PRELIMINARY EXAMINATION

Warning: Identifies conditions or practices that could result in personal injury or loss of life.

Note: Because of the inherent dangers in handling chemical samples, standards and reagents, HANNA Instruments strongly recommends the users of this product to review the Material Safety Data Sheets and become familiar with safe handling procedures and proper usage prior to handling any chemicals.

The Hanna Instruments PCA310, PCA320, PCA330 and PCA340 series of chlorine, pH, ORP and temperature analyzers are microprocessor controlled, process analyzers which continuously monitor a sample stream for chlorine content, pH, ORP and temperature values. The PCA310 - PCA340 monitor the free chlorine or total chlorine in the 0.00 to 5.00 mg/L range depending on the factory settings and used reagents. In the DPD Colorimetric method, N, N-Diethyl-p-phenylenediamine indicator and a buffer are mixed with the sample.

The resulting chemical reaction causes a magenta color to form. The color intensity is proportional to the concentration of chlorine. The color intensity is measured photometrically (with a light beam and a

GENERAL DESCRIPTION

photodetector) and converted to chlorine concentration, in mg/L, which is displayed on the front panel. Indicator and buffer reagent bottles are placed directly into the instrument case. With a sampling period of

5 minutes, reagents need to be replenished about once a month. The reagent bottles are easily visible through the transparent window allowing the operator to check the reagent levels.

PCA320, PCA330 and PCA340 analyzers use HI1005 probe to continuously measure the pH of

the sample stream in the range of 0.00 to 14.00 pH. The sample temperature is measured in the

5.00 to 75.00 °C range. pH and temperature are displayed on the front panel. pH value is corrected with temperature.

PCA330 analyzer use HI2008 platinum ORP electrode to continuously measure the sample ORP value.

The pH/temperature combined sensor and the ORP sensor are placed inside the case, directly in the sample stream.

The case of PCA310 - PCA340 analyzers meet NEMA 4X, 12 and 13 standards. Molded fiberglass polyester has outstanding chemical and temperature resistance.

The case provides wall mounting capability and door gasket assures a watertight and dust-tight seal. The electrical and hydraulic connections are made through the side of the enclosure. The front cover is secured with two lockable latches.

Four chlorine level setpoints can be adjusted by the operator: a proportional dosing setpoint, two alarm

setpoints and a minimum level for dosing. The proportional dosing factor (1/∆ is user selectable with

a delta between 0.1 and 5.0 mg/L (ppm)). Chlorine dosing system controls a SPST relay. Each chlorine alarm can be enabled or disabled. Three pH level setpoints can be adjusted by the operator: a dosing setpoint and two alarm setpoints.

The pH control mode is user selectable: on/off or proportional dosing.

The proportional dosing factor (1/∆) is user selectable with a delta between pH 0.1 and 2.0 . The

on/off dosing hysteresis is user selectable between pH 0.05 and 2.00. pH dosing system controls a SPST relay.

Each pH alarm can be enabled or disabled. For temperature and ORP, two alarm levels can be set by the user. Each temperature or ORP alarm can be enabled or disabled. Alarm condition controls a SPDT relay. A system error feature provides relay activation to signals need for operator intervention. System error condition controls a SPST relay. For PCA310 - PCA330 series the voltage output ranges of 0-10 mV, 0-100 mV, 0-1 V or a current

output of 4-20 or 0-20 mA are available to drive an external device such as a chart recorder. The analyzer can drive a proportional dosing pump through the 4-20 mA output, for chlorine or for

acid/alkali dosing.

PCA340 has two current outputs of 4-20 or 0-20 mA are available to drive external devices such as

chart recorders. The analyzer can drive two dosing pumps through the 4-20 mA outputs for chlorine and for

acid/alkali dosing. The analog output is fully programmable and could be proportional with chlorine concentration, pH,

ORP or temperature value. The limits of the analog output is selectable for each parameter. The analyzer can store up to 3500 readings (at least 7 days at 3 minutes sampling interval), that are

available for consulting or downloading. The PCA310 - PCA340 analyzers can be monitored or controlled through RS485 or GSM network

connection. Errors, alarms and warnings are sent through SMS (using GSM module HI504900). The analyzer state can be interrogated by a simple call using GSM phone.

GENERAL DESCRIPTION

Time is displayed on the main panel and a time related warning system for “Old calibration”, “Reagent expired” and “SIM expired” is available.

