VALVE CONTROLLERSControllers for Dust Extraction Technology

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 installa-tions 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.

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.

HESCH has the skills and technology to tackle any control task for dedusting of filter and dust extraction systems with fibrous filter technology. From micro-controllers to plant control systems for large indus-trial filters we not only provide custom made solenoid

valve controllers but, on request, also the complete control system for the dedusting process.

Valve controllers for all cases

3

System integration...The valve controllers communicate with the process control over digi-tal inputs and outputs or via Profi-bus DP, Modbus or Ethernet TCP/IP (HE 5750).

Expandable...For some solenoid valve control-lers from HESCH the number of controlled valves may be in-creased from 8 up to 1024 by means of expansion modules.

Application

The pressure transmitter HE 1149 is used to record the sys-tem pressure and to monitor the function of solenoid valves by measurements in the pressure tanks. Depending on the meas-ured 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.

5Technical modifications reserved.

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, lo-cally and technically. This flexible concept adapts itself to practi-cally any required number of filter chambers and valves.

The differential pressure measuring transducers from HESCH are univer-sal 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 measure-ment signal from 4...20 mA. The operating state is indicated with an LED.

6 Technical modifications reserved.

The microcontroller-operated valve controller HE 5711 is used for the cycle control of electromagnetic valves in industrial dust filter systems. The flex-ible design concept enables the use as PCB version with spacer sleeves, as standard rail version or as separate control unit in plastic casing with ATEX 22 approval.

HE 5712µP Solenoid Valve ControllerValve controller for industrial filters

The solenoid valve controller HE 5712 is used for the time- or differential-pressure-dependent control of solenoid valves in industrial dust extraction technology. Up to 8 valves are controlled. The valves are activated sequen-tially and monitored for overflow and interruption. Errors are displayedon the controller. The controller is simple to operate through symbol label-ling and the use of LEDs for status indication and as an adjustment aid without complicated menu structures. The differential pressure is directly

measured by the controller; an external sensor is not required. The sepa-rately available connection set with appropriate cable glands as well as pre-assembled cables with valve connectors available in different lengths complement the controller.

The solenoid valve controller HE 5731 is used for the time- or differential-pressure-dependent control of solenoid valves in industrial dust extrac-tion 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 in-terruption. Errors are displayed on the base unit. The controller is sim-

ple to operate through symbol labelling and LEDs for status and differ-ential 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 differ-ential 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.

HE 5760Field Bus Supported Dedusting SystemDedusting system for industrial filtration plants

The system HE 5760 consists of the master controller HE 5760 and the respective valve-I/O-units HE 5725. The dedusting process is chamber-oriented. 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 compo-nents are supplied pre-installed in a control box. The valve connections with moulded valve connectors are included on request.
