General Information Figure 7: Boiler/Condensate Sensor 2.3 The Digital Gateway The Digital Gateway was developed to provide a means to use existing analog sensors with the new digital controllers. The gateway contains all the necessary software and hardware to interface with the controller and output a digital signal. 2.4 Theory of Operation The Contacting Conductivity Sensors are designed to accurately measure conductivity/resistivity/TDS/salinity from ultrapure water (0.
Section 3 Installation DANGER Only qualified personnel should conduct the tasks described in this section of the manual. The system can be used with any sc controller. Refer to the controller manual for installation instructions. The Contacting Conductivity sensor may be ordered with an internal or external digital gateway. If you received an external digital gateway, refer to 3.2 "Using the Digital Gateway" on page 12 for digital gateway connecting/wiring and mounting instructions. 3.

Installation 3.2.2 Mounting the Digital Gateway The digital gateway is supplied with a mounting clip for mounting to a wall or other flat surface. Use an appropriate fastener to secure it to the wall. After the sensor is wired to the digital gateway and the two halves are threaded together, place the mounting clip over the center of the digital gateway and squeeze the clip together to secure. See Figure 12: "Mounting the Digital Gateway". Figure 11: Digital Gateway Dimensions 34.29 mm (1.
Installation 3.3 Installing the Sensor in the Sample Stream Two compression-style installation schemes are available. For sensors with a 0.05 cell constant, use ½-in or ¾-in male NPT compression fittings made of Kynar (PVDF) or 316 stainless steel. For sensors with any other cell constant, use a ¾-in. male NPT compression fitting made of Kynar or 316 stainless steel. In all cases, the fitting enables the sensor to be insertion mounted, up to 102 mm (4 in.) deep, into a pipe tee or vessel.

Section 4 Operation 4.1 Using an sc Controller Before using the sensor in combination with an sc controller make yourself familiar with the operating mode of the controller. Refer to the controller user manual and learn how to use and navigate the menu functions. 4.2 Sensor Setup When a sensor is initially installed, the serial number of the sensor will be displayed as the sensor name. To change the sensor name refer to the following instructions: 1. Select the Main Menu. 2.
Operation 4.5 SENSOR SETUP Menu SELECT SENSOR (if more than one sensor is attached) CONFIGURE 18 EDIT_NAME Enter a 10-digit name in any combination of symbols and alpha or numeric characters. SELECT MEASURE Choose from Conductivity, Resistivity, TDS, or Salinity. Default: Conductivity MEAS UNITS Choose from the displayed units (dependent on the parameter selected in the Set Parameter menu) TEMP UNITS Select Celsius or Fahrenheit.
Operation 4.5 SENSOR SETUP Menu SELECT SENSOR (if more than one sensor is attached) DIAG/TEST PROBE INFO Display the probe device driver version number, software version number, or probe 12-digit serial number using this menu. SIGNALS Display the conductivity A/D counts or the temperature output in Ohms CAL DATA Display the CELL K: 1.
Operation 4.6.2 One Point Sample Calibration The wet calibration requires that the sensor be immersed into a properly prepared conductivity reference solution or if installed in the process sample, the process value must be determined by laboratory analysis or comparison reading. Remove the probe from the process and clean it. Obtain a sample solution with a known value and proceed as follows: 1. Select the Main Menu. 2. From the Main Menu, select SENSOR SETUP and confirm. 3.
Operation 4.6.3.1 Preparing Conductivity Reference Solutions Use Table 6: "Conductivity Reference Solutions" on page 21 to prepare a conductivity reference solution with a value between 200 and 100,000 µS/cm. The value prepared should be near the typical measured process value for best accuracy. Add the listed grams of pure, dried NaCl to one liter of high-purity, deionized, CO2-free water at 25 °C to obtain the stated conductivity.

Section 5 Maintenance DANGER Only qualified personnel should conduct the tasks described in this section of the manual. 5.1 Maintenance Schedule Maintenance Task 90 days Clean the sensor1 x Calibrate Sensor (if required by regulatory agency) 1 Annually Per the schedule mandated by your regulatory agency. Cleaning frequency is application dependent. More or less frequent cleaning will be appropriate in some applications. 5.
Maintenance 9. Calibrate the analyzer using the procedure in the analyzer instruction manual. If calibration cannot be attained, check the sensor using the procedure in the troubleshooting section.
Section 6 Troubleshooting 6.1 Error Codes When a sensor is experiencing an error condition, the sensor reading on the measurement screen will flash and all relays and analog outputs associated with this sensor will be held. The following conditions will cause the sensor reading to flash: • Sensor calibration • Relay timer washing cycle • Loss of communication Select the SENSOR STATUS menu and confirm. Select ERRORS and confirm to determine the cause of the error.
Troubleshooting 6.3 General Troubleshooting Problem Resolution Reading is unstable Clean and calibrate sensor 6.4 Checking Sensor Operation 6.4.1 Sensors without the Integral Junction Box Use the following troubleshooting steps for sensors without the integrated integral junction box (Model: D3422, D3433, D3444, and D3455). 1. Disconnect the sensor from the analyzer or junction box. 2. Clean the sensor using the procedure in 5.2 "Cleaning the Sensor" on page 23. 3.

Troubleshooting 6.4.3 Sensor Linearity Check 1. Obtain two standards, one close to the maximum for the range of interest (high standard) and another with a value half way between the high standard and 0 (mid-range standard). 2. Prepare 50 mL high and mid-range standards in 100 mL beakers and add 50 mL of deionized water to another 100 mL beaker. 3. Insert the sensor into the beaker containing deionized water.
