LCM series miniature safety light curtain

LCS series safety grating is a new type of through-beam safety photoelectric protection device developed and developed using the current international advanced technology. The smallest cross-section in the industry is 15×15mm. It has the characteristics of high safety and high reliability through ISO13849-1 PLe and EN61496-1/2 Type4 certification. At the same time, the structure is compact and the shape is slender, and it can achieve single-end without blind spots. Professional optical design and circuit design make the safety grating have very good resistance to electromagnetic interference and ambient light interference, so it can be used in many harsh environments and structurally restricted areas.

This grating has the following characteristics:

LCS series miniature safety light grid OSDD output self-diagnosis sequence

LCS series miniature safety light grid has OSSD output self-diagnosis function. During the normal light-passing OSSD output of the grating, the internal control timing control unit of the grating periodically and actively turns off the outputs of OSSD1 and OSSD2 in turn. When OSSD1 or OSSD2 is closed for a short time, the internal timing control unit of the grating detects whether the level of OSSD1 or OSSD2 is consistent with the expected result. If it is consistent, the OSSD switch is in normal working state; if it is inconsistent with the expected result, the OSSD In the event of a failure, the system will immediately shut down the two OSSDs to ensure functional safety. At this time, the red LED indicator light of the receiving grating will flash to indicate the failure. Therefore, when the load connected to the LCS safety light grid is a PLC or a fast intelligent device with MCU control, it is necessary to filter out the self-checking pulse (recommended 1ms) in the program to prevent the PLC or MCU from detecting this waveform and causing the machine to stop. The figure below is the timing chart of the output waveform of the PNP-type grating self-diagnosis

LCS series miniature safety grating back mounting bracket installation method

①Hook the bracket bottom hook into the groove on the upper edge of the grating shell, and stick to the grating shell;

②Hook the hook of the bracket pressing plate into the groove on the other side of the grating shell, close the grating shell, and insert the lower two bosses into the corresponding holes of the bracket bottom plate; 

③Use the matching M4 screws to fasten the bracket pressing plate It is firmly locked with the bottom plate of the rack;

④Finally, use the self-provided M4 or M3 screws and matching M4 plastic gaskets to fix the installed grating and bracket components to the use environment through the two Φ4.3 holes in the bracket bottom plate.
