Material Safety

GENERAL DESCRIPTION

The Hanna PCA 310, PCA 320 and PCA 330 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 PCA 310-330 monitor the free chlorine or total chlorine in the 0 to 5 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 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.

PCA 320 and PCA 330 analyzers HI 1005 probe to continuously measure the pH of the sample stream in the range of 0 to 14 pH. The sample temperature is measured in the 5 to 75°C range. pH and temperature are displayed on the front panel. pH value is corrected with temperature.

PCA 330 analyzer use HI 2008 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 PCA 310-330 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/delta) is user selectable with a delta between 0.1 and 5 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/delta) is user selectable with a delta between 0.1 and 2 pH . The on/off dosing hysteresis is user selectable between 0.05 and 2.00 pH. 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. 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 chloride and for acid/alkali dosing. The analog output is fully programmable and could be propor-

tional 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

OPERATING DESCRIPTION

CHLORINE MEASUREMENT

Referring to the drawing on page 10 and the Fluidic Diagram on page 17, the Sample Line is connected to the instrument at the Sample Port (#17); an internal Regulator (#15) 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 (#7). 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 (#7). It goes out from the Measuring Cell through the Drain Tube (#8) and the Output Port (#9).

The Measuring Cell is accessible from the port placed on the top (#6) 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 (#13 and #16) to enter the colorimeter sample cell. Here a magnetically coupled stirrer mixes the reagents with the sample.

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 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 HI 1005 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 HI 2008 probe provides at the out port a potential propor- tional with the ORP value. The value is directly displayed in mV.

The probe can withstand pressure up to 6 bar (87 psi).

INITIAL PREPARATION AND INSTALLATION

INSTALLATION PERSONNEL

Installation of the PCA 310-330 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 han-

dling 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.

Sample Line Installation

Direct routing of sample lines is recommended. If the large process pipes are horizontal, taps should be in-

serted 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 sample line.

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.

WATER OUTLET

WATER INLET

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 installing procedure and maintenance, see the instructions of filters.

INSTALLING THE pH AND ORP PROBES

To mount the pH and ORP probes, first tunr off the analyzer. Unscrew the closing caps from the electrode holder and remove

the protective cap from electrodes and electrodes connectors.

A system error feature provides relay activation to signal the need for operator intervention through an external device, such as a buzzer, a light or any other electrical equipment. When errors appears, the relay is closed (Common connect to Normal Close).

The SYSERR LED blinks when a system error occurred. If the situation persists for more than a few samples, the op-

erator should notify maintenance personnel for investigation of the problem.

Note: When the meter is in alarm mode or in system error mode, the

user could directly view the alarm or error description on the display.

If GSM transmitter is installed and GSM mode is selected, the alarms and errors are sent as SMS message.

The System error relay is power-fail safe and is closed when the analyzer is not powered.

Chlorine Dosing Relay

The chlorine dosing relay is activated (Common connected to Normal Open) when chlorine concentration is under the dosing setpoint. The chlorine dosing use a proportional algorithm that depends on both, setpoint and delta.

The DOSING CHLORINE LED is turned on when the dosing relay is closed.

Note: The chlorine dosing is stopped when the concentration is over

Alarm high setpoint or when a System error related to chlorine measurement occurs.

Acid/alk dosing relay is activated (Common connected to Normal Open) depending on the setpoint and selected delta. If the analyzer is set to dose acid, the relay is active when the pH value is over the setpoint. If alkaline is dosed, the relay is activated when the pH value is under the setpoint.

The DOSING ACID/ALK. LED is turned on when the dosing relay is closed.

Note: The acid/alk dosing is stopped when system error related to

pH occurs.

Recorder Outputs

The recommended recorder hookup uses a twisted pair shielded cable. The shield should be connected to the terminal at the instrument end and left open at the recorder end.

To operate with this hookup, the following conditions are required at the recorder end:

• The input to the recorder must be isolated from the chassis ground (earth) of the recorder;

• If the recorder has more than one input, they must be differential inputs.

Two types of outputs are available: 0-20 mA or 4-20 mA for each output. The recorder outputs could be assigned to Cl, pH, Temperature or ORP.

Proportional dosing pump

Two proportional dosing pumps could be connected to the 4-20 mA outputs. The pump could be used to dose chlorine and acid/alk as selected by the user. When the output is 4 mA, the pump must be stopped and when the output is 20 mA, the pump must provide the maximum output.

RS485

The analyzer has RS485 serial communication with selectable baud rate between 1200 and 9600 Bps. The GSM module HI 504900 is also connected using the RS485 port.

Note: The RS485 could use also the ground wire to

prevent common mode voltages.

STARTUP

To power up the analyzer open the electronic box door and turn on the main switch.

When the analyzer is powered up, the display backlight is turned on and the initialization take place. In this phase, the integrity of the stored data is checked and the information regarding the language is loaded.

The display will show HANNA INSTRUMENTS, the name of the instrument and the software version.

Note: If the instrument is set for free chlorine analysis, the software

will report at startup Free Chlorine and if it is set for total chlorine, the software will report at startup Total Chlorine.

After initialization, the analyzer will show the main panel (or chlorine measuring panel for PCA 310). The measured value are displayed. The chlorine concentration will be updated only after a full measuring cycle. The first reading is 0.00 mg/L and the dosing relay is not active.

After the first chlorine concentration is measured and displayed, the chlorine dosing relay is activated if necessary.

