3.1 Intended use
The motion monitoring expansion module monitors safety functions in accordance with
EN61800-5-2 for safe motion monitoring.
The following monitoring functions are performed:
}Safe direction monitoring (SDI-M)
}Safe operating stop monitoring (SOS-M)
}Safe speed range monitoring (SSR-M)
}Safe speed monitoring (SSM)
}Safe stop 1 monitoring (SS1-M)
}Safe stop 2 monitoring (SS2-M)
}Safely limited acceleration monitoring (SLA-M)
}Safely limited acceleration range monitoring (SAR-M)
The expansion module meets the requirements of ENIEC61508 up to SIL3 and
ENISO13849-1 up to PLe.
The expansion module may only be connected to a base unit from the configurable system
PNOZmulti 2 (please refer to the document "PNOZmulti System Expansion" for details of
the base units that can be connected).
The configurable system PNOZmulti 2 is used for the safety-related interruption of safety
circuits and is designed for use in:
}Emergency stop equipment
}Safety circuits in accordance with VDE0113 Part 1 and EN60204-1
}The product PNOZ m EF 2MM meets the requirements of the standards EN 81-20, EN
81-22 and EN 81-50, harmonised under the Lifts Directive 2014/33/EU, and the require-
ments of the standard EN 115-1, harmonised under the Machinery Directive 2006/42/
EC.
}The programmable safety system 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 cor-
responding air conditioning.
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 [ 44]).
