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
recommended.
• If the EEG7000 controller detects no input from the magnetic pickup, the controller sets the actuator to 0 V DC and the speed to
0 rpm. If the controller detects loss of magnetic pickup, LED 2 turns solid red and the system must be reset.
• To reset the EEG7000, 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 [0.5 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.
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
AUX input from Pin 4 is activated by selecting Auxiliary Enable in the GACong Tool Advanced Conguration menu and selecting the
desired Aux / Load Sharing pane.
The AUX function decreases engine speed with increasing input voltage, the polarity shift function increases engine speed with in-
creasing input voltage. AUX input is nominally 5.0 V +/- 5.0 V DC. The GACong Tool Aux/Load Sharing allows you to set polarity as
decreasing or increasing speed.
Pins 1 and 2 are dedicated to actuator usage. Polarity is not required. See your specic actuator manual for details.

The EEG7000 has two inputs, which in various combinations, allow the user to use three xed speed settings or the variable speed
setting. 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 from the Engine Tuning menu in
the Fixed Speed and Variable Speed panes.
• To set variable speed, update to the desired rpm. See Section 10,
Setting Variable Speed Parameters for more details.
• Automatically calibrate Input Minimum and Input Maximum settings
related to the variable speed potentiometer or other related control
using Calibrate Minimum or Calibrate Maximum.
• To calibrate the minimum percent set the potentiometer to the
desired start value and click 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. Connect a 5 kΩ potentiometer between Pins 7, 9 and
12 as shown in 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. Speed switch output (SSW) can provide overspeed protection, starter cutoff (crank termination), and other general aux-
iliary 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 SSW is cycled. When the box is not checked
the output state automatically resets at 0 rpm. The default is checked (ON).

Setting variable speed requires a potentiometer, available from GAC.
A potentiometer calibration within the GACong Tool characterizes the
selected potentiometer.
Analog variable speed is enabled when Pins 5 and 6 are not grounded.
To add a potentiometer:
1. Connect either a 5 kΩ potentiometer, 0 - 5 V DC or 4 - 20 mA
speed input signal to Pin 9.
2. Set the Variable Speed Input Mode in the GACong Tool to 0 - 5 V
DC or 4 - 20 mA.
3. To calibrate the potentiometer:
a. Open Engine Tuning  Variable Speed.
b. Set the potentiometer to the full CCW position and click
Calibrate Minimum.
c. Turn the potentiometer CW all the way and click Calibrate
Maximum.
d. Note the Input Actual result
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.
