Siemens SITRANS SL - Gas Analyzers OXYMAT 6 and OXYMAT 7; ULTRAMAT 23 Gas Analyzer

6.2 Gas analyzers OXYMAT 6 and OXYMAT 7
CAUTION
Excessive sample gas pressure
Device damage
At the time of delivery, the pressure switch for reference gas monitoring is set to approx. 0.2
MPa (rel.). If the sample gas pressure has to be changed by more than ±150 hPa due to process-
speci󹪝c requirements, the reference gas pressure also has to be changed by the same amount.
Only then is su󹪟cient monitoring functionality of the pressure switch ensured.
To reset the pressure switching point of the reference gas pressure switch
• Contact the Service.
• Have the pressure switching point of the reference gas pressure switch adjusted by a
Siemens technician or someone trained for this scenario.
