46 MODEL TCL SECTION 9 CALIBRA TION - TOT AL CHLORINE SECTION 9 CALIBRA TION - T OT AL CHLORINE 9.1 INTRODUCTION The continuous determination of total chlorine requires two step s. See Figure 9-1. First, the sample flows into a conditioning system (Model TCL) where it is treated with acetic acid (vinegar) and pot assium iodide.
1. Place the sensor in a beaker of dionized water . 2. Let the system run until the sensor current is stable. The sensor current will drop rapidly at first and then grad- ually reach a stable zero value. T o monitor the sensor current, go to the main display .
48 1. If the sensor was just zeroed, place the sensor back in the flow cell. Confirm that excess sample is flowing down the inside tube of the overflow sampler . Also, verify that reagent is being delivered to the sample and the air pump is working. 2.
MODEL TCL SECTION 9 CALIBRA TION - TOT AL CHLORINE 9.4 DUAL SLOPE CALIBRA TION Figure 9-3 shows the principle of dual slope calibration. Between zero and con- centration C1, the sensor response is linear . When the concentration of chlo- rine becomes greater than C1, the response is non-linear .
50 MODEL TCL SECTION 9 CALIBRA TION - TOT AL CHLORINE 7. Once the reading is stable, the screen at left appears. Sample the process liquid. Make a note of the reading before taking the sample. Immediately determine total chlorine. Note the controller reading again.
MODEL TCL SECTION 10 CALIBRA TION - CURRENT OUTPUTS SECTION 10 CALIBRA TION - CURRENT OUTPUTS 10.1 INTRODUCTION Although the controller outputs are calibrated at the factory , they can be trimmed in the field to match the reading from a standard current meter .
52 MODEL TCL SECTION 1 1 PID AND TPC CONTROL SECTION 1 1 PID AND TPC CONTROL 1 1.1 PID CONTROL (CODE -20) PID Control The Model 54eA current outputs can be programmed for PID control. PID control is used with a control device that is capable of varying it s output from 0 to 100 percent in response to a changing signal in mil- liamps.
MODEL TCL SECTION 1 1 CALIBRA TION - CONTROL Proportional (Gain) Plus Integral (Reset) For the automatic elimination of deviation, I (Integral mode), also referred to as Reset, is used. The propor- tional function is modified by the addition of automatic reset.
54 MODEL TCL SECTION 1 1 CALIBRA TION - CONTROL 6. When sufficient data have been collected, return the output signal to its original value using the sim- ulate test function. Maintain the controller in this manual mode until you are ready to initiate auto- matic PID control, after you have calculated the tuning constant s.
MODEL TCL SECTION 1 1 CALIBRA TION - CONTROL concentration, temperature) compared to the measurement range, the dif ference between the 20 mA (Hi) and 4 (or 0) mA (Lo) setpoints, which you determined when configuring the analog output. In the example shown in Figure 1 1-1: The percent change in pH was: x 100% = = 33.
MODEL TCL SECTION 1 1 CALIBRA TION - CONTROL 1 1.2 TIME PROPORTIONAL CONTROL (TPC) MODE (Code -20) In the TPC mode, you must est ablish the following parameters which will determine how the Model 54eA controller responds to your system (see Section 7.

Det ail of Front Panel of 54eA Controller 12.2 TOT AL CHLORINE SENSOR 12.2.1 General When used in clean water , the total chlorine sensor requires little maintenance. Generally , the sensor needs maintenance when the response becomes slug- gish or noisy or when readings drift follow calibration.

MODEL TCL SECTION 13 TROUBLESHOOTING SECTION 13. TROUBLESHOOTING 13.1 OVERVIEW The Solu Comp II continuously monitors itself and the sensor for fault s. When the analyzer detects a fault, the word fault appears in the display alternately with the measurement.
68 MODEL TCL SECTION 13 TROUBLESHOOTING 13.3 TROUBLESHOOTING WHEN NO ERROR MESSAGE IS SHOWING 13.3.1 Zero current is too high A. Is the sensor properly wired to the analyzer? See Section 4.3. B. Is the zero solution chlorine free? T ake a sample of the zero solution and test it for total chlorine.
69 MODEL TCL SECTION 13 TROUBLESHOOTING 13.3.3 Sensitivity is low or readings are low A. Does the reagent carboy contain reagent? Is the reagent upt ake tubing below the level of the reagent? Has potassium iodide been added to the acetic acid (vinegar) reagent? B.
70 13.3.4 Process readings are erratic or wander A. Is the sensor properly wired to the analyzer? See Section 4.3. V erify that all connections are tight. B. Readings can be erratic when a new sensor is first placed in service. Readings usually stabilize aver about an hour .
71 MODEL TCL SECTION 13 TROUBLESHOOTING 13.3.6 Readings are too high A. Is the sample conditioning reagent clear and colorless? If the reagent is pale yellow , results will be high. The pale yellow color is caused by iodine, which comes from the reaction between atmospheric oxygen and pot as- sium iodide.
