1. PREFACE 1.1 Introduction This Instruction Manual provides information for the installation and use of the FU24F SENCOM™ sensor. This digital sensor shows how Yokogawa applies the motto “Simply the Best” to sensor technology. Setup of the sensor is very easy because all sensor specific characteristics, such as calibration data, are stored in the sensor.
1.3 Warranty and Service Yokogawa products are guaranteed free from defects in workmanship and materials under normal use and service for a period of (typically) 12 months from the date of shipment from the manufacturer. Individual Sales organizations can deviate from the typical warranty period, and the conditions of sale relating to the original purchase order should be consulted.

Note: Sensor is suitable for pure water applications. 2.
2.8 Regulatory standards CE - ATEX - Certificate no. - Electrical data - Special - conditions (X) : Decision 768/2008/EC : Directive 94/9/EC, as amended by Regulation (EC) no. 1882/2003 : DEKRA 11ATEX0064 X II 1 G Ex ia IIC T3...T6 Ga : For sensor input circuits (by connector) connected to a certified intrinsically safe circuit with the following maximum values : Ui = 6.1 V; Ii = 230 mA; Pi = 1.
CSA Certificate no. Master contract no. : 2516979 : 182892 IS, Class I Div. 1, GP A, B, C, D T3…T6 Electrical data : For sensor input circuits (by connector), connected to a certified intrinsically safe circuit, with the following maximum values : Ui = 6.1 V; Ii = 230 mA; Pi = 1.2 W; Li = 4 μH; Ci = 30 μF or Certified intrinsically safe Yokogawa transmitter Model FLXA21 series. Ambient temperature : T6 for Tamb. -40 °C to +60 °C T5 for Tamb. -40 °C to +75 °C T4 for Tamb.
FM Certificate no. : 3046277 IS, Class I Div. 1, GP A, B, C, D T3…T6 Electrical data : For sensor input circuits (by connector), connected to a FM approved intrinsically safe apparatus meeting the entity parameters of the SENCOM™ sensor: Ui = 6.1 V; Ii = 230 mA; Pi = 1.2 W; Li = 4 μH; Ci = 30 μF or FM approved intrinsically safe Yokogawa transmitter Model FLXA21 series. Ambient temperature: T6 for Tamb. -40 °C to +60 °C T5 for Tamb. -40 °C to +75 °C T4 for Tamb. -40 °C to +85 °C T3 for Tamb.
Note: When the sensor has been connected to not intrinsically safe equipment which exceeds the restrictions regarding the sensor input circuit (see electrical data), the sensor is not suitable anymore for intrinsically safe use. 2.9 Shipping details Package size (L x W x H) : 300 x 100 x 75 mm (11.8 x 3.9 x 3.0 inch) Package weight : app. 0.33 kg (0.73 lbs) 2.

5. WIRING The FU24F is provided with a multipole M9 male connector for connection to the Yokogawa FLXA analyzer using the WU11 interconnection cable for SENCOM™ sensors. The connections of this M9 male connector (see Section 2.7 for details), the WU11 interconnection cable and the FLXA terminal strip are given in Table 3.
6.2 Calibration for ORP and rH measurement For calibration of ORP and rH, the procedure for MANUAL CALIBRATION can be used as described in the Instruction Manual of the FLXA analyzer. The rH value is a function of the reference system and the pH value of the buffer solution. The FU24F sensor has a reference system of saturated Silver/Silver Chloride (Ag/AgCl).
