P11, measuring instrument for line values with PROFIBUS
connection (installed in the cabinet door)
Availability of option
This option is available for the following S120 Cabinet Modules:
● Basic Line Connection Modules
● Active Line Connection Modules
Description
A measuring instrument "SENTRON PAC3200" with display, installed in the cabinet door of
the Line Connection Module, acquires measured values of the power supply. In addition to
these measured values, additional plant values (such as power and power factor, etc.) are
calculated from the measured values using powerful, state-of-the-art microprocessors. The
measuring instrument has a PROFIBUS interface that enables a transmission rate of up to
12 Mbit/s.
The device can measure the following as standard:
● Actual currents per phase and actual currents of the neutral conductor.
● Average currents and maximum currents over programmable time intervals from 1 to 60
min.
● Phase-to-neutral voltages and phase-to-phase voltages.
● Frequency (Hz)
● Four-quadrant measurement of the actual, average, and maximum active power (+/-),
reactive power (+/-) and apparent power (+/-) per phase and in total over programmable
time intervals from 1 to 60 min.
● Display of active energy in kWh.
● Power factor (PF) per phase and in total with the specifications "L" for inductive and "C"
for capacitive.
Note
Current transformers are required in the Line Connection Module to measure line currents.
Option L41 (current transformer upstream of the main switch) is included in option P11. The
measuring instrument "SENTRON PAC3200" is wired according to connection type 3P3W in
the factory.
The current transformers must not be operated unloaded.
Note
Additional information
Detailed and comprehensive instructions and information regarding the "SENTRON
PAC3200" measuring instrument can be found in the accompanying operating instructions.
These operating instructions are available as additional documentation on the customer DVD
supplied with the device.
