When the reset switch is
pressed, the
M+SF_MUTES_R safety
output (SA\M1) is turned on,
enabling the M+SF_EDM_R.
The contactor output remains
on even though the light of the
light curtain is blocked only
when four muting sensors
detect the workpiece at the
correct timing in the correct
sequence.
When the start switch is
pressed, the M+SF_EDM_R
safety output is turned on
and the contactor output
(SA\Y0) turns on.
When an error occurs in a safety remote I/O module,
inputs and outputs of the safety remote I/O module
are turned off.
Also, the M+SF_MUTES_R and M+SF_EDM_R are
disabled.
A safety remote I/O
module detects a
double input
discrepancy.