Note: If the SMS feature is selected and correctly configured, the

analyzer will send a SMS at each power up sequence.

MEASURE INFO

ANALOG OUTPUT

Select “Chlorine Menu” - “Measure Settings” and set the “Period” between 3 and 90 minutes.

Period (sampling rate) is the elapsed time between two consecutive chlorine measurements. The sampling rate is also important when the analyzer is used for chlorine dosing. For larger pools, the period must be longer, and for smaller pools, the period must be shorter.

The sampling rate can be quickly consulted on one chlorine measuring panel.

The analyzer calculates the maximum and minimum concentration value since the first measurement.

The maximum and minimum can be quickly consulted on chlorine measuring panel.

To see information about these values, select “Chlorine Menu”

- “Measure Info”. The time stamp when maximum and minimum appears are also displayed in this menu.

To reset the maximum or minimum values, select the functions “Chlorine Menu” “Measure Info” “Clear Max. Value” or “Chlorine Menu” “Measure Info” “Clear Min. Value”.

The maximum or minimum value will be set to the current read value.

The type of analog output can be set as described in “Analog output” chapter. The analog output span for chlorine could be set in “Chlorine Menu” - “Analog Output Cl”.

“Min. Rec” will set the recorder lower limit and “Max. Rec” will set the recorder higher limit. The Max. Rec. value must be greater than Min. Rec. value.

Note: The speed of the analyzer could be modified by changing the

sampling rate. A new decision regarding the chlorine regulator is taken only after a new measurement.

The Setpoint and Delta could be quickly consulted on one chlorine measuring panel.

LOW READING PROTECTION

To prevent excessive chlorine dosing if the detector is not working properly or the reagent bottle is empty, a “Detector Error” is generated if the measured chlorine value is under the low point value. This error is generated only if the low point feature is set active.

The chlorine dosing is stopped and the SYSTEM ERROR LED starts blinking.

To enable this feature, edit “Chlorine Menu” - “Dosing control Cl” - “Low Point” value and set the “Low Point” status as “Active”. The allowed value is 0.00 to 1.00 mg/L.

OVERDOSING PROTECTION

To prevent overdosing a “Detector Error” is generated if the dosing command is on for the Max. ON time and the read value is changing less than 0.05 mg/L.

The chlorine dosing is stopped and the SYSTEM ERROR LED starts blinking. The dosing could be resumed only by restarting the controller.

To modify this protection, edit “Chlorine Menu” - “Dosing control Cl” - “Max. ON” value. The allowed range is between 30 and 720 minutes.

ALARMS

Two alarm setpoints are available for chlorine: Alarm high and Alarm low.

The ALARM LED and alarm relay are activated when the chlorine concentration is higher than Alarm high or lower than Alarm low.

To modify the alarm setpoints, enter the “Chlorine Menu” “Alarms Chlorine” and edit “Alarm Hi” or “Alarm Lo” value.

The alarms could be separately activated or inactivated. To modify the alarms status, enter the “Chlorine Menu” - “Alarms

Chlorine” menu and edit “Alarm Hi” or “Alarm Lo” status. When the status is set to “Inactive”, the alarm is ignored.

Note: The Alarm high must be greater than Alarm low value. The

analyzer display a warning if the settings are incorrect. The Alarm high setpoint and Alarm low setpoint could be quickly

consulted on one chlorine measuring panel. When an alarm is disabled, the —.— is displayed instead of alarm value.

CALIBRATE THE MEASURING CELL

The PCA 310-330 analyzers have the possibility to calibrate the measuring cell.

When a new calibration is performed, calibration factor is recalculated and all measurements are multiplied with it.

CALIBRATION DATE AND FACTOR

The last calibration date can be found in the “Chlorine menu” “Cal. Measuring Cell”

- “Cal. Date”. Calibration date is in the YY / MM / DD format.

A warning “Cl Calibration Old” is displayed if one month elapsed from the last calibration.

The calibrated date is updated after a new calibration is done. The calibration factor is displayed in “Chlorine menu” - “Cal.

Measuring Cell” - “Factor”. The default calibration factor is 1.000. Each measurement

result is multiplied with calibration factor. The calibration factor could be reset to 1.000 by activating

the “Chlorine menu” - “Cal. Measuring Cell” - “Reset Cal. Factor” function.

CALIBRATION PROCEDURE

To calibrate the measuring cell, follow the steps:

• Withdraw a sample of the measured liquid directly from the drain port of the measuring cell (#11) by opening its valve (#10) - see figure on page 10.

Note: Withdraw the sample just before the electrovalve stops the liq-

uid flow to the measuring cell.

Cal.Value:0.14 mg/L

Factor :0.954

Cal. Date:04/01/20 Reset Cal. Factor

Calibration Blank

• With a calibrated meter take a measure of the sample. This is the calibration value.

• Wait for the PCA to display the new reading.

• Go in “Chlorine menu” - “Cal. Measuring Cell” and edit “Cal. Value” field.

• Enter the calibration value and save with “CFM”.

• The calibration coefficient and the calibration date will be updated.

• Press repeatedly “ESC” to exit from menu mode. The displayed chlorine concentration will be equal with the calibration value.

Note: It is not recommended to calibrate the analyzer at values below

2 mg/L in order to maintain enough accuracy in the whole range. Calibration below 2 mg/L does not guarantee declared accuracy outside an interval of ±50% from the calibration value.

pH SETTINGS (PCA 320, PCA 330)

Settings related to pH measurement are grouped in “pH Menu”. The following options are available:

MEASURE INFO

The analyzer calculates the maximum and minimum pH value since the first measurement.

