2 General description
Kamstrup 162M and 382M are a generation of directly connected electricity meters for the measurement and
registration of electrical energy. The meters are full-electronic without movable parts. Thus, energy registration is
not affected by shock and impact during transportation and mounting. Furthermore, measurements are correct,
no matter the physical mounting direction. Using shunt as measuring principle, it is possible to obtain a good
linearity, a very large dynamic area and immunity to magnetism and DC currents.
The easily readable display scrolls automatically between readings, or readings can be changed manually by the
consumer activating a push button. The required display readings as well as their order are configurable. In
addition to being read from the display, data can be collected via the optical output or from the module area by
means of a suitable communication module. The unique module area also permits external monitoring of tariffs,
pulse inputs and outputs, and configuration as well as connection of AMR and AMM modules.
From the factory, the meter can be configured to measure both imported and exported energy. The meters are
constructed with independent and galvanically separated measuring systems (the number of measuring systems
depends on the meter type). This ensures a correct measurement irrespective of how many and which
measurement systems are used. The energy registration is saved in the integral data logger, which ensures good
data history.
The meter construction makes it immune to magnetic influence, and the measuring accuracy will not be
influenced by magnetism.
It is possible to supply the meter with battery backup for the integrated RTC (Real Time Clock) used for tariff
control and time stamping of data and events.
The tariff control permits up to 8 tariffs. The tariffs can be managed by the internal clock (RTC) on the basis of
preprogrammed time tables. The tariff shifts can also be effected by summer time/standard time and holidays.
The meter is configurable and can be supplied from the factory with required functions. This ensures a minimum
of configuration during installation. Furthermore, the meter can be configured to verification mode, which
improves the resolutions of the energy indications, thereby reducing the duration of test and verification.
The meter is approved according to current electricity meter standards.
Kamstrup electricity meters are supported by a Kamstrup configuration tool called METERTOOL.
2.1 Terms
Integration period: The integration period is the length of time over which the power is averaged in order
to find e.g. the peak power. For instance, it can be 15 min.
Load profile logger: A logger that contains a series of energy values A+, A-, R+, R- depending on meter type.
The interval between each values is defined by the integration period. As default the
logger contains the last 4 months of data.
Debiting period: The debiting period is a configurable length of time between each debiting entries
where the value of a number of predefined meter regsiters are logged. Usually the
debiting period is 1 month.
Debiting logger: Contains a series of predefined meter registers that are logged with a customer-
specific time interval defined as the debiting period. The depth of the logger is 36
entries.

2.2 Construction
The meter is designed as a three-piece plastic construction, consisting of housing, verification and meter covers,
all parts made of fire resistant plastic. The verification cover protects the metrological functions. It is not possible
to open the verification cover without breaking the metrological seal.
The meter cover covers the module area. Various communication modules, input/output and control modules can
be connected without reverification. Furthermore, the meter cover can be ordered with different lenghts. A short
version allows premounted terminal-pins or wires to be mounted, while longer version covers the terminal in- and
outputs
2.2.1 Terminals
The current terminal is a combined terminal and shunt. The terminal is the elevating type with one screw per
terminal, which secures quick and simple mounting. The construction and design of the terminal protect the
connected cable from being damaged during tightening. Furthermore, a good contact area is provided, which
minimises the contact resistance and thereby heating at heavy currents.
2.2.2 Measurement Construction
The meter is provided with 1 shunt per system for current mesurement, and it measures the voltage through a
voltage divider. A switch mode supply feeds measuring circuits and main processor with voltage. Furthermore, the
switch mode supply in combination with varistors and power resistors functions as an excellent transcient
protection.
The use of shunt and switch mode supply also makes sure that the meter is immune to magnetic influence.
Magnetic influence will be detected by the integral sensors and be registered in the meter’s event logger.
Using shunt as measuring principle for the current measurement where a resistance stable metal provokes a
given drop of voltage at a given current, makes the energy measurement secure and reliable. Another important
advantage of the measuring principle shunt is a linear change of the voltage drop, which is an expression of the
current consumption.
The meters are constructed with independent and galvanically separated measuring systems (the number of
measuring systems depends on the meter type). This ensures a correct measurement irrespective of how many
and which measurement systems are used.
The meter’s main processor with corresponding data logger has its own supply, which means that data is well
secured against transients.
Like voltage drop, energy consumption is calculated as an expression of the current compared to the phase
voltage and time. The energy registration per measuring system is communicated to the meter’s legal processor
via the meter’s internal bus system. After correction, the energies are summed in the main energy register.
Measured and calculated data is safely stored in the memory (EEPROM) and can be read out either via the module
area’s unique interface, or through the optical interface by means of an optical head.

