VALVE CONTROLLERS Controllers for Dust Extraction 2010 Technology / 2011
Valve controllers for all cases HESCH has the skills and technology to tackle any control task for dedusting of filter and dust extraction systems with fibrous filter technology. From microcontrollers to plant control systems for large industrial filters we not only provide custom made solenoid valve controllers but, on request, also the complete control system for the dedusting process. Consequently user-friendly With field bus supported solenoid valve control systems, HESCH offers dedusting control systems which can be individually assembled to form a custom made system due to their modular design. Depending on the size of the dedusting plant there are very different requirements on process control. HESCH offers a wide range of solenoid valve controllers from the reasonably priced and variable microcontroller-operated HE 5711 to the comfortable dedusting control system HE 5750 for large industrial filtration plants. Efficient and environmentally friendly... The intelligence of the filter controllers has a considerable influence on the reduction of the emission values and the energy costs. We offer the complete automation spectrum, both for new installations as well as for increasing the performance of existing fibrous filter systems. All valve controllers from HESCH feature single valve tests, cyclic cleaning and post-cleaning and their casing versions may be installed in Zone 22. 2
Expandable... For some solenoid valve controllers from HESCH the number of controlled valves may be increased from 8 up to 1024 by means of expansion modules. System integration... The valve controllers communicate with the process control over digital inputs and outputs or via Profibus DP, Modbus or Ethernet TCP/ IP (HE 5750). 3
Application The pressure transmitter HE 1149 is used to record the system pressure and to monitor the function of solenoid valves by measurements in the pressure tanks. Depending on the measured pressure, it supplies a 4 20 ma signal. Our controllers may also be used for fluidizers. Due to the flexible adjustment of the pulse and oause times over a wide range you can benefit from the advantages of a ready-made control component also for this application. 4 Technical modifications reserved.
The differential pressure measuring transducers from HESCH are universal measuring transducers for small and medium pressures. Measuring ranges between 2.5 and 1000 mbar can be realised. Two connection cables are used for the power supply. The feed current is the measurement signal from 4...20 ma. The operating state is indicated with an LED. The valve controller HE 5750 is a Master-Slave system for large installations. According to the size of the plant the associated slaves required are connected to the master controller per field bus. Each slave controller is assigned to one filter chamber, locally and technically. This flexible concept adapts itself to practically any required number of filter chambers and valves.

HE 5731 µp Solenoid Valve Controller Valve controller for industrial filters The solenoid valve controller HE 5731 is used for the time- or differentialpressure-dependent control of solenoid valves in industrial dust extraction technology. Up to 64 valves are controlled with the base unit and three expansion units. The base unit communicates with the expansions over a RS-485 connection. The valves are activated sequentially and are not chamber-oriented. They are monitored for excess current and interruption. Errors are displayed on the base unit. The controller is simple to operate through symbol labelling and LEDs for status and differential pressure indications. The differential pressure signal is supplied as 4...20 ma value; as a result the hose connection is less susceptible to faults. The controller is available purely as time controller in a version without differential pressure display. Accessories, such as the differential pressure sensor HE 5409, the P-connection set and the valve connector with various line lengths complement the controller.

The dedusting process is chamberoriented. A maximum of 6 chambers with 24 dedusting valves each may be controlled and monitored. The number of chambers and valves can be adapted by simple configuration of parameters. The dedusting processes (dependent on differential pressure or time or pause control dependent on differential pressure) are already installed and can be easily called up in the configuration menus. For simple parameter setting and commissioning the PC software 'Smart-Tool' is available on request. The control components are supplied pre-installed in a control box. The valve connections with moulded valve connectors are included on request.
