GAC’s EEG7000 electronic digital speed controller is designed to regulate engine speed on
diesel and gaseous fueled engines. When paired with a GAC actuator the EEG7000 is a suit-
able upgrade for any mechanical governor system that needs exibility, precision, and accurate
control of governed speed.
The EEG7000 is designed for industrial engine applications including generator sets, me-
chanical drives, pumps, compressors and off-road mobile equipment. The GACong Tool
adds the ability to monitor and set parameters from your PC. With CAN J1939 capability it
has the ability to accept TSC1 messages over USB as a mini engine control module (ECM).
It can be controlled directly over J1939 with aftermarket displays such as ComAp, Dynagen,
and Murphy – a solution for every application.

An overspeed shutdown device, independent of the governor system, should be used to prevent loss
of engine control which may cause personal injury or equipment damage.
Do not rely exclusively on the governor system electric actuator to prevent overspeed. A secondary

PIN 3 - MAGNETIC SPEED PICK-UP
A magnetic speed sensor detects when ring gear teeth pass the tip of the magnetic speed sensor. The output signal is an AC sine wave
whose frequency is converted to crankshaft revolutions per minute (RPM). The following are required:
A magnetic pickup must be installed in the engine bell housing, ring gear case, or fabricated bracket.
All wires must be twisted and/or shielded for their entire length (14 turns per foot).
Ground shield to case. Do not tie case to ground.
The magnetic speed sensor voltage should be at least 1 V RMS while cranking. During operation, 5 to10 V RMS is recommend-
ed.
If the EEG7000 detects no input from the magnetic pickup, the EEG sets the actuator to 0 V DC and the speed to 0 RPM. If the
EEG detects loss of magnetic pickup, LED 2 turns solid red and the system must be reset.
To reset the EEG, cycle DC power.
The magnetic speed sensor connections MUST BE TWISTED AND/OR SHIELDED for their entire length.
The speed sensor cable shield must only be connected to the case. The shield should be insulated to ensure that no other part
of it comes into contact with engine ground, otherwise stray signals may be introduced into the speed switch.
Minimum gap between speed sensor and gear teeth is 0.02 in [.5 mm]. When the engine is stopped, adjust the gap between the
magnetic speed sensor and the ring gear teeth. Usually, backing out the speed sensor 3/4 turn after touching the ring gear tooth
will result in a satisfactory gap.
EEG7000
Aux accepts signals from:
GAC accessories
Auto synchronizers
Load sharing units
Other governing accessories
The auxiliary (AUX) pin accepts input signals from load sharing units, auto synchronizers, and other governor system accessories. The
AUXILIARY input from Pin 4 is activated by selecting Auxiliary Enable in the GACong Tool Advanced Governor Settings menu and
selecting the desired Auxiliary Polarity.
The AUX function decreases engine speed with increasing input voltage, the polarity shift function increases engine speed with increas-
ing input voltage. Aux input is nominally 5.0 V +/- 5.0 V DC.

PINS 5 AND 6 - SPEED SELECT
The EEG7000 has two inputs which, in various combinations, allow the user to use three xed speed settings or the variable speed set-
ting. This is accomplished by tying inputs to ground or leaving them open. Fixed Speed 1 can be set to idle as required.
Speed is set from the GACong Tool on the Engine Tuning menu in the
Fixed Speed and Variable Speed blocks.
To set variable speed, select the analog mode for your variable
input signal, and input desired RPM. See Section 10, Setting Vari-
able Speed Parameters bulletin for more details.
The Analog 1 minimum and maximum settings can be
automatically calibrated using Calibrate Minimum or Calibrate
Maximum.
To calibrate the minimum percent set the potentiometer to the
desired start value and click the Calibrate Minimum button. To
calibrate the maximum percent set the potentiometer to the
highest end value and click Calibrate Maximum button. The
difference between the analog minimum speed settings will be at
least 25 % to prevent rough idle.

