For operating two drives on one window or on one roof flap.
The synchronous module SM3 is a microprocessor-controlled synchronous operation and shut-off control for simultaneous operation of two smoke extraction and/or ventilation drives 24 V DC on one opening element (sash/dome etc.). The design of the synchronous module is determined by the application and the current consumption of the drives.
For operating two drives with signal transmitters, without limit switches, without built-in load disconnection Safe operation for stroke widths up to 1000 mm, independent of the running times of the drives and the material of the windows or roof flaps.
Up to 10 m permissible cable length between SM3 and drives
Compensation of possible running time differences through integrated overrun times n CLOSE direction
Factory preset switch-off thresholds for lifting and lowering operation
Additional configuration options via the service port interface
Configurable signalling contact
Areas of application
For operating two drives with signal transmitters, without limit switches, without built-in load disconnection
If load-related differences occur, they are automatically compensated and exact synchronisation is ensured
In the end positions and in case of overload in the intermediate positions, the drives are switched off by the integrated current-dependent overload cut-off.
After reaching the end position, the synchronous module locks against multiple actuation in the same direction and can only be controlled in the opposite direction.
Defective or missing drives are detected and the control of other connected drives is prevented.
Rated voltage: 24 V DC (-20 % /+25 %)
Permissible ripple of the nominal voltage: 2 Vpp
Cut-off: integrated electronic load cut-off, cut-off values depend on the connected drive,
