4.2 Operating explanation 

After than AC-voltage input is transforming into DC voltage, constant value is made to amplify and it considers 
as the input of comparator.   
And, the reference voltage obtained from the control power source is divided in a setting part's digital switch, 
this is considered as the input of the comparator of another side, and voltage comparison is performed.  
An output operates a relay through a drive circuit.  

 
 
5. Maintenance 
5.1 Maintenance 

The quality of this product is secured enough.  However, also in order to prevent an accident beforehand, please 
check an operation value periodically.  

 

< Caution > 
(1) Please do not make a wiring change of the input and auxiliary supply in an energization. 
(2) Please check a connection diagram, in case you check the voltage of input, output, and auxiliary supply. 

 
5.2 Countermeasures against troubles  

As our principle, we recall product in question and repair it.  If judged as product failure, have a contact with 
us or sales agent for repairing work (Also have a contact with us or sales agent for specification change). 
Product failure which we are not responsible for (When responsibility in manufacturing process is not recognized, 
when product is disassembled/remodeled, in case of false operation by customer, etc.) is beyond our warranty.
