Over Temperature Fault:

Indicates that the internal oil temperature has exceeded 65° C. The high voltage output will be disabled. Toggling the X-Ray ON Command OFF and ON will reset the fault.

Over Voltage Fault:

An overvoltage (OV) fault is detected when the output voltage exceeds 82kV. The high voltage output will be disabled. Toggling the X-Ray ON Command OFF and ON will reset the fault.

Current Accuracy:

Current measured through the X-Ray tube is within ±2.5% of the programmed value

Over Current Fault:

An overcurrent (OC) fault is detected when the emission current exceeds 275µA (20W model) and 710µA (50W model). Toggling the X-Ray ON Command OFF and ON will reset the fault.

Arc Intervention:

One arc fault. The high voltage output will be disabled. Toggling the X-Ray ON command OFF and ON will reset the fault.
