DESCRIPTION AND SPECIFICATIONS
1.1 FEATURES AND APPLICATIONS
MODEL 54eA ANALYZER
The Model 54eA analyzer can be used with the TCL sample conditioning system and 499ACL-02 sensor for the continuous determination of chlorine in water.
The Model 54eA analyzer is housed in a rugged NEMA 4X weatherproof, corrosion resistant enclosure of epoxy­painted aluminum. It is suitable for panel, pipe, or wall mounting. Operation of the analyzer is through a front panel membrane keypad. The large back-lit dot matrix display continuously indicates chlorine concentration in large numerals along with temperature, current output, and two programmable process parameters, such as alarms or diagnostic variables. Menu screens for calibrating and programming the analyzer are simple and intu­itive. Plain language prompts in English, Spanish, Italian, German, or French guide the user through instrument configuration and sensor calibration
The Model 54eA is a member of the Rosemount SMART FAMILY®of instruments. It is designed to communicate with the Model 375 HART®communicator or any host that supports the HART communication protocol.
Two independent isolated outputs provide either a 0-20 mA or 4-20 mA output and can be assigned to chlorine or temperature. The controller option allows PID control acting on chlorine or temperature.
Three, fully programmable process alarms are standard. One relay can be configured as an interval timer. An overfeed timer is available for any one process relay, and one relay can also be used as an interval timer. The TPC option allows any alarm relay to be used for Time Proportional Control.
The analyzer fully compensates chlorine readings for changes in membrane permeability caused by temperature changes.
For additional information, see Product Data Sheet 71-54e.
MODEL 499A CL-02 SENSOR
The Model 499ACL-02 total chlorine sensor is used in the TCL sample conditioning system. Although the sensor is called a chlorine sensor, it really measures iodine. The iodine comes from the reaction between halogen oxidants in the sample and the acetic acid/potassium iodide reagent added by the sample conditioning system.
The sensor consists of a gold cathode and a silver anode in an electrolyte solution. A silicone membrane, permeable to iodine, is stretched over the cathode. The analyzer applies a voltage to the cathode sufficiently negative to reduce all the iodine reaching it. Because the concentration of iodine in the sensor is always zero, a concentration gradient continuously forces iodine from the sample through the membrane into the sensor.
The reduction of iodine in the sensor generates a current directly proportional to the diffusion rate of iodine through the membrane, which is directly proportional to the concentration of iodine in the sample. Because the iodine concentration depends on the amount of total chlorine in the sample, the sensor current is ultimately proportional to the total chlorine concentration.
The permeability of the membrane to iodine is a function of temperature. A Pt100 RTD in the sensor measures the temperature, and the analyzer uses the temperature to compensate the total chlorine reading for changes in membrane permeability.
Sensor maintenance is fast and easy. Replacing the membrane requires no special tools or fixtures. Simply place the membrane assembly on the cathode and screw the retainer in place. Installing a new membrane and replenishing the electrolyte takes only a few minutes.

SECTION 2. PRINCIPLES OF OPERATION
MODEL TCL SECTION 2
PRINCIPLES OF OPERATION
Total chlorine by definition is the iodine pro­duced in a sample when it is treated with potassium iodide at a pH between 3.5 and 4.5. Typically, acetic acid (or vinegar) is used to adjust the pH.
The total chlorine analyzer consists of a sam­ple conditioning system, which injects the reagent into the sample, and a sensor and analyzer, which measure the amount of iodine produced. Figure 2-1 shows the sample condi­tioning system. The sample enters the sample conditioning enclosure and flows to an over­flow sampler from which the sample pump takes suction. Excess sample drains to waste. At the same time, the reagent pump draws reagent, a solution of potassium iodide in vine­gar, from the reagent carboy and injects it into the suction side of the sample pump. The sam­ple and reagent mix as they pass through the pump, and total chlorine in the sample is con­verted to the chemically equivalent amount of iodine. The flow rates are 11 mL/min for the sample and 0.2 mL/min for the reagent.
The treated sample next enters the flow cell. Bubbles injected into the flow cell produce turbulence, which improves the stability of the reading. A membrane-covered amperometric sensor in the flow cell measures the concentration of iodine. The analyzer receives the raw signal from the sensor and displays the concentration of total chlorine. Display units are ppm (mg/L) chlorine as Cl2. The treated sample leaves the flow cell and drains to waste along with the excess sample.

