in the system, such as a speed control, and
drive to that position. Each unit includes an analog driver interface capable of
controlling the actuator, and provides a signal that represents throttle position.

The ProAct Analog actuator can be commanded to a position via 4–20 mA,
0–200 mA or PWM interfaces. In addition, given an on board position feedback
device, the actual position is available to the system through a position output
signal. This is a highly filtered signal and may not be suitable for closed loop
operation.

Each member of the ProAct Analog family has a different input signal
specification or bi-directional torque output capability as described in Chapter 9
(Specifications) and shown in Table 1-1. In addition, each actuator has a nominal
rotation of 75° at the output shaft. It can be mounted in either a base mount or
flange mount configuration. The units are designed to operate in an on-engine
environment and can therefore withstand high levels of vibration and temperature
extremes. The details of these environmental limits can be found in the
Environmental Specifications section in Chapter 9.

Table 1-1. Input Signal Specification

As described in Regulatory Compliance, the ProAct Analog family of actuators

meets CE marking requirements.

Controller Overview
The position controller interface software is executed on a 16 MHz 6805 8-bit
microcontroller onboard the ProAct Driver. Internal current and position sensors
provide feedback for closed-loop position control. The driver interfaces with an
external speed control via a position demand. The position demand can be an
analog signal (4–20 mA or 0–200 mA) or PWM signal. The ProAct control
monitors all available signals, internal and external, and provides actuator
shutdown if any faults are detected. An analog output provides actual position
indication. Figure 1-1 provides a functional overview of the ProAct Analog.

The ProAct control is field configurable, which allows a single basic design
consisting of four part numbers to be used in many different applications. The
driver must be configured and field calibrated to the specific engine. Figure 1-2
provides an overview of the ProAct Analog driver I/O (inputs/outputs).

Mechanical Setup
Mounting
The ProAct Analog platform is base mounted to tapped holes on the bottom of
the actuator or flange mounted utilizing through-holes provided (see Figure 2-2).
The unit can be mounted in any orientation. All exterior and mounting dimensions
and exterior fasteners are metric. See Chapter 2 (Installation) for details on
mounting and installation.

Output Shaft
The ProAct Analog family output shafts are standard US-customary sizes with
toothed serrations.

Rotation

All ProAct Analog actuators have 73–77 of available travel. The max fuel
direction of this travel is configurable in the clockwise or counterclockwise
direction.

Mechanical Stops
Internal mechanical actuator stops will only survive a maximum kinetic energy of
0.011 J (0.097 in-lb). If the actuator internal stops are used, the load inertia
should not exceed 3.76E-3 in-lb-s² (4.25E-4 kg-m²). See Chapter 2 (Linkage) for
details on actuator inertia and internal stops. In service, electrical and engine
stops should be set inside the actuator stops. Electrical stops are set via the
CAL/CONFIG routine.

Electrical Connections
There is one interface on the circuit board. Refer to Figure 3-1 for details on
ProAct actuator wiring.

* NOTE–If an external 5 volt source is used, the position output signal is ratiometric to that
source. If no external supply is applied, the position signal is referenced to the internal 5
volt source.
Table 1-2. Board Connections

Position Command Input

There are three possible position command signals. See the table below for an
overview of the signals and corresponding input signal to actuator position. All
adjustments to the four different part numbers (Table 1-1) are done via the
CAL/CONFIG routine. All circuits are protected against short circuit to battery
negative. These short circuits will not cause damage to the control.

The response of the actuator when the input signal is outside the nominal range
is model-dependent. PWM models will disable the coil drive until the PWM input
signal returns to a nominal range value. At inputs less than 20 mA, the current
model will drive into the min stop, and at inputs greater than 180 mA, it will drive
into the max stop. Current models will continue to drive (to min stop) with no
input signal applied.

Inputs/ Outputs (I/O)

The following Inputs/Outputs (I/O) are available in the ProAct Analog:
 power input
 1 analog input
 1 PWM input
 1 analog output
Refer to the control wiring diagram (Figure 3-1) for wiring overview. Refer to
Chapter 3 for wiring details.

Power Input
The input power has an operational range of 18–32 Vdc, nominal 24 Vdc. Please
reference the electrical specification in Chapter 9 for input power and current
requirements.

Analog Input for Position Demand

The analog input model has available both a 4–20 mA input and a 0–200 mA
input. The input is selected using the appropriate input pin on the customer
interface connector (Table 1-2)—pin B for 4–20 mA and pin E for 0–200 mA. The
reference pin is C.

