Abstract
A curtain machine has a sealed control enclosure. The control enclosure, disposed in a machine interior of a machine housing, forms an enclosure interior and is configured to form a moisture impermeable seal separating the environment of the control enclosure from the environment of the machine interior and the external environment of the curtain machine. A motorized threaded member is configured to move a load block within the machine interior, for example to actuate a cable-based curtain mechanism, with both the load block and threaded member disposed outside the enclosure interior. The enclosure interior of the control enclosure includes a control circuit configured to operate the motor, and a mechanical limit switch configured to be mechanically actuated by the load block to stop the motor responsive to the load block moving along the threaded member beyond a predetermined threshold.
