controller shall be labeled so as to designate the up and down car
movement.
EXCEPTION: The operating device for signal or automatic
operation elevators.
Car-switch or hand-lever operating levers shall

Starting levers for signal operation elevators.
2. Existing hydraulic
elevators.
(4) Means
shall be provided to operate the elevator from the top of the car during
adjustment, inspection, maintenance, or repair.

regulations, locked.
(D) It may be
of the portable type, provided the extension cord is permanently attached to a
car top fixture so that the device cannot be removed.
(E) It shall be so arranged and connected
that, when operative, the movement of the car shall be solely under the control
of this device, except as provided in Section
3040(a)(4)(G); and
any power-door operating devices shall be inoperative. The transfer switch or
other means for accomplishing this function shall be located between the car
crosshead and that side of the car which is nearest to the hoistway door used
for access to the top of the car.

car, which are equipped with power-opened car doors, the zone shall not extend
more than 3 feet above and 3 feet below the landing level.
(D) For elevators with static controls
arranged to level automatically, the leveling zone shall extend not more than
12" above and below the landing level.

entrance extends into the leveling zone for a second entrance, the leveling
operation for the second entrance shall be inoperative while the hoistway door
at the first entrance is open.
EXCEPTION: The car may be operated by a car-leveling
device at any landing having two hoistway entrances within 2 inches of the same
level, with both car doors or gates and the corresponding hoistway doors open,

application of the brake may occur at the time of or before the completion of
the slow-down and leveling operations.
The brake shall not be permanently connected across the
armature or field of a direct current elevator driving-machine motor nor shall
a single ground, short circuit or static control failure prevent the
application of the brake in the intended manner.
(f) Control and Operating Circuit
Requirements. In the design and installation of the control and operating
circuits, the following requirements shall be met.

devices operate.
EXCEPTION: Dynamic braking, and speed control
switches.
(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 or run if any hoistway door or gate interlock is
unlocked or if any hoistway door or car door gate contact is not in the closed
position.
(4) The failure
of any static control device, speed measuring circuit or speed pattern
generating circuit to operate as intended or the occurrence of a single
accidental ground or short circuit shall not permit the car to start or run if
any hoistway door or gate interlock is unlocked or if any hoistway door or car
door or gate contact is not in the made position.
EXCEPTION: Elevators with the operation described in
Section 3040(a)(5)(E).

the elevator motor or generator field control switches are in the "off"
position.
The means used shall not interfere with maintenance of
an effective dynamic braking circuit during stopping and standing
conditions.
(6) The control
circuits shall be so designed, installed, and maintained that the car speed in
the down direction with rated load in the car, under normal operating
conditions with the power supply on or off, shall not exceed governor tripping
speed or 125 percent of the rated speed, whichever is lesser.
(7) Elevators with a static control shall
comply with the following:
(A) An independent
means shall be provided to limit the speed of an elevator to not more than 150
f.p.m. during leveling, access switch operation and inspection operation should
the normal means to control this speed fail to do so.
EXCEPTION: Elevators with an independent speed
measuring device arranged to remove power from the motor and brake independent
of the static control if the speed of the elevator exceeds 150 f.p.m. during
leveling, access switch operation and inspection.
(8) Where only one of the controller switches
required by Section
3039(b)(5) is an
electromechanical switch, the elevator control shall be arranged so the car
shall not restart after the brake has been set unless the electromechanical
switch has been in the de-energized position during the time the brake was
set.
(g) Out-of-Service
Requirements. When it is intended to discontinue, for an extended
period, the use of an elevator, the cables shall be disconnected, and the car
and counterweights landed satisfactorily, and the power
disconnected.
(h)
Load-Weighing Devices on Passenger Elevators. Load-weighing devices which will
prevent operation of the elevator may be installed provided they function to
prevent such operation only when the load on the elevator platform is in excess
of 125 percent of minimum rated load.
(i) Floating (Movable) Platforms.
Floating platforms which permit operation of the elevator when the car
door or gate is not in the closed position are prohibited.
