  • Page 12: Operation

    Operation 3. OPERATION The Model 214Di Batch Controller accepts a frequency or pulse input from a wide range of flowmeters. The instrument is fully programmable with all operating parameters and calculation constants programmable from the front panel. The setup parameters are stored in a non-volatile memory and are retained for at least 10 years in the event of a power loss.
  • Page 13 Operation Switch Action Display Comments Press 2 "2" 345 Pressing the key will change digit and enables the next digit to be incremented. (The right arrow on the RUN key indicates to change digit.) Press PRESET 22345 Pressing PRESET returns the instrument to the Run mode and batches can now be run.

  • Page 14: Test Mode

    Operation ACCUMULATED TOTAL During a batch run, the Accumulated Total can be displayed by pressing the ACCUM TOTAL key. In the non-operational state (i.e. when the batch is complete), the ACCUM TOTAL key also functions as the PRESET key and enables the Preset quantity to be changed.

  • Page 15: Batch Operations

    Operation 3.3 BATCH OPERATIONS The operation of the Batch Controller is shown below: Batch PAUSE Quantity Reached Stop Run "on" state Output 1 "on" state Output 2 Start Time Prestop Quantity Two Stage Valve Control 3.3.1 Control Outputs The two solid state relay outputs can be set up to control a single valve or a dual valve with slow stop and/or slow start.

  • Page 16: Signal Timeout

    Operation The process can be stopped at any time by pressing the STOP key, whereby both outputs will immediately switch off. The process can then be aborted and the batcher reset by pressing the STOP key again, or the process continued by pressing the RUN key.

  • Page 17: Programming

    Programming 4. PROGRAMMING The Model 214Di is fully programmable, with all parameters being stored in memory. The Program Mode can be entered in one of two ways: 1. By removing the lower cover strip (i.e. the dark grey strip along the bottom of the enclosure) and turning it end for end and replacing it.

  • Page 18: Program Steps

    Programming 4.1 PROGRAM STEPS Step Comment Scaling Factor - whole numbers. Scaling Factor - digits after the decimal point. The Scaling Factor is the pulses per unit of measure (e.g.pulses/litre, pulses/gallon, etc). The Scaling Factor can be programmed in the range of 0.0001 - 999,999. Decimal Point for Total Display.

  • Page 19: Example

    Programming 4.2 EXAMPLE A flowmeter produces 20.538 pulses per litre and has a maximum flowrate of 150litres/minute. It is required to batch quantities in batches of around 300 litres and to alarm if there is no flow once the batch has started. To increase the accuracy of the batch, a two stage valve will be used and the flow will be slow prior to the end of the batch to enable a more accurate cutoff.

  • Page 20: Valve Control And Dc Power

    Valve Control and DC Power 5. VALVE CONTROL AND DC POWER The Model 214Di will operate from an external power source between 9- 28VDC and draws no more than 4mA. This enables the instrument to be powered from AC mains adaptors and eliminate the need to run mains voltage in the field.

  • Page 22: Battery Backup Version

    Note: No low battery warning will be displayed whilst there is external DC power connected. New batteries can be purchased via Contrec or our distributors and replaced in the field without compromising the IS approvals. There are two battery packs in each instrument and care must be taken to replace only one pack at a time so that there is always power connected to the memory.
