Warning

What does E46.50 mean?

The safety option is signaling a subcomponent fault of a warning type. This indicates a non-critical issue within the safety circuit that could affect safety integrity or system reliability if not addressed, potentially escalating to a more severe fault.

• Marginal signal levels on a safety input (e.g., E-stop, safety gate switch) due to long cable runs or degraded contacts.
• Temporary discrepancy or jitter in redundant sensor inputs (e.g., cross-monitoring of two safety limit switches).
• Internal diagnostic routine in the safety option detected a parameter outside warning limits (e.g., minor internal voltage drift).
• Minor electromagnetic compatibility (EMC) disturbance affecting the robustness of the safety option's operation.
• Approaching end-of-life or degradation of an internal component on the safety option card.

Click steps to track your progress.

1. 1

   Verify the integrity of all external safety input wiring, checking for correct resistance values (e.g., <5 ohms) across connections.

2. 2

   Check the voltage levels at safety input terminals (e.g., X1, X2) to confirm they are within the specified operational range (e.g., 24VDC).

3. 3

   Review the safety option's diagnostic screen or LEDs for specific subcomponent warning codes.

4. 4

   Temporarily disable high-noise sources (e.g., switching power supplies) near the inverter to rule out EMC as a cause.

5. 5

   Consult the safety option manual for specific warning code meanings and recommended preventative maintenance.
