System operation
other stages are switched o. On the other hand, no stages of this cabinet are switched
on as long as the temperature does not fall below the hysteresis threshold.
As soon as the temperature falls below the hysteresis threshold, the stages in this cabinet
are released for compensation.
The default settings are:
Fan switching threshold = 28°C/hysteresis = 5°C
Alarm switching threshold = 45°C/hysteresis = 5°C
Overtemperature switching threshold = 48°C / hysteresis = 5°C
This means that the fan switches on when 28°C is exceeded and switches o again when
temperature drops below 23°C. The overtemperature alarm is triggered when 45°C are
exceeded and is reset when the temperature drops below 40°C. The overtemperature
stage switch-o is activated when 48°C are exceeded. After the temperature has dropped
below 43°C.
The overtemperature switch-os for the individual stages are added together so that it
can be determined later on whether, and in which cabinet, there are temperature prob-
