Safety instructions
These operating instructions contain the information required for the proper usage of
the products described therein. They are addressed to technically qualified personnel,
who are specially trained or have otherwise obtained the relevant know-how in
instrumentation and control engineering (in the following referred to as automation
engineering). The knowledge and technically correct implementation of the safety
instructions and warnings contained in this manual are required for safe installation and
commissioning, as well as for safety during operation and maintenance of the described
product. Only qualified personnel as stipulated overleaf have the specialized knowledge
to interpret the general safety warnings and instructions of this documentation in every
specific case and to implement them in practice.
These operating instructions are an integral part of the scope of delivery. For reasons of
clarity, they do not include all details about all model of the product described, and also
cannot take into account every conceivable type of installation, operation and
maintenance. If you would like additional information, or if particular problems arise
which are not covered in sufficient detail in the documentation, please ask for the
necessary information from your local Siemens office, or contact the address on the back
page of the operating instructions directly.
Furthermore, it should be noted that this product documentation is neither part of a
previous or existing agreement, commitment, or legal relationship nor does it modify
such a relationship in any way. All Siemens obligations derive from the respective sales
contract, which also contains the complete and exclusive warranty agreement This

WARNING!
When electrical devices are operated, certain parts necessarily conduct dangerous
voltages. If the safety warnings are not heeded, severe injury or
damage can occur.
Only appropriately qualified persons are permitted to work on this equipment.
Appropriate transport, storage, mounting, and installation, as well as careful operation
and service, are essential for the error-free, safe and reliable opera
tion of this
equipment.
Modules and devices are tested with regard to their dielectric strength at 5.55kV/3.7 kV.
Devices with voltages up to a maximum of 500 V (to ground) in the measuring circuit
must demonstrate double isolation to the secondary circuit
s. Devices with voltages
higher than 500 V (to ground) in the measuring circuit must demonstrate basic isolation
against the secondary circuits. This must be observed during the installation
(section 10 Mounting and operation) and use of the devices.

Operating Instructions
1 Area of application
Transducers are used to convert different measured signals from high-voltage and low-
voltage systems into proportional output variables. In the power supply and distribution
industry, they are, for example, in areas where measured signals have to be transmitted
over large distances.
The passive SIMEAS transducers convert the alternating input voltage or the alternating
input current from the high-current power network (45 to 65 Hz) into a load-
independent direct output current.
Up to the maximum permissible load, multiple devices – recorders, indicators, remote
control systems, computers and controllers – can be serially connected and operated
directly or via long-distance lines to the output. The inputs and outputs are electrically
isolated. Auxiliary power supply is not needed.
The SIMEAS transducers must be installed in a closed system, such as a control cabinet.

4 Operating principle
The transformer (1) transfers the input signal IEor UEvia the rectification and filtering (2)
to the signal evaluation (3), which drives the output amplifier (4). Fed by smoothing, the
output amplifier provides a load-independent current IAproportional to the input value IE
or UE. The protective circuit (5) protects the output against no-load and transient
overvoltage.
With an alternating voltage transducer with expanded end range, the expansion circuit
(6) of the measuring range is adjusted

10 Mounting and operation
WARNING!
When electrical devices are operated, certain parts necessarily conduct dangerous
voltages. Failure to heed the operating notices can therefore lead to serious injury or
property damage.
The device should only be mounted and electrically connected by appropriately
qualified personnel. In particular, all warning notices must be observed.
10.1 Installation
•The installation location must be as free of vibrations as possible. The permissible
ambient temperature (operating or functional temperature) must be observed
(see technical specifications).
•Operation outside the functional temperature range can lead to erroneous
measurements and failure of the transducer.
•Plastic enclosure, overvoltage category III in accordance with DIN EN 61010 Part 1.
•Screw terminals for maximum 2.5 mm2or 4 mm2.
•The transducer must be mounted on a 35 mm DIN rail (in accordance with
DIN EN 50022). The DIN rail must be mounted horizontally.
10.2 Connection
The regulations for the construction of high voltage installations must be observed when
carrying out the electrical installation.
•If multiple receivers are used, for example recorders, displays, remote terminal
units, computers or controllers, these devices must be connected in series with
the current output of the transducer (ensure correct polarity). For transducers
with voltage output, the receivers are connected in parallel to this.
•The total load, including the cables, must not exceed the value stated in the
technical specifications.
•The pin assignment is shown in section 8 Description.
•The performed installation must be tested according to EN 61439.
Notes for the fuses to be used:
Appropriate protection must be provided for the measuring circuits during the
installation:
•Current measuring circuits: the fuse must prevent the values presented in the
table 6Technical specifications from being exceeded.
•Voltage measuring circuits: the fuse must limit the current to 100 mA,
be suitably arranged and be easily accessible to the user.
10.3 Installation material
Measuring circuits: The connection of the measuring circuit must be made with cables
that have demonstrated double isolation for the highest voltage occurring in the
measuring circuit.

SIMEAS-T - Transducer without auxiliary power
16
Secondary circuits: For devices in which the highest voltage of the measuring circuit is
500 V, cables with basic isolation in relation to the maximum voltage in each secondary
circuit suffice.
For devices with voltages that exceed 500 V in the measuring circuit, the isolation of the
cable in the secondary circuits must correspond to a basic isolation for the highest
voltage occurring in the measuring circuit.
11 Commissioning
First ensure that the operating data matches the values on the rating plate. No changes
may be made on the transducer. After a warm-up time of 15 minutes, the transducer is
ready for operation and keeps within the error limits.
•Measurement option for the output current and load voltage. Before connecting
an ammeter to the output side of the transducer, the primary side should be
switched off because the voltage at terminals 31 and 32 rises to a maximum of
30 V DC during the interruption of the output current IA .
•Measurement of the output current (output signal IA): Disconnect the line from
terminal 31(+) or 32(-), and connect the ammeter in series there.
•Measurement of the load voltage (output signal IA): Connect voltmeter to
terminals 31(+) and 32(-).
12 Maintenance
The output signal can be tested in a laboratory six months after commissioning and
subsequently every two years (section "Calibrating and testing"). The device has to be
opened for this. Apart from that, the transducer requires no maintenance.

13 Calibrating and testing
WARNING!
The work must be done in accordance with the specifications and performance
instructions of accident prevention regulation VBG 4.0. in particular 8. "Permissible
discrepancies while working on active parts". A suitable electrical tool must be used.
The transducer has to be opened for calibration.
