ETВ 200S Safety Motor Starter Solution local

Interplay of ET 200S safety motor starters Solutions local components

Components for Safety Motor Starter ET 200S Solution local

ETВ 200S Safety Motor Starter Solutions local comprise:

Version 1 (see example 1):

• Safety modules PMD F1 ... 5
• PM-X module
• Standard motor starter or High Feature motor starter

Version 2 (see example 2):

• PM-D FX1 safety module
• Failsafe motor starters

Functionality of the ETВ 200S Safety Motor Starter Solution local

• For using Standard, High Feature or Failsafe motor starters in systems with safety category SIL 1 (according to IEC 62061) or PL c to Pl e (according to ISO 13849-1)
• Can also be used in combination with external safety relays
• Can also be used to activate external safety systems
• No complex wiring for conventional safety technology
• Safety module available for function-monitored and automatic starting
• Safety module available for Stop category 0 and 1
• Safety module for monitoring the auxiliary voltages for motor starters
• Safety modules can be plugged into the TM-PF30 terminal modules

With Safety Motor Starters Solutions local the highest safety category can be reached according to ISO 13849-1 and IEC 62061. They can thus be used for evaluation of EMERGENCY-STOP circuits or for monitoring protective doors and also for time-delayed disconnections. With the contact multiplier the safety-relevant signals can also be made available to external systems.

All standard safety applications can be covered through combination of different TM-PF30 terminal modules. Needless to say, ET 200S motor starters can also be used in conjunction with external safety relays or with ASIsafe.

With the Safety Motor Starter Solutions local, up to 80 % of wiring is saved compared to conventional safety systems with local safety applications.

With the Safety Motor Starters Solutions local it is easy to configure several safety circuits. The safety sensors are connected directly and locally to the safety modules. These safety modules perform the work of the otherwise obligatory safety relays and safely shut down the downstream motor starters in accordance with the function selected. The crosslinks required for this are already integrated in the system and need no additional wiring. All signals from the safety modules are automatically relayed as diagnostic signals, e. g. in the event of crossover in the EMERGENCY-STOP circuit.

The safety module evaluates the signal state of the connected safety sensors and, using the integrated safety relays, shuts down the group(s) of downstream motor starters. The shutdown function is monitored by the module, and the auxiliary voltages likewise.

Safety-relevant system signals, e. g. due to an actuated EMERGENCY-STOP switch or a missing auxiliary voltage, are automatically generated and notified to the interface module. The latter assigns an unambiguous ID to the fault. Using the PROFIBUS DP diagnostics block, faults of this type can be identified and localized without a great deal of programming work.

PM-D F1/F2/F3/F4/F5 safety modules

• PM-D F1/F2/F3/F4 safety modules monitor auxiliary voltages and contain the complete functionality of a safety relay:
  • PM-D F1 For evaluation of EMERGENCY-STOP circuits with the function "Monitored start"
  • PM-D F2 For monitoring of protective doors with the function "automatic start".
  • PM-D F3 Expansion to PM-D F1/F2 for time-delayed tripping.
  • PM-D F4 For expanding safety circuits with other ET 200S motor starters, e. g. in a different tier
  • PM-D F5 Transmits the status from PM-D F1 ... 4 through four floating enabling circuits to external safety devices (contact multipliers)
• The PM-DВ F1 and PM-DВ F2 modules can be combined with the PM-DВ F3 or PM-DВ F4 modules.
• A PM-DВ F5 can be positioned at any point between a PM-DВ F1В ...В 4 and a PM-X¹⁾.
• Safety modules monitor the U1 and U2 auxiliary voltages. A voltage failure is relayed as a diagnostic signal over the bus.
  • No additional PM-D safety module is required when the safety modules are used.
  • Each safety circuit, beginning with a PM-D F1 ... 4, must be terminated with one PM-X each¹⁾.

PM-D F1 safety module

PM-D FX1 safety module

The PM-DВ FX1 safety module is used for feeding in one to six switch-off groups. The infeed voltage can be switched using one to six external safety shutdown devices (either ASIsafe monitors or 3TK28 safety relays). This safety module is used in applications with external safety shutdown devices where there is a need for the fully selective safety shutdown of failsafe motor starters/frequency converters (see exampleВ 2).

Terminal modules for (TM-PF30) safety module

For supplying load and sensor voltage to the potential bars of the motor starters, and for connection of the 2-channel sensor circuit (e. g. EMERGENCY-STOP pushbutton) and a reset button. Different terminal modules are available for the configuring of separate safety circuits or for the cascading of safety circuits, and for applications with time-delayed disconnection.

Terminal module (TM-X)

For connection of an external infeed contactor (2nd shutdown possibility), with terminals for contactor coil and feedback contact, is always required to terminate a group of safety-oriented motor starters.

Failsafe Kit

The Failsafe Kit (F-Kit) must be added to each Standard motor starter in a safety segment in order to monitor the switching function.

F-Kit 1 supplements the DS1-x direct-on-line starter, F-Kit 2 the RS1-x reversing starter.

The F-Kits are comprised of:

• Contact supports for the terminal modules
• One or two auxiliary switch blocks for the contactor/contactors of the motor starter
• Connecting cables

High Feature motor starters and their terminal modules come as standard with the functionality of the F-Kits integrated.

Examples

The diverse possible uses of the safety motor starter Solutions local are presented in the manual SIMATIC ET 200S Motor Starters in the context of typical sample applications.

Safety functional examples for easy, quick and low-cost implementations of applications with Safety Motor Starter Solutions local are also available online.

Example 1:

ETВ 200S Safety Motor Starter Solutions local withВ two safety circuits (= switch-off groups), Standard motor starters and High Feature motor starters.

Example 2:

ETВ 200S Safety Motor Starter Solutions local with two external safety combinations (= safety relays or ASIsafe monitors) and with Failsafe motor starters (PM-DFX1 application). Two of the six available safe switch-off groups are used.

Signals with relevance for safety can be input to ET 200S through a PM-DFX1 infeed terminal module through the enabling circuits of the ASIsafe monitor or the safety relay to control the Failsafe motor starters which then selectively switch off the downstream motors.
