■Output interlock cancellation
After causes of the external power supply voltage error are eliminated, the safety output control will start by canceling the
output interlock by the CPU module.
Ex.
For the NZ2GFSS2-32D-S1
Operating procedure
1.
After checking that External power supply status is on, turn on Safety output control initial processing request flag
(SA\Y2E).
2.
After checking that Safety output control initial processing completion flag (SA\X2F) is on, turn off Safety output control
initial processing request flag (SA\Y2E).
3.
After checking that Safety output control initial processing completion flag (SA\X2F) is off, turn on Safety output control
start flag (SA\Y2F).
4.
After checking that Safety output control READY (SA\X2E) is on, turn off Safety output control start flag (SA\Y2F).
5.
After Safety output control READY (SA\X2E) becomes on, safety outputs and test pulse outputs will start.
