1. GENERAL INFORMATION
1.1 INTRODUCTION
The DYNA 8000, DYNA 8200 and DYNA 8400 governor system
provides an engine governor for speed and power control of
piston and gas turbine engines or steam and water turbines.
The actuator is a simple, proportional, electric solenoid having
a sliding armature whose magnetic force is proportional to input
coil current. The armature glides on anti-friction bearings and is
balanced between the force of its return spring and the magnetic force, thus providing a hysteresis-free linear movement.
The linear motion is converted to an output shaft rotation by a
crank arm.
The hazardous duty DYNA 8000 and DYNA 8400 actuators
provide units that are UL listed for Class I, Division 2, Group D,
hazardous duty applications that are often encountered in the
petroleum or chemical industries. The hazardous duty actuators can be used to provide an engine governor for speed and
power control of piston and gas turbine engines.
1.2 TYPICAL APPLICATIONS
Typical applications are speed governing, remote throttle control, generator sets, power carts and pump set applications.

3. FUNCTIONAL DESCRIPTION
3.1 ACTUATOR
The actuator consists of an electro-magnet with an iron
armature rolling on the center shaft bearings. The actuator is
provided with a return spring which balances the magnetic
force of the armature. When DC current flows in the coil, the
magnetic force tends to move the armature in the stator and
this linear motion is transformed into rotary motion through a
crank arm that forms part of the output shaft.
3.2 CONTROLLER
The electronic controller is the information processing unit of
the governor assembly. It contains electronic components
which process the input signal from the magnetic pickup and
control the engine to the desired speed/RPM set into the
controller. Electronic adjustments are available on the controller for field adjusting the unit as necessary.
3.3 DC POWER SOURCE
The governor system receives its power from a battery or an
AC to DC power supply supplying 12 or 24 VDC ±20% to
match the governor voltage. The average operating current
consumption is 2.5 to 3.5 amperes and the highest consumption is 14.75 amperes during engine start-up or during a large
load change. The power source must be rated above maximum stall current.
3.4 COMPONENT LOCATION
The actuator of the governor assembly is mounted on the
engine next to the fuel system. The magnetic pickup is
normally mounted in the flywheel housing in such a way that
it can count the teeth on the starter ring gear. The controller is
off-mounted or installed in the engine control panel or cabinet.
5
3.5 ISOCHRONOUS OPERATION
3.7 REMOTE SPEED ADJUSTMENT
Isochronous operation is obtained by setting droop potentiometer fully counterclockwise. The DYNA governor is all electric,
and it is normally operated in the isochronous mode; i.e.,
engine RPM is constant (±0.25%) under steady state load
conditions, up to the engine's maximum capability, regardless
of load on the engine.

100%
An optional remote speed selector (DYNS-10000) is available
for adjusting engine RPM from up to 90 meters (300 ft.) from the
engine. See the Electrical Wiring Schematic. The potentiometer can be connected for a narrow (fine) or wide speed range
control.
4. INSTALLATION
4.1 PROCEDURE
4.1.1 Mount the actuator on a suitable rigid steel bracket or
plate.
NOTE
Mounting information and kits are usually available for
a particular engine. Contact Sales Representative.
4.1.2 Set up the linkage and rod end bearings (see 4.2).
4.1.3 Install the speed sensor with SAE threads (magnetic
pickup)*.
*Magnetic pickups with metric threads are available.
Thread — M16 x 1.5 — 6 g. Tap Drill Size — 14.5 0 mm.
3.6 DROOP OPERATION
Droop operation is obtained by setting the droop potentiometer. Clockwise increases the droop. The amount of droop for
a given setting depends on the magnetic pickup frequency
and no load to full load actuator shaft rotation. A droop
potentiometer setting of 10 o'clock will give about 4% droop,
no load to full load when the pickup frequency is 4260 Hz and
actuator shaft rotation is approximately 30 degrees from no
load to full load. Lower pickup frequency or smaller shaft
rotation results in less droop for the system.

4.1.3.1 Remove the inspection cover over the ring gear teeth.
The teeth should be free of burrs, excessive grease or dirt.
4.1.3.2 The magnetic pickup should not be installed in inspection covers. Inspect the ring gear housing and pick a location
where a 37/64" hole can be drilled such that the ring gear teeth
will pass in front of the pickup pole face. After the 37/64" hole
is drilled, use a 5/8-18 starting tap to cut threads for the
magnetic pickup, then run a bottom tap through the hole.
NOTE
The tapped hole should be drilled as nearly perpendicular
as possible over the center of the ring gear teeth.
4.1.3.3 Manually rotate the ring gear until a tooth face is directly
in the center of the tapped hole. Gently turn the magnetic pickup
clockwise into the hole until it bottoms on the tooth, and back off
1/4 turn. Tighten the jam nut firmly, maintaining the 1/4 turn
position.

