Introduction

1.1 How to Use the ManualsThis instrument requires two manuals for complete operating instructions; the APA 6000 Installation and Maintenance Manual and a parameter-specific operation manual. This APA 6000 Installation and Maintenance Manual (Cat. No. 62005-18) provides instructions for instrument installation, menu setup, operation, maintenance, and troubleshooting. The parameter-specific manual contains information related to parameter specific instrument components and software functions. Descriptions of reagents and standards and their consumption rates, method of analysis, operational sequence, and bench comparison testing are all addressed in the parameter-specific manual.

1.2 How the Analyzer WorksThe APA 6000 Process Analyzer is a microprocessor-controlled process analyzer designed to continuously monitor a specific substance in a sample stream (see Figure 1). The analyzer consists of five basic components: Figure 1 Module Components AquaTrend Interface Autoburette Module Detector Module and Holding Coil Valve Module Mixer Module

6200518 Introduction.fm

Page 7 Introduction

Section 11.2.1 ComponentsThe AquaTrend Interface The APA 6000 Process Analyzer has an AquaTrend Interface built into the instrument door. It provides a numerical or graphical display and a keypad for user input. The AquaTrend Interface displays, graphs, and logs sensor readings, and is used for operator control and sensor setup. Autoburette Module The analyzer uses a positive-displacement autoburette to measure fluids through the various analytical components in the instrument. The autoburette module consists of a clear acrylic block which houses a ceramic piston, a double seal for the piston, a linear actuator, a two-way solenoid valve, and control circuitry. Detector Module Samples are measured in a temperature controlled flow cell detector. All detector modules contain a holding coil. The holding coil acts as a storage area for fluids as they are drawn into the instrument before being directed to the appropriate module for mixing or sensor readings. The detector module for some instruments also contains a reaction coil. The reaction coil optimizes the dispersion utilized in some analysis methods. Valve Module The valve module directs fluids to various components in the instrument. Mixer Module The mixer module mixes reagents with the sample or standards. The mixing action also removes excess air from the sample.

1.2.2 Flow Through the InstrumentThe following is a simplified version of how fluids are cycled through the analyzer: 1. In a normal measuring cycle, the instrument uses the autoburette module to draw sample in through the sample conditioning block into the holding coil. 2. The pump then draws reagent(s) into the holding coil. 3. Next, the pump moves the reagent(s) and sample from the holding coil into the mixing module with the sample. 4. When the sample and reagent are adequately mixed, the instrument draws the mixture into the holding coil. 5. The next pump actuation moves the mixture from the holding coil into the reaction coil (not used in all chemistries). As the mixture flows past the reaction coil and through the detector, a measurement is taken and the fluid continues to flow into the drain. The cycle then starts over again at Step 1.

Installation

2.1 Selecting a Location for the APA 6000 AnalyzerLocate the analyzer as close to the sampling point as possible. Shorter distances between the process stream and the analyzer mean faster analyzer response to changes in analyte concentration. Long sample lines are also more vulnerable to sediment accumulation. Do not place the sampling point near a point of chemical addition. The process stream at that location may be inadequately mixed, yielding erroneous readings. The instrument enclosure is designed for general-duty, indoor installation. Do not mount the analyzer in direct sunlight. Ambient temperatures may range from 550 C (41122 F), but best performance will result if ambient temperature is between 5 and 35 C (41 and 95 F). Use Figure 2 to determine the space needed to install the instrument. To control the analyzer from a location other than the instrument location, connect a remote AquaTrend Interface. It can be mounted on a bench, pole, or panel as far away as 400 m (1320 feet). Figure 2 Overall Dimensions of the APA 6000 Analyzer

2.2 MountingAn installation kit (Cat. No. 51040-00) is supplied with the instrument. The kit includes: Grab sample kit (Cat. No. 62037-00) Four 0.5 micron filters (Cat. No. 62011-00) 20 ft. of -in. poly tubing (Cat. No. 47438-00)Page 13 Installation

Section 22.2.1 Bench MountImportant Note: The analyzer must be bolted to the bench.

Secure the rear of the instrument to the bench or table with two -20 UNC screws through the holes in the metal frame on the back of the instrument (see Figure 3). This will prevent the instrument from tipping while the module panel is open.

