28 2. Fitting Contents 2. Fitting Mounting the valve terminal Installing a valve in a vacant valve location Installation of additional components Earthing the end plates Wall mounting the valve terminal Rear side mounting

29 2. Fitting 2.1 Mounting the valve terminal Please note Valve terminal with two pressure zones: The terminal can be ordered from the factory with a two pressure zone design. To see if your terminal has two pressure zones, check the order documentation for the terminal. Subsequent conversion to two pressure zones can only be implemented by Festo Service. Warning Switch off the following before undertaking mounting work: the compressed air supply the operating voltage supply for the electronics (pin 1) the load voltage supply for the outputs/valves (pin 2). You can thereby avoid: uncontrolled movements of loose tubing unexpected movements of the connected actuators non-defined switching states of the electronic components. Caution Electrostatically sensitive components. Do not touch any contact surfaces on the lateral plug connectors of the modules and components. Observe the regulations for handling electrostatically sensitive components. You will then prevent the valve terminal module from being damaged. 2-3

30 2. Fitting The valve terminal is delivered fully assembled from the factory. If you wish to add or replace individual modules and components, please note the following manuals: For installing electric IO modules - Supplementary manual for IO modules. For installing the nodes - Electronics manual. For modules and components ordered at a later date, see the installation instructions in the accompanying product leaflet. Please note Handle the modules and components of the valve terminal carefully. Pay particular attention to the following: tighten screws without warping or mechanical stress correct positioning of the screws (otherwise danger of damaging the threads) maintain the specified torque avoid offset between modules (IP65) clean contact surfaces (avoidance of leakages and contact faults) close vacant valve locations with the appropriate cover plate (to be ordered separately). The screwed on terminal must be removed to extend or modify the valve terminal. Proceed as follows: switch off the power and compressed air supply for the terminal remove the terminal from the connection surfaces and place it on a flat surface clean the valve terminal before removing the components to prevent dirt from entering the air ducts of the components. 2-4

31 2. Fitting Installing a valve in a vacant valve location Please note You will require the appropriate solenoid intermediate plate when installing a single-solenoid valve with spring resetting, a single-solenoid valve with pneumatic spring or adoublepilotvalve. Vacant valve locations are sealed with cover plates. This ensures the following: the empty spaces of the sub-base are protected against dirt pressure sealed closure of the valve and coil connection levels. Removing the cover plate Undo the screws on the cover plate of the relevant valve location and remove the cover plate from the sub-base. Installing the valve 1. Fit new seals. 2. Screw the 4 stud bolts provided into the fixing bores of the sub-base. 3. Place the solenoid intermediate plate on the sub-base. 2-5

32 2. Fitting 4. Position any additional components on the solenoid intermediate plate and screw the components on firmly. 5. Fasten the valve ISO valve 2 If required, insert vertical linking components here 3 Solenoid intermediate plate 4 Sub-base Fig. 2/1: Installing the valve 2-6

33 2. Fitting Installation of additional components Decide where the additional component is to be inserted. Fig. 2/2: Installation of additional components Removing components 1. Undo the screws of all components above the relevant location. 2. Remove the components. Installing new components 1. Fit new seals. 2. Position the new component on the solenoid intermediate plate or if necessary on a previously fitted component. 3. Fasten the new component. 4. Install the previously removed components in the same manner as before. 2-7

34 2. Fitting Earthing the end plates The valve terminal is fitted with left and right end plates to mechanically close the terminal. These end plates carry out the following functions: they ensure protection class IP65 they include connections/bores for the protective earthing (left end plate only) they include bores for wall mounting (ISO size 1 only) Warning The right end plate must be earthed before assembly! This will prevent high voltages on the metal surfaces in cases of faults. Right end plate This is conductively connected by metal screws to the linking plate. Left end plate This is conductively connected by pre-assembled spring contacts with the other components. Please note Notes regarding earthing of the entire valve terminal can befound in the Electronics manual, Installation chapter, of the valve terminal. 2-8