The maximum and minimum can be quickly consulted on one pH measuring panel.

ANALOG OUTPUT

pH DOSING

PROPORTIONAL DOSING

The type of analog output could be set as described in “Analog output” chapter. The analog output span for pH could be set in “pH Menu” - “Analog Output pH”.

“Min. Rec” will set the recorder low limit and “Max. Rec” will set the recorder high limit. The Max. Rec. value must be greater than Min. Rec. value.

The output will be proportional with pH value if the read value is between those limits.

The analog output limits could be quickly consulted in one of the pH measuring panel.

The PCA 320 and PCA 330 can use ON/OFF or proportional dosing algorithm to stabilize the pH .

The analyzer has a relay for acid or alkali dosing and also the 4-20 mA output could be configured as a dosing output.

To select the type of pH dosing edit the “pH Menu” - “Dosing Control pH” - “pH Control” line. The available options are Proportional and

pH Control:On/Off

Dosing Type:Acid

Period :003 sec Setpoint :07.00 pH

Delta :0.1 Hysteresis:1.00 pH Max. ON :060 min

ON/OFF. The acid or alkali dosing is set in the “pH Menu” - “Dosing

Control pH” - “Dosing Type”. When “Acid” is selected, the analyzer will dose when the pH value is higher than the setpoint and when “Alk” is selected, the analyzer will dose when the pH value is lower than the setpoint.

The proportional dosing algorithm turns on the dosing relay proportion-

time

The equation for determining the time for relay on is: dosing time = (set value - measured value)*Period/Delta

The analog output will have the value: analog output [mA] = 4 + 16 * dosing time/Period [mA]

Note: If the measured pH is lower (or higher for acid dosing) than

setpoint minus (plus) delta, the dosing will be continuous until the pH period elapsed.

To modify the dosing setpoint, enter the “pH Menu” - “Dosing Control pH” edit the “Setpoint” line. The value must be between 2.00 and 12.00 pH.

To modify the Delta, edit the “Delta” line. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.5, 2.

To modify the dosing time edit the “Period” line. The allowed values are between 3 and 120 seconds.

Note: The period is related only to the dosing process. The pH mea-

surement take place with a higher rate.

Note: The speed of the analyzer could be modified by changing the

regulator period. A new decision regarding the pH dosing is taken only after one period elapsed.

The Setpoint and Delta could be quickly consulted on one pH measuring panel.

ON/OFF DOSING

If this mode is selected the Period and Delta has no effect. The algorithm will use only Setpoint and Hysteresis.

For alkaline dosing, the relay will stay on until the pH increases to the setpoint plus hysteresis value, then the relay stays off until the pH decreases to a value equal to setpoint.

For acid dosing, the relay will stay on until the pH decreases to the setpoint minus hysteresis value, then the relay stays off until the pH increases to a value equal to setpoint.

To set the hysteresis edit the “pH Menu” - “Dosing Control pH” - “Hysteresis” line. The hysteresis value must be between

0.05 and 2.00 pH.

OVERDOSING PROTECTION

To prevent overdosing a “Detector Error” is generated if the dosing command is on for the Max. ON time and the read value is changing less than 0.1 pH.

The acid/alkali dosing is stopped and the SYSTEM ERROR LED starts blinking. The dosing could be resumed only by restarting the controller.

Note: The Alarm high value must be greater than Alarm low value.

The analyzer display a warning if the settings are incorrect. The Alarm high Setpoint and Alarm low setpoint could be quickly

consulted on one pH measuring panel. When an alarm is disabled, the —.— is displayed instead of alarm value.

pH CALIBRATION (PCA 320, PCA 330)

It is recommended to perform pH calibration when the probe is replaced and after any cleaning action.

The analyzer can perform 2 points calibration, 1 point calibration or process pH calibration.

To perform any pH calibration enter in “pH Menu” - “Cal. pH Probe”.

Initial Preparation

Set Default pH Cal.

Process pH Cal.

Buffer pH Cal. Cal. Date :01/01/01

In this menu the last calibration date is displayed on the “Cal. Date” line. If the probe calibration is older than 1 month, a warning is displayed.

Pour small quantities of pH 7.01 (HI 7007) and pH 4.01 (HI 7004) or 10.01 (HI 7010) solutions into individual beakers. If possible, use plastic beakers to minimize any EMC interference. Also NIST buffers of 6.86 or 9.18 could be used.

For accurate calibration use two different beakers for each buffer solution, the first one for rinsing the probe and the second one for calibration. By doing this, contamination between buffers is minimized.

Unscrew the probe from its position. Take care to stop the sample flow before removing the probe. If necessary, disconnect the probe from analyzer to prevent the damage of the

probe cable.

ONE POINT CALIBRATION

Immerse the pH probe into the buffer solution (e.g. pH 7.01) until the metal ring is immersed, then stir gently.

Select the “pH Menu” - “Cal. pH Probe” - “Buffer pH Cal.”.

• The analyzer will prompt to select the first buffer. Select the buffer (e.g. pH 7.01) using “UP” or ”DOWN” arrow keys and confirm.

• The analyzer checks for readings stability. During this period, the “Wait for stabilize” message is displayed.