2.2.2 Wall MountThe back plate of the instrument has four key-shaped holes for wall mounting. The analyzer can be mounted directly to a wall or to rails capable of holding 157.5 kg (350 lb.). Leave at least 4656 cm (1822 in.) of space above the top of the bolt pattern (see Figure 3) to allow access to the reagent enclosures. 1. Make sure no power is supplied to the analyzer. 2. Install the top two 3/8-16 UNC hex bolts into the wall or fixture according to the dimensions in Figure 3, leaving a -inch gap under each bolt head. 3. Slide the bracket keyholes onto the bolts and lower the frame so the bolts settle in the narrow part of the keyholes. 4. Install two bolts through the lower holes in the frame, into the wall or fixture. 5. Tighten all four bolts securely. Figure 3 Mounting Dimensions

Section 22.3 Electrical ConnectionsDANGER All electrical connections should be made by a qualified technician to assure compliance to all applicable electrical codes. DANGER Tous les branchements lectriques doivent tre effectus par un technicien qualifi pour assurer la conformit toutes les normes lectriques applicables. PERIGO Todas las conexiones elctricas deben ser ubstaladas por personal tcbico cualificado a fin de asegurar su conformidad con las normas elctricas vigentes. GEFAHR Alle elektischen Anschlsse mssen van qualifizierten Techniekem durchgefhrt werden, damit die bereinstimmung mit allen elektrischen Anschlussdaten gewrhrleistet ist. PERICOLO Tutte le connessioni elettriche devono essere fatte da un tecnico qualificato.

To access electrical connections in the APA 6000 instrument, remove the two hold-down fasteners in the upper corners of the module panel. Slowly pull the panel forward until it is fully supported by the steel restraining cable (see Figure 4 and Figure 5). Four access holes for electrical connections are provided along the back of the instrument enclosure (see Figure 6). Remove the cover seals by loosening the wing nuts from inside the instrument. This product is designed to meet NEMA 4X (INDOOR) and IEC 529 IP 66 enclosure requirement when the front door is securely latched. Achieving these protection levels, however, depends on the use of proper hardware in the installation of this product. Standard off-the-shelf NEMA-approved conduit hardware is required for proper installation of all electrical connections. For process or industrial applications, the national electrical codes of most countries require that ac service feeds be hard-wired and contained in conduit systems. The APA 6000 Analyzer has been designed to conform to this requirement. Hach recommends conduit for two reasons: 1. It is generally required by most local electrical codes, and 2. use of metal conduit can improve immunity to lightning surges and ac power transients. In hard-wired electrical applications, the power and safety ground service drops for the analyzer should be no longer than 6 meters (20 feet) unless metal conduit is used to shield the ac power wiring. In applications where power cords are allowed by local electrical codes and power surges and transients are not a great concern, an 18-gauge, 3-conductor power cord (including a safety ground wire) can be used, but its length must not exceed 3 meters (10 feet). The power cord or power cable is not supplied with the APA 6000 Analyzer and must be selected to meet applicable electrical codes for the installation site.


Page 15 Electrical Connections

Section 2Hach recommends that care be taken with hook-up configurations other than shown in these illustrations. First, be sure your configuration satisfies local electrical codes and second, ensure that your configuration does not cause susceptibility to lightning, power surges, or transients upsets.

2.3.1

Power Connections at the AnalyzerIf power cords are allowed by local electrical code, a 125 V UL/CSA-approved power cord with an approved NEMA-style strain relief and a standard 115 V North American-style plug (Hach Cat. No. 46306-00) or a 230 V VDE-approved power cord with an approved NEMA-style strain relief and a Continental European-style plug (Hach Cat. No. 46308-00) can be ordered. The APA 6000 Analyzer operates on any ac line voltage from 95240 V ac, 50 or 60 Hz. A 12- to 18-gauge power lead supply wire (power cord), with insulation rated at 300 V (600 V peak), is required. The analyzer is designed for hard-wire connection to ensure conformation to local electrical codes.

Note: Be sure the analyzer power switch is turned off. Dry operation may damage the analyzer.

