      • 1) Taking into account self-heating, generated through constant electrical operation with supply voltage.
      • 2) Caused by the permitted temperature range of the O-ring seal, the hydraulic oil and the temperature-dependent signal quality of the position magnet.
      • 3) Relative humidity 55 %.
      • 4) Caused by dry storage of the O-ring in uninstalled state (no coating with oil).
