SYSTEM DESCRIPTION
By the combination of the TOP Control with pneumatically actuated process valves, the functionality of the Bürkert process valve series is extended. These valves, in connection with the TOP Control, may also be employed in those control applications requiring continuous behaviour of the actuator.
Valve types
The figure below gives an overview of the possible combinations of TOP Control and various pneumatically actuated valves. For each type, various actuator sizes and valve sizes are available (not shown). More detailled information is to be found on the respective data sheets. The product range is being extended continually.
TOP Control Continuous Type 8630
with flat-seat valve Type 2712 (here with flange connection)
TOP Control Continuous Type 8630
with ball valve Type 2655
with Y-valve Type 2700
with butterfly valve Type 2672
with diaphragm valve Type 2730
Various process valves from the Bürkert range can be combined with the TOP Control to suit different applications. Y-, diaphragm or ball valves with control cones are suitable.
14 - 8630
SYSTEM DESCRIPTION
Pneumatically driven piston and rotary actuators may be used to operate them. Both single-acting and double­acting actuators are offered in combination with TOP Control Continuous.
With single-acting actuators, only one chamber in the actuator is pressurized and vented. The pressure produced works against a spring. The piston moves until an equilibrium is set up between the pressure and the spring force.
With double-acting actuators, the chambers on both sides of the piston are pressurized. When the one chamber is pressurized, the other is vented and vice versa. No spring is installed in this actuator version.

Operating module
• The device is operated via 3 keys. 8-digit, 16-segment LC display for showing the setpoint or actual value and for configuration and parametrization via menu functions.
Positioning system
• With single-acting actuators, the positioning system consists of 2 solenoid valves; with double-acting
actuators of four solenoid valves. With single-acting actuators, one valve serves to pressurize the pneumatic piston drive and another to exhaust it. Double-acting actuators contain 2 valves for pressurization and 2 for exhausting.The solenoid valves work on the rocker principle and are driven via the controller with a PWM voltage. This enables great flexibility with regard to actuator volumes and floating speed. For larger pneumatic actuators, the solenoid valve are equipped with diaphragm boosters.
SYSTEM DESCRIPTION
As an option, with single-acting actuators, there are fast pressurizing/exhaust variants with an additio­nal pressurizing valve and an additional exhaust valve. These enable the actuator to be completely pressurized and exhausted more rapidly. This is used with the tight-closure function (see section "

Position repeater (optional)
• 2 inductive proximity switches (initiators) or mechanical limit switches.
Attainment of an upper or lower position of the valve can be relayed via binary outputs e.g. to a PLC. The end settings on the initiators can be adjusted by the owner by means of setscrews.

SYSTEM DESCRIPTION
Operating as a positioner
The actual position (POS) of the pneumatic actuator is measured via the position sensing system. The controller compares this actual value of the position with the setpoint (CMD) , which can be specified as a standard signal. If a control difference (Xd1) exists, a pulse-width modulated voltage signal is sent to the positioning system as the correcting variable. With single-acting actuators, if the difference is positi­ve, the pressurizing valve is driven via output B1; if it is negative, the exhaust valve is driven via output E1. In this way, the position of the actuator is altered until the control difference is zero. Z1 represents a disturbance.

SYSTEM DESCRIPTION
* Operation as a process controller (option)
On operation of the TOP Control Continuous as a process controller, the abovementioned position control becomes a subordinate auxiliary control loop; the result is a cascade control. The process controller in the main loop of the TOP Control Continuous has a PID function. The setpoint specified is the process setpoint (SP) and it is compared with the process variable to be controlled. The actual position (XPOS) of the pneumatic actuator is measured via the position sensing system. The controller compares this actual value of the position with the setpoint (CMD) , which can be specified as a standard signal. If a control difference (Xd1) exists, a pulse-width modulated voltage signal is sent to the positioning system as the correcting variable. With single-acting actuators, if the difference is positive, the pressurizing valve is driven via output B1. If it is negative, the exhaust valve is driven via output E1. In this way, the position of the actuator is altered until the control difference is zero. Z2 represents a disturbance.

* Operation as a flow rate controller (option)
The flow rate controller is a special type of process controller. The process value (PV) is not measured directly via an analog input but calculated in the device by the dp method. According to the algorithm, the flow rate is dependent on the parameters
dium temperature
for 2 pressure transmitters and a temperature transmitter which can be optionally connected.
One pressure transmitter measures the pressure before the valve and a second one after the valve. The temperature is either entered manually in the operating menu or is provided as a standard signal by a temperature transmitter. The kv value is determined internally from the current position of the control valve. For this purpose, a kv characteristic curve is provided in the control valve used.
The density of the medium is entered via the operating menu.

