Components required in relation to safety requirement

¹⁾ PM-D F3 power module only approved up to Category 3

²⁾ F kit required for Standard motor starter only; already integrated into High Feature motor starter

Possible combinations of safety and terminal modules

³⁾ For F1 or F2 in higher-level or individual safety group (potential group)

⁴⁾ For F1 or F2 in lower-level cascaded safety group (partial potential group)

⁵⁾ For expansion with F3 or F4 in separate ET 200S station (potential group)

⁶⁾ For expansion with F3 or F4 in the same ET 200S station (partial potential group)

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

In the case of safety applications with SIGUARD systems, the following safety modules are used individually or combined instead of the PM-D standard power module:

• PM-D F1 for evaluating emergency stop circuits with the function "Monitored start"
• PM-D F2 for monitoring of protective doors with the function "Automatic start"
• PM-D F3 as expansion for 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 (station)
• PM-D F5 for transmitting the status of PM-D F1...4 over four floating relay circuits to external safety devices (contact multipliers)

These serve as safety relays for downstream ET 200S motor starters.

The PM?D F1 and PM?D F2 safety modules can be combined with the PM?D F3 or PM?D F4 modules. A PM?D F5 can be arranged in any position between a PM-D F1...4 and a PM?X.

Every safety circuit starting with a PM?D F1 ... 4 must be terminated by a PM?X. An additional PM?D power module is not required.

The PM?D F1 ... F4 safety modules monitor the auxiliary voltages U₁ and U₂. A voltage failure is communicated in the form of a diagnostics message via bus.

Failsafe kit

Every standard motor starter in a safety segment has to be supplemented by the failsafe kit (F-kit) 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 comprise:

• Contact carriers for the terminal modules
• 1 or 2 auxiliary switch blocks for the contactor(s) of the motor starter
• Connecting lines

High Feature motor starters and their terminal modules come equipped with the F?Kit functions.

TM-PF30 terminal modules for PM-D F1 ... F5 safety modules

The TM-PF30 terminal modules are used to accommodate the PM-D F1 ... F5 safety modules (see table for possible combinations). Depending on the version, they are suitable for:

• Supply of 24 V DC for the electronics (U₁) and the contactors of the motor starters (U₂)
• Sensor connection: connection of 2-channel sensor circuit (e.g. emergency stop button) and a reset button
• Design of separate safety circuits
• Cascading of safety circuits

TM-X terminal module for PM-X safety module

The TM-X 15 S27-01 terminal module (TM-X) is a carrier for the PM-X safety module. It must be positioned on the right next to the last motor starter of a safety circuit.

The TM-X is suitable for connecting an external supply contactor (second switch-off possibility). It has terminals for connecting the contactor coil and the feedback contact.
