4.1.1 Integrated protection mechanisms
Integrated protection mechanisms 4- 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_Halbleiter  The safety outputs are tested periodically using a disconnection test.

4.1.2.1 Operation
Operation 4- Funktionen_multi_Basis
The function of the inputs and outputs on the control system 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 in-
put circuits on the base unit and expansion modules and switch the out-
puts on the base unit and expansion modules accordingly.
The LEDs on the base unit and expansion modules indicate the status
of the configurable control system PNOZmulti.
The online help on the PNOZmulti Configurator contains descriptions of
the operating modes and all the functions of the PNOZmulti control sys-
tem, plus connection examples.
