3. General Terms

3.1. Purpose of useThe CU4 Direct Connect Control Unit is designed for the control of process valves used in the food and related industries.

The CU4 control unit operates as interface between process control and process valve and controls the electric and pneumatic signals.

The pneumatic control of valves is undertaken via the solenoid valves. The control unit controls the valve positions, open and closed, via integrated and external sensors. The electronic module undertakes the task to process the switching signal from the control and to control the corresponding solenoid valves. The electronic module also provides for potential-free contacts. The corresponding light signals in the control unit provide for an external indiciation of the valve positions.

3.2. DesignofCU4DirectConnect(fig.3.2.)

The CU4 Direct Connect Control Unit mainly consists of the following components:

1. The Control Unit base with integrated air channels and electric and pneumatic connections as well as viewing windows with type label.

2. 1 or 3 solenoid valves for the control of the valve actuators and for the seat lifting of double seat valves.

- 1 solenoid valve with 1 logic NOT element for the control of the valve actuators.

3. Sensor module with 2 integrated Hall sensors or 2 external proximity switches to detect the valve position.

4. Electronic module for the electric supply, communication with the control, evaluation of feedback signals and control of solenoid valves as well as the valve position indication through LED.

5. Clamp ring to fasten the CU4 on the adapter.

6. Cover with LED optics.

The cable/s by means of which the solenoid valves are connected with the electronic module must be guided through the cable guide at the rear side of the electronic module. (fig.3.2.1)

3. General Terms

3.3. Functionoftheindividualcomponents

The installation of the control unit is undertaken by special adapters which are available for the different valve types, see chapter5. Adapter. The snap connectors for supply air and pneumatic air to the individual cylinders of the valves are located at the outside of the control unit. In case of control units for valves with turning actuator, the pneumatic air is transferred internally to the actuator. The air supply of the control unit is equipped with an exchangeableairfilter.Observanceoftherequiredcompressedair quality is imperative. Please also see chapter4.5.

The number of the solenoid valves installed in the CU4 dependsonthevalveactuatorstobecontrolled.Singleseatandbutterfly valves and double seat valves without seat lift function require 1 solenoid valve. Control units for double seat valves are equipped with 3 solenoid valves. For the manual actuation, the solenoid valves are provided with a safe handle which is easy to operate. The electronic module installed in the control unit has the task to process the electric signals from the control, to control the solenoid valves and to evaluate the feedback signals from the feedback unit. Moreover, the signalling and indication of the valve positions as well as additional diagnostic functions are undertaken via the electronic module. The electronic module is the interface between control actuators or sensors. Depending on the control type, different modules areavailable,e.g.DirectConnect,AS-interface,Profibusand DeviceNet. The CU4 Direct Connect module described herein provides for the direct parallel wiring of the control.

A feedback unit is required to detect the valve position. The CU4 Direct Connect is equipped with 2 adjustable Hall effect sensors. These are activated by a valve control rod installed on the operating cam. In this way, the open and closed valve position can be detected.The 2 Hall effect sensors are continuously adjustable over anadditional range. Thus, feedback messages for different valveswith different stroke lengths can be adjusted properly. Alternatively, external proximity switches can be connected insteadof the integrated Hall effect sensors when the valve positionindication is undertaken direct at the process valve.

3.3. Functionoftheindividualcomponents

The luminous diodes are arranged at the front side of the electronic module. Their signals are visibly indicated to the outside by an optical window in the cover of the control unit. Beside the open and closed valve position, the existence of the operating voltage aswell as different diagnostic information are indicated. Chapter6.5.“LED indication” contains more details.

The complete control unit has been designed on the buildingblock principle. By exchange of the electronic module, the control type can be changed, e.g. from direct control (Direct Connect) to communication with AS-interface.

Note! Wiring must also be changed.

4.6. Solenoidvalves

In the base of the control unit max. 3 solenoid valves are installed.The 3/2-way solenoid valves are connected with the electronicmodule by moulded cables and plug connectors.

control: effected by pwm-signalhandle: rotary switch at valve

4.7. Throttlingfunction

The operating speed of the valve actuator can be varied or reduced. This may be necessary to slacken the actuation of the valve in order to prevent pressure hammers in the piping installation. For this purpose, the supply and exhaust air of the firstsolenoid valve can be adjusted via the throttling screws respectively allocated in the interface of the solenoid valve. By turning the screws in anticlockwise direction, the inlet or outlet air is throttled.

4.8. NOTelement

Through the installation of the logic NOT element, the closing force of the valve actuator can be increased by additional compressed air. The NOT element conveys the compressed air via an external reducing valve (max. 5 bar) to the spring side of the valve actuator.

Thepressurereducingvalveisfixedto5bar.

Note! The air connection of the NOT element is equipped with an integrated non-return valve. The air hose must be slided into the air connection until it stops - in order to open the non-return valve.

The NOT element is also used for air/air actuators.

6. Electronic module

6.1 Function / Block diagramThe electronic module CU4 Direct Connect operates as interface between superordinated control (PLC) and is connected direct by parallel wiring, i.e. every individual signal is on a separate line. The large input voltage range from 15 to 48VDC provides for versatile connections. All operating ranges within the electronic module such as the control of the solenoid valves, position feedback and LED indication are separated galvanically and can, thus, be operated with different voltages. Control of the solenoid valves is effected in energy-saving manner via pwm-signals.

7.1. General termsFor the internal registration of the valve position indication,the feedback unit with 2 Hall effect sensors is applied. It is usedwhensingleseatandbutterflyvalvesareinstalled.The control of these sensors is effected by magnets assembledon the valve shaft rod. The Hall effect sensors are installed on amovable threaded rod. By means of this assembly, the sensorscan be adjusted via a large range, in accordance with the valvestroke.

7.2. SensorsHall effect sensors (APV valves): H320385Hall effect sesonrs (APV / WCB D4 valves): H337014UB 4,75-5,25 VDC operatingdistanceaccordingtoSPXFLOWspecification

7.3. Adjustment of valve position feedbackBy turning of the adjustment screws on which the Hall effect sensors are installed, the sensors can be moved into the respectively required position to detect the valve position. The o-rings on the adjusting srews prevent accidental displacement of these positions. After the installation of the control unit, check the correct adjustment of the position of the Hall sensor.

7.4. UseofexternalsensorInstead of the internal Hall effect sensors, also 2 external proximityswitches can be connected to the CU4 DC, e.g. for the valve position indication at double seat valves.
