Control valve with TOPControl Continuous
GB
Fluid Control Systems
GENERALINFORMATION
Described in these instructions by way of example, is the commissioning of a single-acting control valve without field bus communication.
You will find the detailed description of the device in the operating instructions for the TOPControl Continuous Type 8630 also in the operating instructions for the process valves on the supplied CD.
Safety instructions
•Comply with the generally recognised rules of practice for the application planning and operation of the device!
•Installation and maintenance work is only to be carried out by suitably trained tradesmen using appropriate tools and equipment!
•Comply with the applicable accident prevention and safety regulations for electrical equipment during operation and maintenance work on the device!
•Always switch off the voltage supply prior to any interventions to the system!
•Remember that pipelines and valves in systems which are under pressure must not be opened!
•Take appropriate steps to rule out inadvertent actuation or unacceptable maltreatment!
•Guarantee a defined and controlled system restart following an interruption to the electrical or pneumatic supply!

ATTENTION EXERCISE CAUTIONWHEN
HANDLING!
ELECTROSTATICALLY ENDANGERED
COMPONENTS / ASSEMBLIES
The device contains electronic components which react sensitively to an electrostatic discharge (ESD). Contact with electrostatically charged persons or objects will damage these components. In the worst case they are immediately destroyed or will fail after commissioning.
Comply with the requirements according to EN 100 015 – 1 in order to minimise or eliminate the possibility of damage through an abrupt electrostatic discharge. Take care also not to touch electronic components when the supply voltage is applied.
Use for the intended purpose
Comply with the directions in these instructions, also the operating conditions and permissible data according to
Datasheet Type 8630, to ensure that the device functions correctly and remains serviceable throughout its life. In the event of noncompliance with these instructions, also of impermissible interventions to the device, we waive all liability and the guarantee forl the device and all accessory parts is cancelled! The device is intended exclusively for use as a positioning and process control system. Any different use or use going beyond this is considered v improper use. Bürkert is not liable for damage resulting from such
use. The risk is carried solely by the user.

CONSTRUCTIONANDFUNCTIONS
Overview
TOPControl Continuous
Actuator
Valve
According to the operating conditions, different process valves from the Bürkert programme can be combined with the TOPControl Continuous. Suitable alternatives are slanted and straight seat control valves, diaphragm or ball valves.
Functions
Position controller
The position of the drive (stroke) is controlled corresponding to the position set-point. The position setpoint can be predetermined by an external standard signal.
Process controller (option)
The TOPControl Continuous is combined in a control loop. The stroke of the valve is calculated from the process setpoint and the process actual value via the control parameters (PID controller). The process set-point can be predetermined by an external signal.
FLUIDCONNECTION
Control air connection
Connector 1 Supply pressure 3 ... 7 bar
The fixing screw (connection between TopControl and process valve) may only be tightened with a maximum torque of 1.2 Nm.
Connector 3:
Exhaust air silencer
Connector 2.2:
For double-acting drives
Connector 2.1: (mounted ex-works)
ra) Action power-off closed (NC): Actuator: Bottom connector
b)Action power-off open (NO): Actuator:Top connector
Installing the valve
•Installation attitude optional; preferably as above.
•Take note of the flow direction; generally applicable for control valves: Free-stream under seat!
•Make sure pipelines are free of all dirt and contamination!
•Make sure the pipelines are aligned before connecting the valve housing.
•In the case of welded housings, be sure to remove the drive before welding in the housing.