NOTE
5.2.5 Start the engine.
5.2.5.1 Adjust the controller speed potentiometer until the
engine is operating at the desired engine RPM. Clockwise
increases engine RPM.
5.2.5.2 If the governor system is unstable, slightly reduce the
GAIN setting.
NOTE
Except for the speed adjustment, the potentiometers
have internal stops at the 0 and 100% positions.
5.2.6 With the engine unloaded, finalize the settings, I and
GAIN adjustments as follows:
5.2.3 Initial potentiometer settings:
5.2.3.1 Set the I adjustment three divisions from zero and
the GAIN at the second division from zero.
5.2.3.2 For isochronous operation, set DROOP counterclockwise to minimum position as shown in paragraphs 3.5
and 3.6.
5.2.3.3 For DROOP operation, set DROOP potentiometer
clockwise to obtain desired amount of DROOP from no-load to
full load. Turning potentiometer clockwise increases DROOP.
NOTE
If the full 35° rotation of the actuator shaft is used and
the linkage adjusted to use only the active fuel range,
the maximum obtainable DROOP would be approximately 12% at full load.
5.3.3.4 See step 5.3 for setting switches S1 and S2.
5.2.4 If a remote speed potentiometer is used for narrow
range, set it to mid-range. If the remote speed potentiometer is
connected to terminals 6, 7 and 9, a resistor "R" in the wiper is
not needed. This will provide approximately a ±5% adjustable
speed range.
5.2.6.1 Turn the GAIN adjustment clockwise slowly until the
actuator lever oscillates. (One may need to disturb actuator
lever to cause oscillation.) Reduce the GAIN adjustment slowly
counterclockwise until the lever is stable. Upset the lever by
hand. If the lever oscillates 3 to 5 diminishing oscillations and
stops, the setting is correct.
If system performance to load changes is satisfactory, omit step
5.2.6.2.
5.2.6.2 Reduce the GAIN setting counterclockwise one division. Next, turn the I adjustment fully clockwise while observing
the actuator lever. If the lever does not become unstable, upset
it by hand. When the lever slowly oscillates, turn the adjustment
counterclockwise slowly until the lever is stable. Upset the lever
again; it should oscillate 3 to 5 times and then become stable
for optimum response.
NOTE
Use the settings of step 5.2.6.1 or step 5.2.6.2,
whichever provides the best performance.
5.2.6.3 Unit is now calibrated.

applications.
5.3.2 Two actuator selections, so the same controller can be
used on the DYNA 8000, DYNA 8200 or DYNA 8400 actuator.*
• Set S2 to the OFF position when using a DYNA 8000
actuator.
• Set S2 to the ON position when using a DYNA 8200 or DYNA
8400 actuator.
5.4. GENERAL INFORMATION ON S1 AND S2
• Switch S1 selects one of two integrating rate ranges. The
diesel version integrates at twice the rate of the gas version
• Switch S2 selects the point at which actuator coil current
level causes the integrator limit to be actuated. This level
is nominally 6.3 amperes for the DYNA 8000 and 7.3 amperes for the DYNA 8200 and 8400 actuator.
Question: How do I know if the switches in the dual-in-line
packages are correctly set as far as being in the OFF position
or the ON position?

Answer: The drawings above should clarify any confusion
about switch settings. The easiest way to set the switches is to
apply pressure with a small pointed object until the switch clicks
into position.
CAUTION
As a safety measure, the engine should be equipped with
an independent overspeed shutdown device in the event
of failure which may render the governor inoperative.
* DYNA 8000 -- DYNC 11020 Series
DYNA 8200 -- DYNC 12000 Series
DYNA 8400 -- DYNC 14800 Series
These actuators do not have a potentiometer feedback
transducer.
NOTE
For some diesel engines, better operation may be
obtained by placing SW1 in "ON" position. If
difficulty is experienced in "OFF" position, try SW1
ON and recalibrate.

