Triton TR8 Page vii 1.0 GENERAL DESCRIPTION The Triton TR8 is a nephelometric turbidity analyzer designed for use in water and wastewater. Turbidity, the cloudiness or haziness of a water sample, is caused by particles suspended in the water, typically clay and silt. Since bacteria and viruses can be attached to these particles, turbidity has become a critical indicator of the overall water quality. The Triton TR8 uses an optical method for determining the turbidity, a light beam is directed into the sample where it is scattered by suspended particles in the water. The amount of scattering depends on the amount of material in the water, the wavelength of light used and the size and composition of the suspended particles. The 90° scattered light detection method used by the Triton TR8 sensor is the most common sensor design for turbidity. The Triton TR8 uses a long lived near infrared LED light source (880 nm) and the 90° scattered light method in accordance with ISO 7027 / EN 27027 to assure accurate turbidity values under standardized and comparable conditions. The turbidity value is calculated inside the sensor and digitally transmitted to the Triton TR8 analyzer. The analyzer interprets the signal, displays the turbidity value and transmits the appropriate 4-20 mA output. 1.1 TR8 SENSOR FEATURES The TR8 sensor has a high sensitivity at low levels of turbidity, a simple optical configuration and a balanced sensitivity to all particle sizes. This smart sensor is factory calibrated and ready to use when received. All of the signal processing is performed in the sensor and a noise resistant digital signal is sent to the analyzer/transmitter. A High Range version, (-2), is available for applications with turbidity higher than 500 FNU. Figure 1 Three detectors monitor the light beam at an angle of 90°. The first detector, inside the sensor, (see Figure 1) is the reference detector that compensates for changes in the LED light source (#1) caused by aging or other variations. The second detector (#2) measures a short path length which is best for high concentration measurements. The third detector (#3) measures the longer path length which is best for lower concentrations. The turbidity signal is constantly adjusted versus the reference detector, digital filter functions suppress interfering signals and self monitoring diagnostics assure a highly reliable measurement. An optional mechanical wiper assembly is available to keep the scratch resistant sapphire optical windows clean in dirty applications. The cleaning cycle and duration times are user defined parameters.

The NEMA 4X TR8 Analyzer can be Panel mounted, Wall mounted or Pipe mounted. The base unit is available as a 110 VAC, 220 VAC or 24 VDC powered instrument. The standard configuration has a 250VAC/30VDC 2A contact relay that can be used as an alarm. The single 4-20 mA output is configured for 0-10 FNU, although it can be easily configured for NTU, ppm, mg/l or g/l. Optional configurations with (2) 4-20 mA and/or (4) relays/contacts are available upon request to the factory. 1.2.1 Analyzer Options Part# 1290100-1 1290100-2 1290100-3 1290100-* Page 2 Description Triton TR8 Turbidity Analyzer, 115 VAC, (1) 0/4-20 mA output, (1) Failure Alarm Relay* Triton TR8 Turbidity Analyzer, 230 VAC, (1) 0/4-20 mA output, (1) Failure Alarm Relay* Triton TR8 Turbidity Analyzer, 24 VDC, (1) 0/4-20 mA output, (1) Failure Alarm Relay* Consult factory for optional dual 0/4-20 mA outputs and multiple relays up to (4) additional relays Triton TR8 2.0 INSTALLATION Mount the TR8 in a location where there is easy access to the analyzer and sensors. Install the system in an area where vibrations, electromagnetic and radio frequency interference are minimized or absent. Do not mount in direct sunlight or areas of extreme heat. The TR8 is suitable for outdoor use if mounted with a protective cover or sunshield. 2.1 ANALYZER MOUNTING The Universal Mounting allows the Analyzer to be Wall mounted, Panel Mounted or Pipe/Rail Mounted. The drawings below show the Universal Mounting used with the C-22 analyzer for panel mounting and the Universal Mounting with the T-23 transmitter that uses the same mounting as the C-22 for Pipe/Rail Mounting. The Triton TR8 Analyzer has the same dimensions as the Panel Mounted C-22 Analyzer. 