7KM PAC Measuring Devices
The 7KM PAC4200 provides comprehensive information
about events
Voltage failures, limit value violations, switching operations,
device configuration changes, counter resets or deleting of the
memory are just some of the possible events which the
7KM PAC4200 records and saves to the events list.
The integrated memory has space for more than 4000 operation,
control and system-related events, which the user can organize
according to his requirements.
For example, in addition to the three selectable alert levels for
information, warning or alarm it is possible to choose the priority
of each event independently of each other. And it is also possi-
ble of course to choose whether an event is to be recorded at all
and in which order the events are to be shown on the display.
Three-level event displays on the 7KM PAC4200
Events are displayed in three levels:
• Popup window for signaling important events, e.g. in the case
of alarm messages. Mandatory acknowledgment is selectable
for particularly important events
• Events list for clear representation of the individual events with
symbols indicating the alert level
• Detail window with particulars of the event, e.g. event class,
date and time of occurrence, reason for triggering the event
and, where applicable, the measurement variable in question
with its measured value and limit value
Event recording can be configured with the powerconfig
configuration software.
Plain-text displays
A large, fully graphic LCD display enables easy reading even
from great distances. To make sure that this is also the case in
poor light conditions, the backlighting can be individually
adapted to the actual requirements.
In addition to the standard displays of the 7KM PAC3100/3200,
the 7KM PAC4200 measuring device offers up to four user-
definable displays. These displays can be used for individual
arrangement of the desired measured variables and for their
representation as bar or digital displays.
Operation, also multilingual
Operation is quick to learn thanks to the intuitive user guidance
using the four function keys in conjunction with multilingual plain
text displays. The experienced operator can also use direct
navigation for quicker selection of the desired display menu.
Following languages can be selected: English, Chinese, French,
German, Italian, Portuguese, Russian, Spanish and Turkish.
The product documentation is also available in 9 languages.
Multifunctional digital inputs and outputs
The 7KM PAC3200 measuring device is equipped with one
digital input and output each, and the 7KM PAC3100 and
7KM PAC4200 measuring devices with two multifunctional
digital inputs and outputs, to each of which various functions can
be assigned.

Monitoring of measured variables for limit value violation
(7KM PAC3200 and 7KM PAC4200 only)
The 7KM PAC3200 has a function for monitoring up to
6 measured variables, and the 7KM PAC4200 up to
12 measured variables, for violation of an adjustable upper or
lower limit value.
The following variables can be monitored: Voltage, current,
power, power factors, THD for voltage and current, frequency,
unbalance of voltage and current.
In addition it is possible with the 7KM PAC4200 to monitor the
phase angle, distortion current strength, individual line harmon-
ics from the 3rd to the 31st harmonic, and sliding window
demand values.
The following can be assigned to each limit value:
• A measured variable
• The monitoring mode (overshooting or undershooting)
• A limit value
• A delay time and
• A hysteresis
It is possible to select the action to be triggered by violation of a
limit value.
For example, a signal can be sent through the digital output or
the communication interface. The integrated universal counter
can be used to total the number of limit value violations. Whether
a limit value has been violated is indicated on the device.
