Note:
The BE and BLE actuator operating control requires a three-wire system. The actuator sense of rotation is switched
by applying the supply voltage to terminal 2 or 3, depending on the desired sense.
The location of the limit switches for all types of actuators is shown for the position without voltage.
For proper operation of a device equipped with electrical actuators, it is recommended that the rated voltage housed
tolerance of 24V±10% or 230V±10%. Power supply devices other than listed above may cause malfunction and will
not be covered by the warranty conditions.

RST/KW1 trigger control gear
The RST/KW1/S version has the limit switches installed in the gear itself. The electrical connections shall be made
by connecting the properly labelled conductors to the electrical system. A fusible trigger is installed in the gear. The
dampers with the RST/KW1/230I, RST/KW1/230P mechanisms, are supplied with the RST/KW1/24... triggering and
control mechanism, together with the 230/24V transformer module type MP230/24.
