ATI Model A15/82 Fluoride Monitor with Auto-Calibration INSTALLATION The main installation requirements for the ATI Fluoride Monitor are mechanical installation of the monitor chemistry module, and sample inlet overflow chamber, connection of power to both monitor and chemistry module, and connection of sample and drain piping to the sample overflow chamber supplied with the system.
ATI Model A15/82 Fluoride Monitor with Auto-Calibration The optional NEMA 4X wall mount enclosure is a molded plastic unit that bolts directly to a wall or other flat surface. The enclosure is supplied with special mounting bracket for convenience in mounting the enclosure. A hinged door on the front of the enclosure provides access to operating controls, and a hinge on the back section is provided for convenience in wiring the unit. Figure 3 - NEMA 4X Wall Mount Dim.
ATI 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. Figure 4 provides dimensions for this unit, which is designed for wall mounting.
ATI 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. Most of the sample flowing to this assembly will simply go directly to the drain. Figure 5 shows the sample overflow assembly on its aluminum mounting bracket.
ATI 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.
ATI 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.
ATI Model A15/82 Fluoride Monitor with Auto-Calibration 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. A cable coming from the combination sensor is installed in the chemistry module at the factory.
ATI 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. In addition, a separate 5 conductor cable is supplied for connection of the temperature element and the automatic calibration control between chemistry module and monitor.
ATI 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. The display will then change to a display of the fluoride value and an indication of the status of control relays.
ATI 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. However, the adjustment and calibration functions can be locked in order to prevent unauthorized adjustments to the instrument.
ATI 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.
ATI Model A15/82 Fluoride Monitor with Auto-Calibration 9. 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. When HI is selected, the relay acts like a high alarm, activating when fluoride is above the setpoint. Setpoints are programmed in another routine described later in this manual. 10. SET B F.
ATI Model A15/82 Fluoride Monitor with Auto-Calibration 20. 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. 21. HOLDING T: 1.
ATI 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. No harm will result provided that relays or outputs are not being used for control.
ATI 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.
ATI 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. While the monitor contains an automatic calibration feature, a manual 2-point calibration must be done at startup.
ATI Model A15/82 Fluoride Monitor with Auto-Calibration for the glass electrode and -405 mV for the polymer sensor). Press ENTER and the display will indicate “P2 DECADE: 100.0”. Press the DOWN key once to change it to “P2 DECADE: 10.00” and press ENTER. The display will change to “P2 VALUE: 10.00”. Since the value of the standard is 10 PPM, no adjustment is necessary. Simply Press ENTER. 6. The display will change to “CAL POINT Nr. 3”. Press ENTER and the display will indicate “END POINT CAL?”.
ATI Model A15/82 Fluoride Monitor with Auto-Calibration AUTOMATIC CALIBRATION The A15/82 Fluoride Monitor performs an automatic calibration adjustment as often as the user desires. This automatic calibration routine corrects the monitor for small changes caused by electrode drift. Fluoride ISE sensors are quite stable over long periods of time when used in buffered samples, but electrode drift could cause errors of 0.1 – 0.2 PPM if not adjusted every week or two.
ATI 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. This standard must be mixed by the user during startup of the system.
ATI 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. The two control relays are both available only if the Auto Cal feature is disabled.
ATI 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.
ATI 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.
