Task
Connection of a deTec4 Core safety light curtain to UE48-2OS.
Operating mode: with restart interlock and external device monitoring.
Function
When the light path is clear, the OSSD1 and OSSD2 outputs are live. The system is ready to switch on if K1 and K2 are de-ener-
gized. By pressing S1 (button is pressed and released), the UE48-2OS is energized and its 13 - 14 and 23 - 24 contacts activate K1
and K2. On interruption of one of the light beams, the UE48-2OS is de-energized by the OSSD1 and OSSD2 outputs and K1 and K2
are deactivated.
Fault analysis
OSSD cross-circuits and short-circuits are detected and lead to the inhibited state (lock-out). The incorrect functioning of one of the
K1 or K2 contactors will be detected and does not result in the loss of the shutdown function. Jamming of the S1 button will pre-
vent the UE48-2OS from enabling.
Comments
1) _{Output circuits: These contacts are to be connected to the controller such that, with the output circuit open, the dangerous state}
is disabled. For categories 4 and 3, the integration must be dual-channel (x/y paths). Single-channel integration in the control (z
path) is only possible with a single-channel control and by taking the risk analysis into account.
