Troubleshooting AMX
Error Number
24 V debug-header value low or zero
Error Code / System Message
24V debug header
Error Question
What does low or zero 24 V on the Definium AMX 700 debug header indicate?
Short Answer
Very low 24 V suggests a current overload; 0 V can result from converter over-temperature, input over/under-voltage, converter failure or other supply faults.
Possible Causes
24 V output overload; converter over-temperature; input voltage fault; converter failure.
Troubleshooting Steps
Measure debug-header connection 1. If very low, isolate 24 V loads for overload. If 0 V, check converter temperature/input conditions and the converter itself.
