§3071. Operation, Operating Devices and Control Equipment.

(a) Types of Operating Devices.

(1) Operating devices shall be of a type conforming to the requirements of section 3040(a)(1), section 3040(a)(2) and section 3040(a)(3).

(2) Top-of-car operating devices shall be provided and shall conform to the requirements of section 3040(a)(4).

EXCEPTIONS:

1. Elevators having a rise of not more than 15 feet and which do not have access switches at the upper landing.

2. The operation in the down direction may be independent of the down terminal stopping device.

(b) Operation. Operation shall conform to the requirements of sections 3040(a)(4), (a)(5), (a)(6), (a)(7) and (a)(8).

(c) Leveling Devices and Truck-Zoning Devices. (1) A two-way automatic maintaining leveling device shall be provided for elevators with automatic or continuous pressure button operation.

(2) Leveling devices and truck zoning devices shall conform to the requirements of section 3040(a)(5).

(d) Electrical Protective Devices. In addition to the terminal stopping devices required by section 3070, the following electrical protective devices shall be provided and shall conform to the requirements of section 3040(b), except that their operation shall cause the electrical power to be removed from all control valves and from the pump motor.

(1) Emergency-stop switch.

(2) Stop switches in pits.

(3) Stop switches on top of cars.

(4) Hoistway door interlocks or hoistway gate contact locks.

(5) Car-door or gate electric contacts.

(6) Electric contacts for hinged car-platform sills.

EXCEPTION: Devices (4), (5), and (6) need not remove the power within the leveling zones.

(e) Requirements for Electrical Equipment and Wiring. All electrical equipment and wiring shall comply with the provisions of CCR, Title 24, Part 3, Article 620.

(f) Installation of Condensers or Devices to Make Electrical Protective Devices Inoperative. The installation of condensers or other devices to make electrical protective devices inoperative shall conform to section 3040(d).

(g) Control and Operating Circuit Requirements. The design and installation of the control and operating circuits shall conform to the following requirements:

(1) Springs, where used to actuate switches, contactors, or relays to stop an elevator at the terminals, or to actuate electrically operated valves, shall be of the compression type.

(2) The completion or maintenance of an electric circuit shall not be used to interrupt the power to control-valve-operating magnets nor to the pump-driving motor under the following conditions:

(A) To stop the car at the terminal.

(B) To stop the car when the emergency stop switch or any of the electrical protective devices operate.

(3) The failure of any single magnetically operated switch, contactor, or relay to release in the intended manner, or the occurrence of a single accidental ground, shall not permit the car to start if any hoistway door interlock is unlocked or if any hoistway door or car door or gate contact is not in the closed position.

(h) Load-Weighing Devices on Passenger Elevators. Load-weighing devices which will stop the elevator while running shall not be installed in connection with passenger elevators. They may be installed to prevent the elevator from leaving a floor but the setting shall be for a load not more than that which would actuate the relief valve.

(i) Car Emergency Signal. Elevators which are operated at any time without a designated operator shall be provided with an emergency signal conforming to the requirements of section 3041(a).

(j) Load Test Required. Every hydraulic elevator installed hereafter shall be field tested before a permit to operate is issued, and again at intervals not to exceed five (5) years.

(1) The test shall be witnessed by an authorized representative of the Division, or the Division may accept reports of witnesses accepted by the Division as competent. This test shall demonstrate that:

(A) When running the car with rated load in both directions.

1. The rated speed as shown on the crosshead data plate shall not be greater than 110 percent of the actual speed in the up direction with the rated load on the car.

EXCEPTION to Section 3071(j)(1)(A)1:

For elevators installed prior to 3-21-70 the Division may accept a greater percentage of the actual speed.

2. The full load "down" speed shall not be greater than 125 percent of the rated speed as shown on the crosshead data plate.

(B) The relief valve is in compliance with Section 3068(b).

(C) When the car with rated load is stopped at some elevation in the hoistway for a period of 15 minutes, and with the power disconnected, the elevator does not move (drift or creep). Any change in car position which cannot be accounted for by visible oil leakage or liquid temperature change indicates a problem and the need for further inspection, test, or repairs.

(D) The pressure switch if provided is in compliance with Section 3071(m).

(2) A metal, fiber, or plastic tag shall be securely attached to the elevator pumping unit in the machine room, with lettering not less than 1/4 in. (6.4 mm) on a contrasting background indicating the following information:

1. Elevator state number

2. Elevator company who conducted the load test

3. Date of load test.

(k) Out-of-Service Requirements.

(1) When it is intended to discontinue the use of an elevator for an extended period, the power shall be disconnected and the liquid line to the cylinder disconnected.

(2) The car shall be landed in a satisfactory manner.

NOTE: To facilitate reactivation of the elevator, the car should be landed at least 2 feet above the bottom terminal.

(l) Operation of Elevators Under Fire or Other Emergency Conditions.

(1) Elevators with automatic operation shall conform to fire and other emergency requirements as follows:

(A) Elevators with automatic power operated hoistway doors to section 3041(c).

(B) Elevators with manually operated hoistway doors to section 3041(c)(5) and section 3041(c)(6).

(m) Loss of Pressure Device. A pressure switch or other means shall be provided to prevent the liquid in the cylinder or plunger from returning to the tank through an open valve in the event the weight of the platform is removed from the cylinder or plunger.

(n) Photoelectric Tube By-Pass Switch. Elevators equipped with photoelectric tube devices which control the closing of automatic, power-operated car or hoistway doors, or both, shall conform to the requirements of section 3041(b).

(o) Medical Emergency Elevators. All buildings and structures constructed after the effective date of this order that are provided with one or more passenger elevators shall conform to the requirements of section 3041(e).
