SLC-LP Series Safety Light Curtain The Features and Advantage

SLC series light curtain is Type 4 safety light curtain which conformed to international safety standard EN61496-1/2. SLC safety light curtain builds a safe workplace to customers. It iswith the following advantages：

◆ System Failure detection

SLC series of safety light curtain is with CPU self-test function, when their  own failure (such a s the light is not synchronized, the light intensity is not enough, cast li ght 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 use the  two chann el system (connects 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 fee dback signal, if it does not detect the fee dback 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.

◆ Manual Reset/Interlock Function

◆ Floating Shield Fun ction

Preventing the material from moving and blocking the light beam allows  small objects to pass smoothly under the condition of ensuring safety,

improving production efficiency and production safety at the same time. (Set via software).

◆ Fixed Shield Function

For the material staying in the beam for a long time or the optical axis blocked by the workbench is invalid, the optical axis other than the material blocking works normally. (Set via software)

◆ By Pass (Muting) function;

This function cooperates with two external input signals to pass the  difference between people and materials. It can make the material on the line pass through the grating smoothly, while the person passing through is protected.

◆ Short Protection and Over load 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 diff erent 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-saeg ment digital and LED li ght s.

◆ Self- diagnosis

Self- diagnosis is performed on the power up (within 2 seconds) .Self- diagno sis (rea ction time) is performed periodically during normal operation.

Example of SLC Model Type

SLC safety light curtain OSDD

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. The figure above is the timing diagram of the output waveform of the PNP type grating self-diagnosis.
