KNX S-B2-UP Actuator
 |  |  |  |
The Actuator KNX S-B2-UP controls shadings (blinds, awnings, roller shutters) or windows. The automatic for this may be provided externally or internally. An internal automatic offers numerous options for blocking, locking (e. g. master–slave) and priority settings (e. g. manual–automatic). Scenes may be stored and recalled via the bus.
Two binary inputs may be used for direct operation (e. g. manual push-buttons) or as bus inputs.
 KNX S-B2-UP 230 V AC for a 230 V AC motor |  KNX S-B2-UP 24 V DC for a 24 V DC motor |
Functions and Operation:
- For drive mechanism of shading or window
- 2 binary inputs
- 8 channel scene control for operating position (for blinds also slat position)
- Slat tracking for blinds according to the position of the sun
- Position memory (operating position) with a 1 bit object (Storage and recall e. g. with push-button)
- Position feedback (operating position, for blinds also slat position)
- Control by internal or external automatic
- Setting of the priority of manual or automatic control by time or via communication object
- Mutual locking of two drives by means of zero position sensors avoids collisions e. g. of shading and window (master–slave)
- Blocking objects and alarm messages have different priority so that safety functions always are higher-ranking (e. g. wind blocking)
- Configuration is accomplished by means of the KNX software ETS
