2.4

Intended use

Combined with safety relay MCR-225, safeCAP SC4 ensures safety-
related release and interruption of a safety circuit. safeCAP SC4 is used to
protect people from work machines with dangerous closing movements. If
safeCAP SC4 is used without the aforementioned safety relay, the operator is
responsible for safety-related release and interruption of the safety circuit.
2.5

Reasonably foreseeable misuse

Any use other than as specified in the section
beyond this is deemed to be improper.
The switch is not suitable for:
use as a two-hand control without the aforementioned relay or independent
calculation of the performance level in accordance with ISO 13849.
use as a two-hand control without validation of the entire system.
use as an emergency stop command device.
use in potentially explosive atmospheres.