35 2. Fitting 2.2 Wall mounting the valve terminal Caution Use additional angle brackets for the modules (ca. every 200 mm) for longer terminals with several IO modules. You can thereby avoid: overloading the fixing eyes on the left end plate sagging of the terminal (IO side) self-resonances. Proceed as follows: 1. determine the weight of the terminal (weigh or calculate). Reference values: Determining the weight of the valve terminal Size 1 Size 2 Size 3 Per node 1.0 kg 1.0 kg 1.0 kg Per electric module 0.4 kg 0.4 kg 0.4 kg Adapter plate, right and left end plates Per sub-base including solenoid intermediate plate and valve 3.0 kg 3.2 kg 4.1 kg 1.2 kg 1.6 kg 2.4 kg Fig. 2/3: Weights of the valve terminal components 2. Ensure that your mounting surface can support this weight. Check whether angle brackets are required for the IO modules. 3. Mount the terminal in compliance with the following table. If necessary, use washers. The terminal can be installed in any position. 2-9

36 2. Fitting Type of terminal Type 04-B Mounting options withtwom6 screwsonthe left endplate with M6 screws (ISO size 1 and 2) or M8 screws (ISO size 3) for the adapter plate, the sub-bases and the right end plate. Where necessary, use the following additional mounting options: bores ( blind holes ) on the bottom of the sub-bases. additional angle brackets for the modules in terminals with several IO modules (ca. every 200 mm, see mounting instructions in the product leaflet of the angle brackets). Fig. 2/4: Mounting options for wall mounting 2-10

37 2. Fitting Rear side mounting Bores (blind holes) are located on the rear side of the subbases to mount the terminal on machines or metal racks (rear side mounting). Threaded bolts must be cut for this purpose (ISO size 1: M5; ISO size 2: M6; ISO size 3: M8). All the above steps also apply in this case (see also the following diagram). 1 1 Blind hole Fig. 2/5: Blind hole for rear side mounting (diagram of sub-base ISO size 2) 2-11

41 3. Installation 3.1 General connection methods Warning Before carrying out installation or maintenance work, switch off the following: the compressed air supply the operating voltage supply for the electronics (pin 1) the load voltage supply for the outputs (pin 2). You can thereby avoid: uncontrolled movements of loose tubing unexpected movements of the connected actuators non-defined switching states of the electronic components Laying thetubing Caution Place a suitable seal under each screw connector or silencer in order to avoid leakage. If elbow screw connectors or multiple distributors are used, the airflow will be reduced slightly. 3-3

42 3. Installation Basic information Connecting 1. Push the tubing as far as possible over or into the tube connection of the screw connector. 2. If necessary, pull the locking ring over the tube connection or tighten the screw connector. 3. For reasons of clarity, group the tubing together with tube straps or multiple tube connector blocks. Removing 1. If necessary, loosen the locking screw or locking ring of the screw connector. 2. Pull out the tubing. 3. If necessary, replace the screw connectors with blind plugs. 3-4

43 3. Installation 3.2 Connecting the valve terminal Preparing the sub-base Connections are available on the right end plate as well as on the top of the adapter plate. The common lines can therefore be connected as required on the left, right or both sides. In operations with two pressure zones, each side must be separately supplied with pressure. In order to guarantee the optimum efficiency of your valve terminal, we recommend in the following cases that you connect the compressed air tubing and, if necessary, also the exhaust air tubing: when large volume cylinders are operated at high speeds with basic operation cylinders when using terminals with more than 8 valves. 3-5

44 3. Installation Prepare the connections as follows: 1 Right end plate 2 Connections for common tubing Connectionofcommontubing Only on adapter plate or only on right end plate Onthe adapterplate and right end plate Procedure Remove all adhesive film; insert blind plugs in adapter plate or right end plate (to be ordered separately) Remove all adhesive film Fig. 3/1: Supply connections on the adapter plate and right end plate 3-6

