Please observe the respective operating instructions of the integrated devices!
5.7.1 C4000 Basic on UE48-20S/UE48-30S with restart interlock and EDM
The C4000 Basic light curtain can be integrated in the switching amplifiers UE48-20S or
UE48-30S. Operation is carried out with restart lock and EDM.
Mode of operation:
If the light path is not interrupted, the outputs OSSD1 and OSSD2 are energised. The
system is ready to switch on when K1 and K2 are in the de-energised position. Pressing
the button S1 switches on the UE48 switching amplifier. The contacts 13-14 and 23-24 of
the UE48 activate the contact elements K1 and K2.
If the light path is interrupted, the outputs OSSD1 and OSSD2 are de-energised. This
switches off the UE48 and deactivates K1, K2.
Possible fault sources:
Cross and short-circuiting of the outputs OSSD1 and OSSD2 are detected and lead to a
lock-out. Malfunctions of the contact elements K1 and K2 are detected; the switch-off
function remains active.
