Repeat the procedure until both limit switches are properly adjusted.
Pendulum Proximity Switches
Both the pack and return proximity switches are mounted on a plate above the pendulum arm pivot at
the rear of the hopper bowl on the streetside of the vehicle. These proximity switches are protected by
a removable cover (see Figure 3-26).

Figure 3-26 Removable cover
The pack and return proximity switches are normally open. These switches control the AUTOPACK
cycle as follows:

The pack proximity switch is triggered by a tab mounted to the pendulum arm pivot. When the
pendulum travels to the rear of the hopper bowl, the tab ACTIVATES the proximity switch and
the contacts close. This SENDS a signal to the control module, which then sends a signal to the
pendulum to BEGIN the PACKING sweep.
Danger! All limit switches MUST be working at all times. Otherwise, the operator may not be aware
that the arm is not fully retracted or that the gripper is open or closed. This may cause
accidents, injuries and/or property damage.
