Oxygen Monitor SGM7.2 7 Placement
7
Placement and putting into operation
7.1 Installation
conditions
The protective gas monitor must be put in a dry and mainly dust-
free place on a stable, flat pad.
•
A socket has to be in the immediate proximity of the
installation place of the SGM7.2, if possible as a separate
electrical circuit, protected with a 10 A fuse.
•
No heat sources or appliances which produce strong
magnetic fields (e.g. electro motors, transformers) should be
put in the proximity of installation place.
•
The working position of the SGM7.2 is horizontal.
A vertical placement is not permitted because of possible
damaging of the gas monitor by heat concentration.
Penetration of liquids into the SGM7.2 can lead to serious
damages or to the complete destruction of the device.
7.2
Setting up of the operating state
If the SGM7.2 has been brought from a cold place to a place of
operation with higher temperature or relative humidity a waiting
period of at least two hours should be attended before switching
on the SGM7.2, in order to compensate the temperature
difference.
1. Put the SGM7.2 on the desired place, regarding the hints in
chapter 7.1.
2. Build the connections from the measurement place to the gas
inlet and outlet of the SGM7.2. Check the connections for
leaks.
3. If a pressure limitation is necessary, place a needle valve
directly in front of the gas inlet (can be delivered by
manufacturer of the SGM7.2).
4. If the measuring gas contains so much water vapor, that the
danger of condensing water in a cold connecting pipe exists, a
water trap must be installed
before
inflow of the measuring gas
into the SGM7.2 (The penetration of water into the hot measuring
cell can destroy it and therefore must be absolutely prevented.)
5. Connect the SGM7.2 to the power supply.
