● ● ● Frequency error No 1L1 phase of frequency Check 1L1 phase and/or main
48Hz <f main < 62 Hz) is out of range frequency
● ● Phase sequence loss Disturbance in supply voltage Check notches or dropouts in power line
Defective thyristor Check thyristors
No input phases Check 1L1, 3L2 and 5L3 phases
● ● ● ● Synchronism loss Phase 1L1 lost Check 1L1 phase, ground connection
and/or output voltage to ground
● ● ● A Phase A, B, C Short-circuited thyristor Check thyristor module
● ● ● B thyristor No output phases Check 2T1, 4T2 and 6T3 phases
● ● C
● ● ● A Phase A, B, C lost No input/output phases Check power wire harness for
● ● ● B 1L1, 3L2, 5L3, 2T1, 4T2 and 6T3
● ● C Defective thyristor or bad Verify gate and cathode wire
wire harness harness and verify thyristors
● Internal failure Microcontroller malfunction Check that IC2 is correctly inserted