CHLORINE MEASUREMENT

Referring to the drawing on page 11 and the Fluidic Diagram on page 18, the Sample Line is connected to the instrument at the Sample Port (#17); an internal Regulator (#14) reduces the inlet pressure from a maximum of 4 bar (57.2 psi) down to 1 bar (14.3 psi); from the Regulator a nylon tube is connected to the input of the Electrovalve (#21). The output of the valve goes to the Drain Port (#11) and then to the Measuring Cell (#8). An optional Filter can be installed to the sample port if the stream is excessively turbid.

The sample coming from the line normally flows through the Measuring Cell (#8). It goes out from the Measuring Cell through the Drain Tube (#9) and the Output Port (#10).

The Measuring Cell is accessible from the port placed on the top (#7) for speedy cleaning and maintenance.

During the 100 seconds preceding the sampling, the analyzer solenoid input valve is open to allow sample flow to flush the colorimeter cell. Every 3 to 90 minutes (user selectable), the electrovalve closes stopping the sample flow and leaving the sample cell full of fresh sample. Cell volume is controlled by an overflow gateway.

As the sample inlet electrovalve closes, a series of measurements (with LED on and off) of the unreacted sample is taken to determine an average blank level prior to reagent addition.

The measurement of sample blank signal permits compensation for any turbidity or natural color, and provides the zero reference point for the measurement.

The two channel Peristaltic Pump (#5) starts rotating causing a precise quantity of buffer and indicator (#15 and #16) to enter the colorimeter sample cell. Here a magnetically coupled stirrer mixes the reagents with the sample.

115 VAC ± 10% or 230 VAC ± 10%; 50-60 Hz; 20 VA

OPERATING DESCRIPTION

After a delay for the color development, a series of measurements (with LED on and off) are taken (sample level) to determine an average chlorine concentration measurement. The reacted sample signal is then measured and displayed.

This sequence is repeated every 3 to 90 minutes (user-selectable).

METHOD OF ANALYSIS

Free available chlorine oxidizes the DPD indicator reagent at a pH between 5.5 and

6.0 to form a magenta-colored compound. The intensity of the resulting color is proportional to the concentration of chlorine in the

OPERATING DESCRIPTION

sample. The purpose of the buffer solution is to maintain the proper pH.

To measure total residual chlorine (free available chlorine plus combined chlorine) the PCA adds potassium iodide. The chloramines in the sample cause iodide ions to become iodine which then act with free chlorine to oxidize the DPD indicator. After the chemical reaction is complete, the optical signal at 555 nm is compared to the signal measured through the sample (before the reagents were added). From these measurements chlorine concentration is calculated.

pH AND TEMPERATURE MEASUREMENT

The HI1005 pH/temperature probe provides at the out port a potential proportional with the pH. The temperature is measured with Pt100 platinum sensor.

For increased accuracy the pH is corrected with temperature and with the calibration coefficients. Up to 2 buffers can be used for calibration.

The temperature can be displayed in °C or °F. The probe can withstand pressure up to 6 bar (87 psi).

ORP MEASUREMENT

The HI2008 probe provides at the out port a potential proportional with the ORP value. The value is directly displayed in mV. The probe can withstand pressure up to 6 bar (87 psi).

INSTALLATION PERSONNEL

Installation of the PCA310 - PCA340 Chlorine, pH, ORP and temperature analyzers should be undertaken by persons with technical knowledge of the dangers associated with chemical exposure and electrical shock.

Hanna Instruments assumes that persons performing the installation tasks are aware of the appropriate safety procedures.

CAUTION: Review the Material Safety Data Sheets (MSDS) before handling the supplied chemical reagents.

LOCATION OF THE INSTRUMENT Analyzer Location

Locate the analyzer as close as is reasonably possible to the point where the sample is withdrawn from the product stream (referred to as the sampling point).

The instrument should be mounted indoors, out of direct sunlight. Instrument operating temperature is 5 to 40 °C (41 to 104 °F).

Sampling Point Location

Locate the sampling point to obtain a truly representative sample from the product stream. For example, be sure the sampling point is well downstream from a Chlorine and acid/alkali feed. This assures that adequate mixing and reaction of the Chlorine and acid/alkali before a sample is extracted.

HYDRAULIC CONNECTIONS

Note: Hydraulic connections should be installed only by qualified personnel to assure conformity to applicable plumbing codes.

