  Section 296-96-07190. What construction requirements apply to terminal stopping switches?  

Latest version.
  • A hoistway must be equipped with normal upper and lower terminal stopping switches that are activated by an elevator chassis. Normal upper and lower terminal stopping switches must stop the elevator at the normal top and bottom terminals of travel.
    (1) A hoistway must be equipped with final terminal stopping switches that are activated by an elevator chassis. These switches must stop the elevator if the elevator travels beyond the normal terminals and prevent the elevator from moving in either direction.
    (2) Winding drum machines may use a slack cable switch instead of a bottom final terminal switch.
    (3) Normal and final terminal stopping switches must not control the same switches on the controller unless at least two separate and independent switches are used. At least two of these separate switches must be closed in order to complete the motor and brake circuits for each direction of travel.
