The information contained in this operating instructions manual is
provided without liability and is subject to technical modifications.
There are no residual risks, provided that the safety instructions as well
as the instructions regarding mounting, commissioning, operation and
maintenance are observed.
1.6 Warning about misuse
In case of improper use or manipulation of the safety
switchgear, personal hazards or damages to machinery
or plant components cannot be excluded. The relevant
requirements of the standard ISO 14119 must be observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this operating instructions
manual. The manufacturer shall accept no liability for damages
resulting from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary
repairs, conversions and modifications to the device are strictly
forbidden, the manufacturer shall accept no liability for damages

2.4 Purpose
The non-contact, electronic safety switchgear is designed for
application in safety circuits and is used for monitoring the position and
locking of movable safety guards.
The safety switchgears are classified according to ISO 14119
as type 4 interlocking devices. Designs with individual coding
are classified as highly coded.
The different variants can be used as safety switch with interlocking
function either as solenoid interlock.
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 consists of safely switching off the safety outputs
when the safety guard is opened and maintaining the safe switched off
condition of the safety outputs for as long as the safety guard is open.
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.
Series-wiring
Series-wiring can be set up. The risk time is not altered by wiring in
series. The number of components is only limited by the external cable
protection according to the technical data and the line loss. Series-
wiring of up to 31 AZM201…-SD components with serial diagnostics
is possible. In devices with the serial diagnostics function (ordering
suffix -SD), the serial diagnostics connections are wired in series and
connected to a SD Gateway for evaluation purposes. Wiring examples
for series-wiring, refer to appendix.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level. If multiple safety switchgears are involved in
the same safety function, the PFH values of the individual
components must be added.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
