Connecting vibration sensor
The sensor uses a standard Vutlan analog for connecting to the monitoring unit.RJS5 RJ11 sensor cable
Analog sensor connection
Analog sensors connection
Connect the analog sensor by a supplied RJ-11 (6P4C) cable to any analog port "A1 .. A8" or "Sensor" port. The determination
of the sensor type and connection will occur automatically.

6P4C RJ11 cable wiring / pinouts
1- Yellow, 2- Green, 3- Red, 4 - Black
Colors are true for this telephone cable. Both ends match the colors and pinouts (identical).
Please refer to the RJ connectors comparison table:
If strong electromagnetic interference is present, we recommend using 3-pair cable CAN FTP for sensor connection!

Daisy chain connection
Some of the analog sensors can be connected in a daisy chain. Please refer to the article "Chain connection of analog sensors".
Extending the number of analog sensors
Using CAN extension " " it is possible to increase the number of analog sensors connected to the VT408 / Sensor extension unit
monitoring unit up to 80 sensors.

Installation using a sticker and a bracket
Option 1.
There's a round bump at the bottom of the plastic enclosure of the sensor. It is used for fastening when the sensor is mounted
together with the on walls using a screw. In the current example, it is not needed. If you are planning to mount a device
differently, do not follow this step.
Cut the round bump using a knife so that the bottom of the plastic enclosure will be flat.

Option 2.
a) Stick the mounting sensor to the surface using the sticker.
or
b) Stick a sensor to the surface using a screw.
Option 3.
Mount the sensor to the surface using a mounting bracket. The mounting bracket and the sensor can be either attached by the
stickers or together with screws and nuts.

Connecting the sensor
Sensor configurations
To configure a sensor, go to "Main menu" >> "System tree" and click on the sensor element in the tree. A modal window with
sensor properties will pop up. Change the needed settings and click "OK" or "Apply" at the bottom of the "Properties" window.

All sensors include:
1 Name Name is given by the system automatically. You can change it to anything you want.
3 ID System ID of the element.
4 Type Example: temperature, humidity, vibration.
5 Class Examples: analog, CAN, switch, discrete.
6 Hardware port The external port number on the device panel to which the sensor is connected (if the sensor is
external).
All sensors have threshold controls:

On the picture above, "Current value" equals 41.0 and is represented by the small triangle. Currently the triangle is green
because it is situated in an "Normal" range. Hence the sensor says that "Current state" is "Normal". This value is used by the
system "Logic schemes" menu to notify the administrator or take action.
Hysteresis
Sensors have the option of setting the hysteresis state. Hysteresis can be a time, a value or it can be disabled.
If the hysteresis is set in a time, the sensor will transmit to a new state with a delay of the specified number of seconds in the
corresponding field. The time counting will begin from the moment when the measured value value of the sensor has left the
current range.
If you set the hysteresis by value, the sensor transition to a new state will occur when the measured value of the sensor exits
beyond the current range, adjusted for the specified hysteresis value.
You can calibrate the sensors. Use K and B coefficients. After the calibration, please, save the values in flash memory.
To save sensor properties in the device flash memory press " " then "OK" to confirm.

Tuning the sensor value
Sensor readings can be tunned by a linear formula "y = k * x - b"
Example VT407 + HAT-100Q1 / AC current converter:
Metered current for HAT: from 0 to 100A (This means that the range equals 100, ) k = 100
The output of VT407 is 0-5V (That means that the range is equal to 5)
" " = the value that the sensor shown in WebUI when there's no current. Let's say that b b = + 0.021
You should use the following formula for HAT: 100/5*(x-y)
The expression formula would be 20*(x-0.021)
Example: Using fuel tanks.
Each fuel tank has it's own formula for volume vs height. Please see this useful resource for finding out such a formula.
https://www.calculatorsoup.com/calculators/construction/tank.php
In this can, You need to use non-linear formula.

Example: Why do we need to use Hysteresis
Let’s say that we have a temperature sensor. Let’s say that we have set up threshold values.
We have set the value 25.5 °C to be a threshold value between Normal/Alarm states.
If the temperature drops just below 25.5 °C You will have a “Normal” state.
If the temperature goes just above 25.5 °C You will have a “Warning” state.
Sometimes the temperature may stay at 25.5 °C and jump up and down by 0.1-0.3 °C. In this case, You will get too
many notifications that the sensor is showing Warning or Normal state.
In this case, we need to use a Hysteresis.
If the type “time” is chosen, the system will wait for a specified time before the State of the sensor is declared.
If type “value” is used, unless the temperature drops by a larger amount than specified, the sensor state will not be
declared.
