Ref. no. 2103 REG ES
1.2. Application purpose
The energy counter detects the active energy supplied or drawn from the mains for
up to three phases with a high level of accuracy.
In addition, the energy counter also records voltage, current, active power, reactive
power and frequency. The resulting energy costs are calculated for up to three
Rates.
With the aid of integrated monitoring functions, peak loads can be detected, reported
and avoided by means of additional measures.
All information, limiting values and measured values are accessible via KNX
telegrams.
The device is suitable both for direct current measurement and for current
measurement with external current transformers. The connection of external current
transformers allows the measurement of greater currents of up to 75 A. Accordingly,
higher outputs can be recorded.

Mounting and electrical connection
Ref. no. 2103 REG ES Page 8 of 44
NOTE: The mains infeeds L1, L2 and L3 must be protected with ≤16 A.
NOTE: L2 and L3 are not required for the operation of the energy counter and
can be optionally left out, as the device is only supplied via L1 on the mains
side.
3.2. Operation with external current transformers
If the device is operated with external current transformers, then the external current
transformers are to be installed in a distribution cabinet on a DIN rail according to
DIN EN 60715.
The device only supports external current transformers with a primary current of 75 A
and a 5 A secondary current. We recommend using the same transformer type for
each of the three inputs of the energy detector 2103 REG ES. Current transformers
of type PACT MCR-V1-21-44-75-5A-1 (PHOENIX CONTACT Reference number
2277611) are recommended with the accessories of the support rail adapter PACT
MCR-RA (PHOENIX CONTACT Reference number 2277598).
The accuracy of the measurement is primarily dependent on the current
transformer type used.
3.2.1. Mounting and connection
DANGER!
Electric shock when live parts are touched. An electric shock can be
fatal.
Before working on the device, disconnect the connection cables and
cover live parts in the area.
Do not remove the housing cover! Dangerous voltages may still be
present even after removing the connections!
In transformer mode, the external current transformers are also to be
regarded as live on the secondary side.

Mounting and electrical connection
Ref. no. 2103 REG ES Page 9 of 44
Connection diagram for current measurement using current transformers
Snap the device onto the DIN rail. The terminals for the mains should be
located at the top.
If the device is operated with external current transformers, then connect
according to Fig. 3.
When connecting the cables to the screw terminals of the device, the neutral
conductor must be connected to the device first. On removal, the neutral
conductor must be disconnected from the device last.
NOTE: A load must always be inserted between the output and the neutral
conductor (>< symbol). The output and neutral conductor may not be
connected without a load.
The mains voltage infeed lines to the primary sides of the current transformers
must be protected according to the primary rated current and the current
rating of the cable with F1, F2, F3 fuses (max. 75 A).
The secondary sides of the current transformers are connected in a single-
pole manner to the mains voltage using a cable to be protected with the rated
current of the energy detector 2103 REG ES. The poles of the secondary
sides of the current transformers are to be connected using the inputs E1, E2
and E3 of the energy detector 2103 REG ES. The cable cross-section must be
2.5 mm

Commissioning
Ref. no. 2103 REG ES Page 10 of 44
3.2.2. Operational instructions
During operation with open secondary sides, high voltages can occur on
current transformers. For this reason, the current transformers must always be
connected to the inputs E1, E2, E3, before reconnecting the primary circuit.
The connection of the current transformers to the inputs E1, E2 and E3 of the
energy detector 2103 REG ES prevents such surge voltages.
The connection of the secondary sides of the current transformers with the
input voltage means that the current transformers and their connections have
a 230 V voltage potential.
The secondary sides of the current transformers are therefore live parts and
must be covered, so that cannot be touched after installation.
4. Commissioning
DANGER!
Electric shock when live parts are touched. An electric shock can be
fatal.
Before working on the device, disconnect the connection cables and
cover live parts in the area.
Do not remove the housing cover! Dangerous voltages may still be
present even after removing the connections!
In transformer mode, the external current transformers are also to be
regarded as live on the secondary side.
After setting the physical address, loading the application by means of ETS and
connecting to the mains voltage, the energy counter is ready for operation.
The Power LED lights up continuously if the energy counter is in operation and the
energy saving mode is not active. Channel LEDs E1, E2 and E3 indicate the
measurement of an energy amount of 1/6400 kWh at the respective channel by
lighting up briefly.
If the Power saving mode is activated, the Power LED goes out and no energy is
counted.

