econ sens3 – operating instructions Page 1 of 4 EN
The product described herein was developed with the aim of fulfilling the
purpose defined under "Area of application". A complete installation with this
instrument includes additional components, such as separating devices and
safety shut-down components. The manufacturer of a system or machine is
responsible for ensuring its correct overall function. econ solutions GmbH cannot
guarantee all characteristics of an overall installation or machine which has not
been designed by econ solutions GmbH.
Additionally, econ solutions GmbH does not assume any liability for
recommendations provided and/or implied by the following description. No new
guarantee, warranty or liabilities claims exceeding the general terms of delivery
can be derived.from the following description.
Notice: Further information is provided in the manual under http://www.econ-
sens.com.
The econ sens3 multifunctional measuring instrument is exclusively intended for
recording electrical values such as voltage, current, output, energy etc. in building
installations and/or in distributing systems. The instrument is capable of 1-, 2-, or
3-phase measurements and can be used in two-wire, three-wire or four-wire TN,
TT and IT networks.
Characteristics (partially optional):
Completely parametrizable and readable for each web interface
Recording of more than 28 measuring parameters (current, voltage, effective
power and reactive power, generated and consumed power, each per phase),
Recording the measuring values on accessible mirco SD card,
Harmonic measurement up to the 100th harmonic,
(PRO version), recording of network events according to EN50160, e.g. voltage
drops, frequency shifts, harmonics, flicker
4 multiple IO ports, configurable, digital input, 0 - 10 V input/output, 0 - 20 mA
input/output), 100Mbit Ethernet interface (TPC Modbus TCP), Modbus interface
(Modbus RTU).
Supply possible via 230 VAC or 24 VDC
The econ sens3 multifunctional measuring instrument is intended for the stationary
installation in the building installation, on TS35 top-hat rails in distributors and rail
distributors within closed rooms. Vertical installation position according to figure 1
on page 3
Before its assembly, the instrument is to be checked for possible
transportation damage.
Assembly of the instrument:
1.) Slide the instrument onto the top-hat rail with the upper retaining
collar
2.) Move the metal base bars downwards, against the spring force, by
means of a flat head screw driver.
3.) Move the instrument into a horizontal position.
4.) Let the instrument latch into the top-hat rail by releasing the metal
base bar.
Assembly of the coils:
Install the coils as displayed in figure 2 on page 3. Do not install or commission
coils with damaged insulation.
Before the installation, operation or maintenance of the instrument,
read this operating instruction and the related manual.
Danger!
Hazardous voltage!
Danger to life or risk of severe injury!
Before starting any work, interrupt the voltage supply to the system and
the instrument.
Caution
The safe functioning of the instrument can only be guaranteed with the
admissible components.
Notice:
Qualified staff
The term qualified staff in the sense of the safety-related notices in the user
documents refers to persons who are familiar with the installation, assembly,
commissioning and operation of the product and have the qualifications
necessary for their respective activities, e.g.
• Training or instruction and/or authorisation for operating and servicing
instruments / systems in accordance with the standards of safety technology
for electrical circuits and instruments.
• Training or instruction in accordance with the standards of safety technology
with respect to the care and use of suitable safety equipment.
• First aid training
Danger!
Danger of electric shock or burns
Any non-compliance with these instructions will lead to death,
bodily injury or significant material damage.
Wear the prescribed protective clothing. Observe the general set-up and
safety regulations for working on high-voltage systems (e.g. DIN, VDE) as
well as the applicable national or international regulations.
Only staff with the corresponding qualifications may implement installation
and maintenance work on this instrument.
Before installing the instrument, check it for possible damage. A damaged
instrument must neither be installed nor commissioned. Before carrying out
any installation, maintenance or assembly work, both the supply voltage as
well as the measuring voltage on the instrument are to be switched off, and
the voltage supply to the system in which the econ sens3 is installed is to be
interrupted.
Before connecting the instrument, it is to be ensured that the local network
conditions correspond to the information provided on the name plate.
Supply voltage: Secure the supply voltage
of the instrument with an approved 10A safety device, tripping characteristic
C, at all times.
Voltage measurement inputs: The instrument is to be secured by an
admissible 10A back-up fuse or an admissible 10 A circuit breaker.
Separator: A suitable separator is to be installed upstream in order to
disconnect the current and voltage supply to the instrument! The separator
is to be installed close to the instrument, must be easily accessible by the
user and be marked as separator for the instrument.
Current measurement inputs: Current measurement with the instrument is
only possible with the Rogowski coils included in the scope of delivery.
These must not be installed on blank copper busbars but on insulated
busbars or cables only.
Caution!
Avoid condensation.
Sudden temperature fluctuations can cause condensation.
Condensation can impair the function of the instrument.
Store the instrument at the installation site for at least 2 hours
before starting the assembly.
