Physical description VT407 / AC current converter

 

 

 

 

 

 

 


Function

Simple open-loop AC current transducer HAT-100Q1 can measure AC currents in the range of 0-100A. Data can be transferred to the monitoring system using AC converter VT407.

HAT-100Q1 and VT407 and purchased separately.

VT407 AC converter is an analog plug-and-play device. Can be connected to any analog port (A1...A8) of the Vutlan monitoring unit.

The maximum amount of connected VT407 converters and the maximum length from the monitoring unit can be extended using the VT408 / Sensor extension unit.

Components

The transducer HAT-100Q1 consists of a plastic housing with an open/closed AC current loop and 4 4-pin terminal connectors. The current converter VT407 is a simple plastic case with 4 pins input, DC 12V socket, and RJ output for connection to monitoring units.

Safety instructions

  • Please observe the valid regulations for installation in the country in which the current transducer is installed and operated and the national regulations for accident prevention. Please also observe any internal company regulations, such as work, operating, and safety regulations.

  • The technical specifications and limit values stated must not be exceeded under any circumstances. In particular, this applies to the specified ambient temperature range and IP protection category.

Siting location requirements

To ensure proper functionality, the conditions specified in the section “Technical specifications” must be observed.

Installation procedure

Notes on assembly

  • Be careful, the transducer's maximum isolation voltage is 2kV.

  • The transducer can measure AC current on any current wire, not more than 10 mm in diameter. Just open the cover, insert the wire, and close it.

  • Max. distance for the current converter from the monitoring unit is 50 meters.

Installation

The transducer and the converter are installed together.

  1. Mount HAT-100Q1 transducer using M4 screws and M4 nuts. The distance between mounting holes is 50 mm.  

  2. Mount VT407 current transceiver using M4 screws and M4 nuts or double-sided stickers. The distance between mounting holes is 60 mm.

  3. Connect both HAT-100Q1 and VT407 using a cable. The cable is included in the package of VT407. The cable has x4 conductors and x2 power connectors  (4P 5.08mm and 4P 3.81mm) at each end.

Connection

  • Connect the converter to the monitoring unit by RJ11 cable, connect the 12V power adapter connected to 230V, and connect a flat cable with green connectors to the transducer. 

  • Two green LEDs will be lit on a sensor. The monitoring system will automatically sense the current converter as a sensor.

The new sensor will appear in the web interface of the system. Click on the "System tree" menu and you will find a new sensor marked by an icon (abbreviation from Voltage function, used for sensor monitors and converters). Click on the sensor to open its properties.

A modal window with sensor properties will pop up.

  1. Change the type of the sensor by choosing "Current". Choosing any type of sensor does not affect sensor properties, it only changes the sensor icon for the comfort of usage.





  2. Change the name of the sensor, for example, "AC current".

  3. How to use an "Expression formula": 20 * (x-B).  "B" indicates the voltage at the output of the current transducer at zero current. 

  4. To measure "B", measure the readings of the monitoring system at zero current in the transducer. Typically B is about 0.017 - 0.021.

    Then you can write the formula "20*(x-B)". Push OK.

  5. Now the system is ready to measure the current in the transducer core.

  6. Finally put in the threshold levels by dragging: Low alarm, Low warning, High warning, High alarm levels.


    For example, the graph above shows that the state of the sensor at the moment is "Normal" because 20.4 is between "Low warning" and "High warning" states, which is considered a "normal" state.

  7. Click “Save” on a diskette at the bottom right of the “Properties” window. The page will reload and the sensor will update by changing its icon type to

    (abbreviation from "Ampers").

Manipulating transducers

Do not tweak the transducer's variable resistors. They are tweaked by the manufacturer for optimal measurement. Tweaking these may result in incorrect measurements.

Example 1: Equipment life prediction using a current sensor

 

Example 2: Equipment jam notification and sensing

 

Example 3: Switch off equipment before it overloads
