How to resolve Jam error on Allen-Bradley Controller?
If your Allen-Bradley Controller indicates a jam, it means the motor current has exceeded the user-programmed jam level. Correct the source of the jam or excessive loading and check the programmed time value.
What does Underload mean on Allen-Bradley SMC-50?
An underload situation with your Allen-Bradley Controller can be due to a broken motor shaft, belts, tool bits, pump cavitation, or an incorrect user setting. Check the pump system, machine drive components, and loading. Also, check the settings and repair or replace the motor as needed.
What causes Shorted SCR with Phase Indication on Allen-Bradley Controller?
A shorted SCR with phase indication on your Allen-Bradley Controller is typically caused by a shorted power module. Check for a shorted SCR and replace the power module if necessary.
