them externally.
2.5.4  SEALS
The cover and base socket of the meter are closed, making it impossible to open them or insert foreign
objects without breaking the enclosure. In addition, the energy meter has a series of mechanical fixing
elements that prevent the enclosure from being opened. It also has regulatory seals, both on the
energy meter cover and on the sealable keypad and the terminal cover.
2.5.5 - WIRE COVER
The energy meter has an opaque cover over the top of the terminal box, the screws and the connection
conductors. The dimensions of the terminal cover meet the requirements for single-phase energy
meters, in compliance with the DIN 43857 standard.
The bottom part is made for easy breakage and to partially let the wires out, protecting access to the
terminals.
The energy meter has a sensor that detects the opening and closing of the terminal cover.This detection
is always made, even if the energy meter has no power supply.
2.5.6 - TERMINAL BOX
Screws
The screws are mixed, allowing the use of PZ2 (Pozi drive no. 2) and flat head screwdrivers. The
fastening is done with two screws, which are designed not to strip during the various tightening and
loosening operations that can take place over the life of the meter.

CIRWATT B 101-102
Instruction Manual
2.13 - REAL-TIME CLOCK (depending on the model)
The meter has a real-time clock capable of keeping the date and time with a drift of less than 0.5
seconds/day, as specified in the UNE EN 61038 standard.
The clock maintains this accuracy whether it is powered from the mains or by its own battery.
2.14 - BATTERY
The meter has a battery that allows the clock to remain operational in real time. This battery is not
removable and is sized to supply power for 5 years without plugging in the meter. When the meter is
plugged in, the battery consumption is zero. The use of laser-sealed batteries minimises the amount
of self-discharge, which makes it possible to guarantee the battery for the 20 years of the meter's
useful life.
2.15 - OPTICAL COMMUNICATIONS PORT
Every version of the device has an optical serial communications port, as per the IEC 62056-21:2003
standard. The communications port is fully compatible with the optical ports approved by the leading
electricity companies.
On the surface of the cover there is a profile for properly attaching and placing the optical heads.
2.16 - RESET
There is a full reset mode that re-establishes the default factory parameters on the unit and sets the
records to zero, except for the total values of the 6 energy magnitudes (EN50470-1 Standard, section
5.10).
This function is executed locally and acts on an element inside the physical enclosure, generating
an event. All programmed parameters and stored data will be deleted. The following data will be
maintained: date and time, battery status, manufacturer-set parameters and distributor-set parameters
(passwords, 9600 baud serial communications port, 7E1 serial port configuration and automatic
seasonal change).
2.17 - TARIFFS
The energy meter can handle up to 4 tariffs.These tariffs can be configured for different seasons (usu-
ally winter/summer), tariff periods and types of day (working or holiday).
These configurations are set in the factory or by authorised staff.
2.17.1  SEASONS
A season is defined as each period of time in which a natural year can be divided and during which the
associated billing conditions are not modified.
A maximum of 2 seasons can be configured. Only 2 seasons are defined for the year and they are

15
Instruction Manual
CIRWATT B 101-102
established by the dates of daylight saving time, with no need for any further parameterisation, since
they are adjusted automatically every year. The automatic time change option can be disabled.
2.17.2  TARIFF PERIODS
A tariff period is an hourly block in which a specific tariff is applied. There will be a minimum of one
hourly block and a maximum of three hourly blocks. Each period is identified with a growing number,
starting at 1 on the lower part of the screen (T8).
2.17.3  TYPES OF DAYS
A type of day is defined as the set of tariff periods assigned to each of the 24 hours of a day.
Each type of day is identified with a number, starting at 1 and increasing by one for subsequent types.
There is only one type of day.
2.18 - CLOSE OF BILLING PERIOD
The energy meter stores the billing closures (or monthly summary) with the programmed date and
time, the absolute total values of the energy magnitudes measured by the energy meter (A+, A-, R1, R2,
R3, R4), including both total values by tariff periods, and those accumulated since the last closure until
the current closure, to be displayed (from the energy meter’s start-up in the case of the first closure).
In addition, the maximum average quarter-hour active power calculation will be stored from the last
closure (maximeter, corresponding to magnitude A+). The units will be expressed in Wh for active en-
ergy and Varh for reactive energy.
Each closure will have an associated date and time. The energy meter must keep a log of the last 12
closures. The energy meter automatically performs the billing closure at 00:00 hours on a determined
date, which will match the end of an hourly integration period.
2.19 - MAXIMETER
The maximum refers to the highest value of average active power demanded in a 15-minute period in
the time between two consecutive billing period closings.
The 15-minute periods will coincide with the integration periods of the 15-minute load curve; that is,
for each hour, they will start at minute 0, 15, 30 and 45, ending when the next period begins. The max-
imum values are expressed in absolute value in W.
2.20 - EVENTS
The dates of every setup change, battery replacement, time change, billing period closings, etc., are
recorded.
The meter is capable of storing up to 128 records . The data organisation within the file is rotational.
This means that once the memory is full, the new data will overwrite the older data (FIFO type). This
system ensures that the meter always has up-to-date information that corresponds to the latest data
obtained.

