1.4 Selector System(s)
1.4.1 Primary Distance Feedback System
The distance feedback loop is taken from a high resolution encoded driven by the hoist machine. Distance feedback device shall have a minimum resolution of 3000 pulses per foot.
1.4.2 Hoistway Tape System
The selector system for the GALaxy controller uses a perforated steel tape that is hung the length of the hoistway. A set of magnets are placed on the tape at each floor having one 8” magnet as the door zone magnet and one to five smaller 2” magnets as binary position preset magnets. The selector is mounted on the car and is guided along the tape by nylon guides to keep the tape and magnets the proper distance from the selector sensors. The controller uses the door zone magnet to determine the elevator’s level position to the floor. At the dead level position, the binary preset inputs are read in to verify that the car is at the correct floor. Figure 1.0 shows a typical tape mounted on the rails.
Figure 1.0: Typical Tape Mounting
1.4.3 Tapeless Positioning System
The GALaxy controller can also be configured to use an absolute encoder, mounted on the live shaft of a governor as the secondary method of gathering position and speed information. The absolute encoder provides accurate position information at all timers, even immediately following a power up and therefore floor pre-sets are not required. The controller uses the door zone magnet, mounted on the rails, to verify the elevator’s level position to the floor. Figure 1.1 shows a typical tapeless positioning system.

1.5 Motor Control Options
1.5.1 Static Drive Control:
The static drive used is either a Magnetek DSD-412 SCR drive or a Magnetek Quattro DC (IGBT) drive. The drive is sized to provide sufficient capacity to handle peak currents of the elevator and operates with high efficiency. The drive regulator is a digital design and uses a digital hand held interface to adjust drive parameters. The interface to the controller is a high speed serial bus and from hard wired enable, run and fault signals. The high speed serial bus is used for the car speed profile, run interface confirmation and drive/motor status information.
All necessary isolation transformers, chokes and filters are provided to isolate the drive and the hoist motor from the line power, where necessary, and to ensure that the harmonic distortion does not exceed the maximum amount as specified by IEEE 5.19.
1.5.2 AC Drive Control:
The AC drive supplied will be a Magnetek HPV-900, Magnetek HPV-600 or KEB AC drive. The drive will be sized to provide sufficient capacity to handle the peak currents of the elevator and will operate with high efficiency. The drive regulator will be a digital design and will use a digital hand held interface to adjust drive parameters. The interface to the controller is a high speed serial bus and from hard wired enable, run and fault signals. The high speed serial bus is used for the car speed profile, run interface confirmation and drive/motor status information.
Isolation transformers and filters are provided as optional equipment to isolate the drive and the hoist motor from the line power. Installation of the proper transformer and filter ensures that the harmonic distortion does not exceed the maximum amount as specified by IEEE 5.19.
AC drives are available, as a standard, with resistors to absorb the overhauling load energy. Fully regenerative units can be provided, as an option), to allow the over hauling loads to feed back power to the building’s electrical system.
1.6 System Optional Features
1.6.1 Hall Call Cross Cancelation
During the modernization of an existing group, GALaxy has the ability to recognize hall calls registered on the existing group riser, and to assign the hall calls to the new group. This feature allows both new and old cars to registered answer hall calls. The first car to answer the hall call will cancel the hall call request on both groups. Prints from the existing group controller are need by GALaxy engineering to design the required interface circuitry.
1.6.2 Hall Call Cross Assignment
GALaxy has the ability to read and latch hall calls in from the building riser buttons in advance of the old group control system so as to assign the hall calls to either the new or the old group. This feature allows both new and old cars to answer hall calls without chasing each other. Prints from the existing group controller are need by GALaxy engineering to design the required interface circuitry.
1.6.3 Security (Optional):
Lobby Security Panel: A key switch per floor is used to lock out the car calls in each car for that floor. Also an additional key switch per floor can be used to lock out both up and down hall calls for each floor.
Car Call Security: A key switch per floor in each car operating panel is used to lock out the individual car call for this car or to enable access to a floor locked out from the lobby security panel.
Card Reader Security: An input per floor in each car is used to enable access to the floor via a car reader security system.
Security Recall (Field Programmable): Upon activation of security, all cars can recall to the security floor and cycle the door to place all the elevators in a known state to properly secure the building.
1.6.4 Machine Room Display (optional):
A VGA flat-panel LCD display and keyboard can be provided inside the controller cabinet. This interface allows access to the Group Display, the Car Diagnostics Display, the Hall Call Display, the Job Statistics, and the Fault Log for each car.
The Group display shows car position, door status, registered car and hall calls, the hall call assignment and the hall call ETA time. The mechanic can enter car calls for each car in the group and hall calls from the keyboard interface.
The Car Diagnostics display shows the status of individual inputs and output. This display also shows the car service, status, current fault, demand velocity, encoder velocity, velocity difference between demand and encoder, car position, position indicator, floor count (learned on setup), Pulse count locations, run command , encoder direction and the direction preference.
The Hall Call Display shows the up and down hall call inputs from the serial hall call boards.
The Elevator Job Statistics Screen displays the number of car, and hall calls, the number of hall calls less than 15, 30, 45, and 60 seconds, the number of hall calls greater then 60 seconds. The display also shows the percentage of calls answered for each category.
The Car Fault Display shows car faults in the order that the faults occurred from the index number on very left of each fault. The fault buffer on the car holds 50 of the last faults in a circular buffer. The fault display shows the fault, the time it occurred, the date, the car position and the number of consecutive occurrences.
The Detailed Car Fault Display shows the standard car fault information plus additional control information that is stored at the instant the fault is recorded. Details of detailed fault information are described in the controller installation and adjustment manual
1.6.5 Remote Monitoring (Optional):
Remote Monitoring Capabilities are provide using a Lift-Net monitoring system by Integrated Display Systems (IDS) to monitor all the banks of elevators. The data collection, data storage and real - time monitoring portion of the system is based on Microsoft Windows, and is able to run on Windows XP Media, Home or Professional operating systems.
The Lift-Net system is a network - based and is capable of interfacing with all makes and types of elevator / escalator control systems. The system collects data via a serial data link to the controller. The system is capable of operating on any TCPIP based network system including but not limited to Ethernet, Token Ring, Arc-net and Lift-Net. The addition of unlimited monitoring terminals is possible on the network.
Monitoring terminals operate "peer to peer" without a single server, and the failure of a single network device does not affect the operation of the rest of the system. The system provides multiple banks, including multiple buildings, on a single monitoring terminal screen. The system is capable of simultaneous monitoring of at least one hundred elevator / escalator units on a single monitoring station. All monitored banks are visible from any monitoring terminal on the network. Entry into the network is multi-level password protected.
The system is capable of real time display of all monitored status points on all monitored equipment. Fault and event notification screens and audible alarms are immediately displayed on selected monitoring stations, based on Boolean logical combinations of the monitored status points. Different fault and event tables are defined on a per-bank basis. The system collects and stores all status, fault and event information for later reporting and analysis. The system provides statistical analysis of hall call response times, traffic patterns, fault conditions, service logs and security usage in graphical and tabular format.
