Description
3.1 Performance features of the SENTRON PAC4200
SENTRON PAC4200 is a Power Monitoring Device for displaying, storing, and monitoring all
relevant system parameters in low-voltage power distribution. It is capable of single-phase,
two-phase, or three-phase measurement and can be used in two-wire, three-wire, four-wire,
TN, TT, and IT systems.
Thanks to its compact design in 96 x 96 mm format, it fits into any standard cutout. The
SENTRON PAC4200 measures around 200 electrical variables with minimum values,
maximum values and demands.
With its large measured voltage range, SENTRON PAC4200 with a wide-voltage power
supply can be connected direct in any low-voltage system up to a rated system voltage of
690 V (max. 600 V for Vph).
Higher voltages can be measured using voltage transformers. For measuring current, either
x / 1 A or x / 5 A current transformers can be used.
The large graphical LC display permits reading even from a distance. SENTRON PAC4200
has adjustable backlighting for optimal readability even under poor lighting conditions.
The combination of four function keys with the multi-language plaintext displays makes
intuitive user prompting possible. The experienced operator can also use direct navigation
for quicker selection of the desired display menu.

SENTRON PAC4200 guarantees high measuring accuracy. It can be used to capture and
store load profiles according to various methods. It has a range of useful monitoring,
diagnostics, and service functions, a two-tariff apparent energy, active energy and reactive
energy counter, two universal counters, and an operating hours counter for monitoring
connected loads.
The SENTRON PAC4200 saves the apparent, active and reactive energy consumption per
day and tariff over one year. In addition, the Power Monitoring Device has an apparent,
active and reactive energy counter for recording the energy consumption of a manufacturing
process. A separate operating hours counter calculates the duration of this process. The
available digital inputs are used to control the process energy counters.
A comprehensive, parameterizable signaling system allows application-specific monitoring of
various events, such as limit violations or operator interventions.
The data memory of the device and the internal clock are battery-backed.
The integral 10 / 100 Mbit Ethernet interface or an optional expansion module can be used
for communication, e.g. the SENTRON PAC RS485 expansion module or the SENTRON
PAC PROFIBUS DP expansion module.
SENTRON PAC4200 has two multifunctional digital inputs and two multifunctional digital
outputs.

Description
3.1 Performance features of the SENTRON PAC4200
With optional SENTRON PAC 4DI/2DO expansion modules, it is possible to expand the
SENTRON PAC4200 with up to 8 digital inputs and up to 4 digital outputs. This makes a
maximum configuration of 10 digital inputs and 6 digital outputs possible. The external digital
inputs and digital outputs have the same functions as the integral digital inputs and digital
outputs. Thanks to the internal power supply, the digital inputs and digital outputs of the
expansion modules can be used as S0 interfaces in accordance with IEC 62053-31. This
also enables the use of simple floating contacts for wiring the digital inputs.
The parameters can be set either direct on the device or with the SENTRON powerconfig
configuration software.
Password protection is integrated to guard against unauthorized access.

3.3.1 Sliding window demand values
The sliding window demand value is the arithmetic mean of all measured values that occur
within a configurable averaging time. "Sliding" means that the interval for the demand
calculation is continuously shifted as a function of time.

The sliding window demand values are updated 60 times per set averaging time. A lower
limit of 200 ms applies here. If an averaging time of 3, 5 or 10 seconds is set, the demand
value is formed with fewer values.
Available sliding window demand values
SENTRON PAC4200 supplies sliding window demand values for a large number of
measured variables:
● Per phase or as a total value over all phases
● With the maximum and minimum values as well as the time stamp for the maximum and
minimum values
The "Measured variables – overview" table above lists the available sliding window demand
values.
The sliding window demand values are represented on the display and can be called via the

3.4 Load profile
3.4 Load profile
3.4.1 Overview
The load profile records the time history of the electric power and thus documents the
distribution of power fluctuations and peaks.
SENTRON PAC4200 supports load profile recording according to the "fixed block" or "rolling
block" method. With both methods, the load profile is stored in the device and made
available at the communication interfaces.
SENTRON PAC4200 is capable of intelligently interpreting synchronization signals received
at irregular intervals. Any deviations from the set times are documented in the load profile.
Accessing the load profile data
Note
Data access via the software
Current and historical load profile data can only be accessed via the communication
interfaces. For more information, please see the related documentation.
Configuring load profile recording
You can adapt load profile recording using the configuration software or on the display of the
device. The following parameters influence the recording:
● Length of the demand period or subperiod
● Number of subperiods per demand period. This number defines the method for recording
the load profile ("fixed block" or "rolling block")
● Type of synchronization
You can also set the following parameter with the configuration software:
● Type of reactive power VAR
You can find more information about parameterization on the device display in the chapter
"Parameterizing", "Power demand".
Changing the configuration during operation: If the period length or the number of subperiods
is changed, this directly influences the load profile recording. The device stops the current
recording and clears all data in the load profile memory. Changing the configuration has no
effect on the device counter. The device is not reset.

