Min Supply Voltage μC1 Not Met

¿Qué significa 0103 hex ?

This diagnostic code (found within FA00:03 Supply error) signifies that the supply voltage to the primary microcontroller (μC1) has fallen below its minimum permissible limit. Undervoltage can lead to unstable operation, incorrect processing, or unexpected shutdowns of the terminal, affecting its safety functions.

• The supply voltage connected to microcontroller 1 (μC1) has fallen below its minimum required threshold.
• Undervoltage condition on the power supply line to μC1.
• Power supply instability or brownout affecting μC1.

1. 1

   Measure the input supply voltage to the EL6900 terminal using a multimeter at the power terminals.

2. 2

   Verify that the external power supply unit providing power to the terminal is operating within its specified voltage range and can supply adequate current.

3. 3

   Inspect the power supply cables and connections for any signs of voltage drop or loose contacts.
