Complete Troubleshooting Guide

1. 1

   Check the actual signal level at the affected analog input (e.g., AI1, AI2).

2. 2

   Examine the auxiliary code for specific details (e.g., LessMIN, GreaterMAX) if visible on the control panel.

3. 3

   Inspect the wiring connected to the analog input for breaks, shorts, or interference.
