CIRWATT B 400
Instruction Manual
configuration: power supply, current measurement, measurement system, etc.
Temperature range: - 25 °C to + 70 °C.
Minimum current.
Additional metrology marking.
CE marking.
2�10 - ENCLOSURE
The dimensions of the enclosure of the
CIRWATT
, as well as its anchor points, are in accordance with
the DIN 43859 and DIN 43857 standards.
2�11 - CONNECTIONS
Laser marking on the meter enclosure. Contains a figure showing the electrical connections. When
necessary, a brief installation manual is also included to facilitate the start-up process.
2�12 - AUXILIARY CONTACTS (DEPENDING ON VERSION)
The meter may have a series of auxiliary contacts with varying functions depending on the version.
2�12�1 - VERSION WITH TARIFF INDICATOR OUTPUT
The meter has a relay output (250 V and 5 A
~
) indicating the activation of the tariff that has been
programmed into it.
2�12�2 - VERSION WITH PULSE INPUT
The meter will have a maximum of 4
inputs for counting pulses from other devices, such as water and
gas meters. The minimum pulse width time that the meter can detect is 30ms, and the maximum rate
it can read is 8 pulses per second.
The inputs are self-powered at + 5V, with a maximum current of 8 mA per input. As a result, a voltage
must never be applied to the inputs; rather, it must be a potential-free contact.
2�12�3 - VERSION WITH LEAKAGE CURRENT MEASUREMENT
The meter will have an input for connecting an external transformer of the
Circutor
WN series
,
which
will allow reading the differential current (leakage) present in the installation.
2�12�4 - VERSION WITH OPTOCOUPLER OUTPUT
The meter has optocoupler outputs to emit pulses based on the energy recorded. The maximum voltage
that can be applied is 24 V DC.
