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, 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
Each Woodward Electrically Powered Governor (EPG) system includes three
basic parts:

A magnetic pickup (MPU) which senses engine speed from an enginedriven gear.

A speed control which receives the speed signal from the MPU, compares it
to a reference signal, and generates a control signal which the control sends
to the actuator.

An actuator which receives the signal from the control and positions its
output shaft according to this signal. The output shaft is linked to the fuel
control.
There are two EPG models:

The isochronous speed control, which is available with start-fuel limit or dual
dynamics;

The droop speed control, which includes a load sensor and provides droop
control for generator sets.
Different actuator sizes are available for different work output requirements.
Models are available for either 12 or 24 volt systems.

MOUNTING SCREWS
0.250-20 (inch) thread. Minimum mounting screw engagement should be 9.5 mm (0.375
inch). Torque screws to 9–11 N·m (80–100 lb-in).
The speed control is designed to operate within a temperature range of
–40 to +75 °C (–40 to +167 °F). Mount the control in a location with space for
adjustment and wiring access. If mounted on the prime mover, do not expose the
speed control to sources of radiant heat such as exhaust manifolds or
turbochargers. Also choose a protected location so that the control won’t be
damaged when moving the prime mover or when equipment is moving nearby.
Mount the control close to the actuator and battery to meet the wire length
requirements. Allow for adequate ventilation.
The EPG speed control must be mounted on a metal plate that is at the same
ground potential as the case. The case and mounting plate must be grounded to
either the protective earth of the building or, if no protective earth is available, the
frame ground of the engine/skid.

512/24 and 1712/24 use a 10 A fuse.
Polarity not important.
With a balanced load and unity power factor (PF=1), the current transformer should
be wired in the correct potential leg, and must be phased at the control so the
potential at terminal 9 to 10 is in phase with the CT from terminal 11 to 12.
Power source current transformers should be sized to produce a 5 A secondary
current, with maximum generator current. CT burden is essentially 0 VA.
Absolute minimum signal must be 95 Vrms. Absolute maximum signal must be 260
Vrms. Potential transformer burden is 20 VA.
This control contains an internal current transformer. This transformer must be
connected across the power source transformer whenever the unit is running to
prevent lethal high voltage from developing on leads to these terminals.
On systems without a neutral, the voltage at terminal 9 to 10 is 1.73 times N2/N1
times the line-to-line voltage.

Installation and Troubleshooting
Installation
Speed Control
The speed control box should be mounted on the control panel, often on the
same skid as the engine. It is not designed for installation on the engine. Provide
space for adjustment, wiring access, and ventilation. Choose a location that
protects the control from being bumped and that the wiring harness will reach.
The installation should allow for adequate air circulation to the control box and
have an ambient temperature of –40 to +75 °C (–40 to +167 °F).
Actuator
Install the actuator solidly, and install a linkage with the correct configuration to
provide an almost linear relationship between change of actuator position and
change in engine power output. In most cases use about 2/3 of the actuator
rotation between minimum and maximum fuel. The engine fuel control usually
provides the minimum and maximum stops. The minimum and maximum stops
on the actuator may be used, if necessary (see Figure 2-1). If the actuator is
controlling the speed-setting shaft of a mechanical governor, use the actuator
stops to limit the travel of the linkage. Set the minimum stop for 5% below rated
speed at no load, and set the maximum stop for rated speed plus 3% more than
the droop of the governor. The actuator is designed to operated in ambient
temperatures of –40 to +82 °C (–40 to +180 °F). Installation should avoid sources
of excessive heat.
Do not pressure wash sealed bearings—you may force dirt inside
them, shortening their life. If the actuator is exposed to weather,
mount it with the clockwise end higher, if possible.
Magnetic Pickup (MPU)
Install the magnetic pickup on a rigid bracket or housing so its tip is near an
engine-driven gear. This gear must be made of a ferrous material that reacts to a
magnetic field. Adjust the MPU for 0.25 to 1.0 mm (0.010 to 0.040 inch) between
the gear and the MPU at the closest point.
Electrical Connections
Connect the system as shown in the appropriate wiring diagram (Figures 1-2,
1-3, 1-4). See the appropriate manual for wiring of accessories. Connect the
speed control to system ground.

EPG Electrically Powered Governor
Manual 82329
Shields
Use twisted-pair, shielded wire where the wiring diagram shows. Each shield
must be grounded only at the end nearest the control. Do not ground both ends
of a shield. Tie all shields to the same ground point. When passing a shield
through a terminal block, connect the shield to its own terminal. Do not ground
the shield at the terminal block. Do not solder to braided shields.
Damage to the speed control will occur if the battery is disconnected
while the alternator or battery charging device is energized and
connected to the control.
Installation Check and Troubleshooting
All Units
To verify correct system operation after installation and any time trouble occurs,
do the following checks in the order given. Disconnect all accessories. Leave the
IDLE/RATED switch or jumper connected. On isochronous EPGs, jumper
terminal 7 to terminal 8, and terminal 11 to terminal 12. On EPGs with droop,
leave terminals 9, 10, 11, and 12 disconnected with CT and PT wires properly
secured for safety. On EPGs with dual dynamics, leave terminals 7 and 8 open to
select primary (fast) dynamics.
If the system does not respond as indicated, find the fault and correct it.
1.
Check electrical connections:
Correct?
Tight?
2.
Magnetic Pickup:
Correctly adjusted?
Tight?
Resistance of 50–350 Ω?
3.
Close the IDLE/RATED switch (or install a jumper).
4.
Turn the governor power on: (Do not start the engine or turbine.)
Fuse OK?
Actuator shaft settles in minimum fuel position?
5.
Battery Voltage:
10 to 16 Vdc for model 512, 1712?
20 to 32 Vdc for model 524, 1724?