PWM Input for Position Demand

The PWM input model accepts a 100 to 3000 Hz input signal of 7 to 32 volts
peak voltage (referenced to unit battery ground). The PWM input duty cycle
minimum and maximum are field calibrated to match the controller sending the
demand. This input is applied at pin B of the external connector with the
reference at pin D (Power GND).

Low Power Standby Mode (PWM models only)

When the input is opened, the driver goes into a low power standby mode. The
low power standby mode causes the motor driver to be de-activated to minimize
the power consumption of the driver.

The input must be connected to operate the unit. When open, the unit
is forced into a non-operational shutdown state.

Alternatively, if it is desired to completely reduce the power consumption of the

driver to zero, power can be completely disengaged from the unit with a
customer installed switch on the input power.

0.5–4.5 V Analog Output for Indication of Actual Position to an

External Device
An analog output of 0.5 to 4.5 V corresponds to 0% and 100% actuator travel,
respectively. Offset and gain adjustments are made automatically when the
calibration routine is executed (see Chapter 7 for procedure).

Woodward 11
ProAct Analog Manual 26147

Chapter 2
Hardware Installation

This chapter provides instructions on how to mount and connect the ProAct™
Analog actuator into a system. Hardware dimensions are provided for mounting
the ProAct package to a specific application.

Unpacking
Be careful when unpacking the actuator. Check the unit for signs of damage,
such as bent or dented panels, scratches, and loose or broken parts. Notify the
carrier and Woodward if damage is found.

Mounting Location
The ProAct Analog actuator is designed to operate within an ambient
temperature range of –40 to +74 °C (–40 to +165 °F). Mount the driver close
enough to the battery to meet the wire-length requirements (see wiring
instructions in Chapter 3).

The ProAct actuator is designed for installation on the engine. The ProAct
actuator will generate heat, especially when stalled or during other conditions
requiring maximum torque output. The installer must consider the heat
conductivity of the installation bracket, and the operating temperature of the
ultimate heat sink to which the bracket will be attached. Generally the heat
transfer abilities of aluminum and low-carbon steel are better than those of high-
carbon steel or stainless steel.

A minimum gap of 0.5 mm must be maintained between the support

bracket and electronics enclosure (see Figure 2-2a). This is necessary
because the enclosure is supported on vibration isolators to filter out
high-frequency vibrations from reaching the electronics. If the
enclosure contacts the bracket, the isolation is defeated and may
reduce the electronics operating life.
If spacers are used to achieve the necessary gap, Woodward
recommends maximizing the surface contact area of the spacers to
maximize heat transfer between the ProAct and mounting bracket.

Actuator Application Guidelines

The following sections include environmental guidelines for applying the ProAct
Analog. By adhering to the limitations and recommendations set forth in these
sections, the customer will realize the full functionality of the actuator and
improve its overall reliability.

12 Woodward
Manual 26147 ProAct Analog

Mounting
Models I and II actuators may be installed on a bracket in either base or flange
mount configuration. The base mount configuration requires the use of four
M8x1.25 screws with a minimum engagement of 16 mm. The flange mount
configuration requires the use of four M8 screws through the flange. Whether
base mounting or flange mounting the actuator, torque the four M8 screws to
22.6 Nm (200 lb-in). The actuator may be mounted in any attitude.

The ProAct Analog weighs approximately:

Model I 11 kg (25 lb)
Model II 11 kg (25 lb)

The bracket and attaching hardware must be designed to hold the weight and to
withstand the vibration associated with engine mounting. Additionally, the bracket
must be designed to provide a heat sink (heat transfer) from the actuator to the
engine block as described in the Mounting Location section.

As shown in Chapter 9, ProAct Analog Specifications, the ProAct actuators have

been designed for and verified to a given accelerated life vibration test level at
the mounting surface of the actuator. The user should be aware that in any
application, bracket design can significantly change the vibration levels at the
actuator. Therefore, every effort should be made to make the bracket as stiff as
possible so that engine vibrations are not amplified, creating an even more
severe environment at the actuator. Additionally, when possible, orienting the
actuator shaft parallel to the crankshaft of the engine will often reduce the
vibration load on the actuator's rotor system in reciprocating engine applications.

