2.1 Intended use
The models SC58 and SC64 are temperature controllers for simple
thermostat applications and are used, for example, in large-scale plant.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the instrument
outside of its technical specications requires the instrument to be taken
out of service immediately and inspected by an authorised WIKA service
engineer.
If the instrument is transported from a cold into a warm environment, the
formation of condensation may result in instrument malfunction. Before
putting it back into operation, wait for the instrument temperature and the
room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and
damage to equipment.
■
The activities described in these operating instructions
may only be carried out by skilled personnel who have the
qualications described below.
■
Keep unqualied personnel away from hazardous areas.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their
technical training, knowledge of measurement and control technology
and on their experience and knowledge of country-specic regulations,
current standards and directives, are capable of carrying out the work
described and independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g.
of aggressive media.

2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or
toxic gases or liquids, and refrigeration plants, compressors,
etc., in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
WARNING!
Protection from electrostatic discharge (ESD) required.
The proper use of grounded work surfaces and personal wrist
straps is required when working with exposed circuitry (printed
circuit boards), in order to prevent static discharge from
damaging sensitive electronic components.
To ensure safe working on the instrument, the operating
company must ensure
■
that suitable rst-aid equipment is available and aid is
provided whenever required.
■
that the operating personnel are regularly instructed in all
topics regarding work safety, rst aid and environmental
protection, and know the operating instructions, in
particular the section on safety instructions.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
■
The instrument may only be installed and mounted by
skilled personnel.
■
Operation using a defective power supply unit (e.g. short
circuit from the mains voltage to the output voltage) can
result in life-threatening voltages at the instrument!
WARNING!
Residual media in the dismounted instrument can result in a
risk to persons, the environment and equipment.
Take sucient precautionary measures.

4. Design and function
4.1 Description
These temperature controllers feature simple operation and a high switch
rating. In comparison to mechanical thermostats, these temperature
controllers can handle signicantly more switching cycles and thus have
a higher operating life.
The round design of the model SC64 enables it to be used as an
alternative to the purely-mechanical Combistat (model SC15).
The design of the model SC58 enables the controller to be used as
an alternative to the purely-mechanical remote-reading thermometer
(model TF58).
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
