English 31

Table 13 Digital output – default states

Alarm type Description

TOC alarm High state—The TOC level is below the selected upper limit.

Low state—The TOC level is above the selected upper limit.

When enabled, any online TOC reading that is more than the alarm upper limit triggers a TOC alarm.

Conductivity alarm High state—The conductivity level is below the conductivity limit.

Low state—The conductivity level is above the conductivity limit.

The actual (uncompensated) conductivity limits are in accordance with the specifications set forth in the method “<645> Water Conductivity” of the USP 25–NF 20 (January

2002). Refer to Conductivity alarm limit on page 32.

For proper operation of the conductivity alarm, uncompensated conductivity must be selected under the Display tab in the System settings.

Error state High state—No error conditions are present.

Low state—An error condition is present.

Valve state (TOC analysis start)

High state—The inlet sample valve is open.

Low state—The inlet sample valve is closed.

Conductivity alarm limit

The actual sample water temperature is rounded down to the nearest 5 degrees to set the conductivity limit. This makes sure that any potential excursions are identified early. For example, if the measured water temperature is 24.5 °C, the 20 °C limit is applied and an alarm is triggered if the conductivity is more than 1.1

μS/cm U.

To make sure of an agreement between all data outputs, the TOC, conductivity and temperature values are all rounded to have the same accuracy as the analyzer for alarm limit checking, display, printouts and any digital outputs.

Troubleshooting

The analyzer incorporates extended diagnostic and reporting to inform the user about the nature of a problem.

Alarm codes, with user-initiated diagnostic tests, serve to isolate the source of the problem. The analyzer constantly monitors its operation and measurement values for alarm conditions.

Alarm conditions include error alarms, critical error alarms, warning alarms and measurement alarms.

Alarms

Alarm indication

The analyzer has two basic operational modes: online and bottle. The online TOC and conductivity are the two primary online modes. In online TOC and conductivity modes, the measurement screen shows an animation that identifies the general state of water flow through the analyzer.

In online TOC, conductivity, or manual TOC modes, the animation area is also an alarm condition indicator. When an alarm occurs in an online mode:

• The animation area flashes red.

• The value of the variable that has caused the alarm becomes red.

• The alarm sound** is heard if enabled.

• The alarm condition is recorded to the data log and audit trail.

• The alarm icon is enabled.

• Error, critical error or warning: The digital output that represents the error state identifies an error condition. Refer to Configure the digital output alarms on page 31.

• Error or critical error: The three analog outputs identify an error condition (2 mA or 22 mA). Refer to Configure the analog outputs on page 33.

Each type of alarm (stop, warning, alarm) has a different sound. If multiple alarms occur, only the highest-level alarm is heard.

42 English

After an alarm is acknowledged:

•

The animation area shows steady red.

• The alarm sound is not heard.

• Once a full cycle has occurred without any errors, the error is removed and the normal animation shows. The digital output will no longer show an error state and the analog outputs represent the new valid result.

• If on the next cycle the same or a new error occurs, the animation area again flashes red and must be acknowledged.

• As long as alarms are present in the alarm log, the alarm log is available.

Accept or remove an alarm

When a warning or an error that is not critical occurs, the animation area of the measurement screen flashes red.

1. Push << to show the sliding menu.

2. Select ALARMS. The Alarm Acknowledge screen opens.

• Push ACCEPT ALARMS (bell with green checkmark) to acknowledge the alarm.

• Push DELETE ALARMS (bell with a red X) to delete all alarms in the list.

3. Push ENTER to return to the measurement screen. If the error condition still exists but has been

accepted, the animation area shows steady red.

Error codes

Table 16 shows the error codes that occur any time one of the non-critical subsystems fail or a failure

occurs from which the analyzer tries to recover.

When an error occurs, the animation area flashes red to identify when an error condition is present. In addition, the digital output that represents the error condition and the three analog outputs (2 or 22 mA) change their state to identify when an error condition is present. Refer to Alarm indication on page 42.