2.1.1 Panel Mounting Figure 2 2.1.2 Pipe Mounting Figure 3 2.2 SENSOR MOUNTING The Triton TR8 turbidity sensor can be installed as an immersion sensor into a tank with the optional Immersion assembly PN 1000223, or in-line with a Flow Through fitting, PN 1000219, or the special Debubbler Flow through fitting designed especially for drinking water applications. Care must be taken when installing the sensor in a pipe or near a tank wall to avoid the back scattering of light which leads to a higher sensor response than expected. The lower the turbidity of the measured Triton TR8 Page 3 solution is the greater the possibility of back scattering. The following graph can be used as an installation guideline. Figure 4 2.2.1 Immersion Assembly The immersion assembly consists of a 1 meter down tube, ¾” FNPT on the process end and a cap with cable feed through on the other. Verify that the sensor is at least 6” from the tank bottom and side walls. The cable is not water proof and under no circumstances should the sensor be suspended in the application by the cable. Figure 5 Page 4 Triton TR8 2.2.2 Flow-Through Assembly Conventional turbidity measurements are carried out in an unpressurized sample. When the pressure on a sample (which was pressurized beforehand) is released, fine bubbles are produced which distort the turbidity measurement. The pressure must remain constant or rise as the water moves from a pipe and into the flow cell in order to minimize the formation of air bubbles. The outfall from the flow cell must not create a low pressure in the flow cell by siphoning the sample to drain, see examples below. If air bubbles cannot be eliminated then the mechanical wiper assembly can help remove the bubbles that form on the measurement windows, otherwise use the De-Bubbler Assembly below. Figure 6: Proper Installation examples to avoid bubble formation. Figure 7: Sensor alignment in flow cell with optional spray cleaner and without. Triton TR8 Page 5 Figure 8: Dimensional Drawing of the Flow-Through Assembly with optional union adapters 2.2.3 De-Bubbler Flow Assembly When air bubbles are present in the sample the De-Bubbler Flow assembly effectively removes them from the sample. The lower half of the incoming sample flow is diverted down the central tube (1) to the “Ring Channel” where air bubbles can escape through the outlets, (2), upwards to the exiting sample flow. Bubble free water is pushed through the tubes, (3), into the measuring Chamber, (5). The design facilitates a high flow rate by the TR8 sensor, (6), that optimizes response time and minimizes sedimentation forming in the chamber. A large drain plug, (4), aids in flushing any sediment that does deposit in the chamber. Figure 9: De-Bubbler Flow Cell Diagram Page 6 Figure 10: Dimensional Drawing, De-Bubbler Assembly Triton TR8 2.3 WIRING The various cables, measurement signal, outputs and power, enter the Triton TR8 instrument through the three cable glands on the bottom of the instrument. Only properly trained personnel should attempt to wire the instrument. 2.3.1 Sensor Wiring The Triton TR8 sensor uses a digital communication protocol that allows the sensor to be placed up to 200 meters from the analyzer. The TR8 Sensor is supplied with either a 7 meter or 15 meter cable. Installation at distances greater than 15 meters requires the use of an extension cable, PN 9640004.cond and Junction Box, PN 1000222.

For clear media (measured value below 1000 NTU) always set the gas bubble barrier to 100 %. B9 Enter gas bubble barrier Display Information 3.3.3 CURRENT INPUT To use the "Current input" function group, you need a relay board with current input which is Not Part of the Basic Version. With this function group you can monitor process parameters and use these for feed forward control. For this purpose, you must connect the current output of an external measured variable (e.g. flow meter) to the 4 to 20 mA input of the transmitter. The following assignment applies: Flow in main stream Flow meter start of measuring range Flow meter end of measuring range Current signal in mA 4 20 Current input signal in % 0 100 Monitoring of flow in main stream This arrangement is particularly practical if the sample flow through a flow assembly in an open outlet is completely independent of the flow in the main stream. This permits signaling of an alarm condition in the main stream (flow too low or has completely stopped) and triggers dosing switch-off even if the medium flow is retained due to the method of installation. **The Basic Version Does Not Include Functions in Italics** Selection or Range Default in Bold Coding Field Z CURRENT INPUT function group Current input settings. Z1 Select flow monitoring of main stream (with controller switchoff) Flow monitoring may only be switched on if the flowmeter is connected in the main stream.

