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. Areas of application are, for
example
Power supply and distribution for areas in which measured signals must be sent over
a large
distance. The active SIMEAS transducers convert the alternating input voltage or the
alternating input current from the high-current power network (45 to 65Hz) into a
load-independent direct output current or a load-independent direct output voltage.
Up to the maximum permissible load, multiple devices – such as recorders, displays,
remote control systems, computers and controllers – can be connected and operated
directly or via long-distance lines at the output. Input and output with auxiliary power
supply are electrically isolated from each other.
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 IE or UE to the effective value
Direct voltage converter (2) which drives the output amplifier (4) via the expansion
circuit (3). Fed by the auxiliary source (6), the output amplifier provides load-
independent current IA or load-independent voltage UAproportional to the input
value IE or UA . The protective circuit (5) protects the output against no-load and
transient overvoltage.

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
•Before installing the device, check for external damage. In case of damage, the
device may not be installed, connected and operated.
•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.
•A switch or circuit breaker must be installed in the building installation, this
must be suitably arranged and easily accessible for the user and labeled as the
disconnecting mechanism for the device. This disconnecting mechanism has
to meet the requirements of IEC 60947-1 and IEC 60947-3.
•The total load, including the cables, must not exceed the value stated in the
technical specifications.
•The pin assignment is shown in the section 8 Description.
•The performed installation must be tested according to EN 61439.

SIMEAS-T - Transducer with auxiliary power
18
Notes for the fuses to be used:
For devices that are supplied with AC auxiliary energy, a 100 mA time-lag fuse
according to IEC 60127-2 must be connected upstream in the control cabinet
installation.
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 6 Technical 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.
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 auxiliary
power 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), or the output signal UA:
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.
WARNING!
The device contains no fuses to be changed by the user.

SIMEAS-T - Transducer with auxiliary power

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 and the modules removed for calibration. After
disconnecting the external electrical power cables, the enclosure cover is removed
and the modules pulled out. The circuit from the following modules:
•Measuring module G34932-F1800-H2
•Connection module G34932-F1801-H2
•Power supply module G34932-F1802-H2
The trim potentiometers are located on the measuring module.
Greater care is required when working on open modules because there may be
dangerous voltages on the rear of the measuring and power supply modules.
The rear sides of the modules should therefore be covered by suitable means.
