Description

Transmit measurements cyclically (x10s)

[0,1,2...17280]

The group objects with the below-mentioned
measured values of channel 1, 2 or 3 are
transmitted cyclically in temporal distance of the
parametrized values

Transmit current cyclically

[Yes / No]

It is set whether the measured value is
transmitted at the above-mentioned cycle time.

Transmit power factor cyclically

[Yes / No]

It is set whether the measured value is
transmitted at the above-mentioned cycle time.

Transmit THD-U cyclically

[Yes / No]

It is set whether the measured value is
transmitted at the above-mentioned cycle time.

Transmit THD-I cyclically

[Yes / No]

It is set whether the measured value is
transmitted at the above-mentioned cycle time.

Transmit spectrum U cyclically

[Yes / No]

It is set whether the measured value is
transmitted at the above-mentioned cycle time.

Transmit spectrum I cyclically

[Yes / No]

It is set whether the measured value is
transmitted at the above-mentioned cycle time.

Message at limit value (current)

[Yes / No]

When exceeding or falling below a threshold value
of the current on channel 1, 2 or 3 a group object
is transmitted. Release of the limit parameter and
the group object.

Limit value (x0.1%)

[0, 1, 2 ... 1000]

Limit value of the current on channel 1, 2 or 3,
which shall be monitored. The limit is given here
as a percentage of the reference current. See also
section Message of limit values.

Message at transient current peak

[Yes / No]

In case of an appearance of a transient current
spike with a peak value min. 140A a group object
is transmitted. If 140A is exceeded 1 is
transmitted. Release of the group object.
Transient currents (operations) are not predictable
(at random) and of a limited duration. They are not
repeated periodically and their shape can not be
clearly predict. Transient current spikes can be
caused e.g. by lightning strikes or switching a
large capacity or a large transformer (Inrush).

Message at limit value (THD-U)

[Yes / No]

In case of exceeding or falling below of a limit
value for THD-U on channel 1, 2 or 3, a group
object is transmitted. Release of the limit
parameter and the group object.

Limit value (x0.1%)

[0, 1, ... 255]

Limit value of THD-U on channel 1, 2 or 3.

Message at limit value (THD-I)

[Yes / No]

In case of exceeding or falling below of a limit
value for THD-I on channel 1, 2 or 3, a group
object is transmitted. Release of the limit
parameter and the group object.

Limit value(x0.1%)

[0, 1, ... 255]

Limit value of THD-I on channel 1, 2 or 3.
