AC-2000 

|

 8.10/8.11 

 

 
Problem

:

 Relays do not operate 

Solution

:

 

1.  If only one relay is not working, check the related fuse. 

2.  If a group of 4 or 8 relays are not working, it could be that one of the relay coils shorted 

causing the thermal fuse (automatic fuse) to short. 

 
Problem

:

 Sporadic resets caused by interference 

Solution

:

 

•

  It is recommended to install a snubber at the source of interference (for example contactors or 

motors).