48 3. Installation Auxiliary pilot air The valve terminal type 04-B is, dependent on your order, set to internal or external auxiliary pilot air. Internal pilot air When the supply pressure of the valve terminal is within the range of 3 to 10 bar, it can be operated with internal pilot air. The auxiliary pilot air is branched off from connection P1. If the valve is set up for internal pilot air, a stopping plug is located in each of the air ducts 12 and 14 on the underside of the solenoid intermediate plate (see Fig. 3/5). the arrow of the code seal on the pneumatic spring side points to P (see Fig. 3/6) External pilot air When the supply pressure of the valve terminal is not within therangeof3to10bar,itmustbeoperatedwithexternal pilot air. The external auxiliary pilot air is fed in through connections 12 and 14 on the right end plate. If the valve is set up for external pilot air, a stopping plug is located in air duct P1 on the underside of the solenoid intermediate plate (see Fig. 3/5). The flow from P1 to the auxiliary pilot air ducts is thereby blocked. the arrow of the code seal on the pneumatic spring side points to S (see Fig. 3/6). 3-10

49 3. Installation Please note Only use pressure-controlled auxiliary pilot air. This permits reliable, problem-free operation of the valve terminal. It must be ensured that pressure-controlled auxiliary pilot air is fed or branched off from only one point to the common lines for all pneumatic components. This also applies if the valve terminal is operated with two pressure zones Conversion from internal to external auxiliary pilot air Warning Switch off the compressed air supply before beginning the conversion. Conversion from internal to external pilot air can be implemented regardless of the valve terminal design. Proceed as follows: change the position of the stopping pin on the underside of the solenoid intermediate plate (see Fig. 3/5) for valves with pneumatic spring: rotate the code seal on thespringsideofthevalve(seefig.3/6) for external pilot air: connect the auxiliary pilot air supply to connections 12 and 14 on the right end plate. For internal pilot air: the connections 12 and 14 on the right end plate must be closed with blind plugs (to be ordered separately). 3-11

54 4. Commissioning Contents 4. Commissioning Commissioning tests Checking the valve functions Checking the valve-cylinder combination Error diagnosis Impairment of function LED displays of the valves Troubleshooting Replacing the valve solenoid coil fuse

55 4. Commissioning 4.1 Commissioning tests The following procedures are recommended when commissioning the valve terminal: Commissioning variants Pre-testing the pneumatic hose lines Full commissioning of the complete system Measures Moving the valve-cylinder-combination by means of the manual override (MO) Installing and connecting the complete system (all fieldbus slaves). Program control using PLC/industrial PC Fig. 4/1: Commissioning variants Commissioning with MO is described below. Program controlled commissioning is described in the manual for the relevant node. 4-3

56 4. Commissioning Checking the valve functions Manual override (MO) Warning Only use the MO when the valves are in a voltage-free state. Before actuating the electronic signals: Ensure that all MO are reset to the start position. The MO is mainly used during commissioning of the pneumatic system to check the function and operation of the valve or the valve-cylinder combination. The MO is used to switch the valve without an electric signal. You only need to switch on the compressed air supply. 4-4

57 4. Commissioning Types of manual override The MO is designed for the following uses: MO type MO with automatic return (non-locking) Method of operation After actuation, the MO is reset by spring force. Fig. 4/2: MO type 1 1 Non-locking manual override Fig. 4/3: Position of the MO 4-5

58 4. Commissioning Checking the valve-cylinder combination Warning When pressurizing or re-pressurizing the valve terminal under the following conditions: using a safety switch-on valve (slow pressurizing) and with existing electric signals (e.g.followinganemergencystop). The auxiliary pilot air must reach full pressure immediately after being switched on, otherwise the slow build-up in pressure of the complete supply will have no effect on the cylinders: activated by the mid-position valve exhausted in the normal position activated by the mid-position valve blocked in the normal position activated by single-solenoid valves activated by double-solenoid valves which are switched to flow position during the pressureless phase. Separately supplied auxiliary pilot air Pressure increase of complete supply Pressure increase in the auxiliary pilot air (12,14) Switching time of a valve Movement of the cylinder With regulator Slowly Slowly After pressure increase with (1) Fast Without regulator Slowly Fast Before pressure increase with (1) Slowly Fig. 4/4: Effects of slow switch-on pressurization with existing electric signals 4-6

59 4. Commissioning Execution of test 1. Switch on the compressed air supply. 2. Check the function and operation of each individual valvecylinder combination by actuating the manual override as shown in the following diagrams. 3. Switch off the compressed air supply. Actuation of MO with automatic return (non-locking) Push the MO piston in as far as possible Reaction of the valve The valve: switches Hold the piston down Release the piston. The spring resets the piston of the MO to the normal position. remains switched returns to the normal position Fig. 4/5: MO with automatic return 4-7

60 4.

