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.

②  External device monitoring is only static.

③  SELV/PELV safety/protective extra-low voltage.

Task

Connection of a deTec4 Prime safety light curtain to a UE48-2OS safety relay. Operating mode: with restart interlock and external

device monitoring (EDM). The T-piece establishes a connection between the sender and the receiver.

Mode of operation

When the protective field is clear, the OSSD1 and OSSD2 outputs carry voltage. The system can be switched on when K1 and K2

are in a fault-free de-energized position. The UE48-2OS is switched on by pressing S1 (pushbutton is pressed and released). The

outputs (contacts 13-14 and 23-24) switch the K1 and K2 contactors on. When the protective field is interrupted, the OSSD1 and

OSSD2 outputs switch the UE48-2OS off. Contactors K1 and K2 are switched off.

Fault analysis

Cross-circuits and short-circuits of the OSSD1 and OSSD2 outputs are recognized and lead to the locking state (lock-out). A mal-

function 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 pushbutton, the UE48-2OS will not re-enable the output current circuits.

Task

Connection of two deTec4 Prime safety light curtains to a UE10-3OS safety relay. Operating mode: without restart interlock, with ex-

ternal device monitoring (EDM). If required, the restart interlock is implemented via the machine controller.

Mode of operation

If the protective field is clear and the UE10-3OS is in a fault-free de-energized position, the system is enabled. Outputs OSSD1 and

OSSD2 carry voltage, the UE10-3OS is switched on. When the protective field is interrupted, the OSSD1 and OSSD2 outputs switch

the UE10-3OS off.

Fault analysis

Cross-circuits and short-circuits of the OSSDs are recognized and lead to the locking state (lock-out). The malfunction of the

UE10-3OS is detected. The shut-down function is retained.

Task

Connection of a deTec4 Prime safety light curtain to a UE10-3OS safety relay. Operating mode: with restart interlock, external de-

vice monitoring (EDM), and application diagnostic output.
