Environment Error: μC1 maximum supply voltage exceeded

¿Qué significa 1 ?

When LED Diag 1 is off and LED Diag 2 flashes with code 1 (400ms ON / 400ms OFF), it indicates that the internal supply voltage for microcontroller μC1 has exceeded its maximum permissible limit. This environment-related error signals an overvoltage condition, potentially risking damage to the μC1 or compromising its safety functions due to electrical stress.

• External power supply providing voltage exceeding the maximum rated input for μC1.
• Faulty voltage regulator circuit within the device.
• Transient voltage spikes on the power input.
• Incorrect wiring of the primary power source to the device terminals.

1. 1

   Measure input voltage at the power supply terminals (e.g., L1, L2) to confirm it's within specified range (e.g., 110V-230V AC).

2. 2

   Verify device's internal DC bus voltage, if accessible, is not exceeding its design limit.

3. 3

   Inspect power input terminals for signs of overheating or damage.

4. 4

   Disconnect external power and allow device to discharge before re-applying power.