In the case of the flow rate controller, the process parameters are either the volumetric flow rate or, for special applications, the transport velocity at the end of a pumping section.
The volumetric flow rate is represented in m gas pressure of 1013 mbar (abs).
There are special applications for flow rate controllers in which a pumping section is set up after the valve, in which bulk goods enter via an airlock. These bulk goods are blown through the pumping section by the pumping pressure that builds up behind the valve.

The transport velocity corresponds to the volumetric flow rate of the medium, referred to the piping diameter of the pumping section. However, it is not specified for standard conditions, but reflects the velocity of the gas particles at the existing medium temperature. The diameter is entered in the operating menu.

The flow rate controller offers the same functions as the process controller.

See data sheet for dimensions of TOP Control and the variants of the complete device, consisting of TOP Control Continuous, pneumatic actuator and valve.
Installation of the valve
NOTE
The actuator must not be connected. For dimensions and threads, see data sheet for the process valve.
Turning the TOP Control Continuous
If, after installation of the continuous valve, the display of the TOP Control Continuous is poorly visible or it is difficult to attach the cable or hoses, the TOP Control Continuous may be rotated relative to the pneumatic actuator.
Procedure
Disconnect the fluidic connection between TOP Control Continuous and pneumatic actuator.Loosen the fixing screws recessed into the side of the housing (hex socket SW3, see chapter
description - Construction of the TOP Control Continuous
).
System
Rotate the TOP Control ContinuousRetighten the fixing screw with 1.2 Nm moderate torque.Remarke the fluidic connection between TOP Control Continuous and pneumatic actuator, using longer
hoses if necessary.
ATTENTION!
ATTENTION!
If theTOP Control Continuous is lifted during rotation (axially displaced), the mechanical coupling to the position sensor mechanism may be damaged. By turning in the wrong direction (anticlockwise), there is a risk of unhooking the position sensor mechanism. This can be reconnected only with a special tool!
To assure leak tightness of the device (IP65), the screw for connecting TOP Control Continuous and process valve shall be tightened with a torque not exceeding 1.2 Nm!

The flow characteristic k
= f(s) describes the flow through a valve, expressed by the kv value, as a

function of the stroke s of the actuator spindle. It is determined by the shape of the valve seat and the seat seal. In general, two types of flow characteristic are realized: the linear and the equipercentile.
With linear characteristics, equal changes in stroke ds are allocated to equal changes in k
(dkV = n
* ds).

With an equipercentile characteristic, a change in stroke ds corresponds to an equipercentile change in kv value
(dkV/kV = n

* ds).
The operating characteristic Q = f(s) represents the relationship between the volumetric flow Q passing through a valve installed in a system and the stroke s. This characteristic contains the properties of the piping, pumps and consumers. It hence has a different shape from the flow characteristic.

OPERATION AND CONTROLLER FUNCTIONS
Normalized valve stroke [%] (POS)
For positioning applications of control systems, special requirements are usually made on the shape of the characteristic, e.g. linearity. For this reason it is sometimes necessary to correct its shape in a suitable manner.
For this purpose, a transfer member is provided in the TOP Control Continuous which realizes different characteristics. These are used to correct the operation characteristic.
The equipercentile characteristics 1:25, 1:33, 25:1, 33:1 and 50:1 and a linear characteristic may be set.
Normalized position setpoint [%] (CMD)
Furthermore, it is possible to freely program a characteristic via fixed points or have it calibrated automatically.
Entering the freely programmable characteristic
The characteristic is defined via 21 fixed points distributed evenly over the 0...100 % range of the position setpoint. They are separated by 5 %. Each fixed point may be allocated to a freely selectable stroke (setting range 0...100 %). The difference between two adjacent values of stroke may not exceed 20 %.
To enter the point on the characteristic (values of the function), first select the menu item CHR FREE. After pressing the MANUAL/AUTOMATIC key, the first fixed point is displayed (0 %). Next to it is the
value of the function (initially 0 %). With the arrow keys, set a value of the function between 0 and 100 %. After pressing the MANUAL/
AUTOMATIC key, the next fixed point is displayed, etc. Finally, press the MANUAL/AUTOMATIC key to confirm the value of the function belonging to the last fixed point (100 %). The display returns to the menu item

Balancing the pressure transmitters
The pressure transmitters p1 and p2 can be balanced in order to increase the measurement accuracy at small pressure differences. To do this, the feed line behind process valve must be closed, and a constant pressure must be applied to the controller unit. With a pressure < 10 % of the sensor measurement range, the zero-point can be balanced, with a pressure > 55 % of the sensor measurement range, the upper calibration value.
Change the display between p1 and p2 using the arrow keys. If you press the MANUAL/AUTOMATIC key, the displayed value will be confirmed and the other value will be matched to ist. The process will be cancelled with the message P1P2 ERR if the pressure lies between 10 % and 55 % of the des sensor measurement range or if the difference between p1 and p2 > 1.5 %.
