The expansion module monitors standstill, speed and direction of rota-
tion in accordance with EN ISO 13849-1 up to PL e and EN IEC 62061
up to SIL CL 3.
Bestimmung/Gertebeschreibung_multi_Zusatz_Modul
The expansion module may only be connected to a base unit from the
PNOZmulti modular safety system.
Bestimmung/Gertebeschreibung_multi_System
The modular safety system PNOZmulti is used for the safety-related in-
terruption of safety circuits and is designed for use on:
 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. slippage or broken shearpin) which cause the fre-
quency 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").
