EEG7000 BASIC WIRING

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 GAConfig Tool Advanced Configuration 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 GAConfig 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 specific actuator manual for details.