When the error condition is removed, the analyzer attempts to recover and continue to operate. Once a valid TOC measurement is completed, the analog outputs once again represent the measured values.

Appendix

Theory of operation

The analyzer enables TOC analysis for pure and ultra-pure water processing. The analyzer oxidizes a water sample to find the TOC in the sample. The analyzer traps a water sample in the analysis cell, exposes the sample to ultraviolet (UV) light to oxidize a sample of water (photolysis) and monitors changes in temperature and conductivity until the sample has completely oxidized. Once full oxidation has occurred, the analyzer reports TOC.

Conductivity (in µS/cm) or resistivity (in MΩ-cm)—unadjusted for temperature or corrected to 25°— and sample temperature are measured and shown along with the oxidation curve type and TOC trend. The analyzer includes an integral inline filter, flow control valve and heat exchanger to make sure that the proper water flow rate and temperature are accurate for TOC analysis. An internal pump is available for sampling water from a supply with no pressure and to deliver standards to the analysis cell from the Onboard Automated Standards Introduction System (OASIS™).

OASIS™

(onboard automated standards introduction system) simplifies analyzer performance tests with standards bottles tagged with Radio Frequency Identification (RFID) technology, which is a registered radio frequency device. The RFID system transmits data wirelessly with radio waves and operates over a very short distance to prevent interference with other wireless communications.

The RFID system communicates with tags and reader/writers. In the analyzer, the tag is attached to the bottom of the standards bottles used in calibrations (conductivity and TOC), validations, system suitability tests and excursion mode. The tag has a microchip attached to a radio antenna connected to a substrate. The microchip keeps data about the standard contained in the bottle.

The OASIS system has four RFID reader/writers permanently attached inside the analyzer that align with the bottle RFID tags when the bottles are fully loaded in the analyzer. The reader/writer retrieves data from the tags. The tag keeps data about the identity of the standard, the concentration of the standards, expiration date and other pertinent data. The reader/writer receives data from the tag and sends the information digitally to the processor.

The RFID system can read and write to the tags attached to the standards bottle. This enables the analyzer to write data to the bottles that shows the bottle has been used and also supplies data for the exclusive excursion sampling feature.

The system operates without any user intervention and operates automatically when bottle tests are done. The system powers on and off to read and write data only when necessary. The RFID labels on the standards bottles contain the data necessary for each standard, the labels must not be removed from the bottle. Without the label, the reader/writer has no data to read and will not operate as intended, although bottles without labels can be used if the user manually enters data.

A touch-screen interface gives access to all analyzer functions. The user interface has a home screen from which all user operations initiate. The home screen shows the current status of the analyzer and analysis results based on the current run mode selection. The software can show data in a number of user-selected formats, e.g., TOC, compensated and uncompensated conductivity, resistivity and temperature in engineering units with data logging and graphing of the data.

A user may connect a USB flash drive to the analyzer and download the contents of the data buffer, audit trail, alarm log and bottle analysis reports. Query the analyzer through an RS232 communications port to remotely interact with the analyzer and also download data records. Or communicate with the analyzer with Modbus® protocol via the Ethernet port. Print automatically or on demand with an RS232 port to a serial printer.

English 51

The analyzer permits compliance to 21 CFR Part 11 with password protection and an audit trail of all user actions.

Analyzer startup sequence

The analyzer goes through the sequence that follows when the power switch is set to on.

Splash window: The splash window shows at startup while the system launches the application.

2. Verify lamp monitor: After the system has initialized, it verifies that the lamp monitor works. The

main lamp is set to on and the analyzer makes sure that a voltage is returned.

3. Sample bottle check: The system identifies if the bottles loaded in the bottle bay match the last known configuration. If the bottles contain RFID tags, the analyzer reads the tags and compares them against the information saved in the settings. If the RFID tag does not match what is saved in the settings, the settings are updated with the new information and a warning is triggered. If the settings list a non-RFID tagged bottle in one of the bottle positions and an RFID tag cannot be detected in that position, the analyzer assumes the bottle is still present.

