Diagram of automatic dosage |
SINGLE PRODUCT DOSAGE (LOAD MODE)
- the indicator gives a start command
- it is verified whether on the scale there is the eventual prefixed tare and whether the weight is stable
- the instrument executes the automatic tare
- one enables the quick dosage output and the product one: the dosage starts at the maximum speed
- when the weight reaches the target to be dosed - slow dosage weight - material weight in flight (if automatic dosage) threshold, the approximate dosage relay is disabled, and the fine mode is enabled upon reaching the target to dose - material weight in flight
- (if automatic dosage) threshold, the fine dosage relay is disabled;
- the instrument waits, in the configured time, for the fall of the material in flight, executes the tolerance check and stores the data of the executed dosage; then the data of the executed dosage is transmitted through the serial line, for the printing or the storage on the PC/PLC
- the instrument automatically passes to the complete discharge phase of the scale, enabling the dedicated relay
- when the weight descends below the discharge end threshold, the discharge relay is disabled, the dosage result is printed, and the instrument waits for a new start command, or if a cycle of dosage repetitions has been set, it automatically starts the next dosage
SINGLE PRODUCT DOSAGE (UNLOAD MODE)
- the indicator gives a start command
- it is verified whether on the scale there is enough material to execute the dosage and whether the weight is stable;
- the instrument executes the automatic tare;
- the fast dosage output and the product one are enabled: the dosage starts at the maximum speed;
- when the unloaded weight reaches the target to dose - slow dosage weight - material in weight threshold (if automatic dosage), the approximate dosage relay is disabled, and one proceeds in the fine mode;
- upon reaching the target to dose - material weight in flight threshold (if automatic dosage), the fine dosage relay is disabled; the instrument waits, in the configured time period, for the fall of the material in flight, executes the tolerance check, and stores the data of the executed dosage; the data of the executed dosage is transmitted through the serial line, and is useful for the printing or the storage on PC/PLC;
- The instrument waits for a new start command, or, in the case that a cycle of dosage repetitions has been set, it automatically starts the following dosage.
- NOTE: at every dosage start or at the end of each dosage, the instrument verifies whether the material on the scale is sufficient for executing a new dosage cycle, otherwise the reloading relay is enabled; the reloading ends upon reaching the programmable threshold of charge end
