3 Safety
3.1 Intended use
The expansion module monitors standstill, speed and direction of rotation in accordance
with EN ISO 13849-1 up to PL e and EN IEC 62061 up to SIL CL 3.
The expansion module may only be connected to a base unit from the PNOZmulti system
(please refer to the document "PNOZmulti System Expansion" for details of the base units
that can be connected).
The configurable small control systems PNOZmulti are used for the safety-related interrup-
tion of safety circuits and are designed for use in:
}E-STOP equipment
}Safety circuits in accordance with VDE0113 Part 1 and EN60204-1
WARNING!
Users must take appropriate measures to detect or exclude errors (e.g. slip-
page or broken shearpin) which cause the frequency of the encoder signal
to no longer be proportional to the monitored speed.
Appropriate measures are:
– Using the monitored encoder to also control the drive
– Mechanical solutions
WARNING!
Encoder errors are detected and signalled via a diagnostic bit. This does
not bring the relevant axis to a safe condition.
To maintain safety (Category 3), the diagnostic bit (diagnostic bit 10) in the
user program must be evaluated in such a way that a shutdown occurs if
the axis is in operation (see examples in Chapter 9).
CAUTION!
If there are frequency differences between tracks A and B of the incre-
mental encoder, the track with the higher frequency will be evaluated. Differ-
ent directions of rotation will no longer be detected. The outputs Clockwise
and Anti-clockwise switch to a safe condition. The safe condition is cleared
again as soon as the error is remedied. Hazards that can arise through an
automatic restart must be excluded within the user program.

Safety
Operating Manual PNOZ ms4p

The following is deemed improper use in particular:
}Any component, technical or electrical modification to the product
}Use of the product outside the areas described in this manual
}Use of the product outside the technical details (see Technical details).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
3.2 System requirements
Please refer to the "Product Modifications PNOZmulti" document in the "Version overview"
section for details of which versions of the base unit and PNOZmulti Configurator can be
used for this product.
3.3 Safety regulations
3.3.1 Safety assessment
Before using a unit it is necessary to perform a safety assessment in accordance with the
Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
