  • Page 8: Front Panel Operation

    4 Operation 3. OPERATION The Model 114 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: Signal Timeout

    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 14: Programming

    10 Operation 4. PROGRAMMING The Model 114 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 (ie. the dark grey strip along the bottom of the enclosure) and turning it end for end and replacing it.

  • Page 15: Program Steps

    4.1 PROGRAM STEPS Step Comment CAL 01 Scaling Factor - whole numbers. CAL 02 Scaling Factor - digits after the decimal point. The Scaling Factor is the pulses per unit of measure (eg. pulses/litre, pulses/gallon, etc). The Scaling Factor can be programmed in the range of 0.0001 - 999,999.

  • Page 16: Example

    12 Programming 4.2 EXAMPLE A flowmeter produces 20.538 pulses per litre and has a maximum flowrate of 150 litres/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 17: Valve Control And Dc Power

    5. VALVE CONTROL AND DC POWER The Model 114 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. As the instrument has an internal battery backup it will power the instrument if DC power is interrupted, but these batteries are not capable of powering the solenoids or sensors if they require external power (see section 6 for further...

    6. BATTERY BACKUP The Model 114 has bettery backup for the instrument if the supply has been interrupted. The lithium battery packs provide sufficient capacity to power the instruments for up to 2 years and the operator is warned of a low power condition by a message on the LCD display.

    8. INSTALLATION 8.1 WALL MOUNTING A wall mounting bracket is supplied with each instrument. Round head screws should be used to attach the bracket to the wall (countersunk screws should not be used). The bracket is mounted first with the tray section at the bottom. The instrument is then mounted on the bracket with two screws as shown below.

    20 Installation 8.2 REMOVING THE FRONT PANEL The front panel should be removed as follows: 1. Remove the top and bottom cover strips (ie. the dark plastic strip) by levering a screwdriver under one end. 2. Undo the screws retaining the front. Do not remove the screws, they are retained by O-rings.
