Troubleshooting 

If trouble is suspected, check out the following points before requesting servicing. 

 

①

 No power. 

 

・

Has the power connector been inserted all the way in? 

 

・

Is the correct voltage (+12 V to +24 V) being supplied? 

 

・

Is the power connector wired correctly? 

 

・

Does the power source have a sufficient capacity (W)? 

 

②

 No communication. 

 

・

Has the RS-232C or Ethernet connector been inserted all the way in? 

 

・

Are the same communication settings used for both the host unit and MG80-SC? 

 

・

Is the cable too long? 

 

・

Are any cables carrying heavy currents from motors or other devices positioned near the communication cable? 

 

③

 Problem in the count reading. 

 

・

Has the count value overflowed? 

 

・

Is the alarm lamp on the MG80-SC lit? 

 

④

 Count reading does not change. 

 

・

Is it latched or paused? 

 

・

Is the peak value mode set? 

 

・

Is the communication working correctly? 

 

・

Are the measuring sensors connected to the counter modules? 

 

・

Are the data request commands being output correctly?
