Utilising the latest technology, it has adopted TFT LCD technology with touch screen for a user-friendly menu and programming interface. The menu includes more diagnostic information, charts, graphs and reports. Also, a more powerful dual-core microprocessor has been chosen to handle the enhanced display and allow more processing for lift functions.
USB technology has been implemented to provide a high speed serial interface to PCs/Laptops and offer an expanded memory system using a USB memory drive.
The USB stick can be used for software upgrades and to back up the parameters.
The system consists of a Base IO module and optional Expansion IO modules. The Base IO module contains the lift/USB microprocessors, power supplies and “controller IO” connections. The expansion IO modules provide IO for the lift shaft and are enclosed in custom designed DIN rail mounting modules, thus the system is modular depending upon the number of floors and features.

ALMEGA & ALMEGA II - Now Even Greener
In response to the ever growing demand for energy efficiency, Lester Controls have developed a range of eco-friendly features designed to integrate with our highly successful ALMEGA series controllers and now our latest range – ALMEGA II.
For modernisation projects where existing DC geared and gearless machines are to be re-used, our DC-Quattro DC control system solution, utilising a Magnetek DC-PWM regenerative drive, provides typical energy savings of over 30% against DC-SCR drives. Against Motor Generator (MG) sets, savings rise to 45%. Additional benefits of this high-tech solution are reduced mains harmonics and power factor improvement.
Our ongoing energy-reduction techniques provide:
- Higher standby power savings
- Higher drive running power savings
Standby Power: How we achieve these savings:
- Car illumination – auto shutdown of car lights when the lift is inactive
- Indicators – auto reduction of indicator intensity output (adjustable) when the lift is inactive
- Fans – automatic power reduction through Drive/Motor/Car Fan switch-off when the lift is inactive
- Permanent Magnet Gearless machines – having zero standby losses compared to DC machines
Running Power: How we achieve these savings:
- Floor-to-floor times are minimised using Lester Controls’ Direct-to-Floor (DTF) system, with running cost savings and improved ride quality performance associated with DTF profiling
- Closed-loop control provides improved speed tracking, further reducing peak current demands and optimising power factor efficiency
- Using Magnetek’s ‘Quattro’ DC and AC fully regenerative drive ranges, power is diverted to the mains supply, eliminating wasteful energy otherwise diverted through dynamic braking resistors
