Intended use
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 4DI4DOR 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 re-
quirements 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 corres-
ponding air conditioning.
The module PNOZ m EF 4DI4DOR can be used in furnaces in accordance with EN 298. If
the module's relay outputs shut down the entire fuel supply and the furnace is used in con-
tinuous operation, appropriate external measures must be used to establish diversity of the
shutdown elements (requirement of EN 50156-1). For example, an appropriate measure
may be an additional, monitored switching element (contactor or relay), which is controlled
by a safe semiconductor output and is switched in series with both relay outputs.
