Lifting Arms 215
• If the gripper does not close while raising the arm, the limit switch is not properly adjusted.
In that case, completely lower the gripper and adjust the limit switch so that it clicks as soon as
the target is detected.
6. Perform a few up-and-down cycles of the gripper.
Each time on its way up to the top, the gripper should close automatically in order not to hit the
vehicle.
IMPORTANT: If the system does not work properly, it may be necessary to replace the limit switch.
Auto-Packing
The Auto-Packing switch (see Figure 10-10) enables the packer to automatically start cycling about
2 seconds after the gripper reached the mid-height position on its way up. If the packer is performing
a cycle while the lifting arm carries a rolling cart towards the hopper, the packer will immediately stop
and return to its home position, no matter where it was in the hopper. This is to prevent refuse from
falling directly on the packer. However, there is one exception to this: if, after 3 consecutive packing
cycles, the packer fully extend proximity switch has not been activated, the packer will not return to its
home position.
Figure 10-10
Auto-Packing switch
NOTE: For co-mingle units, the packer does not automatically return to its home position during
auto-packing because the hopper is too small due to the presence of a chute inside the hopper.
When the Auto-Packing feature is used simultaneously with the Multi-Cycle feature, the packer will
then perform a preset number of cycles unless a new rolling cart is carried towards the hopper by the
automated arm. In such a case, the Multi-Cycle feature will then be reset to zero.
When a packing cycle has been interrupted and the packer has returned to its home position, a new
cycle will begin 2 seconds after the gripper reached the mid-height position on its way up.
