Heavy Duty Auto Throttle Applications

Utility and Maintenance Vehicles

Increases engine RPM to provide full current output of the alternator when using various types of DC

and AC tools and equipment.

The Auto Throttle is excellent for use with DC to AC inverters that operate electric drills, grinders,

exhaust fans and blowers, plastic pipe fusion equipment and engineering test equipment. (Vanner

can provide a complete electrical distributing system for utility vehicles using DC to AC inverters,

alternator power boosters, battery isolators, and auto throttles.)

Bucket and Boom Trucks - Power Take-Offs

In vehicles with on-board hydraulic systems, the Auto Throttle will increase engine RPM, allowing

equipment to operate at maximum efficiency and provide proper operating pressures. The Auto

Throttle can be activated by a hydraulic pressure switch, which turns it on when the hydraulic system

is engaged.

Emergency Vehicles

Particularly desirable in police cars, fire trucks, ambulances, and other emergency equipment when

current exceeds alternator output at idle resulting from operating emergency rotating beacons,

flashing warning lights, DC to AC inverters and other electrical equipment.

The Vanner Auto Throttle is activated by an on/off switch (or through the master module disconnect

switch on ambulances as mandated by KKK-A-1822D specifications). The Auto Throttle releases the

high engine idle instantly when the shift lever is moved to any drive position or when the brake

pedal is depressed to prevent the vehicle from surging. It reactivates when the gear shift lever is

placed into park or neutral and when the foot brake pedal is released.

Heavy Duty Automatic Throttle System

Vanner’s Heavy Duty Auto Throttle features a strong solenoid that can control the RPM’s of the toughest

diesel engine, under the most extreme environmental conditions. The twenty pound pull power of the Auto

Throttle provides positive and constant RPM engine control. A key design feature incorporating a vernier

control allowing one-hand, precise adjustment has been built into the Model 73-46. This design feature

ensures that the most critical adjustment can be made with ease and accuracy.

AutoThrottle Manual Vanner Power Group Section 2 — Theory of Operation The solenoid of the 73-46 is a continuous duty, 12-volt utilizing internal dual coils. The first, a pull-in coil, is designed for 12-volt intermittent duty (increasing engine RPM to high idle); while the second; a hold-in coil is designed for continuous duty (maintaining high idle engine RPM). The solenoid plunger is activated by the pull-in coil and bottoms in the solenoid instantly, then is held in this position by the hold-in coil.

Vanner Power Group AutoThrottle Manual 0.5 to 1.0 amp reading. If the plunger does not pull in, and you see a 0.5 10 1.0 am reading, the solenoid is not functioning correctly and must be replaced. If the plunger does pull in and bottoms out, but your amp reading is outside the above ranges, the solenoid is not functioning properly and must be replaced. This completes the electrical test of the solenoid.

With the engine off, lock the cable endbell (1) to the mounting bracket to prevent the cable housing from turning during adjustment. 2. Insert cable through ring terminal; do not crimp terminal eye, allowing cable to move freely. 3. Release the hex locknut (2). Turn the brass cable adjuster (3) counterclockwise until it is fully inserted in the actuator. 4.

A bridge rectifier (Radio Shack #276-1185 or Westinghouse MB12A25V05) can be used in place of the blocking diode. NOTE 2: The Vanner Model 73-46 Auto Throttle incorporates a dual coil solenoid.
