" N/A " denotes a condition where circuit fault does not apply.
*1 At an internal safety circuit fault, E.SAF or E.CPU is displayed on the operation panel. SA is displayed on the operation panel
while S1 and S2 signals are both open and the safety function operates (without internal safety circuit fault).
*2 To use RUN terminal for monitor output of failure detection, the parameter No.190 should be set 81 (Safety monitor 2).
*3 To use A,C terminal for monitor output of failure detection, the parameter No.192 should be set 81 (Safety monitor 2).
