safety guidelines are not followed, dangers to personnel can arise that could lead to serious injury or in worst cases, death. In less serious cases, systems and equipment can be damaged. The following symbols identify the individual risks as well as the degree of seriousness and their respective meanings are briefly explained. You should therefore familiarize yourself with the safety symbols and their meanings to prevent dangers and risks early. DANGER! DANGER! Identifies an immediate danger with high risk, which can lead to immediate death or serious injury if not avoided. WARNING WARNING Identifies a possible danger with a mid-level risk, which can lead to death or (serious) injury if not avoi- ded. CAUTION! CAUTION! Identifies a low risk danger, which can lead to injury or property damage if not avoided. 29.07.2013 Page 5 S-DIAS MODULAR SAFETY COMPONENT 1.2 Further Safety Guidelines Warning, dangerous electrical voltage Hot surface warning Danger for ESD-sensitive components This symbol identifies important or additional informa- tion in relation to the operation of the safety modules.

The same applies when the button is released too soon (before LED B lights) or it is pushed immediately after being released (time between 2 button presses shorter than 200 ms). 29.07.2013 Page 17 S-DIAS MODULAR SAFETY COMPONENT 4.5.2 Command Selection Sequence After the Start sequence, the desired command is selected. This selection is made with button presses in the following time intervals: Minimum press duration is 200 ms, maximum is approximately 3 seconds; the minimum pause between individual button presses is 200 ms, the maximum is 10 seconds. After each correct button press (incl. The minimum pause of approx. 200 ms), the selected command is shown with LEDs C1, C2 and C3. If an invalid command is selected (see "valid commands"), the Error sequence is initiated; as with not correctly observing the time intervals. LED B lights continuously during this sequence. 4.5.3 End Sequence This sequence is used to confirm the selected command. Here, the button is pressed until LED starts to blink (approx. 3 seconds, blinks in a slow interval). The number of light pulses in LED B depends on the previously selected command (see "valid commands"). After the LED turns off, the button must be released. After the minimum pause of approxi- mately 200 ms, in which the button must not be pressed, the service mode is imitated and the command is executed. If the button pressed for longer than approximately 3 seconds, the selected command is not accepted and the Error sequence is displayed. The same applies when the button is released too soon or the minimum pause of 200 ms is not observed. After executing the command, the corresponding mode is initiated depending on the com- mand (see "Valid Commands"). If executing the command leads to an error (e.g. because SET_VERIFIED should be exe- cuted although no valid configuration data is available in the Safety CPU), the Error se- quence is initiated. Page 18 29.07.2013 S-DIAS MODULAR SAFETY COMPONENT 4.5.4 Error Sequence If an invalid button press occurs, as in the sequences described above, the Error sequence is initiated. LED B indicates this sequence with fast blinking, which lasts for at least 3 sec- onds. If the button is still pressed after 3 seconds, LED B will continue to blink until the button is released and a minimum pause of approximately 200 ms has elapsed. The Start sequence cannot be reinitiated until LED B stops blinking. After ending the Error sequence, the mode is changed as described in "Overview of Module Statuses". If turned on, LEDs C1, C2 and C3 are turned off after ending the Error sequence. 29.07.2013 Page 19 S-DIAS MODULAR SAFETY COMPONENT 4.6 Overview of Commands The number of button presses corresponds to the number of light pulses in LED B during the End sequence. Commands Number of button LED C1 LED C2 LED C3 presses QUIT_ERROR 1 X CLR_CFG 2 X X SET_VERIFIED 3 X X X 4.7 Overview of Module Statuses and Commands The following tables show a sample of the statuses in which the system can be found, the commands that can be active during the respective status and their functions (see the Safe- ty System handbook for the module statuses). COMMAND System status QUIT_ERROR CLR_CFG SET_VERIFIED Check-Configuration X Time-restricted operational mode X X Operational mode X Service mode X Error X Page 20 29.07.2013 S-DIAS MODULAR SAFETY COMPONENT Executed com- Command function Status after command mand execution QUIT_ERROR A possible error is cancelled in the Safety CPU SW-RESET *) and all safety modules required by the Safety CPU and the error status is ended. CLR_CFG The configuration in the Safety CPU is deleted. Service mode After executing the command, the Safety CPU is now in service mode. SET_VERIFIED The configuration status is set to "verified". Operational mode *) A SW-RESET is performed. If the error still exists, the Safety CPU remains in the error mode. Otherwise, the Safety CPU starts correctly. General note: If a command was entered incorrectly, the Safety CPU initiates the error sequence (see above). After ending the Error sequence, the command can be reentered. 29.07.2013 Page 21 S-DIAS MODULAR SAFETY COMPONENT 4.8 Handling the microSD Card An SD card can only be written on with the Safety Designer. A detailed description can be found in the LASAL SafetyDesigner configuration tools documentation. A Safety project, which was programmed with the SafetyDesigner, can be stored on an SD card. The stored Safety project can then be loaded into an additional SCP Safety-CPU, providing that the module's Flash memory is empty (cleared). If the configuration on the SD card is different from that on the Safety CPU Flash, the sys- tem switches to the error status (error message 87). The SD card cannot be inserted into the Safety CPU during normal operation (Operational or temporary operational mode). If the SD card is inserted during normal operation, the Safety CPU switches to the error status (error message 88). However, an SD card can be removed during normal operation. Page 22 29.07.2013 S-DIAS MODULAR SAFETY COMPONENT 4.9 Configuring a Safety CPU with the SD Card The configuration is loaded from an SD card a follows: • Delete the configuration of the Safety CPU to be programmed To load the configuration from the SD card, the configuration in the Safety CPU must first be deleted. This can be done with either the