3-8. Side Belt Inner Limit
This is not a routine adjustment. Normally, it is
necessary only after major disassembly or repair of
related components.
Specification
With no box in the case sealer, adjust the side drive
belt assembly inner limit reed switch so that the
assembly closes to the center of the case sealer bed.
All side drive belt motors stop and the assembly
returns to its outermost position.
Adjustment
1. Raise the upper head assembly to its uppermost
position by setting the mode selector switch to
RANDOM and pressing the RESET button.
2. Turn off the main air valve and the electrical
disconnect switch.
3. Refer to Section 4-6, Case Sealer Bed Plates, and
remove the center roller assembly.
4. Turn on the main air valve and the electrical
disconnect switch. Press the RESET button then
the START
5. Block the light path from PC1 and then PC3.
Blocking the light path of PC3 causes the side
drive belt assembly to move in to the center. This
closes the limit reed switch on the assembly
movement cylinder. The switch closing initiates
an input to the Programmable Controller result-
ing in a fault condition, which causes the assem-
bly to return to its outermost position.
6. If the side drive belt assembly does not move to
its outermost position, press the STOP button.
The assembly will move out so the following
adjustment can be made.
7. Refer to Figure 3-7. Using a 2 mm hex wrench
loosen the screws on the reed switch. Move the
switch to the right in increments until, when
tested as described earlier, the assembly returns
to its outermost position.
8. Replace the center roller assembly.
