2.1 Application range
SIMEAS transducers for DC current or DC voltage with auxiliary power convert
the input current or the input voltage into load-independent DC output current or
load-independent DC output voltage. As long as the maximum permissible limit
is not exceeded, several appliances, such as recorders, indicators, telecontrol
systems, computers or closed-loop controllers, can be connected and operated
either directly or via remote connection. Input, output and the auxiliary power
supply are safely separated from one another.
2.2 Performance features
•
low price
•
small dimensions
•
short delivery times, standard types ex warehouse
•
immunity to electromagnetic interference
•
compliance with relevant national and international standards
•
high quality, long life
•
safe isolation with high test voltage
•
high measuring accuracy
•
powerful output signal circuits
•
high plant safety and reliability

2.3 Working principle
Via resistors (1), the input voltage U
E
is adapted to the pulse-pause-ratio voltage
converter (2). The rectangular signal generated by this is transmitted via a
transformer (3) to the output side, fi ltered and conditioned by the amplifi er
(4). The output amplifi er (5) supplies a load-independent direct current I
A
proportional to the input signal or a load-independent direct voltage U
A
. Zero
adjustment of the characteristic curve can be carried out with the reference
current I
const
.
The auxiliary power isolator (6) generates the galvanically isolated supply
voltage of the input circuit.
The auxiliary power U
H
~ or U
H
- is converted into the internal supply voltages via
an AC or DC voltage auxiliary power module (8).

2.6 General remarks
These operating instructions include the information required for appropriate
use of the products described therein. The document is addressed to technical
personnel with special qualifi cations or know-how in the fi eld of instrumentation
and control engineering, in the following referred to as automation
engineering.
Knowledge of and compliance with the safety notes and warnings described
in this manual are a basic requirement for safe installation, commissioning,
operation and maintenance of the product described. Only qualifi ed personnel,
as described below, have the required expert know-how to correctly interpret
and apply the general safety notes and warnings in each specifi c case.
These operating instructions are part of the scope of delivery. In order to preserve
the lucidity of the text, not all details of the various models have been included.
Similarly, it is not possible to describe all possible installation, operation and
maintenance procedures in this text. If further information is required or if
special problems occur which are not suffi ciently described in this document,
please request the specifi c information from your local Siemens offi ce or contact
one of the departments listed on the back cover of this manual.
Furthermore, it should be noted that the contents of this product documentation
are neither part of a previous or an existing agreement, commitment or legal
relationship nor do they affect such a relationship in any way. All Siemens
obligations derive from the respective sales contract, which also includes the
complete and exclusive warranty agreement. This warranty agreement is neither
extended nor restricted by any statements in this manual. The auxiliary power
supply of the units must be equipped with an interrupter, such as an automatic
circuit-breaker. This must be marked and installed in the vicinity of the units.
WARNING
Certain parts of electrical appliances are inevitably under hazardous voltage
during operation. Grievous physical injury or damage can occur if the safety
warnings are not heeded.
Only suitably qualifi ed personnel should service this appliance. Appropriate
transportation, storage, installation, assembly, operation and maintenance are
basic requirements for correct and safe operation of this appliance.
Units and appliances are tested with regard to their dielectric strength at 5.55
kV/3.7 kV; their output circuits, however, do not carry functional extra-low
voltages with safe separation according to VDE 0100, Part 410. This must be
taken into account when using these units and appliances.

2.10 Installation and operation
WARNING
Certain parts of electrical appliances are inevitably under hazardous voltage
during operation. Grievous physical injury or damage can occur if the operating
instructions are not heeded.
The installation and connection of the appliance must only be carried out by
suitably qualifi ed personnel.
In particular, all safety warnings must be observed.
Installation
•
The installation point should be as free from vibrations as possible. The
permissible ambient temperature (working or functional temperature) must
be observed (see Technical specifi cations).
•
Operation outside the functional temperature range can result in incorrect
measurement and may lead to a failure of the transducer.
•
Plastic housing, overvoltage category III according to DIN EN 61010 part 1.
•
S
crew terminals for max. 2.5 mm
²
or 4 mm
²
.
•
The transducer can be snapped onto a 35 mm top-hat rail (according to DIN
EN 50022).
•
The units are certifi ed only for operation in closed
housings or cubicles.
Connection
The regulations concerning the electrical installation of power systems must be
complied with.
•
If several receiving units, e.g. recorders, indicators, telecontrol systems,
computers or closed-loop controllers are to be used, they should be connected
in series with the current output of the transducer (pay attention to the
polarity!).
•
The auxiliary power connection must be protected externally.
•
The entire load, including the wiring, must not exceed the maximum value
given in the technical specifi cations.
•
The terminal assignment is described in section 2.9.

2.11 Startup
Make sure that the operating data match the data given on the rating plate.
Do not modify any transducer settings. The transducer is operational after a 15
minute warm-up period and will keep within the error tolerances.
•
Measuring the output current and the load voltage:
Before connecting an amperemeter to the output side of the transducer,
the auxiliary power must be disconnected, since the voltage at terminals 31
und 32 can reach a maximum of 30 V DC during interruption of the output
current I
A
.
•
Measuring the output current (output signal I
A
):
Disconnect the wire from terminal 31(+) or 32(-) and connect the amperemeter
in series.
•
Measuring the load voltage (output signal I
A
), or the output signal U
A
:
Connect the voltmeter to terminals 31(+) and 32(-)
2.12 Maintenance
The transducer is maintenance-free. The output signal can be tested in a
laboratory 6 months after startup and thereafter every two years (section on
“
Calibration and testing
“
). For this, the appliance needs to be opened.

2.13 Calibration and testing
WARNING
When carrying out these tasks, the provisions and instructions of the accident
prevention regulations VBG 4.0 must be observed. Point 8 is of particular
importance:
“
Permissible deviations while working on active parts
“
. Appropriate
electrical tools are to be used.
To calibrate the device, the transducer needs to be opened and the subassembly
units removed.
After disconnecting the external wiring, open the lid of the transducer and
remove the subassembly units. The circuit comprises the following units:
–
measuring module G34924-J1003-L1
–
connection module G34932-F1801-L1
–
power supply unit G34932-F1802-L1
The trimming potentiometers are on the measuring module.
Special care is required during work on the open modules, since hazardous
voltages could be present on the back of the measuring module and power
supply unit.
Therefore, the back of the modules should be appropriately covered.
