Page 13: General Description
Together these compounds are referred to as Bound or Combined Chlorine. Total Chlorine is the sum of the Bound Chlorine and Free Chlorine in the sample, the TC80 measures Total Chlorine. The TC80 is a complete system for measuring Total Chlorine. The panel mounted system includes a Constant Head Flow Controller (CHFC), Total Chlorine sensor (TCS) and Flow Cell, pH sensor (S80pH) and Flow Cell and the T80 Transmitter. -

IRING ENSOR The Total Chlorine Sensor and the S80 pH Sensor were connected to the TC80 analyzer at the factory, no additional connections are necessary. Color coded connections for these sensors are shown in the wiring diagrams in Section 8.3 or on the inside cover of the T80 transmitter. -
Page 19: Installing The Sensors
2.3 INSTALLING SENSORS The TC80 is supplied with the sensor cables pre-wired to the analyzer. The TC80 instrument and sensors were calibrated at the factory and should be ready for use when assembled. However, changes may have occurred during shipping and storage requiring recalibration. (See Calibration section 4.2 below) The pH sensor mounts in the Flow Cell using an o-ring sealed flange/union mount with threaded locking cap. -

4.0.3 MANUAL C ALIBRATION DESCRIPTION Manual calibration allows the user to enter calibration data for an electrode into the transmitter without performing a calibration. A MANUAL Calibration requires the entry of three pieces of data, (1) A concentration Page 31 Model TC80... - Page 33 with the (2) corresponding mV and (3) a slope for the electrode. This allows laboratory generated calibration data for an electrode to be entered in a remote analyzer where calibration is difficult or impractical. The pictures show a Manual Calibration for a Total Chlorine sensor using the default values of 0.00 ppb = 0.00 mV and 8.0 nA/ppm.

Cal 2. Cal 2 sets the slope of the sensor. It is accomplished by setting the ppm value of the instrument to agree with a DPD tested value of the water flowing through the TC80 Analyzer. The analyzer will suggest a corrected value of 0.00 ppm, 5.00 ppm or 10.00 ppm, which will not be correct unless that happens to be the actual value... -

5.0 MAINTENANCE The Model T80 transmitter requires no periodic maintenance, except to make sure the front window is kept clean in order to permit a clear view of the display and allow proper operation of the navigation buttons. If the window becomes soiled, clean it using a soft damp cloth or soft tissue. -
Page 38: Ph Sensor
An important aspect of sensor maintenance is the service of the electrode cartridge. After being in operation, an electrode may begin to exhibit slow response or non-reproducible measurements. This may be due to coating of the measurement electrode or clogging of the reference junction. Regular electrode cleaning reduces problems Page 37 Model TC80... -
Page 39: Ph Electrode Cartridge Cleaning
If the electrode must be left out of the process for an extended period of time, store it in a solution of water saturated with KCl or a 4.0 pH buffer solution. ECD does not recommend the storage of electrodes in distilled or deionized water. -

- Page 53 Supply chlorinated water to the TC80 and allow the reading to stabilize for at least 2 hours. The analyzer should display some non-zero value, 1-3 ppm is a good range. When the reading has stabilized record the reading and start the chlorine feed by setting the pump speed to 50.
