1.2 Control
The valve control & indication are designed to provide easy and fully technical solutions inany process area. The reguirements for total product flexibility and reliability. together withsuperior performance, are key functions for success within processing areas.
IntroductionThinkTop V50 and V70 take valve control to a new level and use allfeatures available on the Alfa Laval diaphragm, butterfly, single-seatand mixproof valves. While helping to increase production performanceand secure traceability, ThinkTop V50 and V70 provide real-timeinformation on valve operating status 24/7.
Both ThinkTop V50 and V70 are interchangeable with prior ThinkTopversions, and the appropriate variant is selected based on the numberof solenoid valves. With only one sensor target and one adapter,ThinkTop V50 and V70 fit onto all actuators equipped with mushrooms.
ThinkTop V50 and V70 come fitted with features such as Auto Setup,Live Setup and Flex Setup that streamline the setup process, makingit quick and easy. Auto Setup and Live Setup recognise the valvebased on its DNA profile and can complete the valve setup withoutany manual interaction.
The burst seat clean function is available on ThinkTop V70. Thisfunction controls the optimum open position of the valve, making itpossible to achieve up to 90% CIP liquid savings for each seat lift.
ApplicationThinkTop V50 and V70 are designed for use in the dairy, food,beverage, and biopharma industries.
Benefits• Automatic setup• Automatic valve recognition• Automatic selection of tolerance band• Fast Auto, Live and Flex Setup• 360-degree LED indication• Burst seat clean• Exchangeable (threaded) air-fittings• Interchangeable with ThinkTop classics
.
Working principlesThe control unit offers a single sensor solution for diaphragm, butterfly,single-seat and mixproof valves and it can be fitted with up to threesolenoid valves. ThinkTop converts the electrical PLC output signalsinto mechanical energy to energise, or de-energise, the air-operatedvalve, using the physical sensor target mounted on the valve stem.
Installation with Auto Setup or Live Setup is intuitive and fast. Toinitiate Auto Setup, simply press the “SELECT” button and thenthe “ENTER” button to begin the setup sequence. The process iscompleted in accordance with the number of solenoid valves fitted tothe control unit. Alternatively, the ThinkTop can be set up, withoutdismantling the control head, using the built-in Live Setup feature forremote-configuration

Auto setupAuto Setup is a rule-based function. If one of these rules are not present, Flex Setup must be used.
By default, ThinkTop V50 and V70 uses the de-energised/energised paradigm for valve positions feedback.

1.2 Burst clean modeBurst seat clean mode is available for ThinkTop V70 and can be enabled when a ThinkTop V70 with 2 or 3 solenoid valves is setup successfullyusing Auto Setup
The burst seat clean mode is enabled or disabled on the ThinkTop V70 control board. Press "SELECT" (4 times) until LED no 4 flashes, and then press’ENTER" to enable or disable. This option is also available as an IO-Link parameter
The burst seat clean option is from factory disabled by default. However, if it is enabled and there is a manual reset to factory default, the burst seatclean option is disabled.

When the PLC input signal for either upper or lower seat push (Usl, Lsp) goes high, the respective solenoid valve is Energised. As soon as the sensortarget reaches the predefined energised valve position, the solenoid valve is automatically de-energised by the ThinkTop V70.
A two-second electrical and visual feedback (t) is provided as a handshake for successful completion of a burst seat pulse. The PLC input duration mustbe at least 500 ms (d).
If ThinkTop V70 is set up using Auto Setup without the upper seat lift sensor, the function uses the stored setup stroke time for “Lower seat push” plussome extra time for when the solenoid valve is deactivated.

1.2U.S.A. compliance optionApplies to both Digital Interface and AS-Interface, and ThinkTop V70 variants only. The U.S.A. compliance option refers to a bit mapping interface onlyused in USA on Mixproof valves, fitted with 3 solenoid valves. This U.S.A. bitmapping can be enabled after or before auto setup.
U.S. regulations require independent closed position feedback signals for upper seat lift and lower seat push in a Mixproof valve application
The U.S.A. bitmapping are enabled or disabled on the ThinkTop V70 control board. Press "SELECT" (5 times) until LED no 8 flashes, and then press’ENTER" to enable or disable. This option is also available as an IO-Link parameter.
The U.S.A. compliance option is from factory disabled by default. However, if it is enabled and there is a manual reset to factory default, the U.S.A.compliance option remains enabled.

The pneumatic control and indication unit Type 8697 is optimized forintegrated mounting on the DV-ST valve series. Inductive or NAMURlimit switches register the position of the valve. The integrated pilotvalve control single acting actuators.
The design of the control and indication unit is compact and suitablefor tight fit installations. Besides the electrical position feedback signalsthe LED status of the unit is shown directly on top of the unit itself.
The housing is easy to clean and features proven IP protection andchemically resistant materials for use in hygienic processing, in food,beverage and pharmaceutical industries.

.
The pneumatic control and indication unit Type 8691 is optimized forintegrated mounting on the DV-ST valve series. The registration ofthe valve end position is done through a contact-free position sensor,which automatically recognises and saves the valve end positionthrough the teach function when starting up. The integrated pilot valvecontrols single or double-acting actuators. As an option, another typeof interface can be chosen.
The design of the control and indication unit is compact and suitablefor tight fit installations. Besides the electrical position feedbacksignals the LED status of the unit is shown directly on top of the unititself. The housing is easy to clean and features proven IP protectionand chemically resistant materials for use in hygienic processing, infood, beverage and pharmaceutical industries.