Note: If the read value, calculated with the default offset and slope, is

different from the expected value with more than 1.15 pH (i.e. offset > 68mV), the “Wrong calib. values” message is displayed.

The message “Wrong calib. values” appears also if the pH probe is defective or not connected. The problem could be identified if the buffer set value is compared with the actual read value (first and second line of the display).

If the probe is inserted in the appropriate buffer, the measuring cycle is restarted automatically and message “Wait for stabilize” is displayed again.

• If the temperature reading is wrong, the value is set to 25 °C and a blinking “*” is displayed near it, indicating that is not the real temperature value. The calibration procedure is not interrupted.

• When the reading become stable, the analyzer displays “Stable... press CFM”.

Buffer 1 pH: 7.01

Measured pH: 7.02

Temp. [ºC]: 25.1 Wait for stabilize

• The analyzer prompts for the second buffer selection, and displays the message “Select buffer pH... or press SET for one point cal.”.

Pressing “SET” key will end the one point calibration procedure.

TWO-POINTS CALIBRATION

• To perform a two-points pH calibration follow the steps de-

scribed at one-point calibration until the analyzer displays the message: “Select buffer pH... or press SET for one point cal.”.

• Immerse the pH electrode into the second buffer

solution (e.g. pH 4.01) until the metal ring is immersed, then stir gently.

• Press “UP” or “DOWN” arrow keys to select the second buffer from the list to continue the calibration and confirm with “CFM”.

Note: The difference between the first and second buffer must be

more than 1 pH in order to assure the calibration accuracy. Calibration using 7.01 and 6.86 pH or 10.01 and 9.18 pH is not allowed.

• The analyzer checks for readings stability. During this period, the “Wait for stabilize” message is displayed.

• When the reading becomes stable, the instrument checks if the calculated slope is between 47.3 and 68 mV/pH. If the value is not within this range, the message “Wrong calib. values” is displayed. In this case it is necessary to perform a cleaning procedure (see “Electrode conditioning and maintenance” section) or to replace the probe.

• If the value is accepted, the analyzer displays “Stable... press CFM”.

Pressing CFM, the two point calibration is completed.

PROCESS pH CALIBRATION

The PCA 320 and PCA 330 has the possibility to calibrate the pH probe without using buffers and without dismount the probe. For doing this calibration, a reference pH-meter must be used. To complete the process calibration, follow the steps:

Probe

pH 4.01

• Pour a quantity of sample in a beaker. Use the sample of the measured liquid directly from the drain port of the measuring cell (#11) by opening it’s valve (#10) to do this as described in the Calibration Procedure chapter.

• Place the pH probe of the reference meter in the beaker and stir gently.

• Wait for readings to stabilize.

• Enter in “pH Menu”- “Cal. pH Probe” - “Process pH Cal.” and enter in the “Cal. Value” field the reading from the reference pH meter.

• Press “CFM” key when the analyzer prompt for “Overwrite pH cal. ?”.

•The analyzer checks for readings stability (see One-point calibration) and when the value is stable the message “Stable... press CFM” is displayed.

• Pressing “CFM” key will complete the process pH calibration.

Note: The calibration could be terminated at any time by pressing

“ESC”. In this case the new calibration is not saved and the old one remains effective.

SET DEFAULT CALIBRATION

When a new probe is connected or for any reason the current calibration is wrong and new calibration can’t be performed, the default calibration values could be set. In this case the slope is set to 59.16 mV/pH and the offset is set to 0 mV.

To accomplish that, select “pH Menu” - “Cal. pH Probe” “Set Default pH Cal.”

The analyzer will ask “Reset the pH cal. to default ?” and if “CFM” key is pressed will replace the existing calibration coefficients with the default values.

Cal. Value:06.84 pH

TEMPERATURE SETTINGS (PCA 320, PCA 330)

Settings related to temperature measurement are grouped in “Temperature Menu”. The following options are available:

UNITS

The analyzer could display the Temperature using Celsius or Fahrenheit temperature units.

To select the temperature units, edit the “Temperature Menu” “Units” line. Select Celsius or Fahrenheit and confirm.

ANALOG OUTPUTS

The PCA 310-330 analyzers has two current analog outputs. Each one can be configured as 0-20 mA, 4-20 mA or dosing type. Also they can be assigned to one of the measurement parameters: Cl, pH, Orp, Temp.

SELECT THE ANALOG OUTPUT TYPE

To select the analog output type enter in “General Menu” “Analog Output1” or “Analog Output2”. The analog output could be assigned to one of the four measured parameters. To define this assignment, edit the “Out Param.” field. “Chlorine”, “pH”, “ORP” and “Temper.” options are available. To select the analog output type edit the “Type” line. The available options are: 0-20 mA , 4-20 mA current outputs.

DOSING THROUGH 4-20 mA OUTPUT

Select “General Menu” - “Analog Output1” or “Analog Output2” - “Type” as Dosing to activate this feature. The output become 4-20 mA current type, proportional with pH or chlorine regulator output. The 4 mA correspond with pump stop and 20 mA correspond to pump operating at full speed. This mode should be selected when a proportional pump is attached to the analyzer.

Note: In this mode calibration is not allowed. If calibration menu is

entered, the following message appears: “Analog output value cannot be changed when analog output type is dosing”.

Out Param.:Chlorine

CALIBRATE THE ANALOG OUTPUTS

The analog output is factory calibrated. Recalibration is not needed when the output type is changed.

If, for any reason, a new calibration has to be performed, each output type could be easily calibrated.

