Does the alarm condition continue to be present?

 

 

 

If alarm condition is present, remove rectifier and replace

Do all appear to be okay? 

 

 

If okay, contact PECO II service following the instructions 
on page 6 of 127NHL manual.

system. (During installation, an external FA can be 
connected to the rear of the plant to monitor for an FA 
condition).