72 A. Technical appendix A.2 Manual valve terminal configuration type 04-B The valve terminal type 04-B is set up at the factory for automatic address assignment. This is described in detail in the Electronics manual (type 03/04-B). The settings can be altered at a later date using the DIL switches. The manual valve terminal configuration is described below. Caution Manual modification of the valve terminal configuration may affect the control of the connected actuators. This intervention causes the following changes: the calculation for the number of outputs is changed the configuration of the terminal on the bus is correspondingly changed (dependent on the protocol) the addressing of the output modules starts at a precisely defined address limited address space is available for additionally mounted valves in expansion/conversion work unpermitted settings on the DIL switch may trigger error messages These possible effects are not taken into account in the Electronics manual type 03/04-B of the node. Pay careful attention, therefore, to the instructions and notes in the following sections. A-8

73 A. Technical appendix A.2.1 Differences between automatic/manual valve terminal configuration Automatic Configuration The valve is set to automatic address assignment at the factory ( valves). During initialisation, the valve terminal detects all valves during automatic configuration and assigns the addresses according to the basic rules (see the Electronics manual of the valve terminal). Additional output stages are addressed with reference to the (rounded 4 bit) valve addresses. If valve locations are added at a later date, the output addresses are shifted accordingly. Manual In manual configuration, the size of the valve address area does not change during expansion/conversion of the valves as long as sufficient address space was initially reserved for the expansion. In this case, the addresses of the electric outputs are not shifted. Manual pre-setting of the valve address area is implemented with the DIL switch module located under the cover of the adapter plate. Warning Changes to the DIL switch settings will cause changes to the digital output addressing when the valve terminal is started up! A-9

74 A. Technical appendix A.2.2 Manual configuration procedure Caution Before starting any configuration procedures, switch off the following: the compressed air supply the operating voltage supply for the electronics (pin 1 of the power supply plug) the load voltage supply for the outputs/valves (pin 2 of the power supply plug). You can thereby avoid: uncontrolled movements of loose tubing unexpected movements of the connected actuators non-defined switching states of the electronic components. Please note The cover on the adapter plate is connected via the power supply cable to the circuit boards within and should therefore not be completely removed. Proceed as follows: 1. undo and remove the four Phillips screws on the cover. Carefully raise the cover and ensure that the cable is not damaged by pulling, bending or twisting. A-10

75 A. Technical appendix M4 x 12 Fig. A/1: Removing the cover of the adapter plate 2. Use a suitable tool to set the DIL switch, e.g. a pen. Set the DIL switch elements in accordance with the following table. Four valve outputs correspond to each DIL switch element. Fig. A/2: Setting the DIL switch A-11

77 A. Technical appendix 3. Replace the cover on the adapter plate and insert the power supply cable back into the housing. Ensure that it cannot be damaged when fastening down the cover. Screw in the four Phillips screws and tighten them in diagonally opposite sequence. Please note The modifications to the manual configuration will only become effective after the operating voltage is switched on again. A-13

78 A. Technical appendix A.2.3 Notes regarding configuration Valve terminal expansion and DIL switch settings The number of connected valves is greater that the number of addresses assigned with the DIL switches Effect The settings of the DIL switch are not applicable. The addresses of the valves and electric outputs will be assigned automatically. OPEN The number of addresses assigned with the DIL switches is greater that the number of valves actually connected OPEN The assigned address area is greater than the number of the valve solenoid coils actually present in the valve terminal. These addresses can be used during a modification or expan- sion of the valve terminal. In this case, the addresses of the electric outputs are not shifted.
