Installation and initiation
7.1 Installation conditions
The protective gas monitor must be set up in a dry and mainly dust-free place
on a stable, flat surface.
•
A socket, preferably as a separate electrical circuit, must be available
in immediate proximity of the installation place, protected with a 10 A
fuse.
•
No heat sources or appliances which produce strong magnetic fields
(e.g. electric motors, transformers) should be put in the proximity of the
installation place.
•
The SGM7 operates in horizontal position.
A vertical placement may cause damage by heat accumulation and is not
permitted.
A liquid entry can lead to severe damage or to the complete destruction
of the device.
7.2
Set-up of operating state
A temperature compensation is required after the transportation of the device
from cold surroundings to a site with higher ambient temperature or humidity
.
A waiting time of about 2 hours
before switching-on must be considered.
1. Install the SGM7 in the favored place (see chapter 7.1).
2. Connect point of measurement and places of gas inlet and outlet of the
SGM7. Pay attention to leak-tightness.
3. If a pressure limit is required, install a needle valve directly in front of the
gas inlet (available from manufacturer of the SGM7).
4. If the amount of water vapor in the measuring gas is likely to cause a
condensation of water in a cold gas pipe, a water trap must be installed
in front of the gas inlet. (The penetration of water into the hot measuring
cell can destroy it and therefore must be absolutely prevented.)
5. Connect the SGM7 to the power supply.
On long transport routes and at unfavorable temperatures the material
of the connecting tubes must rule out any oxygen permeability. The
manufacturer recommends the following materials in dependence on
the measuring conditions:
