    • 2.6 Cylinder/Platform Installation
      • 1. Fit the pivoting intermediate frame over the hinge pins (Figure 2-2, B). The intermediate frame should be seated on the pit coping corner plates (Figure 2-2, C).
      • 2. Attach the rod end of each cylinder to the intermediate frame support tube. The cylinder muffler should face upward toward the scale.
      • 3. Adjust each cylinder rod until it is approximately 1" from the fully-retracted position (Figure 2-2, D). Place the pivot brackets (Figure 2-2, E) against the pit floor and use them as templates to mark the mounting hole locations. Be sure the air ...
      • 4. Drill holes, install anchors, and secure the cylinder pivot brackets to the pit floor.
      • 5. Attach the main air line to the inlet side of the regulator (Figure 2-2, F). Attach the air line from the outlet side of the regulator to the input fitting on the pneumatic control box (Figure 2-2, G).
      • 6. Attach the air lines from the output fitting on the pneumatic control box to cylinders. Apply 85-100 psi air pressure to the cylinders. Check for air leaks.
      • 7. Place the platform scale onto the intermediate frame (Figure 2-2, H), making sure feet sit on corner pads without rocking. Adjust feet as necessary so the platform is level to within 1/4".
      • 8. Feed the load cell cables through the conduit. Leave a strain relief loop to allow enough cable for free movement of the scale in the lifted position without tension in the cables (Figure 2-2, J).
      • 9. Route the load cell cables through the fittings in the junction box (Figure 2-2, K). Wire the cables to the junction box according to the corner numbering diagram (Figure ) and load cell wiring chart (Table 2-3). Coil and store excess cable before...
      • 10. Adjust speed during the lift cycle using the up speed adjustment screw (Figure 2-2, L) in the pneumatic control box. Once you have achieved the desired speed, tighten the lock nut. Adjust descent speed using the down speed adjustment screw (Figur...
