Page 6 HYDROFIT™ Owner’s Information Manual Chapter 1: About Otis Elevator Otis Elevator Company has a long and interesting history that began in the mid- nineteenth century with its founder, Elisha Graves Otis. In 1852, while employed by the Yonkers Bedstead Manufacturing Company in Yonkers, New York, Otis built a hoisting machine with a safety mechanism that prevented the platform from falling if the hoisting rope broke.
Page 7 HYDROFIT™ Owner’s Information Manual The next problem to overcome was development of a power source to run passenger elevators. Factories warehouses with freight elevators were near water, but passenger elevators would be installed in stores, office buildings, and hotels, away from any central power source (this was 22 years before the opening of the first U.S.
Page 8 But no French company could overcome the structural demands of putting elevators inside the tower’s curved legs. Otis Elevator successfully installed elevators, giving the company a chance to display its product at the fair’s centerpiece attraction.
Page 9 1900s, a time when “big business” flourished. Otis Brothers & Co. merged in 1898 with several U.S. elevator companies in Boston, Chicago, and Philadelphia to become the Otis Elevator Company. Forty more, small, independent elevator companies were acquired during the period prior to World War I.
Page 10 1969: Electric Cart United Technologies purchased the Otis Elevator Company in 1975. Otis became a wholly owned subsidiary in 1976. One of the most significant developments in elevator technology was the use of computer chips to make elevator control decisions.
Page 11 Remote Elevator Monitoring (REM ) system, which was introduced in 1985 and installed at an Otis elevator site in the United Kingdom. REM systems monitor elevators 24 hours a day and provide diagnostic information via a telephone line to our technical center. This information assists our technicians in preventing elevator disruptions.
Page 12 HYDROFIT™ Owner’s Information Manual ® Another important technological advance—the Elevonic 411 software based control system—was released by Otis in 1990. These sophisticated Elevonic systems made “real-time” dispatching rules based on changing traffic conditions in a building. They also managed elevator ride quality, energy consumption, motor performance, and all the in-car information displays.

Page 16 HYDROFIT™ Owner’s Information Manual  Do the passengers have enough time to enter and exit before the doors close? There are a number of variables that determine the door’s opening cycle. The minimum time may depend on the number of elevators in the bank and on the distance from a point in the center of the lobby to each elevator.
Page 17 HYDROFIT™ Owner’s Information Manual with passengers helps to alleviate or avert panic. At these times, information from passengers can be of great assistance to emergency personnel.  Is the interior of the elevator adequately lit? Check that all light switches are on, all lamps are lit, and all light diffusers are clean to permit maximum transmission of light.
Page 18 HYDROFIT™ Owner’s Information Manual Firemen’s Service/Special Emergency Service allows control of elevator operation in the event of fire or other time-sensitive emergencies, particularly where immediate access to specific building areas or floors is necessary. Fireman’s Service has two separate operations, or phases.
Page 19 Today's elevators provide a safe, rapid means of passenger transportation. In large part, this is due to advances in elevator technology. The intent of the information presented here is to provide you with a general understanding of how your HydroFit™/HydroAccel elevator system is designed and how it operates.
Page 20 HYDROFIT™ Owner’s Information Manual Elevator Operation In order to gain further understanding of how a HydroFit™/HydroAccel elevator system works, let’s take you through a typical sequence of operation. A passenger registering an elevator call sets into motion a series of actions. The signal is first picked up by the controller, which acknowledges the request by illuminating an indicator on or near the call button.
Page 21 HYDROFIT™ Owner’s Information Manual The Microprocessor Controller The controller is the central nervous system of the elevator. The controller assembly houses electrical, electronic, and microprocessor components that provide three main areas of control: motion, operation, and door control. It is here that all signals are processed.
Page 22 HYDROFIT™ Owner’s Information Manual Otis Field Tool (OFT) provides the maintenance mechanic with a quick means of troubleshooting the elevator’s controller. He or she can make parameter changes, monitor elevator car status, and perform routine diagnostics. By manipulating the buttons, the Otis mechanic can toggle through various display functions.
Page 23 HYDROFIT™ Owner’s Information Manual The third method used to obtain performance information is through the visual means of Light Emitting Diodes, or LEDs. LEDs will turn on or off depending upon the function taking place. The mechanic will use the visual feedback to verify whether or not the function is working properly.
Page 24 HYDROFIT™ Owner’s Information Manual The ERU not only improves passenger safety, but it also installs quickly with little disruption to building tenants. Your elevator has a supplemental emergency supply of power provided by a 12-volt DC battery unit. It is located within a top-of-car integration box mounted to the top of the elevator car.
Page 25 HYDROFIT™ Owner’s Information Manual In the hydraulic elevator, it is the volume of oil being added into the cylinder (and not the pumping action of the pump) that causes the plunger to lift. The pump does not pump pressure, it only produces flow. Pressure results from the restriction of the hydraulic oil to flow.
Page 26 HYDROFIT™ Owner’s Information Manual HydroFit™ Machine-Roomless Tank The Motor The function of the motor is to provide the necessary torque to the hydraulic pump. The motor has been used for decades to provide efficient, low-maintenance power over long periods of time. Hydraulic elevator motors generally range between 15 horsepower (hp) and 40 hp.
Page 27 HYDROFIT™ Owner’s Information Manual Solid-State starting uses power semiconductors instead of contactors. Unlike contactors, power semiconductors can be switched on and off at very high speeds and at specific times during the three-phase 60 Hz power cycle. By controlling the semiconductor’s on/off function during the power cycle, the current can be controlled.
Page 28 HYDROFIT™ Owner’s Information Manual viscosity and the oil cleanliness are important factors for the hydraulic system to operate at peak performance level. The pump is equipped with a strainer to prevent debris from entering the inlet line toward the control valve.
Page 29 The length of these components depends on the type of hydraulic arrangement: HydroFit™ is a holeless type arrangement; the cylinders are mounted to the building’s foundation (above ground).
Page 30 HYDROFIT™ Owner’s Information Manual of 90 degrees for six minutes, the system activates an oil recycling operation. The recycle operation starts the motor pump, which brings the oil back to the tank. The operation of the motor pump and the friction of the oil from its own natural resistance to flow causes the oil to heat.
