About Control SystemsTh e control system is used for the starting and stopping of the vacuum producer, turbo pump or high pressure fan. Th ey also control fi lter cleaning and give condition indications. In the system control panels, additional functions can be built in by selecting options.Control systems must be installed by a certifi ed electrician. Th e control panels conform to electrical protection class IP 54 (IC529). Manufacturing standards conform to EN60204 (IEC204-1), VDE0113A2/381, DIN 57113A2. Main fuses and working disconnects are not included in the control panels.

System Control Panels

Base System Control panels are confi gured with;

• Lockable Main disconnect• Fusing on main feed and control fusing• LED Indicators• Pilot Devices for Operation• Direct magnetic motor starter• Motor overload protection • Pulse control for fi lter cleaning• PLC Control• Connection for Turbo pump Th ermal KLIXON• NEMA 12 Enclosure

Dustcontrol maintains a policy of active development for controls and control systems and recognizes that there are more ”special control” confi gurations available than basic. Th e basic panel confi guration above is the minimum required for the basic operation of an extraction system. When your requirements, or the requirements of the system, become more complex, we will be there. We can customize a control solution for you, from basic to complex multiple system architectures and everything in-between.

Some examples of options available:

• Reduced Voltage StartersSometimes referred to as a soft-start. Th ese devices are pre-progammed to give a gradual application of voltage as a motor starts. Th ey usually slow the motor start to 5 or 10 seconds and reduce the current in-rush to the motor. Th is results in less stress on electrical and mechanical parts and contributes to enhanced reliability of motors, starter components, overloads and the vacuum producer. Let us show you the benefi ts.

• Variable Frequency DrivesCommonly referred to as VFD’s or drives. Th ese devices allow us to program and control the behavior of the motor. Th e available parameters in a VFD let us, not only soft start your vacuum producer, but provide a whole range of operational parameters to make your system smarter. VFD’s can be demand controlled by a PLC to provide vacuum production on demand. Ramp up when the system usage requires it and idle back to save you energy when system utilization is low. As well as the enhanced control, VFD’s provide an un-paralleled degree of feedback for trouble shooting and power quality diagnostics

Dustcontrol USA supplied electrical control panels are UL listed and bear the serialized UL mark listing.

Dustcontrol Canada supplied electrical control pa-nels are CSA approved and bear the CSA mark.

• Touch ScreensTouch Screens can be added to a system control to give the operator more input/output capability. A standard black and white screen can be used to replace indicator lamps and pilot devices and is easily justifi ed on a cost basis. Larger and higher resolution color screens let us program more enhanced feedback for the user and allow the user access to parameters that would not be available from PB’s and indicator lamps. Access to diff erent parameters can be password protected, supervisors can adjust fi lter cleaning directly, for example.

• SensorsDustcontrol can use many diff erent types of sensors in the extraction system to inform the control and operators of diff ering system conditions.

• Proximity Sensors - monitor levels in silos.• Ultrasonic sensors - monitor fi lling levels in containers.• Temperature sensors - monitor motor, pump and exhaust temp.• Flow sensors - control velocity and fl ow rate.• CT Coil - montior current demand on a vacuum producer.• Inductive Position Sensors - feedback on an object’s position

• Network Ready Architecture: we can program the PLC to be network ready and have access to the World Wide Web. Web access ads a whole range of possibilities; remote monitoring, remote diagnostics and software upgrades over the web.

DC Green System

• Lower power consumption

• No micro switches

• Higher peak performance

• Optimum suction performance at all times

• Increased lifetime of the va-cuum system

Why not reduce your carbon footprint and at the same time cut your costs?

DC 11-Module with DC Greensystem

Dustcontrol´s patented DC Green System is a system for the control of vacuum producers that helps to save energy. Th e DC Green System together with our vacuum producers (radial blowers and turbo pumps), can potentially off er you an energy saving with existing or new Dustcontrol vacuum producers of between 40 and 90 percent.

Depending on the number of open outlets, the RPM of the vacuum producer is optimized by the DC Green System, generating just as much vacuum as needed. By using a sophisticated on-demand control with a frequency converter, the maximum performance is also increased compared to a normal system. When no outlets are open the vacuum producer automatically switches to a saving mode. Th is eliminates the need for electrical microswitches at each work station.

Depending on individual cases and the current market price of electricity; payback time for the purchase of the DC Green System is generally between 1-5 years. In summary, lower energy consumption contributes to economic savings, less environmental impact and an increased life span of the equipment.

Your Dustcontrol contact can calculate the estimated saving in your case.