In the case of a controller, a delay until a representative measured value is received is useful if the flow fails for an extended period. 0 to 100% corresponds to 4 to 20 mA at the current input. Observe measured value assignment to the current output of the flow meter. The controller is switched off if the value entered in Z4 is undershot or overshot. If Z6 = off, the field Z7 is not available. Z6 = basic: disturbance variable only affects the basic load (alternatively dosing in proportion to quantity can be used if usual PID controlling is not possible, due to a defective sensor, for example). When the value is set, the controller actuating variable is the same size when feed forward control is switched on as when feed forward control is switched off. 3.3.4 CURRENT OUTPUT Use the "Current output" function group to configure the individual outputs. You can enter either a linear characteristic (O3 (1)) or you can simulate a current output value (O3 (2)) to check the current outputs. In addition, a user-defined current output Table (O3 (3)) is available with the Plus Package. If a second current output is present, you can output the controller actuating variable in accordance with field R 237 via the current output. Exception: if you have chosen a "continuous controller" for current output 2, you cannot enter a user-defined current output Table on current output 1. In a User Defined Output Table, the variable must steadily increase across the table or decrease, the variable cannot change direction. The distance per mA (SV/mA) between two table values must be greater than: 0.005 FNU, 0.005 NTU, 0.005 ppm, 0.005 mg/l, 0.005 %, 0.05 g/l or 0.25 C°. Triton TR8 Page 17 The values for the sample characteristic are entered in the following table. The distance per mA can be calculated from Δ signal / Δ mA.

This selection must be made even if all error reporting is switched off in F5. Caution! If "0-20 mA" was selected in O311, "2.4 mA" may not be used. Here you can select all the errors which should trigger an alarm. The errors are selected via the error numbers. Please refer to the table in section 6.2 "System error messages" for the meaning of the individual error numbers. The factory settings remain in effect for all errors not edited. If “no” is selected, all the other alarm settings are deactivated (e.g. alarm delay). The settings are retained. This setting only applies to the error selected in F5. The option selected in F4 is effective or ineffective in the event of an error. This setting only applies to the error selected in F5. This field is not available for certain errors, see "Troubleshooting and fault elimination" section. If ←R is selected, you return to F, if next is selected, you go to F5. 3.3.6 CHECK The CHECK function group is only available for devices with a Plus Package. In the CHECK function group, you can select different monitoring functions for the measurement. Triton TR8 Page 21 All monitoring functions are off by default. To adapt the Sensor Check System to the current application conditions, add and set the suitable functions. Alarm threshold monitoring (fields P1 to P4) You can use this function to monitor the measured value for permissible upper and lower limits and trigger an alarm (E154, E155). PCS alarm (Process Check System), (fields P5 to P8) AC (Alternating Check): The function AC (field P5) is used to check measuring signals for deviations. If the measuring signal does not change within an hour an alarm (E152) is triggered. The reason for such sensor behavior can be contamination, cable rupture or similar. CC (Controller Check): You can monitor the controller activity with the function CC. This function is mainly used for batch processes and single-sided limit switches. A malfunction of the controller is detected and reported thanks to freely adjustable monitoring times (E156 - E157). The CHECK Function group is an optional package; the BASIC package does not include items listed in Italics.

