What should I do if my ABB PSTX370 displays 'Heatsink overtemperature'?
Ensure that the fans are functioning correctly and that the airways are free from dirt and dust. Also, verify that the ambient temperature is not too high. If the fault persists after a reset, the heatsink is still too hot and needs to cool down.
What does it mean when my ABB PSTX370 displays 'Under voltage'?
An undervoltage error indicates that the main voltage is too low. Perform a check of the main voltage.
What does it mean when my ABB Controller displays 'Overvoltage'?
An overvoltage error indicates that the main voltage is too high. Perform a check of the main voltage.
What should I do if my ABB PSTX370 displays 'Locked rotor'?
Examine the bearings of the motor and the load to ensure they run easily. A damaged bearing or a load stock could be the cause.
What does it mean when my ABB PSTX370 Controller displays 'Ground fault'?
A ground fault indicates that the sum of the instantaneous line currents in your 3-phase system differs more than the specified value. Examine the motor cables and the motor itself for any issues.