4. Start sampling: If the analyzer is configured for online TOC, it starts to take a sample after power is supplied.

5. Print header: After the system has started up, it prints a daily header if a printer is attached.

Run modes

The analysis cycle

An analysis cycle includes a flush of the analysis cell, oxidation and idle time. Idle time occurs only after an online TOC analysis is completed and only if the elapsed time (combined flush and oxidation time) is not more than the cycle time. The oxidation time changes based on the amount of total organic carbon in the sample. The flush time is configurable. The idle time changes based on the cycle time.

During idle time, the analyzer can operate in one of three ways: flow without conductivity, flow with conductivity or no flow. Refer to Configure the general settings on page 27.

To select the run mode, refer to Select the run mode on page 23. Descriptions of the run modes follow.

Online TOC mode

In online TOC mode, the cell valve opens to flush the cell. When flushing is completed, the sample valve closes, the analysis starts, and initial conductivity and temperature readings are sent to the TOC algorithm. Conductivity is monitored until the oxidation is completed.

When oxidation is completed, the analyzer reports the results to the home screen, the data log and the printer, based on the printer settings and if the printer is connected. If the elapsed time is more than or equal to the cycle time in settings, the next online TOC analysis is started. If not, the analyzer goes to the idle mode.

Conductivity mode

In conductivity mode, the home screen shows the conductivity and temperature readings.

In conductivity mode, the analyzer first makes sure that the UV lamp is off and the cell valve is open to flush the cell. The analyzer reports the current readings for conductivity and temperature every time a new value is available. The reported value is an average of the data over the last two seconds. The average reading is also sent to the printer, based on the printout settings and to the data log. One data point is sent to the log every 60 seconds.

CIP Validation mode

In CIP Validation mode, the home screen highlights the TOC reading, with conductivity, temperature, sample time and curve type shown in smaller text. Additionally, the initiate CIP sampling Run button is shown on the right side of the display.

When the CIP Validation button is pushed, the analyzer measures conductivity until the readings goes below a specified threshold or until a specified time interval has expired. Then, the instrument starts one TOC analysis. When the TOC analysis is completed, the analyzer goes to the Idle state.

52 English

Standby mode

In standby mode, the analyzer makes sure that the lamp is off and the valves are open. To exit standby mode, select a different run mode.

Offline mode

In offline mode, the analyzer makes sure that the lamp is off, the valves are closed and flow through the analyzer has stopped. To exit offline mode, select a different run mode.

Manual TOC sample

A TOC analysis can be done manually. Push the TOC manual sample

icon, then select the source stream for analysis if a dual-stream analyzer. The analyzer immediately stops its current operation and then does one TOC analysis. When the analysis is complete, the analyzer goes back to the mode selected on the run mode screen.

Self clean mode

Select the source stream for the self-clean operation if a dual-stream analyzer. If Timed is not selected, the self cleaning continues until it is stopped by the user.

In manual self clean mode, first the elapsed time is set to 0, the cell valve is opened to flush the cell and the lamp is set to on. If Timed is selected, the time that remains shows. If Timed is not selected, the elapsed time shows.

To stop the cleaning, push the red X or select a different run mode.

Bottle mode

Calibration and validation

Bottle mode is used to do calibration, validation and system suitability test procedures. Proper calibration of the analyzer is critical to optimum instrument performance. Such functions can be done automatically with the Onboard Automated Standards Introduction System (OASIS™) with the touchscreen interface. This method minimizes user intervention with the use of a prepackaged standards kit with RFID technology. Calibration, validation and system suitability test procedures can be done immediately or scheduled to be done later.

• Calibration assures the accuracy of instrument readings at regular intervals. This instrument is

calibrated at the factory before shipment. It is not necessary to do a TOC calibration before the analyzer is put into service.