This function is mainly used for batch processes and single-sided limit switches. 3.3.7 RELAY To use the RELAY function group, you need a relay board which is not part of the basic version. The following relay contacts can be selected and configured as desired (max. four contacts, depending on options installed): • Limit contactor for measured turbidity value: R2 (1) • Limit contactor for temperature: R2 (2) • PID controller: R2 (3) • Timer for cleaning function: R2 (4) • Chemoclean function: R2 (5) 3.3.7.1 Limit contactor for measured turbidity value and temperature The transmitter has different ways of assigning a relay contact. Switch-on and switch-off points and pick-up and drop-out delays can be assigned to the limit contactor. In addition, you can configure an alarm threshold to output an error message and to start a cleaning function in conjunction with this. These functions can be used both for turbidity measurement and for temperature measurement. Triton TR8 Page 23 Please refer to Fig. 28 for a clear illustration of the relay contact states. • When the measured values increase (maximum function), the relay contact is closed as of t2 after the switch-on point (t1) has been overshot and the pick-up delay has elapsed (t2 - t1). The alarm contact switches if the alarm threshold (t3) is reached and the alarm delay (t4 - t3) has also elapsed. • When the measured values decrease, the alarm contact is reset when the alarm threshold (t5) is undershot as is the relay contact (t7) after the drop-out delay (t7 - t6). • If the pick-up and drop-out delays are set to 0 s, the switch-on and switch-off points are also switch points of the contacts. Settings can also be made for a minimum function in the same way as for a maximum function. Figure 16: Illustration of the alarm and limit value functions A. Switch-on point > switch-off point: Max. function B. Switch-on point < switch-off point: Min. function 1. Alarm Threshold 2. Switch On Point 3. Switch Off Point 5. Alarm On 6. Alarm Off 7. Contact Off 4. Contact On 3.3.7.2 PID Control You can define various controller functions for the transmitter. On the basis of the PID controller, P, PI, PD and PID controllers can be implemented. For an optimum control system, use the controller that best Page 24 Triton TR8 suits your application. Depending on the option selected in the R 237/R 266 field, the actuating signal can be output via relays or via current output 2 (if available). • P controller: Used for simple linear control purposes with small system deviations. Where major changes are to be controlled, overshooting may occur. In addition, a lasting control deviation is to be expected. • PI controller: Is used for control systems where overshooting is to be avoided and no lasting control deviation should occur. • PD controller: Is used for processes that require quick changes and where peaks are to be corrected. • PID controller: Is used for processes where a P, PI or PD controller does not control sufficiently. Configuration options of the PID controller The following configuration options are available for a PID controller: • Change control gain Kp (P influence) • Set integral action time Tn (I influence) • Set derivative action time Tv (D influence) Basic load dosing (Basic) The basic load dosing (field R231) is used to set a constant dosage (field R2311) PID controlling plus basic load dosing If you select this function (PID + Basic) in field R231 the PID controlled dosage will not be lower than the basic load value entered in field R2311. Commissioning If you do not yet have any experience for setting the control parameters, set the values that yield the greatest possible stability in the control circuit. Proceed as follows to optimize the control circuit further: • Increase the control gain Kp until the controlled variable just starts to overshoot. • Reduce Kp slightly and then reduce the integral action time Tn so that the shortest possible correction time without overshooting is achieved. • To reduce the response time of the controller, also set the derivative action time Tv. Triton TR8 Page 25 Fig17: Optimization of settings Tn and Kp A. Actual value B. Time 1. Tn too small 2. Tn too large 3. Kp too large 4. Kp too small 5. Optimum setting Actuating signal outputs (R237 ... R2310) Each control contact outputs a cyclical signal whose intensity corresponds to the controller's manipulated variable. A distinction is made according to the type of signal cycle: • Pulse length modulation The bigger the calculated manipulated variable is, the longer the contact affected remains picked up. The period T can be adjusted between 0.5 and 99 s (field R238). Outputs with pulse length modulation are used to activate solenoid valves. • Pulse frequency modulation The bigger the calculated manipulated variable is, the higher the switching frequency of the contact affected. The maximum switching frequency 1/T can be set between 60 and 180 min-1. Page 26 Triton TR8 The on-time tON is constant. It depends on the set maximum frequency and is approx. 0.5 s for 60 min-1 and approx. 170 ms for 180 min-1. Outputs with pulse frequency modulation are used to activate directly controlled solenoid dosing pumps. Constant controller Via the current output 2, the minimum actuating variable (0 %) of the controller is output with 0/4 mA and the maximum actuating variable (100%) of the controller is output with 20 mA. Control characteristic for direct and inverse control action You can choose between two control characteristics in the R236 field: • Direct control action = maximum function • Inverse control action = minimum function 3.3.7.3 Timer for cleaning function This function includes a simple cleaning option. You can set the time interval after which cleaning should start. So you can only select a constant interval sequence. Other cleaning functions are available for selection in conjunction with the Chemoclean function (version with four contacts, see "Chemoclean function" section). Note! Timer and Chemoclean do not work independently of one another. While one of the two functions is active, the other cannot be started.

