Page 9: Installation
3 Installation This chapter covers the installation of any ThinkTop variant within the V50 and V70 families on any Alfa Laval rising stem valve. Tools To carry out the installation, you need the following tools: Hex key Adjustable spanner or flat wrenches 2066-0037 2.5 mm... -
Page 10: Mechanical Installation
3 Installation 3.1 Mechanical installation Mechanical installation is a two-step process, where you mount the sensor target to the actuator stem and the ThinkTop to the actuator top. Fit the yellow sensor target to the actuator stem. Tighten the sensor target by hand or use a 22 mm spanner (1...2 Nm) 2066-0038 Mount the ThinkTop centred and flat against... -
Page 11: Pneumatic Installation
Installation 3 3.2 Pneumatic installation Before you begin the pneumatic installation, cut the hoses to the preferred length. Connect the air hoses between the air connectors on the ThinkTop and the air ports on the valve. For double seat valves, ensure that the hoses run parallel to each other and do not overlap. -

Page 16: Option - Upper Seat-Lift Surveillance
3 Installation 3.6 Option - Upper seat-lift surveillance This section is relevant for V70 variants where feedback for the upper seat lift function in a double seat valve application is required. The parts referred to in this section are available as a seat lift sensor kit, art no. 9615414801. If the valve at hand doesn´t have the holes in the yoke an additional bracket kit is required. - Page 17 Installation 3 Position the valve so that the mechanical target is in front of the sensor by manually controlling solenoid valve two. Fit a nut approximately half way into the thread on the sensor. Fit the sensor in the bushing, so the tip of the sensor is approximately 1–2 mm from the mechanical target of the valve.

Page 18: Option - Valve Speed Reduction
3 Installation 3.7 Option – Valve speed reduction This section is relevant for valve applications where reduction of closing or opening speed is required. The one-way air throttle valves referred to in this section are available as art. no. 9611996114 for ø6 hoses and art. -
Page 19: Option - Valve Closing Speed Increase
Installation 3 3.8 Option – Valve closing speed increase This section is relevant for applications with large valves where increased closing speed is desired. The quick exhaust valve referred to in this section are available as art. no. 9611996116 for ø6 hoses. Mount the quick exhaust valve on the desired actuator air connection and connect the air hose to the corresponding output on the... - Page 20 3 Installation 200000549-6-EN-GB...

Page 21: Setup
4 Setup When the ThinkTop has been installed correctly and is powered up for the first time, it flashes green. You can then begin the setup process. Auto Setup works well for most applications, and we therefore recommend that you run Auto Setup before trying any of the other setup options. -
Page 22: Flex Setup
4 Setup 4.2 Flex Setup Flex Setup allows the setup of any rising stem valve and is a flexible alternative to Auto Setup. However, Flex Setup is not able to check for common installation mistakes. Flex Setup facilitates the detection and linking of valve functions and the related positions or sensor states to the outputs. Because it relies on additional operator input, the operator must be familiar with the content of the user manual. - Page 23 Setup 4 Perform Flex Setup Remove the top cover by turning it counter clockwise and then lifting it upwards. Press the SELECT button two or three times to navigate to either the Seat valve option or the Rotary valve option, then press ENTER. Store the valve positions.

Page 24: Live Setup
4 Setup 4.3 Live Setup Live Setup is especially suited for live commissioning and live replacement. Unlike Auto Setup, Live Setup does not automatically activate the solenoid valves. It waits for all the detected solenoid valves to be energized by the PLC, and then saves the related positions detected by the sensor system. The light guide lights steady green when setup is completed. -

Setup 4 4.4 Options The operational functionality of the ThinkTop can be further customized with the following options. Burst clean If you want to enable the burst clean feature to optimize the cleaning process in a double seat valve application. You can enable this option both before or after setup. - Page 26 4 Setup 200000549-6-EN-GB...

Page 27: Troubleshooting
5 Troubleshooting The following table provides troubleshooting advice to resolve common issues that you might face when working with the ThinkTop. 5.1 Calculating the error code You need the error code to use the troubleshooting table. To determine the error code, you add the numbers to the right of the active LED’s. -

5 Troubleshooting 5.2 Error descriptions Error description Troubleshooting advice The SELECT button is locked Key lock active It can be unlocked by holding the ENTER button for 7s until the 4 first LEDs has come ON . Sensor target missing Verify that the sensor target is installed correctly. - Page 29 Troubleshooting 5 Error description Troubleshooting advice During operation the valve has moved away from the expected position. - Check for manual override of solenoid valves. - Check the operation of the solenoid valves. If air ventilates from both ex- haust and output simultaneously, the SV might be stuck in an intermediate position.
- Page 30 5 Troubleshooting Error description Troubleshooting advice Voltage Low Too low supply voltage has been detected. (Digital version only) - Verify that the voltage is above 21V. Communication with the IO-Link master is lost. Communication failure The valve is returned to fail safe position. (IO-Link version only) - Check the cable connection between the ThinkTop and the IO-Link mas- ter.

Page 32: Tips And Tricks
5 Troubleshooting 5.4 Tips and Tricks Aligning feedbacks by rearranging solenoid valve plugs For example, if you are setting up a ThinkTop with 2 solenoid valves on a double seat valve with only the lower seat lift function installed. Due to the 2 SV ThinkTop comes with SV1 (main) and SV2 (USL) you will find that after you have done the setup that the actual lower seat position of the valve is keyed to the feedback labelled USL and the related blue colour.
