AIR THROTTLE/ELECTRONIC RETARD
CONTROL
Trucks equipped with an air throttle use an air pressure modulating treadle valve to control an air cylinder attached to the engine fuel control device. (Refer to Section K for throttle treadle service information.)
The AS switch described below provides the propulsion initiation signal (AS) to the FL275 panel when the accelerator pedal is depressed.
If equipped with an air operated throttle, the truck will utilize an operator controlled, electronic retard initiation and modulation control system consisting of an electronic retard pedal and a Retard Panel [RET] (5, Figure 2-32) providing FL275 panel interface requirements.
The Retard Panel receives a variable voltage signal from the foot pedal, proportional to the angle of depression of the pedal. The RET panel provides a signal (RS) to initiate retarding and a variable voltage signal (RPINHI) proportional to the amount of retarding
effort, requested by the operator, to the FL275 panel.
For retard pedal service, refer to ”Electronic Accelerator And Retard Pedals” in this Section. For RET service and adjustment, refer to “Statex III Electrical Checkout Procedure”, Section 1.2.
