Description
The SLCS safety light curtain consists of an transmitter and a receiver. The
protection field is formed by infrared light beams sent from the transmitter to the
receiver. The offset between the individual light beams determines the minimum
obstruction size (14, 30, 60 or 90 mm) that can be reliably detected in the entire
protection field range.
The transmitter contains a certain number of transmitter diodes that emit
protective beams. The number of transmitter diodes is determined by the
protection field height and size of the obstacle. The A/B mode function allows the
use of two safety light curtains in close proximity.
The receiver unit detects the transmitted beams, controls the two OSSD safety
outputs and carries out tests to ensure safety.
In addition to the displays behind the front panel of the receiver unit, there is one
pnp output, which indicates operational readiness, a dirty lens, or fault states. If an
internal fault occurs in the receiver unit, this output switches on and off at a
frequency of 5 Hz. If an external fault occurs, this output switches on and off at a
frequency of 1 Hz. If 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 initiates a test sequence. Activate the input by
applying 24 VDC to the input for a defined period of time.
The relay monitor (RM) and restart (RI) inputs allow monitoring of the switching
elements connected externally to the OSSDs and activation of the startup/restart
interlock function.