Active t0 Normal Mode t1 Start Cleaning t2-t1 Cleaning Time t3-t2 Hold Dwell Time t4-t3 Time between Cleaning cycles Triton TR8 Page 27 3.3.7.4 Chemoclean function Just like the timer function, Chemoclean can also be used to start a cleaning cycle. However, Chemoclean also gives you the added option of defining different cleaning and rinsing intervals. As a result, it is possible to clean irregularly with different repeat cycles and to separately set the cleaning times with post rinse times. Note! • To use the Chemoclean function the transmitter has to be equipped with a designated relay board (see product structure or chapter "accessories"). • Timer and Chemoclean do not work independently of one another. While one of the two functions is active, the other cannot be started. • For the Chemoclean function, the relays 3 (water) and 4 (cleaner) are used. • If cleaning is prematurely aborted, a post rinse time always follows. • If the setting is "Economy", cleaning only takes place with water.

The calibration data are saved in an EEPROM directly in the sensor. For this reason: • Recalibration is not required in the event of a power failure • Recalibration is not required when the transmitter is replaced • Customer-specific recalibration is required, however, when the sensor is replaced Three calibration data records are saved in the sensor for each of the four main operating modes. Factory data record no. 1 not changeable User data record no. 2 changeable User data record no. 3 changeable Page 38 FNU/NTU ppm or mg/l g/l Formazine SiO2 Activated sludge Formazine Kaolin Activated sludge Formazine SiO2 Activated sludge % Residual concrete water Residual concrete water Residual concrete water Triton TR8 Select the desired data record in the SETUP 2 function group in the B4 field. • In the FNU operating mode, the sensor is factory calibrated with formazine traceable to ISO 7027. • In the ppm operating mode, the calibration data records for Kaolin and SiO2 are derived from the FNU data records. • In the % operating mode, the calibration data records are set to the average of various residual concrete waters. They are preset in such a way that correct values are displayed for average clarity. However the settings do not follow a standard currently applicable. • In the g/l operating mode also, the sensor is not calibrated to a fixed value as no standard is directly applicable. You must carry out a calibration because the media of the various applications differ too greatly here. Three-point sensor calibration is the standard calibration. It is absolutely essential: • When commissioning the sensor in sludge applications • When changing to another sludge type Three-point sensor calibration is not necessary: • When commissioning the sensor in the drinking water area (sensor has been calibrated for drinking water applications in the factory). • For residual concrete water. Density measurement for determining the concentration of residual concrete water is based on %–data records. They are preset in such a way that correct values are displayed for average clarity. One-point calibration is often sufficient to adjust the system in the event of deviating values. • When recalibrating with the same sludge type. One-point calibration suffices here if the degrees of lightness and clarity, for example, do not differ too greatly. Note! • Sludge samples tend sediment. Mix the sample well, even during the calibration process, but not to the extent that gas bubbles are formed. • The sensor has to be far enough away from the floor and the wall of the calibration vessel during calibration. The immersion depth must be at least 40 mm. • The characteristic determined during the calibration is stored in the selected data record (Setup 2, B4 field). • Calibration is not possible if data record 1 is selected with the factory setting. • If the calibration data deviate from the standard values by a factor of two or more, a warning (E084) is output. The calibration results are accepted. • If the calibration results are outside the permitted range, a calibration error (E045) is indicated. The calibration results are not accepted. • For every type of calibration, the installation adjustment and the offset are reset to zero and the slope to 1.0. Calibration Menu Options 3–Pt Three-point calibration Corr Three-point correction Edit Edit calibration Refl Installation adjustment 1–Pt One-point