Task
Connection of a deTec4 Core safety light curtain to a UE48-2OS.
Operating mode: With restart interlock and external device monitoring
Mode of operation
When the light path is clear, the OSSD1 and OSSD2 outputs carry voltage. When K1 and K2 are in a fault-free de-energized posi-
tion, the system can be switched on and waits for an input signal/switch-on signal. The UE48-2OS is switched on by pressing and
then releasing the S1 pushbutton. The outputs (contacts 13- 14and 23- 24) switch the K1 and K2 contactors on. When one or
more light beams are interrupted, the OSSD1 and OSSD2 outputs switch off the UE48-2OS. Contactors K1 and K2 are switched
off.
Fault analysis
Cross-circuits and short-circuits of the OSSDs are recognized and lead to the locking state (lock-out). A malfunction with one of the
K1 or K2 contactors is detected. The shut-down function is retained. In the event of manipulation (e.g., jamming) of the S1 push-
button, the UE48-2OS will not re-enable the output current circuits.
Comments
1)
Output circuits: These contacts must be incorporated into the control such that the dangerous 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.
