INSTALLATION

1. VCS - VALVE CONNECTION SYSTEM

The Valve Connection System, VCS in short, was designed to link together as many valves as possible in an easy, quickand economic way.

1.1 Structure

With this new valve connection system, you can connect up to 127 valves with 2 solenoid coils each (bistable valves) andup to 254 sensor inputs with a single cable and a quick-contact technology.

Fieldbus systems (e.g. Interbus-S or Profibus-DP) are increasingly being used in installations and machines to connectsensors and actuators to a controller (PC or PLC). It is in this kind of structure that the VCS is integrated together with itsVCS interface. The VCS interface communicates with the higher-level fieldbus system and transmits the switchinginformation to the valves. The corresponding feedback (C) from the digital sensor inputs (limit switches) is transmitted overthe line to the VCS interface and from there to the fieldbus system.

The valves or nodes in the VCS line are connected with each other and to the VCS interface (I) over a profiled 2-wire VCScable (G). Power as well as data are supplied to each valve over this VCS cable. To enable easy and quick connection ofthe valves to the VCS cable, ASCO/JOUCOMATIC’s engineers have designed a special VCS connector which is fitted ontothe valve and into which the profiled 2-wire VCS cable is placed. When the lid of the connector is snapped shut, the vampire-type plug automatically provides for immediate contact of the wires of the VCS cable which is also automatically cut to length.The node is connected. Each VCS connector is equipped with a data repeater to bridge a distance of up to 20 m betweentwo valves. This allows for designing large valve systems. No tools are necessary to fasten the lid. You simply snap it shut.No cable cutting, stripping or screwing is required.

In the basic version, the VCS interface is connected to a VCS power supply (P). Depending on the number of valves in thevalve connection system and its size, additional power supplies can be clamped directly onto the cable to provide for anappropriate power output and compensate for any drop of voltage.

In order to ensure the highest possible transmission protection, the VCS line is structured in the form of a loop system, i.e.the last valve in the line must again be connected to the VCS interface. The advantage is that the transmitted data is fedback to the VCS interface for comparison. The outputs are switched only after the transmitted data and the feedback datais 100 % identical.

1.2 DiagnosticsThe VCS has a fine-diagnostic feature. Each VCS connector cyclically transmits diagnostic information which is analysedby the VCS interface. As a result, the VCS system detects:

•valve low voltage,•VCS connector overheating,•overcurrent at valve output

The VCS interface also has comprehensive error analysis features.It is provided with an RS-232 interface which can be connected to a PC. The system can be started up (even withoutfieldbus) and analysed with the supplied diagnostic software.The following functions are activated over PC:

•setting of valve outputs,• reading of sensor inputs,• reading of diagnostic information,•checking of actual configuration,•address allocation.

The VCS system consists of four principle components (see following pages): A VCS connector to be mounted to a solenoid valve or spool valve (C) The VCS interface adapted to the protocols Profibus-DP, Interbus-S and Device-Net (I) The VCS power supply (P) The green VCS cable (G) + the black cable (b) for separate power supply for outputs

Group error

For group errors, the number of the faulty VCS connector can be indicated by LEDs „100“, „10“, „1“. For this purpose, setthe „ERR“ switch to ON (see chapter 6.4).

2.4.4 LED indicatorsA flashing sequence is run as soon as the VCS interface is switched on. Subsequently, „RUN“and „27V“ are permanently lit. See chapter 6.1 if these controls do not light up. The „DATA“ LEDindicates a general communication problem. LEDs „>T“, „<V“ and „OUT“ indicate group errors.For detailed information, see chapter 6.1 (operative malfunction).

ERR - Error : indicates where the error is located with the help of the LED indicators (see above)

TEST - Test mode : locates an interruption in the VCS loop (see chapter 6.3)

SIZE : defines the address space of the VCS interface in the fieldbus system and/or PLC. The addressspace can be adjusted to the number of VCS connectors used. Unoccupied address space canthus be set free for other control operations.

The address space must always be larger than the number of VCS connectors in the loop; otherwise anerror is reported on the LED indicators when the system is started.