calibration Triton TR8 Page 39 Data Calibration data Three-point calibration (3–Pt) You should perform the calibration in the turbidity/solids concentration range in which you plan to measure. The overall calibration characteristic of the measuring chain is determined using three samples of known turbidity or known solids content. Calibration with a very dark, high-absorption medium returns a small slope while light, clear media return big slopes. You can create the requisite probes by diluting a medium sample. In general, very good calibration results are achieved with a concentration gradation of 10 %, 33 % and 100 %. The following condition must be met for the calibration: Sample A > 1.1 x sample B > 1.1 x sample C Figure 20: Preparing 3 point calibration samples A Original Sample B 1 part A + 2 parts water C 1 part A + 9 parts water A different dilution ratio should be selected for very high-absorption media to achieve accurate calibration results. Instead of 100 % – 33 % – 10 %, you can use dilution ratios of 100 % – 20 % – 5 % or 100% – 10 % – 3.3 %. If the scattered light of a light sample hits a sensor that is calibrated for a dark medium, it can happen that the signal value is so high that it is above the calibration curve. Three-point correction (Corr) If the calibration was performed with an unknown sample concentration but with a defined dilution, the correct value determined afterwards in the laboratory is entered here. Edit calibration (Edit) If each of the samples has been determined afterwards in the laboratory, the correction for the calibration is entered here. Installation adjustment (Refl) In installation adjustment, backscatter from the immediate sensor environment is compensated. Installation adjustment must be performed with a medium lower than 2 FNU or 5 ppm. Page 40 Triton TR8 One-point calibration (1–Pt) In the area of TS/concentration measurement, one-point calibration is used to change the conversion factor (field C166). The slopes are not changed. In the FNU range, the two slope values are adjusted by a one-point calibration. This is possible because the conversion factor in the FNU range is always 1 and the editing range is limited to 4000 FNU. In this way, the two curves are always increasing and the calibration remains clear. In the ppm range, the slope values are adjusted up to 500 ppm. For higher values, the conversion factor is changed. Calibration data (Data) Here, you can display the calibration points 1 to 3, slope 1 and 2 and the conversion factor. With three-point calibration, the curves used in the algorithm are adjusted as precisely as possible using the data points acquired. The difference between the ideal curve of the algorithm and the three actual calibration points can be found as a correction factor in the C161, C162 and C163 fields of the data function. The correction values are indicated in %. The values should be as close to 100 % as possible. Values from 70 to 80 % are acceptable. 50 % in one or two calibration points clearly indicates a problematic calibration. A warning (E084) is output here for this reason. This can mean that significant deviations can occur between the calibration points. The calibration points themselves are always retrieved correctly. 3.4.1 CALIBRATION Coding Field C Function group CALIBRATION Selection or Range Default in Bold Display Information Calibration settings. 3-Pt = Three-point calibration (1) Corr = Three-point correction (2) Edit = Edit calibration (3) Refl = Fitting with reflection compensation (4) 1-Pt = Single-point calibration (5) Data = Calibration data (6) For data set 1 (B4), only the “Data” function is accessible.

For this, specify the maintenance times in an operations logbook or operations calendar. The following tasks must be carried out: • Cleaning the transmitter • Checking the measuring function • Cleaning the sensor • Recalibration 4.1 CLEANING THE TRANSMITTER Clean the front of the housing with usual commercial cleaning agents. In accordance with DIN 42 115, the front is resistant to: • Isopropanol • Diluted acids (max. 3%) • Diluted alkalis (max. 5%) • Esters • Hydrocarbons • Ketones • Household cleaners Caution! For cleaning purposes, never use: • Concentrated mineral acids or alkalis • Benzyl alcohol • Methylene chloride • High-pressure steam 4.2 CHECKING THE MEASURING POINT 4.2.1 Transmitter The TR8 Turbidity sensors cannot be simulated as they contain the complete data processing and all the measured values are transmitted to TR8 Analyzer using the digital interface RS 485. Therefore a functional sensor is required for the measuring point test. Method for testing a measuring point: • Check that device is operable and that the display reacts appropriately, e.g. by pressing the PLUS key. • Check the current outputs by carrying out a current simulation (Field O3 (2)). • Measure the sensor operating voltage: approx. 