Fuel Position Stops

Diesel Stops—Diesel installations will generally use the fuel system minimum
and maximum position stops. Diesel engine racks are normally designed to
provide the minimum and maximum stops without binding. The actuator's stops
must not prevent the actuator from driving the fuel linkage to the minimum and
maximum positions. The linkage should be designed to use as much actuator
travel as possible, without preventing minimum and maximum fuel positions (see
Figure 2-1).

Gas Engine Stops—Butterfly valves in carburetors will often bind if rotated too
far toward minimum or maximum. For this reason, the stops in the actuator
should be used at both minimum and maximum positions. Note that the actuator
internal stops will allow up to 1.5 degrees of additional rotation in both directions
during impact (see Figure 2-1).

The engine must always shut down when the actuator is at the minimum stop.

Linkage
Proper design and installation of the linkage from the actuator to the engine is
necessary for the unit to provide the best control possible.

Certain applications with low inertia may be unstable with high impulse loads and
may require additional system inertia. See troubleshooting guidelines or contact
Woodward for more information.

Ensure that the actuator has ample work capacity to control the fuel supply under
maximum load conditions.

Manually stroke the fuel-control linkage from stop to stop as if the actuator were
moving it. The linkage must move freely, without friction and backlash. Lubricate
or replace worn linkage or fuel control parts as required.

The actuator contains no internal return spring, therefore an external

positive shutdown is necessary in the event of a loss of power to the
actuator.

The actuator’s maximum slew rate can place stress on the fuel
system stops and on the linkage between the actuator and the fuel
system. The maximum actuator speed is 1000 degrees per second in
both increase and decrease fuel directions.

Woodward 15
ProAct Analog Manual 26147
The Mass Moment of Inertia (MMOI) for the ProAct Analog actuators are:
Model I, II 4.9E-3 lb-in-s² (5.5E-4 kg-m²)

The fuel system stops must be adequate to absorb the actuator MMOI in addition
to the linkage inertia without damage.

ProAct actuator internal stops are designed to absorb 0.011 J (0.097 in-lb) of
kinetic energy with 1.5 degrees of over travel. If the actuator stops are used, the
load inertia must not exceed 3.76E-3 in-lb-s² (4.25E-4 kg-m²), and the linkage
must be designed to allow the 1.5 degrees of over travel on each end.

Use of good rod-end connectors with as little free play as possible is essential.
Select rod ends which will remain tight and wear well during the nearly constant
movement associated with precise speed control. Low-friction, long-wearing rod
ends are available from Woodward.

The linkage travel and offset should provide travel below steady state idle fuel
and above steady state full load fuel. Woodward “standard” is for no load to full
load actuator stroke (and control output) to provide approximately 2/3 of the stop-
to-stop travel. As an example, 60° linkage travel should be 10° idle and 50° max
load.

The link connecting the actuator lever to the fuel-control lever must be short and
stiff enough to prevent flexing while the engine is running.

Typically, in a linkage system, there may be links and levers which are supported
by customer-supplied bearings. Additionally, there will typically be a section of
the linkage where the mass is supported fully by the actuator output shaft. Please
note when designing these systems that each ProAct Analog actuator is
designed to accept 1.2 kg (2.6 lb) of additional mass at a maximum vibration
level of 10 Gs. Exceeding this mass or vibration level may damage the actuator's
rotor system and shorten the life of the actuator.

Actuator levers are available from Woodward which allow adjustment of the rod
end locations with respect to the center of the actuator shaft. The lever used
must have a 0.625-36 serration.

Adjust the location of the rod end on the lever to achieve the desired actuator
rotation between minimum and maximum positions. The linkage should be set to
use as much of the 75 degrees as possible (at least 60 degrees minimum). To
increase the amount of actuator rotation, move the rod end closer to the actuator
shaft or farther away from the shaft controlling the fuel flow. To decrease the
amount of actuator rotation, move the rod end farther from the actuator shaft or
closer to the shaft controlling the fuel flow.

The actuator must be stroked using the CAL/CONFIG procedure any

time the valve stops or linkage is adjusted.

Follow the procedure in Chapter 7 on Adjusting User Stops and

Dynamics.

Refer to Table 1-2 for the customer interface wiring to the external connector, the
representative interface schematic (Figure 2-2), and the Specification section of
the manual for the hardware specifications.

When the ProAct is to be configured with a user-constructed external connector,

all inputs and outputs to the ProAct actuator are accessed beneath the end cover
which is fastened with 6 M4x10 mm, screws (see the outline drawing, Figure
2-2). The end configuration must use the cover with all screws and the seal in
place.

