Mounting and installation
8.1 General
The PMA1000/PMA1000L is enclosed in a 19" housing. This gas analyzer is intended for use
as a stationary device. The correct installation of the device and proper sample gas condi-
tioning guarantees a long life-time and a minimum of maintenance work. You can opti-
mise the sample gas conditioning by mounting a cooler and fine filter in line before the
sample gas enters the analyzer.
If you are planning to use the analyzer outdoors, please make sure to protect the device
against any weather influences. The climate conditions should be kept as constant as
possible.
Please mount the PMA1000/PMA1000L in a vibration-free environment. If the environment
is not vibration-free, you will need to mount vibration control air springs to de-couple the
enclosure from the vibration source.
The analyzer should not be mounted close to a heat source. The normal operating posi-
tion for the instrument is the horizontal position. The sample gas needs to freely pass
through the air outlet of the analyzer without any special precautions.
Explosion hazard!
WARNING
For general purpose areas ONLY. Don't use the PMA1000/PMA1000L
in hazardous areas or for the measurement of explosive gases.
8.2 Installation examples
The PMA1000 is equipped with an automatic calibration feature.
The time intervals of the sequence control and the switching outputs are integrated in the
functionality of the gas analyzer. Here are two ways to calibrate the analyzer with the Au-
toCal feature:
AutoCal with two test gas lines
„
(for example PG1= zero gas, PG2=span gas)
The sample gas pump turns off after valve Y1 is activated.
AutoCal with test gas and ambient air
„
(for example PG1 = zero gas, PG2 = span gas = ambient air)
The sample gas pump stays on after valve Y1 is activated. The sample gas
pump turns off after valve Y2 is activated.