2.3 Meter types
Kamstrup’s direct meters are available in different variants depending on the application for which they are used.
As default, in addition to many other functions, the meters are provided with debiting logger, event loggers,
voltage quality measurement, tamper detection, and the possibility of using up to 8 tariffs. Furthermore, the
meters can be supplied from the factory with internal disconnect function for disconnection and connection of the
consumer’s supply, configured for the measurement of energy types in all 4 quadrants, with integrated radio
transceiver, load profile logger, prepayment function, APS and smart disconnect.
The summary below provides an overview of which functions the meter types include.
The meter's type number consists of 13 characters that describe the meter's hardware and mechanics:
684-XXX-XX-XX-XXX for the 3-phase meter and 686-XXX-XX-XX-XXX for the 1-phase meter.

Furthermore, the above energy types are registered in tariffed registers T1, T2, T3, T4, T5, T6, T7 and T8.
For further information about tariff control, see section 3.4.
In addition, bidirectional positive registration in a register, i.e. active energy for import and export added
numerically, can be selected as a special register (control register). This register sums the energy positively
without considering whether the input and output terminals per system have been interchanged.
A1423 Numeric register for |A+| + |A-|. The value is displayed in kWh.
3.2.2 Energy calculation
There are several acceptable methods for calculating the energy in three-phase meters.
Three identical meters can obtain several different results for energy measurement dependent on the calculation
method.
If energy is imported on phases L1 and L2, and energy is exported on phase L3 as shown in Figure 2, the
calculation can be made according to the methods described below.

Figure 2: Example of energy consumption in a three-phase meter.
Figure 3 graphically shows the calculation of the total energy dependent on the applied calculation method. The
first method applies vector summation, which is known from the Ferraris meters where the energy is added in
consideration of sign. In the next example import and export are added individually, and finally is shown the
calculation with total summation where all contributions are added numerically is shown.

Vector summation Individually import/export Total summation
Figure 3: The three different calculation methods.
When using vector summation, the positive contributions are added and the negative contributions are
substracted in the same way as by electromechanical meters. Contributions from e.g. solar energy installations
will be set off in the total energy calculation. This calculation method is sensitive to incorrect installation and
manipulation.
Individually import/export calculation method has one register for the positive contributions and one for the
negative contributions.
Kamstrups 162M and 382M supports the individually import/export calculation method.
Note!
Total summation adds all contributions to the positive register whether one or all are negative. Kamstrup
Generation M meters doesn’t support this calculation method for the main energy registration, but have a
additional register for this called “A1423”.
3.2.3 Verification registers
For test purposes, the 4 main energy registers (A+, A-, R+, R-) can be displayed with higher resolution in format 3.4
(000.0000).
For test purpose it is possible to activate test mode. Test mode change the display setup to allow selection of
energy registers A+, A-, R+ and R- depending on the meter by activating the left push button. In test mode, the LED
blinks proportionally to the chosen energy type.
The meter changes automatically from test mode to normal mode 16 hours after the latest activation of the push
button, or if the meter is reset. METERTOOL can also be used for changing back to normal mode.
Finally, 6 seconds activation of the left push button can provoke a change to normal mode.
3.2.4 Resettable counter registers
The consumer can use a specific register (resettable counter) for monitoring the consumption in a given period,
e.g. every day or weekly.
In addition, the consumer can use another register (resettable counter) for monitoring the electricity production
that the consumer has delivered to the electricity grid, e.g. from a solar cell installation.
The resettable counters count with the same resolution as the main energy registers of the meter, but can be reset
by activating the push button for 6 seconds at the same time as the resettable counter reading is displayed.
No register values in the meter will decrease due to inverse current
flow, no matter of meter configuration.

3.2.5 Power registers
The meter registers the current power (instantaneous power) in all four qudrants. Registration of active and
reactive Power in the meter use same individually Import/export calculation method as in the case of energy
measurements.
Actual power
Actual power shows the current three-phase power consumption. The actual power can be shown in the display
and is calculated and updated every second.
Peak Power
The peak power is the highest averagely determined power registered during the debiting period. The averagely
determined power is based on a period that corresponds to the integration period. The peak power is available for
P+
max
, P-
max
, Q+
max
and Q-
max
.
Furthermore, the meter can be configured to register the peak power P+
max
for T1 and T2. Thus, the biggest positive
active power during the debiting period is found for T1 and T2, respectively.
At the end of the debiting period, the peak power and the accumulated peak power are stored and a new period
starts. The accumulated peak power accumulates the values of each period and the accumulated peak power of
the previous period. The peak power, however, is reset after each period.
Below the power registers are described:
P+ Active positive instantaneous power of quadrants 1 and 4. The power is displayed in kW in format
4.3 (0000.000).
P- Active negative instantaneous power of quadrants 2 and 3. The power is displayed in kW in format
4.3 (0000.000).
Q+ Reactive positive instantaneous power of quadrants 1 and 2. The power is displayed in kvar in
format 4.3 (0000.000).
Q- Reactive negative instantaneous power of quadrants 3 and 4. The power is displayed in kvar in
format 4.3 (0000.000).
P+
max
Maximum active positive power during the debiting period measured over an integration period
deriving from quadrants 1 and 4. The power is displayed in kW in format 4.3 (0000.000).
P-
max
Maximum active negative power during the present debiting period measured over an integration
period deriving from quadrants 2 and 3. The power is displayed in kW in format 4.3 (0000.000).
Q+
max
Maximum reactive positive power during the present debiting period measured over an integration
period deriving from quadrants 1 and 2. The power is displayed in kvar in format 4.3 (0000.000).
Q-
max
Maximum reactive negative power during the present debiting period measured over an integration
period deriving from quadrants 3 and 4. The power is displayed in kvar in format 4.3 (0000.000).
P+
max akk
Accumulated maximum active positive power during the present debiting period. To calculate the
accumulated peak power, the peak power of the present debiting period is added to the
accumulated peak power of the last debiting period.
P+
max, daily
Max active power within the 24 hours in question.
P+
min, daily
Min. active power within the 24 hours in question.
Available power registers depend on the chosen energy type. E.g. a two-qudrant meter (A+, A-) only contains P+
and P- power registers.
Power threshold value
It is possible to let a counter register how many times a power threshold value is exceeded. The value only
applies to active positive power P+.
The threshold value can be configured between 0 and 99 kW. If the limit is exceeded within the integration period
(5, 15, 30 or 60 min.), the counting is made in the power threshold counter.
The power threshold counter is registered in the debiting logger of the meter, and is reset at every debiting stop.

