3 Safety
3.1 Intended use
The speed monitor monitors standstill, speed, speed range, position and direction in ac-
cordance with EN ISO 13849-1 up to PL e and EN IEC 62061 up to SIL CL 3.
The safety controller should be installed in a protected environment that meets at least the
requirements of pollution degree 2. Example: Protected inside space or control cabinet with
protection type IP54 and appropriate air conditioning.
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
– Z-frequency monitoring with an additional proximity switch (Ini pnp)
on the same axis
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product

standards and directives for the respective installation site with regard to in-
terference.
3.2 Safety regulations
3.2.1 Safety assessment
Before using a device, a safety assessment in accordance with the Machinery Directive is
required.
The product as an individual component fulfils the functional safety requirements in accord-
ance with EN ISO 13849 and EN 62061. However, this does not guarantee the functional
safety of the overall plant/machine. To achieve the relevant safety level of the overall plant/
machine’s required safety functions, each safety function needs to be considered separ-
ately.
