2.2
Proper use
The I/H converter is provided to convert an electric set signal, e.g. 4 - 20 mA, to the
corresponding hydraulic output pressure reduced to the supply pressure. This allows, for
example, remote-controlled, infinitely variable adjustment of control pistons on hydraulic
cylinders positioning valves of steam turbines.
The permissible temperature of the hydraulic oil is +10 °C … +60 °C.
The max. surface of the device is significantly determined by the temperature of the
hydraulic oil.
For the operation it is therefore vital to ensure that the max. permissible oil temperature
will not be exceeded!
2.3
Important information
The following information refers to the entire instruction manual and is to be observed in
addition to the individual instructions.
Accident prevention
It is imperative to observe the requirements of the relevant standards and regulations
when connecting an I/H converter in explosion-proof design.
There must not be any potentially explosive atmosphere during all works performed,
such as e.g. transportation, storage, installation, electrical connection, commissioning,
test run, maintenance and servicing!
Operating medium leaving/leaking from the I/H converter may get in contact with hot
machine parts, posing a risk of fire.
When working on the I/H converter, it is vital to wear protective clothing.
On commissioning or operation of the I/H converter, spraying hydraulic oil may get into
the eyes causing blindness. Wear protective glasses for all works performed on the I/H
converter.
