    • No-signal alarm
    • Ticket printing with time and date

    The Contrec 430D Batch Controller is extraordinarily flexible and easy to operate. Batches can be started, paused, stopped, and reset via four operational keys, and batch quantities and calibration parameters are entered via a 12 key numeric keypad. Batch Total, Flow Rate, Accumulated Total, and Preset Value can all be displayed in engineering units on the green LED display. The 430D will accept most pulse signals and frequency, including mV outputs from turbine flowmeters, and two-wire proximity switch outputs. Automatic Overrun Compensation Based on previous batches, the 430D batch controller will automatically compensate for any overrun, which may be caused by slow closing valves.

    Printer or Computer Interface

    An RS442/485 and RS232 option is available for printer and computer interface. The interface allows the 430D Batch Controller to be fully controlled from a computer.
    Software drivers are included for a number of printers and can print a ticket with time and date, a sequential delivery, batch number, and the batch and accumulated totals. An optional header for the ticket can also be printed.

    Flow Totalizer Mode

    The 430D can be configured during calibration to operate as a Flow Rate Totalizer as distinct from a batch controller.
    In this mode, the RUN, STOP, and Batch Set keys perform no function. The Rate key is used to toggle the display between Rate and Resettable Total.
    By pressing and holding the Accum key, whenever the instrument is not in data entry mode, the Accumulated Total will be displayed.

    Versatile Performance Options

    The instrument will operate from 14 to 28V dc or from 110 to 220V ac mains.
    The front panel is fully waterproof to NEMA 4X (IP65) and chemical resistant.
    A total conversion feature enables the rate to be displayed in one engineering unit (e.g., gallons/minute) and the totals to be displayed in another engineering unit (e.g., barrels).
    The standard instrument is supplied as a panel mount. Field enclosures are optionally available.
    Simple keypad operation and four LED’s indicate the operational status at all times.
    Four operational keys and a full numeric keypad on the front display enable the batch quantity to be set, and batch operations to be started, paused, stopped, or reset.

    Batch Quantity Set

    When the Batch Set key is pressed, the batch quantity can be entered via the numeric keys. Once set, return to Run mode by pressing the Batch Set key again.
    The batch quantity can only be set while the instrument is in a non- operational state, such as when the batch is complete or paused.
    Once set, the batch quantity will be retained in non-volatile memory and will not alter until changed by the user.
    To check the batch quantity while a batch is in progress, press the Batch Set key.

    Starting a Batch

    To begin the batch, Press the RUN key. The Run LED will light, and the instrument will begin to totalize from zero or, if programmed for the count down mode, the display will decrement from the batch quantity.

    Stopping a Batch

    The batch can be stopped at any time by pressing the STOP key. To continue the batch press the RUN key, or to abort the batch press the STOP key again.
    When the batch has been interrupted, the Pause LED will light. If the batch is aborted the Stop LED will light.

    Resetting a Batch

    The instrument can be programmed to reset in either of two ways.
    By manually pressing the Reset key, at the end of a batch, the Batch Total will be reset to zero (if programmed to count up) or to the preset quantity (if programmed to count down).
    If Auto Reset is programmed, however, the Batch Total will automatically reset when the RUN key is pressed.

    Single or two-stage valve control
    Two output relays provide control for single or dual-stage valve operation. The first relay will energize as pre-start and de-energize when the batch is complete.
    The second relay can be programmed to energize slow-start or slow stop by setting the time or quantity before completion of the batch. This feature enables a slow startup and slow shutdown of the flow.
    The Batch Controller can also be programmed to count up from zero or down from the batch quantity.