To calibrate the current type analog outputs, follow the steps:

• Connect an ammeter to the pin 1 and 2 /

pin 3 and 2 of the output connector.

• Enter in menu mode and select “General

Menu” - “Analog Output” sub-menu.

• Select the analog output type to one current

type 0-20mA or 4-20 mA.

• Select “Cal. Analog Out Max” and press “Up” and “Down”

keys until the read value is equal with 20 mA.

• Save the new coefficients by pressing “CFM” key.

• Select “Cal. Analog Out Min” and press “Up” and

“Down” keys until the read value is equal with 0mA or 4 mA. The analog output source current and when calibrating 0mA, a positive value must be set for current (0.1mA for example) and then the current must be slowly decreased to 0mA.

• Save the new coefficients by pressing “CFM” key.

Note: The analog output calibration is not allowed if the analog

output type is set to “Dosing”. Pressing for longer time the arrow keys will increase the variation

speed of the analog output.

OUTPUT MIDDLE RANGE

To easily adjust a recorder offset, the analog output could be set to middle range. In this case the output is set to 12 mA or 10 mA for 4-20 mA or 0-20 mA output.

To activate this option select “General Menu” - “Analog Output1” or “Analog Output2” - “Output Middle Range” function and press “CFM” key. The analyzer will display “Recorder output is set to middle value”. Press “ESC” to exit from this function.

VIEW LOG

The PCA 310-330 analyzers have a permanent logging function. Up to 3500 records could be stored. At a sampling interval of 3 minutes the log covers more than 7 days.

If the logging memory is full, the oldest record is lost when a new record is stored.

The record contains the date and time, the chlorine, pH, ORP and temperature value and the status of errors and alarms.

The data are stored after the chlorine measuring cycle is completed. The log could be performed only after several chlorine cycle. The number of cycles between two logs are set in “General Menu” - “System Log” - “Log Cl cycles”.

The allowed range is between 1 and 10 chlorine measuring cycles.

log Cl cycles is set to 5, a new record is stored at each 15 minutes (3 x 5).

To erase the system log activate the function “General Menu”

- “System Log” - “Clear System Log”.

To consult the log, select “General Menu” - “System Log”. The searching criteria for viewing the log could be set by

editing the “Search” field. The following options are available:

SERIAL COMMUNICATION

The PCA 310-330 have one RS485 serial communication port. The serial communication is galvanically isolated from other analyzer parts.

The connector configuration for RS485 is shown in the figure aside.

Two mode of working are available for the serial communication: STANDARD and GSM.

STANDARD MODE

The analyzer could be connected to PC using RS485 to RS232 converter. With the HI 92500 software the analyzer data could be downloaded to the PC and also the analyzer parameters could be set from PC.

To set communication as PC type, select “General Menu” “Serial & GSM Comm.” and set the “Type” to STANDARD.

To establish connection with the PC the baud rate, the RS485 address and the password must be matched between the application and PCA 310-330 analyzer.

The baud rate is set in the “General Menu” - “Serial & GSM Comm.” - “Baud Rate” menu. Available values are 1200, 2400, 4800, 9600 bps.

Analyzer address is set in the “Address” line and could be between 0 and 32.

Note: If many analyzers are connected in a RS485 network, each

analyzer must have a unique address.

Note: While one parameter is edited by the user the PC software is

unable to modify it. Any other parameter could be modified by the PC software.

RS 485

GSM

GSM MODE

If the “Type” is set to GSM, the analyzer will work with HI 504900 GSM module. This connection enables the analyzer to send SMSs to one (or two) cellular phone(s) and through this feature the device can be monitored. Moreover if an error occurs on the PCA 3x0, a SMS is sent to the cellular phone(s) signaling immediately the user about the problem.

When the SMS feature is active, three type of SMS messages are sent to the selected cellular phone(s).

Alarm SMS which contains the Error, Alarm and Warning messages

that are active on the analyzer, separated by ‘;’. The events that generate the alarm SMS are user selectable from “General Menu” - “SMS Settings”.

Info SMS which contains the Chlorine, pH, ORP and Temperature read-

ings. Analyzer’s error status and settings are also included as selected by the user from “General Menu” - “SMS Settings”.

Warning SMS which contains information about the SIM card credit.

The settings related to GSM are grouped in “General Menu”

- “Serial & GSM Comm.”.

SETTING THE GSM FEATURE

To use the SMS feature, a SIM card able to make voice calls must be used.

It is necessary to enter the PIN code of the SIM card inserted in the GSM module. To do this, set the “General Menu” - “Serial & GSM Comm” “PIN No.”.

Note: The PIN number is not

visible after editing for protection reasons. The field will always show 0000.

39123456789.

The numbers could be activated or inactivated. The SMS is sent only to active numbers. If both numbers are inactive, no SMS is sent even if both numbers are correctly entered. To activate the phone numbers, set “Active” in the “Phone1” and “Phone2” fields.

The SMS sending has to be activated by selecting “Active” in the “Send SMS” field. If “Send SMS” is set to “Inactive” then no SMS will be sent even if the phone numbers are active.

The number of repeated alarm SMSs could be set in the field “RepeatNo”. The range is between 0 and 5. If RepeatNo is set to 0 than only one SMS is sent.

The delay between two repeated SMSs is set in the “Delay” item. The range is between 5 and 60 minutes. If the “RepeatNo” is 0, this parameter has no effect.

