Special conditions for this system
IMPORTANT In order to avoid turbulence and sudden variations in air temperature (thermal shock), the DPS 9000/9xx 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 on the next page. Compliance with these tolerance values is essential to ensure the dependability of the DPS 9000/9xx.
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 < 19°C | ± 1°C | 2.5°C/30 min |
| Hygrometry | 60 % | ± 5 % | 5 % per hour |
Note: The variations used to calculate the gradient are cumulative.
For example: two variations (+1°C and -1°C) during an hour are equivalent to 2°C of variation for an hour.
THE TEMPERATURE OF THE AIR MEASURED AT THE INPUT OF THE CENTRAL COMPONENTS MUST NOT, UNDER ANY CIRCUMSTANCES, BE LESS THAN 15°C.
It is strongly recommended to keep a constant record of the blowing conditions of the conditioned air under the units. This makes it possible to immediately notify any out-of-limits condition and to monitor it over a long period
If the values fall outside the authorized limits, even for a short time, the result can be a breakdown, leading to operational loss.
