    Connect the ground contact to ground. It can take cables up to 4 mm². Reassure proper grounding. Use the optional pipe kit (see chapter 9) to install the sensor head to horizontal or vertical pipes. 3.2 Electrical Connection If installed in a classified area, the power supply must run through an intrinsically safe repeater. The combination Sensor head / repeater / cable must be within these parameters: Specifications: : Approved repeater specifications.

    2 mA and thus differentiate between system failure (critical error) and service mode (non - critical error). This is essential if you operate the Statox 506 as a safety operated system (SIS). See also chapter 6.3! If you operate the Statox 506 sensor head with a Statox 502 or 503 Control Module, use the schematics as shown in chapter 3.2.2 or 3.2.3.

  • Page 17: Sensor Calibration

    Sensor Calibration  Sensor and sensor head must have the same temperature!  For calibration you need the Statox 505/506 calibration adapter art # 570505, and an inert gas tube 4x1 mm (i.e. art. # 556710) and span gas (allowable concentration see chapter 12.2). If you are not sure that the ambient air is clean, you need synthetic air for zero adjustment.
