Minor Faults and Alarms

Refer to

Table 5.3

for an overview of possible alarm codes. Conditions such as overvoltages can trip faults and alarms. It

is important to distinguish between faults and alarms to determine the proper corrective actions. When the converter
detects an alarm, the ALM indicator LED blinks and the alarm code display flashes. Most alarms trigger a digital output
programmed for alarm output (H2- = 10). A fault (not an alarm) is present if the ALM LED lights without blinking.
Refer to

Faults on page 106

for information on fault codes.
