EN
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 when safety
switchgear is used. 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
resulting from such invasive work, arbitrary repairs, conversions and/or
modifications to the device.

the compliance with the Machinery Directive is maintained.
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 Comprehensive quality insurance to 2006/42/EC
Schmersal is a certified company to appendix X of the Machinery
Directive. As a result, Schmersal is entitled to autonomously conduct
the conformity assessment procedure for the products listed in
Appendix IV of the MD without involving a notified body. The prototype
test certificates are available upon request or can be downloaded from
the Internet at www.schmersal.com.
2.4 Destination and use
The AZM 200 with non-contact electronic safety sensors is designed for
application in safety circuits and is used for monitoring the position of
movable safety guards.
The safety function consists of safely switching off the safety outputs
when the safety guard is unlocked or opened and maintaining the safe
switched off condition of the safety outputs for as long as the safety
guard is open.
For applications requiring a safe monitoring of the interlocking
function, the AZM 200 ... variant must be selected. The AZM
200 B ... is a safety switch with additional interlocking function.
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.
The safety switchgears are classified according to
ISO 14119 as type 4 interlocking devices.
Series-wiring
Series-wiring can be set up. The response and risk times are 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. Up to 31 components can be wired in series.
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.
