Controller and flow sensor

The present invention relates to a blocking device () for a damper drive, wherein the blocking device () can be transferred by activation from an inoperative state into an alternative activated state. The blocking device () comprises a movably mounted blocking element () which, in a blocking position, blocks an output member () in a safety position. The blocking device () further comprises a drive element () which, when the blocking device () is activated, moves the blocking element () into the blocking position. The blocking device further comprises an activating element () which, when a blocking temperature has been exceeded, activates the blocking device () by an irreversible change in shape. Also disclosed are a damper drive with a blocking device, a fire protection device and a method for operating a fire protection device.

Locking device for a damper actuator

An actuator (M,S) with a motor () and a motor controller () is configurable to operate as a master or a slave to another actuator which is coupled mechanically for driving a common load. For the case where the actuator (M) is set as the master, the motor controller () receives on an input terminal (Y) an external position control signal (pC), generates a motor control signal (sC) for controlling the motor () based on the position control signal (pC), and supplies the motor control signal (sC) to an output terminal (U) for controlling a slave. For the case where the actuator (S) is set as the slave, the motor controller () controls the motor () by supplying to the motor () the motor control signal (sC) received from the master. Controlling the actuators with a master improves workload balancing and reduces damages to transmission mechanics of the actuators.
