SECTION 6 Troubleshooting

ESP 400C and 600C Plasma Power Sources

6-2

Fault Indicator (Front Panel)

Illuminates when there are abnormalities in the

cutting process or when the input voltage falls

±10% outside the normal value. Momentary

illumination is normal. If continuously lit, check

LEDs 3, 4, 5, 7, and 8 on PCB1 for further

diagnosis.

LED 3 – (amber) Bus Ripple Fault -

Momentarily illuminates at the beginning of each

cut. Continuously lit during single-phasing or

imbalanced line-to-line voltages of the three phase

input line.(Excessive Ripple) Power Source is shut

down.

LED 4 – (amber) High Bus Fault – Illuminates

when input line voltage is too high for proper

operation (approx. 20% above nominal line voltage

rating). Power source is shut down.

LED 5 – (amber) Low Bus Fault – Illuminates

when input line voltage is approx. 20% below

nominal line voltage rating. PS is shut down.

LED 7 – (amber) Arc Voltage Saturation Fault

– Illuminates when the cutting arc voltage is too

high and cutting current drops below preset level.

LED will extinguish after voltage decreases and

current rises.

LED 8 – (amber) Arc Voltage Cutoff Fault –

Illuminates when arc voltage increases over the

preset value. PS is shut down.
