beams from another
sender cannot hit the
receiver, see "Protec‐

A fault or unexpected
s
tatus was identified on
the OSSDs of the sys‐
tem connection
(e.g., overvoltage,
short-circuit to HIGH or
short-circuit to LOW,
cross-circuit, permissi‐
ble load capacity
exceeded)
Check the system
wiring for a fault. Make
sure that the OSSDs
have been wired cor‐
rectly, see "Integrating
into the electrical con‐
trol", page 19. Switch
the voltage supply off
and then on again. If
the fault persists,
replace the defective
components, see
