Applicability
These operating and assembly instructions apply exclusively for the following measuring
system series with
incremental-interface
and
functional safety
:
·
FG 41
The measuring system stands out due to 2 variants which are distinguished in the chapter
“Main features” on page 7.
The products are labelled with affixed nameplates and are components of a system.
The following documentation therefore also applies:
·
operator’s operating instructions specific to the system
·