Parameterizing the fixed block and rolling block methods
SENTRON PAC4200 supports the fixed block method as a special case of the rolling block
method. The most important distinguishing feature is the number of subperiods.
Number of subperiods:
The demand period can be divided into a maximum of five subperiods.
● The number "1" defines the fixed block method. In this case, the length of the subperiod
is identical to the length of the demand period.
● The numbers "2" to "5" define the rolling block method.

Length of the subperiods:
The length of a subperiod is an integer part of a full hour. The device allows the following
lengths in minutes:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 min
Length of demand period:
The length of the demand period cannot be directly configured. It is defined as the product of
the length of a subperiod and the number of subperiods.

Calculation of the power demand and the cumulated power
Arithmetic power demand:
Arithmetic calculation of the power demand referred to the actual length of the demand
period. The arithmetic power demand in the instantaneous period remains constant providing
the power is constant.
Cumulated power:

Cumulative calculation of the power referred to the configured length of the subperiod. The
cumulated power in the instantaneous period increases linearly providing the power is
constant.
The energy can be calculated from the cumulated power as follows:
Energy = (cumulated power) • (configured period length)

Description
3.4 Load profile
Storage capacity of the load profile memory
The data volume that occurs when a load profile is recorded depends on the length of the
period.
SENTRON PAC4200 can record load profile data for the following configuration over a
period of 40 days:
● Fixed block:
Length of the demand period: 15 minutes
● Rolling block:
Length of the subperiods: 15 minutes
This corresponds to a maximum of 3840 recorded periods.
This calculation applies to the ideal case in which the actual period length is identical to the
configured length for all periods over the complete load profile recording time. Any deviations
between the actual and configured period lengths additionally increase the data volume.
3.4.3 Current load profile data at the communication interfaces
Current load profile data
SENTRON PAC4200 supplies the load profile data for the current and instantaneous periods
at the communication interfaces.
● The current period is the last completed period.
● The instantaneous period is the period still in progress and has not yet been completed.
You can find more information on accessing the data via MODBUS in the Appendix.

Description
3.4 Load profile
Synchronization types
The device can obtain the synchronization pulse from an external source
● As a signal at the digital input,
● As a command via the communication interfaces.
The device can control the synchronization itself
● By means of the internal clock.
Handling of irregular, external synchronization pulses
SENTRON PAC4200 checks whether the external synchronization pulse is received at the
set time, too soon, too late, or not at all. If the deviation from the set time exceeds a defined
tolerance, this results in a shorter period.
If the complete time frame for received pulses is offset, SENTRON PAC4200 automatically
adapts to the new time frame.
Synchronization via the communication interface
The synchronization frame contains the length of the subperiod in minutes. The
synchronization command is ignored if the period length sent to the device with the
synchronization frame is different to the length parameterized in the device.
Synchronization with the internal clock
The length of the subperiod, and thus also the demand period, is determined solely by the
internal clock.
A subperiod starts on the full hour plus a multiple of the configured subperiod length.
Correction of the time during the current demand period or beyond the end of the demand
period results in shorter demand periods. SENTRON PAC4200 marks these periods with the
valuation indicator "resynchronized".
It does not record any substitute values for the gaps that are created in the time history.
Response to powering up
All load profiles that have already been recorded remain unchanged.
SENTRON PAC4200 resets the internal clock if it detects load profiles with a date in the
future or a time in the past on powering up.
Impact of a tariff change on the load profile
Tariff changes between off-peak and on-peak have an impact on the load profile because all
values stored in the profile are uniquely assigned to the applicable tariff.
The old tariff remains valid until the end of the instantaneous period. The new tariff takes
effect at the start of the next period. The energy counters of SENTRON PAC4200 are
switched to the other tariff at the end of the instantaneous demand period.

