I. INTRODUCTION The RA-1000 Residual Analyzer/Controller is an amperometric instrument designed to continuously analyze residual levels of free or total chlorine, chlorine dioxide, or potassium permanganate in water, wastewater or liquids containing particulates. II. SPECIFICATIONS Power Supply 115/230 VAC Switch selectable. Power Consumption 12W Display LCD, backlit, 16 characters by 2 lines, 5mm character height,5x8 character matrix. Pushbuttons Four, tactile dome.
Ambient Temperature Range: 35 degrees to 120 degrees F (2 degrees to 50 degrees C) Sample Temperature Range: 35 degrees 120 degrees F (2 degrees to 50 degrees C) Sample Limitations: Samples containing high concentrations of metal ions or certain corrosion inhibitors my effect analyzer operation.
IV. INSTALLATION A. WALL PANEL MOUNTING 1. B. Position the analyzer panel on a wall at eye level and as close as possible to the sample source. Secure with bolts, leveling the analyzer before securing. HYDRAULIC CONNECTIONS C. 1. Connect the necessary length of drain hose to the drain outlet on the analyzer. Secure with a hose clamp. Route hose to maintain a gravity fed drain (downward slope). 2.
NOTE: ALL WIRING MUST COMPLY WITH APPLICABLE LOCAL AND NATIONAL ELECTRICAL CODES. 1. Remove four (4) screws securing side cover and remove cover. 2. Connect input power (120 Vac standard) to N,H,G terminals. 3. Connect current output and alarm contacts. NOTE: DO NOT RUN LINE VOLTAGE AND SIGNAL VOLTAGE IN THE SAME CONDUIT. V. REAGENTS A pH buffering solution or carbon dioxide gas is required for analyzer operation.
ANALYZER RANGE 10 grams for 0.5 mg/l 40 grams for 2.0 mg/l 60 grams for 3.0 mg/l 100 grams for 5.0, 10, 20 and 30 mg/l B. c. Shake until crystals are completely dissolved. d. Fill bottle to the top with distilled/deionized water; shake again. Pour contents into the reagent bottle through a fine strainer. The bottle will provide approximately a one week supply of reagent. Carbon Dioxide Gas When using carbon dioxide for pH buffering, a carbon dioxide gas flow rate of 200 cc per minute is required.
III. E. The analyzer requires a minimum stabilization time of 24 hours. During this time, reagents must be feeding into the cell . Under normal circumstances, reagent level will drop approximately 1" per 24 hrs. C. After stabilization, calibration may be required. Instruments are calibrated at the factory; at start-up Auto Zero adjustment is necessary to compensate for composition of the local water. OPERATION C.
C. 2. Stop sample flow. 3. Lift and rotate clip securing the reagent bottle. Raise reagent bottle approximately 2” and pull down on the valve stem until the hole in the cap is plugged. Remove reagent bottle. 4. Hold reagent bottle upright, unscrew and remove cap. Place open bottle close to clear tubing connector at adaptor. Carefully unscrew connector nut releasing clear tube and drain remaining reagent from the reservoir into the reagent bottle. Screw cap onto reagent bottle. 5.
ANALYZER. WHEN THIS ASSEMBLY IS WITHDRAWN, THESE SPHERES WILL DROP OUT. D. 1. Refer to OPERATION, Section B and proceed with Steps 1 through 7. Remove the adapter and all reagent. 2. Disconnect the wire from the gold electrode assembly. 3. While holding a bucket under the analyzer, unscrew the gold electrode by hand. As the assembly is withdrawn, the spheres will begin dropping out. Hold the bucket below until all the spheres are removed. Remove large o-ring on the electrode assembly. 4.
E. MOTOR REPLACEMENT 1. If the motor is to be replaced, remove the striker from the motor shaft. Install on new motor after turning the center set screw out approximately two (2) turns. 2. Turn the side set screw in striker until it contacts the motor shaft. The striker should be capable of sliding onto the motor shaft when force is applied. 3. Fit the striker on to the motor so a small space is between the top of the striker and the motor plate.
IX. TROUBLESHOOTING CHART NOTES: A. Verify sample flow at the analyzer intake between the overflow weir and the filter screen (500 cc/minute) )1 pint/minute) at 5 psig (0.3 bar). Verify constant sample flow through the analyzer by observing flow at the drains. SAMPLE MUST ALWAYS FLOW TO THE ANALYZER. B. Verify analyzer motor connection to proper power supply and operating. C. Verify reagent feed to the analyzer.
TROUBLE: PROBABLE CAUSE: Inability to zero. 1. Residual present in sample. CORRECTIVE ACTION: 1. TROUBLE: PROBABLE CAUSE: Improper reagent feed. 1. Faulty starwheel. CORRECTIVE ACTION: 1. TROUBLE: PROBABLE CAUSE: 2. Clean. See OPERATION, Section B. Check per OPERATION, Section B. Display blank. 1. Power OFF. 2. Bad connector or incorrect wiring to control unit. CORRECTIVE ACTION: 1. 2. C. Motor must turn counterclockwise, (top view). Inspect motor leads for proper connection.
MAIN RUN SCREEN The value displayed is the chlorine residual in ppm or mg/l. Below the residual value is a fifty segment bar-graph representation of the residual 4mA to 20mA output (PO1). RES 5.00 ppm [••••• ] SET 1 4 no label SET Displays the water temperature. The user is prompted to enter a password to enter a programming mode in which one can calibrate, set alarm set-points, and set the 4-20mA output range.
CALIBRATE CELL From the residual setup screen, press CELL to enter the cell calibration menu. CALIBRATE CELL ZRO SPAN ESC 1 2 3 4 ZRO SPAN no function ESC Zero cell input Set the current CL2 residual. Go back to the calibrate menu. CALIBRATE ZERO SELECTION SCREEN CALIBRATE ZERO MAN AUTO ESC 1 2 3 4 MAN AUTO no function ESC Manual zero Auto zero Go back to the calibrate cell menu. MANUAL ZERO SCREEN WAIT FOR... 0.
AUTO ZERO SCREEN AUTO ZERO 120s .. 0.0mV ESC This screen will automatically zero the cell input if there is a stable mV input for 120 seconds. If the auto zero successful, the instrument will display an auto zero successful message. If fifteen minutes pass without an auto zero, the instrument will display an auto zero failure message. The top, right side of the display shows a timer, and the bottom, left side shows the current cell mV.
0.00ppm UP DWN SET ESC 1 2 3 4 UP DWN SET ESC Increase CL2 value Decrease CL2 value The value entered is the CL2 residual at the time the STR pushbutton was pressed. Go back to the get sample screen CALIBRATING THE ANALOG OUTPUT For one to calibrate the analog output, an accurate DMM or equivalent current meter (20mA range) must be connected alone or in series with the 4 to 20mA (PO1) load.
SETPOINTS The RA-1000 has CL2 residual high and low relay (alarm) outputs. Press ALM from the RESIDUAL SETUP screen. Select either the LOW or HIGH set point. Use the up & down pushbuttons to set the trip point and press set to store the new value. To disable a set point, enter a zero value. A low set point is activated when the CL2 residual falls to or below the set point and is deactivated when the CL2 residual rises above the trip set point plus a 0.10 (0.010) ppm(mg/l) hysteresis.
