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:
– level sensor;
– input;
– threshold device (TD) with signal LED;
– output relay (R).
Pic. 1

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. One of
electrodes is common for all monitoring channels. It should be placed in the reservoir so that the test
portion of it is always in the fluid in the all monitoring range (from the lower level to upper level inclusive).
This electrode should be connected to the contact “Common” of the device (pic. 2, a).
Note. If your reservoir is made of metal you can use it body as the common electrode (pic. 2, b).

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. The device fixes it as reaching one of given
levels.
CAUTION! Conductometric method of fluid level monitoring may be not effective if you use
suspension or emulsion instead of fluid because of particles sedimentation. It may result to sealing
sensors electrodes.

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)
ineverychannelofthedevice.Theyareelectroconductivity
sensitivityregulating devices of level monitoring channels.
So SAUM6 device can work with different fluid mediums.
3.1.5. Threshold devices are destined to fix when
the fluid level is as high as conductometric sondes (given
levels) and to signal by lighting up LEDs LEVEL. Apart from
that threshold devices generate signals for output relays
control.
3.1.6.Output relays are destined to control external
equipment. External equipment supports performance of
the level monitoring engineering process. Operation of
relay will happen if appropriate signal electrode contacts
with the fluid.
The mode of relay’s behaviour in every channel
may be changed by the user using commutators X5 (X6,
X7), pic. 1. It may be used for functionality enhancement
of the device. Depending on relay’s commutator output relay can become “on” or “off” when sensor’s
electrode contacts with the fluid.
The time history of output relay’s working when all relays become “off” if level sensor’s signal
comes is given in pic. 3.

6. SETTING UP THE DEVICE
6.1. Setting up the device is fluid level monitoring channels sensitivity adjustment. To set up the
device follow given directions.
6.2. Switch on power 220 VAC 50 Hz and make sure that LED POWER on the front panel of the
device lights up.
6.3. Fill the reservoir up gradually and check lighting up LEDs LEVEL 3, LEVEL 2 and LEVEL 1 on
the front panel of the device as soon as the fluid reaches appropriated electrodes.
If one or more LEDs didn’t light up while the reservoir is filling you should increase level
monitoring channel’s sensitivity.
To change channel sensitivity use commutators X2 (channel “Level 1”), X3 (channel “Level 2”)
or X4 (channel “Level 3”). Level’s sensitivity increases when sequence number of commutator’s
jumper’s position increases and it decreases when sequence number of commutator’s jumper’s
position decreases.
CAUTION! The device’s connector block is under tension 220 VAC 50 Hz which is dangerous
forhuman life. Changing commutator’s jumpers position is possible only when thedeviceis completely
currentless.
6.4. Make gradually emptying of the reservoir and check going out LEDs LEVEL 1, LEVEL 2 and
LEVEL 3 on the front panel of the device.
If one or more LEDs don’t go out while the reservoir is emptying you should decrease level
monitoring channel’s sensitivity according p. 6.3.
6.5. To check up sensitivity settings quality make reservoir full and empty again and check if
level sensors work well by LEDs LEVEL 1, LEVEL 2 and LEVEL 3.
After doing this work the device is ready to operation.