3.5 Tariffs
Impact of a measuring voltage failure
A failure of the measuring voltage has no effect on the load profile.
Impact of a supply voltage failure
The device records shorter periods if the supply voltage fails and when it is restored.
It does not record any substitute values for the duration of the power failure.
3.4.5 Additional information about the load profile data
SENTRON PAC4200 records the following additional information for each period:
● "Resynchronized"
The period was prematurely ended by the device owing to a synchronization irregularity.
● "Supply voltage failed"
The period was prematurely ended owing to the failure of the supply voltage.
● "Unreliable"
The load profile data is unreliable.
– The measuring current or the measuring voltage is outside the specified range.
– The reactive power type has changed.
The additional information is stored together with the other load profile data and can be
called via the communication interface.

3.5 Tariffs
SENTRON PAC4200 supports two tariffs for the integrated energy counters (on-peak and
off-peak).
Impact of the tariff change
The tariff change affects all energy counters for active energy, reactive energy, and apparent
energy.
Controlling the tariff change
A tariff change between off-peak and on-peak can be requested by means of a digital input
or via the communication interfaces.
Time-related switching is only possible using a higher-level system.

Activation of a tariff change at the end of a period
The old tariff remains valid until the end of the instantaneous period. The new tariff takes
effect at the start of the next period. The energy counters of SENTRON PAC4200 are
switched to the other tariff at the end of the instantaneous demand period.
Without synchronization, the tariff change takes effect immediately.

harmonics of the voltage referred to the root-mean-square value (r.m.s.) can be calculated
from this information in the software.
THD
The THD (total harmonic distortion) is used to describe the distortion of the electrical signal.
It indicates the ratio of the harmonic content to the fundamental in percent.
SENTRON PAC4200 measures the THD of the voltage and the THD of the current referred
to the fundamental. The instantaneous value, the maximum value and the time stamp of the
maximum value are supplied.
The values are calculated according to the IEC 61557-12 standard: 2007. Account is taken
of harmonics up to the 31st harmonic.
Displacement angle φ
The angle φ (phi) describes the displacement angle between the fundamentals of voltage
and current.
SENTRON PAC4200 supplies the instantaneous value of the displacement angle φ, the
maximum and minimum values, and the time stamps of the maximum and minimum values
for each phase.

The internal clock of SENTRON PAC4200 measures UTC time. All information about the
date and time (time stamp) that can be called at the communication interfaces must be
interpreted as UTC time.

Description
3.8 Limits
The SENTRON PAC4200 display indicates the configured local time corresponding to the
time difference due to time zones and daylight saving time.
UTC time: Universal Time Coordinated (UTC) is the international reference time.
Time zone: Geographical areas with the same positive or negative deviation from UTC time
are grouped together in time zones.
Local time: Local time is UTC time plus or minus the time difference due to the time zone
plus or minus the time difference due to the locally applicable daylight saving time.
Example: 3.36 p.m. CEST (local time in Germany) on September 10, 2008 corresponds to
1.36 p.m. (UTC time) on September 10, 2008. Germany is located in the UTC+1 time zone.
Daylight saving time applies on the above-mentioned date, so that the local time difference is
increased by one hour ("+1").
Synchronization of the internal clock
The internal clock of SENTRON PAC4200 can be synchronized with an external time, e.g.
with the "Top of minute" pulse or with a synchronization command via the available
communication interfaces.
Synchronization is relevant for all measured variables where the time of occurrence is also
captured, e.g. for recording the load profile.
3.8 Limits
SENTRON PAC4200 monitors up to 12 limit values as well as one limit that can be formed
by logically combining the other 12 limits.
Defining the limit values
The number of limit values to be monitored is selectable. The following must be specified for
each of the maximum of 12 limit values:
● Limit value monitoring ON/OFF
● Monitored measured variable
● Threshold
● Upper or lower limit violated
● Time delay
● Hysteresis
Combination of the limit values
The limit value formed by the logical combination is called "LIMIT LOGIC".
SENTRON PAC4200 provides parameterizable logic for combining the limit values that
supports brackets, takes account of priority rules, and allows logical negation.
The logic is represented on the display using the graphic symbols familiar from digital
technology: Four logic function blocks are connected upstream of one higher-level logic
function block. Each of the upstream logic function blocks has 4 usable inputs.

