Ambient Conditions and Limits for Operation and Storage
Although the Awite gas analysis systems are designed for use under rough conditions, some
requirements concerning the location and environmental conditions should be met in order to obtain
a high accuracy of measurement and to avoid damaging the system. For the conditions not listed here,
the specifications from IEC Standard 60359 apply to application group 1.
4.4.1
Installation location
The system is intended for indoor use.
4.4.2
Installation height
The gas analysis system can be operated in areas which are located up to 2,000 mabove sea level
(normal height null, NHN).
4.4.3
Ambient Temperature
In the interior of the casing, the temperature can be 15 °C higher than the ambient temperature.
Therefore, the ambient temperature for the device must be b5 °C and +35 °C in order to
guarantee an exact measurement of the sensors, not to damage the electronic components and to be
able to operate the unit safely. The analysis systems are calibrated at 25°C. All detailed specifications
refer to this temperature, any deviations that occur under significantly changed temperature conditions
are sensor-related.
CAUTION
The temperature inside the device can be up to 15°C higher than the ambient temperature.
Excessively high temperatures can lead to damage to components and reduce the service life of
sensors. Sub-zero (°C) temperatures can destroy electrochemical sensors. This affects the measuring
function and gas leakage can occur. Install the device in rooms with temperatures b5°C and
max. 35°C. The temperature in the control box must not exceed 50°C . Do not install the device in the
hot exhaust air of cogeneration units.
4.4.4
Ambient humidity
The relative humidity must be kept between 0 and 80% .
4.4.5
Mains voltage fluctuations
Mains supply voltage fluctuations of up to ± 10 % of the nominal voltage are permissible.
