Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes
in this documentation qualified persons are defined as persons who are authorized to commission, ground and
label devices, systems and circuits in accordance with established safety practices and standards.

Description 3
3.1 Features
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 is an ideal replacement for all
conventional analog indicating instruments.
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 active energy and reactive energy counter, a
universal counter, and an operating hours counter for monitoring connected loads. A
comprehensive, parameterizable signaling system allows application-specific monitoring of
various events, such as limit violations or operator interventions.
The volatile memory of the device and the internal clock are battery-backed.
The integral Ethernet interface or an optional expansion module can be used for
communication.
SENTRON PAC4200 has two multifunctional digital inputs and two multifunctional digital
outputs.
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.

Measurement
● Derivation of more than 300 measured variables from the basic measured variables with
maximum and minimum values (slave pointer function).
● At the voltage terminals, SENTRON PAC4200 can be connected direct to 690 V industrial
systems (max. 600 V for Vph, measuring category III, pollution degree 2). Higher voltages
using voltage transformers.
● For current transformers x/1 A and x/5 A. Conversion ratio and current direction
programmable.
● Can be used in 2-, 3- and 4-wire systems. Suitable for TN, TT and IT systems.
● High measuring accuracy: For instance, accuracy class 0.2 in accordance with IEC
61557-12 for the active energy, in other words accuracy equivalent to 0.2% of the
measured value under reference conditions.
Sliding window demand values
● Calculation of the sliding window demand values for
– Voltages and currents
– Power factor per phase and total system
– Apparent, active, and reactive power per phase as well as total power
● Maximum and minimum values of the sliding window demand with the date and time of
occurrence since startup, the last reset, or the last deletion
● Demand calculation for reactive power VAR1, reactive power VARn, or total reactive
power VARtot.
● Configurable averaging time.
Average values over all phases
● Calculation of the average voltage and current values over all phases. The average value
of a three or four-phase system corresponds to the arithmetic mean for the individual
phase values.
● Maximum and minimum average values with date and time.

Counters
● A total of 10 energy counters capture reactive energy, apparent energy, and active
energy for off-peak and on-peak, import and export.
● Configurable universal counter for counting
– Limit violations
– Status changes at the digital input
– Status changes at the digital output
– Pulses of a connected pulse encoder, such as electricity, gas, or water meters. The
pulse shape and dynamic response must correspond to the signal shape described in
the IEC 62053-31 standard
● Operating hours counter for monitoring the operating time of a connected load. Counts
only in the case of energy counting above an adjustable threshold
Monitoring functions
The following can be monitored:
● 12 limits The limit values can be logically combined. A group message that indicates the
violation of at least one limit value can be generated.
● Direction of rotation.
● Status of the digital inputs.
● Operating status of SENTRON PAC4200.
● Resetting the device and the communication parameters to the factory default settings.
● Deleting recorded load profiles and events
● Resetting counter values
● Reboot after losing the power supply.
● Changing the date and the time.
● Changing device parameters.
● Writing a large number of events in the event memory.
Events and messages
● Recording up to 4096 events with a time stamp and event-specific information.
● Displaying the events in an events list.
● Reporting the events on the display.
● Classifying the messages as information, warnings, or alarms.
Displays and controls
● Large backlit graphics LC display for optimal readability even from a distance.
● Menu-driven parameterization and operation with plaintext display.

MODBUS RTU protocols are passed on direct to the subordinate devices.
Internal clock
● Time stamping of events.
● Synchronization of the load profile as an alternative to external synchronization.
● Battery backup.
Long-term memory
● Storage of load profiles.
● Storage of events.
● Battery backup.
