SLC series light curtain is Type 4 safety light curtain which conformed to international safety standard EN61496-1/2. SLC safety light curtain build s a safe workplace to customers. It is with the following advantages:
◆ System Failure detection
SLC series of safety light curtain is with CPU self-test function, when their own failure (such as the light is not synchronized, the light intensity is not enough, cast light drive circuit error, the main control circuit error, cable problems, and receive drive circuit error, CPU error) to ensure that the equipment is not issued to the wrong status, to ensure product safety.
◆ Independent double OSSD output
In order to meet the requirements of the safety standard, please u se the two chann el system ( conn ects the two OSSD independently) connection (the dual redundant system will improve the safety performance). System can drive safety Relay or PLC directly.
◆ OSSD Self- diagnosis
The independent dual OSSD circuit has a self-diagnosis function, which system will close the OSSD output periodically in a very short time (does not affect the work) ,and simultaneously check the feedback signal if it does not detect the feedback signal , will stop the output.
◆ External Device Monitor (EDM)
The SLC safety light curtain monitors the "external relay contact status" in case contact adhesion. System will stop OSSD when detect the error EDM signal to prevent the external relay contact adhesion.
◆ Short Protection and Overload Protection
When the safety light curtain output will turn off the output due to overload or short circuit.
◆ Modulation Frequency
Adjacent light curtain s can be set to different frequencies thus preventing interference with the same frequency.
◆ Anti-light interference and environmental adaptability
◆ Fast Response
The response time of all safety light curtains is within 23ms.
◆ Easy Maintain
Easy to get the status or figure out the problem of the SLC safety light curtain by observing the indication of the 7-saegment digital and LED lights.
◆ Self- diagnosis
Self- diagnosis is performed on the power up (within 2 seconds) .Self- diagnosis (reaction time) is performed periodically during normal operation.



There are self-diagnosis in OSSDs output of SLC safety light curtain. OSSDs will be turn on when the protection area is clear. during OSSDs turned on period, the controller of SLC will periodically shuts down OSSD1 and OSSD2 in sequence.During the short period of shutdown of OSSD1 or OSSD2, the internal timing control unit of the SLC detects whether the level of OSSD1 or OSSD2 has flipped. If the flip occurs, the corresponding OSSD switch is in normal working state; If the OSSD fails, the system will immediately shut down the two channel s of OSSD. At this time, the receiving SLC displays "d." Or "H." to ensure functional safety. Therefore when the load connected to the SLC is a PLC or an MCU controlled fast intelligent device it is necessary to filter the self-check pulse in the program.
