Safety instructions

• Please observe the valid regulations for installation in the country in which current meter 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.

...

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

Notes on assembly

• Be careful, transducers max. voltage for isolation is 2kV.
• The transducer can measure AC current on any current wire, not more then 6 mm in diameter. Just open the cover, insert the wire and close.
• Max. distance for AC Ampere meter  from monitoring unit is 50 meters.

The transducer and the transceiver installed together.

• Mount transducer using M4 screws and M4 nuts. Distance between mounting holes is 50 mm.  
• Mount current transceiver using M4 screws and M4 nuts. Distance between mounting holes is 60 mm.
• Use a 4-core flat cable and two green connectors supplied with the transceiver and the transducer to assemble the connecting cable.

...

• Each VT417 sensor has it's own expression formula printed on it's plastic cover. Use it to configure the sensor.

Installation

• Connect VT417 current transformer to "VT417 converter" 2P terminal.
• Insert the power cable inside VT417 current transformer and close it. Max. power cable diameter is 6mm.
• Connect one end of RJ11

...

• 6P4C cable to monitoring unit and the other end to

• RJ11 output of

...

• VT417 converter. The converter is powered by the system using RJ11 6P4C cable. The monitoring system will automatically sense current transducer as a sensor.

Configuration

Once connected the analog port of the monitoring system, the system will automatically sense VT417 as a sensor.

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

...

A modal window with sensor properties will pop up.

...

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

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

...

Ampere meter".

3. Use "Expression formula"

...

. Each sensor has it's own expression formula. It is printed on VT417 converter's top cover. Example below:

In this example the expression formula for the current sensor equals "4 * x"

4. Put in the threshold levels by dragging: Low alarm, Low warning, High warning, High alarm levels.
Image Modified
For example, 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 "Normal" state.

5. Click “Save” or “Apply” at the bottom of the “Properties” window. The page will reload and the sensor will update by changing it's icon type to Image Modified(abreviation from: "Ampers").
