LockLogic®: proven mechanism and innovative electronics

“As a pioneer in the ventilation and screening sector, we are committed to the topic of innovation in all areas. The connection or interface between mechanical and electronic systems occupies a central position here. This is a great challenge because of the particular conditions governing animal shed and horticultural construction environments.”

The advantages of LockLogic®

  • High levels of functional and operational safety.
  • Saving in wiring.
  • Integrated drive solutions with decentralised intelligence.
  • Saving with a separate reversible contactor control unit.
  • Soft-start and precise overload disengagement / cutout.
  • Combination of frequency inverter and mechanical limit switch.
  • Open interface.
  • Variable speeds for fast movement.
  • Tried and tested in practice.

Open slowly – closing pronto: TurboLogic!

Using the EWA 75 in conjunction with the ESS 40 limit switch system, closing times of less than two minutes can be achieved, specifically in push-rod ventilation systems in open-roof and Venlo glass structures! This unit delivers up to 35 revolutions per minute and torque ratings of up to 1200 Nm. With the Luv/Lee option, the system can move into a rain setting while retaining full operational reliability and safety.

Example: EWA 75 + ESS 40

Open slowly– close fast: SpeedLogic!

SpeedLogic drives are suitable for situations where drive units close at up to three times normal speed on all kinds of ventilation and screening applications. The combination of EWA 10 –  EWA16 power ­drive and SPL frequency inverter makes speeds of up to 15 revolutions per minute (rpm) possible – pre-configured in stages in a user-friendly manner. The frequency inverter makes it possible to dispense with the need for a reversing contactor control unit.

Bus communication at its finest: LanLogic!

LanLogic is a form of intelligent networking based on the EWA 12 to EWA 16 range of drives. This permits precision feedback control accurate to 0.1% which, especially in winter, can help to reduce energy costs in your production greenhouses.

Shifting positions simply and safely: ESS 40

The electromechanical ESS 40 switch system can be used in the TurboLogic combination and as a stand-alone limit switch system or position switch – Thanks to tried and tested Lock END 20 gear limit switches, a safe and reliable process!