3. POWER SUPPLY ON VCS LOOP

3.1 PrincipleOn principle, valve connection systems can be designed with a single cable (green VCS cable) or with two cables (separateblack power cable).In a single cable structure, the inputs and valve outputs are supplied over the VCS power supply. Power supply andcommunication is made over the green VCS cable.In a two-cable structure, the outputs are supplied over the black power cable (power supply). The inputs and the electronics integratedin the VCS connectors are supplied over the green VCS cable (VCS power supply) which is also used for communication.Mixed systems, in which VCS connectors with and without black power cable connection are used, can also be set up (see chapter 1.1)

VCSINTERFACE

The supply of power to the VCS loop mainly depends on the rating of each coil in the application.The following diagrams show the different supply options:• for coils 2.4 W (wattage value of coil in cold state)• for coils > 2.4 W (wattage value of coil in cold state)• for systems with a mixture of coils rated ≤ 2.4 W and > 2.4 W

The outputs and inputs and the electronics ofthe VCS connectors are supplied with powerexclusively over the green VCS cable.

i The type of electrical power supply and the required quantity depend on the number, type and consumptionof spool valves/solenoid air operated valves in the VCS loop and on the length of the VCS loop.

The components can be defined in the following ways:

• Directly according to the type of application (see chapters 3.2, 3.3 & 3.5) with the help of the diagrams inaccordance with the number of connectors in the loop and its length.

• With selection charts (see chapter 3.6) for coils ≤ 2.4 W or for 1.6 W coils of for MEGA spool valve islands.

The required quantity of power supplies can quickly and easily be estimated over these two methods providedthat the system is equipped with one connector type and coils at one consumption level.

• Systems with many different types of components require a detailed estimation of the necessary quantity of powersupplies. To request an estimation, please fill in the VCS Application Requirements Form on page 55 and consult us.

Up to 127 VCS connectors can be fit into one cable loop (with and without inputs).The cable length between two VCS connectors and between a VCS connector and a VCS interface must not exceed 20 m.All inputs/outputs are supplied over the green VCS cable. The output rating is limited to max. 2.4 Watt (100 mA) per output.Depending on the length of the line, the output current, the simultaneity factor (simultaneous switching of outputs) and thenumber of VCS connectors, one or more additional VCS power supplies may have to be used for intermediate power supply.The following applies (worst case calculation):

3.2.1.1 VCS connectors with inputsRequired number of VCS power supplies:• All valves are supplied with power over the green VCS cable.• All VCS connectors are provided with inputs and max. 1 output is switched per VCS connector (881 57 805).• Distance between 2 connectors: 20m• Solenoid coils : = 2,4 W.

This application, in which 37 VCS connectors are connected to a loop 131 m long, requires two 27 V – 3.1A power supplies(see diagram below). The 2nd power supply must be connected to the green VCS cable with a VCS adapter round/flat881 57 855 (see chapter 2.7.2) It must be placed in the middle of the loop.The additional power supplies must be divided up equally between the number of connectors in the VCS loop (see tableon following page).

Pin 9 and pin 5 of the BUS-OUT connector must be bridged. No BUS-OUT connector is connected to the last node in theInterbus line.

Description:

The baud rate is fixed at 500 Kbaud. The bus cable is a shielded cable with 3 twisted pairs.The number of input/output data transmitted in the Interbus can be changed with the DIP switch „Size“ (see chapter 2.4.5).

Unlike with other fieldbus systems, only max. 20 bytes can be transmitted in this system. This means that with the "analogicsignal" it is recommended to set a size of max. 7 with the DIP switches. Without "analogic signal" a size of max. 8 isrecommended. All larger settings are limited to the corresponding maximum.

Configuration:

No special configuration required: the size of each node (address space) is automatically recognised and the fieldbusaddress is fixed in compliance with the physical position in the Interbus loop.

Insert the cable as indicated with the arrow (observe themarking on the cable) through the VCS connectors. It ends at the „VCS IN“ terminals. Whenconnecting valve batteries (multiple valve blocks), open all the VCS connectors and insert the cable.Shut the VCS connectors one after the other from the left to the right. This order must be observed to prevent the VCS cable from being crushed.On starting up the system, the LED indicators blink in a certain sequence. In the end only the „RUN“ and „27V“ LEDs lightup green. If this is not the case, errors are indicated by a blinking or constantly lit up LEDs.

6.3 Test mode

Switch off pressure supply, because all coils will be energised during the test mode.

The test mode can be switched on in the two following ways:1. De-energise the VCS loop (switch off all VCS power supplies).

Set the DIP switch TEST to ON and the DIP switch ERR to OFF.Switch on all VCS power supplies.

2. Set the DIP switch TEST to ON and the DIP switch ERR to OFF.Press the Reset test button.

- In this phase of the test, the VCS connectors are switched on in consecutive groups of 8 (1 to 8, then 9 to 16, then 17to 24 etc.) in an activation cycle of 2 seconds for the whole loop.This enables you to check the piloting and function of each VCS connector.