INITIAL PREPARATION AND INSTALLATION

Sample Line Installation

Direct routing of sample lines is recommended. If the large process pipes are horizontal, taps should be inserted vertically in the middle of the pipe to

avoid pulling sediment from the bottom or air bubbles from the top of the pipe into the sam ple line.

WARNING IFANY CONDENSED HUMIDITY IS FOUND INSIDE THE CASE PLEASE CONTACTYOUR VENDOR OR HANNACUSTOMER SERVICE.

A 1/2 BSP sample input fitting allows direct connection to the optional input filter. Sample line pressure should be between 0.07 and 4 bar (1 and 57.2 psi) with an ideal pressure of

0.7 bar (10 psi). It is recommended to assure that the water inlet come at 1 m above the instrument sample input

pitting. For maintenance issues is also recommended to install valves on both sampling pipes.

INITIAL PREPARATION AND INSTALLATION

Drain Line Installation

The drain hose fitting is a 20 mm (3/4”) hose barb on the bottom of the instrument enclosure. An air gap between the end of the drain hose and the drain is recommended to prevent any back flow into the instrument in the event of drain blockage.

Return Line Installation

The return hose fitting is a 12 mm (1/2”) hose barb on the bottom of the regulator output port and should always be connected even when pressure is below 1 bar.

INSTALLING THE INPUT FILTER

In order to ensure maximum accuracy of measurements, it is recommended to have always clear sample, with suspended particles smaller than 0.5 µm. This can be achieved by installing two filters before the sample input.

The type of filters depends on the quality of the water: the first filter should have 50-100 µm pore size, whereas in any case the second filter, the one closer to the analyzer, has to be 0.5 µm.

For correct instaling procedure and maintenance, see the instructions of filters.

INSTALLING THE pH AND ORP PROBES

To mount the pH and ORP probes, first turn off the analyzer. Unscrew the closing caps from the electrode holder and remove the protective cap from electrodes and

electrodes connectors.

INITIAL PREPARATION AND INSTALLATION

WARNING IFANY CONDENSED HUMIDITYIS FOUND INSIDE THE CASE PLEASE CONTACTYOUR VENDOR OR HANNACUSTOMER SERVICE.

WARNING IFANY CONDENSED HUMIDITY IS FOUND INSIDE THE CASE PLEASE CONTACTYOUR VENDOR OR HANNACUSTOMER SERVICE.

Screw the pH probe (HI1005) in the lower position and the ORP probe (HI2008) in the higher position and assure that no leakage occurs.

Only after the probe is in final position connect the probe to the dedicated connector. Lock the connector with the built in nut.

Warning: Never connect or disconnect the probes when the analyzer is powered on.

INSTALLING THE PUMP TUBES

Locate the analyzer reagent tubes in the accessory kit. Each tube is composed of three sections. The sections are joined together by plastic connectors with plastic collars at the ends of the center section.

Locate the peristaltic pump.

INITIAL PREPARATION AND INSTALLATION

Feed one tube from the shorter end section behind the pump rollers from the right side of the pump. Seat the plastic collar at the right end of the center section of tubing into the lower right indentation hole of the pump face.

Grasp the other plastic collar and pull, stretching the center section, and place the grommet in the lower left indentation hole.

Repeat this process with the second pump tube, placing it in the upper indentation holes. Separate reagent caps are provided in the accessory kit. Put the supplied caps onto each reagent

bottle prior to installing them.

Place the indicator bottle (HI70450 for free chlorine and HI70460 for total chlorine) on the right and the buffer bottle (HI70451 for free chlorine and HI70461 for total chlorine) on the left.

Note: Add the content of 5 HI70452 sachets, DPD Compound, to the Indicator Solution prior to installing it.

Connect the longer tube ends on the left side of the pump to the reagent bottle cap insert fitting. Connect the short ends in the right side of the pump to the measuring cell reagent input port through

the “Y” connector.

INITIAL PREPARATION AND INSTALLATION

ELECTRICAL CONNECTIONS

A power cable (3 mt.) is provided with your analyzer. However, if access to the terminal block is required, see below.

Warning: Electrical connections should be installed only by qualified personnel to assure conformity to applicable electrical codes.

Unplug the meter before any electrical connection.

230 VAC (50 Hz)

Power Connection

Power connections are made at a terminal block located in the center of the electrical compartment to the right of the fuses.
