3 About ThinkTop
ThinkTop V20 is a valve-top surveillance unit that provides surveillance of valves during the fluid
handling process. The surveillance unit has been developed with user friendliness and robustness in
mind.
ThinkTop V20 comes with a valve surveillance sensor board for connection to any PLC system. There
are three types of communication interfaces available:
Digital I/O 24 VDC, AS-Interface V3.0, and IO-Link.
The ThinkTop V20 detects valve position through a sensor target attached to the valve stem through a
touch-free sensor system The position is then evaluated and if valid, the corresponding feedback is
returned to the automation system via the communication interface.
V20, V50 and V70 series
ThinkTop comes in three series: V20, V50 and V70. The V20 series is the option for when all you
need is sensing. The V50 series is the compact option with a feature set tailored to valves that require
only one solenoid valve such as butterfly and single seat valves. The V70 series is the more flexible
option that can be configured to meet the needs of the most demanding valve applications such as
mixproof valves.
3.1 About this manual
In this manual, you will find detailed descriptions of how to install and setup the ThinkTop V20 as well
as detailed information about fault finding and maintenance. We recommend that you familiarize
yourself with the content of the manual before you begin installation.

4 Installation
This chapter covers the installation of ThinkTop V20 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
2.5 mm 14 mm

EN

4.1 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.
1Fit 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
2Mount the ThinkTop centred and flat against
the actuator top.
Hold the ThinkTop flat and steady against the
actuator top.
Use a 2.5 mm hex key to lightly tighten one of
the two set screws.
Tighten the first set screw (1...1.5 Nm).
Tighten the second set screw (1...1.5 Nm).

4.2 Electrical installation
1Fit the cable to the M12 connector and
tighten it using a 14 mm wrench (0.6...1.5
Nm).

5 Setup
If open/closed feedback is desired, manual setup as shown in section 5.2 is required on normally
open (NO) valves.
5.1 Unassisted setup
The recommended setup is letting the V20 setup on its own during IO-testing.

5.2 Manual setup
1Perform mechanical installation as shown in
section 4.1
2Move valve to the initial position
The initial position is the position to be
associated with the valve De-energized
signal. If open / closed feedback is desired,
the initial position should be the valves closed
position. For NO valves DE-EN is not the
closed position.
3Perform electrical installation as shown in
section 4.2
4Observe green flashing
5Move the valve to the opposite of its initial
position
6Observe white light [Energized position
feedback]
7Move the valve back to its initial position
8Observe green light [De-energized position
feedback]
Setup is now complete
9Run an IO-test to verify that the system
returns the desired feedback
NOTE
Setup can be cancelled at any step before
step 8 by removing power from the ThinkTop.

5 SetupEN

5.3 Reset
To reset the ThinkTop V20, remove the ThinkTop V20 from the valve and lift it away from the sensor
target while the ThinkTop V20 is still powered.
2066-0190
When the ThinkTop flashes red it has been reset and the ThinkTop V20 is ready for setup.

6 Troubleshooting
Red flashing
If the ThinkTop V20 is flashing red, it is an indication that the sensor target is
missing:
• Verify that the yellow sensor target is mounted correctly
Missing feedback
If no light or signal to the PLC is present:
• Check your cables and your power supply.
• Verify that the valve is operating correctly
• Verify that the sensor target is not loose.
Incorrect feedback
If you are not receiving correct feedback:
• Verify that the valve is operating correctly.
• Verify that the air supply / remote solenoid valve is working correctly.
• If feedback from the ThinkTop V20 is opposite what it should be, perform a
reset as shown in section 5.3, remove power from the ThinkTop then
choose the appropriate setup from section 5.
