Index System

Examples
D000030110 d – E650 Series 3 (ZMD400AT/CT, ZFD400AT/CT) – User Manual
The information concerning which data are shown in the display is made
with an index system and is supported by the unit over the value field.
The 8-digit index field permits all currently known index systems such as
DIN, LG, VEOe, OBIS, etc.
The B:C.D.E.F structure applies to OBIS (Object Identification System):
B Defines the channel number, i.e. the number of the input of a metering
device having several inputs for the measurement of energy of the
same or different types (e.g. in data concentrators, registration units).
This enables data from different sources to be identified.
C Defines the abstract or physical data items related to the information
source concerned, e.g. active power, reactive power, apparent power,
cosφ, current or voltage.
D Defines types, or the result of the processing of physical quantities
according to various specific algorithms. The algorithms can deliver
energy and demand quantities as well as other physical quantities.
E Defines the further processing of measurement results to tariff regis-
ters, according to the tariff rates in use. For abstract data or for meas-
urement results for which tariffs are not relevant, this value group can
be used for further classification.
F Defines the storage of data according to different billing periods. Where
this is not relevant, this value group can be used for further classification.
To simplify reading of the index field, individual parts of the OBIS code can
be omitted. The abstract or physical data C and type of data D must be
shown. You can find further information in the E650 Functional Description,
D000030112.
1.8.0: 1 = Active energy import (all phases); 8 = Status; 0 = Total
0.9.1: Local time
Reference is made for examples to the following display list and the read-
out log (see section 5.7 "Data Readout").
Indication of presence of phase voltages.
If the rotating field corresponds to that given by the
parameterisation, symbols L1, L2 and L3 are continuously
lit. Otherwise they flash every second.
The symbol appears if the charge voltage of the battery
fitted is too low (provided the meter is parameterised as
"fitted with battery").
The following units are shown:
W, var, VA, k..., M..., ...h, V, A, h, Hz, m³
(var and VA only for combimeters)
Up to 8-digit indices are displayed, which define
the value in the value field.
Up to 8-digit values are displayed.
An arrow symbol is an additional status indication for tariff
rates, reset block, test mode, etc. The arrow points to a
status description on the face plate.