10 to 16 V at terminals 87 (+) and 88 (–). • The cause for an incorrect voltage may be present either at the device or at the sensor. – Replace the sensor. – If the sensor operating voltage is still too low replace the power supply module (The analyzer must be returned to the factory for power supply replacement). Page 48 Triton TR8 • Sensor operating voltage is o.k. but no measured turbidity value even with a new sensor. Replace the transmitter module (The analyzer must be returned to the factory for power supply replacement). 4.2.2 Triton TR8 Sensor 1. Remove the sensor from the medium. 2. Clean and dry the sensor. 3. Check the slope using CUY22 check unit. A stable measured value (between 2 and 6 FNU) must register. The exact value is not of importance but must be repeatable for the same sensor. 4.3 CLEANING THE SENSOR Contamination of the sensor can impact the measurement up to the point that measurement no longer functions, e.g. by: • Thick film build-up on the sensor optics. Film build-ups can cause bad measurement results. • Wiper clogging. This causes bad measurement results. The sensor must be cleaned regularly to ensure reliable measurement. The frequency and intensity of the cleaning depend on the medium. The sensor must be cleaned: • Prior to every calibration • Regularly during the operation • Prior to returning the sensor for repair. 4.4 RECALIBRATION After cleaning check the Triton TR8 in the Calibration Cap the reading should be between 2FNU and 6 FNU. If not then you have the following options in the ''Calibration'' menu of the transmitter: • One-point calibration • Three-point calibration • Installation adjustment • Correction function • Adjust calibration data If you are unable to recalibrate the sensor then the sensor must be replaced. When replacing a sensor pay attention to the following: • Replacing the Triton TR8 sensor All factory calibration data are saved in the sensor. The sensor and the assembly are calibrated together. No additional calibration is required for applications with pure or ultrapure water, if the sensor and the Triton TR8 Page 49 assembly are replaced together. The calibration data of the sensor are automatically transferred to the measuring instrument. 5.0 ORDERING INFORMATION Part# Description Triton TR8 Turbidity Sensor with 7 meter cable 1398000-1 Triton TR8 Turbidity Sensor High Range with 7 meter cable 1398000-2 Triton TR8 Turbidity Sensor with 15 meter cable 1398001-1 Triton TR8 Turbidity Sensor High Range with 15 meter cable 1398001-2 Triton TR8 Turbidity Sensor with 7 meter cable & Automatic Wiper 1398010-1 Triton TR8 Turbidity Sensor High Range with 7 meter cable & Automatic Wiper 1398010-2 Triton TR8 Turbidity Sensor with 15 meter cable & Automatic Wiper 1398011-1 Triton TR8 Turbidity Sensor High Range with 15 meter cable & Automatic Wiper 1398011-2 Triton TR8 Turbidity Sensor with 7 meter cable & Flow Through Assembly 1398100-1 Triton TR8 Turbidity Sensor with 15 meter cable & Flow Through Assembly 1398101-1 Triton TR8 Turbidity Sensor with 7 meter cable, Automatic Wiper & Flow Through Assembly 1398110-1 Triton TR8 Turbidity Sensor with 15 meter cable, Automatic Wiper & Flow Through Assembly 1398111-1 Triton TR8 Turbidity Sensor with 7 meter cable & De-Bubbler Assembly 1398200-1 Triton TR8 Turbidity Sensor with 15 meter cable & De-Bubbler Assembly 1398201-1 Triton TR8 Turbidity Sensor with 7 meter cable, Automatic Wiper & De-Bubbler Assembly 1398210-1 Triton TR8 Turbidity Sensor with 15 meter cable, Automatic Wiper & De-Bubbler Assembly 1398211-1 (-1) Low Range Sensor < 500 FNU, (-2) High Range Sensor > 500 FNU 5.1 ACCESSORIES Part # 1000223-1 2000268 3200266 1000219 9640004.cond 1000222-2 1000228-1 1000227 Page 50 Model and Description Immersion Assembly ( Cap/Cable feed-through, 1 meter down pipe) Rail Moun3ng Brackets, (2) Quick Release “U” clamps for 2” Guard Rail moun3ng Wall Moun3ng Bracket Flow Through Housing TR8 5 Conductor Cable, per ft.