After the correct settings are done, the SMS feature can be enabled by set “General Menu” - “Serial & GSM Comm.” “Type” to GSM.

wrong PIN, then no other attempt will be allowed (prevention of sending three wrong PINs).

To make another attempt, a new PIN has to be entered and the analyzer has to be restarted. The analyzer attempt to initialize the GSM module at startup.

If a wrong PIN was entered three times, the user has to extract the SIM card and manually enter the PUK number using his own cellular phone to unlock the SIM card.

Note: There is no need to modify the default baud rate (1200) of the

serial link when enable the GSM feature. It will be switched to 9600 automatically.

SETTING SMS FEATURE

In order to avoid the frequent sending of the SMSs or rapid consuming of the GSM credit when one measuring channel not work correctly, the SMS sending could be customized.

The options are available in the “General Menu” - “SMS Settings”.

To select the events that generate alarm SMS, set the “Cl Events”, “pH Events”, “ORP Events” or “Temp. Event” as Active or Inactive. When one of them is active the corresponding alarms and errors will generate an alarm SMS. When alarm SMS is sent, all current alarms and errors are sent, even if are not the ones that initiate the SMS.

To customize the info SMS, two options are available:

• “Errors” - when active will include in the info SMS all alarms and errors currently active on the analyzer.

• “Set” - when active will include in the info SMS alarm and dosing setpoints.

Alarm SMS

When errors or alarms appears, alarm SMS is sent to the active phone numbers. Alarm SMS is sent without special request. The events that generate alarm SMS could be selected as described in Setting SMS Feature paragraph. Alarm SMS is sent once per chlorine cycle.

At each sending of alarm SMS, after 30 seconds, a phone call is made by the analyzer to the programmed number(s). This is done because the SMS can be received with a considerable delay due to network overload, while the phone call takes place immediately and has a long ring which is more likely to be heard.

--Alarms SMS--

Cl Events :Inactive

pH Events :Inactive ORP Events:Inactive

Temp.Event:Inactive

--Info SMS --

Set :Inactive Errors :Inactive

Info SMS

The phone call advises the user that something happened on the PCA analyzer and SMS is going to be received. Is not necessary to answer the phone call and it is suggested to close it without any answer.

A confirmation of the alarm message reception is waited by the analyzer. The confirmation can be done by simply calling the PCA analyzer phone number (number of the GSM module). The analyzer will hang up without answering and will send Info SMS (this confirmation is managed as an information request; see further on for details). Info SMS don’t need confirmation.

If “RepeatNo” is more than 0, the instrument sends repeated (1 to 5 times) alarm messages if confirmation is not received. This feature prevent losing of the message due for example to overload of the telephone network. The “0” is associated with no repetition: only one message will be sent and no confirmation waited.

The delay (5 to 60 minutes) between two subsequent repeated messages could be set on the “Delay” line.

Note: A remote connection will cancel the confirmation waiting. Also,

the analyzer events occurred during a remote connection will not generate any alarm SMS, even after the remote connection ends.

Example of alarm SMS: “Temp Err;L Ph;H Temp;Pwr rst;” (see Errors,

Alarms and Warnings chapter for details).

When the instrument receives a phone call (coming from one of the programmed cellular numbers), it interprets the calling as an information request and reacts hanging up and sending an info SMS.

The maximum number of characters for an SMS is 160, so, if the message text is longer, many messages will be sent. In this case a message header is added with informations about the message type and the current / total number of SMSs (for example INF1/2: ).

It is possible to ask the PCA 310-330 for Info SMS from a cellular phone different from the one(s) set in the analyzer. This is accomplished by sending to the instrument the SMS: “PxxxxAWE”, where xxxx is the analyzer’s password (the one used for settings).

The instrument will recognize the command and reply sending the Info SMS.

Note: If the analyzer is waiting for confirmation after sending an

Example of info SMS:

Example of info SMS (splitted):

Warning SMS

alarm SMS, the received SMS will be just stored on the SIM until the confirmation is coming or all the repeated alarm SMSs are sent.

The info SMS will always contain the Chlorine, pH, ORP and Temperature readings and the Settings and Errors if enabled. Also, the remaining SMSs number will be added if “Chk. Charge” is active.

“Temp Err;L Ph;H Temp; READINGS: ReagRem=8413;Cl=2.05;

pH=7.02;Orp=700;Temp=25.2;”

“INF1/2: Temp Err;L Cl;L Ph;H Temp;Cl Cal;SET: Cl(SP=2.00; AIH=2.70;AIL=150);pH(SP=7.00;AIH=8.00;AIL=6.00);ORP (AIH=800; AIL=200);Temp(AIH=30.0;AIL=20.0);” “INF2/2: READINGS: ReagRem=8413;Cl=1.35;pH=5.02; ORP=280; Temp=75.0; Remaining SMS=321;”

The information about SIM charge and expiration date are not saved in the SIM card but are managed by the network operator; the analyzer can not get directly the information.

To prevent an unnoticed discharge of the SIM card, the user has to configure manually (accordingly with the credit stored on the SIM card), the maximum number of SMSs that can be sent. The item is “Remaining” (SMS) in the “General Menu” “Serial & GSM com.” menu.

If the “General Menu” - “Serial & GSM com.” - “Charge Inf”is set “Active”, every time an SMS is submitted, the “Remaining” item is updated and will always indicate the remaining number of messages that the analyzer can send.

