Flying parts
If the battery is not secured correctly, it can be ejected in the case of
rotating machines.
Secure the battery using the knurled screws
Changes or modification to this device that have not been expressly
approved by FMS AG, will result in the FCC approval for operation of
this device being voided.
This device complies with the FCC Rules Part 15 as well as the RSS
standards issued in Canada not requiring approval. Operation is

subject to the following two conditions:
-The device may not cause any harmful interference, and
-This device must accept any interference received, including
interference that may cause undesired operation of the
device
Information about radio frequency radiation
This device complies with the FCC limit values for an uncontrolled
environment. This device should be installed and operated such that
a minimum distance of 20 cm is maintained between radiation
source and your body. This transmitter must not be operated near or
in connection with another antenna or transmitter
The function of this system is only ensured with the components in
the specified layout to one another. Otherwise, severe malfunctions
may occur. Thus, the installation information on the following pages
must be followed.
The local installation regulations ensure the safety of electrical
systems. They are not considered in these operating instructions.
However, they must be met.
Poor grounding can result in electric shocks for persons,
malfunctions of the overall system or damage to the control
electronics! Proper grounding must always be ensured.
It is of utmost importance to compensate for the centrifugal forces
generated through the rotation of the strander. Non-compensated
force-measuring rollers lead to faulty measurements.
Electrical connections must be implemented by an expert.
All system components are sensitive components that can be
damaged in the case of improper installation! Installation must be
performed by trained service personnel!

3Product Information
3.1 Functional Description
The telemetry system RTM X42 uses force sensors for measuring the wire tension of
strands and wires. It radio-transmits the measured values from the rotating to the static
part of the machine. The telemetry system RTM X42 with its components is an
integrated system. The individual components are optimally aligned to one another.
Thanks to its modular and space-saving design, it can be ideally used in confined
conditions of tubular type stranding machines, and cage type stranders with up to 42
spools. The machine efficiency is increased as well as the production yield during wire
and cable production.
3.2 System Extensions to the RTM X42 Measuring System

Control Software
-Clear presentation of measured values
-Storage, printing of measured data, quality documentation for your customers
-Integrated solution with user-friendly interface
-Storage of recipes, fast setup/conversion to other products
-Wide database for analysis, sound statements regarding system performance as
basis for process improvements
RTM X42.BC Brake control – Brake actuators on every spool carrier
-Integrated solution, fully automated control of the pull-off force
-For belt and rope type friction brakes, continuous production with highest quality
-Simple design, maintenance-free, robust, easy to retrofit, highest reliability
-Proven battery technology, ease of operation, long lifetime, highest efficiency

4Installation and Electrical Connections
4.1 Installation of Force Sensor for Core
Core measurement in static part of machine
The following information describes the installation of the core
sensor when installed outside the rotating part of the machine
The red point should be aligned in the direction of the resulting force. Further
installation information can be found in the installation manual of the force sensor.
Figure 2: Force sensor alignment in static area RTM_X42_Modbus_BA_Manual.ai
4.2 Installation of the Force Sensor in the Rotating Part of the Machine
In rotating applications, the force sensors are installed such that the centrifugal forces
are compensated.
Note
It is of utmost importance to compensate for the centrifugal forces
generated through the rotation of the strander. Non-compensated
force-measuring rollers lead to faulty measurements,
In the case of FMS force sensors of the RMGZ series, this is achieved by aligning the
force sensor such that the measuring direction is exactly parallel to the axis of rotation
of the strander. The red point of the force sensor points in the direction of the positive
force component.
Correct alignment of the red point can be tested after offset compensation and
calibration. If the display of an unloaded force sensor is always 0 N in all positions (e.g.,
in 12 o’clock or 6 o’clock position), the force measuring roller is aligned correctly.

RMGZ200_NEU_2017_BA_Manual.ai
Parallel alignment
The exact, parallel alignment of the measuring direction to the axis
of rotation of the machine is decisive for achieving precise measured
data.
Otherwise, measured value fluctuations occur during machine
operation due to the high sensitivity of the FMS force sensors. These
interfere with the assessment of the product quality later.
Due to irregularities in the installation surfaces, the alignment may have to be
readjusted very precisely. Some FMS force sensors feature an integrated mechanism
facilitating this fine adjustment. For force sensors without such features, we
recommend the use of shims or thin metal strips.
4.3 Installation of the Electronics Components in the Rotating Part of
the Machine
The transmitter module and the channel extension modules should be mounted as
closely as possible to the axis of rotation of the strander. This reduces the influencing
centrifugal forces.
During installation of the transmitter module, make sure that the centrifugal forces do
not act in the direction of the fastening screws of the battery.
Make also sure that the transmission path to the receiver module is free from obstacles.
Mount the receiver as high as possible.
