SICK deTec4 User Manual

the K1 and K2 contactors on. When the protective field is interrupted, the OSSD
1 and O
SSD 2 outputs switch the RLY3-OSSD2 off. Lamp H1 lights up. Contactors
K1 and K2 are switched off. As soon as the protective field is clear again, lamp H2
flashes.

F
ault analysis
Cross-circuits and short-circuits of the OSSDs are recognized and lead to the
loc
king status (lock-out). A malfunction with one of the K1 or K2 contactors is
detected. The switch-off function is retained. In the event of manipulation (e.g.,
jamming) of the S1 pushbutton, the RLY3-OSSD2 will not re-enable the output
current circuits.

1) Output circuits. These contacts must be incorporated into the control such that the
d
angerous state is brought to an end if the output circuit is open. For categories 4 and
3, they must be incorporated on two channels (x, y paths). Single-channel incorporation
into the control (z path) is only possible with a single-channel control and taking the risk
analysis into account.
2) To indicate the status on both sides, the MFP 1 connections from the sender and receiver
must be connected to each other in the control cabinet (optional).
3) SELV/PELV safety extra-low voltage.

Connection of a deTec4 safety light curtain to a RLY3-OSSD1 safety relay. Operat‐
in
g mode: With restart interlock, external device monitoring (EDM), and application
diagnostic output.
•
Mode of oper
ation
If the protective field is clear and the RLY3-OSSD1 is in a fault-free de-energized
posit
ion, the field indicator and the H2 lamp flash. The system can be switched
on. The system is enabled by pressing S1 (pushbutton is pressed and released).
