  • Page 13: Operation

    Operation 3. Operation The Model 214D-1 uses a low power CMOS microprocessor to perform all control functions and calculations. The instrument is fully configurable with all operating parameters and calculation constants user settable. (See Section 5 entitled "Configuration" for information on configuring.) All parameters and constants are stored in a non-volatile memory which retains data without battery backup for a minimum of 10 years.

  • Page 14: Front Panel Operation

    Operation Front Panel Operation The four key operation makes the operation of the Batch Controller very easy. 3.1.1 Setting the Batch Quantity The batch quantity is set as follows: Switch Action Press BATCH SET Press r Press w Press BATCH SET Once set, the batch quantity will be retained in the non-volatile memory and will not alter until changed by the user.

  • Page 15: Starting A Batch

    3.1.2 Starting a Batch To start the process the RUN key is pressed. The Run LED will light and the instrument will begin to totalize from zero or, if programmed to count down, the display will decrement from the batch quantity. The batcher has two control relays which are energized and de- energized as described in Section 3.2.

  • Page 16: Limit On Batch Size

    Operation Accumulated Total On the next press of the DISPLAY key, the display shows ACC for one second followed by the accumulated total. Accumulated Total cannot be reset during normal operation. 3.1.6 Limit on Batch Size To prevent accidental entry of large batch quantities, a maximum batch limit can be set during configuration.

  • Page 17: Batch Operations

    Batch Operations The Batch Control functions can be configured to operate in one of two ways. 1. At the end of the batch, the STOP key must be pressed to reset the Batch Total. (This must be done before another batch can be started.) Operation HP289...
  • Page 18 Operation 2. If Automatic Reset is configured on, a new batch is commenced each time the RUN key is pressed. The Batch Controller can be configured to either count up from zero on each batch or to count down from the preset batch quantity. HP289...

  • Page 19: Control Relays

    Operation 3.2.1 Control Relays The two control relays can be set up to control a single valve or a dual valve with slow-stop and/or slow-start. Alternatively, the second relay can be used to control a pump. The relay operation is shown on the previous two pages. A time delay between the Batch Start and the time when Relay 2 energizes can be set to provide a soft start up.

  • Page 20: Signal Timeout

    Operation 3.2.2 Signal Timeout The Signal Timeout period defines a time interval which is used to detect if the flow has stopped. If there is no signal input for a time greater than the Signal Timeout period the flow is deemed to have stopped.

  • Page 21: End-Of-Batch

    Operation 3.2.3 End-of-Batch The End-of-Batch is defined as being when the Batch Quantity is reached, the flow has stopped, and the Signal Timeout period has expired. If the Signal Timeout is set to zero, the End-of-Batch is defined as being when the Batch Quantity is reached, regardless of whether the flow has stopped.

  • Page 22: Auto Restart

    Operation 3.2.4 Auto Restart The Batch Controller can be configured to continually repeat the batch process. This mode of operation is selected during the configuration process. The process is started by pressing the RUN key whereby the normal batch operation is commenced. After reaching the End-of-Batch (see Section 3.2.3), the Batch Controller will then wait for a pre- programmed period before automatically resetting and starting the batch process again.

  • Page 23: Automatic Overrun Compensation

    Operation 3.2.5 Automatic Overrun Compensation The Batch Controller can be configured to automatically compensate for any overrun at the end of a batch. Typically, this is due to the slowness of a valve to close or a pump to stop pumping on receiving a signal from the Batch Controller. The result is that the batch quantity will always read higher than the batch quantity set.

  • Page 24: Calculation Of Rate And Total

    Operation Calculation of Rate and Total 3.3.1 Frequency Input The flowrate, R, is calculated as follows: where f is the input frequency in Hz. H is the timebase of rate and is 1 for seconds, 60 for minutes,3600 for hours, and 86,400 for days. is the Scaling Factor.

  • Page 25: Filtering

    Operation 3.3.2 Filtering Frequency fluctuations caused by pulsating flow through a flowmeter, often makes the Rate impossible to read with any precision. The Batch Controller has a digital filter which will average out these fluctuations and enable the Rate to be read to four digit accuracy. The degree of filtering is fully configurable which means that highly accurate and stable readings can be obtained without excessive lag.
  • Page 26 Operation Table 1 - Response to a step Input (in seconds). Note: if A is set to 1, there is NO filtering of the input signal. HP289...

  • Page 27: Total Conversion

    Total Conversion The 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 Scaling Factor is always set in the unit relating to Rate and the Total Conversion constant is a division factor which can be used to convert the totals to the different unit.

  • Page 28: The Output Pulse And Flow Alarm

    Operation The Output Pulse and Flow Alarm An OUTPUT PULSE is available on terminal 10 for driving remote counters and produces a pulse each time the Accumulated Total increments by one digit. For example, if the Accumulated Total has a resolution of 0.01 gallons, a pulse is produced each 0.01 gallons.

    Installation 7. Installation General Terminal designations for the Model 214D Batch Controller are given on the following pages. The cutout hole in the panel should be 5.5" (139mm) wide x 2.6" (67mm) high. Two side clips are supplied to secure the instrument into the panel. A case grounding point is provided via a ground lug on the side of the case.
  • Page 51 should be as short as possible and connected to the grounding lug on the side of the case. In order to comply with the requirements for Electromagnetic Compatibility as per EMC-Directive 89/336/EEC of the Council of European Community, this wiring practice is mandatory. Although it is also possible to connect shields to the signal ground (terminal 2) this practice is not in accordance with EMC directives.

    8. Trouble Shooting Batcher does not reset The Signal Timeout has been set to an excessively long period and has not timed out at the end of the last batch. Batch will not start or relay 1 will not close Ensure that the instrument has not timed out as controlled by the Signal Timeout and that a Flow Alarm condition does not prevail.
  • Page 54 Trouble Shooting Scaling Factor should be set to 1 and the Resolution to whole numbers. Counting erratically This can be caused by two factors: § Setting the input circuit incorrectly § Lack of shielding on the input wiring Ensure that the input selection DIP switch is correctly set for the flowmeter attached.
