METER PROGRAM The operating program of the meter has the following parts:
The TOU program;
The parameters relative to the maximum demands and load profile
The display sequences program
Miscellaneous parameters
The meter performs the energy measurement in 14 registers as follows:
Active imported energy
Active exported energy
Cumulated active energy
Reactive energies in I, II, III, IV quadrants
Cumulated reactive energies for the quadrants I+II, III+IV, I+III, II+IV,
Total reactive energy
Imported and exported apparent energy
Among these registers, up to eight of them can be chosen to be subject of the time
program in four tariffs in two different time sequences.
The meter calculates the maximum demand values for up to eight power registers
selected from the fourteen possible. These registers function in an ON-OFF regime after a
time program. For every power associated with a maximum demand register a threshold
value in percent from the maximum power of the meter. The maximum power is
calculated from the nominal value and the maximum current of the meter for every meter
variant.
The time program structure is as follows:
Seasons: Up to 12 time periods (seasons) of the year characterized by the beginning
day and month can be defined. For every season, the behavior for every day of
week (Monday…Sunday) is defined by allocating a day type to each of them.
Day types: Up to 24 day-types are possible to be defined, each of them being
characterized by the following features:
Two tariff-change sequences in up to four tariffs; in every sequence up to ten
switches can be defined, the time resolution for every switch being 30 minutes.
An ON-OFF switching sequence for every register from the four maximum demand
registers; in every sequence up to ten switches can be defined, the time resolution
for every switch being 30 minutes.
The operational program comprises also the selection of the energy registers associated
with TOU program and the selection of the power registers that will function after the
time schedule in the ON-OFF regime.
The Exclusion dates: Up to 64 special dates characterized by month, day and year
can be defined. These dates are exceptions from the TOU program as it is defined in the
corresponding season. For each special date the user can define the day type and the
number of days for this exception.
The Load profile and Maximum demand parameters:
6
Up to eight channels that will be stored in the load profile can be defined. The
channel selection is made from the 14 energy registers and the average voltage on the
three phases. The acquisition period in the load profile can be selected from the following
values string: 1,2,3,5,10,15,20,30,60 minutes.
The meter can four maximum demand registers corresponding for up to four
power types from the 14 types possible. The maximum demand calculus method can be
fixed interval type or sliding window type. The integration time can be selected from the
values string: 1,2,3,5,10,15,20,30,60 minutes. The user can set an inactive time for the
MD reset button of the meter and a forgiveness time for the MD calculus after a voltage
fault.
Display sequences:
The meter has two display sequences (1-normal, 2-alternate) the user can switch
between them using a button from the meter front plate.
Other parameters can be also programmed:
The daylight saving time rule: The change is made in every last Sunday of March
and October. The user can program the hour when the change will take place together
with sense of change. The daylight saving time change can be disabled.
The day for billing period; the user can program the day for billing period ending.
A new self-read will be made, with storing of energy registers and resetting the maximum
demand values.
The data set returned at the readout data operation as defined in IEC 1107. There
can be selected various combinations with the values of energy and maximum demand in
current billing period and the other periods. The reading of the events table can also be
programmed.
The events set that will be recorded in the events table; there can be selected from
the following event types: phase polarities, error in DSP circuit, battery, clock
programming, parameters programming, error in phase succession, reversing the energy
flow, network frequency out of range, the maximum demand value above defined
thresholds, the phase voltages out of range, and the voltage fault.
The display behavior regarding the warnings: the warnings will be ignored, added
on the end of the sequence or the display will freeze on warning
The display hold time for every displayed quantity.
The function accomplished for each of the three relays of the meter: none, the
maximum demand value above the programmed thresholds signaled out, the end of
integration period signaled out, the entering in one of the four tariffs in a certain sequence
is signaled out, the relay is used for pulse generation for active or active energy.
The communication baud rate as per IEC 1107;
The program ID;
The program has a certain syntax related to the programming lines, as shown in
the table below:

Besides the program proper, the current date and hour can also be programmed in
the meter. Other special commands are also available.
The program files, edited or read from the meter have pextn extension. Their
implicit location is <Folder Opticom2K>\ENERLUXTn Files\Program. Programs editing
and writing operations are made by means of a property sheet. Every time it is appealed
to for the creation of a new file, its contents will be of a self-created program file
type called “template.pextn”. Since this file is self-creating during the program
running, do not save your own programs in this file.

Operating program creation, editing, and writing
The operating program creation, editing and writing can be carried out by means of
PROGRAM property sheet.
The contents of the property sheet contain either template.pextn file, or the program file
loaded in the view zone of the main window of Opticom 2k program, if it exists.
The property sheet contains five property pages: Program summary, TOU program,
Max. demand and Load profile and Display sequences and Other parameters.
