3.1

 

Assembly Conditions 

The Force Measuring Rollers RMGZ 400B and RMGZ 600B are 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 must be met: 

 
 

 

Caution 

The Measuring Rollers 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 Rollers 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

 

Assembly Preparations 

The Force Measuring Rollers RMGZ 400B and RMGZ600B are usually mounted 
on a mounting bracket which is in turn installed on the machine frame or on the 
rotating base plate of a stranding machine. The built-in flange on the force 
measuring roller provides M8 thread holes for easier assembly. If mounting 
brackets are used, they need to have mounting holes with a spline groove (see 
drawing Fig. 1, detail A). 

Mounting brackets and machine must be prepared for the installation of the 
force measuring rollers. The 

corresponding mounting holes must be drilled in the 

machine frame. 

 

 

Caution 

If the RMGZ 400B/600B Force Measuring Rollers are used as a replacement for 
their predecessor products RMGZ 400A/600A, the 4mm 0[.157“] position pin 
must be replaced with the supplied pin ø3x5 [0.118“ x 0.197“].
