3. General Information
3.1. DESCRIPTION
The C
- TOP is a pneumatic control head designed to assure the optimum control of INOXPA process valves. It is compatible
with the majority of PLC (Programmable Logic Controllers) automated systems, with Digital communication, or with bus (AS-
Interface).
It is fitted to the upper part of the pneumatic actuator of the process valve in order to activate and provide remote electrical
indication of the operating position of the valve. The indicators can be of two types:
-microswitches (with mechanical contact)
-proximity inductive detectors (without contact)
C- TOP can be fitted with any process valve available in the food, drink and biopharmaceutical industries.
3.2. OPERATING PRINCIPLE
The C-TOP is a control head that includes signalling and command devices to control all types of (piston) process valves. This
element incorporates the following functions in a single element:
•pneumatic and electrical control of the valve;
•position indicators with feedback
•possibility of communication by (AS-Interface) bus.
It is fitted to the valve’s pneumatic drive. It receives signals from a control panel or from a PLC to control the valve, and sends
signals to the PLC or control panel in order to indicate its status/position.
Moreover, the C
- TOP, has 3 signalling LED’s providing information as to the status of the valve at all times:
-
green led: indicates that the valve is in the ON position
-
red led: indicates that the valve is in the OFF position
-
yellow led: indicates that position 3 has been activated (for example: mix-proof valve).

4. Reception and Installation
4.1. CHECK THE DELIVERY
The first thing to do on receiving the head is to inspect it and make sure that it corresponds to the item that is entered on the
delivery note.
INOXPA checks all of its equipment before packing. Notwithstanding, it cannot guarantee that the goods in question will arrive
at the addressee intact. For this very reason, the item that is received, as well as any other article, must be checked. In the
event that the product is not in good condition and/or all the parts have not been received, the haulier must write up a report
to this end as soon as possible.
4.2. DELIVERY AND UNPACKING
INOXPA does not accept liability should the head, its component parts and any other part they may
be supplied, be improperly unpacked.
4.2.1. Delivery:
Check that all of the parts listed on the delivery note have been received:
•Delivery note.
•Head and a bag with a seal and 2 securing screws.
•Adapter bracket for the pneumatic actuator (whenever it has been ordered).
•Instruction manual.
4.2.2. Unpacking:
•Remove all possible remains of the packing from the equipment.
•Check the head or its constituent parts for possible damage suffered during haulage.
4.3. IDENTIFICATION
All heads are identified with a label. See section 8.2 of the chapter entitled
Technical Specifications for further information.
4.4. POSITIONING
The purchaser or user will be responsible for assembly, installation, commissioning and operation of
the control head.
Position the head in such a way as that after it has been fitted to the valve it can be easily connected up to the compressed air
network, and so that there will be no difficulty in making all of the required electrical connections. Furthermore, it is a good idea
to position the head in such a was as to make it easy to see the status LED’s from a certain distance, in order to be able to
check the valve status comfortably. Leave enough space around the valve/actuator so that the inspection of the head, as well
as maintenance and stripping operations, can be properly carried out.
It is extremely important to be able to have easy access to the actuator air connection device, even when this is in operation.
The
C TOP control head possesses the following fitting options:
NEW INSTALLATIONS:
•INOXPA process valves. No adapter is required: the head is fitted directly on the upper part of the valve drive.
•in valves made by other manufacturers. Easy fitting, all you need to do is to fit an adaptation bracket (See Figure
4.1). In this case, the head position will depend on the type of valve to which it is to be fitted, though normally, it will be
fitted to the upper part of the pneumatic drive. (The signal indicator must possess the dimensions that are given in
Figure 4.2 and 4.3).

8 4.Reception and Installation ED. 2010/11
The adapter bracket can be supplied by
INOXPA as an accessory, although it may also
be made by the purchaser.
The bracket dimensions must be as indicated
on the figure shown here. The measurements
that are marked with an (*) may vary.
The screw sizes are for DIN 912 M5 allen
screws.

REPAIR / REPLACING OLD MODELS:
•replacing INOXPA '94 head. Order the SCV1010 assembly kit (for actuators and butterfly/ball check valve) or kit
SCN1010 (for multi-way valves) along with the head.
•replacing the Bürkert-model head. Order the SCV1011 assembly kit (for actuators and butterfly/ball check valve) or
kit SCN1011 (for multi-way valves) along with the head.
The bracket/adapter must be fitted in such a way as to be properly aligned with the pneumatic
actuator rod.
Failure to observe this recommendation could result in the detectors failing to work correctly.
4.4.1. Butterfly/ball valve with pneumatic drive. Figure 4.4
•It is very important to keep the minimum distance (dimension figure A) for pneumatic drive butterfly valves in order to
enable the stripping of the actuator.
•Should the head be fitted over another valve, it is extremely important to remember that enough space must be left in
order to be able to strip the valve for maintenance. The minimum recommended distance to enable the carrying-out of
head maintenance work would be dimension figure B.
4.4.2. Multi-way valve. Figure 4.4
•With respect to multi-way valves, cutoff valves must be distinguished from tank bottom valves.
•In the event of installing the head over another valve, it is important to remember that enough space must be left in
order to be able to strip the valve for maintenance. The minimum recommended distance to enable the carrying-out of
head maintenance work would be dimension figure B.

air to the C
- TOP
(See
pneumatic
connections 4.7
).
4.5.3. Adjusting the position detectors
In order to place the detectors at the operating position (or detection position, the regulating screw for each detector must be
tightened:
•screw clockwise to raise the detector.
•screw anti-clockwise to lower the detector.
6
Adjust the height
of the position
indicators with a
screwdriver.

The C-TOP control head has been designed to be connected to different voltages:
DC or direct current: 24V
AC or alternating current: 24/48/110/220V
The head is supplied from the factory for a predetermined voltage. If the mains voltage proves to be
different, the electrical components must be changed (solenoid valves, proximity detectors and
electric plate).
4.6.2 Electrical components
All the electrical components used in the C-TOP
head have a built-in pluggable connector which avoids having to carry out any
further interventions or wiring. The printed wiring board has, as a standard feature, the capacity to plug in up to 3 solenoid
valves (V1, V2, V3) and 3 proximity detectors or microswitches (S1, S2, S3).
The default assembly is as follows:
Output:
24V – general output (+ pole for DC)
