Installation CPV-DI02 and CPV-CS02 1.5.2 Selecting the power unit Warning In order to provide the electric power supply, use only PELV circuits as per IEC/DIN EN 60204-1 (Protective Extra-Low Voltage, PELV). Take into account also the general requirements for PELV circuits as per IEC/DIN EN 60204-1. Use only power packswhich guarantee reliable electrical isolation of the operating voltage as per IEC/DIN EN 60204-1. By the use of PELV power units, protection against electric shock (protection against direct and indirect contact) is guaranteed in accordance with IEC/DIN EN 60204-1 (electrical equipment of machines, general requirements). The current requirement of a CP system depends on the number of CP modules and valve coils. Recommendation: Use closed-loop controlled power units. When selecting the power unit, check that it provides sufficient output. If necessary, calculate the total current requirement according to the following table. 1-27

1. Installation CPV-DI02 and CPV-CS02 1.5.3 Connecting the power supply Warning If the valve terminal is supplied with load voltage via an output of a safety I/O module, switch-on test pulses of the safety I/O module may lead to unexpected reactions of the valve terminal. Make sure that switch-on test pulses are reliably suppressed or switched off. Power is supplied via a 4-pin M12 plug (see Fig. 1/1). Current consumption depends on the type of valve terminal. Please refer to the Pneumatics manual, P.BE-CPV-... and the previous section for the values. Observe the tolerance with the connection for the 24 V load voltage at pin 2: DC 20.4 26.4 V DC. Check the 24 V operating voltage of the valves whilst the system is operating. Caution Protect the load voltage of the CPV valve coils with a max. 2 A external fuse. In this way you can avoid functional damage to the CPV Direct in the event of a short circuit. 1-29

1. Installation CPV-DI02 and CPV-CS02 1.7 Preparing the CPI system for commissioning This section is only relevant for you if you have connected CPI/CP modules to the CPI extension connection. Note Do not yet connect the CPV Direct to a higher-order controller for preparing commissioning. You will thus avoid addressing faults which may occur in variousfieldbussystemswhenaddressrangesaremodified during operation. 1.7.1 Checking the CP strings Preparations Before commissioning a CPV Direct with CPI extensions, you should first prepare each individual CPI system for commissioning. Proceed as follows: 1. Check the pneumatic tubing of the valve terminals with the aid of the manual override (see pneumatics manual). 2. Check the complete electric circuitry of the CPI system. 3. Save the current string assignment of the CPI system as the nominal assignment, as described in section 1.7.2. 1-38
1. Installation CPV-DI02 and CPV-CS02 1.7.2 Saving the string assignment Warning Be very careful if the string assignment of your CPI system is modified at a later stage: After saving the string assignment, check the address assignments of your CPI system before starting user programs. You will then avoid addressing faults in the case of incorrectly fitted CPI modules. String assignment The CPV Direct saves the type and the sequence of the connected CPI modules for the CP string (string assignment). The saved string assignment enables the CPV Direct to avoid faults in connecting, and thus addresssing. It checks automatically to see if the current string assignment is the same as the saved assignment. A distinction is made here between the following test phases: testing during the start-up phase (see section 1.8) testing during operation (see section 1.9). When the status LEDs on all the CPI modules light up, the CPI system is prepared for commissioning. You can now commission the CPI system. 1-39
1. Installation CPV-DI02 and CPV-CS02 Saving the string assignment The desired string assignment is generated and saved for commissioning. In this way the appropriate addresses are assigned to the connected CPI modules. Save the string assignments as follows: 1. Leave the power supply for the CPV Direct switched off for thetimebeing. 2. Make sure that the CPI cables are fastened properly with the union nut. 3. Switch on the power supply for the CPV Direct and, if necessary, for the CPI/CP modules with load voltage connection. The fault LED P on the CPV Direct will flash if CPI/CP modules are connected or if the string assignment is modified. 4. Use a small screwdriver or similar tool to press the SAVE button for at least 1 s (see section Fig. 1/3). This will save the current string assignment as the nominal string assignment in the CPV Direct. The fault LED Pno longer flashes. The status LEDs of all the recognized CPI/CP modules light up. 5. Power / Note After saving the string assignment, check the address assignments of your CPI system before starting user programs. 1-40
1. Installation CPV-DI02 and CPV-CS02 1.8 Switching-on reaction of the CPI system When the power supply is switched on, the CPV Direct ascertains automatically the current string assignment. It also ascertains which CPI/CP modules are connected to the string extension. If the current assignment is the same as the saved assignment, the CPV Direct will switch automatically to the readyto-operate status. The PS/PL LEDs of the CPV Direct as well as the status LEDs on the connected CPI/CP modules light up. If the current assignment is not the same as the saved assignment, the fault LED P on the CPV Direct will flash. In this case the CPI system is not ready to operate. You then have the following possibilities of restoring the readiness to operate: eliminate assignment faults manually or replace individual CPI modules (see section 1.9) save the current assignment as the nominal assignment (see section 1.7.2). Detailed instructions on diagnosing the CPV Direct using the LEDs can be found in section 3.1. 1-41

