9 1. OVERVIEW < 1. Overview > 1-1 Model ST401 is a compact sampling system which can be used with the ph converter system and the model non-reagent type free available chlorine analyzer. The measurement can be started after only simple installation because the ST401 is provided with a pressure-reducing valve and ball valve, and shipped with customer ordered devices. 1.1 System configuration There are three types of sampling system. With free available chlorine analyzer, with ph converter (with the ultrasonic cleaner according to order) and with both non-reagent type free available chlorine analyzer and ph converter. The model name and suffix codes are shown in Table 1.1. The outline is shown in item 1.2 to 1.4.

48 Piping < 3. INSTALLATION, PIPIN AND WIRIN > Pressure range of measuring water is from 100 to 750 kpa (1 to 7.5 kg/cm 2 ) and the flow rate is from 0.1 to 10 l/min. Measuring water pipe should be hard PVC and VP16 (22 mm O.D.). Drain pipe should be hard PVC and VP40 (48 mm O.D.). Use proper sized or other fittings which suit those pipe sizes. Refer to external dimension (Figure 3.1 to 3.32) for the piping. Drain pipe should be inclined, to prevent build up of deposits and blockage. Horizontal piping should be as short as possible and should have a slope. NOTE When the system is used for measurement in heavily contaminated water other than tap water and industrial water, the filter of the pressure reducing valve may be clogged early. In that case take measures to avoid contamination, e.g., changing the sampling point. 3.5 Wiring WARNIN Do not supply the electric power until the wiring is completed. Electric shock may cause serious injury or death (1) Power supply The converter unit should be directly wired if only the ph converter system or the free available chlorine analyzer is installed in the sampling system. Refer to Figure 3.33 to 3.41 for the wiring of each equipment. A terminal box is installed when there are two or more converters including ultrasonic cleaner, or when arrestor option is specified. The power supply of ph converter, ultrasonic cleaner, and free available chlorine converter is wired from this terminal box. Connect the power supply wiring to corresponding terminals of the terminal box, refer to Figure 3.33 to Figure The terminal screw is M4. Use suitable terminal. (2) Analog output and contact output Refer to the manuals of ph converter and free available chlorine converter for their analog output and contact output wiring. Connect each wiring to corresponding terminals of the terminal box, refer to Figure 3.33 to Figure 3.43.
