Table 4:  

Converter Module Troubleshooting 

Symptom 

Possible Cause(s) 

Suggested Action(s) 

 

Power 

Indicator 

(Green) Off 

No input voltage. 

Make sure there is input voltage. 

Internal input fuse 

open. 

Replace the converter. 

 

Protection 

Indicator 

(Yellow) On 

DC input under/over 

voltage. 

Correct the DC input voltage to within the 

acceptable range. 

Moderate load sharing 

imbalance. 

Check if the converter is properly seated in 

the module mounting assembly.  If this does 

not correct the fault, replace the converter. 

Converter not 

inserted into the slot 

completely. 

Remove and properly insert the converter. 

Converter over-

temperature 

protection. 

Fan rotor blocked:  remove any object that 

may be blocking the fan. 
Ventilation blocked (inlet or outlet):  remove 

any object that may be blocking the inlet or 

outlet. 
Ambient temperature too high or rectifier inlet 

too close to a heat source:  lower the ambient 

temperature or relocate the heat source. 

Converter in ECO 

Standby Mode when 

ECO Mode is active in 

controller. 

-- 

Protection 

Indicator 

(Yellow) 

Flashing 

Loss of 

communication with 

controller (the 

converter can provide 

power). 

Check the communication cables. 
Remove and properly insert the converter. 

 

Alarm 

Indicator 

(Red) On 

Severe load sharing 

imbalance. 
Converter output 

disabled for any 

reason, including 

overvoltage shutdown. 

Remove the converter, wait 30 seconds or 

more (until the LEDs on the converter 

extinguish), then re-insert the converter.  If 

converter fails to start, shuts down again, or 

load sharing imbalance persists; replace the 

converter. 

Alarm 

Indicator 

(Red) Flashing 

One or both fans not 

operating (converter 

shuts down). 

Replace the fan(s).
