Task
Integration of three cascaded L4000 (L41) family single-beam photoelectric safety switches with a UE410-MU/XU safety controller
into a relay controller/contactor controller.
Operating mode: with restart interlock and with external device monitoring.
Function
When the input conditions are valid, the system is ready for switch-on and waits for an input signal/switch-on signal. The system is
enabled by pressing and releasing the S1 button. The related output on the UE410-MU/XU carries power. If the input conditions are
no longer met, the related outputs on the UE410-MU/XU shut down.
Possible faults
The incorrect function of the K1 and K2 contactors will be detected. The shutdown function is retained.
On manipulation (e.g., jamming) of the S1 button, the system does not enable the output current circuits.
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.
2)
PELV as required in EN 60204-1 / 6.4
Optical short-circuits must be avoided. Take note of the operating instructions for the integrated devices. The safety-related parameters (safety integrity level and response time) are dependent on the types used.