Route the power leads through the access hole on the back of the enclosure. Line voltage connections are wired directly to the terminal strip J10 (see Figure 6 and Figure 7). Make the ground connection to the adjacent ground stud using an appropriate closed loop connector (see Table 1). Table 1 Wiring Color Codes

Section 22.3.2 Alarm Relay ConnectionsDANGER La zone de raccordement des relais est conue pour des connexions soit tout en basse tension (30 V). Un risque dlectrocution existe si des connexions basse et haute tension sont faites dans la zone de raccordement des relais. PELIGRO El rea de conexin de los rels esta diseada para conexiones que sean todas de baja tensin (inferior a 30V o bien todas de alta tensin (superior a 30V). Existe riesgo de descargas si se combinan conexiones de alto y bajo voltaje en el rea de conexin de los rels. GEFAHR Die Ralaisanschlsse sind entweder fr Niederspannung (< 30V) oder fr Hochspannung (>30 V) vorgesehen. Wenn sowohl Nieder-als auch Hochspannung an die Relais angeschlossen wird, kann es zu einem Stromschlag kommen. PERICOLO La zona riservata ai contatti di allarme disegnata per bassi voltaggi ( 30V). Assolutamente non confondersi nell'utilizzo dei bassi e degli alti voltaggi. Note: Limit current to the relay contacts to 5 amps. This can be accomplished with an external switch and a 5-amp fuse or with a switched 5-amp circuit breaker. You must be able to remove power from the relays locally in case of an emergency or for servicing of the product.

DANGER The relay connection area is designed for either all low voltage (30 V) connections. A shock hazard exists if low and high voltage connections occur simultaneously in the relay connection area.

The analyzer contains two alarm relays designed for use with either high voltage (greater than 30 V-RMS and 42.2 V-PEAK or 60 V dc) or low voltage (less than 30 V-RMS and 42.2 V-PEAK, or less than 60 V dc), but not a combination of both high and low voltage. Wire alarm relays to the connectors labeled Alarm A or Alarm B on the back electrical panel (see Figure 8). For terminal strip and strain relief locations see Figure 6. SPDT relay contacts are unpowered and rated to carry up to 5 amperes at 240 V ac with a resistive load. If high-current or inductive-load devices are to be controlled by analyzer alarms, use a heavy-duty slave relay actuated by the alarm relay. Both normally open and normally closed contacts are available. The connector will accept 22- to 12-gauge wire, insulated as appropriate for the voltage. Size the wires according to the load and local electrical code regulations. If more relays are desired, supplement your system with the AquaTrend Signal Output Module (SOM) (Cat. No. 51250-00). Each SOM provides two additional relays.

DANGER Facility power systems may have ground potentials if poor grounding techniques have been used. To reduce the chance of shock hazards, care must be taken when connecting equipment grounded at different locations (potentials). Carefully follow the instructions given in this section.

The analyzer contains two isolated 420 mA analog outputs which can drive a recorder or control a process (see Figure 9). Recommended output impedance is 3.6 to 500 ohms. Route 22-to 12-gauge recorder wires through the access hole below the terminal strip and connect them to the terminalPage 21 Electrical Connections


Section 2strip J8, labelled Recorder (see Figure 6). Use shielded, twisted-pair cable to connect the analyzer to the recorder. Tie the shield to earth ground only at the analyzer end to avoid ground loops. To ensure the analyzer meets NEMA 4X and IP 66 enclosure ratings, use only NEMA-style enclosure strain relief fittings. If more analog outputs are desired, you can supplement your system with the AquaTrend Signal Output Module (SOM). Each SOM provides two additional analog outputs.

Hach Company assumes individuals performing these tasks are qualified and aware of proper safety procedures.

CAUTION This instrument is not intended for use with flammable samples or those containing hydrocarbons.

PRUDENCE Cet instrument nest pas conu pour une utilisation avec des chantillons inflammables ou des chantillons contenant des hydrocarbures. CUIDADO Este instrumento no est destinado para uso con muestras inflamables o que contengan hidrocarburos. VORSICHT Dieses Gert darf nicht fr Tests mit brennbaren Proben oder Proben, die Kohlenwasserstoffe enthalten, benutzt werden. ATTENZIONE Questo strumento non utilizzabile con campioni infiammabili o contenenti idrocarburi.