INSTALLATION
3.2.3 Install the Sample Conditioning Enclosure
1. Refer to Figures 3-6 and 3-7 for installation details.
2. Connect the sample line to the sample conditioning system. Use ¼-inch OD hard plastic or stainless steel tub­ing. If dechlorinated water is being measured, provide a way of substituting a chlorinated water sample for the dechlorinated sample. Chlorinated water is needed to calibrate the sensor and to check its response.
3. If a grab sample tap is not already available, install one in the process piping. Choose a point as close as pos­sible to the sample line supplying the TCL. Be sure that opening the sample valve does not appreciably alter the flow of sample to the instrument.
4. Connect the drain to a length of ¾-inch ID flexible plastic tubing. The sample must drain to open atmosphere.
5. Find the reagent tubing and fitting in the plastic bag taped to the inside of the enclosure door. Screw the reagent fitting onto the bulkhead fitting at the bottom left of the enclosure. Pass the reagent tubing through the hole in the carboy cap. Be sure the plastic weight will be inside the carboy when the cap is placed on the car­boy. Attach the reagent tubing to the barbed connector. See Figure 3-8.
6. Place the blue plastic carboy beneath the enclosure. Place the weighted end of the reagent tubing inside the carboy. To prepare reagent, see Section 5.2.
3.2.4 Install the Sensor
1. From inside the sample conditioning enclosure, thread the sensor cable through the gland on the upper left side. Leave about one foot of cable inside the enclosure.
2. Wire the sensor to the analyzer. Refer to Section 4.3.
3. Remove the nut and adapter from the flow cell. Slip the nut over the end of the sensor. Thread the adapter onto the sensor. Hand tighten only. Remove the protective cap from the end of the sensor.
4. Insert the sensor in the flow cell. Hand tighten the nut.

4.1 GENERAL
WARNING
Electrical installation must conform to the National Electrical Code, all state and local codes, and all plant codes and standards for electrical equipment. Electrical installation and wiring must be done by qualified personnel.
The five holes in the bottom of the instrument case accept 1/2-in. strain relief connectors or conduit fittings. The rear openings are for power and alarm relay wiring. The left front opening is for sensor wiring and the right front opening is for analog output wiring. Seal unused openings with conduit plugs.
4.2 PROVIDE POWER TO THE SAMPLE CONDITIONING SYSTEM
NOTE
Provide a switch or breaker to disconnect the sample conditioning cabinet from the main power supply. Install the switch or breaker near the unit and identify if as the disconnecting device for the sample conditioning system.
1. Be sure the pump switches on the wiring access panel are in the off position.
2. Remove the four screws securing the wiring access panel. Pull the panel out of the way to reveal the power terminal strip.
3. Insert the power cable through the strain relief connection labeled power (see Figure 3-7). Wire the power cable to the terminal strip as shown in Figure 4-1. Do not apply 230 Vac power to a 115 Vac TCL (Model option -11). Doing so will damage the instrument.
4. Leave the pump power switches
off until ready to start up the unit.
See Section 5.
NOTE
The Model 54eA analyzer leaves the factory configured for use with the Model 499ADO oxygen sensor. Because a 499ADO sensor is NOT used in the TCL system, turn to Section 7.5 and configure the analyz­er to read total chlorine before wiring the sensor to the analyzer. Operating the analyzer and sensor for longer than five minutes while the analyzer is improperly configured will greatly increase the stabilization time for the sensor.
Be sure to turn off power to the analyzer before wiring the sensor.

