FUNCTIONS
- instantaneous reading of the flow, in kg/h or t/h, display of the status of the system and of the dosed total, with analogue output (optional) proportional to the flow
- adjuster of the dosage hourly flow, with adjustment of the belt speed or of the material flow through the programmable analogue output. Completely adjustable PID adjustment algorithm (proportional, integral, derivative)
- 4 selectable operation modes, for completely manual or completely automatic dosages, managed by remote master through Sysway, Modbus (standard fitted) or Profibus (only with option) protocols
- reading filter of the hourly flow with configurable incidence and speed depending on the system
- relay contacts dedicated for the complete management of the alarms and the blocks for off weight, off flow and belt side-slipping
- management of the dosage total under way and general total of dosages, printable and clearable independently from each other
- programmable dosage target upon weight or upon time, with relative contact
- management of the slow flow with programmable activation threshold, for more precise dosages
- calibration of the flow reading function, for perfecting the dosage performances
- impulse counter of the accumulated quantity through relay contact, for direct communication with PLC or external devices
- programmable delay at the start, for synchronisation of various CPW03BELT systems in the dosage of material mixtures
- completely programmable printouts, for compatibility with any ASCII printer manageable through the serial port; printing of the dosage data, of the system statuses and of the totals
- Sysway, Modbus (standard fitted) or Profibus (option) communication protocols) FLOW READER FUNCTIONING
The flow reader mode provides for the display of the hourly flow passing on the belt and the display of the status of the system and the accumulated total.
By closing the dosage start input, the system waits for the eventual set synchronisation time and enables the dosage output; if the analogue output has been configured, it transmits a signal, in voltage or in current, proportional to the hourly flow; furthermore it is possible to interrogate the instrument through the serial line and configure the setpoints through the fitted Modbus and Sysway protocols or the optional Profibus one.
The dosage ends upon reaching the configured target, or by reopening the start input. If a printer is connected, the data of the finished dosage is printed
FLOW REGULATOR FUNCTIONING
The flow adjuster mode provides for the display of the hourly flow transitioning on the belt and the display of the status of the system and the accumulated total.
Furthermore, during the dosage, the instrument adjusts the flow in order to keep it constant equal to the set flow target: if the flow increases, the instrument decreases the value of the analogue output in order to decrease the belt speed or the flow of material extracted from the silo; on the other hand, if the flow decreases, the instrument increases the value of the analogue output in order to increase the belt speed or the flow of material. The adjustment of the flow is obtained through the completely adjustable PID (proportional, integral, derivative) control.
By closing the dosage start input, the system waits for the eventual set synchronisation time and enables the dosage output; if the analogue output has been configured, this transmits a signal, in voltage or in current, proportional to the hourly flow; furthermore it is possible to interrogate the instrument through the serial line and configure the setpoints through the fitted Modbus and Sysway protocols or the Profibus one (option). The dosage ends when the set target is reached, or by reopening the start input. Furthermore, it is possible to set a dosage slowing threshold: when this threshold is missing from the weight to be dosed, the instrument slows the system in order to maintain the "slow flow" set until the target is reached. If a printer is connected, the data of the finished dosage is printed.