Section 2DANGER This instrument should be installed by qualified technical personnel to ensure adherence to all applicable electrical and plumbing codes. DANGER Cet appareil doit tre install par du personnel technique qualifi, afin dassurer le respect de toutes les normes applicables dlectricit et de plomberie. PELIGRO Este instrumento debe ser instalado por personal tcnico capacitado para assegurar el cumplimiento con todos los cdigos elctricos y de plomera aplicables. GEFAHR Um zu gewhrleisten, da alle elektrischen und sanitrinstallationstechnischen VDE-Vorschriften und gegebenefalls die Zusatzvorschriften der zustndigen Elektrizitts- und Wasserwerke erfllt werden, darf dieses Gert nur von geschultem Fachpersonal installiert werden. PERICOLO La strumentazione deve essere installata da personale qualificato, sia per le connessioni elettriche sia per quelle idrauliche.

2.4.1 Sample Line InstallationSelecting a good, representative sampling point is important for optimum performance from the analyzer. The sample analyzed by the analyzer must be representative of the condition of the entire system. If a sample is drawn from a location too close to points of chemical additions to the process stream, inadequate mixing or an incomplete reaction can result in erratic readings from the analyzer.Note: Plumbing connections should be made only by qualified personnel to assure conformance to all applicable plumbing codes.

Run sample lines with small diameter tubing to the analyzer to minimize lag time (the time required for sample to flow from sample point to the analyzer). Route the tubing as directly as possible between the sampling point and the analyzer. Long sample lines and low flow rates result in significant lag time between actual process line conditions and the sampling point of the instrument. Install sample line taps into larger process pipes to minimize the chances of ingesting sediment from the pipe line bottom or air bubbles from the top. A tap projecting into the center of the pipe is ideal (see Figure 10).

Section 2New tubing, valves and other sample conditioning equipment may be contaminated with substances (oils, dust, etc.) which may contribute to low or high readings on initial startup. Flush the sample line with sample for 12 hours before calibration. For faster cleaning, plumb the sample line to a container of 14 liters of a dilute caustic solution such as 1 N (5%) sodium hydroxide solution and cycle it through to clean sample system components. When the solution is depleted, connect the sample line to the sample source and run the analyzer for an hour to purge the sodium hydroxide solution.

2.4.1.1 Sample ConditioningThe analyzer is equipped with a sample conditioning block that includes a 0.5 m filter. The unit is located on the left side of the instrument. See Figure 11. Use -in OD poly tubing from the sample source to the sample conditioning block. The tubing connects to the block through the lower push-in fitting. From the upper push-in fitting of the sample conditioning block, excess sample flows to drain. A vent assembly is required to avoid excess vacuum at the sample conditioning block. The vent should be located above the sample conditioning block. For wastewater applications or other samples containing high solids, an APA 6000 Micro Filter System is recommended (Cat. No. 51339-00, 115 V model or Cat No. 51339-01, 230 V model). A 40-mesh y-strainer (Cat. No. 46618-00) can be used to remove large solids alone or with the Micro Filter System. When testing highly aerated samples, the manufacturer recommends installing a Process Sample Heater such as Cat. No. 48685-00, prior to the sample conditioning unit. Warming the samples removes some of the excess air and stabilizes the analyzer readings.Important Note: Sample conditioning requires regular maintenance for proper operation. Important Note: If the sample conditioning system supplied with the instrument is removed, it must be replaced with an alternative filtration system of 0.5 m or smaller. Failure to provide the required filtration will void the instrument warranty.

2.4.2 Drain Line ConnectionNote: It is imperative to mount the drain point below the instrument drain block. Failure to do so may result in improper functioning of the instrument or back flow of waste into the instrument cabinet.

