1 Safety Instructions

All safety related regulations, local codes and instructions that appear in the manual
or on equipment must be observed to ensure personal safety and to prevent damage
to the equipment connected to it. If equipment is used in a manner not specified by
the manufacturer, the protection provided by the equipment may be impaired.
Do not stress the equipment over the specification limits neither during assembly nor
operation. To do so can be potentially harmful to persons or equipment in the event
of a fault to the equipment.

1.2 List of Safety Instructions

Changes or modifications made to this equipment not expressly approved by

(manufacturer name) may void the FCC authorization to operate this equipment.

This devise complies with Part 15 of the FCC Rules and with Industry Canada licence-

exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this devise may not cause harmful interference, and
(2) this device must accept any interference received, including interference

that may cause undesired operation.

Radiofrequency radiation exposure Information.

This equipment complies with FCC radiation exposure limits set forth for an

uncontrolled environment. This equipment should be installed and operated with
minimum distance of 20 cm between the radiator and your body: This transmitter
must not be co-located or operating in conjunction with any other antenna or
transmitter.

It is of paramount importance to compensate the centrifugal forces caused by the

rotating base plate of the stranding machine. The measuring results will be wrong, if
this rule is broken.

Proper function of the FMS RTM MP System can only be guaranteed with the

recommended application of the components. Other arrangements can cause
malfunctions. Therefore, the installation instructions on the following pages must be
followed.

Local installation regulations are to preserve safety of electric equipment. They are not

taken into consideration by this operating manual. However, they have to be followed
strictly.

The shield should be connected only to the electronic unit. On the force sensor side the

shield should stay open.

Bad earth ground connection may cause electric shock to persons, malfunction of the

total system or damage of the electronic unit! It is vital to ensure that proper earth
connection is done.

The sensor cables must be installed separate from power lines.

2 System Description

2.1 Functional Description RTM MP System

FMS’ RTM MP System has been developed to measure and evaluate all kind of
production relevant parameters in Wire Processing Machinery (especially in Bow Type
Stranding Machines). The System consists of a combined transmitter-decoding unit, a
receiver and further decoding modules in the receiver part. RTM MP uses two force
sensors for the measurement of the wire tension. Encoder signals and wire tension

06.03.2019 4

Operation Manual RTM MP Plus

values are captured, conditioned and sent over a 2.4 GHz wireless link to the receiver
unit EMGZ 48R.MP. Further processing of the encoder signals takes place in the
decoding module EMGZ443R.MP Here all relevant data for the actuator drivers or the
machine control is available. A fully equipped system can handle up to 16 digital
inputs and outputs, two force measuring rollers and 2 encoder channels. The later
can e.g. be used for close loop control of drives and the control of the traverse guide
in individual bobbins.

4 Installation and Wiring

4.1 Area of Machine Rotation

Following RTM MP components are installed either on the rotating part of the machine
or in the area of machine rotation:

● Transmitter EMGZ482T.MP.PLUS.W.24VDC

● RMGZ Force Measuring Rollers

4.2 Static installation of force sensor

Fig. 2: RMGZ Red Point alignment on static machine parts
RTM_X42_Red_Point_Allignment_BA_Manua.ai

The red point should always be aligned in the direction of the resulting Force (see Fig.

2). For further mounting information please consult the respective installation manual
of the sensor. The installation manual is always delivered together with the sensor.

4.3 Installation of Force Sensors on a Rotating Machine Part

Note

In rotating applications the force measuring sensors are mounted such that
centrifugal forces are compensated. If using FMS RMGZ sensors, this can be achieved
by turning the Red Point parallel to the rotation axis and in direction of the positive
force component (refer to Fig. 3).

Note

The adjustment of the red point can be tested after offset compensation and
calibration. If the reading of an unloaded load cell stays at zero regardless of the load
cell position (e.g. at 12 o’clock or at 6 o’clock position), the red point is correctly
aligned.

rotating base plate of the stranding machine. The measuring results will be wrong, if
this rule is broken.

4.4 Mounting and Wiring the Electronic Components

An RTM MP system is usually delivered complete with all its components and cables.
The cables are prepared with connectors on both sides for easy assembly

Caution

Proper function of the FMS RTM MP system can only be guaranteed with the
recommended application of the components. Other arrangements can cause
malfunctions. Therefore, the installation instructions on the following pages must be
followed.

Operation Manual RTM MP Plus

4.6 Wiring of the transmitter EMGZ482T.PLUS.MP.W.24VDC

One or two force sensors can be connected to the RTM-Transmitter. It is favourably to
mount the EMGZ482T.PLUS.MP.W.24VDC transmitter close to the RMGZ load cells to
keep the signal cables short.
If no standard FMS cables are used, the connection between force sensors and
transmitter must be wired with 2x2x0.25mm2 [AWG 23] shielded twisted-pair cable.

Caution

The shield should be connected only to the electronic unit. On the force sensor side
the shield should stay open.

Caution

Bad earth ground connection may cause electric shock to persons, malfunction of the
total system or damage of the electronic unit! It is vital to ensure that proper earth
connection is done.

Caution

The sensor cables must be installed separate from power lines.

4.7 Components on the Static Part of the Machine

Following RTM MP components are installed on the static part of the system:

● Receiver EMGZ482R.MP

software, a configured 2.4 GHz radio-link.

5.1 RTM MP Quick Start

1. After having mounted and wired the RTM MP system components on your
machine power up the transmitter EMGZ482T.MP and receiver EMGZ482R.MP

2. The RTM MP system will establish the wireless radio link automatically. This initial
process can take 5-10 sec.

3. After having achieved a stable radio link the LCD display on the EMGZ482.MP.R
will show:

4. The system is now ready and can be configured to over the operation panel on the

5.3 Offset Compensation Procedure

With the Offset Compensation one can compensate the roller weight of the sensor.
This procedure is always performed before the calibration. The force measuring roller
should not be loaded while the Offset Compensation is being done. The roller weight
compensation is performed for both channels (sensor 1 and sensor 2).
Procedure:

1. Remove any wires that may apply a force to the roller.

2. Close a contact between terminal 10 and 13 on the EMGZ482R.MP (see Fig. 6).
The switch time must be >100 ms.

3. This connection will perform the offset compensation on both force measuring
rollers (sensor 1 and 2).

Operation Manual RTM MP Plus

5.4 Calibration Methods

Fig. 12: Calibrating the measuring amplifier RTM_MP_BA_Manual.ai

The Calibrating procedure (setting the Gain), adjusts the controller and force sensors
so that the output gives you the actual tension value. There are two methods of
calibrating the system. The first method uses a defined weight. The second method is
based on a calculation method in conjunction with the FMS Calculator. This Calculator
can be down loaded from the FMS web page. FMS recommends using the method with
the weight (see Fig. 12) since it delivers the most accurate results.

5.5 Calibration Procedure

1. The calibration of the sensors must be performed with the PLC

2. Load a rope on the roller with the weight corresponding to your calibration force.
The roller configuration must correspond to the real material path in the machine
(wrap angle, distances between the rollers etc.).

3. The RTM MP-system will deliver tension raw data via the corresponding output

4. Enter the force data in your PLC and calibrate it matching your controlling needs.

5.6 Relay Output for Lost Communication

The relay output on the receiver EMGZ482.MP.R is deactivated, if the communication
link between receiver and transmitter is lost. For the technical specification of the
relay output see chapter 8“Technical Data”, Table EMGZ482R.MP.
