34 Pa. Code § 7.61 - Control apparatus
(a) New
passenger elevators having a car speed in excess of 150 feet per minute, except
hydraulic and automatic control-type elevators, shall be controlled by electric
car switches. Passenger elevators having a car speed less than 150 feet per
minute, except the automatic control type, may be operated either by hand
wheels, levers, or electric car switches.
(b) Existing types of control apparatus shall
be subject to change, at the discretion of the Department, when deemed
necessary for safe operation.
(c)
Electric car control switches shall be so designed and installed that, upon the
removal of the hand of the operator, the switch handles automatically return to
center in a locked position. When electric elevators are operated by lever or
wheel, such low voltage and no voltage protection shall be installed and
connected so that the elevator car does not restart upon the restoration of
voltage or service until the elevator operator has first returned the
controlling mechanism to the off position.
