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
– Monitoring for broken shearpin by means of the speed monitor
WARNING!
A single-channel open circuit/input device error is recognised and leads to a
safe condition of the outputs at the relevant axis.
For applications in accordance with PL e and SIL CL 3, the "Overspeed"
output must be integrated into the safety function in every operating mode
and evaluated so that a shutdown occurs if the output switches to a safe
condition ("Overspeed" output = "0").

Safety
Operating Manual PNOZ ms2p HTL
1001401-EN-04 10
CAUTION!
If there are frequency differences between tracks A and B of the incre-
mental encoder and/or between the proximity switches on inputs I10 (I20)
and I11 (I21), the PNOZmulti switches to a safe state if a frequency ex-
ceeds the configured standstill frequency and is greater than 2 Hz. If the
speed monitor detects different directions of rotation, please note:
– With version 1.X devices the PNOZmulti changes to STOP.
– With devices from version 2.0, the axis in question switches 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.
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 [ 29]).
NOTICE
