Press the reset button for 1 second. You will hear an audible "Click" – this is the internal relays energizing. The "Out" LED turns green.
Ensure the contactor (the machine's main switch) is healthy. The feedback LED should flash once. Xtra Safe Kt 82001 Manual
A: Yes. The manual certifies the KT 82001 up to SIL CL 3 per IEC 61508 and PL e (Category 4) per ISO 13849-1. Press the reset button for 1 second
Close all safety gates and pull out all E-stop buttons. The "In 1" and "In 2" LEDs should turn green. Ensure the contactor (the machine's main switch) is healthy
A: The manual specifies mechanical longevity of 10,000,000 cycles, but electrical longevity (switching under load) is 100,000 cycles at rated current (6A).
| LED Status | Error Description | Manual Solution (Page 22-24) | | :--- | :--- | :--- | | | Overvoltage (>30V DC) | Reduce voltage immediately. Unit may be damaged. | | "In 1" flashing red | Channel 1 stuck closed | Replace the E-stop button or safety switch. | | "In 2" off, "In 1" on | Mismatched input timing | Inputs must change state within 0.5 seconds of each other. Check wiring symmetry. | | "Out" flashing yellow | Feedback loop broken | Check the auxiliary contacts on your external contactors. | | All LEDs cycle | Internal watchdog fault | Cycle power.