The analyzer is connected to a drain system through a -inch hose barb fitting on a drain block on the right side of the analyzer case (see Figure 12). After analysis, the waste exits the instrument through the manifold at the bottom of the instrument and into the drain block. This block connects to a -inch ID hose and provides a vented vacuum break at this point. A vent is located on the top of the drain block. Also see section 2.4.2.1. Route instrument waste through a -in. ID hose to a PVC pipe assembly, which must be located one foot below the level of the instrument drain block. The catastrophic drain is located in the middle of the tubing manifold and is sized to accommodate a 1-in. ID hose. This drain is used if an upset inside the instrument results in a significant leak. The supplied hose from this drain port must be connected and run to a drain which is one foot below the bottom of the instrument. The reagent enclosures each have an overflow fitting in the bottom of the case. Plumb these to the drain by punching out the knock-out in the fitting, attaching a 3/8-inch ID hose to each fitting and running it to a drain which is one foot lower in elevation than the bottom of the instrument.

2.4.2.1 Waste DisposalThe effluent from the APA analyzer is non-hazardous per federal RCRA regulations and may be safely discharged to a sanitary sewer based solely on federal rules. Other state and local regulations or permitting requirements may apply and it is the responsibility of the end-user to know and apply state or local requirements to their specific applications. Hach Company does not advocate the pouring, dumping, or discharging of any chemicals, hazardous or nonhazardous, to the ground or to septic systems.

2.5 Air PurgeAir purge may be necessary if the analyzer is located in an environment with high humidity and/or caustic vapors. The goal is to maintain a slight positive pressure in the instrument with dry instrument air. The air purge connection is located in the middle of the back of the instrument. To connect an air supply, remove the plug in the quick connect fitting. Connect in. poly tubing by pushing the tubing into the fitting. You should feel two distinct stops as you push. If the tubing is not seated, it will pop out when air pressure is applied. Use only dry instrument air at 15 scfh (7 L/min.)

Section 33.1 Introduction

Startup

It is assumed that the analyzer has already been plumbed to the sample source and a drain, as well as wired to a power source and any other electrical wiring associated with 420 mA connections, relay connections, and network connections by the installation technician as outlined in Section 2. This section presents the steps, in sequence, an operator should take to begin operation. This section will: describe how to prepare the sample conditioning describe the steps to install the reagents and standards list the steps required to prime the sample lines and reagents.

3.2 Preparing Sample Conditioning and Starting Sample FlowThe analyzer is supplied with a 0.5 m ceramic filter (already installed in the sample conditioning block) and four replacement filters. 1. Set the sample flow rate through the sample conditioning block in the following range: 10002000 mL/min. 2. Check the flow at the air break of the drain (where the tubing from the sample inlet block meets the drain tee). If desired, measure the flow rate by directing the sample into a large measuring container (flask or cylinder) over a set amount of time. Keep the end of the tube at the same height as the push-in fitting. 3. Ensure that the filter is tightly threaded into the sample conditioning block to prevent unfiltered sample from entering the analyzer.

3.3

Installing Reagents and StandardsThe solution bottles are labeled (i.e., Reagent 1, Standard 1, Cleaning Solution). The tubing into each of these bottles is also labeled with the solution name to prevent reagent line mix-ups. Some analyzer solutions require special accessories and handling. Please see the parameter specific manual for more information. To change solutions, follow these instructions: 1. Use a permanent marker to put a mark on the tubing where it exits the bottle. 2. Remove the bottle vent cap assembly and tubing from the top of the existing solution bottle. 3. Rinse the straw surrounding the tubing with deionized water and shake off any residual water before inserting it into the new solution. This avoids possible contamination. Be sure the tubing extends to the bottom of the straw. If not, adjust it and re-mark the tubing. 4. Insert the straw into the new bottle and screw the vent cap on. Be sure the mark on the tubing is still located where the tubing exits the bottle. This ensures the inner tube has remained at the bottom of the bottle.

Page 29 Startup

Section 35. Place the new bottle in the reagent compartment. Hach recommends changing all the solutions at the same time and does not recommend adding fresh reagent to fill a partially full bottle.

3.3.1 Supplying PowerAfter all appropriate reagents and standards are installed and sample conditioning is prepared, the APA 6000 is ready to start up. Turn on the analyzer by setting the power switch to ON (I). The power switch is located at the center top of the bulkhead that contains the instrument modules (see Figure 13). Close the main door of the analyzer and fasten the latches. The main door should remain closed during operation to maintain correct temperature. Figure 13 Location of the Instrument Power Switch

Section 33.3.2 Priming the AnalyzerNote: Do not allow the instrument to run before installing reagents and standards and providing sample.

