Привод BELIMO BR230

Mode of operation
2-wire open-close control. The actuator is overload-proof and can thus remain energised even at  the end stops.

Signalling
Two microswitches with fixed settings are installed in the actuator for indicating the damper end positions. The position of the damper blade can be read off on a mechanical position indicator.

Manual operation
The hand crank supplied with the actuator can be used for manual operation.The damper function can thus be tested easily.
