Check if the PIN of the IO card is broken.
Check if the IO card connects to the control board correctly, and if the screws
are tightened well.
STO1 and SCM1, or STO2 and
SCM2 short circuit lines are not
connected
STO2 and SCM2 short circuit lines
are not connected
Re-connect the short circuit lines