3.3 Time management
The meter has an internal real-time clock (RTC) with either battery or rechargeable backup unit (supercap).
3.3.1 Real-time clock (RTC)
The real-time clock (RTC) makes it possible to provide measured data with an accurate time stamp (typically
5ppm at 23C).
The real-time clock time stamps load profile and event values, changes tariff etc. In addition to the tariffs, it is
associated with a calendar.

The time is adjustable via the configuration program METERTOOL for kWh meter or via reading system. It is
possible to use daylight saving time with corresponding preprogramming of shifting dates, see more in section
10.2.4.
3.3.2 Backup
The meters can be supplied with either a non-rechargeable unit (battery) or a rechargeable type (supercap). The
backup time of the battery depends on the period of time the meter is without mains supply, and in addition, the
battery gives access to further functions such as display views despite lack of mains supply, see section 4.10 for
further information.
The lifetime of the backup unit also depends on the mains voltage supply to the meter and the ambient
temperature. For specifications, see also section 8.2.
3.3.3 Hour counter
As the RTC manage the date and time in the meter, an hour counter register manage the number of operating
hours of the meter, i.e. number of hours where main voltage are supplied to the meter.
3.4 Tariffs
The meter allows registration in eight tariffs for each energy type depending on configuration, see section 3.2.1.
The tariffs are active when at least one tariff-register has been selected in the display set-up. Do not forget to
select control type when activating tariffs.
The tariffs can be controlled in three different ways:
- Via communication commands, e.g. from a module or via METERTOOL, or
- Through the module’s I/O, or
- Internally by means of time control via the RTC.
Module I/O controlled tariffs use the ports of the module connector for changing the tariffs, e.g. if a tariff control
module prepared for 230 VAC is connected to 230 VAC. The inverted function can also be selected.

Table 2: 230VAC - tariff control.
The tariff reading is updated in the display every 10 secs. The active tariff is displayed by readings T1..T8.
The time-controlled tariff is possible using the RTC to control the tariffs on the basis of a preprogrammed shifting
table.
The set-up of the meter’s configuration makes conflicts between control methods impossible as the choice of one
method automatically excludes the others.
3.5 Voltage quality measurement
The meter makes it possible to register/measure the voltage quality.
The voltage quality measurement consists of voltage measurement, registration of maximum and minimum
voltage, overvoltage and undervoltage as well as voltage failures. All registrations take place per phase.

5512-1040 GB/05.2012/Rev. C1

3.5.1 Voltage measurement
The RMS voltage measured per phase with average determination every second forms the basis of the registration
of overvoltage, undervoltage, and voltage failures. The voltage per phase can be displayed with an accuracy
corresponding to the meter’s class.
3.5.2 Registration of overvoltage/undervoltage
Registration of overvoltage/undervoltage for diagnosing the voltage situation of the individual consumer is an
important tool in connection with the evaluation of possible complaints from consumers as well as network
analysis.
If one or more phases has/have been outside a configurable overvoltage (U
High
) or undervoltage (U
Low
) limit for
some time (t
d
), this is registered in the meter's event logger for voltage quality. The registration includes date and
hour. The time period which triggers a registration can be configured between 10 secs. and 2550 secs.
The limits for registration of overvoltage and undervoltage are configurable from 0 to 20 %, i.e. from 230 VAC – 20
% (184 VAC) to 230 VAC + 20 % (276 VAC).

