Overview
Safety Solution local
With the Safety local modules
•
Safety local isolator module and
•
400 V disconnecting module
with an appropriate connection, safety level PL e
(according to ISO 13849-1) can be reached.

and High Feature starter mounted on a wide module rack
Safety local isolator module
The Safety local isolator module is a repair switch with integrated
safety evaluation functions that can be parameterized using
DIP switches.
It is used for
•
Connection of a 1 or 2-channel EMERGENCY-STOP circuit
up to PL e (protective door or EMERGENCY-STOP
pushbuttons) and parameterizable start behavior
•
For controlling the 400 V disconnecting module by means of a
safety rail signal
400 V disconnecting module
The 400 V disconnecting module enables the safe disconnec-
tion of an operational voltage of 400 V up to PL e. For operation
in a Safety Solution local application, it functions only in combi-
nation with the Safety local isolator module.
For operation in a Safety PROFIsafe application it functions only
in combination with the F-Switch.
Functionality
Safety local isolator module
The Safety local isolator module features the same functions as
a standard isolator module with an additional local safety
function.
The Safety local isolator module contains a 3TK2841 module
and is equipped with M12 terminals for the connection of
external safety components.
Terminals 1 and 2 can be used to connect either 1-channel or
2-channel EMERGENCY-STOP circuits or protective door
circuits (IN 1, IN 2).
For monitored starts, an external START switch can be
connected to terminal 3.
The required safety functions can be set using two slide
switches located under the left M12 opening.
In the event of an EMERGENCY-STOP, the Safety local isolator
module trips the downstream 400 V disconnecting module. This
safely separates the 400 V circuit up to PL e.
In combination with the 400 V disconnecting module, the
Safety local isolator module can be used for safety applications
up to PL e.
400 V disconnecting module
The 400 V disconnecting module can be used together with the
Safety local isolator module for local safety applications and to-
gether with the F-Switch for PROFIsafe safety applications.
It contains two contactors connected in series for safety-related
disconnection of the main circuit.
The auxiliary circuit supply of the device is over a safety power
rail in the backplane bus module.
The 400 V disconnecting module can be used in conjunction
with the Safety local isolator module or with the F-Switch for
safety applications up to PL e.