With “Chk.Charge” set “Active”, the number of remaining SMS is checked and when is going to reach zero, a warning SMS containing the text “Maximum number of SMS reached. Please check the cellular SIM card charge level” is sent.

Charge Inf:Active

Exp.Date:2010/01/01

Remaining:0000

RepeatNo:2

This particular situation is managed as an error occurrence and a confirmation of the SMS reception is waited. After that, a “GSM no credit” warning appears on the display signaling that no other SMS can be sent.

In this case the user is supposed to extract the SIM card from the cellular module as soon as possible and check the remaining credit (using its own cellular phone and calling the network operator).

Every time a recharge of the cellular module SIM card is performed, the corresponding expiration date has to be manually updated – item “Exp.Date” in the “General Menu” - “Serial & GSM com.”.

If the “Chk.Charge” item is set “Active”, a check is performed daily between the current date and the expiration date. Two weeks before the expiration date, the warning SMS “The cellular SIM card will expire on: DD-MM-YYYY. Please recharge or substitute it” is sent to the programmed phone number(s). The same message will be sent again also one week before, and the day before the expiration date.

Note: This particular warning message does not need confirmation.

In this case the user has to recharge or substitute the SIM card. The sending of the repeated warning messages will be reset when the expiration date is changed. If the expiration date is reached without any updating of the expired date, then the message “GSM Card expired” appears on the display and no more SMSs will be sent by the analyzer until the error is deactivated.

To deactivate this error it is necessary to update the SIM expiration date.

If the user has unlimited credit on the SIM card, the “Chk. Charge” must be set “Inactive”. In this case the value of remaining messages will not be decremented and no check will be performed on the SIM card expiration date. Moreover, in the info SMS will not be present the remaining-messages information.

Note: If a problem related to GSM feature occurs during the normal

functioning of the analyzer, the “GSM Not Respond”, “GSM Init failed” or “GSM Network Error” will be displayed and the analyzer will try repeatedly to initialize the cellular engine. The error will be deactivated only after a successful initialization.

MODEM CONNECTION

Note: If the PC stops the communication for 4 minutes, the GSM

Modem connection can be established between PCA 310-330 and a remote computer. The connection allows the user to interrogate the analyzer, from remote position, about its status and measurements and to change analyzer parameters. Also the log could be downloaded through remote connection.

A SIM card able to receive data calls must be used in HI 504900 GSM module.

To enable the answer to data request, the item “Remote” from “General Menu” “Serial & GSM com.” must be set “Active”.

To make the data transfer between PCA 310-330 and remote PC, HI 92500 software must be installed on the PC, and modem must be connected between PC and phone line.

The baud rate, the password and the RS485 address must the same on PCA and on PC application.

MAINTENANCE

The PCA 310, PCA 320 and PCA 330 analyzers incorporate several technologies to minimize the maintenance.

Also, if the GSM module is connected, the warnings, alarms and errors are sent to the operator, making the maintenance even simpler.

The analyzer status could be sent via SMS messages after a call from operator.

Calibration of the chlorine measuring circuits is not normally required. The DPD technique for measuring chlorine concentration is well established and consistent. Also, by measuring the sample blank absorbency to establish the zero reference with each measurement, the accuracy of the analyzer is assured.

If, for any reason, the Chlorine measurements are inaccurate proceed with the calibration procedure.

A visual check of the hydraulic compartment can detect leaks, pump tubing fatigue or breakage. These periodic checks help ensure reliable analyzer performance.

PCA 310-330 analyzers warning the user when the reagents level reaches approximately 20% with the “Low reagent” message.

Working at maximum capacity (3 minutes sampling rate), the analyzers can operate for 1.5 more days.

The alarm system is based on an internal counter that has to be reset every time the reagents are replaced.

The counter keeps track of the number of measurements taken and informs the user when it reaches the 16000th sample with the message “No reagent”.

The pH, ORP and Temperature measurements are done with standard techniques that assure reliability and accuracy. However if a problem occurs on those measuring channels, an SMS is sent to the user.

Furthermore, if the relation between chlorine, pH and ORP is known for a certain application, one of those readings could be used to check the others, for example check the chlorine and pH by reading the ORP values.

ELECTRODE CONDITIONING AND MAINTENANCE

Preparation

Remove the probe protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with probes and they will disappear when rinsed

with water. During transport tiny bubbles of air may have formed inside

the glass bulb. The probe cannot function properly under these conditions. These bubbles can be removed by “shaking down” the probe as you would do with a glass thermometer. If the bulb and/or junction are dry, soak the probe in HI 70300 Storage Solution for at least one hour. If the probe does not respond to pH changes, electronics may

be down and the electrode should be replaced.

Test measurement

Rinse the probe tip with distilled water. Immerse the probe in the Hanna pH buffer 7.01 (HI 7007)

until the solution is in contact with the metal ring and stirr gently for 30 seconds. The reading must be near 7.01 pH

Repeat the operation for pH 4.01 solution (HI 7004). The difference from the previous reading must be near 3 pH.

Storage

To minimize clogging and assure a quick response time, the glass bulb and the junction should be kept moist and not allowed to dry out. This can be achieved by installing the input lines in such way that the probe holder is kept filled with sample.

When not in use, for longer time, dismount the probe and keep in the protective cap with a few drops of HI 70300 Storage Solution or, in its absence, HI 7082 (KCl 3.5 M Solution).

Follow the Preparation Procedure above before remount the probes.

