SCF

Short Circuit

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Perform an insulation resistance test on the motor windings and cables to ground and between phases.

  2. 4

    If connections and insulation are confirmed to be satisfactory, contact Schneider Electric services as the fault may be internal to the soft starter.
