ALSTOM AB121 Control card

Tare Tare is the weight of an empty container. A tare value subtracts from the gross weight measurement, providing the computation of the net weight (material without the container). The tare function can also be used to track the net amount of material being added to or removed from a vessel or container. In this second case, the weight of the material in the container is included with the tare weight of the container as tare. The display then reflects the net amount being added to or removed from the vessel. The tare value can be displayed with the net weight. The operation of this secondary display is determined in Setup at Terminal > Display.

Tare types and associated operations available on the IND780 include: • Pushbutton Tare • Auto Tare • Keyboard Tare (Preset Tare) • Clearing Tare • Table Tare ⎯ Manual Clear • Net Sign Correction ⎯ Auto Clear Pushbutton Tare Pushbutton tare can be configured in Setup as enabled or disabled. When this feature is disabled, the TARE scale function key cannot be used to obtain a tare. If pushbutton tare is enabled, pressing the pushbutton TARE scale function key initiates a semi-automatic tare. The IND780 will attempt to perform a tare process. If it is successful, the display changes to a zero net weight indication and the previous weight on the scale is stored as the tare value. The net mode will be indicated on the display

Keyboard Tare 

A keyboard (preset) tare is a numeric tare that is entered manually through the numeric keypad, received serially from a peripheral, or retrieved from the Tare Table memory. The preset tare value cannot exceed the capacity of the scale. Data entered is interpreted to have the same units as the current displayed value. Motion does not impact the entry of preset tare values. Keyboard tare can be configured in Setup as enabled or disabled. When disabled, the numeric keypad and the TARE scale function key cannot be used to obtain a tare.

Several conditions could inhibit the pushbutton tare function: • Motion—Pushbutton tare cannot be taken when the scale is in motion. If motion is detected when a pushbutton tare command is received, the IND780 will wait up to three seconds for a no-motion condition. If a stable (no motion) weight condition occurs before the three seconds expire, the pushbutton tare command is executed. If there is still motion at the end of three seconds, the command is aborted and a “Tare Failure – In Motion” error displays. • Pushbutton Tare Disabled—If pushbutton tare is configured as disabled, the TARE scale function key will not initiate a semi-automatic tare. • Negative Gross Weight—Any pushbutton tare attempted when the gross weight is at or below zero is ignored and a “Tare Failed–Too Small” error displays. Ensure that the gross weight is above zero.
