SLC long -range security light curtain performance characteristics

SLC long -range security light curtain is a new type of radio safety product developed and developed by advanced technology. The light curtain itself has high safety. All products have the following advantages

CPU self-check

The SLC light curtain uses CPU self-checking to ensure that the light curt ain does not send an error signal to the controlled device in the event of its own faults (e.g., light source out of sync, insufficient light source inte nsity, faulty light throw driver circuit, faulty main control circuit, faulty cables, and faulty receiver driver circuit).

Dual Independent OSSD Outputs

In the output for the pursuit of better safety, the use of dual independent OSSD outputs, so that the automatic prevention of malfunction with a high degree of security, can be directly driven by relays and security PLC and provides a relay monitoring of high-power loads.

Easy Maintenance

When the light curtain malfunctions, a specific digital tube and indicator light will inform you of the location of the malfunction and the cause of the malfunction, so that you can perform better maintenance.

optical synchronization

Light-synchronized and dedicated optics for high noise immunity - Good resistance to electromagnetic signals, strobe lights, welding arcs, and ambient light sources.

earthquake resistant

With good anti-vibration performance, component welding adopts SMT technology and several anti-vibration measures, which can be applied in different places.

Multi-frame protection

The reflector can be used in conjunction with the camera when the area to be protected is not on the same surface.

Function can not be set

All functions of the SLC Long Distance Safety Light Curtain can be easily set up and maintained via a wireless communicator.

pulse test

Self-diagnosis of the dual output circuitry with very short periodic pulses does not affect the operation) for a forced and instantaneous shutdown (self-generated and self-collected) If a shutdown pulse occurs without feedback, the host computer shuts down the OSSD outputs to ensure safety.

The SLC long-distance safety light curtain has an OSSD output self-diagnostic function. During the normal energization of the OSSD output of the light curtain, the internal control timing control unit of the light curtain periodically and actively turns off the OSSD1 and OSSD2 outputs in sequence. During a short period of time when OSSD1 or OSSD2 is switched off, the light curtain's internal timing control unit detects whether the OSSD1 or OSSD2 level has flipped, and if it has, the corresponding OSSD switch is in normal operation; if the OSSD has not been detected to have flipped, then a fault has been created in the corresponding OSSD, and the system switches off the two OSSDs immediately, with a "d" displayed on the receiving grating digital display. If the OSSD is not detected as having flipped, the corresponding OSSD has failed and the system will immediately shut down both OSSDs, at which point the receiver grating digitizer will display "d." or "H." to ensure functional safety. Therefore, when the load connected to the SLC light curtain is a PLC or a fast intelligent device with MCU control, it is necessary to filter out the self-test pulse in the program. The above figure shows the PNP type light curtain auto-diagnostic output waveform timing diagram.
