Inspection, maintenance and restoration of defined functions

Planned regular and professional maintenance work on the application ensures uniformly high availability of SICK products and reduces unwanted downtimes. Maintenance work includes the inspection, maintenance and restoration of defined functions of SICK products and their interface to the machine or system. This makes it possible to detect performance losses early on and eliminate them. Preventatives measures for preventing errors are also recommended.

Service experts from SICK define the maintenance intervals together with the customers. Individual services can also be put together into a service contract in line with individual customer requirements.

At a glance
  • Inspection of ambient conditions, damage, alignment and contamination of the SICK product
  • Restoration of defined functions
  • Inspection and adjustment of application-specific parameters
  • Archiving of parameters, acceptance test and handover to the employees
