TR-3 INVERSION VALVE - installed in the foot valve service
delivery line and exhausts air from the air cylinder each time a
service brake application is made. This serves as a pneumatic
back-up disengagement system and assures that no single
point failure. either electrical or pneumatic. will allow the engine
to overspeed after a brake application is made.
THROTTLE CABLE ASSEMBLY - links the air cylinder to the
engine throttle control. It permits the pull developed by the air
cylinder to be transmitted to the engine throttle. The cable
incorporates a threaded nut for attachment to the air cylinder.
See figure 9-12.

within easy reach of the driver. are used to control the system
{figure 9-13}. The On/Off switch supplies electrical power to
