![]() The test is to be repeated by subtracting weight in 5.0 pound Similarly, starting from normal weight plus 15.0 pounds, Performing each test cycle, the door is to be cycled 2 times to update The door in 5.0 pound (2.26 Kg) increments and the test repeated untilĪ total of 15.0 pounds (66.72 N) has been added to the door. (a)(2) of this section to be the most severe, weight is to be added to (2) At the point determined by the test in paragraphs (a)(1) and Of this section to be the most severe, the door sensor and associatedĬomponents shall withstand 50 cycles of operation without failure. (1) With the door at the point andĪt the weight determined by the tests of paragraphs (a)(2) and (b)(2) (iii) Within 1 foot of the other end of the door at points one, (ii) Within 1 foot of the end of the door, at points one, three, (i) At the center at points one, three, and five feet from the Shall withstand a total of 9 cycles of mechanical operation withoutįailure with the force applied as follows: For this test, a door sensor system and associated components Continuous operation of the motor without cooling is not The cycles are not required to beĬonsecutive. Repeated and measurements made at various representative points across (2) The test described in paragraph (a)(1) of this section is to be The weight of the door is to be equal to the The door so that the axis is perpendicular to the plane of the door. Longitudinal edge of a 1\7/8\ (47.6 mm) diameter cylinder placed across ![]() For a force activatedĭoor sensor intended to be used in an operator intended for use only onĪ sectional door, the force is to be applied by the door against the N) or less force in the up or opening direction. (1) A force activated door sensor of aĭoor system installed according to the installation instructions shallĪctuate when the door applies a 15 pound (66.7 N) or less force in theĭown or closing direction and when the door applies a 25 pound (111.2 1211.13 Inherent force activated secondary door sensors.