4.3 MAKE POWER, ALARM, OUTPUT AND SENSOR CONNECTIONS IN THE ANALYZER
Refer to Figure 4-2. Make power and alarm connections on TB3. Make analog output wiring connections on TB2. For access to power and alarm terminals, loosen the screw holding the protective cover in place and remove the cover.
DANGER
Live voltages may be present. Will cause severe injury or death.
Alarm contacts are dry (i.e., not powered) and are normally open. Refer to Section 1.0 for relay specifications. For best EMI/RFI protection, shield the output cable and enclose it in an earth-grounded, rigid, metal conduit.
Connect the outer shield of the output cable to the earth ground connection on TB2 (see Figure 4-2). Keep sensor and output signal wiring separate from power wiring. Do no run sensor and power cables in the same
conduit or close together in a cable tray. AC wiring must be 14 gauge or greater. Be sure to connect earth ground from the power cable to the nearby
ground lug. A good earth ground is necessary for proper operation of the controller. Provide a switch or breaker to disconnect the analyzer from the main power supply. Install the switch or breaker near the analyzer and label it as the disconnecting device.
WARNING: RISK OF ELECTRICAL SHOCK
AC connections and grounding must comply with UL 508 or local electrical code. DO NOT apply power to the analyzer until all electrical connections are verified and secure.
NOTE
The Model 54eA analyzer leaves the factory configured for use with the Model 499ADO oxygen sensor. Because a 499ADO sensor is NOT used in the TCL system, turn to Section 7.5 and con­figure the analyzer to read total chlorine before wiring the sensor to the analyzer. Operating the analyzer and sensor for longer than five minutes while the analyzer is improperly configured will greatly increase the stabilization time for the sensor.
Be sure to turn off power to the analyzer before wiring the sensor.
The wiring label, which is shown in Figure 4-3, is a general purpose label. It has wiring information concerning other sensors, for example, contacting and inductive conductivity sensors, that can be used with the 54e instru­ment platform. For total chlorine measurements, only TB3 is used.
Refer to Figures 4-4 and 4-5 for sensor wiring. Use the pigtail wire and wire nuts provided with the sensor when more than one wire must be attached to a single terminal

START-UP
SECTION 5. START-UP
5.1 PREPARE THE REAGENT
1. DO NOT PREPARE THE SOLUTION UNTIL READY TO USE.
2. Position the blue plastic carboy under the sample conditioning cabinet. Unscrew the cap and reagent tube assembly.
3. Add the potassium iodide reagent to the carboy. See the table.
4. Add five gallons (19 L) of distilled white vinegar one gallon (4 L) at a time. Swirl the carboy after each addition
5. Screw the cap on the carboy. Be sure the reagent uptake tube extends to the bottom of the carboy.
6. Connect the reagent tube to the small fitting on the bottom left hand side of the enclosure.
NOTE
The shelf life of the potassium iodide vinegar solution is at least two months if stored in the blue carboy. Do not store the reagent in a container other than the blue carboy. The reagent is sensi­tive to sunlight, which the blue carboy effectively blocks.
5.2 ZERO THE SENSOR
1. Place the sensor in a beaker of deionized water or simply place the sensor in air.
2. Let the sensor operate until the sensor current is stable, then zero the sensor. See Section 8.3.2 for detailed instructions.
5.3 START SAMPLE FLOW
Adjust the sample flow until a slow stream of liquid is running down the inside tube of the sampling cup.
5.4 BEGIN OPERATION AND CALIBRATE THE SENSOR
1. Turn on the reagent and sample pump switches. Observe that liquid begins to fill the flow cell. The sample flow is about 11 mL/min, so the flow cell will fill rather slowly. Also observe that the air pump is operating. The pump will produce very vigorous bubbling in the flow cell.
2. Once the flow of reagent starts, it takes about two minutes for the reagent to reach the flow cell. If the con­centration of total chlorine in the sample is greater than about 0.5 ppm, the treated sample in the flow cell will be pale yellow. Sample containing more chlorine will be dark yellow.
3. Monitor the sensor current. Once the reading is stable, calibrate the unit. See Section 9.3.3 for detailed instruc­tions. It may take thirty minutes or longer for the reading to stabilize when the sensor is first put in service.
WARNING
The reagent contains potassium iodide dissolved in distilled vinegar or 5% acetic acid. Avoid contact with skin and eyes. Wash thoroughly after using.

6.4 ALARM STATUS
Green LEDs (labeled 1, 2, and 3) indicate when alarm relays 1, 2, and 3 are energized. The fourth relay indi­cates a fault condition. When a fault occurs, the red LED (labeled FAIL) lights up, a descriptive error mes­sage appears, and the outputs and alarm relays act as described in Section 7.6 and Section 7.7 under fault value.
The red LED also indicates when the interval timer rou­tine is activated and when the time limit has been reached on a feed limit timer. For more information on these subjects, see Section 7.7.
FIGURE 6-1. Configuration of Outputs
for Total Chlorine
Outputs can be assigned to total chlorine or to temperature. The outputs can be configured as either linear (4-20 mA) or PID outputs.
FIGURE 6-2. Main Display Screen
The total chlorine measurement is always displayed con­tinuously in large numerals. The temperature and output current are always displayed on the second line of the main display. The third line can be configured by the user. In the example, the third line shows the alarm 1 setpoint and the total chlorine sensor current in nA.