16
CIRWATT B 101-102
Instruction Manual
The following events are registered:
Start
Power supply error
Time change
Software Update
Parameter modification
Intruder detection Start
Intruder detection End
Neutral current alarm
2.21 - LOAD CURVE (OPTIONAL)
The energy meter can have an adjustable load curve (usually between 15 and 60 minutes), where the
measured energies are recorded. The default recording period is 60 minutes.
The energy meter records and stores 6 energy records (in the case of active and reactive energy meas-
urements) in the Wh or Varh absolute form for a total of 10,000 records.
Imported Active Energy (non-vectorial, only magnitude) +A.
Exported Active Energy (non-vectorial, only magnitude) –A (optional, depending on the version).
Quadrant I Reactive Energy R (QI) (optional, depending on the version).
Quadrant II Reactive Energy R (QII) (optional, depending on the version).
Quadrant III Reactive Energy R (QIII) (optional, depending on the version).
Quadrant IV Reactive Energy R (QIV) (optional, depending on the version).
Date/time.
The default recording period of the load curve is 60 minutes. The load curve has no information gaps.
Therefore, any periods with no measurements can be filled in with empty records.
2.22 - DAYLIGHT SAVING TIME
The meter– analyser automatically changes the official time. If the device is without power at the time
of the change, the change will take place when power is restored and the device is initialised.
The parameters that define this change have two different formats: one of them is generic, such that
the time is updated annually automatically; the other relies on the parameters included in the specific
message of the communications protocol. The formats are:
Enabled: Generic format independent of the year, with month, day, time, delay or pre-set time
change, as per the applicable law (last Sunday of March, and last Sunday of October)
Disabled: Format that specifies year, month, day, time, delay or time change.
The parameters for changing the official time, regardless of the format in which they are programmed,
are automatically updated at the beginning of the year, based on the generic format. If the message
specified in the communications protocol for updating the official time change is received, the format
will be modified as laid out in this message.

Instruction Manual
CIRWATT B 101-102
2.23 - SYNCHRONISM
The device must have an internal clock with a calendar to perform the billing closures, maximum value
calculations, preparation of load curves and event dating and alarms.
Basic features:
The Accuracy of the clock will have a maximum deviation of 0.5 s/day. The accuracy features of
the internal clock are defined in EN 62054-21.
The clock can be synchronised and the time can be set locally or remotely, but this must always
be done with the communications protocol.
The operating reserve will be over 2 years in the absence of voltage.
2.24 - SECURITY
2.24.1  COMMUNICATIONS
There are two communications modes:
Data reading. The energy can be read from the energy meter without the use of a password in IEC-
62056-21 Mode C.
Device parameter configuration. A password is used to read all the parameters and records. It is
also needed to synchronise the date-time and to program the energy meter.
2.24.2  TAMPER DETECTOR
The device will generate an event when the unit’s terminal cover is removed. The alarm can only be
deactivated via the communications protocol. The minimum time between two tamper events is 60

2.24.6. PARAMETERIZATION RESET
There is a full reset mode that re-establishes the default factory parameters on the unit and sets the
records to zero, except for the total values of the 6 energy magnitudes (EN50470-1 Standard, section
5.10).This function is executed locally and acts on an element inside the physical enclosure, generating
an event.
All programmed parameters and stored data will be deleted. The following data will be maintained:
date and time, battery status, manufacturer-set parameters and distributor-set parameters (pass-
words, 9600 baud serial communications port, 7E1 serial port configuration and automatic seasonal
change).

3  OPERATION OF THE METER
This section describes the performance of the device from a functional point of view; that is, it explains
how to manage all the information it provides, as well as how to configure the system's various fea-
tures.
3.1 - NAVIGATION AND DISPLAY MODES
The read button will be used to navigate through the different information screens. Navigating within
the same level is done by using short presses. To move to a lower level, use a long press. The device
will return to standby mode 60 seconds after the last button press.
3.1.1  STANDBY MODE
The device is in this mode by default, as long as the buttons are not pressed.
The purpose of the standby screens is to display information cyclically, without having to perform any
action on the meter. This type of navigation is exclusive to standby mode.
The Scroll line will alternate the information every 6 seconds. A short press of the read button will
freeze the display on the totalizer reading that is being shown at that moment.
Use short clicks to move manually through all the totalizer readings. On devices set up as a simple
active tariff, the standby screen will only show the active totalizer.
3.1.2  READ MODE
Activated with a long press of the read button. Navigation within the same level will be cyclical.
This mode uses a display-tree structure arranged into three levels, which are used to access the in-
formation.
The different information that can be shown on the display in Read Mode is accessed by either long or
short presses of the Read button.
3.2 - DEFINITION OF SCREENS
By short pulsations it will display the different defined screens. The screens that can be shown on the
scrolling display can be configured by the user. The maximum allowed parameters are 16 variables.
3.2.1. MENU LIST
Staying on the cyclical display and making a long keystroke (more than 2 seconds) on the meter but-
ton it will show the meter menu list. On that screen different values can be shown like instant values,
alarms, bill closure information, pulse LED selection, version and CRC.
