SIMATIC ET 200S26
Motor starters for any application
The ET 200S motor starters can be used to protect and
switch any three-phase load. The completely prewired
devices are available in different performance classes as
direct, reversing or soft-starters up to an output of 7.5 kW.
The terminal module contains the self-assembling energy bus
and the terminals for direct connection of the motor cable. A
motor starter can be removed and inserted without the need
to isolate the system.
Standard motor starters
• Circuit-breaker and contactor combination up to 5.5 kW
• Direct-on-line or reversing starters
• Optional safety system
• PCS7 faceplates for visualizing diagnostics data
High Feature motor starters
• Combination of starter circuit-breaker, electronic overload
protection and contactor or soft starter up to 7.5 kW
• PROFIenergy functionality for selective shutdown of mo-
tors during breaks, and reading out the motor current
• PCS7 faceplates for visualizing diagnostics data
• Statistical data, e.g. current for the last overload trip, can
be read out using the service and commissioning software
Motorstarter ES
• Parameterization via bus, and sending and receiving of acy-
clic data via the fieldbus
• Only two current setting ranges up to 7.5 kW
• Safety technology integrated
Fail-safe motor starter
As soon as more complex or widely distributed safety applica-
tions are implemented, the Failsafe motor starter in combina-
tion with the PM-D F PROFIsafe power module is the optimized
solution. Signals from safe sensors are read in through safe in-
puts at any required point in a plant and transferred to the fail-
safe controller via PROFIBUS by means of the PROFIsafe mes-
sage frame. In the application program they are linked to the
Failsafe motor starters or the associated power module.
The failsafe motor starter has been developed on the basis of
the High Feature motor starter. It offers the following innova-
tive, patented technology:
In normal operation, the contactor shuts down the circuit
breaker; in the event of a fault, this is handled by the integral
dual-processor monitoring. This makes shutdown possible
even if a contactor has a welded contact. It also ensures that
each individual motor starter achieves SIL 3 or Category 4
without additional redundancy contactors.
The fail-safe motor starter
monitors the function of the
contactor regardless of
whether the application is
safety-related or not, so
these devices are also suit-
able for use in high-availabil-
ity processes.
Further characteristics that
support high availability are:
• Type of coordination 2
over the complete power range up to 7.5 kW
• The emergency start function allows important processes
to be continued to completion despite a reason for shut-
down, e.g. overload.
Advantages of fail-safe motor starters
over conventional safety systems
• Significantly fewer components, therefore less complex
configurations and considerably less HW engineering and
wiring overhead
• Rapid installation thanks to simple plug-in technology
• Motor starters are fault tolerant and failsafe
• High degree of flexibility thanks to assignment to switch-
off groups in software
• When the safety application changes, there is
less overhead because the wiring is retained
Two alternatives are available:
Solution local
• Used for locally restricted safety applications
• For group deactivation of Standard, High-Feature or Fail-
safe motor starters without complex wiring for conven-
tional safety systems
• For local evaluation of EMERGENCY STOP circuits with
automatic or monitored starting
• Cascading of the shutdown groups
• Can also be used in combination with external safety cir-
cuits
Solution PROFIsafe
• For usage with safety-related applications that are com-
plex and interconnected
• The logic of the safety functions (safe sensors can be
freely assigned to Failsafe motor starters) is implemented
with software and thanks to safety-related communica-
tion (PROFIsafe)
• Safety module PM-DF PROFIsafe forms 6 shutdown
groups
• Selective and autonomous shutdown of the fail-safe mo-
tor starter for any safety function
• Also for infeed to external safety systems through F-CM
contact multiplier