Input power is connected to pin 1(+) and pin 2(–) of the terminal strip.

The terminal block is a screwless cage clamp style block. The spring clamp can
be actuated by pressing down on the thumb levers integral to the block. The
terminal block accepts wires from 0.20—3.3 mm² (24—12 AWG) wire. Two 0.82
mm² (18 AWG) or three 0.5 mm² (20 AWG) wires can easily be installed in each
terminal. Wire for the terminals should be stripped 8–9 mm (0.3 inch).

Cable Shield Termination

The ProAct control is designed for operation with shielded cables. Shielding is
required for the command signal lines and the sensor output and reference lines.
Cable shield ground termination must be performed as shown in Figure 2-2.
Command signal shield must be grounded as recommended on the command
signal source, and the sensor signal shield must be grounded to the device’s
ground lead (pin D).

Grounding and Ground Connections

The multiple ground connections are provided for variations in local wiring codes.
An internal power ground connection (see Figure 3-1) and an external ground
connection (other than the mounting) are both provided. Refer to the external PE
Ground connection identified in Figure 2-2b.

Customers must use the grounding point that meets local authority
approval requirements.

Power Source
Power source output must be low impedance (for example, directly from
batteries).

Run an insulated wire directly from the positive (+) battery terminal to a fuse and
on/off switch, then to the correct connection on the driver (see Figure 3-3). Run a
second insulated wire directly from the negative (–) terminal of the battery to the
driver. Neither of these connections needs to be shielded.

Run the power leads directly from the power source to the control. DO NOT
POWER OTHER DEVICES WITH LEADS COMMON TO THE CONTROL (see
Figures 3-3 & 3-4). If the power source is a battery, be sure the system includes
an alternator or other battery-charging device.

When the engine is shut down, the driver powers the actuator into the minimum
stop. If the battery charging system is off when the engine is shut down, this will
cause the battery to be drained. In this case, the power to the ProAct must be
turned off with a switch or relay. Any such switch or relay must be interlocking to
prevent starting the engine when power to the actuator is shut off.

Do not remove power from the driver for normal shutdown

procedures. All actuator position commands should come from the
control unit, through the driver, to the actuator. Engine overspeed is
possible if power is removed from the driver while the engine is
running.

To prevent possible damage to the control, or poor control

performance resulting from ground loop problems, follow these
instructions.

Input Power Fusing

The input power must be fused. Failure to fuse the ProAct could,
under exceptional circumstances, lead to personal injury, damage to
the control valve, and/or explosion.

Recommended fuse ratings are listed below.

Model I: 5 Amp Fast Acting Fuse

Model II: 15 Amp Fast Acting Fuse

All fuses should have a voltage rating of at least 100 V and an I²t rating greater
than 2 A for 2 seconds. A typical fast acting fuse will meet these ratings.

Input Power Wire Length Considerations

Input power wire lengths should be as short as possible. Maximum wire lengths
are shown in Table 3-2.

If the recommended cable distances between battery and actuator

are exceeded, torque output will be reduced and the unit may be
damaged.

Setup, Calibration, and Adjustments

General Description
Setup and calibration are provided through test points located on the printed
circuit board (see Figure 4-1).

Setup
The basic setup consists of actuator configuration and stroking. Configuration is
not required on most OEM-supplied units. Configuration is performed using the
Config table in the Appendix.

Actuator stroking is required to ensure that 0–100% actuator travel provides an

equivalent valve position.

The setup, configuration, and stroking adjustment must be performed when the
engine is shut down.

Calibration
The ProAct™ control may be calibrated at any time, and calibration takes place
whenever a configuration change is made.

To calibrate or make a configuration change, the engine must be shut down.

Chapter 5
Description of Operation

Position Control
The ProAct™ Analog provides closed-loop position control based on an internal
position sensor and the desired position demand signal. Position and current
controllers are utilized to position the output. Position control is provided using a
customer's position demand and an internal driver output while using an internal
position feedback sensor. The driver provides a 0.5–4.5 V analog output for
indication of actual position. Field calibration is available at any time by utilizing
the appropriate jumpers. Calibration must be done with the engine shut down.

