9. Walk the conveyor and listen for leaks. Most leaks are a result of the tube not being fully seated

in the fitting, and can be corrected by pushing the tubing together. If the tube end is damaged or

not cut square, the tube may have to be disconnected and trimmed back to fix the leak.

Turn off and lock out the air supply before attempting to disconnect any push fittings.

System E-stop events must remove and safely discharge air pressure from the

conveyor. The pneumatic system contains hazardous stored energy.

10. Conveyors with pneumatic takeup drives will have a second, independent regulator and lockable

dump valve assembly on the drive module.

a. See section 5.11.2 for details on setting the appropriate pressure in a pneumatic takeup

assembly.

5.10 Accessories

Attach any applicable accessories and connecting hardware (e.g. guiderail) to the mounted conveyor

section at this point.

Refer to the "Bastian Solutions Conveyor - Side Cover and Guiderail Installation

Manual" for more information on installing most accessories.

Belt tensioning procedures are different depending on whether the conveyor has a screw takeup or

pneumatic takeup, but belt tracking is performed the same in all cases.

1. Once the belt is installed and joined, and all return rollers and tracking rollers have been installed,

then the belt may be tensioned.

2. See Figure 20: Screw Takeup Drive Belt Routing, which is a duplicate of the same figure from

section 5.4.1 for easier reference.

3. Ensure the takeup jam nuts are loosened where both takeup screws turn freely.

4. Back off both sleeve jam nuts several inches away from the plastic spring sleeves.

5. Alternately turn the takeup screws clockwise to tighten the belt. It is important to turn both screws

the same amount to keep the takeup carriage square to the frame and prevent it from binding.

6. As the takeup carriage moves away from the drive pulley, the spring sleeves will move with it.

Periodically check and back off the sleeve jam nuts as needed to provide space for the sleeves to

move.

7. Once the belt starts getting tight, monitor the tension indicators on the takeup brackets for

appropriate tension.
