Temperature Fell Below Minimum

Was bedeutet 0006 hex ?

This diagnostic code (found within FA00:03 Temperature error) indicates that the internal temperature of the device has dropped below its minimum permissible operating limit. This can affect the functionality of the primary and secondary microcontrollers (μC1, μC2) and may lead to unreliable operation or terminal shutdown.

• Ambient temperature or internal component temperature has dropped below the predefined minimum operating limit.
• Operation in an environment with insufficient heating.
• Sensor failure reporting an incorrect low temperature.

1. 1

   Check the diagnostic object FA80:01 (Temperature Primary MC) and FA80:02 (Temperature Secondary MC) to monitor current internal temperatures.

2. 2

   Verify the ambient temperature around the EL6900 terminal does not fall below the specified operating limits.

3. 3

   Ensure the EL6900 terminal is installed in an environment with adequate thermal insulation if operating in cold conditions.
