Safety Instructions

Intended use

The econ sens+ energy consumption meter is intended solely for the measurement of electrical

parameters such as voltage, current, power, electrical energy, etc.. Installation and initial operation

may only be performed by electrically qualified persons.

Hazard warnings

The warnings denote the following:

Danger:

Means that there is an immediate risk to the health of the user if the appropriate safety

measures are not taken.

Warning:

Risk of potential damage to property or damage to the device if the appropriate safety

measures are not taken.

Information on disposal

The econ sens+ energy consumption meter contains a small lithium battery. Never dispose of used

batteries with normal household waste. They should be handed in at a collection point for used

batteries.

Warranty Terms

econ solutions GmbH assumes no liability and furnishes no warranty for any consequences of

improper use, in particular if the user and installation instructions have not been observed. The user

must ensure that the device is not operated outside the specified technical parameters.

In the event of changes or modifications to the device and of unauthorized repairs by the user, the

warranty becomes void.

Description

econ sens + is a compact, versatile energy consumption meter with a web interface and memory

function.

It measures the voltage and the current of the individual phases and the voltage between PE and the

neutral conductor.

When calculating the power, econ sens+ is able to differentiate between the generated and consumed

power. The energy consumption values calculated from the power data are displayed to the user via

the web interface and made available for any energy monitoring systems or similar that may be

connected via:

1. 2 x S0 pulse outputs to DIN EN 62053-31 (for consumed and generated active energy)

2. Modbus TCP

3. Modbus RTU (RS-485)

Allowed the detection of active, reactive and apparent power, current and voltage, each per line and

further readings on the Modbus interface (see Chapter Modbus).

The econ sens+ samples the input voltages and currents at 32 samples/signal period. To do this, it

tracks the frequency of the inputs and continuously updates its sampling rate accordingly. At the same

time, the econ sens+ resamples the input voltages at 1kHz. These samples give a picture of the

waveform. These waveforms are stored for several types of events.

The econ sens + has a size of 16MB memory to store values, logs and events. It holds power logs per

second for the last 2 days. It logs all measurements per minute for the last 39 days, per interval (10 or 15

Safety Instructions and Warranty Terms 3

Manual econ sens+ Version 1.40

minutes) for the last 13 months and per day for the last 10 years. No logging is performed if the time is not

valid.

Logs are stored after every interval. Average, minimum and maximum values are determined over the

interval. The interval is expressed in seconds and can be either 600s (10min) or 900s (15min).

Special features

For 2, 3, and 4-wire power systems with arbitrary load

Modbus TCP

2 x S0 pulse outputs for consumed and generated active energy or alternatively,

Modbus RTU (RS 485)

Acquisition of instantaneous values for U, I, P, Q and power factor per phase, together with

mean and cumulative values

Current range up to 3200 A / phase

No additional current transformer needed

Integrated web interface for configuration and fast and simple data acquisition

Quick installation, even during operation*

*Please note!

In order to log the current strength, it is not necessary to switch off the consumer load that is to be measured, as the Rogowski

coils can be opened and wrapped round the conductor. When connecting the voltage path, the relevant safety regulations for

work on electrical systems must be observed!

“Link” LED: Lights up when there is an active connection to the network

“Activity” LED: Lights up or flashes as soon as data is sent or received via the Ethernet port

Reset: Reset button to perform “Factory Reset”.

RS485 model

The RS485 model of the econ sens + differs in its external appearance only by the absence of the

lower right corner of the front panel (see Figure 4). All operating and display elements are identical to

those of S0 model.

Further details on the connections can be found in the “Technical Data” chapter; examples of

connections can be found in the “Installation Instructions”.

Installation Instructions

Mounting the device on the top hat rail

The econ sens + energy consumption meter was designed for mounting on a top hat rail. The device

is attached at an angle to the top hat rail with the upper retaining lug and locked into place with light

downward pressure (see Fig. 5).

The device is dismounted as shown in Fig. 6. Press the device downwards using light pressure and

then pivot it upwards.

Connecting the voltage path

Figure 3: Mounting the econ sens+

Figure 4: Dismounting the econ sens+

Installation of the econ sens + may only be performed by specially trained staff

(e.g qualified electricians).

Safety regulations for working with electrical power systems must be observed

under all circumstances!

Safety Instructions and Warranty Terms 7

Manual econ sens+ Version 1.40

The econ sens+ energy consumption meter can be used with various public power supplies:

3-phase four-wire power system (with neutral conductor)

3-phase three-wire power system (without neutral conductor)

Single-phase power system

Fig. 7 shows the integration of the econ sens + into a 3-phase 4-wire power system.

The phases L1, L2 and L3 of the voltage path must be protected by means of automatic circuit

breakers to prevent the system from being damaged in the event of a short circuit. A B6 (max. B10)

automatic circuit breaker is recommended. For safety reasons it is preferable to use a short-circuit-

proof conductor (NSGAFÖU) in front of the circuit breakers.
