- Page 5 analyser The Turtle Tough model TT-ISE-CL2 uses a membrane covered amperometric sensor to. continuously monitor and control free or total residual chlorine without any reagents or moving parts. The difference between the two models is the type of sensor used and corresponding measurement it produces, free or total chlorine.
- Page 6 analyser NOTE: Using the sensor without mounting it in the supplied flow cell will lead to incorrect measurement results; it cannot simply be submerged in a pipe, basin, channel or tank. analyser If no chlorine is to be measured for over 24 hours the sensor must be disconnected from the analyser, the membrane cap emptied, rinsed and the sensor stored per instructions.

- Page 8 2 & 3-Electrode Free Chlorine Sensor Description The 2 or 3-electrode membrane-covered, amperometric sensors are used to measure the concentration of free chlorine in drinking and swimming pool water, industrial, process and cooling water. The following inorganic chlorinating agents can be measured with the sensor for free chlorine: chlorine gas (Cl2), electrolytically generated chlorine, sodium hypochlorite (NaOCl, chlorine bleach lye), calcium hypochlorite (Ca(OCl)2) or chlorinated lime (Ca(OCl)Cl).
- Page 9 As there must be an electrical connection between the counter electrode and the measurement medium, the measurement medium must have a minimum conductivity of approx. 10 µ S/cm. This means that the sensors are not suitable for use in highly-purified water, or similar. 2-Electrode Free Chlorine Sensor Description The sensor for free chlorine is a potentiostatic 2-electrode sensor with a micro porous, Hydrophobic (moisture repellent) PTFE membrane and special electrolyte.

- Page 16 The electrolyte will come out of the valve opening when the membrane cap is screwed on. Wear safety goggles and gloves. Wash off electrolyte (an aqueous solution of an alkali halide) under flowing water. NEVER SCREW THE MEMBRANE CAP ON OR OFF WITHOUT FIRST MOVING THE VENT SEAL AWAY FROM THE VENT HOLE.
- Page 17 To avoid forming bubbles do not shake the electrolyte. Make sure the vent hole is open. Tilt the electrolyte bottle as shown to minimize bubbles and fill the membrane cap up to the brim with electrolyte, if needed tap to eliminate bubbles.
- Page 18 After tightening the membrane cap, slide the vent seal up into the groove, so that it covers the vent hole. Rub around the vent seal to remove any bubbles or voids. If liquid leaks through the membrane, the membrane is faulty and you must use a new membrane cap.
- Page 19 Install the Sensor Insert the sensor into the flow cell with the wiring terminals facing you. Slide the union nut over the sensor and tighten onto the flow cell. Slide the cable gland nut and terminal cover over the sensor cable in the order shown.
- Page 20 Screw the terminal cover onto the sensor and then tighten the cable gland nut. The solution ground pin on the front of the flow cell is normally not needed, it may be used if you find a solution ground is necessary. ...
- Page 21 Cleaning the electrode finger (3,4) incorrectly may damage the sensor. Do not sand the brown coating on the combined counter and reference electrode (3). Do not touch or contaminate the electrode finger (3,4). Carry out the following steps exactly as they are described. ...
- Page 22 The service life of the electrolyte is 3 to 6 months. The service life of the membrane depends on the water quality. If the sensor still indicates values that are too low after the electrode finger tip has been cleaned, a new membrane cap must be used.

- Page 26 The sample must be taken at a point after the chlorine has been thoroughly mixed and has had time to react completely with the process water. A sample point that is too close to the chorine injection point will deliver a sample that is not mixed adequately or has not had sufficient time to complete the chemical reaction, thereby producing inaccurate readings.
- Page 27 The TT-ISE-CL2 chlorine analyser is shipped with two serial number labels found on the bottom right side of the enclosure, and on the inside of the enclosure door. The labels include the factory calibrated chlorine residual range. Should technical assistance be required, refer to the serial number to identify your system.
- Page 28 analyser Locate at approximate shoulder height for convenience. The TT-ISE-CL2 should be level from side to side and front to back. 1. Attach the four mounting feet to the rear of the electronics enclosure using the included 5/16"-18 x 1/2" flat head screws.

You will find that lightly tapping with your fingernail works the best. You will hear a beep when a selection is made. Touching the Menu button will display the main submenus available to configure the analyser.
- Page 38 Setting the operating range will automatically set the mA output of the disinfectant residual to match the operating range, set the high alarm to 90% of span, and low alarm to 10% of span. The alarms can later be configured as needed. The range must match the operating range of the sensor. To change the operating range you must purchase a sensor with a different operating range.
- Page 39 There are a total of (8) 1A dry contact form C relays each with LED indicator installed on the circuit board, only (3) are active in the standard configuration. Relay 1 is dedicated to the High disinfectant alarm, Relay 2 for the Low disinfectant alarm, and Relay 3 for the No Flow alarm. Upon a relay energizing its LED indicator will light.
- Page 40 The accuracy of the TT-ISE-CL2 can never be greater than the instrument it is being calibrated against. Accuracy is a function of the method used, inherent tolerances in the calibration instrument, the quality and freshness of reagents, and the care taken to perform the calibration.
- Page 41 A zero-point calibration is not required for the chlorine sensors included. If there is no chlorine present in the process medium, approximately zero is indicated. The zero point is independent of changes in the flow rate, conductivity, temperature and pH value. If needed, the zero point can be re-set electrically.
- Page 42 The settings screen allows you to adjust pump motor speed (on vinegar buffered systems only) as well as the screen brightness and audio volume. This screen also contains the serial number, the software version number, and display version number. These numbers are required for customer service and technical support.

Connect the sensor to the indicator/controller and wait for approx. 5 minutes. 4. Read the signal from the cell on the analyser or measure it with a digital multimeter. The measured value should be approx.
- Page 46 The TT-ISE-CL2 analyser is designed to operate continuously, 24 hours a day, 365 days a year. The system requires little routine maintenance other than changing the sensor electrolyte at prescribed intervals and mandated calibration checks. However, regular maintenance should be performed to ensure optimum performance and accuracy.
