Common faults
What usually fails on a unit like the ATS48C47M
Soft starters are simpler than drives, but they work hard: every start pushes high current through the thyristors. Most faults are in the power section, the bypass contactor or the control card.
Shorted thyristors
A shorted thyristor makes the motor start direct-on-line or trips the starter on a phase fault.
Bypass contactor or relay wear
Worn bypass contacts overheat once the motor is up to speed, causing thermal trips after the start.
Overheating from frequent starts
Starts per hour above the rating, or blocked cooling, cause thermal trips and long-term thyristor damage.
Control card faults
A dead display, no start command response or wrong current readings point to the control electronics.
Phase loss and imbalance trips
Often the supply or motor, but sometimes the starter's own current sensing.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Note the trip message and whether it happens during or after the start.
- Measure supply voltage on all phases.
- Count starts per hour against the starter's rating.
Leave to a specialist
- Testing thyristors and the bypass circuit.
- Adjusting current limit and ramp settings for a heavy load.
- Any work inside the starter with the supply connected.
Getting it fixed

FAQ
ATS48C47M repair questions
Why does the Schneider Electric ATS48C47M trip only after the motor reaches speed?+
That usually points to the bypass contactor or its control, or to heat building up in the starter. Both are checked during the repair.
Does the Schneider Electric ATS48C47M have to be sent in, or can an engineer come to the plant?+
Either. An engineer can diagnose it in place and repair it there or take it away, or the unit can be sent to MachineryFix from anywhere in India. The diagnosis and repair cost are confirmed before any work starts.
Is MachineryFix connected to Schneider Electric?+
No. Schneider Electric and the model name are used only to identify the equipment. MachineryFix is an independent repair service and is not affiliated with or endorsed by Schneider Electric.
