Function And Features; Requirements - IFM Electronic efector100 G15003 Betriebsanleitung

2. Function and features

The evaluation unit is a redundant diverse system to process up to 6 chains of sen-
sors. Typically up to 64 sensors can be connected.
The evaluation unit supplies/monitors the connected safety switches and evaluates
their switching status. If all safety switches are fully operational and correctly
damped, the evaluation unit switches the output stages (solid-state: clocked PNP
and NPN).
The safe state is the state when the output stages are switched off (principle of nor-
mally closed operation, zero-current state).
The evaluation unit complies with the category 4 according to EN 954-1 or the
requirement class 5 according to DIN V 19250/DIN V 19251 and DIN V VDE 0801.
3. Requirements for the hardware configuration
The following requirements must be complied with when using the evaluation unit
G15003.
Product-independent requirements
The safety requirements of the respective application must correspond to the
requirements stated in these instructions. The specified technical data must be com-
plied with. All external safety circuits connected to the system must be designed to
be de-energised (open) in the safe state.
Product-dependent requirements
In case of faults within the evaluation unit which result in the defined safe state, the
evaluation unit must be replaced.
