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 para- meters (safety integrity level and response time) are dependent on the types used.