NOTE
6.3.5 After calibration, it may be necessary to readjust the
speed.
6.3.6 Following the above calibration, conduct the following
test. With the engine operating at rated speed, turn the electric
governor off. When engine speed slows to approximately half
of rated speed, turn the electric governor back on. Observe the
overshoot. If there is a small hunt at steady state, slightly turn
the "I" potentiometer counterclockwise until stable. In some
cases, 2 to 3 Hz overshoot may be acceptable.
WARNING
For gas engines, make certain that method used
does not put gas in exhaust which might result in
an explosion.
If possible, operate the unit through various load ranges up to
100% to ensure stability.
6.4 CONTROLLERS HAVE SWITCHES S1 AND S2
These units have two new features now added to the DYN1
1068X series controllers. They are:
6.4.1 Two response ranges for matching either the diesel or
gas engine dynamics.
6.3 START ENGINE (NO LOAD)
6.3.1 Adjust the controller speed potentiometer for desired
engine speed.
6.3.2 Adjust the GAIN potentiometer clockwise until the en-
gine begins to hunt. (If the engine remains stable at 100%
GAIN, physically disrupt the actuator linkage by hand.) With
the engine hunting, turn the GAIN potentiometer counterclockwise until stable.
6.3.3 Repeat step 6.3.2 for the "D" setting.
6.3.4 Repeat step 6.3.2 for the "I" setting.
• Set S1 to the OFF position for diesel engine applications.
• Set S1 to the ON position for gas/gasoline engine
applications.
6.4.2 Two actuator selections, so the same controller can be
used on the DYNA 8000, DYNA 8200 or DYNA 8400 actuator.*
• Set S2 to the OFF position when using a DYNA 8000
actuator.
• Set S2 to the ON position when using a DYNA 8200 or DYNA
8400 actuator.

6.5 GENERAL INFORMATION ON S1 AND S2
• Switch S1 selects one of two integrating rate ranges. The
diesel version integrates at twice the rate of the gas version.
• Switch S2 selects the point at which actuator coil current
level causes the integrator limit to be actuated. This level is
nominally 6.3 amperes for the DYNA 8000 and 7.3 amperes
for the DYNA 8200 and 8400 actuator.

Answer: The drawings above should clarify any confusion
about switch settings. The easiest way to set the switches is to
apply pressure with a small pointed object until the switch
clicks into position.
* DYNA 8000 -- DYNC 11020 Series
DYNA 8200 -- DYNC 12000 Series
DYNA 8400 -- DYNC 14800 Series
These actuators do not have a potentiometer feedback
transducer.
NOTE
A warm engine is normally more stable than a cold one. If the
governor is adjusted on a warm engine, turn the adjustment
potentiometers counterclockwise 5% (1/2 div.) to ensure a
stable engine when started cold.
CAUTION
As a safety measure, the engine should be equipped with an
independent overspeed shutdown device in the event of failure
which may render the governor inoperative.

7. DYNA 8000 SERIES TROUBLESHOOTING CHART
7.1 PROBLEM: GOVERNOR IS COMPLETELY DEAD AND ACTUATOR LEVER STAYS AT MINIMUM POSITION
WHEN POWER IS APPLIED TO GOVERNOR.
Means of Detection
7.1.1 Check battery voltage at terminals 1 and 2 on
controller. Terminal 1 is positive.
7.1.2 Check for proper linkage setup.
7.1.3 Magnetic pickup signal absent or too low.
Measure AC voltage across terminals 10 and 11
while cranking the engine. Voltage should be
min. 2.5 VAC. Note: The voltmeter should have
an impedance of 5000 ohms/volts or higher.
7.1.4 Measure the resistance of the magnetic pickup
coil. This should be above 150 ohms.
7.1.5 Measure the resistance of each pin to the metal
case of the magnetic pickup. No continuity
should be evident.
7.1.6 DC SUPPLY OFF. Place an insulated jumper
between terminals 2 and 3 (TP1 & TP2). With DC
ON, the actuator should go to full stroke. DC
voltage at terminals 4 and 5 should be within 3
volts of the supply.
7.1.7 Measure actuator coil resistance:
Corrective Action
Check battery connections and contacts for turning power
ON to the controller.
Correct and free linkage.
Check pole tip gap over gear tooth. Should be
.037 mm ±0.127 mm (0.015" ±0.005").
If there is an open or shorted coil, replace the magnetic
pickup.
If there is continuity to case, replace the magnetic pickup.
If the actuator still does not move to full stroke, continue
with steps below.
If actuator coil is open or shorted to case, replace actuator.
DYNA 8000
12 VDC unit. Coil resistance 0.75 ±0.2 ohms.
24 VDC unit. Coil resistance 2.3 ±0.4 ohms.
DYNA 8200
12 VDC unit. Coil resistance .710 ±0.2 ohms.
24 VDC unit. Coil resistance 1.600 ±0.4 ohms.
DYNA 8400
24 VDC unit. Coil resistance 1.630 ±0.4 ohms.
7.1.8 Measuring the resistance of each coil lead to
the actuator case should indicate an open circuit
on a low scale of the ohm meter.
7.1.9 With the DC to the governor ON and the engine
OFF, measure the DC voltage from terminal 6 (+)
to terminal 2 (-). This should be approx. 8 VDC.
7.1.10 Between terminal 7 (+) to terminal 2 (-), the
voltage should be approx. 4 VDC.
If governor still does not operate, continue with steps below.
If continuity is detected, replace the actuator.
If 8 VDC is not present, replace the controller.
If 4 VDC is not present, replace the controller.
