Exi batch controller Batching Master 110i/210i
The Batching Master is a control instrument, especially designed for the automation of batch functions, where precise results are required.
The Batching Master as a "stand alone version" is a fully functional device that requires just one power supply.
The operator has all information needed for a safe batching process local to the plant.
The batch is started directly at the point filling. If there is a failure in the system, the batch can be stopped immediately. Error messages are displayed in clear text.
Features
 | Local operation directly in the plant
| | Indication: |
pre-set,
batched quantity,
flow rate and
grand total | Compatible with all flow meters and actuators
| | Highest accuracy due to a 4 20 mA output with a 5-step shut down ramp and soft start ramp.
| | PID controller for the flow rate or maintaining pressure
| | Communication with supervisory systems via Modbus protocol
| | Display functions for text indications and the entry of loading data
| | Approval for custody transfer
|
Precise Batching
The Batching Master opens the valve with a 4 - 20 mA output signal. Because of the soft start ramp and the 5 shut down steps also small quantities are filled with highest accuracy. "Hammers" in high flow rate system are prevented. Flow metersLow flow rate monitoringIf the flow rate during the batch is too low, the Batching Master stops the batch after a pre-programmed time.
PID Controller function | Controlling the flow during the batch
| | Controlling the temperature or the PH during the batch
| | Pressure control function for LPG applications |
Terminal function
The terminal function is controlled by the serial interface. The host system can send text messages to the display of the Batching Master.
Operator acknowledgements such as confirming plant status, entry of order numbers or selection of a product can be carried out using the keyboard.
Product routing via function keys F1 - F3
Before the start of the batch, it is possible to chose a product way via the function keys.
Therefore it's possible to pre-program one question text and three texts that are dedicated to the function keys.
One digital output is dedicated to each function key.
Via this digital outputs it is possible to activate valves, pumps or product routings.
Batch systems for custody transfer
Approval No.:
German PTB.: 5.531/03.20
When tankers and wagons are loaded with a custody transfer batch system, it's not necessary to use expensive weighbridges. Also the dwell time for tankers being loaded will be reduced.
The batching data are logged to a printer. Using a multiplex system up to 16 Batching Masters can be connected at one printer. Different types of printers are available. Validation of batch dataSome processes such as those in the pharmaceutical and toiletry industries require a batch report to validate the batch data.
This is carried out by a mini PC and a ticket printer. Many Batching Masters can be connected to the mini PC via an RS 485 bus. Before a batch can be started, up to 10 text strings can be entered into the Batching Master, e.g. Operator Name, Batch No. or Product Name. Operator prompts in the form of text can be programmed into the mini PC to aid operators to enter the correct information.
At the end of a batch, the programmed text, all operator entries and the batch data will be printed on the ticket printer.