10
Program summary
This page enables program files loading and saving, current loaded program view, the
specification of target meter parameters (address and password) with reference to the
current meters list, the specification of what is required to be written into the meter, as
well as the communication process starting and control. The table shows the current
program contents loaded for editing and/or writing. Description column shows the
program line significance, Value column shows the program line according to syntax,
and Explanation column contains a concise explanation of the program line. The non-
defined program lines have NULL value.
Load button enables the loading of a program file other than the current one by means of
a standard box, Open. If the user has made modifications in the previously loaded file, a
warning will inform about the loss of the modifications that have been carried out.
Save button pressing saves the current file loaded by means of a standard box, Save As.
The user can navigate trough the table using the combo-box Go to section.
Meter group contains the combo box referring to the list of current meters, and General
option referring to a generic meter not included in the meters list. In case there is no
current list, only General option is present. Description combo-box contains the
description of all the meters from the meters list selected in Opticom 2k program. The
target meter selection is made from this running list. If All meters check box is selected,
the programming operation will be successively applied to all the meters on the list. If the
current list is null, the check box is disabled. This communication option shall be used
only when the meters are connected to a communication bus. Serial no and
Password editing fields reflect the contents of the current list concerning the meter series
(used as communication address) and password. For General option, these fields contain
11
General series and NULL password, or the one established in the reading dialogs
behaviour. The alteration of these fields is operative only during the existence of
PROGRAM property sheet, it not being contained in the meter list used by the program.
Communication section allows the communication operation starting and control.
The user may choose to enter write cumulated or separately for the following items:
TOU program
Exclusion dates
TOU Registers
MD Parameters
LP Parameters
Other parameters
Display sequence 1
Display sequence 2
Or he can choose the option Selection of single parameter if it is enabled. This option is
mutually exclusive to the other above options. The option is expressed by marking the
chosen check box. Before the programming process to start, the program detects if the
programming operation requires a previous erase of the stored data and warns the user, so
he can abort the operation. The user can make the option to create a new billing period
before programming by checking the option New billing period before program
providing that the register values will not be lost, excepting the load profile. When the
user reprograms the display sequences, he may choose to erase the old sequence by
checking the option Erase old display sequence. This can be useful when a long
sequence is replaced with a shorter one.
Pressing Start button starts the communication operation. The communication process
can be watched in WR (no. of transmitted characters) and RD (no. of read characters).
Pressing Stop button can stop the process. If an error happens to appear during the
communication process, the process ends and the user is warned by error message. The
properties page cannot be changed and PROGRAM property sheet cannot be closed
during the process.

19
METERS ACCESS Communication with the meters
The communication with the meters is based on IEC1107 module C protocol provisions.
The type of transmission is asynchronous, half duplex, with the following format of the
communication word: one start byte, 7 data bytes, even parity, one stop byte.
Communication starts with a foreword, initiated by the computer which comprises the
selection of the meter through its address, the meter type reading, and the negotiation of
the baud speed at which the communication will take place, and the type of
communication (data reading, program(s) reading). After this initial phase the reading or
writing operation is carried out.
The address of the meter is the specified one in the current list selected in Opticom 2k
program, and it has to correspond to the meter series + the last two digits of the
manufacturing year. The address is compulsory only for the meters connected to this
communication bus. In case of meters read through the optical port, the address is not
needed to be specified, the address used being General. On the other hand, the addresses
of Pxx cu xx=00…39 form are reserved to be used together with the parallel multiplexing
interface. They shall not be used if this interface is not present at the meter parallel port
that has been previously selected.
The meter proposes the communication speed, and it is the speed previously pre-
programmed in the meter. The program may ignore this proposal and forces another
communication speed.
Data reading requires only the knowledge of the communication protocol. An automatic
safety algorithm ensured by the program shall be fulfilled in program reading mode. The
programming mode requires the knowledge of the password previously entered into the
meter. If no password has been previously programmed, the chosen password shall be
void (equivalent with NULL password).
Certain reading or programming functions are available only when the meter is in the
CALIBRATING MODE. This mode operates only if a hardware modification is carried
out in the meter after it’s unsealing.
ENERLUXTn.mpl module accepts only ENERLUX Tn type meters. If another type
of device is accessed, even by observing IEC1107 requirements, error is signaled
out.
20
Reading dialogs behavior
The dialog box enables the configuration of the meter reading dialog boxes behaviour by
selecting or not Starts automatically and Close when communication ends options.
Default password editing field enables password configuration for “General” options, as
well for the quick programming. The option Warn before saving is related to the display
of the warning dialog boxes concerning the data erasing before the meter programming
operation. When importing load profile files from PSION terminals, the user can choose
for automatic generation of associated XML files. For data, report and load profile
readings the user can define new subfolders or reuse the existing ones.
Meters reading The meters reading functions refer to the following possibilities:
The data reading as the meter supplies them.
The reading of the meter work program as it has been previously programmed.
The reading of the meter status data: clock, display mode, working mode, and
current loop status.
The reading of a complete report of the contents of the meter memory which sums
up the values of all the previous reading types.
