2.3 ELEVATOR MACHINE
NOTE: Use geared traction machines up to nine floors with moderate-to-heavy
traffic demand, generally not more than three or four cars in a group and for
speeds not exceeding 1.75 mps (350 FPM). Use gearless traction for speeds beyond
1.75 to 2.00 mps (350 to 400 FPM), for ten floors or more and where intensive
traffic is anticipated, i.e., high-rise hospitals, busy headquarters, office
buildings. Gearless elevators are often used in large hospitals for six or
more stops. However if 2.00 mps (400 FPM) is required, the elevator industry
usually supplies 2.50 mps (500 FPM)as the standard entry for gearless traction
machines. Use generator field control for all applications of gearless elevators
and most geared elevators. For motors greater than 11 kw (15 hp), use power
factor correcting capacitors to increase power factor to minimum 90 percent.

elevator service. Maximum acceptable generator voltage is 600 volts. Indicate direction of rotation by an arrow
embossed, engraved, stamped, or cast on the frame. Enclose electric connections at motor generator set in conduit
boxes. Provide adjustable timing device that will automatically shut the set off at [20 to 30 seconds] [3-minute]
predetermined time after the elevator has answered the last registered call.]
2.4.2 Logic Control
NOTE: Use microprocessors for elevator logic control. However, solid state
control is not desirable for any facility which is subject to an erratic building
power supply,or at a remote/island location. In this situation, specify an
electromagnetic switch, relay logic controller. The mechanical design for the
elevator machine room must include the HVAC recommended by the control system
manufacturer.
[Provide commercially available microprocessor controller to enable programmable control of call allocation,
logic functions, door control, speed sensing and car position. Provide a comprehensive and unrestricted method
of accessing the microprocessor memory for elevator diagnostic purposes and a method of reprogramming adjustable
parameters of computerized controls. Store all programming in non-volatile memory. The microprocessor control
system is acceptable only if all hardware, software, and software documentation required to maintain and utilize
the microprocessor is provided, and training is provided to Government Personnel by the equipment manufacturer
and supplier.]
NOTE: Use the following two paragraphs only for large scale commercial freight
elevator operations.
[2.4.2.1 On-Board Diagnostic Panel
Provide, for each individual elevator microprocessor controller, an on-board diagnostic control and LCD display
panel that allows unrestricted access to the comprehensive range of adjustable parameters necessary to perform
installation, adjusting, maintenance, and testing of the elevator. For each elevator group control, provide
a separate on-board diagnostic control and LCD display panel that allows unrestricted access to the comprehensive
range of options and adjustments necessary to perform installation, adjusting, maintenance, and testing of the
elevator group. Provide LCD displays which also provide the capability to display, monitor, and diagnose any
and all fault logs, fault history, trouble calls, and diagnostics. Provide three (3) copies of the complete
manufacturer's software program, with complete software documentation, that enables the same level of unrestricted
access to all controllers of the same make and model, regardless of the installation date or location. Provide
signed certification, from the manufacturer's corporate headquarters, that guarantees that the microprocessor
software and access system will not terminate the unlimited and unrestricted access at any future date.
