2.2 Special versions
For special versions, which are not listed in the order code below 21,
these specifications apply accordingly, provided that they correspond to
the standard version
2.3 Destination and use
The emergency stop switch meets the requirements of EN ISO 13850,
IEC/EN 60947-5-1 and IEC/EN 60947-5-5 Pull-wire emergency stop
switches are used on machinery and plants, where triggering the emer-
gency stop command must be enabled at arbitrary points on the wire run
If the tensioned pull-wire is pulled or in case of wire breakage, the
switching function of the pull-wire emergency stop switch is activated
(refer to image 1)

Design/operating principle
The pull-wire emergency stop switches are brought into the operational
condition by the proper pre-tensioning of a maximum 10 m long wire
The inner switching elements have 2 contacts; in tensioned condition,
the NC contacts are closed
After actuation of the switching function, a latching mechanism main-
tains the stop command until the switch is released by pushing the blue
reset button Prior to the reset of the stop signal, the reason why the
switch has been actuated must be determined The switch can only
be reset if the switch is correctly pre-tensioned (position indication in
central position, refer to image 1)
An AS-Interface Safety at Work component functions on the basis of an
individual code generator (8 × 4 bit) This safety code is cyclically trans-
mitted over the AS-i network and monitored by the ASM safety monitor
The component status can be evaluated through a PLC with AS-Inter-
face master The safety-related functions are enabled by means of the
AS-i safety monitor
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level
