2.3 Destination and use
The AZM 161 AS is designed for use with AS-Interface Safety at Work.
The different variants of the component can be used as safety switch
with interlocking function or as solenoid interlock for position monitoring
and locking of moveable safety guards to EN 1088.
An AS-Interface Safety at Work component functions on the basis of an

mitted over the AS-i network and monitored by the ASM safety monitor.
The safety function of the AZM 161 AS consists in safely switching off
the code transmission when the safety guard is opened and maintaining
the safe switched off condition for as long as the safety guard is open.
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.
Interlocks with power to lock principle may only be used in
special cases after a thorough evaluation of the accident risk,
since the safety guard can be opened immediately on failure
of the power supply or upon activation of the main switch.
For an application requiring a safe linterlocking, the
AZM 161 Z ST-AS or the AZM 161 BZ ST-AS variant must
be selected. The AZM 161 B ST-AS is a safety switch with
additional interlocking function.
The user must evaluate and design the safety chain in ac-
cordance with the relevant standards and the required safety
level.

Manual release
A manual release is available as a mounting tool and in the event of a
power failure in case the power to unlock principle is used.
The manual release is realised by turning the triangular key by 180
degrees, so that the locking bolt is pulled into the unlocking position.
The normal locking function is only restored after the triangular key has
been returned to its original position. After being put into operation, the
manual release must be secured by installing the plastic cover, which is
included in delivery.

5.2 Magnet control
The control system with the AS-Interface Master can lock and unlock the
solenoid interlock through the output bit 0 of the addressed AS-i slave
AZM 161 AS. In the power to lock variant of the AZM 161 AS, the functio-
nal set of output bit 0 will cause the solenoid interlock to be locked. In the
power to unlock variant of the AZM 161 AS, the functional set of output bit
0 will cause the solenoid interlock to be unlocked.
5.3 Programming the slave address
The slave address is programmed through the M12 connector. Any
address from 1 to 31 can be set by means of the AS-i bus master or a
hand-held programming device.

5.5 Status signal "safety release"
The "safety release" status signal from a Safety at Work slave can be
cyclically queried by the control system through the AS-i master. To
that effect, the 4 input bits with the varying SaW code of a Safety at
Work slave are evaluated through an OR operation with 4 inputs in the
control system.