Pin 7 provides analog input from external trim or variable speed potentiometers. It is also used to create resistive Input: (Select 0 - 5V
/ Resistive). Connect a 5 k Ω potentiometer between Pins 7, 9 and 12 as shown under Variable Speed.
PIN 7 - ANALOG INPUT
When the EEG7000 detects engine speed has reached the user dened Limit / Threshold value, the EEG7000 controller changes the
state of Pin 8. The SSW can be used for overspeed protection, starter cutoff (crank termination), and other general auxiliary functions.
The SSW adjustment range is 100 to 6000 RPM. The default value is 1800 RPM and the default state (Mode) is NORMALLY
OPEN.
When NORMALLY OPEN is selected the SSW output on Pin 8 will energize at the set speed. When NORMALLY CLOSED is
selected output from Pin 8 will de-energize at the speed setting.
When the LATCHING box is checked the SSW output state is xed until power to the unit is cycled. When the box is not checked
the output state automatically resets at 0 RPM. The default is checked (ON).

Analog variable speed is enabled when Pins 5 and 6 are not grounded.
Connect a 5 kΩ potentiometer,0 - 5 V DC or 4 - 20 mA speed input signal,to
Pin 9. The default setting is 0 - 5 V DC with variable speed available.
Variable Speed Analog 1 Mode in the GACong Tool must be set to 0-5 V
DC or 4-20 mA to use this function.
Setting variable speed requires a potentiometer, available from GAC. A
potentiometer calibration within the GACong Tool characterizes the
selected potentiometer.
Variable Speed can be used as another xed speed setting if both Speed
Minimum and Speed Maximum parameters are set to the same RPM and
no potentiometer is connected.
For more details on setting variable speed see Section 10, Setting Variable
Speed Parameters.
PIN 9 - ANALOG VARIABLE SPEED
Setting the Minimum Speed and Maximum Speed to the same
value with no input on Pin 9 enables you to use Variable Speed
as an additional xed speed setting.
The CAN bus must be terminated at both ends by a 120Ω resistor.
Use cable harness CH1520, 7 AWG, or EC1502 mating connector
kit with twisted pair that meets SAE J1939 or SAE J1128 stan-
dards.
PINS 13 AND 14 - CAN H AND CAN L - RS-232

Wiring between the engine, the EEG7000 speed unit, and the actuator should be completed before starting the engine. See Sections
5 and 6 for more wiring details. The following are the minimum wiring requirements:
Connect Actuator to EEG7000 (Pins A and B)
Connect Actuator to magnetic pickups (Pins 1 and 2)
Connect EEG7000 to battery (Pins C and D)
Connect USB from EEG7000 to PC
The EEG7000 can be set up and used straight out of the box, with an actuator attached, using default settings. This section details
the initial installation and setup using the default settings. Wiring between the engine and the EEG7000 is required, and reviewing this
document and default settings is advised.
There are two sets of parameters to work with: basic engine performance and engine tuning. Getting Started gets your engine started.
Engine Tuning improves performance.
Before you start your engine:
Install the GACong Tool on a PC and connect the PC to the EEG7000 with the USB cable
Provide power to the EEG from the battery.
Install an actuator between EEG7000 and engine, following your actuators Installation Manual.
Set the following minimum settings in the GACong Tool on the Engine Tuning menu:
• Overspeed for automatic actuator shutdown
• Number of engine ywheel teeth
• Fuel Limit
• Acceleration and Deceleration
• Actuator Ramp Rate
• Starter Cutoff
• Fixed Speed Settings
Once the parameter settings are reviewed and values updated as required, reconnect your fuel supply and start your engine.
1. Reconnect the fuel supply.
2. Crank the engine with DC power applied to the governor system. The engine should be at operating speed with no load.
3. The actuator/ fuel to the engine will be positioned to the level set by the Actuator Start Fuel (default is maximum fuel). Actuator Ramp
Rate controls the rate at which fuel is increased to start the engine, 10% by default.
4. If the engine is unstable after starting, open the GACong Tool and adjust the Gain, Stability, and Deadtime in the Engine Tuning menu
in the PID Tuning block, until the engine is relatively stable.
5. Once the engine is stable you can connect additional devices and further tune your engine.
Do not rely exclusively on the governor system electronic actuator to prevent overspeed. A secondary shutoff
device, such as a fuel solenoid must be used. STOP ENGINE shuts down the actuator, not the engine.
