DESCRIPTION

FCA3000 is a three-phase converter with DC outputs (current or voltage), which convert the value measured by a Rogowski coil into true RMS value.
FCA3000 has 3 inputs channels suitable for 3 transducers; the 4 outputs are dedicated one for each transducer, the fourth gives the sum of the 3 current values.
These outputs can be used with any kind of indicating device such as voltmeter, oscilloscope, data logger, SCADA systems, protection systems, metering equipments, etc.
FCA3000 can be used both with rigid and flexible transducers.

PRELIMINARY CHECKS

NOTE
At the opening the box, check that the instrument has not been damaged during transport.

If the instrument appears to be damaged, contact the aftersales service.
The box contains:

• the instrument
• the user’s manual

INSTALLATION

NOTE
The equipment complies with the 89/366/EEC, 73/23/EEC standards and following amendments. However, if not properly installed, it may generate a magnetic field and radio interference. This is why compliance with EMC standards on electromagnetic compatibility is essential.

ENVIRONMENTAL REQUIREMENTS
The environment in which the instrument is installed must satisfy the following features:

• No vibrations
• Indoor area
• Operating temperature between -10°C and +50°C Storage temperature between -25°C and +60°C
• Max humidity 75% (no condensation) altitude up to 2000m

NOTE
The instrument must not be exposed to sun rays.

MOUNTING
Fastening to DIN EN 50022 rail is provided for the instrument.
To mount it on the DIN rail, you simply need to use a screw driver as a lever on the plastic hook on the base of the instrument itself. This operation will allow to fi t the instrument on the DIN rail.

SAFETY MEASURES

DANGER!
This warning means that a voltage exceeding 1kV (even if for short periods) may be present on the terminals.

WARNING!
Electrical instrument connections must be carried out only by skilled technicians who are aware of the risks involved to the presence of voltage. Before connecting, check the following:

1. the conductor wires are not powered
2. the power supply corresponds to the values on the instrument label
3. the instrument has been installed in a vibration-free environment a suitable temperature (see section 5.1)
4. the terminals are no longer accessible after being connected
5. the wiring is carried out in accordance with the standards in force in the country where the instrument is to be installed
6. an isolator and an over-current device (e.g. fuse) are installed between the instrument power supply and the electrical system
7. the connections are made respecting the polarities
8. the connectors are fixed in such a way that they cannot be accidentally disconnected

CONNECTIONS

The instrument connections are carried out through the following connectors, as indicated in the picture:

Pict. 7.1 – Connections

• a 3-pin female connector (power supply)
• a 6-pin female connector (inputs)
• a 8-pin female connector (outputs)

WARNING!
Before making any connection, check if the instrument is switched OFF.

POWER SUPPLY
WARNING! Before connecting the power supply, check if it corresponds to the plated voltage value (80-260 VAC or 19-60VDC).
The instrument does not have a protection fuse on the power supply, therefore the installer must protect it with a current backer and an overcurrent protection device (315mA delayed fuse, T type).

ANALOG INPUTS
The analog inputs allow the connection of 100 mV/kA signal Rogowski coils with 3000A full scale. On request, the input value can be customized to allow the connection of rigid or flexible Rogowski coils with full scale different from 3000A. Each one of the 3 inputs has 2 terminals; the ground is common to all the outputs.

ANALOG OUTPUTS
Two different analog outputs types are available: on DC current (standard version), or on DC voltage (on request). Each one of the 4 inputs has 2 terminals; the ground is common to all the outputs (see picture 7.3).

WARNING!
In case of analog output on DC current, the maximum value of delivered voltage is 10V, therefore the load must never exceed 300 Ohm.

WARNING!
In case of analog output on DC voltage, the internal resistance is 500 Ohm, therefore the load must never be lower than 100 kOhm.

The maximum output value of 20mA (in case of analog output on DC current), and of 10 VDC (in case of analog output on DC voltage), on the SUM output, corresponds to the sum of the 3 clamps full scale (e.g.: 3000A clamps, SUM f.s.=9000A).
The instrument is calibrated for the declared accuracy; if a further full scale regulation is necessary, remove the instrument panel, using a screwdriver (see picture 7.2), and operate on the trimmer located inside the instrument (see picture 7.4, OUT 1, 2, 3, SUM).