The result of the successful reading operations is the storage of the data read in
the files with names of the following type: MeterSerialNo@yymmddhhmmss and
extensions of dextn, pextn, sextn types, and rextn type, respectively (for program files
@yymmddhhmmss does not appear). After each successful reading operation, the
corresponding file will be automatically loaded in the view zone of Opticom 2K program.
The reading of the meter program and the meter status is carried out by using the safety
algorithm, while the data reading is possible only on the basis of the data reading
procedure, according to IEC1107 mode C.
21
All the reading operations are made by means of Read meter dialog box.
This dialog box is displayed after launching any of the reading command.
Exit button pressing, closes the dialog box.
Meter group contains the data of the current meters list, and also General option referring
to a generic meter not contained in the meters list. In case there is no current list, only
General option is present. Description combo box contains the descriptions of all the
meters from the meters list selected in Opticom 2K program. The selection of the target
meter is made from this running list. If All meters check box is selected, the
programming operation will be successively applied to all the meters on the list. If the
current list is null, the check box is disabled. This communication option shall be used
only when the meters are connected to a communication bus. Serial no editing field
reflects the contents of the current list according to the meter series (used as a
communication address). For general option, this contains General. The alteration of this
field is operative only during the presence of the dialog box, it not being comprised in the
list of the meters used by the program. If Start automatically check box is marked, the
communication process will start at the same time with the launching of the dialog box,
and if Close when communication ends check box is marked, the dialog box closes
automatically, in case there were no errors in the communication process. The status of
these boxes is memorized in dlgs.cfg file. The user can modify the status of these boxes
during the communication process.
Communication section enables the communication operation start and control. The
communication operation starts by pressing Start button. The communication process
can be watched in WR (no. of transmitted characters) field and RD (no. of read
characters) field. Pressing Stop button can interrupt the process. If an error appears
during the communication process, the process ends and the user is warned by an error
message. The dialog box cannot be closed during the communication process.
When the user reads data or reports, the Show Filters button is enabled. Pressing this
button will expand the dialog box, thus enabling the settings of certain filters related with
the amount of read data and the data displayed into the viewing area. The first list is
related with the amount of data delivered by the meter, while the other lists are related to
22
the displayed data. Using each of the four filter sets is activated by checking the
corresponding Use checkbox. A certain filter option become active when it requests
check mark next to it. Using the Select all options will establish the state for all options
of the corresponding filter. Various filter schemes can be defined and saved for further
use. The previous defined schemes appear in the Filter scheme combo-box.
The dialog box can be collapsed by pressing the Hide filters button.
Special readings
Special readings list comprises the types of special readings that may refer to
ENERLUXTn meter. The right side of the dialog box reflects the reading type selection
made by the user.
If Exit button is pressed, the dialog boxes close.
Meter group contains the data of the current meters list, as well as General option
referring to the generic meter that is not comprised in the meters list. If there is no current
list, only General option is present. Description combo-box contains the description of
all the meters from the meters list, selected in Opticom 2K program. The target meter is
selected from this combo box. If All meters check box is selected, all the meters on the
list will be programmed. If the current list is null, the check box is disabled. This
communication option shall be used only when the meters are connected to a
communication bus. Serial no and Password editing fields comprise the contents of the
current list, as far as the meter series (used as communication address) and password are
concerned. As concerns General option, these fields contain General series and NULL
password, or the one established in the reading dialogs behavior.
23
The alteration of these fields can be operated only if the dialog box is present, it not being
contained in the meters list used by the program. If Close when communication ends

Meter calibration
The meter calibration is made by writing several numeric coefficients in his internal non-
volatile memory. These coefficients are taking into account in numerical processing made
by the meter measuring circuit. The calibration means the finding of following
coefficients:
• Active power gain, divider factor for active energy meter constant and the scaling
values for the active energy registers of the measuring circuit.
• Reactive power gain, divider factor for reactive energy meter constant and the
scaling values for the active energy registers of the measuring circuit.
• The phase correction coefficient
• The offset for the active power
• The offset for the reactive power
• The gain, offset and scaling factor for RMS voltage
• The offset and scaling factor RMS current
• The gain and the scaling factor for the apparent energy registers.
These coefficients can be determined by comparing the target quantity that corresponds
to the coefficient to be determined with the value of the same quantity supplied by a
standard device. The new coefficient will be determined by applying some computation
formulas to the above-mentioned values and in some cases to the value of the coefficient
that is already present in the meter memory.
The preferred order for the whole calibration process is as follows:
Initializing the calibration
Active power gain calibration
Reactive power gain calibration
Phase calibration
Active power offset calibration (required only for meters with accuracy better
then 1% for active energy)
Reactive power offset calibration (required only for meters with accuracy better
then 1% for reactive energy)
RMS Voltage calibration
RMS Current calibration
40
Apparent energy gain calibration (the same values as for active energy can be
used)
Calibration adjusting (can be interfered between every two steps of the process)
