Special conditions for this system
Important: In order to avoid turbulence and sudden variations in air temperature (thermal shock), the DPS 90/9x should be placed at least 2.50 m from the air discharge source.
The forced draught values under the central components must respect the precise conditions described below. Compliance with these tolerance values is essential to ensure the dependability of the DPS 90/9x.
The temperature and hygometry variations are as important as the choice of set point (pt c) for the proper operation of the computer.
| Choice of set point (pt c) | Authorized variation above and below pt c | Gradient | |
| Temperature | 16°C < pt c < 17°C | ± 1°C | 5°C/30 min |
| Hygrometry | 63 % | ± 5 % | 5 % per hour |
Note: The absolute values of the variations are cumulative.
THE TEMPERATURE OF THE AIR MEASURED AT THE INPUT OF THE CENTRAL COMPONENTS MUST NOT, UNDER ANY CIRCUMSTANCES, BE LESS THAN 15°C.
Temperature and hygrometry should be measured at the input of the components of the DPS 90/9x, at the level of the filter air intake.
A non-compliant climatic environment can generate breakdowns or errors, thereby reducing the availability of the system.
