Advantages through energy efficiency
Energy management in industry
Overview of the energy management process
We offer you a unique portfolio for industrial energy manage-
ment in the industry – a process that is used to optimize the
energy requirements. We divide operational energy manage-
ment into the three phases: identification, evaluation and imple-
mentation, and support you with suitable hardware and software
solutions in each phase of the process.
The innovative products of the SIRIUS industrial controls port-
folio can also make a substantial contribution to a plant's energy
efficiency
(see www.siemens.com/sirius/energysaving)
.
SIRIUS ACT pushbuttons and indicator lights contribute to
energy efficiency throughout the plant as follows:
•
Lower power consumption by means of LED technology
•
Long service life

Application
Environmental conditions
The pushbuttons and indicator lights are climate-proof (KTW 24)
and suitable for standard industrial applications and operation in
marine applications.
Safety EMERGENCY STOP pushbuttons according to
ISO 13850
For controls according to IEC 60204-1 or EN 60204-1, the
SIRIUS ACT mushroom pushbuttons are suitable for use as
safety EMERGENCY STOP pushbuttons.
Safety circuits
IEC 60947-5-1 and EN 60947-5-1 require positive opening. This
means that for the purpose of personal safety, the reliable open-
ing of NC contacts in all safety circuits is expressly prescribed
for the electrical equipment of machines and is designated ac-
cording to IEC 60947-5-1 with the symbol (
).
Category 4 according to EN ISO 13849-1 can be attained with
the EMERGENCY STOP mushroom pushbuttons if the corre-
sponding fail-safe evaluation units are selected and correctly
installed, e.g. the 3SK11 safety relays or the 3RK3 Modular
Safety System
(see page 11/1 onwards)
or matching units from
the ASIsafe, SIMATIC or SINUMERIK product ranges.
The SIRIUS ACT pushbuttons and indicator lights can be
connected to the AS-Interface communication system quickly
and safely.
The following solutions are available:
•
AS-Interface modules
•
AS-Interface module in safety-related version for
EMERGENCY STOP mushroom pushbutton
•
Ready-fitted AS-Interface enclosures with 1 to 6 command
points
IO-Link
The SIRIUS ACT pushbuttons and indicator lights can be
connected to IO-Link quickly and safely. The connection is made
via a special IO-Link-module.
