Hanna Instruments PCA 301 - Manuals

6 Two selectable chlorine level setpoints can be set by the op-erator: a proportional dosing setpoint and an alarm setpoint.Both setpoints control a SPDT relay. The proportional dosing setpoint analyzers is user-selectablewith a delta from 0.1 to 2.0 mg/L (ppm). The alarm level can be set by the use...

12 OPERATING DESCRIPTION Referring to the drawing on page 7 and the Fluidic Dia-gram on page 13, the Sample Line is connected to the instrument at the Sample Port (#16); an internal Regulator(#17) reduces the inlet pressure from a maximum of 4 bar(57.2 psig) down to 1 bar (14.3 psig); from the Regul...

14 INITIAL PREPARATION AND INSTALLATION INSTALLATION PERSONNEL Installation of the PCA 300 and PCA 301 family of Chlo- rine Analyzers should be undertaken by persons with technicalknowledge of the dangers associated with chemical exposureand electrical shock. Hanna Instruments assumes persons perfor...

22 START-UP INSTRUMENT POWER ON When the POWER switch is turned on or RESET is pressed,the moving words “Hanna PCA300” will appear. This dis-play will continue for 20 seconds. Then the concentration is set to0.00 mg/L. An indication appropriate tothe key pressed or, after 5minutes, the first mg/L re...

23 • Enter code 700 using the and keys. • Press DIAG and “brt” will be displayed. Then the bright- ness of the display will begin to change through the threelevels. • Press DIAG at one of the 3 brightness level and the analyzer will store that brightnesslevel. If DIAG is not pressed, the brightnessw...

25 PRIMING THE REAGENT SYSTEM A special diagnostic function included in the software pro-vides a convenient way to prime the peristaltic pump andreagent tubing during initial start-up. This decreases the timeneeded for instrument stabilization to about three minutes oruntil DIAG is pressed again. 1....

26 ANALYZER PROGRAMMING When power is first applied to the analyzer, programmableparameters of the analyzer are set to default values estab-lished at the factory. These values or any new values enteredby the operator are stored in nonvolatile EEPROM whichwill retain the programmed values in the even...

28 Example With the previously given values, sample rate 5 minutes andmeasured value 2.8 mg/L, the proportional dosing will beactive for the initial 2 minutes and will stop for the remaining3 minutes. In fact: 0.5 mg/L : 5 min = 0.2 mg/L (3-2.8) : X then X = 2 minutes. CONCENTRATION SETPOINT ALARM S...

31 • If you want to store the new setpoint promptly press REC.MIN again. Display will show “Stor” for a short time indicatingthat the new setpoint is stored and will return to the Chlo-rine concentration display. • If you do not want to change the setpoint, do not pressREC.MIN a second time. Thedisp...

32 • If you want to store the new setpoint, promptly press REC.MAX again. Display will show “Stor” for a short timeindicating that new setpoint is stored and will return to theChlorine concentration display. • If you do not want to change the setpoint, do not pressREC.MAX a second time.The display w...

37 DIAG 3.A.4 The reading on multimeter will slowly in- crease. When the desired value isreached, press DIAG again to store itand quit the mode. 3.B If the recorder zero reads too high 3.B.1 Press DIAG. The display will show the last diagnostic mode and the right-most numerical digit will blink. 3.B...

38 DIAG 3.C If the recorder full scale (upper limit) reads too low 3.C.1 Press DIAG. The display will show the last diagnostic mode and the right-most numerical digit will blink. 3.C.2 Enter code 102 using the and keys. 3.C.3 Press DIAG; “r up” will be displayed and the analyzer will execute this mo...

42 DIAG DIAG 3.B Enter code 112 using the and keys. 3.C Press DIAG; “– –” will be displayed and the analyzerand the multimeter will display the current mid-rangerecorder output limit. 3.D Press DIAG again to quit the mode. ADJUSTING THE LIGHT SOURCE If the sample blank is highly colored or turbid, t...

44 MAINTENANCE CALIBRATION REQUIREMENT Calibration of the PCA 300 and PCA 301 series of Chlo- rine Analyzers is not normally required. The DPD techniquefor measuring Chlorine concentration is well established andconsistent. Also, by measuring the sample blank absorbancyto establish the zero referenc...

46 Once reagents are completely ex-hausted, the system error LED will lit(while the relay remains activated) tonotify the user. CHANGING PERISTALTIC PUMP TUBING It is recommended that the peristaltic pump tubes be changedon a regular basis depending on sampling period and oper-ating time. For a 5 mi...

48 DIAG RELAY TEST In the relay test mode all three alarm relays close for aboutone second. 1. Press DIAG . The display will show the last diagnostic mode and the right-most numerical digit will blink. 2. Enter code 501 using the and keys. After the code is selected display will show “d501”. 3. Pres...
