Safety notes

Siemens offers products and solutions with industrial security functions that support the

secure operation of plants, systems, machines, and networks.

In order to protect plants, systems, machines and networks against cyber threats, it is

necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial

security concept. Siemens’ products and solutions only form one element of such a concept.

The customer is responsible for preventing unauthorized access to its plants, systems,

machines and networks. Systems, machines and components should only be connected to

the enterprise network or the Internet if necessary and only to the extent necessary and with

appropriate protective measures (e.g. use of firewalls and network segmentation) in place.

Additionally, Siemens' guidelines on appropriate security measures should be observed. For

more information about industrial security, please visit

http://www.siemens.com/industrialsecurity.

Siemens’ products and solutions undergo continuous development to make them more

secure. Siemens strongly recommends applying product updates as soon as they are

available and always using the latest product versions. Using versions that are obsolete or

are no longer supported can increase the risk of cyber threats.

To stay informed about product updates, subscribe to the Siemens Industrial Security RSS

Feed at

http://www.siemens.com/industrialsecurity.

Note

Several protective mechanisms can be activated in the device.

In order to reduce the risk of manipulation occurring on devices, it is recommended that the

protective mechanisms available in the device are activated. See section "Security

(Page 11)".

Description

3.1 Features

The PAC3200T is a measuring device for measuring the basic electrical variables in low-

voltage power distribution. The device is capable of single-phase, two-phase, or three-phase

measurement and can be used in three- or four-wire TN, TT and IT networks.

The PAC3200T is mounted on a DIN rail.

Thanks to its large measuring voltage range, the PAC3200T measuring device can be

connected directly in any low-voltage system up to a rated voltage UL-L 480 V. X / 1 A and

x / 5 A current transformers can be used for current measuring. The integrated Ethernet

interface can be used for communication.

Measurement

● Measurement of all relevant electrical variables in an AC system.

Counters and power demand

● A number of energy counters record active, reactive and apparent energy.

● Calculation and storage of the last measuring period demand for active power and

reactive power for simple generation of load profiles using software (programmable

measurement period of between 1 and 60 min.).

Display and operator control

● LEDs for Ethernet, active energy, Power ON/OFF and overvoltage.

Manual, 04/2017, L1V30415168B-01

3.2 Measuring inputs

Current measurement

NOTICE

AC current measurement only

The device is not suitable for measuring DC current.

PAC3200T is designed for:

● Measuring current of 5 A for connecting standard current transformers. Each current

measuring input can take a continuous load of 10 A. A momentary overcurrent of up to

100 A and a duration of 1 s is possible.

The SENTRON powerconfig configuration software enables the current direction to be

changed individually for each phase. It is not necessary to change the terminal connections

of the current transformers in the event of connection errors.

Voltage measurement

NOTICE

AC voltage measurement only

The device is not suitable for measuring DC voltage.

PAC3200T is designed for:

● Direct measurement on the system or using voltage transformers. External voltage

transformers are required to measure higher voltages than the permissible rated input

voltages.

● Measurement voltage up to 277 V / 480 V. The device is designed for measuring input

voltages up to 277 V to the neutral conductor and for measuring input voltages up to

480 V to the external conductor.

Description

Short code Connection type

3P4W (factory setting) 3 phases, 4 conductors, unbalanced load

3P3W 3 phases, 3 conductors, unbalanced load

3P4WB 3 phases, 4 conductors, balanced load

3P3WB 3 phases, 3 conductors, balanced load

1P2W 1 phase, 2 conductors, unbalanced load

The input circuit of the device must correspond to one of the connection types listed. Select

the suitable connection type for the purpose.

You can find connection examples in the chapter "Connection".

NOTICE

The wrong system connection can destroy the device

Before connecting the PAC3200T, you must ensure that the local power supply conditions

agree with the specifications on the type plate.

The short code of the connection type must be entered in the device settings at startup. You

can find the instructions for parameterizing the connection type in the chapter

"Commissioning".

3.3 Power demands and counters

3.3.1 Acquisition of power demand

Values that can be read out

PAC3200T supplies the power demand of the last completed measuring period:

● Mean values for active power and reactive power, separated in each case for import and

export

● Minimum and maximum active power and reactive power

● Length of the demand period in seconds. The period may be shorter for reasons of

external synchronization.

● Time in seconds since the last synchronization or since completion of the last period.

Example: Period length and length of the demand period

Period length: 15 minutes; time of day: 13:03; time in seconds: 180 s.

The following can be calculated from this: The last demand period ended at 13:00. The

active demand period will end at 13:15 or in 12 minutes.

Availability

Note

The power demand of the last measuring period can only be fetched during the current

measuring period.

Adjustable parameters

● Time interval in minutes: 1 to 60 min adjustable, default 15 min
