It is understood to influence the calibration model of the infrared gas analyzer when a lot of H
2
,
He, and Ar are included in the measurement gas (pressure broadening).
The span gas must use a gas near the composition of the measurement gas when you measure
the gas like the above-mentioned.
l
Purging of instrument inside
The inside of instrument need not be purged generally except for the following cases.
• A combustible gas component is contained in sample gas.
• Corrosive gas is contained in the atmospheric air at the installation site.
• The same gas as the sample gas component is contained in the atmospheric air at the
installation site.
In such cases as above, the inside of analyzer should be purged with the air for instrumentation
or N
2
. Purging flow rate should be about 1 L/min.
If dust or mist is contained in purging gas, it should be eliminated completely in advance.
l
Pressure at sampling gas outlet
Pressure at the sampling gas outlet should be adjusted to atmospheric pressure.
3.5 Wiring
WARNING
• Never power on the product with the top cover (or front door) of the product open.
Turn off external switches and circuit breakers when working with the top cover (or front
door) of the product open.
• NEVER energize the converter or equipment connected to the converter until all wiring work
has been completed.
CAUTION
For the suffix code, Type “-AD”, copper, copper-coated or aluminum conductors are used for
wiring materials.
CAUTION
This equipment conforms to the CE marking
The following wiring installation is required when CE Mark compliant performance is required.
• An external switch or circuit breaker should be installed to power the converter.
• Use external switches or circuit breakers rated 10 A and compliant with IEC947-1 or 947-3.
• It is recommended that the external switch or circuit breaker be installed in the same room
where the converter is installed
• External switches or circuit breakers should be located within reach of the operator and
marked as being the power switch for this equipment.
