7.5 Adjusting the set pointers

The adjustment of the set points is

achieved using the adjustment lock

in the window with the aid of the

adjustment key (included in delivery).

Adjustment lock

Set pointer

The set pointers for the limit switches are freely adjustable over the full scale range. For

reasons of switching accuracy and service life of the mechanical measuring systems, the

switch points should be between 10 % and 90 % of the measuring range.
