Problem | Possible Cause & Solution |
Scale is Inoperative: (Applies to 6128 Scale) |
Air or electrical supply not connected. Solution: Check pneumatic and electrical connections to the scale. Controller circuits are locked. Solution: Push E-Stop/Abort switch to reset circuits, then pull out on the switch to run the scale. Fuse FU1 in the controller box is blown. Solution: Check for blown fuse and replace. Battery on the controller power supply/display card is dead (Models manufactured before 1998 only.**) Solution: Replace the battery with an equivalent 3.0V lithium battery. (See scale manual for more detailed instruction on battery replacement. |
Scale Indicates "NO BAG" when there is a bag in place [on newer scales with a GSE scale controller]. (The purpose of this feature is to prevent the scale from feeding material when a bag is not in place to catch it) (Applies to 6128 Scale) |
Scale is designed to execute the preprogrammed "start delay", then Tare out the bag weight, then look for 0.14# of material to enter the bag within a short period of time after starting the bulk fill process. If 0.14# of gross weight is not detected, the scale will register a "NO BAG" error. Start Delay is Not Long Enough to allow Load Cell to Stabilize and correctly detect the 0.14# gross weight. Solution: Increase Start Delay in the program. Dirt or product accumulation on the load cell is preventing the load cell from deflecting fast enough to register the required +0.14# gross weight. Solution: Clean the Load Cell. Cable ties around the air lines or the air lines themselves are too tight and are restricting free movement of the scale head. Solution: Make sure the air hoses connected to the bag spout are not too tight. Remove excessively tight cable ties or install longer air lines if necessary. |
Bag Releases Before Being Up to Weight: (Applies to 6128 Scale) |
Air pressure to bag clamps or bag holder cylinders is too low to hold bag. Solution: Increase pressure. Pressure should be set to approximately 60 PSI Bag Clamp or Bag Holder Facing is worn. Solution: Replace the rubber facing. Unclamp delay time is set too short. Solution: Increase unclamp delay time. Bag clamp(s) diaphragm is leaking. Solution: Replace defective diaphragm(s). |
