Safety Information

2.1

Definition of notes and symbols

Danger !

This symbol signals an imminent danger to the life and
health of individuals.
If this note is not observed, injury to health and even most
serious injuries may be the consequence.

Warning !

This symbol signals a harmful situation.
If this note is not observed, the product may be damaged.

Note !

This symbol refers to proper handling of the product. It does not refer to
or indicate a dangerous situation.

2.2

Proper use

The I/H converter serves to transform an electric set signal
into a related hydraulic output pressure reduced to feed-in pressure. This
allows, for example, adjusting control pistons at hydraulic cylinders which
are used to position the valves of steam turbines.

2.3

Important notes

The following notes refer to the entire instruction manual and have to be
observed in addition to the individual notes.

Accident prevention

·

  Improper use may cause operating agent under pressure to leak

at the sealing surfaces. There is a risk of fire around hot components.

·

  Isolate the hydraulic supply prior to working on the I/H converter.
