System Description

sysTeM desCripTiOn5.

it acto a5.1.

The Control Head Type 8681 has been designed or use as actuation o pneumatically operated process valvesand / or or recording the switching states o these.

g dcto5.2.

The Control Head Type 8681 is used or actuating pneumatically operated process valves.

For process valve actuation, the control head can be equipped with up to three solenoid valves.

For the recording and eedback o the process valve switching positions to a higher-level control, the control headhas been equipped with a contactless position measuring system, which works with three discrete, adjustableeedback signals (Teach-In Function).

The control head and the process valve are interconnected by an adapter. This produces an integrated, compactand decentralized system o eedback, actuation and valve unction. The ollowing advantages over centralizedsolutions working with valve clusters are achieved:

low installation expenditure

easy start-up

higher application-specifc exibility

shorter switching times and less air consumption due to shorter distances between the pilot valve and theprocess valve.

Various pneumatic and electrical connection variants are available.

sc t5.3.

Special eatures o the Control Head Type 8681 include:

easy-to-clean design with IP65 / IP67 protection

high cleaning agent compatibility

use o high-quality materials

modular structure

restrictable R- and P-connections or all pilot valves (solenoid valves)

integrated pressure-relie valve in the inside o the housing or discharging leakage air with connection into thecommon exhaust air connection

collected exhaust air o all valve locations into one common exhaust air connection (by deault equipped with asilencer)

i equipped with several working connections: one integrated non-return valve per connection in the exhaust airduct as protection against aulty switching o the process valves due to return pressure

System Description

poto M stm5.4.6.

The switching positions o the process valves are reported to the higher-level control by eedback signals romthe contactless position measuring system. Connection to the control head is done by means o a simple adap-tation to the process valve's piston.

The recordable stroke range is between 0 and 80 mm.

Three binary eedback signals are evaluated:- Position 1 (discrete S1OUT signal)- Position 2 (discrete S2OUT signal)- Position 3 (discrete S3OUT signal).

The 24 V DC design is additionally available in the order variant "Analog":Order variant: - Position 1 (discrete S1OUT signal)

- Position 2 (discrete S2OUT signal)- Position 3 (o (4...20 ma) S3OUT signal).

Three Teach-In buttons have been provided or comparison with the actual stroke range (see chapter 15.PositionMeasuring System). The switching positions or the position measuring system can be determined with thesebuttons or by means o the service interace (on the electronics module).

An discrete, external eedback signal (standard proximity switch) can also be processed (S4IN, S4OUT).

i ov mo the housing may not be opened when voltage is present.

For a detailed description o the electrical installation, see chapter 10.24 V DC - Design or

chapter 11.AS Interace - Design.For the setting o the Teach-In buttons, see chapter 15.Position Measuring System.

The control head can be installed in any installation position, preerably with the hood ace up.

The control head should be installed such that layers o dust thicker than 5 mm cannot orm; meaning that suchshould be ensured through correspondingly regular cleaning.

Do not apply any leverage eect on the head and do not climb on it.

When sealing the ange rom the outside to the inside, make sure that the inow o cleaning agent is consid-ered and that the drive space o the process valve towards the control head is sealed.

For the installation o the Control Head Type 8681 to a process valve, you will require a process valve-specifchub ange as an adapter.

The hub ange must be adapted to the design o the process valve and produce the mechanical connectionbetween the process valve and the control head. The axial astening is done by two locking screws (shoulder

screws M5), which engage in the middle groove o the hub ange (protection against pulling o). The controlhead can radially slide into any position in 360 arc, seamlessly.

Internal cabling work is not required or any o the AS Interace designs with multi-pole connection, which makesinstallation and start-up on site considerably easier and quicker, reducing the risk o leaks.

However, you will require the correspondingly assembled cable sets with the ollowing pin assignments. Likewise,the jumpers on the electronics module must be set correspondingly (see fgures below).

The cable with multi-pole connection version is especially suited or direct and exible connection to the AS interacecable harness using the ribbon cable terminal (M12 branch circuit, VA branch circuit) that is optionally available.

The optional ribbon cable terminal contacts the AS interace cable harness by means o penetration technology whichallows installation by "clipping in" the AS interace cable harness without cutting and without removing insulation.

The control heads have been confgured as AS interace version with an extended address range (A/B slaves) or62 slaves or optionally as an AS interace version or 31 slaves.

A change between the two confgurations in the control head is only possibly by exchanging the elec-tronic PCB!

I one control head is replaced with another control head having a dierent confguration in the AS interacefeld bus system (e.g. AS interace version 62 slaves (A/B-Slave) to replace a device with AS interace version31 slaves), a confguration error will be generated at the master due to the dierent ID codes!

In this case (intentional replacement), the current confguration must be reprojected in the AS interacemaster. Please read the operating instructions o the used AS interace master!

DeviceNet - Design

dfto12.1.

The DeviceNet is a feld bus system which is based on the CAN protocol (Controller Area Network). It enablesactuators and sensors (slaves) to be networked with higher-level controllers (master).

The control head in the DeviceNet is a slave device according to the Predefned Master/Slave Connection Setstipulated in the DeviceNet specifcation. Polled I/O, Bit Strobed I/O and Change o State (COS) are supportedas I/O connection variants.

With DeviceNet it is necessary to dierentiate between cyclical or event-driven high-priority process messages(I/O Messages) and acyclical low-priority management messages (Explicit Messages).

The protocol process conorms to the dvn fo r a 2010.
