General information, wiring and calibration procedure for the DYN1-10704, 10714, 10724 and
10734 controllers for the linear governor system.
CALIBRATION
1. With no power to the governor, adjust the GAIN to
9:00 o’clock.
2. Start the engine and adjust the speed by turning
the SPEED pot clockwise to desired speed.
NOTE
Controllers are factory adjusted to mini-
mumRPM. However,forsafety,oneshould
be capable of disabling the engine if an
overspeed should exist.
3. At no load, turn the GAIN potentiometer clockwise
until the engine begins to hunt. If the engine does
not hunt, physically upset the governor linkage.
4. Turn the GAIN potentiometer counterclockwise
until stable.
WIRING
All four non controllers are wired as shown in
Figure 1 Wiring Diagram.
1. Red to battery positive.
2. Black to battery negative.
3. Purple to the actuator, no polarity.
4. White to one side of the magnetic pickup.
5. Black and white to the other side of the magnetic
pickup connected with the shield drain wire.

Note: The shield on the MPU is to be connected to
the black wire along with one of the MPU
conductors.

I. System appears dead. (Actuator fails to
move to full fuel) Check connections to battery.
Note: Turn off power and reconnect Purple lead.
III. Actuator hunts during operation.
Note: Reconnect actuator leads properly after
completing this test.
II. Actuator lever goes to full fuel whenever
the power is turned "ON" and engine is
not running.
1. CHECK CONTROLLER by removing actuator lead to
Purple lead and turning power “ON” to controller.
a. Actuator goes to full fuel.
b. Actuator does not go to full fuel.
1. CHECK BATTERY VOLTAGE AT CONTROLLER
with power switch “ON”. Measure DC battery voltage
between the Red (+) and Black (-) leads. Battery
voltage should be present.
2. CHECK LINKAGE. Manually operate linkage to see
that it is not sticking or binding.
3. NO SIGNAL OR WEAK SIGNAL FROM MAGNETIC
PICKUP. Measure AC voltage between the White and
Black/White leads on controller while cranking engine.
Voltage should be 2.5 volts RMS or greater. (AC input
impedance of meter must be 5000 ohms/volt or greater.)
4. CHECK ACTUATOR with power “ON” to controller.
Measure following terminals on control box with respect
to the Black lead. All points should read BATTERY
VOLTAGE. (+0.00/-0.75 VDC)
a. Purple lead to Black lead on controller.
b. Second Purple lead to Black lead on controller.
(Continue this test only if battery voltage is not
present.)
c. Following checks are terminals on the actuator
and the Black lead on controller.
1) Low voltage (1.0-2.0 VDC) at either
actuator connector.
2) Battery voltage at both actuator connectors.
3) Battery voltage at one actuator lead but not
at the other.
Check for damage to or improper
adjustment of magnetic pickup.
Replace or re-adjust.
Free linkage.
Replace controller if battery voltage
is not present at both Purple leads.
Broken actuator lead.
Replace actuator.
Broken actuator lead.
1. Linkage or rod end bearings sticking or binding.
2. Improper linkage arrangement.
(Stroke too short or improper non-linear linkage used)
3. Improper governor adjustment.
4. Inadequate power supply voltage.
a. Turn power switch "OFF".
b. Connect a DC voltmeter to Red and Black leads
at control box.
c. Disconnect both leads to actuator at Purple
leads of control box.
d. Connect one actuator lead to the Red lead and
one actuator lead to the Black lead of the
control box.
e. Momentarily turn "ON" the DC power. The
actuator should go to full fuel and the DC
voltage must be greater than 80% of supply.
24 VDC @ 80% = 19.2 VDC
12 VDC @ 80% = 9.6 VDC
Check for shorted actuator lead.
Replace Controller because it should not
cause actuator lever to go to full fuel with
engine not running.
Lubricate or replace.
Readjust calibration.
If actuator doesn’t get to full fuel, then
check actuator leads. If voltage is less
than specified, check for loose or poor
connections to battery, or get larger supply
leads or larger power supply.
See installation information.

As a safety measure, the engine should be equipped with an
independent overspeed shutdown device in the event o
f
failure which may render the governor inoperative.