- Check the piece of VCS cable between the last blinking VCS connector and the first VCS connector that does not blink,and check the contacts.

- Replace, if necessary, the first VCS connector that does not blink or the last blinking VCS connector.- Switch on the VCS power supply.- If all VCS connectors blink, set the DIP switch TEST to OFF. The system restarts. The error should be recovered.- In case one or more than one VCS connector does not work, the corresponding VCS cable connections and VCS

connectors must be checked and possibly replaced.

During the operation of the VCS loop, the LEDs also indicate errors in the individual VCS connectors. The following errorscan be reported for each VCS connector: low voltage, overcurrent, overheating. These are group errors, i.e. either one orseveral VCS connectors can be at fault.

- Set the DIP switch TEST to OFF and ERR to ON.- All LEDs (except the 27V-LED) are off.- The kind of error is indicated first (error LED lights up for a short time), and then the number of the faulty VCS connector.

The LED RUN, DATA and >T are used to indicate the number of a VCS connector in the error mode. They have the followingsignificance:

RUN ___________ 100 (hundreds digit)

DATA ___________ 10 (tens digit)

>T ___________ 1 (units digit)

- Count the number of flashes of each LED.- Add up the number of flashes of all LEDs to reveal the number of the faulty VCS connector.

Several VCS connectors having the same error are displayed in ascending order. The flashing rate of each LED must becounted to reveal the connector number of the faulty VCS connector. A maximum of three errors and the correspondingconnector number are indicated.

Up to three pairs (errors and VCS numbers) are shown.

After this display procedure, all group errors are indicated again.

You can repeat the display procedure several times by switching the DIP switch ERR from OFF to ON.

10.5 Pressure supply of pilot valvesA MEGA spool valve is equipped on one side with a spacer sealing which also provides fora selecting function:- The spool valve can be adapted to either internal or external pilot pressure supply simply

by rotating this sealing.- The position selected for each spool valve can be identified from the outside even after

the spool valves have been assembled to islands.- Internal and external pressure supply can be mixed on one island.- If the components are supplied separately, the spool valves are delivered with the sealing

placed in INT for internal pressure supply.

Internal pressure supply to pilot valves External pressure supply to pilot valves

Identification underneath the spool valve

In this configuration:The pilot valves are directly supplied with pressure byusing the supply pressure (1) in the middle of the spool valve.The common pressure supply (spool valve and pilot valves)is 3 to 8 bar (2 to 8 bar with bistable 5/2 spool valves).

In this configuration:- The spool valves on an island can be supplied with low

pressure and vacuum.- The pilots and the spool valves on an island can be supplied

with pressure over 2 separate lines.Supply pressure of pilot valves: 3 to 8 bar(2 to 8 bar with bistable 5/2 spool valves)Supply pressure of spool valves: -0.950 bar to +8 bar.Connection of pilot pressure supply 12/14 at either one of the2 end covers.

INSTALLATION

1 - Screw the two rows of posts (B1) into theLH end-fitting (A) fitting one post in eachrow for each spool valve to be installed(two 18 mm posts are supplied with eachspool valve).

2 - End with two male-male posts on the RHside (supplied with the end-fittings) with theshort threaded end on the post side (C).

3 - Install the RH end-fitting, taking care toproperly seat the seal (J) and pre-tightenwith the two knurled knobs, leaving a playof 2 mm for installing the spool valves.

4 - Identify each spool valve by its label withthe diagram, code, and letter of the type(e.g. S, M, G etc.), then check that theselector seal (J):• is in place,• properly oriented (INT or EXT) for thedesired piloting arrangement (see corre-sponding section), and• properly seated in its housing.

5 - Clip each spool valve (D) to the posts asdescribed in 5a and 5b.

6 - Place the spool valves against each otherbeginning at the LH side.Check that there is enough room and clear-ance to install the last spool valve.Check that all spool valves are properlyclipped on and aligned.

7 - Secure the island assembly by screwingtight with the knurled knobs. Do not usepliers or any other tool!

- Fix the island to the support provided:install on frame with two M4 screws ordirectly to symmetrical DIN EN50022 rail(see chapter 10.4.1).

8 - Identify the type of connector intended forthe MEGA spool valves (see chapters 2.1& 3.1) and install them on the spool valves.

9 - Open all the lids of the connectors on theisland, connect the green VCS cable + the(possible) black power cable, shut the lidsto ensure proper contacting (see chapter 2.3).
