Drive and Control System

Motor: Our 324 Performance Grille is powered by a UL listed, SEW Eurodrive TEFC NEMA4 variable speed motor with sprocket and chain drive horizontally mounted directly to the unitized structure. This operator also features a patent-pending high performance brake, which prevents the curtain from free-falling in the unlikely event of operator component failure.

Control Panel: The 324 Performance Grille is controlled with a wall-mounted starter. This PLC controller features a variable frequency drive with a soft-start and soft-stop at both ends of limit travel. For harsh weather environments, the controller is NEMA 4 rated. Dimensions of the control panel are 20” x 24” x 8.”
