2.2 Safety 2200 Safety 2- 2.2.1 Intended use
Intended use 2- Muting_Sicherheit_Bestimmungsgemäße Verwendung
The muting logic element is used to temporarily suspend safety func-
tions (ESPE/AOPD) without interrupting the process (muting) in accord-
ance with EN 61496-1. For a limited time period and a specific
operational phase (e.g. when feeding materials), it will suspend the ef-
fect of safety devices during the working process. Once completed, it
will reset the safety function.
Use of this operating mode and the arrangement of the sensors are ma-
chine or plant-specific and depend on the risk assessment of the ma-
chine or plant.
Be sure that you observe the warning notes given in the other parts of
this configuration guide and in the PNOZmulti technical catalogue.
These are highlighted visually through the use of symbols.
2.2.2 Standards
Standards 2- Muting_Sicherheit_Normen
Knowledge of and compliance with the relevant standards and direc-
tives are a prerequisite for using the muting function. The following gives
an overview of the most important standards:
 EN 61496-1: Safety of machinery – Electrosensitive protective equip-
ment
 EN 60947-5-3: Low voltage switchgear and controlgear - Control cir-
cuit devices and switching elements
 EN 999: Safety of machinery - The positioning of protective equip-
ment
Please note this is not an exhaustive list of safety standards and direc-
tives.
CAUTION!
Failure to observe the safety regulations in this configuration
guide and in the PNOZmulti technical catalogue will render the
