•Status register 

It is possible to check the peripheral fault error (a blown input block fuse or detecting over current of input 
power supply) by monitoring the status bit S1, which complies with the AS-i Version 2.1. 

 

 

 

It is possible to confirm the peripheral fault error only by status register on the ADDR1 side for 
EX250-SAS3/-SAS7 which occupy 2 slaves. 

 

Note 

Turn off the power supply and remove the cause immediately when over current load is connected with 
the input block, and the peripheral fault error occurs by over current detection. Using with the peripheral 
fault error can cause unit damage.
