T3...-73-M..
APPLICATION
The three-phase three-element active energy meter with programmable
electronic maximum demand indicator (MDI) is designed for
measurement and registration of electric energy and power to single
or double-tariff registers. It is used for direct connection or via measuring
transformers to three-phase four-wire system with balanced
and unbalanced load.
It is suitable for direct reading or reading with using multiplying factors.
All the data can be read-out visually, or automatically by means of
HHU-Hand Held Unit or PC with corresponding programme software.
RATINGS
The measuring and technical qualities of the meter T3.. comply with
the following International Electrotechnical Commission Publications
(EN 60 521, IEC 521) and Germany Standard (VDE 0418). The MDI
electro-technical qualities comply with IEC 211, IEC 1036. Their construction
and mechanical dimensions comply with DIN 43857 and all
respective DIN dimensional standards.
The accuracy class is 2. The meters connected via instrument transformers
can be also class 1.
GENERAL CHARACTERISTICS:
The meter is an electromechanical type, with incorporated electronic
microprocessor - based, programmable MDI. It is designed as simply
replaceable module which enables the access to testing and calibration
spots of induction measuring system. The meter measuring system
is provided with mechanical parts for fixing of MDI, a special version
of the rotor with markers for detection of revolutions, and voltage
electromagnets with additional winding for MDI power supply.
Basic functions of meter:
– measurement and registration of electric energy
– measurement and registration of max. average demand
– registration of previous maximums
– registration of cumulative maximums
– indication of function errors
Display – 12 digit LCD - with back light
Keyboard (Push-buttons)
– CALL key button (call-up sequence of the meter display)
– RESET key button (resetting of MDI into
initial position represents the end of
billing period)
Communication port
Optical port for meter reading, using
magnetically attached optical head.
Automatic read-out is performed in
compliance with IEC 1107 recommendation,
“Data exchange for meter-reading,
tariff and load control. Direct local
data exchange."
Data transmission is performed via
two-directional IR optical interface,
which corresponds to C mode. Protection
of total data block complies
with DIN 66219 standard.

DATA DISPLAY
Data on numerical 12-digit display
are displayed cyclically. A data
identification and data in register
are displayed on the LCD.
08 00002.6
Data in register
Data identification
Every ten seconds data, shown
in table 4.1., are displayed. The
display is not illuminated.
When a key (Call) for manual
data read-out is pressed, the
display is illuminated for 3 minutes.
Every ten seconds data
are displayed cyclically as
shown in table 1. When a key is
pressed the second time, data
stated in table 4.2. are displayed
then. If you want certain
data are to be shown, the CALL
key should be pressed successively
until desired data are displayed
on the LCD.
Previous monthly values are stated
for the case of 15 stored
billing periods. In the table RR-1
or RR-15 the data value under
the data identification 01 is
decreased for 1 or 15.
Programming:
The meter MDI module is programmable
and programming
method depends on the MDI
module equipment. With maximal
equipped plate the device can
be set manually or over IR optical
interface with HHU or PC
and with corresponding programme
software. Programmable
options are shown in table 4.2.
stated at D.I. 90 up to 95.
