 Troubleshooting 

 
If you think a failure has occurred, first turn off the unit and check the following items. 
They are not always a failure in the following cases, check the unit once again before requesting our services. 
 

Problem 

Items to check 

No output 
or the output does not meet 
the preset value. 

☐

 Is the input voltage within the specifications? Is the wiring correct? 

☐

 Is the CV and/or CC setting minimized? 

☐

 Is the [OUTPUT ON/OFF] switch set to ON? 

☐

 Is the [Romote/Local] selector switch set correctly? 

☐

  Restore  the  default  settings,  set  the  [Remote  Sensing]  and  [Single  Control] 

switches to OFF to output again. 

☐

 Is the common grounded in your equipment? (See 7-3.) 

Fuse blows 
or breaker trips 

☐

 Have you replaced the original screws of the housing with different ones? 

(The replaced screws may have cut into the internal circuits.) 

☐

 Is the breaker's base capacity sufficient? 

Output voltage fluctuates 
  or gets out of control. 

☐

 Is it set to CC mode? 

☐

 Is the input voltage within the specifications? 

☐

 Are there any noise sources near the unit?   

Ripple  voltage  is  large  or 
oscillating. 

☐

 Is the input voltage out of the specifications?   

☐

 Is a special load connected?   

☐

 Are there any sources for strong magnetic fields or electric fields near the 

unit? 

 

* 

If any of the above items do not apply to you, or if you have checked but cannot recover, please 
contact our sales office where you purchased the product.
