3 Product Description

3.1 Use and Application

Product description

The SLCS safety light curtain is noncontact electro-sensitive protective equipment

(ESPE) for securing danger zones and hazardous areas.

The SLCT safety light curtain consists of a transmitter unit and receiver unit. The

protection field is formed by infrared light beams sent from the transmitter unit to

the receiver unit. The offset between the individual light beams determines the

minimum obstacle size (14 mm, 30 mm, 60 mm, or 90 mm) that can be reliably

detected in the entire protection field range.

The transmitter unit contains a certain number of transmitter diodes that emit

protective beams. The number of transmitter diodes is determined by the

protection field height and the size of the obstacle. The function mode A/B

enables the use of 2 adjacent safety light curtains.

The receiver unit detects the transmission beams, controls the two OSSD (Output

Signal Switching Devices) safety outputs and carries out tests to ensure safety.

n addition to the displays behind the front panel of the receiver unit, there is also a

PNP output, which indicates operational readiness, a dirty lens, or fault states. f

an internal fault occurs in the receiver unit, this output switches on and off at a

frequency of 5 Hz. f an external fault occurs, this output switches on and off at a

frequency of 1 Hz. f the received signal is too weak (e.g., due to a dirty lens), the

output switches on and off at a frequency of 2.5 Hz.

The test input on the transmitter unit initiates a test sequence. Activate the input by

applying 24 VDC to the input for a defined time span.

The relay monitor (RM) and restart (R ) inputs allow monitoring of the switching

elements connected externally to the OSSDs and activation of the startup/restart

interlock function.