Gain and Stability
6.
Set the IDLE potentiometer (pot) (if used) to mid-position.
7.
Set the RATED speed pot fully counterclockwise (to minimum speed
setting).
8.
Set the GAIN and STABILITY pots to mid-position.
9.
Set START FUEL LIMIT clockwise (if applicable).
10. Start the engine or turbine, following manufacturer's instructions.
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.
Verify:

MPU voltage between terminals 5 and 6 at least 1.5 Vrms while cranking?
(For small gears, it may be necessary to decrease the MPU clearance). Do
not decrease below 0.25 mm (.010 inches).

Actuator should go to maximum fuel position when the starter turns engine
or turbine. (If applicable, Start Fuel Limit must be fully clockwise.)

When the engine or turbine starts and comes to speed, the actuator arm
should move toward minimum-fuel position.
11. Adjust the GAIN pot to the stable region between low-frequency and highfrequency oscillation.
12. If there is a low-frequency oscillation which does not stop when the GAIN
pot is adjusted, turn the STABILITY pot slightly clockwise and try the GAIN
pot adjustment again. Continue adjusting the STABILITY pot slightly
clockwise, then readjusting the GAIN pot, until the engine runs at a steady
speed.
If there is a high-frequency oscillation which will not stop, even when the
GAIN pot is fully counterclockwise, adjust the STABILITY pot slightly
counterclockwise until the high-frequency oscillation stops.
Speed Settings
13. Adjust the RATED SPEED pot for the desired rated speed.
14. Set the IDLE SPEED pot for the desired idle speed.
15. Close the IDLE/RATED switch.
16. Adjust transient response. Simulate a transient by manually bumping the
linkage.
To decrease settling time (may increase ringing) after a transient, turn the
GAIN pot clockwise slightly, then turn the STABILITY pot as required to
eliminate oscillation and to obtain desired response. Repeat if necessary.
Woodward

EPG Electrically Powered Governor
Manual 82329
To decrease ringing (will increase settling time) after a transient, turn the
GAIN pot counterclockwise slightly, then turn the STABILITY pot as required
to eliminate oscillation and obtain desired response. Repeat if necessary.
17. Select alternate dynamics and alternate fuel, if applicable. Repeat this step
as necessary.
This completes the check of units without droop. For units with droop, do the
following additional steps.
Droop Adjustment (only for units with droop)
The EPG Load Sensor Module cannot be used with the EPG model
that has internal droop.
For Isolated Load:
1.
Connect the PT wires to terminals 9 and 10 and the CT wires to terminals
11 and 12. Verify correct polarity (see the wiring diagram).
2.
Adjust the RATED SPEED pot for rated speed with no load.
3.
Apply 100% rated load or available load.
If engine speed increases when load is applied, there is danger of
death, personal injury, or damage to equipment. Be prepared to
control the engine or turbine manually by forcing the actuator arm
toward the minimum-fuel position. If engine speed does increase
with load, reverse either the PT or CT input wires.
4.
Adjust the DROOP pot to give a speed of:
Rated Speed -
%DroopxRated Speed %Load
x
100%
100%
Example 1:
The generator set is a 60 Hz unit with an isolated load. If the desired droop
is 5% and the generator set can be run at 100% load, then the speed at full
load would be 57 Hz.
Example 2:
It is again desired to set the droop of the same generator set to 5%, but this
time the generator set cannot be run at 100% load. The generator set is
therefore run at 50% load and the speed (in step 3) would be 58.5 Hz.
Example 3:
The generator set is a 60 Hz unit that will be paralleled with an infinite bus. If
the desired droop is 5% and the generator set can be run at 100% load, the
speed at which the generator is run (in step 2) would be 63 Hz.
12
Woodward
Manual 82329
EPG Electrically Powered Governor
Example 4:
It is again desired to set the droop of the same generator set to 5%, but this
time the generator set cannot be run at 100% load. It has been decided to
run the generator set at 50% load, so the speed (in step 2) at which the
generator set is run would be 61.5 Hz. In step 7, the DROOP pot is then
turned counterclockwise only until the load is 50%.
Paralleled with Infinite Bus:
1.
Run the generator set unloaded at rated speed.
2.
Adjust the RATED SPEED pot to give a speed of:
Rated Speed -
%DroopxRated Speed %Load
x
100%
100%
3.
Mark the position of the pot and return to rated speed.
4.
Turn the DROOP pot fully clockwise (for maximum droop).
5.
Synchronize the generator to, and parallel it with, the bus.
6.
Return the RATED SPEED pot to the mark made in step 3.
7.
Turn the DROOP pot counterclockwise (decreasing droop) until load is
100% (or the desired % of load).