• Validation ensures the accuracy of the calibration. A standard solution of known value is analyzed

to challenge the calibration.

• Calibration and validation involve the analyses of one or more standard solutions and blanks

(protocols) to identify the analyzer response.

• In bottle mode, the analog output stays at the last online TOC, conductivity and temperature

values. The TOC and conductivity alarms are deactivated.

Five functions are available under bottle mode: run standards, grab sample, excursion mode, bottle flush and unload bottles.

Onboard Automated Standards Introduction System (OASIS)

The PAT700 Onboard Automated Standards Introduction System (OASIS) is used to do standards tests, grab sampling and excursion sampling. Through the bottle mode, various bottle test functions can be selected. The OASIS system is automated through the use of RFID technology. Refer to

RFID technology on page 53. When standards bottles with RFID tags are installed in the system,

the analyzer uses RFID technology to read and transmit data about the standards to the analyzer. This system removes the need for manual data entry.

Bottles without RFID tags may also be used. The standards data is entered manually when prompted by the analyzer.

RFID technology

The PAT700 analyzer Onboard Automated Standards Introduction System (OASIS™) uses Radio Frequency Identification (RFID) technology, a registered radio frequency device. The RFID system in

English 53

the PAT700 analyzer operates over a very short distance to prevent any interference with other wireless communications.

The term RFID describes a system that transmits data wirelessly using radio waves. An RFID system is includes a “tag” and a “reader/writer”. The tag is attached to the standards bottles used in calibrations (conductivity and TOC), validations, system suitability tests and excursion mode. The RFID tag includes a microchip attached to a radio antenna mounted on a substrate. The RFID tag is attached to the bottom of the standards bottle. The microchip contains data about the standard contained in the bottle. The PAT700 OASIS system contains four RFID reader/writers that are permanently mounted inside the analyzer. The RFID reader/writers align with the bottle RFID tags when the bottles are fully loaded in the analyzer.

The reader/writer retrieves the data stored on the RFID tags located on the bottom of the standards bottles. The RFID reader/writers have antennas that emit radio waves and receive signals back from the tags on the standards bottles. The information provided from the tag includes the identity of the standard, the concentration of the standard solution, date of expiration and other pertinent data.

The reader/writer takes the data received from the tag and passes the information in digital form to the PAT700 processor. The RFID system in the PAT700 can read and write to the RFID tags attached to the standards bottle. The writing feature lets the PAT700 write data to the bottles identifying that the bottle has been used and provides for writing of data for the exclusive excursion sampling feature.

The RFID system in the PAT700 does not require any user intervention to operate. The system operates automatically when bottle tests are done. The system automatically switches on and off to read and write data only when necessary. When enabled, the radio frequency modulation emitted from the antennas is fixed at 13.56 Mhz. There are no user-serviceable parts associated with the RFID system. The RFID reader/writer board assembly should only be serviced by a Hach certified service representative.

Since the RFID labels on the standards bottles contain the data necessary for each standard, the labels must not be removed from the bottle. Without the label, the RFID reader/writer has no data to read and will not operate as intended. However, bottles without labels can be run if the user manually enters data.

Data log

The data log holds up to 5,000 records. The data log contains analysis results, alarms, bottle test results and audit trail entries. Since the audit trail is kept in the data log, each audit trail entry uses one of the 5,000 data log entries.

The data log operates in a first in first out approach. Once the data log contains 5,000 entries the oldest entry is replaced with the newest entry.

The contents of the data log shows in the Data Review screen. Refer to Manage measurement data on page

26. The Data Review screen is populated only when data logging is selected in the security settings. The Data Review screen shows a list of all the data in the data log as will show on a printout.

The data shown on the Data Review screen is filtered based on the settings in the filter dialog box. Refer to Set the data filter on page 26. Data is shown in chronological order from earliest to most recent. The list scrolls to display the earliest data.
