Connecting vibration sensor

The sensor uses a standard Vutlan analog RJS5 RJ11 sensor cable for connecting to the monitoring unit.

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 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 a 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.

Analog sensor connection

This section includes child pages:

Connecting analog sensors

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.

If strong electromagnetic interference is present, we recommend using a 3-pair cable CAN FTP for sensor connection!

Extending the number of analog sensors

Using CAN extension "VT408 / Sensor extension unit" it is possible to increase the number of analog sensors connected to the monitoring unit up to 80 sensors.

Chain connection of analog sensors

This procedure applies to the following sensors, which are supported by the appliance and are connected to the analog ports:

VT530 and VT560 are the only analog sensors that allow non-addressable chain connection.  All the sensors in one chain are seen by the system as one sensor.  One chain can have up to 10 sensors. Example of such connection:

Sensor configuration

Adding logic schemes

Configuring the sensitivity of the sensor

The sensor is very sensitive. At times this may prove to be too sensitive. In this case, it is possible to lower the sensor's sensitivity:

1) Unplug the sensor from the cable.

2) Open the sensor cover using a flat screw.

3) Take the two-pin jumper header out. This will lower the sensitivity slightly.

4) Close the cover and plug the sensor back in.

If the sensitivity is still too high, Vutlan can produce a custom vibration sensor will a much lesser sensitivity on demand. In this case, please contact the sales team.

Sensor configuration

Contents

Settings tab

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:

Name

The name is given by the system automatically. You can change it to anything you want.

ID

System ID of the element.

Type

Examples: temperature, humidity, vibration.

Class

Examples: analog, CAN, switch, discrete.

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:

In the picture above, the "Current value" equals 41.0 and is represented by the small triangle. Currently, the triangle is green because it is situated in the "Normal" range. Hence the sensor says that the "Current state" is "Normal". This value is used by the system's "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 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 of the sensor has left the current range.
Each state has its field. Which determines the time that the sensor value must continuously hold for the state to change to the specified.

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's flash memory press "  "  then "OK" to confirm. 

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 a 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.

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)

"b" = the value that the sensor shows in WebUI when there's no current. Let's say that b = + 0.021

You should use the following formula for HAT: 100/5*(x-y)

The expression formula would be 20*(x-0.021)

Point is used as a decimal separator (3.14)

Charts tab

The charts tab shows the following:

  • last 100 seconds

  • last 100 minutes

  • last 100 hours

  • last 100 days


Refresh data

Export data

XML or CSV

Exporting data through WebUI does not work for more than a couple of days and is very rough. If you need detailed log data, use the logging of sensor values to the media.
Read more at System Log, Sensors dump files.

Note: Make sure no endpoint security services used in the network are not blocking the download of XML and CSV files.

Reset smoke sensors

If analog sensors like VT560 / Smoke detector/ sensor detects smoke or fire, it will go into “Alarm” mode. Alarm mode can only be switched off manually using the Reset smoke detectors panel or using the onboard sensor Analog sensor power reset is found in the “System tree” >> “Onboard”.
