2 Safety
Unsafe practices and other important information are emphasised in this manual.
Warnings are emphasised by means of special signs. All warnings in the manual are summarised on this page.
Pay special attention to the instructions below in order to avoid serious personal injury or damage to the top unit.
2.1 Important information
Always read the manual before using the Unique Control!
WARNING
Indicates that special procedures must be followed to avoid serious personal injury.
CAUTION
Indicates that special procedures must be followed to avoid damage to the Unique Control.
NOTE
Indicates important information to simplify or clarify procedures.
2.2 Warning signs
General warning:
Danger of electrical voltage:
Caustic agents:
2.3 Safety precautions
Installation
Always read the technical data thoroughly (See chapter 6 Technical data).
Always release compressed air after use.
Never touch the coupling between the valve body and the actuator if compressed air is supplied to the actuator.
Always use a power supply that complies with IEC/EN60950-1 or IEC/EN61010-1 standard and limited-energy circuit
requirements.
Operation
Always read the technical data thoroughly (See chapter 6 Technical data).
Never touch the valve or the pipelines when processing hot liquids or when sterilising.
Never touch the coupling between the valve body and the actuator if compressed air is supplied to the actuator.
Always handle lye and acid with great care.
Transportation
Always make sure that compressed air is released.
Always make sure that all connections are disconnected before attempting to remove the valve from the installation.
Always drain liquid out of valves before transportation.
Always used predesignated lifting points if defined.
Always ensure adequate fixing of the valve during transportation - if specially designed packaging material is available it
must be used.

2.4 Loss of air supply
The Unique Control reacts differently to a loss of air supply compared to a regular spring-return actuator. e.g. the LKLA.
TheUniqueControldoesnothaveabuilt-inspringtoreturntheactuator to the de-energised position in cases of air supply
failure. Instead, the Unique Control features a built-in check valve that ensures that the actuator remains in the current
position if the air supply fails.
In the case of electrical power failure, the Unique Control responds in the same way as regular actuators installed with con-
trol heads from the ThinkTop series.
Please refer to the table below for an overview of the actuator responses in different error scenarios.

3 General information
3.1 General information
Concept
Unique Control for butterfly valves is an actuator with integrated automation for LKB butterfly valves. Unique Control is a
hygienic, reliable solution with a focus on simplicity.
The Unique Control complements our existing range of actuators and control units and it provides the opportunity to upgrade an
existing installation.
Unique Control is compatible with all major PLC systems. It is for use in food, dairy and brewery installations and in
biopharmaceutical applications.
Working principle
The Unique Control uses an air spring allowing operation at a significantly lower air pressure compared to a conventional
mechanical spring. The integrated intelligent automation will self-configure and calibrate with a single press of a button. The
actuator is designed for easy onsite configuration as either normally open (NO) or normally closed (NC). The maintenance-free
but serviceable actuator design is tested to perform over one million strokes
The Unique Control has a 360 deg. indication light for visual status.
It also provides the opportunity to monitor the status of the operating air pressure, identifying air leakage or failing air pressure.

Step 2
Be aware that the actuator position marking on the bottom of the
actuator is aligned as shown on drawing (B).
In cases where the actuator position marking is not aligned,
please refer to the troubleshooting section for an instruction on
how to re-align it.

Mount the bracket using the 3 enclosed screws (D).
The tightening torque is 10 Nm.
NOTE!
The enclosed screws are applied with a thread-locking adhesive.
In the case of dismantling and later reassembly, the screws must
be secured with a thread-locking adhesive.
