Introduction HP289 2B This page intentionally left blank..
Specification 3 HP289 2. Specification General Display: 6 digit LCD. 0.7" (17.8mm) high digits Display Update Rate: 0.25 seconds Transducer Supply : 8-24VDC field adjustable, 50mA maximum Power Requirements : DC: 11.
4 Specification HP289 Pulse Output Pulse Width: 10msec (negative going pulse) Maximum Duty Cycle: 49 pulses per second Output: Open collector transistor will sink 100mA. Scaling: The pulse output is scaled and outputs one pulse each time the accumulated total increments.
Operation 5 HP289 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.
6 Operation HP289 3.1 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 Display Comments Press BATCH SET Batch "Batch" is displayed for one second followed by the batch quantity last entered.
Operation 7 HP289 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.
8 Operation HP289 Accumulated Total On the next press of the DISPLAY key, the display shows ACC for one second followed by the accumulated total. The 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.
Operation 9 HP289 3.2 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.
10 Operation HP289 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.
Operation 11 HP289 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.
12 Operation HP289 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.
Operation 13 HP289 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.
14 Operation HP289 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.
Operation 15 HP289 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.
16 Operation HP289 3.3 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.
Operation 17 HP289 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.

Operation 19 HP289 3.4 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.
20 Operation HP289 3.5 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.
Operation 21 HP289 Connection of Output Pulse/Flow Alarm is as follows: Driving an External Relay or Impulse Counter Driving a Logic Input such as a PLC or Electronic Counter.
22 Options HP289 4. Options 4.1 The RS232/422/485 Interface Option With this option installed, the circuits for both the RS232 and RS422/485 interfaces are provided as standard. They can be used to interface to both printers and computers. A number of standard printer protocols are built into the instrument.
Options 23 HP289 4.1.2 Multipoint Communication Multipoint Communication is a system whereby a number of instruments can be addressed over a dual twisted pair interface. Up to 32 instruments can be connected to a common bus using the RS422 and RS485 interfaces as shown below.
24 Options HP289 Figure 2 RS485 Interface.
Options 25 HP289 4.1.3 Communication Protocol The RS232/422/485 option has a real time clock and enables the time and date to be set and printed on tickets . The date format can be European (days/months/years) or USA (months/days/years) while the time is on a 24 hour clock.
26 Options HP289 input is usually connected to the "Data Buffer Full" output from the printer. If the printer buffer is large enough to handle the message output from the instrument, then this input need not be used and should be left unconnected.
Configuration 27 HP289 5. Configuration The Configuration process enables the Setup Parameters to be configured, as well as enabling the input signals to be checked.
