How does an Automatic Bulk Scale Work?
A weighing cycle is broken down into 4 phases:
When the cycle starts, the electronic system checks that all startup conditions are met.
Phase A - The feed gate opens to fill the weigh hopper.
The upper garner provides a constant supply of product to the scale. Typically, this garner is equipped with a capacitive level sensor disabling the opening of the feed gate if the required volume of product is not present. However, if the space is limited and prevents the installation of a level sensor, the I410 ABS program will properly function without this upper bin detection input.
Phase B - The feed gate closes and "gross weight" is saved.
Phase C - The discharge gate opens to release the product isolated in the weigh hopper.
The lower bin will discharge the product weighed. This bin must be fitted with a capacitive level sensor disabling the opening of the discharge gate if the volume available is inadequate to hold the product isolated in phase B. The volume checked by this level sensor varies depending on the scale model used.
Phase D - The discharge gate closes and "tare weight" is measured.
The net weight of the cycle is calculated and updates the total amount displayed on the I410 ABS terminal.
