 [Added by G. N. of 10.11.1982.]
 
### 27. Terminal limit Switches. - (a)  Every electric lift shall be provided with upper and lower terminal limit switches arranged to stop the car automatically within the top and bottom over travels from any speed attained in normal operation. Such limit switches are to act independently of the operating device, the ultimate or final limit switches and the buffers.
(b) Terminal topping limit switches may be fitted to the lift-car, in the lift-well, or in the machine room, and such switches shall be brought into operation by the movement of the lift-car.
 
(c) The contacts of all terminal limit switches shall be opened positively and mechanically by the movement of the lift-car.
 
(d) When terminal switches are situated in the machine room, they shall be mounted on and operated by stopping device mechanically connected to and driven by the lift-car without dependence upon friction as a driving means. An automatic safety switch shall be provided which will stop the machine should the tape, chain, rope or other similar device, mechanically connecting the stopping device to the car fail :
 
 Provided that, when the floor controlling or selector of an automatically operated lift is driven in accordance with this requirement, the floor stopping contacts for each terminal floor may serve as a normal terminal floor stopping devices.
 
### 28. Ultimate or Final Limit Switches. - (a)  Electric lifts shall, in all cases, be provided with ultimate or final limit switches arranged to stop the lift-car automatically within the top and bottom clearances independently of the normal operating device and the terminal limit switches, but with the buffers operative. The switches and the oil buffer shall be so arranged that the opening of the switch and the engagement of the buffer shall be as nearly simultaneous as is possible. When spring buffers are employed, the switch shall open before the buffers are engaged.
(b) Ultimate or final limit switches shall act to prevent movement of the lift-car under power, in both directions of travel and shall, after operating, remain open until the lift-car has been moved by hand winding to a position within the limits of normal travel.
 
(c) Ultimate or final limit switches shall be operated by the movement of the lift-car in the lift-well; they shall not be mounted on the lift-car.
 
(d) Every lift having drum machine shall have two final limit switches, one being operated by the machine and the other by the movement of the lift-car.
 
(e) Ultimate or final limit switches shall not control the same relay switches on the controller as the terminal limit switches unless two or more separate and independent relay switches on the controller are provided, two of which shall be closed to complete the motor and brake circuit in each direction of travel. When the ultimate or final limit switches control the same relay switch or switches on the controller as the operating device, or the terminal limit switches, they shall be connected in the control circuit on opposite sides to the terminal limit switches.
 
(f) Ultimate limit switches designed to open the main circuit of the motor may control the same switch or switches on the controller as the terminal limit switches, but when such ultimate limit switches are employed on direct current power supplies, they shall be provided with additional contacts to control the brake circuit.
 
(g) The contacts of all final or ultimate limit switches shall be opened positively and mechanically by the movement of the lift-car. The cam or cams for operating the limit switches shall be of metal.
 
(h) The terminal and the ultimate or final limit switches shall be held in open position when the lift-car is in contact with the overhead structure or resting on the fully compressed buffers.
 
### 29. Tests. - (a)  A contract load test of each new lift shall be made by the Engineer, who is entrusted with the work of installing the lift, in the presence of the Inspector of Lifts, before such lift is put into service for normal and regular operations. This test shall be made to determine whether the machinery and safety gear will operate satisfactorily within the specified limits with full load in the lift-car.
(b) The brakes, limit switches, buffers, safety gears or gears and speed governor if fitted, shall be made to function during the test, and the electrical wiring and connections shall be tested for earthing insulation resistance and general soundness.
 
(c) In the case of traction drive lifts, it shall be ascertained by a trial descent with 1½ times the full load whether the friction between the ropes and the sheave is sufficient.
 
(d) The runway test shall be made with all electrical apparatus operative, except for the overspeed contact or cut-out on the governor. For lifts operating directly from alternating current the governor shall be tripped by hand at the maximum speed obtainable.
 
(e) At each subsequent inspection the safety gear shall be tested with the lift-car stationary and the lift-car shall be lowered to ensure that the safety gear functions correctly.
 
(f) The insulation of the electrical parts of all operating and similar devices shall be tested to withstand an alternating test-voltage equal to 10 times the working voltage for one minute, with a maximum of 2,000 volts, applied between contacts or similar parts, in the open position and between such contracts and earthed parts.
 
### 30. Notices. - In case of automatic lifts the following notices shall be placed in conspicuous position in the lift-car and no other notices shall be fixed in the lift-car :-
(i) The lift shall not be used by more than ............ persons.
 
(ii) On entering or leaving the lift-car, close properly the landing gate and the car-gate.
 
(iii) Do not open the lift-car when the lift-car is moving. The gate should only be opened after the lift-car has stopped opposite a landing gate.
 
(iv) In case of danger, press the alarm button, but leave the lift-car gate closed. Wait inside until the lift-car is brought opposite a landing, and do not attempt to leave the lift-car until the landing gate is opened fully.
 
(v) Children under 12 years of age shall not use the lift unless accompanied by an adult.
