Rectification
Check the system wiring for
a fault. Make sure that the
OSSDs have been wired
correctly, see "Integrating
into the electrical control",
page 20. Switch the voltage
supply off and then on
again. If the fault persists,
replace the defective com‐
ponents, see "Ordering
information", page 53.
