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 product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation for the specific task, in particular its warning notices and
safety instructions. Qualified personnel are those who, based on their training and experience, are capable of
identifying risks and avoiding potential hazards when working with these products/systems.

Description 3
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.

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.
Measurement
● Derivation of more than 300 measured variables from the basic measured variables with
maximum and minimum values (min/max 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.
● Calculation of genuine r.m.s values for voltage and current to the 63rd harmonic
● 4-quadrant measurement (import and export)
● Zero blind measurement
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.
