Siemens SIPROCESS GA700 - Commissioning; Requirements

5.4.2.3 Checking CALOMAT 7 for leaks
Procedure
1. Connect a pressure measuring instrument (manometer) to the sample gas outlet.
Measuring range approx. 200hPa rel. to 1000hPa rel. with appropriate measured value
resolution (0.1hPa).
Absolute pressure gauges with correspondingly good resolution are also suitable.
2. Connect the sample gas inlet to a compressed air source via a shuto󹪜 mechanism. The valves
in use must provide a leakage rate <10
-4
hPa*l/s.
3. Pressurize the analyzer module step-by-step with an overpressure of 400hPa.
4. Close the shuto󹪜 mechanism and wait for 5 minutes until the sample gas that 󹪞owed in has
reached the ambient temperature.
5. Note the pressure.
6. Wait 5 minutes. Note the pressure again.
If the pressure change lies under 5hPa, the sample gas path is adequately tight.
This value is based on the tare volume of the measuring module 6 ml and the volume of the
pressure measuring device of 23 ml.

WARNING
Commissioning and operation with error message
If an error message displays, correct operation is no longer guaranteed.
• Check the severity of the error.
• Correct the error.
• If the error still exists:
– Take the device out of operation.
– Do not restart the device.
The same risk continues to apply when error messages are switched o󹪜 or disabled.
