Lift Controllers

D-LC CONTROL SYSTEM
The D-LC controller is suitable for all the operation types, supported by a programmable microprocessor PCB, particularly reliable, easy to install and maintain.
Basic Characteristics:
• 16 stops APB or 8 stops Down collective – selective or 6 stops Full
  collective – selective
• Easy programming and error detection
• Emphasis on the safety of the lift using multiple electrical safety
  settings
• Electric shock protection of the automatic car door and car and shaft
  lighting 230VAC power supply, by an interrupting differential relay
• Simplex or Duplex operation
• Full compliance with ΕΝ 81-1 and 2 regulations
• Support of ΕΝ 81-70 for DDA and ΕΝ 81-72 for fire fighting lifts
  regulations

E-LC CONTROL SYSTEM
This system supports all the operations of D-LC controller extended for lift applications up to 48 stops and groups up to 8 lifts. It is suitable for serial connection with the shaft and cabin elements and essential for high rise lift applications.

VVVF OPERATION
Special care has been taken in the development of VVVF controllers. The advantages of this technology are:
• Environmentally friendly operation due to low energy consumption
• Optimum motor performance even in low RPM
• Smooth motor start and low starting current
• Effective acceleration and deceleration control for comfortable motion
• Lift position and speed control and accurate floor leveling, with the use
  of encoder
• Motor protection from high Voltage and other electrical hazards
• Fully automatic emergency operation
• Elimination of the motor’s electrical noise

Pre-assembled Electrical Installation

The pre-assembled electrical installation is tailor made for each lift and ensures:
• Easy and reliable installation
• Low staff qualification level
• Easy detection of future electrical failures
• Full compliance with the European standards ΕΝ 81-1, ΕΝ 81-2, ΕΝ
  81-70, ΕΝ 81-72 and the directive 95/16 ΕC