● XOR (EXCLUSIVE OR operation)
● XNOR (EXCLUSIVE NOT OR operation)
Any limit values and the digital inputs of SENTRON PAC4200 can be selected at the inputs
of the upstream logic function blocks. The input value is the truth value of the monitored
signal:
● True: Limit value is violated or input is active
● False: Limit value is not violated or input is not active
Displaying limit violations
SENTRON PAC4200 outputs limit violations at the digital output or via the interfaces.
Limit violations are countable. One of the limit values can be assigned to the universal
counters.
Limit violations are recorded as events with additional information on the monitored
measured variable and the monitored threshold.

Properties of the Ethernet interface
● Transmission rate 10 / 100 Mbit/s
● RJ45 socket (8P8C) on the top of the device for RJ45 connector with EIA/TIA T568B
assignment
● Cable type 100Base-TX (CAT5)
The Ethernet cable must be grounded for data transmission according to the Fast
Ethernet standard. You can find information on grounding in the "Connecting" chapter.
● Autonegotiation
● MDI-X auto crossover
● Communication over MODBUS TCP
NOTICE
Interference with other network nodes due to incorrect network settings
Incorrect network settings can adversely affect or interfere with the functions of other
network nodes The network settings for Ethernet are defined by the system
administrator and must be set accordingly on the device.
If the settings are not known, the (patch) cable must not be connected.
Autonegotiation is a method used by network communication peers to automatically
negotiate the highest possible transmission rate. SENTRON PAC4200 is automatically set to
the transmission rate of the communication peer if the latter does not support
autonegotiation.
MDI-X auto crossover describes the ability of the interface to autonomously detect the send
and receive lines of the connected device and adjust to them. This prevents malfunctions
resulting from mismatching send and receive wires. Both crossed and uncrossed cables can
be used.
3.11 Slots for expansion modules
Interface
SENTRON PAC4200 has two slots (MOD1 and MOD2) for installing optionally available
expansion modules.
Please consult the current catalogs to find out which modules are available for
SENTRON PAC4200.
One expansion module can be operated alone on the device or two expansion modules
simultaneously.

3.12 Gateway
SENTRON PAC4200 can be used as a gateway. This allows devices (slaves) that are
connected to the RS485 expansion module of PAC4200 to be connected to a device over
Ethernet (master).
Operating principle
Data sent by the master to the addressed target device: The higher-level software packages
the serial protocol into TCP/IP packets. SENTRON PAC4200 unpacks the TCP/IP packets
and forwards the freed packets of the serial protocol to the serial port (RS485).
Data sent by the addressed target device to the master: SENTRON PAC4200 packages the
serial protocol packets into the TCP protocol and forwards the packaged user data to the
higher-level software.

6.5 Grounding of the Ethernet cable
The Ethernet cable must be grounded for data transmission according to the Fast Ethernet
standard.
NOTICE
The upper limit values will be violated if the cable is not grounded
Compliance with the technical limit values for noise radiation and noise immunity is only
guaranteed if the cable is correctly grounded. The operator of the system is responsible for
ensuring compliance with the statutory limit values (CE mark).
Make a shield connection on both sides as described here.

6.5 Grounding of the Ethernet cable
Design
Ground the Ethernet cable at both ends. To do this, expose the foil shield of the Ethernet
cable. Connect the exposed shield to a suitable grounding point on the control cabinet,
preferably a shielding bus.
Figure 6-22 Grounding of the Ethernet cable
● Be careful not to damage the foil shield of the cable when removing the cable jacket.
● Fasten the exposed shield with a metal cable clamp or alternatively with a hose tie. The
clamp must clasp around a large portion of the shield and provide good contact.
● To allow good contact, a tin-plated or galvanically stabilized surface is ideal. With
galvanized surfaces, the contact should be achieved using suitable screws. A painted
surface at the contact point is not suitable.
NOTICE
Loss of contact if the shield connection is incorrectly used for strain relief
If the shield connection is used for strain relief, the grounding contact can deteriorate or
be completely lost.
Don't use the contact point on the cable shield for strain relief.
CAUTION
Damage to Ethernet Cable Shield due to Voltage Difference between Grounding Points.
If there is a voltage difference between grounding points, excessive current may flow
through the shield which is grounded at both ends.
In these cases, install an additional conductor in parallel with the Ethernet cable shield
to carry this current. Never interrupt the shield of the Ethernet cable.