Figure 5-1. Controller Overview

Position Demand
The position demand is provided by a single input (factory set for either PWM or
current [current is jumper selectable for either 4–20 mA or 0–200 mA]). The
position demand can be provided by one of two signal sources: analog or PWM
depending on which part number is in use (see Table 1-1). Failure of the position
demand signal will cause the ProAct Analog to shut down and remain shut down
until a valid signal is received.

Driver Output and Position Feedback

If the internal position or current sensor is out of range, the actuator is put into
the shutdown state. Upon power-up, the unit will stay disabled until the problem
is rectified and a position command signal and current signal have been received
in the proper range.

Woodward 25
ProAct Analog Manual 26147

Drive Current Limitations

The current to the coil is limited to prevent damage. A transient and a steady
state limit are used. The transient current limitation is active during a transition in
position output. After a short delay (about 0.25 seconds), the steady state limit is
activated if desired position is not reached. The transient and steady state limits
are not adjustable, but are based on the actuator type. The nominal transient and
steady current limits for the ProAct actuators are:
transient steady-state
current limit current limit
Models I, II 12 A 6A

User Operating Modes

User-Calibration (Rigging)
The User Calibration mode provides the capability to calibrate the min and max
position. This calibration must be done prior to operation of the unit. Once
performed, this procedure stores the active min and max positions into non-
volatile memory where it is retained until a new calibration is performed.

Configuration
The Calibration Routine provides the capability to alter the configuration of the
output shaft (CW/CCW) and the polarity of the TPS output signal. The unit must
be in a shutdown state to change the configuration.

26 Woodward
Manual 26147 ProAct Analog

Chapter 6
Diagnostics

Shutdowns Detection
A shutdown condition forces the actuator to the power down state regardless of
the demanded position. When the shutdown condition no longer exists, the driver
automatically returns to a non-shutdown state, following the Position Demand
input command. The shutdown condition does not require a “reset” command.

During shutdown, the actuator torque drops to minimum and an

external spring is required to drive the position to minimum.

Software Setup

Configure Mode Parameters

The Configure/Calibration Mode is used to set up the parameters for the specific
application of the ProAct™ control. For example, the direction of shaft rotation,
type of input, and TPS output polarity selections are set using the
Configure/Calibration mode. See Table 7-1.

Adjusting User Stops

Introduction
The User Calibration mode provides the capability to set the min and max
position to match the rigging of the actuator and valve. This calibration must be
done prior to operation of the unit. If this procedure is not done, the actuator will
be defaulted such that 0–100% position demand will correspond to 0–75 degrees
rotation. Refer to Figure 7-1. Once the user calibration is performed, this
procedure stores the active min and max positions into non-volatile memory
where it is retained until a new calibration is performed. Be sure to remove all
calibration/configuration jumpers before restarting the unit.

An improperly calibrated control could cause an overspeed or other

damage to the prime mover. To prevent possible serious injury from
an overspeeding prime mover, read this entire procedure before
starting the prime mover.

An unsafe condition could occur with improper use of the

calibration/configuration procedure. Only trained personnel should
have access to this procedure.

ProAct Calibration Routine

To enter the User Calibration mode, the unit must be shut down and the
appropriate jumpers must be connected. To set output shaft direction (CW/CCW)
and throttle position sensor (TPS) output polarity, connect the test points in
accordance with the following table. Refer to Figure 4-1 for test point (TP)
locations.

Output Shaft 0–200 mA / PWM 4–20 mA

NOTE—PWM input and current input (0–200 mA/4–20 mA) are different part numbers.
The input signal configuration cannot be field modified.

Table 7-1. Jumper Connections Used for Calibration

28 Woodward
Manual 26147 ProAct Analog
To enable the calibration routine, connect a jumper from TP3 to TP6 for 0–200
mA/PWM input or TP3–TP4 for 4–20 mA input. Connect additional test points as
necessary to change the output shaft direction and TPS polarity—see Table
7-1. See Figure 4-1 for test point locations. When power is applied to the unit, the
microprocessor will enter the calibration routine. The output shaft will sweep
slowly from stop to stop in order to find the end points, and then return to the mid
position. It is not necessary to apply an input signal during this time as the
microprocessor assumes 0.5 to 4.5 V as its input. When the calibration is
complete, turn off the power, disconnect all jumpers, and make sure that the
input signal is applied. When power is reapplied the unit will be in the operate
mode.

Troubleshooting

Introduction
Improper engine operation is often the result of factors other than governor
operation. This chapter gives tips about engine problems which can resemble
governor problems. Make sure the engine is operating correctly before making
any changes in the governor. The following troubleshooting guide is an aid in
isolating trouble to the control box, actuator, wiring, or elsewhere.
Troubleshooting beyond this level is recommended ONLY when a complete
facility for control testing is available.

Attempting to correct engine or load problems with untimely governor adjustment

can make problems worse. If possible, isolate the governor from the engine to
determine if the problem is with the governor and not with the engine or the load
on the engine. Governor faults are usually caused by problems in the installation
or the linkage between the actuator and the engine.

Carefully review all the wiring connections, the power supply, and the linkage
before making any adjustments to the actuator or driver. Always check the fuel-
control linkage from stop to stop as if the actuator were moving it. The linkage
must move freely without friction and without backlash. Some fuel controls will
present problems at particular fuel or rack positions because of a hesitation or
binding in the linkage.

Fuel supply and injector conditions can also present problems which resemble
governor problems. On spark-ignited engines, distributor, coil, points, and timing
problems can all cause improper operations which may resemble faulty governor
control.

The control can be damaged with the wrong voltage. When replacing
a control, check the power supply, battery, etc., for the correct
voltage.

Troubleshooting Procedure
This chapter is a general guide for isolating system problems. The guide
assumes that the system wiring, soldering connections, switch and relay
contacts, and input and output connections are correct and in good working
order. Make the checks in the order indicated. Various system checks assume
that the prior checks have been properly done.

General System Troubleshooting Guide

The following is a general troubleshooting guide for areas to check which may
present potential difficulties. By making these checks appropriate to your
engine/turbine before contacting Woodward for technical assistance, your system
problems can be more quickly and accurately assessed.

Actuators
 Is the actuator wiring correct?
 Is the direction of the stroke correct? (This is configured using the
CAL/CONFIG routine.)
 Has the feedback signal been calibrated? (This is calibrated at the factory.)

Linkage
 Is there slop or lost motion?
 Is there misalignment, binding, or side loading?
 Is there visible wear or scarring?
 Does the linkage move smoothly?

Valves
 Does the valve move through its proper stroke smoothly?
 Does the valve travel its full stroke?
 Can mid-stroke be obtained and held?
 Does the valve fully seat (close) before the governor reaches full minimum
stroke?
 Does the valve fully open before the governor reaches maximum stroke?

Mechanical Troubleshooting Guide

Linkage and Actuator Stroke
Use as much of the 75 degrees of actuator stroke as possible. Carefully follow
the guidelines in the Driver Adjustments section of Chapter 2 in making linkage
arrangements. Using less than optimum actuator movement will make stability
more difficult, and will make the actuator more sensitive to external loading
forces and friction.

Actuator exhibits “hunt” or large limit cycle.

 Check for loose terminal lever.
 Check for loose or worn linkage.
 Verify correct mounting hardware.
 Verify mounting bolts are tightened to appropriate torque values.

Unable to rotate stand-alone actuator in unpowered condition

 Internal mechanical failure—replace actuator.

Electrical Troubleshooting Guide

Analog Input
If the Analog input is not functioning properly, verify the following:
 Measure the input voltage on the terminal block. It should be in the range of
0–5 V.
 Verify that there are no or minimal ac components to the Analog Input
signal. AC components can be caused by improper shielding.
 Check the wiring. If the inputs are reading 0 or the engineering units that
correspond to 0 mA, look for a loose connection at the terminal blocks and
disconnected or misconnected cables. Check for proper wire installation on
the terminal block, pin #3 for 0–200 mA or pin #5 for 4–20 mA.
 If all of the inputs are reading high, check that the power is not connected
across the input directly.
 Check the configuration to ensure that the input is configured properly. This
can be done by running the calibration/configuration routine.

Analog Output
If the Analog output is not functioning properly, verify the following:
 Check to ensure that voltage is between 0.5 and 4.5 V for full output stroke.
 Check the wiring, look for a loose connection at the terminal block pin#6 and
disconnected or misconnected cables.

Performance Troubleshooting Guide

If the actuator buzzes, or has a fast limit cycle:
 Check for loose linkage.

If the actuator has a slow limit cycle:

 Free stuck linkage or load.

Actuator has steady state position error:

 Re-run stop position calibration.
 Supply voltage too low.
 Actuator load too large or actuator too small.
 Free stuck linkage.
 Actuator fault – replace actuator.