SafetyDesigner or with help from the CLR_CFG command using validation button on the Safety CPU. Once the configuration in the Safety CPU is deleted, it can no longer return to the operational or temporary operational mode. The Safety CPU freezes in the service mode. • Insert the SD card and deactivate the system In the next step, an SD card with the valid configuration must be inserted in the Safety CPU and the system shut down. • Restart the system with the SD card When the system is restarted, the configuration is loaded from the SD card into the Flash of the Safety CPU. This is only possible if a valid configuration is sto- red on the SD card. If the SD card has an incorrect format (error message 86) or the Safety CPU's Flash has not been cleared (error message 87), the Safety CPU goes into the error status. If the configuration does not match the avail- able real modules, the distribution process of the configuration triggers an error (error message 9) and the Safety CPU also goes into safe mode. • If an error occurs during the restart, see the following chapter " Restart Error". A micro SD card with a memory capacity of 1 Gigabyte is available from SIGMATEK under the article number 12-630-101 Only micro SD cards that support version 2.0 or higher of the "SDA Physical Layer Specification" (SDA=SD Card Association) can be used. 29.07.2013 Page 23 S-DIAS MODULAR SAFETY COMPONENT 5 Error Response In the event of an error, please consult the chapter "LED Displays", as important information on the runtime status of the system can be derived from the status an error display. Since errors in general are of a complex nature, do not perform a diagnosis based on the LEDs alone (consult the corresponding chapter in the Safety System Handbook as well). For an exact error analysis, the SafetyDesigner must be used. 5.1 Restart Errors The following diagram shows the response of the Safety CPU module during restart. Flash Flash Restart Wiederanlauf Safe- Service Safe-CPU POST Cpu is Mode ist leer a) Empty Error Konfiguration nicht Mode Configuration not distribu- verteilt ted Idle Check Config. Mode dauerhaft ON Continously on dauerhaft ON Continously on blinking blinken Digital Input Configuration distributed Konfiguration verteilt E Digital Input ST Internal logic 1 to 10 dauerhaft ON (Temp.) Continously on Op. Mode Continou dauerhaf sly t O on N RN Page 24 29.07.2013 S-DIAS MODULAR SAFETY COMPONENT During restart, the Safety CPU first runs the POST (Power On Self Test). In the POST, whether the Safety CPU is configured or not is determined. If the Flash memory in the Safety CPU is empty, it changes to the service mode and switches the status LED (ST) to continuously on. b) If the Flash memory of the Safety CPU contains a configuration, it goes into the idle / Check Configuration Mode. Thereby, an attempt is made to distribute the configuration; the ST-LED blinks during this process. c) If the configuration is successfully distributed, the Safety CPU either goes into the Operational mode or the Temporary Operational mode depending on whether or not the configuration has already been validated. If the System was already vali- dated, the ST-LED turns off and the RN-LED lights. If the system has not been validated, both LEDs light simultaneously. d) If for whatever reason the distribution of the configuration is still not successful, the Safety CPU switches to the Error mode and the E-LED lights e) When the Safety CPU remains in the idle / Check Configuration Mode for a long period of time (ST-LED blinking) without switching to the Error mode, it is an indi- cation that the bus communication is malfunctioning. In this case, the PLC will re- main in the error status and must be restarted. f) A change to the error status can also occur from the POST and (Temp.) OP mode if other (internal) errors are detected or errors in remote modules occur. The analysis of these errors however, requires the use of the SafetyDesigner. 5.2 Configuration distribution error If the Safety CPU fails to distribute the configuration, the cause can be traced to one or more of the following errors. • The configuration and the physical topology do not match • One or more modules are missing • More than one module was exchanged • Communication error with a remote module • The module to be configured is in error status 29.07.2013 Page 25 S-DIAS MODULAR SAFETY COMPONENT 5.3 Troubleshooting • Check all modules in the system for completeness and Type conformity • Check that all modules are error-free • Check all connector cables • Cancel the error with the QUIT_ERROR command If the Safety CPU remains in the error status after the QUIT_ERROR command has been executed, it must be retested using the SafetyDesigner. 5.4 Troubleshooting with the SafetyDesigner Connect the SafetyDesigner Debug the system using the SafetyDesigner. 5.5 Correcting a wiring error When a wiring error is determined, a controlled deactivation of the sys- tem is required, which must then be turned off. The system can only be rewired when no power is applied. Page 26 29.07.2013 S-DIAS MODULAR SAFETY COMPONENT 6 SDI 100 29.07.2013 Page 27 S-DIAS MODULAR SAFETY COMPONENT Test Signals for Cross-Circuit Detection The module sends pulses in cyclic time intervals to detect a crossed circuit in the outputs. When selecting the actuators, keep in mind that these pulses do not activate the actuators or trigger any diagnostic messages. The pulse sig- nals cannot be deactivated or configured. Cross-Circuit Detection It is important to keep in mind that the cross-circuit detection only functions cor- rectly when it is configured and wired correctly. This applies equally to in- and outputs.

The DIN rail must provide a conductive connection to the rear wall of the control cabinet. The individual modules are mounted on the DIN rail as a block and locked with the latch. The modules can only be mounted verti- cally (module label on top) with sufficient clearance for the ventilation slots between com- ponents or control cabinet wall. This is required for optimal cooling and air circulation and to ensure functionality at the maximum operating temperature. 29.07.2013 Page 41 S-DIAS MODULAR SAFETY COMPONENT 11 Status Displays The Safety module has general status displays (LEDs) which indicate the operating mode and the status of the power supply. The status of the individual in and outputs are indicated by LEDs directly on the connector in green or yellow.
