Forced ventilation via centrifugal cooling air fan for F600 types

The motor cooling for the Helios F600 smoke exhaust fans takes place in both smoke extraction and ventilation mode
via separate centrifugal cooling air fans (types B KLG, accessories). These cooling air fans are monitored in ventilation
mode by flow monitors (type SWE, accessories).
– Ventilation mode
The cooling air fan must be activated simultaneously with the smoke exhaust fan in ventilation mode. If the airflow
monitor signals a fault, then it is no longer guaranteed that the smoke exhaust fan is supplied with sufficient cooling
air. In order to prevent damage to the smoke exhaust fan, it must be immediately deactivated and a fault signal must
be issued.
– Smoke extraction mode
The cooling air fan must be activated simultaneously with the smoke exhaust fan in smoke extraction mode. If the
airflow monitor or the smoke exhaust fan motor protection device signals a fault, smoke extraction operations must
not be interrupted. A fault signal must be issued. The smoke exhaust fan will run until electromechanical destruction.