3.5.3 Registration of voltage failures
Voltage failures on one or more phases lasting longer than the configurable time periode (t
d
) are registered in the
event logger with time stamps at voltage dropout (t
3
) and voltage recovery (t4) in Figure 6.
The time for the event is registered with date and hour.
The time for how long a voltage failure should last before it is registered in the voltage quality logger can be
configured in steps of 10 secs. The range is between 0 and 2550 seconds.
3.5.4 Time stamp with RTC
The time registration is made both at the the apperance of the voltage failure and at the return of voltage. An
example of this registration can be see in Figure 7, showing a read out from METERTOOL.
Figure 7: Logger registration of a voltage failure and re-power with correspondng log IDs and time stamps.
3.6 Loggers
The meter has several different loggers for registration of data and events, among others a debiting logger and
different loggers that secure the registration of events – as to internal errors, magnetic influence, access
registration (Tamper), clock, and voltage failure, load profile logger, andan analysis logger. The load profile and
analysis loggers share the same logging depth, which means that the depth of the analysis logger depends on the
logging depth of the load profile logger and thus the configuration of the meter.
3.6.1 Debiting logger
The debiting logger stores relevant data for a given period. The end of a debiting period is called debiting stop. A
debiting stop can be triggered by the meter’s internal clock or via a communication command.
With its logging depth of 36 loggings, the debiting logger makes it possible to store data for many purposes, e.g.
as a monthly logger controlled by either an internal RTC or an external unit. In the standard version, the loggings
are initiated by the meter’s time. The time for debiting stop has many options, e.g. monthly, every other month,
every six months or yearly.
The debiting logger stores the following values at debiting stop depending on the meter’s configuration:

Table 4: Registers stored in debiting logger 2.
The log interval can be configured to one day, one week or one month via METERTOOL. The logging depth is 45
loggings.
The log interval is Kamstrup factory standard which is one day.
3.6.3 Load profile logger
Kamstrup’s directly connected meters have an internal load profile logger that registers the energy with a
configurable interval, with the possibility of readouts, if required.
The meter enables the read-out of energy values in the load profile logger as both absolute and relative (delta)
values. Every data set includes log ID, RTC/Quality stamp and up to four energy registers.
The log ID is the meter’s identification of the data set and is only used in connection with readout. The RTC time
stamp indicates time of logging data in date and hour together with validation information. The number of register
values depends on the meter’s configuration of energy types.
The number of energy registers for which the meter is configured determines the number of registers for which the
load profile is logged.
The RTC/Quality stamp includes time, date and a data quality info, that validates each registration of eventually
time adjustments and/or voltage quality events, i.e. over and under voltages and voltage interrupts.
Readout can take place by means of the open standard DLMS or Kamstrup's own protocol KMP. The data format at
readout depends on whether absolute values or relative values are read out. The format of absolute values
follows the format in which data is registered (7.2), whereas the format of the relative values is [3.2] (XXX.XX)
kWh.

The registration interval follows the integration period, and the integration period can be changed after the
commissioning.
IMPORTANT: If the integration period is changed, the load profile logger is deleted.

3.6.4 Analysis logger
The analysis logger allows the client to configure the registers to log and the log interval. Up to 16 simultaneous
registers can be chosen. The log interval can be configured to 5, 15, 30 or 60 min. or 1 day. The logging depth of
the analysis logger varies from 7 days to approx. 520 days, depending on the number of registers, which registers
to log and the chosen log interval. Table 6 shows the registers that can be chosen for the analysis logger.

Table 7: Default setup for analysis logger.
Average phase voltage and phase current are calculated as the mean value during the integration period
configured for the analysis logger.
Phase currents are show as abolute values, i.e. with no sign to indicate the direction of the current.
3.6.5 Event logger for status
The status logger registers internal errors and can thus be used as an analytical tool to show the meter’s
condition.
The RAM is tested during start-up writing and reading, and both EEPROM and ROM are tested by checksum
calculation. Internal errors are indicated by a warning triangle in the display and cannot be reset without the
meter being returned to Kamstrup A/S.
The status logger registers with time stamp whether the meter has been exposed to magnetic influence or the
meter over has been dismounted (access control).
The status logger has a depth of 200 loggings.
3.6.6 Event logger for RTC
A logger in the meter stores information about changes/adjustments of the clock in the form of date/time before
and date/time after adjustment. Only adjustments of a specific size will be registered in the lock. The minimum
time for an adjustment to be logged is configurable, and the default value is 7 seconds. The value range is
between 0 and 255 seconds.
The RTC logger has a depth of 200 loggings.

The logging depth of the analysis logger depends on the integration period of the load profile logger. The stated
logging depths are calculated on the basis of an integration period of 15 min.

