INSTALLATION
The actuator is mounted rigidly between the engine’s intake manifold and the gas mixer. The preferred mounting orientation for the ATB Series is with the throttle shaft parallel to the engine crank shaft. Normal vibration from the engine will not affect the operation of the actuator. The ATB Series is designed to provide an exact fit to the various manifolds and mixers available. Section 4 OUTLINE DRAWINGS on the other side of this document shows proper sizing of the ATB to the engine for envelope concerns. NOTE
Typically, the engine speed should be set by un-plugging the actuator power to the governor or by turning off the governor power once 21 the engine is running and then setting the engine speed to the desired setting. NOTE
An adjustable Idle Stop set screw (Min Throttle Adjustment) is provided to set FULL RADIUS a fixed fuel opening if desired. Below represents where to generally find the adjustment screws on each ATB model. For a more detailed view, see Section 8 for Min and Max Throttle Adjustment screw locations.
The arrow on the side of the ATB represents the direction of flow. 1.
An overspeed shutdown device, independent of the governor system, should be provided to prevent loss of engine control, which may cause personal injury.

WARNING
All throttle body actuators are pre-wired for either 12 or 24 VDC systems. Use the included wiring harness to connect the actuator to the speed control unit’s output terminals. Prior to connecting the actuator cable, twist it so that there is about one complete twist per inch along the entire length of the cable. This will substantially re-duce EMI effects on the control system. For applications where EMI is still a concern, shielded cable for the actuator is recommended.
E
Using the same Hex wrench, turning the wrench clockwise will increase the fixed throttle opening. Ajustment is compete once you have repaced the locking setscrew. Apply Locite 518 or equivalent. The 2X locking setscrew should only be thightened to snug plus 1/4 turn FULL RADIUS Max throttle Stop is preset toFULL 65RADIUS degrees from factory.

Make sure to reconnect the actuator cable. Next, energize the actuator to full fuel (follow steps in the speed control publication). The throttle plate should move fully open. Next, rotate the throttle plate to determine if the plate moves smoothly without binding or sticking.

TROUBLESHOOTING
If the governor system fails to operate, the following test can be performed. Shut engine down, disconnect the actuator cable and measure the resistance at the actuator connector. Next, check resistance from each wire to the actuator housing and compare readings to values shown in Table 1. If the resistance values differ from values shown, the actuator is defective. This test is only to ensure that there is no obstruction, wire breakage or metal-on-metal contact inside the throttle body.
