A.1

Measured variables

Measured variables of the SENTRON PAC Power Monitoring Device
Availability via the communication interfaces
SENTRON PAC4200 provides the measured variables listed below via the communication
interfaces.
Information on the display
SENTRON PAC4200 shows most, though not all, measured variables on the display. The
"Display" column in the tables below shows the number of the screen on which the
measured variable is displayed. All measured variables that are not displayed are identified
by a hyphen ("-").
Short codes for monitored measured variables
The "LIM SOURCE" column in the tables below lists the measured variables for which limit
monitoring is possible. It contains the short codes that are used in the "SOURCE" field of the
"ADVANCED " > "LIMITS" > "LIM (0 to 11)" display.
Instantaneous values with maximum and minimum values
Name
Voltage a-n
Instantaneous value of the voltage between phase conductor a and the neutral conductor
Maximum voltage a-n

Minimum voltage a-n
Minimum value of the voltage between phase conductor a and the neutral conductor
Voltage b-n
Instantaneous value of the voltage between phase conductor b and the neutral conductor
Maximum voltage b-n
Maximum value of the voltage between phase conductor b and the neutral conductor
Minimum voltage b-n
Minimum value of the voltage between phase conductor b and the neutral conductor
Voltage c-n
Instantaneous value of the voltage between phase conductor c and the neutral conductor
Maximum voltage c-n
Maximum value of the voltage between phase conductor c and the neutral conductor