3.6.7 Event logger for voltage quality
Voltage failures are possible on one or two independent phases or on all three phases. The lmeter registers
voltage failures that last longer than minimum 1 second. No matter how many phases the voltage failure applies
to, the time of the voltage dropout will be registrered, and it will also be registered when the voltage returns, as
described in Figure 6. The logger stores the phases that the failure applies to and during which period.
Voltage failure is defined as voltage below 160 VAC 5 %. The voltage failure logger has a depth of 200 loggings.
3.6.8 Event logger for the load profile logger
The logger registers all changes in the legal logger. A change in the configuration of the legal logger will, as
mentioned in a previous section, mean that all data in this legal logger are deleted. Therefore, every change in the
legal logger is registered with a timestamp. The event logger has a logging depth of 10 loggings.
3.6.9 Event logger for Cut off
A meter with breaker includes a logger that registers all events related to the disconnect functionality. For each
event, that be a disconnection, a release or a reconnection, the meter logs an ID, a timestamp, the disconnect
state (according to Figure 18) and the connection feedback.
3.6.10 Event logger for neutral fault
The logger registers errors in the supply network. The purpose with this logger is to register if the attached
electronic equipment is exposed to overvoltage, which can damage the equipment and/or cause injury to person
due to fire.
In meters with build in breakers, there is furthermore a possibility to switch off the supply out of the meter in case
of neutral fault detection.
Neutral fault detection only applies to the three-phase, 4-wire metertype.
Figure 8 illustrates when a missing or faulty neutral is detected.
Figure 8: Neutral fault detection.
This means it is only possible to detect missing or faulty neutral before the meter(marked green), not after the
meter(marked red).
The neutral fault detection is based on voltage measurements and voltage thresholds.

Figure 9: Neutral fault measurement principle.
Figure 9 shows a situation without neutral fault and one with neutral fault. When the netraul fault is present the
load is asymmetric and the neutral fault voltage VN occurs.
The green vectors indicate the phase voltages on the grid. The yellow vectors indicate the phase voltages
measured by the meter.
The neutral fault is detected, when the following conditions are present:
Two of the phase voltages VL1, VL2 and VL3 must be above the threshold voltage VLHiTh.
One of the phase voltages VL1, VL2 and VL3 must be below the threshold voltage VLLoTh.
Condition 1 and 2 must be present in a time period longer than the period Time.
VLLoTh = 230V - VNTh

In Figure 10 to the left, the yellow areas indicate when the neutral fault will detected.
Figure 10 to the right shows a situation where the neutral fault is detected, where the conditions are:
VL1 < VLLoTh

The parameters VNTh, VLHiTh and Time can be configured with the registers: (shown with default values)
NeutralFaultVNTh = 40 VAC
NeutralFaultVLHiTh = 253 VAC
NeutralFaultTime = 60 s
Under some conditions a neutral fault is not detected. In Figure 10, fault is not detected in the white areas.
In conditions with symmetric load the neutral fault voltage VN will theoretically be zero volts and neutral fault will
not be detected, even if the neutral is missing. Table 8 lists the parameters that are logged in the neutral fault
logger.

3.7 Pulse inputs/outputs
As default the meter has an S0 pulse output (described in section 3.7.5) and two available I/O (input/output)
ports in the module interface. The use of one or both I/O ports in the module area requires that the meter is
equiped with a primary module that supports the wanted functionality.
The S0 output provides 1000 pulses/kWh permanently, whereas the I/O module is configurable as to length and
number of pulses. The S0 output always follows the blinks from the LED light-emitting diode.
3.7.1 Pulse inputs in the module area
The pulse inputs in the module area (module I/O) can be configured for the following functions depending on the
meter’s configuration:
- Tariff control, see also Table 2.
- Pulse input from other units.
- Alarm input for the registration of an external alarm.
The pulse input accumulates pulses in the pulse input register. If this reigister is shown in the display, it is
updated every 10 seconds. It is possible to scale the reading of the pulse input by a ”pulse division factor” in the
range from 0.100 to 1000.000 units per pulse. The maximum permissible frequency for input pulses is 25 Hz.
In connection with the pulse input register, the following units can be selected: kWh, m
3
, l,”none”.

The alarms will be transmitted via Kamstrup radio communication (if the meter is with Radio) for use in Kamstrup
AMR systems, or on the module port. For further details about alarms and configuration, please contact Kamstrup.
3.10 Load control
As an option it is possible to mount a two relay load control module in the meter. The relays can be used to
control (On/Off) external installations. The control of the relays can be done by:
- Predefined (configurable) Load control tables - managed by the meter.
- By remote command – managed by system.
See more about configuration of the load control in section 10.4.

4.1 Value field
This field is used for displaying register values. The number of register values depends on the meter's
configuration. The value field reading depends on the value stated as well as the meter’s set-up. Meter numbers,
special data etc. are indicated by 8 digits, energy is stated in [6.1], or [7.0] format kWh/kvar, and power in [2.3]
format (00.000) kW/kvar. Date/time is stated according to the format YY:MM:DD and HH:MM:SS.
The value field can be configured to display leading zeroes of energy readings.
4.2 Unit field
The unit field is used for displaying the units of registers in the value field.
4.3 Text field
The text field can be used either for additional information to the unit field regarding values in the value field or
for text information. In the latter case, text messages are shown as sliding letters in the field.
4.4 Mains voltage reading
The mains voltage readings per phase L1, L2 and L3 indicates whether voltage is applied to the individually
phase input terminal or not.
Indications L1, L2, L3 Indicate
On The voltage is above minimum limit (160V).
Off The voltage is below minimum limit (160V).
Table 13: Main voltage indication.
The minimum voltage limit is 160 VAC 5 %. If the voltage remains below minimum limit for more than 1 second
in all phases, the meter is reset and the processor shuts down. Subsequently, the meter carries out a normal
start.
4.5 Phase current indication
The direction of the current for each phase is shown with these indicators. It can be useful when checking of
correct input/output installation.
Indications - + Indicate
On The load is above minimum limit (2.3W).
Off The load is below minimum limit (2.3W).
Table 14: Phase current indication.
The minimum load limit is approx. 10 mA. If the phase current is lower than this value, energy registration stops
and the phase current indication turn off in the display.

