FAULT DESCRIPTIONS (continued)

Overload Fault (OL)

This fault will occur if the current output reaches 90uA.

Remove the condition causing excess microamps and reset the fault. Typically the target distance from the probe to the

part is too close. Back up target distance and re-calibrate.

Low Current Set point Fault (LC)

This fault will occur if the set point is set below a factory preset threshold. This is to prevent unacceptable calibration

values. If this occurs use an insulation test meter with at least 1KV output (Megger), to check that the target is properly

grounded, and verify the target distance is 4 inches, then re-calibrate the unit. To recover from a LC fault the calibration

must be set very quickly, then go back and allow the voltage to settle and reset the set point again.

Current Limit Fault (CL)

This fault will occur if the output current exceeds the maximum current by more than 20 uA for 2-3 seconds. If this oc-

curs, reset the fault from the applicator or control unit. If this fault occurs repeatedly, investigate the main PC board or

applicator barrel for the cause.