Note: Never store the probe in distilled or deionized water.

Periodic maintenance

Inspect the probe and the cable. The cable used for the connection must be intact and there must be no points of broken insulation on the cable or cracks on the probe stem or bulb.

Cleaning procedure

IMPORTANT: After performing any of the cleaning procedures rinse the

Cleaning Solution.

probe thoroughly with distilled water and soak the electrode in HI 70300 Storage Solution for at least 1 hour before

reinstalling it.

Evaluate your probe performance based on the following.

• Noise (Readings fluctuate up and down) could be due to clogged or dirty junction: refer to the Cleaning Procedure above.

• Dry Membrane/Junction: soak in Storage Solution HI 70300 for at least 1 hour. Check to make sure the installation is such as to create a well for the probe bulb to constantly remain moist.

• Drifting: soak the probe tip in warm Hanna Solution HI 7082 for one hour and rinse tip with distilled water.

• Low Slope: refer to the cleaning procedure above.

• No Slope:

- Check the probe for cracks in glass stem or bulb (replace the probe if cracks are found).

- Make sure cable and connections are not damaged.

• Slow Response/Excessive Drift: soak the tip in Hanna Solution HI 7061 for 30 minutes, rinse thoroughly in distilled water and then follow the Cleaning Procedure above.

• For ORP probe: polish the metal tip with a lightly abrasive paper (paying attention not to scratch the surface) and wash thoroughly with water.

CHANGING PERISTALTIC PUMP TUBING

It is recommended that the peristaltic pump tubes be changed on a regular basis depending on sampling period and operating time.

For a 5 minutes sample interval and continuous operation, changing of the tubes every month is recommended. For best results however, change the tubings every time the reagents are replaced.

Note: Rubber gloves and eye protection must be worn while han-

dling reagent tubing to prevent contact with reagent chemicals. Read MSDS documents before proceeding.

Grasp the plastic collar of one pump tube and pull the fitting away from the pump toward the front of the case until it clears the retaining indentation.

Then move the fitting sideways away from the pump until the tube clears the slot.

Release the tube and fitting. The fitting on the other end of the pump tube may now be easily removed from the pump body.

Remove the reagent tubing from one end of the pump tube fitting and pull the pump tube from behind the pump rollers.

Replace the pump tube with a new one and reassemble in reverse order. Repeat for the other pump tube.

TUBING REPLACEMENT

The remaining tubing in the analyzers should be replaced every two months.

HI 70479

When installing new tubing it is helpful to dip them in hot water before making the connections.

It is also recommended that one tube at a time is removed and replaced.

Note: DPD reagent tubing may darken before the scheduled replace-

ment time, but this will not affect the instruments performance.

CLEANING MEASUREMENT CELL

In order to maintain the maximum reliability of measurements, it is recommended to periodically clean the measurement cell. In fact, the measurement cell could collect sediment or develop a film growth on the inside walls. When the automatic dirt compensation system detect the deposits presence, the analyzer will show “Dirty cell” message.

The measurement could continue but cleaning is recommended to avoid deposits that are harder to clean.

Thorough cleaning with a dilute acid solution and a cotton swab is recommended monthly. Depending on sample conditions at individual locations and absence of input filters, it may be necessary to clean the cell on a weekly basis. This can be determined by observing the cell condition when reagents are changed.

It is also highly recommended to clean the cell every time you turn the meter off. In such a way, scaling and molds growth are prevented. Otherwise, subsequent cleaning might become more difficult.

For cleaning procedure, remove the plastic cap placed on the top of the measuring cell.

Add a few drops of 19.2N Sulfuric Acid solution or alcohol to the cell.

HI 70474 or HI 70475

HI 70473

Allow sulfuric acid to stand in the measuring cell for 15 minutes to dissolve any foreign materials adhering to the cell walls. Wipe the cell interior with a cotton-tipped swab. After wiping, open the drain port to empty the measuring cell from the cleaning solution.

CHANGING MEASURMENT CELL

To change the measuring cell (#7 page 10) with a new one (HI 70487) in the PCA310 - 330 analyzers, follow the steps:

• Stop the analyser by turning off the main switch.

• Remove the reagent and buffer bottles to free space.

• Disconnect the reagent and buffer tubes from the cell

body.

• Disconnect the sample inlet tube from the cell body. This

tube is between electrovalve (#21 pag 10) and cell.

• Disconnect the drain tube (#8 on page 10) from the cell.

• Unplug the cell connector.

• Unscrew the cell from its support by using hexagonal

wrench.

• Put the new cell in its place and screw it in position. Take care to position the electrical cable first.

• Reconnect the electrical wires and the pneumatic circuit as it was at the dismounted cell.

• Power on the PCA310 - 330 analyzer.

• Go to menu mode “Chlorine Menu” - “Cal measuring

Cell” and start the “Calibration Blank” function.

• Confirm by pressing “CFM” when asked “Start the blank calibration?”.

• Wait for the end of the procedure.

• If the message Press CFM appears, the procedure was

successful and Pressing “CFM” will save the coeficients for the new cell.

• If the message “failed” appears, the cell is not working properly. Check the electrical cable connection and if the error persist call Hanna Service.

• Prime the reagent pump - see page 36 for details.

• Wait 3 cycles for the measurement to stabilize.

• Calibrate the measuring cell as described at page 40.

Note: Before start measuring assure that a stirring bar (HI 70487)

is present in the cell.