1. Installation CPV-DI02 and CPV-CS02 1.9 ReactionoftheCPIsystemtofaultsinoperation Warning Undesired activation of actuators An incorrect status of the valves and outputs can lead to dangerous situations. Make sure that valves and outputs are put into a safe state when faults occur. If there is a fault on the CP string during operation, e.g. due to cable fracture, etc., this will be displayed on the CPV Direct by the diagnostic LED of the string extension (P). The status LED on the relevant module goes out. All modules working without faults remain ready to operate. Detailed instructions on diagnosing the CPV Direct using the LEDs can be found in section 3.1. 1.9.1 Eliminating assignment faults In order to eliminate assignment or connection faults of the CPI system: 1. Switch off the power supply for the CPV Direct. 2. Restore the saved assignment by connecting the appropriate CPI/CP modules with the CPV Direct. 3. Switch on the power supply for the CPV Direct again. 1-43
1. Installation CPV-DI02 and CPV-CS02 1.9.2 Replacing CPI/CP modules Note Replacing a CPI/CP module with a CPI/CP module of a different type or replacing several CPI/CP modules will require new commissioning and new saving of the string assignment (see section 1.7). In order to replace a single CP module, proceed as follows: 1. Switch off the power supply for the CPV Direct. 2. In the case of CPI/CP output modules and valve terminals on the CP string concerned: switch off the following sources of energy: the compressed air supply to the valve terminal the operating voltage supply for the CPI/CP output module. 3. Disconnect all connecting cables and, if necessary, also the tubing. 4. Connect all the cables and, if applicable, the tubing with the new module ofthesametype. 5. Now connect the new module ofthesametypeto the same string. 6. In the case of CPI/CP output modules and CP valve terminals: switch on the operating voltage supply or the compressed air supply again. 7. Switch on the power supply for the CPV Direct again. 8. Check the addresses of the CPI system. 1-44

Caution Communication via the PROFIBUS-DP will start in any case, even if the addresses are used incorrectly. The system does not check in the tool change configuration which modules are actually connected. After changing the string assignment, evaluation of input signals can appear to be defective if inputs are read which are no longer present in the string assignment. After changing the string assignment (e.g. with fewer modules): Ensure that only the addresses of the modules actually connected to the CP string are processed by the controller. The same applies to outputs. Note the example in Tab. 2/8.

3. Diagnosis CPV-DI02 (PROFIBUS-DP) 3.3 Fault treatment With the following faults, the reaction of the CPI system depends on the configured reaction of the master module: telegram failure master stop interruption in the bus cable. Depending on the setting or configuration, all the outputs (valves and electric outputs) will be switched off or retain their status. Warning Make sure that valves and outputs are put into a safe state if the faults named occur. An incorrect status of the valves and outputs can lead to dangerous situations. Note Pleasenotethefollowingiftheoutputsareresetafter PLC stop, field bus interruption or fault: Single-solenoid valves move to the basic position. Double-solenoid valves remain in the current position. Mid-position valves move to the mid-position (depending on valve type: pressurized, exhausted or blocked). 3-20
3. Diagnosis CPV-DI02 (PROFIBUS-DP) 3.3.1 Siemens SIMATIC S7 With these controllers, you can determine the reaction of the CPI system to the faults named above. Almost all configuration programs contain the function Response monitoring. For the operating modes named, the specified time corresponds to the drop-out time of the valves and electric outputs. You can set two types of fault reactions of the control system: Hard fault reaction: the controller switches to the operating mode STOP when a fault occurs. Soft fault reaction: the controller remains in the operating mode RUN when a fault occurs.
