Application Note: 2100 Bag filler using a single speed
Application Note: 2100 Bag filler using a single speed feeder
Application:
A weighing machine is to be used in a single-speed, single material, bag/box
filling application using a 2100. The 2100’s in-flight compensation
automatically adjusts the in-flight value at the end of every batch.
The 2100 can alert the operator to manually remove the filled bag/box or it can
trigger an external mechanism to remove the filled bag/box.
For 2100 - Bag Filler Using a Two-Speed Feeder refer to Application Note 3.

Operation:
In this example a 30kg weighing machine is used to fill bags to a maximum weight of 25kg. When
the 25kg maximum weight is reached, the feeder will stop and an audible sound will alert the
operator to manually remove the filled bag.
Step 1: The Operator loads an empty bag
onto the scale.
Step 2: A press of the BATCH key will start
the operation. The scale will TARE the bag
off and set the weight reading to zero.
Step 3: Relay 1 (Fill) activates, switching
ON the feeder. When the 25kg target is
reached, Relay 1 deactivates, switching
OFF the feeder.
Step 4: Relay 3 (Dump) activates,
switching ON the audible sound. The
Operator removes the filled bag from the
scale. Relay 3 deactivates and the 2100
resets ready for the next fill.

COMMENT
B = Sets the 2100 function key to work as a Batch control.
- = All other control settings are left blank.
S = Use Option A (output 1) as the (Slow) feeder.
N = Use Net weight (i.e. tare off at start).
O = The direction of fill is upwards (i.e. output changes state
when weight gets Over this point).
L = Set to Lower. Relay will turn on under target weight.
- = No alarm set.
Enter the final target weight for the bag.
D = Use Option C (output 3) as the Dump, or Discharge.
N = Display to show Net weight during unloading.
O, L = These options remain as the default settings (in this
example O and L).
- = No alarm set.
