Schneider Electric · Altistart 22 Soft Starter
What does SCF mean?
A short circuit has been detected on the soft starter's output, typically between motor phases or from a phase to ground. This is a severe fault that can cause immediate and significant damage to the soft starter and motor.
Complete Troubleshooting Guide
- 1
Switch off the soft starter and disconnect power immediately to prevent further damage.
- 2
Thoroughly check all motor connections for any short circuits, loose wiring, or damage.
- 3
Perform an insulation resistance test on the motor windings and cables to ground and between phases.
- 4
If connections and insulation are confirmed to be satisfactory, contact Schneider Electric services as the fault may be internal to the soft starter.
