TMS7 soft starter · taken from the manufacturer’s manual, pages cited

Fault code0

The TMS7 has detected a shorted SCR(s). The manual's first action is: “1. Determine the affected phase using the 3 phase indicators LEDs located on the left hand side of the TMS7 cover. Damaged SCRs are indicated by an extinguished phase indicator LED (all phase indicator LEDs should be illuminated when input voltage is present but the motor is not running). SCR damage can be verified using the Power Circuit Test described in the Test & Measurement chapter of this section. 2. Replace the damaged SCR. 3. Reset the trip condition by removing and reapplying control voltage to the TMS7.”
