Connection diagram for the BEE24, BEN24, BEE230 and BEN230 actuators
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.