4.6 Tariff indication
The tariff indicator can show T1, T2, T3, T4, T5, T6, T7 and T8 to indicate the currently active tariff. The tariff
reading is updated every 10 sec., i.e. it may take up to 10 seconds from a tariff shift until the current reading is
displayed.
The tariff indication are switched off if a display configuration without tariff reading has been selected.
4.7 Current quadrant reading
The total load is indicated by the arrows for imported active power, exported active power, inductive reactive
power and capacitive reactive power, respectively.
The current quadrant reading is an instantaneous total value for all three phases. The reading is not active when
the load is below the minimum limit of 10 mA RMS.
This reading is On/Off-configurable.
4.8 Breaker status
If the meter is configured with an internal breaker, the position of the breaker is indicated as either connected or
disconnected.
4.9 Object identification field

4.10 Display configuration
The display configuration is composed by three reading lists which can be configured as required. However, legal
readings are mandatory and cannot be deselected of the lists.
The automatic shift function (scroll) changes every 10 seconds between the selected readings in the required
order. Up to 16 readings can be selected.
At the manual shift function, the shift is effected when activating the push button. The shift is effected when you
release the push button. Again, the order is configurable and up to 30 readings can be selected.
If the meter is configured with battery backup unit, it is possible to select a battery-operated shift function, which
makes it possible to read the display without the meter being mains supplied. The shift is effected by activating
the push button. Up to 8 readings can be selected.
The meter automatically returns from manual shift function to automatic scroll function two minutes after the last
activation of the push button.
The display reading can be composed e.g. as shown in the example below. To view a complete list of possible
display readings, see 10.3 Display readings.

5 Integrated radio
This applies to meters with integrated radio.
5.1 Communication via radio
The meter can be ordered as a variant with an integrated radio “module”. It is used for the establishment of
remote reading in a Kamstrup AMR system.
If the meter is supplied with integrated radio, the meter will automatically try to connect to a radio network.
The integrated radio is equipped with an internal antenna. The radio signal strength can be read by hand-held
terminal. If the radio signal is too suppressed, an external antenna must be connected to increase the signal
strength. Connect the external antenna to the antenna plug that is located to the left of the display.
By using a hand-held terminal, it is possible to read the meter and thereby ascertain that the integrated radio is
running.
Mounting a communication module in the module area may influence communication. Please contact Kamstrup
A/S to obtain additional information.
5.2 Software upload
It is possible to upload new radio software remotely via en AMR system. Please contact Kamstrup for further
information regarding the radio software upload functionality.

6 Integrated disconnection
This applies to meters with integrated breaker.
The breaker function is controlled by the meter’s main processor and consists of bistable relays that maintain
their disconnection status independently of the supply to the meter.
The breaker disconnects the phases of the meter. The neutral connection is not disconnected.
6.1 Disconnect function in the meter
Meters with integrated disconnection brakers can cut off/disconnect the consumer’s supply.
Do not use the function as safety cut-off.
It is possible to disconnect the meter in 4 ways:
- Manually by activating the push button
- Remotely controlled via a communication command in the reading software
- Intelligent disconnection via current or power (smart disconnect)
- Prepayment.
It is possible to reconnect the meter in 4 ways:
- Manually by activating the push button
- Remotely controlled via a communication command and activating the push button
- Remotely controlled via a communication command and an additional communication command
- Automatically after smart disconnect or prepayment.

6.2 Manual disconnection and connection
It is possible to disconnect the meter manually. This is done in the following way:
1a) On the meter, select the below display reading by activating the left push button:
L1
L2 L3
1b) Activate the left push button for approx. 6 secs. This will disconnect the relays, and the red diode turns on.
Manual reconnection is done in the following way:
2a) On the meter, select a display reading that is different from the reading selected in 1a).
2b) Reconnection is possible when the diode emits green light and 1 minutes after disconnection.
Activate the left push button for 6 secs. until the relays are connected and the green diode is turned off. If
the relays are not connected after 6 secs., wait 1 min. and reactivate the left push button for 6 secs.
6.3 Disconnection by means of communication commands
Meters with breakers can also disconnect remotely via commands. Both the DLMS and KMP protocols permit to
disconnect, release and reconnect the supply to the consumer remotely via a communication network or locally
be means of e.g. the configuration tool METERTOOL.
There is a predefined 60 seconds hardware timer for the disconnection/connection function, meaning that you
must wait 60 seconds after a disconnection before the relays can be reconnected. The time is configurable, but
has to be 60 seconds as a minimum.

