Robust, reliable and precise - that is what
the newEP LogicDrive drive units stand for. This innovative product
helps farmers or growers accurately control the climate in their
livestock or crop storage buildings. Where effective ventilation is
needed to create the optimum climate for animals or crops, theEP
LogicDrive is the perfect drive unit for operating air inlet valves or
curtains.
Controlled by the climate controller, the LogicDrive positions the air inlet valves to provide the required supply of fresh air and expel unwanted heat and moisture. The LogicDrive delivers excellent performance in its application. Combined with theEP LogicControl control unit and LogicPower emergency power supply, the LogicDrive is also ideal in situations where the power supply can be unstable.
Robust and reliable
The maintenance-freeEP LogicDrive unit is designed and
built to drive ventilation systems. Equipped with a winch belt, the LogicDrive is
the perfect drive unit for accurately opening and closing air inlet valves with
automatic spring mechanisms. Equipped with one or more chain couplings, the Logic
Drive is extremely suitable for accurately positioning ventilation valves together
with rack drives.
The drive power required by the LogicDrive is provided by a
24VDC stepper motor. The wear-resistant gear and worm wheel transmissions in the
Logic Drive convert this drive power into a slow movement with a distinctive high
drive torque. The RLD80 is enclosed in a compact and robust cast iron housing,
fitted with a mounting base. This mounting base allows for a quick and secure
attachment of the LogicDrive. Thanks to the 24VDC stepper motor, the LogicDrive is
highly suitable for applications with an emergency power supply. This allows the
LogicDrive to supply sufficient power to adjust the air inlet valves or ventilation
valves to the pre-set emergency position should mains power fail.
Powerful under any conditions

Intelligent
The LogicDrive is not only powerful, but also
intelligent. The LogicDrive can be controlled by Modbus or a 0-10V
control signal from a climate controller. This control signal is processed
by the LogicDrive’s integrated control to adjust the unit to the exact
position requested. This does not require position feedback.
With
this Modbus or 0-10V control signal, the LogicDrive is easy to set. This
involves setting the start position, the end position and, if applicable,
the emergency position. Adjusting the LogicDrive to an emergency position
requires both theEP LogicPower emergency power supply and LogicControl
control unit.
The control unit of theEP LogicDrive protects the drive
unit against overloading. In the event of an overload, the LogicDrive stops
immediately. The Logic Drive then activates an alarm contact to indicate
that an overload has occurred. This alarm contact is also activated if the
control signal or mains power is lost.
Dust and water resistant
The quality of the LogicDrive is also reflected in the fact that it is both dust and water resistant: The drive unit has a protection class of IP65. The fully-sealed housing also prevents pests, such as red mites, from entering the unit. Thanks to its smooth surface, the LogicDrive is easy to clean.
Logical links
To get the most out of the LogicDrive drive unit, a stable power supply and accurate control is essential. This is possible with theEP LogicControl control unit and LogicPower emergency power supply. These products form the logical link between the LogicDrive, 1-phase mains power and the climate controller.
Optimum control
TheEP LogicControl provides a stable 24VDC power
supply and monitored 0-10V control of the LogicDrive. The LogicControl is
easy to configure to make the best possible use of the LogicDrive’s
capabilities. Should the control signal from the climate controller be lost,
the LogicControl will take over control and the LogicDrive will go to the
pre-set emergency position.
Reliable emergency power supply
TheEP LogicPower makes a ventilation system with a LogicDrive unit even more reliable. The LogicPower is activated if the mains power is lost or instructed to do so by an external alarm, such as a thermostat. In these situations, the LogicPower will serve as the power supply and, if combined with the LogicDrive, adjust the LogicDrive to the emergency position. The LogicPower will also generate an alarm signal.
