  • Page 3: Purpose

    This paper is destined for operating staff to get to know the construction, mode of functioning and servicing of the level monitoring device SAU M6. SAU M6 device is certificated. The certificate of conformance №03.009.0102. 1. PURPOSE 1.1. General information 1.1.1.

  • Page 4: Performance Specification

    2. PERFORMANCE SPECIFICATION Basic specifications of the SAU M6 device are given in the table 1. Table 1 Item Magnitude Operating supply voltage 220 VAC, frequency 50 Hz Operating voltage range +10%... 15% of operating supply voltage Power consumption 6 W max Number of level monitoring channels Level sensors supply voltage, not more than 10 VAC, frequency 50 Hz...

  • Page 5: Mode Of Functioning And Construction Of The Device

    3. MODE OF FUNCTIONING AND CONSTRUCTION OF THE DEVICE 3.1. Mode of functioning 3.1.1. The functional diagram of SAU M6 device is given in the pic. 1. The device consists of three level monitoring channels. Each of them operates the same functions and consists of the following main items: –...
  • Page 6 3.1.2. Conductive fluid probes are used in the device as the level sensors. Conductive fluid probes can be used for fluid level monitoring if the fluid is electroconductive. For example, acid and alkali solutions, molten metals, water and water salt solutions, milk, etc. The simplest construction conductive fluid probes are metal corrosion strong electrodes, sealed from each other.
  • Page 7 The rest electrodes are signal. They should be placed at appropriate levels and be connected to signal inputs 1, 2, 3 of the device (contacts “Level 1”, “Level 2”, “Level 3” at the connection diagram, app. A). When the reservoir fills up electrodes connects with the fluid. On account of that current lines between common and appropriate signal input close in.
  • Page 8 3.1.3. Level sensor’s signals entry to appropriate inputs and transforms to optimal for further processing electrical signals. 3.1.4. There are stepped commutators X2 (X3, X4) in every channel of the device. They are electroconductivity sensitivity regulating devices of level monitoring channels. So SAU M6 device can work with different fluid mediums.
  • Page 9 3.2. Construction of the device 3.2.1. The device’s case is made of plastic. The case is destined for fasten on the wall (H type). Dimensions of the device are given in app. B. 3.2.2. There are LED indicators on the front panel of the device (pic. 4): –...
  • Page 10 3.2.3. The device consists from two printed circuit boards, connected to each other. There are signal LED indicators in the one of printed circuit boards. There are level monitoring channel’s scheme items, electric power supply unit and commutators X2…X7, which are destined to set the sensitivity of the level monitoring channels and to change the mode of behavior of the output relay’s in the second printed circuit board.

    4. SAFETY MEASURES 4.1. SAU M6 device satisfies 0 protection range according to the all Union State Standard 12.2.007.0 75. 4.2. “The rules of exploitation user’s electrical installations”, “The rules of protection of labour using user’s electrical installations” and demands of the all Union State Standard 12.3.019 80 are obligatory to keep while using and servicing the device.
  • Page 12 CAUTION! Device’s connector block withstanding voltage is 300 VAC maximum and it should be taken into account when supply voltage and external equipment are connecting to the connector block. It’s inadmissible to connect to contacts 7…17 different branches of three phase circuit 380/220 VAC. 5.2.2.
  • Page 13 5.2.4.3. Set supply main noise filters in device’s supply lines. 5.2.4.4. Set spark filters in power facilities commutation lines. 5.3. Preparation for work 5.3.1. Prepare place to set the device according to dimensions given in app. B. 5.3.2. It is necessary to check the commutator’s bridges in X2…X7 commutators, to bring to conformity with characteristics of engineering process taking into account information given in tables 2 and 3 before setting up the device.
  • Page 14 Commutators X5, X6, X7 specify mode of output relay’s R1 (“Level1”), R2 (“Level2”), R3 (“Level3”) behaviour accordingly. Commutator’s jumpers should be set according table 3. Commutators arrangement in the device is given in pic. 5. Pic. 5...
