It sounds like you're referring to a fault related to a T3 PCB (Printed Circuit Board) in a tension assembly, possibly in the context of machinery or industrial equipment. Here's a potential description of the issue:
Fault Description: The T3 PCB in the tension assembly has failed or is malfunctioning, leading to improper regulation of tension within the system. This may result in issues such as inconsistent tension, improper operation of the tension control system, or complete failure to maintain the desired tension levels in the assembly.
The failure could be caused by:
Damaged components on the T3 PCB (such as resistors, capacitors, or transistors).
Broken or loose connections on the PCB, causing interruptions in the signal or power delivery.
Corrosion or contamination on the PCB, particularly if exposed to harsh environmental conditions.
Short-circuiting due to faulty wiring or grounding issues.
Symptoms of failure might include:
Erratic tension adjustments or an inability to control the tension properly.
Unexpected stops or malfunctions in the tension assembly.
Error codes or warning lights indicating a failure in the control system.
Inconsistent performance or wear on components due to improper tension.
Resolution:
Inspect the PCB visually for obvious damage such as burnt areas, broken components, or loose connections.
Use a multimeter or diagnostic tools to test the PCB for electrical faults.
Replace damaged components or the entire PCB if necessary.
Ensure proper grounding and connections are intact.
If this doesn’t exactly match your situation, could you provide more context or clarify the specific type of machinery or system you're working with?
