Fault

¿Qué significa E46.51 ?

The safety option is reporting a standard subcomponent fault, leading to an emergency stop and output stage inhibit. This indicates a significant problem within the safety circuit that requires immediate resolution to restore safe and operational status.

• Failure of a critical safety input sensor (e.g., broken wire to emergency stop, shorted safety gate switch).
• Internal hardware failure within the safety option affecting a safety-critical path (e.g., watchdog timer failure, processor fault).
• Discrepancy detected between redundant safety channels that exceeds the configured tolerance (e.g., P7-10 Discrepancy time).
• Unstable power supply (e.g., voltage sag below 18VDC) to the safety option causing internal resets or logic errors.
• External short circuit or overload on a safety output of the option card.

1. 1

   Check the status of all connected safety input devices (e.g., E-stop, safety gates) and measure their voltage levels at the safety option terminals.

2. 2

   Inspect all wiring connected to the safety option for damage, shorts, or open circuits.

3. 3

   Utilize the safety option's diagnostic software or LEDs to identify the specific internal subcomponent fault code.

4. 4

   Verify the power supply voltage (e.g., 24VDC) at the safety option's input terminals is stable and within tolerance.

5. 5

   Perform a functional test of each safety input, observing the status changes on the safety option's diagnostics.
