If this equipment is used in a manner not specified by the manufacturer, the protection provided by it against hazards may be impaired. • Failure to follow the proper instructions may cause any one of the following situations to occur: Loss of life; personal injury; property damage; damage to this instrument; and warranty invalidation. • Ensure that you have received the correct model and options from your purchase order. Verify that this manual covers your model and options. If not, call 1-800-854-8257 or 949-757-8500 to request correct manual. • For clarification of instructions, contact your Rosemount representative. • Follow all warnings, cautions, and instructions marked on and supplied with the product. • Use only qualified personnel to install, operate, update, program and maintain the product. • Educate your personnel in the proper installation, operation, and maintenance of the product. • Install equipment as specified in the Installation section of this manual. Follow appropriate local and national codes. Only connect the product to electrical and pressure sources specified in this manual. • Use only factory documented components for repair. Tampering or unauthorized substitution of parts and procedures can affect the performance and cause unsafe operation of your process. • All equipment doors must be closed and protective covers must be in place unless qualified personnel are performing maintenance. • If this equipment is used in a manner not specified by the manufacturer, the protection provided by it against hazards may be impaired. MODEL Xmt-P SPECIFICATIONS SPECIFICATIONS - GENERAL Case: ABS. panel mount, polycarbonate (pipe/surface mount). Both versions are NEMA 4X/CSA 4 (IP65). Dimensions Panel (code -10): 6.10 x 6.10 x 3.72 in. (155 x 155 x 94.5 mm) Surface/Pipe (code -11): 6.23 x 6.23 x 3.23 in. (158 x 158 x 82 mm); see page 5 for dimensions of pipe mounting bracket. Conduit openings: Accepts PG13.5 or 1/2 in. conduit fittings Ambient Temperature: 32 to 122°F (0 to 50°C). Some degradation of display above 50°C. Storage Temperature: -4 to 158°F (-20 to 70°C) Relative Humidity: 10 to 90% (non-condensing) Weight/Shipping Weight: 2 lb/3 lb (1 kg/1.5 kg) Display: Two line, 16-character display. Character height: 4.8 mm; first line shows process variable (pH, ORP, conductivity, % concentration, oxygen, ozone, chlorine, or monochloramine), second line shows process temperature and output current. For pH/chlorine combination, pH may also be displayed. Fault and warning messages, when triggered, alternate with temperature and output readings. During calibration and programming, messages, prompts, and editable values appear on the two-line display. Temperature resolution: 0.1°C (.99.9°C); 1°C (.100°C) Hazardous Location Approval: For details, see specifications for the measurement of interest. RFI/EMI: EN-61326 Digital Communications: For details, see specifications for the measurement of interest. Power & Load Requirements: A power supply voltage of 9-32 Vdc at 13 mA is required. FUNCTIONAL SPECIFICATIONS pH Range: 0 to 14 ORP Range: -1400 to +1400mV Calibrations/standardization: The automatic buffer recognition uses stored buffer values and their temperature curves for the most common buffer standards available worldwide. The transmitter also performs a stabilization check on the sensor in each buffer. A manual two-point calibration is made by immersing the sensor in two different buffer solutions and entering the pH values. The microprocessor automatically calculates the slope which is used for self-diagnostics. An error message will be displayed if the pH sensor is faulty. This slope can be read on the display and/or manually adjusted if desired. An on-line one-point process standardization is accomplished by entering the pH or ORP value of a grab sample. Preamplifier Location: A preamplifier must be used to convert the high impedance pH electrode signal to a low impedance signal for transmitter use. The integral preamplifier of the Model Xmt-P may be used when the sensor to transmitter distance is less than 15 ft (4.5 m). Locate the preamplifier in the sensor or junction box for longer distances. Automatic Temperature Compensation: External 3 or 4 wire Pt 100 RTD or Pt 1000 RTD located in the sensor, compensates the pH reading for temp...
