6.5.4 System tightness test
CAUTION
Leaks in the gas supply lines increase the danger of explosion and may
result in inaccurate measurement results.

Action: Tightness test
1.
If the device is already operating, stop the gas consumption by switching off the
power supply, for example.
2.
Supply all inlet gas lines for the measuring equipment with gases at the
maximum pressure values so that the pipelines contain a gas volume.
3. Check all the parts of the system for leaks using a gas detector.
4.
•
If you identify a leak, it must be sealed immediately.
•
Shut off the gas supply for this purpose.
•
Seal the leak.
•
Repeat the test described in step 3.
5.
Do not complete any further action or work before the entire system is tight
and item 4 no longer applies.
7 Commissioning and decommissioning
CAUTION
This should be done by an experienced technician, with a proven knowledge of
electrical installations in explosion proof areas. Always remember to make sure
there is no hazardous condition present during installation. Follow the
instructions below carefully and make sure you have fulfilled all necessary
safety steps before powering up the EnCal 3000.
This chapter describes the main points for commissioning and decommissioning the
measuring instrument. All new devices are supplied with default parameter set. This
default parameter set should generally be sufficient.
It may be that in different ambient conditions in the field, additional adjustments may
be required and integration parameters or other parameters will have to be adjusted a
little. Furthermore, only the streams of gas and the carrier and calibration gas
properties will have to be adjusted. The information required for the standard
commissioning procedure is listed below in chronological order.
