The K402 adds multiple-product configuration to the K401, making it ideal for applications where there are a variety of products that have fixed attributes that need to be recalled.

Powerful product configuration allows for parameters to be stored for each product. For each product the following can be stored:

  • set point target
  • piece weight
  • units conversions
  • full accumulation data

Products can be recalled easily by the operator by using the product name - either select from the most recently used 10 products or use an alphanumeric product search via the keypad. Product selection via an external thumb-wheel is also


Counting is made easy with either the piece weight is entered or determined through a sample. This piece weight can then be stored against the product id.


Multi-segment display assists the operator for piece weight counting by displaying the number of pieces on the primary line and the piece weight on the secondary line. 


Flexible set point configuration for improved system integration. A set point can be individually configured to instrument status or weight target triggers. Each set point can be:

  • Independently configured for a given function
  • Configured for high or low logic
  • Defined to use a given weight source Gross, Net, Alternate Units or Piece count
  • Logic set points allowing for AND, OR, XOR across multiple sources
  • Selectable source: I/O, the status of the instrument, another setpoint or a register value
  • Set point naming
  • Settable delays before a set point becomes active or inactive
