    QUICK REFERENCE INSTALLATION INFORMATION Pneumatic Requirements: (One Hookup) Run 1/2" line to main Filter / Regulator with an output of 4 CFM operating at 80 PSI. Electrical Requirements: (One Hookup) A 25 amp dedicated circuit should be supplied to the main control panel.

  • Page 5: Warnings And Notices

    WARNINGS AND NOTICES WARNING The purpose of this section is to alert operating and maintenance personnel to the possible dangers of this type of equipment. Serious injury and/or equipment damage could result from not heeding these safety precautions. BEFORE OPERATING EQUIPMENT: Any personnel working directly with or on this equipment should read this manual before proceeding with equipment use.

  • Page 6: Grounding Recommendations And Noise

    If additional wire runs are added to any junction box or control panel, wiring practice should be such as to maintain prevailing electrical hazard classification. High-pressure air systems are dangerous. Do not service or troubleshoot systems with air supply on. Be sure to bleed off any trapped air before working on components since it is possible to have high pressures trapped in airlines and cylinders, etc.
  • Page 7 (such as copper lugs). Minimum wire sizes, color coding, and general safety practices should comply with American National Standards and the National Electrical Code. Other earth ground sources are not as desirable as a copper ground stake. Green wire earth grounds (safety grounds) brought into the control system from plants distribution networks tend to be very noisy.
  • Page 8 EFFECTS OF ELECTRICAL NOISE The predominant effect of noise on the system is to cause “soft” failures; that is, failures which do not damage the system but do cause it to function improperly. Three main types of soft failures are encountered: 1.

    9. Keep fingers, hands, feet, clothing, etc., out of the path of pneumatically operated components. 10 Safety glasses should be worn in equipment area. 11. Follow the safety regulations for your plant. ALWAYS USE GOOD JUDGEMENT. SPECIFIC REQUIREMENTS 1. Voltage The system is designed for one location hookup.

  • Page 13: Dust Collection

    DUST COLLECTION A 4” dust hookup is located on the upper filler pipe. This pipe should be connected to dust collection piping with a damper so the amount of volume of air can be adjusted to the fill head. If you have too much draw, material will be drawn up from the stream along with the dust during the filling cycle.

    CONNECTING TO SUPPLY BIN The Model 520 Bulk Bag Filler can be fed via slide-gate valve, butterfly valve, auger, rotary vane feeder or air lock feeder. In a typical installation, one of these feed devices will be fastened directly to the customers supply bin. An 8" flex connector hose is installed to the outlet side of the chosen feed device down to the bulk bag filler head.

    SETTING CONVEYORS Once the BB is in place and anchored, use a chalk line to layout any conveyors to the system. Refer back to layout drawing to set remaining conveyors. If the BBL is equipped with a powered conveyor, this will come secured to the BBL structure. Layout a line parallel line to the powered discharge conveyor, maintaining a 1/2"...

    configurations of how the densifier system can be set up. They can be run intermittently, continuously or after weight complete.  Once the target weight is achieved, a signal is sent to close / stop the overhead feed device.  The controller will take a final reading, adjust for weight variations.

  • Page 30: Bag Seal Cuff (Optional)

    BAG SEAL CUFF (OPTIONAL) The bag seal cuff is a feature that prevents dust from coming out of the bulk bag during the filling process. A. Bag Cuff Inflate Switch The operator presses the blue PB to inflate and bag seal cuff. Check the pressure on the regulator, to make sure the pressure is between 3-5 PSI to start.

  • Page 31: Pre-Bag Inflate (Optional)

    CAUTION: should be exercised when inflating the cuff. Over-inflation could cause the seal to burst causing injury to the operator, and or the fill sleeve of the bulk bag. NOTICE: Eye and ear protection may be required when operating this equipment.
