2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
The AZM 161 AS is designed for use with AS-Interface Safety at Work.
The safety switchgears are classified according to
ISO 14119 as type 2 interlocking devices.
The different variants can be used as safety switch with interlocking
function either as solenoid interlock for the position monitoring and
locking of movable safety guards.
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.
If the risk analysis indicates the use of a monitored interlock
then a variant with the monitored interlock is to be used,
labelled with the symbol.
The actuator monitoring variant (B) is a safety switch with an
interlock function for process protection.
The safety function of the safety switchgear consists of 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.
An AS-Interface Safety at Work component functions on the basis of
an individual code generator (8 x 4 bit). This safety code is cyclically
transmitted over the AS-i network and monitored by the safety monitor.
The component status can be evaluated through a PLC with
AS-Interface master. The safety-related functions are enabled by
means of the AS-i safety monitor.
LED display
The LED's have the following meaning (to EN 62026-2):
Yellow LED:
Channel 1 / AS-i SaW bit 0,1
LED green/red
AS-i duo LED:
AS-Interface supply voltage/
AS-Interface communication error or
slave address
=
0 or periphery error
Yellow LED:
Channel 2 / AS-i SaW bit 2,3
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°,
so that the locking bolt is pulled into the unlocking position. Please
ensure that jamming by external influence on the actuator is avoided.
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.
Triangular key TK-M5 (101100887) available as accessory.