5.2. Overview
5.2.1. Measured values
Diagram - Measured values
The energy detector permits the monitoring of electrical loads to up to three phases
with a shared neutral conductor. Each channel can measure:
−Voltage (rms value)
−Current (rms value)
−Active power
−Reactive power
Additionally, active power and reactive power are added up across all channels as
three-phase current variables, and also the mains frequency is provided.
According to the configuration, the measured values will be transmitted to the KNX
bus, either cyclically and / or on a change or explicit request. For some variables, a
telegram is transmitted if a limit value is fallen below or exceeded.
The measured values are calculated in intervals of one second.
The transmission process is distributed over a time period of one second in
order to reduce the bus load.

Application
Ref. no. 2103 REG ES Page 13 of 44
5.2.2. Energy counter
The device possesses 32 counting units (hereinafter referred to as counter), which
count the electrical energy. Exactly one communication object of type DPT 13.010 is
assigned to each of these counters and their value reflects the current counter level
or the counter in Watt/hours. The following figure shows an overview of the counters
of the device:
Overview of all energy counters of the device
All the counters of a device each count the active energy measured in the
appropriate channel. Mathematically, the counting of the active energy corresponds
to a temporal integration of the active power. Thus, a counter only counts when the
basic active power does not equal zero. The counting is balanced, i.e. if the active
power is positive, then the counter increases. If it is negative, then it decreases. A
negative active power corresponds to a reverse output flow. The balanced counting
means that the counter level can contain both positive and negative values.
Fig. 6 shows the relationship between the appropriate counters and the
corresponding active power. The counters of Channel 1, 2 or 3 are alternating current
counters, which only count the energy in one channel or one phase. By contrast, the
counters for the three-phase current count the total energy flowing in all three
channels or all three phases.
In addition, each type of counter possesses special characteristics. These are shown
as a comparison in the following table:

Table 1: Properties of the energy counters, where Rate n
stands for the three Rates 1, 2 and 3.
As the table shows, the counters "Counter, Rate n" and "Current counter, Rate n"
only count when the appropriate Rate is currently active. Rates 1, 2 and 3 exist. They
can be activated or deactivated independently of one another. In so doing, activation
or deactivation occurs either using configurable times or using the "Rate switch"
object on the bus.
According to Table 1, the reset of the intermediate counter is controlled either using
the activation or deactivation events of the Rates or using trigger objects, of which
two are available for each intermediate counter.
If an intermediate counter is controlled using the activation or deactivation object of a
Rate, i.e. the corresponding parameter "Via Rate parameters" is set for the
intermediate counter, then the Rate counter always resets itself to zero at the
beginning of the appropriate Rate.
If, by contrast, the parameter "Via trigger objects" is set for an intermediate counter,
then two trigger objects are available for each intermediate counter. When Trigger 1
is received, the intermediate counter is reset and restarted. When Trigger 2 is
received, the counter level of the intermediate counter is transmitted on the bus. In
addition, it is possible to configure whether receipt of Trigger 2 also causes a stop.

Application
Ref. no. 2103 REG ES Page 15 of 44
The counter levels are calculated in intervals of one second.
If there is a power failure to the KNX system, the values of the energy counters (but
not the 1/4-hour counters) are backed up and reloaded to the appropriate
communication objects on restarting.
5.2.3. Rate counters
In addition, the device possesses three counting units (hereinafter referred to as cost
counters), which count the costs for each Rate. Exactly one communication object of
type DPT 13.xxx is assigned to each of these counters and their value reflects the
current cost level in Euro cents. The following figure shows the three cost counters in
relation to the basic measurand and the three-phase current counters:
Calculation of the cost counters
As Fig. 7 shows, all three Rate-related three-phase current counters are derived from
the measurand of the active three-phase current power. This is counted in the time
during which the appropriate Rate is active (or mathematically integrated by time).
The value of a cost counter results from the multiplication of the three-phase current
counter with the price of the appropriate Rate.
We would like to point out that the three-phase current counter values and cost
counter values shown in Fig. 7 can also be negative, if the basic active three-phase
current power is negative.

Application
Ref. no. 2103 REG ES Page 16 of 44
In this context, the resulting negative costs can be interpreted as a remuneration.
If there is a power failure to the KNX system, the values of the Rate counters are
backed up and reloaded to the appropriate communication objects on restarting.
The following table summarises the properties of the cost counters:
