Internal Terminal Temperature Too Low

What does Diag 2 Flash 7 mean?

The internal temperature of the terminal has fallen below its specified operating range. This cold condition can negatively impact the performance, response time, and reliability of the internal electronics and overall safety functions. Continued operation outside the specified temperature range may lead to malfunction or damage to components.

Complete Troubleshooting Guide

1. 1

   Ensure the ambient temperature in the control cabinet complies with the specified operating temperature range for the terminal.

2. 2

   Check for any direct exposure to cold air drafts or nearby cooling elements that might be causing localized low temperatures.

3. 3

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