1Safety 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.
1.1 Description Conditions
a) Danger of health injury or loss of life
Danger
This symbol refers to high risk for persons to get health injury or loss life. It has to
be followed strictly.
b) Risk of damage of machines
Caution
This symbol refers to information, that, if ignored, could cause heavy mechanical
damage. This warning has to be followed absolutely.
c) Note for proper function
Note
This symbol refers to an important information about proper use. If not followed,
malfunction can be the result.
The Force Measuring Sensors may not be stressed over the specification
limits neither during assembly nor operation. The unit’s overload protection value
may not be exceeded.
The attachment points for the Force Measuring Sensors on the machine
frame must be properly designed. The bearings need to be appropriately mounted.
In order to avoid ground loops and hence electrical interferences, cable shield
needs to be connected only to the measuring amplifier. On the force measuring side
the shield must stay open

3Assembly Preparations
3.1 Assembly Conditions
The Force Measuring Sensor RMGZ100A is defined as “partly completed machinery”
according to the Directives 2006/42/EC, article 2. In order to assure a proper
functionality of the parts and guarantee the essential health and safety requirements of
operators working with it, the following conditions for the assembly of RMGZ100A
must be met:
Caution
The Force Measuring Sensors may not be stressed over the specification limits
neither during assembly nor operation. The unit’s overload protection value may
not be exceeded.
Caution
The attachment points for the Force Measuring Sensors on the machine frame must
be properly designed. The bearings need to be appropriately mounted.
Caution
For correct installation and operation, follow the electrical wiring diagram and
instructions in this manual.

3.2 Mounting the Force Measuring Roller
The two flanged ball bearings SF626-2Z are removed from their seat and press-fitted
into the deflection pulley. Then the deflection pulley with the bearings is fitted to the
measuring roller and the circlip is mounted. The mounting bracket (ref. to fig. 1) is
part of the scope of delivery. It is mounted to the machine frame using two screws.
Tapped holes are required according to fig. 1. The position of the red point depends on
the application: If the force acts in the direction of the red point, positive values will
result from the measuring amplifier output.
3.3 Wiring
Connection between Force
Measuring Roller and measuring
amplifier is done by using
2x2x0.75mm2[AWG 18] shielded
twisted-pair cable. (With cable
length below 15m, 2x2x0.25 mm2
[AWG 23] is also suitable.) The
cable must be installed separate
from power lines.
The connection has to be done referring to fig. 2. The shield has to be connected only
to the measuring amplifier.

4Maintenance / Disassembly
4.1 Maintenance
All FMS Force Measuring Sensors are maintenance-free. Depending on the type of
bearing used, it may be necessary to periodically lubricate the bearings.
4.2 Disassembly
The disassembly of the Force Measuring Sensors is done by reversing the order of the
assembly procedure.
5Description of the Design
5.1 Functional Description
The Force Measuring Roller RMGZ100 series is used to measure the tension in wire,
cable, and similar materials. The Force Measuring Roller is equipped with two
lifetime lubricated deep groove ball bearings. The customer specific deflection pulley
is mounted to them. The Force Measuring Roller RMGZ100 series work according to
the principle of the bending test beam. Four foil-type strain gauges configured in a full
Wheatstone Bridge measure the bending and thus the material tension. Factory set
overload protection devices prevent deformation of the measuring web caused by
overload. The load must always be applied in the middle of the two bearings to ensure
reproducible measuring results.