6.4 Smart disconnect
Smart disconnect activates the internal relays when exceeding a preprogrammed limit. The meters can be
programmed with a current or power limit that, when it is exceeded, will disconnect the supply to the consumer.
As default, the meter is provided with the smart disconnect function. If the function is to be used, it must be
activated from the factory at delivery, or it can be activated with METERTOOL.
Be aware that the JJ code can only be changed via the module port, not via the optical head.
At configuration, the cut-off current I
disconnect
(Id) or the cut-off power P
disconnect
(Pd) is programmed, and the cutt-off
configuration (JJ, see 10.2.3 Configuration 3 ( JJ-K-LL-M-NN )) is configured to cut off at either current or power.
The meter will disconnect the consumer when I

6.4.2 Overcurrent protection
To secure the breaker against overcurrent e.g. at short circuits, the meter has an upper limit, the short circuit
current I
k
. If the current exceeds this limit, the breaker does not disconnect. Thus, the risk of defects is minimized.
6.4.3 Current-controlled disconnection
Current-controlled disconnection is based on RMS current with average determination every 1 sec. Disconnection
is effected if one of the phase currents I
L1
, IL2, IL3 exceeds the limit Id*kx for a configured time period; t1, t1+t2 or
t
1+t2+t3
.
6.4.4 Power-controlled disconnection
Power-controlled disconnection is based on the total power. Disconnection is effected if the total phase power
exceeds the limit I
d*kx
for a configured time period; t1, t1+t2 or t1+t2+t3.
6.4.5 Reconnection
Reconnection can be configured to be either manual or automatic. No matter if manual or automatic reconnection
is selected, reconnection cannot be effected until after the wait time, t
reconnect
since reconnection, has expired.
6.4.6 Disconnection basis
Disconnection basis decides if smart disconnect or prepayment is active and on which basis the disconnection is
effected. It is possible to select:
- No function: The smart disconnect function is deactivated.
- Power-controlled: Disconnection is effected when a programmed power limit is exceeded.
- Current-controlled: Disconnection is effected when a programmed current limit is exceeded.
- Prepayment: The prepayment function controls the disconnection. See section 6.5.
Disconnection basis is selected as part of the disconnection configuration, see section 10.8.
6.4.7 Disconnection status
It is possible to read the status of the output voltage per phase to verify that disconnection has been effected
and, otherwise, to ensure that all phases are connected.

6.5 Prepayment
The prepayment function is to be used with a reading system prepared for communication with Kamstrup
electricity meters or with an external unit prepared for payment control. Prepayment is only possible for meters
with internal breaker, and will not work together with tariffs.
Be aware that the JJ code and A
14prepayment
can only be changed via the module port, not via the optical head.
The prepayment function is as standard integrated in meters with breakers and can be activated and deactived as
required. When A
14prepayment
has reached 0 kWh, the supply to the consumer is disconnected, and a new value for
the register must be programmed.
When prepayment is activated, the countdown register A
14prepayment
is not automatically activated in the display
settings. This has to be done manually by using a display setup that includes the prepayment register. When a
display setting with the A
14prepayment
register is activated, the register is only shown when prepayment is enabled.
The unit in the display is “kWh” and “PAY” is shown in the text field. The prepayment is based on the total A+
register, and therefore, it is disregarded if the meter is configured for tariffs.
When prepayment is deactivated, the A
14prepayment
is reset. The A
14prepayment
-register cannot be reset in other ways.
The minimum and the maximum values for the prepayment-register depend on the formatting of the energy
display.

on a non-workingday or exceptionsday, the disconnection will happen at the firstcoming workingday.
When A

has reached 0 kWh, and the relays are disconnecting, it will be possible to decrease the load,
reconnect the meter and by that still be able use a minimum of current or power. The limits, called I

The minimum limit secures that the consumer, who has been disconnected, can reduce his consumption and
hereafter reconnect in order to maintain energy for e.g. essential appliances.
At configuration of disconnect values, the following applies:
- I

is a time limit for the duration in which the exception for current and power, respectively, can be active.
When the limit is exceeded, the consumer is disconnected. When A

6.7 Disconnection on meters with APS
On meters with APS (Auxiliary Power Supply), the disconnection functionality is slightly different from mentioned
in the previous chapters.
When the APS meter is supplied with the mains as well as APS the functionality is the same as above.
The reason that the meter operates different is that the coil that activates the breakers only has power for one
operation when supplied by APS.
6.7.1 Using the push button
The meter is supplied with mains and APS. The main switch is switched off, means the meter is only supplied
from APS. In the display reading “dCon”, pressing the left push button for approx. 6 seconds, the meter
disconnects and the diode turns to red for one minute and after one minute is turns to green.
It is not possible to reconnect the meter as long as it is only supplied from APS.
6.7.2 Using commands (remote)
Meter is only supplied by APS.
Relays in state 04, connected, diode off.
Command send for disconnect.
- Relays in state 01, disconnected, diode turns to red.
Command sends for disconnect – ready to reconnect.
- Relays in state 08, disconnected, diode turn to green.
Command sends for reconnect.
- Relays in state 04, diode off, BUT relays NOT connected.
Mains supplied to the meter.
- Relays in state 04, diode off, BUT relays NOT connected. After connection the mains to the meter, it can take
up to one hour before the meter reconnects the relays and provide supply to the consumer.

