Note :
* If wire leads are longer than 3 meters (10 ft), a shielded cable should be used. Ground

ONE END ONLY
* The speed control unit is rugged enough to be placed in a control cabinet or engine
mounted enclosure with other dedicated control equipment. If water, mist, or condensa-
tion may come in contact with the controller, it should be mounted vertically. This will
allow the fluid to drain away from the speed control unit.
* E ely heat should be avoided.

Caution :
An overspeed shutdown device, independent of the governor system, should be provided
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 shutoff device, such as a fuel solenoid must be used.
(C) Wiring
Basic electrical connections are illustrated above. Actuator and battery connections to
Terminals A, B, E, and F should be #16 AWG (1.3 mm
increased wire size to minimize voltage drops.
The battery positive (+) input, Terminal F, should be fused for 15 amps as illustrated.
Magnetic speed sensor connections to Terminals C and D MUST BE TWISTED AND/OR
SHIELDED for their entire length. The speed sensor cable shield should only be connect-
ed to terminal D. The shield should be insulated to insure no other part of the shield
comes in contact with engine ground, otherwise stray speed signals may be introduced to
the speed control unit. With the engine stopped, adjust the gap between the magnetic
speed sensor and the ring gear teeth. The gap should not be any smaller than 0.020 in,
(0.45 mm). Usually, backing out the speed sensor 3/4 turn after touching the ring gear
tooth will achieve a satisfactory air gap. The magnetic speed sensor voltage should be at
least 1 VAC RMS during cranking.
