Fault Generation The following sequence occurs when the protection circuits generate a fault. The fault source is latched, the output stage is disabled, the Fault mappable output function is activated, and the LED indicates the appropriate fault code. Faults are cleared by activating the Fault Reset input or by turning the 120/240 VAC Control Power OFF and then ON again.