7 Meter communication
Kamstrup’s electricity meters have internal communication protocols for communicating both via the optical head
and the module connector placed in the module area. The meters enable communication via Kamstrup’s own
optimized protocol KMP.
It is possible for a third party to use the module area of the meter, described in section 8.2.2, for specific
developed modules, and in this connection to use one of the internal protocols implemented in the meter.
7.1 Requirements for third party modules
Below, the minimum requirements for developing modules for Kamstrup’s electricity meters are described.
In general, the design of the module must conform to written and unwritten rules of electrical constructions.
Requirements:
- Optocouplers must be applied in all connections between module and module connector to avoid
external noise influencing the meter.
- The module must use the powerful current supply of the meter.
- It is the responsibility of the third party to secure that the module mounted in a Kamstrup electricity
meter conforms to relevant standards for both meter and module. Kamstrup must accept the results of
these tests. Please contact Kamstrup A/S for further information.
- The module must be CE labelled.
- Kamstrup must have two modules for testing purposes before the first delivery is made to the
customer.
7.2 KMP
The KMP protocol gives access to all registers in the meter and enables programming and set-up. Please contact
Kamstrup A/S for requesting a copy of the protocol.

10.4 Period plan - Tariff and load control table
The period plan contains tariff control table and plans for control of one or two load output, independently from
the tariffs.
In the following is shown an example of a setup of the tariff plans by use of METERTOOL.
Making a period plan, the following has to be considered:
Working days – Non working days
Period change time (often same as summer time – normal time, also called Period A and Period B in
METRTOOL. This with a resolution of 1 minute)
Tariff changes (up to 8 changes per day is possible. This with a resolution of 1 minute)
Exception days
Load control 1
Load control 2
Below show an example of a tariff plan.
10.4.1 Setup working days and non-working days
Each day of the week can be set to either a working or a non-working day.
10.4.2 Setup period A and B and tariff switch for each period.
A calendar year can be split in two periods – period A and period B. Each period is set with a start date and a
number of tariff changes (each containing a time for change and the tariff to be entered) for both working-days
and non-working days.

10.4.3 Setup plan for load control 1 and 2
If the meter is installed with a load control module, it can be configured to include a plan for the switching
between active and inactive. A separate plan can be made for both relays.
The load control can also be configured to follow the tariff. For each tariff that are defined in the tariff plan, it shall
be defined whether the relay shall be active or inactive.
TECHNICAL DESCRIPTION Kamstrup 162M/382M
5512-1040 GB/05.2012/Rev. C1
64
10.4.4 Setup calender for exception days
Also it is possible to define a number of exception days that will be as the non-working regarding tariff changes. A
number of up to 100 exception days can be configured separately for tariff plan and for both load control plan 1
and 2.
10.4.5 On Demand tariff
By the system it is possible to to overrule the internal tariff plan by a OnDemand command. This command force
the meter into a specific tariff for a time period.
10.4.6 Load control delay
The load control works together with a random delay. The delay is variable and calculated individual in every
meter.
The delay can be between 0 – 10800 seconds.
The delay is only added when the relay changes from inactive to active. When changing from active to inactive,
the delay is not added.

10.5 Daylight saving table
This table indicates on which dates the meter’s clock (RTC) is to change between daylight saving and normal time
if the meter has been configured to do so.
It is possible by system to update this table. An example of a daylight saving table is shown below.
When Daylight saving time is aneabled, it is taking into account when the meter is using the tariff and load control
functionality described in section 10.4.
Also all timestamps that are read out in the display, e.g. the load profile as shown in Figure 15 and the read out of
historical data, is taking the daylight saving time into account.
However, all event loggers, i.e. voltage quality logger, status logger, RTC logger, cut off logger and neutral fault
logger does not take the daylight saving time into account when a time stamp is made to an event for one of the
mentioned loggers. Also time stamps related to peak values doesn’t take daylight saving time into account.

10.6 Label
The label consists of two labels: a meter label describing the choices made under type number, and a customer
label created on basis of the customer's wishes, and which the customer must approve before an order can be
created to the customer.
Four standard customer labels without customer logo are available.
These standard customer labels are:
2019000 No bar code No meter number
2019001 Code 128 Meter number = serial number
2019002 2 of 5 interleaved Meter number = serial number
2019003 Code 39 Meter number = serial number
The following information is required for the creation of a new customer label:
Customer logo must be provided to the Electricity Product Group. The logo must be in black/white and in one of
the following formats: JPG, WMF.
Information about the bar code type to use and its content, serial number, meter number, installation number,
and the position of numbers and bar code must also be provided.
When all information is available, a draft is prepared, which must be approved by the customer. The bar code
should also be read by the customer in order to secure that his/her bar code reading device can read the bar
code.
After approval, a customer label no. 2019XXX is selected, and the number is released in Kamstrup ordering
systems.
