Internal Terminal Temperature Too High

What does Diag 2 Flash 8 mean?

The internal temperature of the terminal has exceeded its specified operating range, indicating overtemperature for internal microcontrollers (μC1 or μC2). This can lead to reduced performance, component degradation, thermal shutdown, or even complete failure of the terminal, compromising safety. Prompt resolution is required to prevent permanent damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check for excessive load on the terminal's outputs or other nearby components that might be generating additional heat.

2. 4

   Take suitable EMC measures if electromagnetic interference is suspected to be contributing to internal heating. If the issue persists, replace the terminal.
