Practical Programmable Elevator ControllersThe Mid-American Advantage

Like other independent elevator contractors, we realize that to remain competitive with Otis, Schindler, Kone and Thyssen, we must offer our customers more innovative products and services. One area that was particularly necessary for our installation and renovation business during the past 15 years was having a good microprocessor-based control system. Our experience with several microprocessor systems purchased from other controller manufactur-ers for our new elevator installa-tions and in the renovation of geared and gearless elevators in mid-rise buildings was not satisfactory. The systems were single source proprietary comput-ers designed as dedicated elevator controllers, offering limited flexibility. We found that repairs or modifications to the microcomputer hardware or software could only be made by the manufacturer. This was often expensive and generally had a three or four day turnaround time, frequently causing excessive downtime on our eleva-tors. The systems were sometimes impossible to troubleshoot, and our maintenance mechanics, adjusters and engineers got tired of working with a “black box” whose operation they would never fully understand. As an alternative, we decided to design and build our own controllers. We began by selecting as the main element of the control system, a general purpose industrial-duty microcomputer made by the Square D Company. When we started in 1984, the Square D Symax 300 programmable controller offered an excellent combination of features and cost. After three years of research, development and on-site testing on a wide variety of elevator installations in Chicago, our new control systems performed beyond our expectations. At that time, we felt that this “open system” controller would be equally valuable to other independent contractors, and we began to sell our systems to other independent elevator companies nationwide. In the succeeding years we have utilized other brands of programmable controllers as various manufacturers have improved their PLC’s price/performance ratio and added features that have proven valuable in specific applications. Programmable controller brands we support include GE Fanuc and Allen-Bradley. These systems have proven reliable and maintainable. We recently installed these controllers with GE PLCs on the Space Shuttle launch tower at the Kennedy Space Center where the PLCs are recognized for reliability and maintain-ability.

Controller with GFC

What makes our control systems superior to others on the market today is the use of highly advanced and versatile “Programmable Logic Controllers” (PLCs) from GE Fanuc and Allen-Bradley as the main logic element of all of our elevator control systems. Programmable logic controllers are industrial-duty general purpose microcomputers, originally developed for the machine tool industry. The use of PLCs offers independent elevator contractors a number of important advantages…Proven Performance—Each of these PLC brands has literally thousands of successful industrial installations throughout the United States in factory automation, machine tools and process control applications. Mid-American has sold or installed hundreds of PLC control systems.Reliability—Designed to have high tolerance to heat, humidity, dirt and electrical interference, our control systems operate trouble-free in the worst possible machine room environment. They are hardened for temperature tolerance, power line noise, radio frequency interference, high humidity and physical abuse. They are designed for rapid troubleshooting and parts replacement.Easy To Maintain—Troubleshooting and start-up are greatly simplified with our programmable controller systems. All inputs to the computer system from buttons and switches, and outputs from the system to lights, relays and the motor drive, are individually monitored with a clearly marked LED. Modular design of the PLC allows replacement of any component in only a few minutes.Access To The Control Program—While understanding of or access to the program is not necessary to install or troubleshoot the system, the control program is completely available to our customers. Written in an easy-to-understand “Relay Ladder Logic,” a language that is very similar to

contact and coil hardwired relay schematics, it can be learned in only a couple of days by your elevator mechanics or engineers. Upon execution of a license agreement, Mid-American will provide a fully docu-

mented copy of the program to the purchaser.Easy To Monitor—Real time logical power flow from the inputs, through the program logic to the outputs can be graphically monitored on a laptop computer. The program can actually be “watched” while it’s running the elevator.Field Reprogrammable—All of these programmable controllers have the flexibility to be quickly and easily field reprogrammed to meet specific job requirements. With our systems, it is never necessary to wait weeks or even days for a new “chip” to arrive from the factory to make a small change in the operation of the elevator.Parts Availability—GE and Allen-Bradley distributors are located in every major U.S. city and numerous locations worldwide. These distributors carry a complete stock of PLC components.

The Heart of the System

Programmable Logic Controller

Mid-American Elevator now offers an elevator diagnostic and monitoring system that utilizes a standard IBM compatible computer in the elevator machine room and, optionally, additional central station or display computers located in the elevator contractor’s office, the building manager’s office, and/or the elevator lobby. The system provides instantaneous notification of elevator malfunctions. Sophisticated diagnostics allows immediate identification of the problem and rapid repair. Advanced traffic analysis ensures that your system is tuned and serving the building with optimum efficiency.

The system includes the following features:

Complete graphical displays of the status of each elevator group.

An overview screen showing the status of all elevators in the system.

Detection of up to 64 different elevator faults.

Faults are logged to screen, printer and hard disk.

Historical fault reports selected/sorted by elevator number, date, time, fault or building.

When there is a system fault, the machine room computer will notify the central station computer.

Central station operators can call any machine room in the system to check the status of elevator and view graphical display of group operation.

Troubleshooting help for Mid-American systems.

Electrical schematics on screen (optional).

PLC programming software installed for monitoring or modifying PLC programs in that machine room (optional).

Utilizes standard commercially available control and computer components.
