ATB Series Integral Throttle Body Actuators

Transcription

1 T Series Integral Throttle ody ctuators 1 INTROUTION The T Series integral throttle body electric actuators are designed to control the air or air/fuel mixture to a gas or gaseous-fueled engine. They are typically used to control an engine by working in tandem with a conventional fuel mixer. xamples of the installation locations are shown here: 2 NOMNLTUR SUIX INITION 1 4 High Temperature & Sealed 2 Mechanical Position indicator, Sealed (Only available with non-high-temp version, T2 units only) Naturally spirated ngines Turbocharged-Intercooled ngines eedback Position Sensor, Sealed T N Normal (omes with no eedback Position Sensor), Sealed T xamples: irfilter Intercooler PRT NO.

5 6 INSTLLTION The actuator is mounted rigidly between the engine s intake manifold and the gas mixer. The preferred mounting orientation for the T 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 T Series is designed to provide an exact fit to the various manifolds and mixers available. Section 5 OUTLIN RWINGS on the other side of this document shows proper sizing of the T to the engine for envelope concerns. The arrow on the side of the T represents the direction of flow. UTION Gaseous uel Shut-Off Valve, Independent of the Throttle ody ctuator, Should e Provided to Prevent Loss of ngine ontrol or Propagation of a Hazardous lammable ondition Which May ause Personal Injury or quipment amage. n overspeed shutdown device, independent of the governor WRNING system, should be provided to prevent loss of engine control, which may cause personal injury. 7 WIRING ll throttle body actuators are pre-wired for either 12 or 24 V 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 MI effects on the control system. or applications where MI is still a concern, shielded cable for the actuator is recommended.

Max opening (100%) at 65 is 3.8V. 8 THROTTL JUSTMNT Typically, the engine speed should be set by un-plugging the actuator power to the governor or by turning off the governor power once the engine is running and then setting the engine speed to the desired setting. n adjustable Idle Stop set screw (Min Throttle djustment) is provided to set a fixed fuel opening if desired. elow represents where to generally find the adjustment screws on each T model. or a more detailed view, see Section 8 for Min and Max Throttle djustment screw locations. MX THROTTL Idle Stop djustment 1. Using a 2.5mm Hex wrench, you must completely remove the first locking setscrew. This will give you access to the inner idle setscrew. 2. Using the same Hex wrench, turning the wrench clockwise will increase the fixed throttle opening. 3. djustment is compete once you have replaced the locking setscrew. pply Locite 518 or equivalent. The locking setscrew should only be tightened to snug plus 1/4 turn Max throttle Stop is preset to 65 degrees from factory. 9 TROULSHOOTING 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. 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.
