    0-100 or 0-1000 PPM by proper field calibration. The analog output signal may be spanned for smaller ranges within the overall operating ranges if desired. A15/82 monitors are designed to operate on sample temperatures from 0° to 50 °C. Because water is flowing through the chemistry module at a low rate, this unit cannot be exposed to temperatures below 0°...

    Model A15/82 Fluoride Monitor with Auto-Calibration The chemistry module contains the components required to condition the sample and measure the fluoride concentration under stable conditions. This package includes sample and buffer pumps, the fluoride ISE, and a sensor flow chamber.

  • Page 12: Sample Inlet Overflow

    Model A15/82 Fluoride Monitor with Auto-Calibration SAMPLE INLET OVERFLOW The water sample supplied to the monitor is connected to a special overflow chamber. This is done to insure that the sample flowrate to the monitor is sufficient to insure that fresh sample is always available at the sample pickup point.

  • Page 13: Buffer And Calibration Standard Bottle Holders

    Model A15/82 Fluoride Monitor with Auto-Calibration BUFFER AND CALIBRATION STANDARD BOTTLE HOLDERS Two bottle mounting brackets are supplied so that the buffer and fluoride standard solution can be located conveniently below the chemistry module. The brackets are designed for wall mounting, and will hold one gallon plastic containers.

  • Page 14: Reagent And Fluoride Standard Pickup Tubing Connection

    Model A15/82 Fluoride Monitor with Auto-Calibration REAGENT AND FLUORIDE STANDARD PICKUP TUBING CONNECTION A special rubber stopper with a ceramic support tube is supplied for the buffer and fluoride standard bottles. If necessary, adjust the ceramic tube so that it does not hit the bottom of the solution bottles. A length of pickup tubing is supplied for each of these pickup assemblies with a small filter attached to one end of the buffer tubing.

  • Page 15: Electrical Connections

    ELECTRICAL CONNECTIONS Wiring connections to the A15/82 are made to the back of the monitor. The terminal blocks on the back of the monitor are pluggable terminals for ease of wiring. Power and alarm relay connections are made to the lower terminal block while sensor and analog output connections are made to the upper block.

  • Page 16: Figure 9 - Figure 9 Chemistry Module Power Connection

    Model A15/82 Fluoride Monitor with Auto-Calibration The fluoride chemistry module requires AC power for operation of internal sample and buffer pumps. An AC power cord is supplied. Permanent wiring should be made to the terminals shown in Figure 9 below. The sensor wire is an unbroken coaxial wire running directly into the monitor.

  • Page 17: Start-Up

    Model A15/82 Fluoride Monitor with Auto-Calibration START-UP Prior to operation, recheck electrical connections to be sure everything is in accordance with Figure 8 and Figure 9. If everything is in order, power may be applied. When power is turned on, the display will come up with a program and version number, which will remain on the display for a few seconds.

  • Page 18: Front Panel Lock

    Model A15/82 Fluoride Monitor with Auto-Calibration FRONT PANEL LOCK The key switches on the front panel of the monitor can be used for both changing the display and for calibrations and setpoint adjustments. When the monitor is shipped from ATI, all functions are accessible.

  • Page 19: Configuration

    Model A15/82 Fluoride Monitor with Auto-Calibration CONFIGURATION The electronics for the Fluoride system are designed to be as flexible as possible. A number of programming functions are provided in the CONFIGURATION menu and are protected by an access number, which must be entered to allow changes in these settings. Some settings are for factory use only, while others are used for customer selection of certain operating parameters.
  • Page 20 Model A15/82 Fluoride Monitor with Auto-Calibration SET A F.: LO (OR HI) This routine allows the function of setpoint A to be defined as either low or high. When LO is selected, relay A acts like a low alarm, with the relay activating when the measured fluoride is below the setpoint.
  • Page 21 Model A15/82 Fluoride Monitor with Auto-Calibration CALIBR. T: 3.0’ This routine specifies the amount of time that fluoride standard will be fed into the chemistry module during the automatic calibration routine. The default is 3 minutes, which is the recommended interval. Do not set this value for less than 2 minutes. A longer interval can be used if desired, but is not normally necessary.

  • Page 22: Chemistry Module Startup

    Model A15/82 Fluoride Monitor with Auto-Calibration CHEMISTRY MODULE STARTUP After mechanical and electrical installation is complete, the system is ready for operation. The chemistry module should be placed in operation first. The electronics do not need to be powered during chemistry module startup, but can be powered if desired.

  • Page 23: Automatic Calibration Valve

    Model A15/82 Fluoride Monitor with Auto-Calibration AUTOMATIC CALIBRATION VALVE A 2-way pinch valve is mounted on the bottom of the chemistry module between the sample and reagent pumps. This valve is not required for operation, but is used to automatically switch calibration standard into the measuring cell when called for by the monitor.

  • Page 24: Operation

    Model A15/82 Fluoride Monitor with Auto-Calibration OPERATION With the chemistry module in operation and power turned on to the monitor, the system should now be displaying a fluoride concentration from the sample. The value measured initially will probably be fairly close to the actual value, but the monitor is not factory calibrated.

  • Page 26: Automatic Calibration

    MIXING FLUORIDE BUFFER SOLUTION The buffer solution used in the A15/82 Fluoride Monitor is designed to adjust the sample pH to about 5.3 and to provide a relatively stable ionic strength in the sample to allow stable fluoride measurement. The buffer solution can be purchased from ATI or can be mixed by the user if desired.

  • Page 27: Fluoride Calibration Standard

    Model A15/82 Fluoride Monitor with Auto-Calibration FLUORIDE CALIBRATION STANDARD The automatic calibration routine uses a fluoride standard that must be prepared in a 1 gallon container and connected as shown in Figure 5. A 1 gallon container of fluoride standard will last in excess of 6 months assuming if calibration is done every 24 hours and in excess of 1 year if calibration is done every 48 hours.

  • Page 28: Control & Alarm Outputs

    Model A15/82 Fluoride Monitor with Auto-Calibration CONTROL & ALARM OUTPUTS The Fluoride Monitor is equipped with four relay outputs. Two of these outputs are designated control relays, a third is used for alarm functions, and the fourth is used to activate a cleaning cycle. The cleaning cycle function is not implemented in this design as it is not needed for drinking water measurements.

  • Page 29: Alarm Relay

    Model A15/82 Fluoride Monitor with Auto-Calibration ALARM RELAY The A15/82 contains a relay designated as an alarm relay. This relay may be used to warn of various conditions that might indicate operational problems. The relay will activate on either high or low fluoride conditions, and can be used to indicate failure of the control relays to maintain proper control.

  • Page 30: Maintenance

    Model A15/82 Fluoride Monitor with Auto-Calibration MAINTENANCE The A15/82 Fluoride Monitor will generally provide unattended operation over long periods of time. With proper care, the system should continue to provide measurements indefinitely. For reliable operation, maintenance on the system must be done on a regular schedule. Keep in mind that preventive maintenance on a regular schedule is much less troublesome than emergency maintenance that always seems to come at the wrong time.
