4.1.1 Integrated protection mechanisms
Integrated protection mechanisms4-Sicherheitseigenschaften_multi_allgemein
The relay conforms to the following safety criteria:
` The circuit is redundant with built-in self-monitoring.
` The safety function remains effective in the case of a component fail-
ure.
Sicherheitseigenschaften_Relais
` The relay contacts meet the requirements for safe separation through
increased insulation compared with all other circuits in the safety sys-
tem.
Sicherheitseigenschaften_Halbleiter
` The safety outputs are tested periodically using a disconnection test.

4.1.2.1 Operation
Operation4-Funktionen_multi_Basis
The function of the safety system's inputs and outputs depends on the
safety circuit created using the PNOZmulti Configurator. A chip card is
used to download the safety circuit to the base unit. The base unit has
2 microcontrollers that monitor each other. They evaluate the input cir-
cuits on the base unit and expansion modules and switch the outputs on
the base unit and expansion modules accordingly.
The LEDs on the base unit and expansion modules indicate the status
of the PNOZmulti safety system.
The online help on the PNOZmulti Configurator contains descriptions of
the operating modes and all the functions of the PNOZmulti safety sys-
tem, plus connection examples.
