EMERGENCY-STOP SWITCHES

WITH ILLUMINATED STATUS INDICATION ACTIVE/INACTIVE

The functional principle of the system is simple as well as effective: If the plant part equipped with the fixely mounted emergency-stop – for example as a module of a production line – is in operation, the emergency-stop signals its readiness for operation by a red illumination. If the module is disconnected from the production line, the emergency-stop is inactive, is no longer illuminated and remains grey. The risk that the inactive and non-illuminated emergency-stop will be activated by mistake thus will be significantly reduced. The SCHLEGEL active/inactive emergency-stop switches fulfil the requirements of the standard DIN EN ISO 13850:2015.

Product configurator

Active illuminated emergency-stops, like e.g. SIL_QRBDUVOOM125, are additionally equipped with an integrated diagnostic unit. It steadily monitors the illumination status and thus ensures the perceptibility of an active emergency-stop. If there is a total or only partial failure of the illumination, the emergency-stop signal is activated automatically and the installation is put into a safe state.
