Anti-block protection of drives
The anti-block protection protects drives from pollution in case of long downtimes. Heating pumps can for example become so soiled in summer by the accumulation of dirt in the pump that they break down. A frequent switch-on of the pump for a short while can prevent this from happening. Anti-block protection can in principal be provided for the following components:
Thereby a differentiated form of anti-block protection can be set for the switching and continuous drives. The principal operation modes are:
One can find out from the settings of the individual drives, if an anti-block protection function of the relevant drive is carried out or disabled. The anti-block protection only provides the operation mode centrally.
The anti-block protection can be deactivated for switching and continuous drives respectively, to prevent a potential switch-on of pumps with emptied pipes in case of maintenance work. This might be realised e.g. by a mechanical switch, at the display or via a building management system switch.
