Whether a security system provides sufficient protection against dangerous movement largely depends on the selected minimum distance. It must be ensured that the dangerous movement comes to a stop before the dangerous point is reached – and throughout the entire life cycle of the machine.
A stop time measurement for machines is necessary prior to initial commissioning, after major changes or in case of expected changes due to use, for example brake wear.
During the stop time measurement, SICK measures the time between the activation of a stop signal and the cessation of the dangerous movement of a machine. The measurement results are used to verify the minimum distances according to ISO 13855 Annex D.
Required measures can be taken in time if necessary. Regularly checked measuring instruments ensure that high, continuous inspection quality is guaranteed.
Scope of service:
- Carrying out the stop time measurement in accordance with ISO IEC 17020, using regularly inspected measuring instruments (ISO 17025)
- Taking into account national machine-specific normative requirements (e.g. for older machines)
- Calculation of the required minimum distance between the dangerous point and the technical protection system in accordance with EN ISO 13855
- Drawing up and handing over a measurement protocol (retention period: 30 years)
