BHS SINGLE PHASE
MECHANICAL LIMITS WITH 6 CAMS
BHS is a Motor for springs-balanced sectional doors.
The worm gear makes the BHS irreversible.
Mechanical limit switch: 2 Green cams for operating limits, 2 Red cams for safety limits, 2 Yellow cams for auxiliary controls.
OVERLOAD SAFETY FACTOR
Motor overload safety factor = 4 x the nominal motor amperage because the starting current of the BHS can reach these levels for short periods.
MANUAL OPERATION
In installations of BHS with hand crank or hand chain override, the door and the self braking gear con struction remain always inter-connected. The door will never fall down if a spring breaks. In installations of BHS with decluth device the door and the self-braking worm gear are disconnected du ring the manual operation. In this case the worm gear no longer sustains the door and a spring safety brake is required.
HOLDING TORQUE The BHS drive unit is capable of holding the weight of the door when the spring breaks preventing the door from falling down. The holding capability is the admissible load the worm gear construction can bear.
EUROPEAN DIRECTIVESBHS is made in accordance with product standards EN 13241-1 Doors- and EN 12453 Safety for power operated doors.