After internal checks, the analyzer will begin operation. It is important to prime the analyzer because operating without fluid may damage components. Priming the analyzer ensures that the standards and/or reagents fill the tubing going to the valve module. To prime the analyzer, complete the following steps: 1. Press the MENU key to start from the MAIN MENU. 2. Select SENSOR MENU and press ENTER. 3. Select the sensor by name (default is #1 APA6000) and press ENTER. 4. Select SOLUTIONS & CLEANING and press ENTER. 5. Select PRIMING and press ENTER. 6. Select PRIME ENTIRE SYSTEM NOW. This will prime all the lines from the solution bottles and sample lines. The system prime will take approximately 715 minutes. The analyzer will display various messages about the progress of the cycle. 7. A pop-up window will indicate that priming will begin after the current operation cycle. When priming starts, a pop-up window will indicate the time remaining to complete the prime cycle. 8. When priming is complete, the analyzer will automatically begin measuring sample. The analyzer will require 36 hours for readings to stabilize. During this time, the analyzer will establish temperature control. After readings stabilize, a calibration is required to obtain accurate values. See section 4.2.3.1 on page 44.

Instrument Menus

4.1 The AquaTrend InterfaceThe AquaTrend Interface integrated into the door of the APA 6000 Analyzer provides the interface necessary to communicate with the analyzer (sensor) and the Hach network, if present. The interface provides a numerical or graphical display and a keypad for user input. A remote AquaTrend can be connected for access to the analyzer from another location. The AquaTrend interface can be used with a number of Hach sensors and therefore, not all of the functions available are used when interfacing with the APA 6000. Functions that are not appropriate for the APA 6000 will not be explained fully in the following text. Data can be viewed in numeric or graphical format and reviewed on trend graphs for details of measurement history. With the addition of the Hach Serial I/O Module (see Replacement Parts and Accessories on page 94), data can be downloaded to a computer or printer.

4.1.1 The AquaTrend Interface KeypadThe AquaTrend Interface keypad is designed for simple navigation through the AquaTrend Interface menus (see Figure 14).

4.2.3 Sensor Menu4.2.3.1 CalibrationCalibration prepares the APA analyzer to calculate concentrations in unknown samples based on a calibration generated using two known standards. These two standards are the high and low standard solutions. For immediate trend analysis, an electronic factory default calibration is already established and allows the analyzer to provide approximate measurements.The once-a-day (at 4:00 a.m.)* auto-calibration interval may be changed to every 12 hours, a specific day of the week, or may be turned off. It can also be calibrated on demand as necessary.

* APA6000 Alkalinity and HR Hardness instruments defaults are each Monday at 4:00 a.m. APA6000 HR Hardness instrument default is each Monday at 4:00 a.m. Page 44 Menu Functions


Section 4Reducing the frequency of the auto-calibration will reduce standard usage, but it may also reduce measurement accuracy. Hach recommends that the analyzer be calibrated when any reagent or standard is changed or as often as necessary to achieve acceptable results. Calibration should only be performed after the analyzer has been turned on for more than five hours. This allows the temperature inside the analyzer to stabilize.

Setting Up the Auto-Calibration ScheduleThe analyzer accuracy specifications are based on the factory-set default interval. The APA 6000 Analyzer can calibrate at any time. To change the calibration time, use the auto-cal setup procedure: 1. Press the MENU key to start from the Main Menu. 2. Select Sensor Menu and press ENTER. 3. Select the sensor by name and press ENTER. 4. Select Calibration and press ENTER. 5. Select Auto-Cal Setup and press ENTER. 6. The analyzer calibration is a factory set default interval. In order to change the settings, select one of the following: Select AUTO-CAL to turn the automatic calibration option off, or to set the day or hourly interval you want the instrument to calibrate. Choose any day of the week, every day of the week, or every 12 hours (as shown below). Select Auto-Cal Time to specify the clock hour you want the instrument to calibrate (use a 24-hour clock). Use the up and down arrow keys to enter an hour between 1 and 24. For example, if you want the instrument to calibrate at 2:00 p.m., enter 14.

Note: When auto-calibrate is set to 12 hours, the analyzer calibrates at the set auto-cal time and again 12 hours later.
